I. definition analysis of water-based coatings

all coatings using water as solvent or dispersion medium can be called water-based coatings. Water based coatings include water-soluble coatings, water dilution coatings and water dispersible coatings (latex coatings). Water soluble coatings take water-soluble resin as film-forming material, represented by polyvinyl alcohol and its various modifiers. In addition, there are water-soluble alkyd resin, water-soluble epoxy resin, inorganic polymer water-based resin and other Chinese coatings

II. Product classification and product characteristics of water-based coatings

water based coatings include water-soluble coatings, water dilution coatings, and water dispersive coatings (latex coatings). Water soluble coatings take water-soluble resin as film-forming material and polyvinyl alcohol and its various modifiers as representatives. In addition, there are water-soluble alkyd resin, water-soluble epoxy resin and inorganic polymer water-based resin

1. It is a water-based wood paint with the composition of acrylic acid and polyurethane as the main component. In addition to adhering to the characteristics of acrylic paint, it also adds the characteristics of strong wear resistance and chemical resistance. Some enterprises mark it as water-based polyester paint. The film hardness is good, the pencil rule test is 1H, the fullness is good, and the comprehensive performance is close to oily paint. At present, only a few domestic enterprises can produce

2. It is a polyurethane waterborne paint with superior comprehensive performance, high fullness and film hardness of 1 H. The wear resistance is even better than that of oil-based paint. There is market cooperation in service life and color allocation. The modified plastic has obvious advantages in further improving. It is an advanced product in water-based paint. This technology can confirm the composition of abrasive particles according to color and shape all over the world. Only a few professional companies master it. In China, only Dongguan Dingyuan Industrial Co., Ltd. took the lead in completing the localization of the core technology, and has the national invention patent. The price of its "Green Bo" brand water-based paint is equivalent to that of the second type of water-based paint

3. It is a water-based wood paint with acrylic acid as the main component, which is characterized by good adhesion and will not deepen the color of wood, but poor wear resistance and chemical resistance, soft film hardness, pencil rule test Hb, poor fullness, general comprehensive performance, and easy to produce defects in construction. Because of its low cost and low technical content, it is the main product of most water-based paint enterprises to the market. This is also the reason why most people think that water-based paint is not good. Its advantage is low price

III. advantages of water-based coatings

first, the biggest advantage of water-based coatings is environmental protection. Water based coating is a coating that is dispersed and diluted with water or a small amount of film-forming material. It is characterized by environmental protection, non-toxic, not easy to burn, and does not contain carcinogens such as benzene and formaldehyde and heavy metals, which is relatively harmless to human health

second, the paint film has good performance and extends its service life. Water based coatings have properties that traditional coatings do not have, such as UV radiation resistance, smaller color difference, and longer life of the coating

third, good construction performance. In terms of dry time, construction temperature, recoating time and filling property, the two are equivalent, while the nonvolatile content of water-based coatings can be as high as%, and the traditional is only 20%. Waterborne coatings can effectively reduce the occupational disease incidence rate of construction workers

fourth, compared with traditional coatings, the paint film of water-based coatings has the same coating effect of improving the supporting policies. It can be painted with oil-based coatings, "one bottom and two sides", and water-based coatings can also be done. For painting, the cost of water-based paint is 20% - 50% higher than that of oil-based paint, and its operating cost will also increase greatly, which is not conducive to the promotion of water-based paint, but now this problem has been overturned. Moreover, in terms of its performance, the hardness, wear resistance and film surface fullness of water-based coatings meet or exceed those of solvent based coatings

IV. application fields of water-based coatings

water based industrial coatings are mainly used in the fields of automobiles, railway vehicles, bridges and pipelines, steel structures, containers and so on. At present, there is a big gap between the water-based level of domestic industrial coatings and industrial developed countries

automotive coatings

with the rapid development of the automotive industry, the amount of automotive coatings is also increasing. Since Shanghai General Motors launched its first water-based automotive paint production line in Shanghai in 2008, all new domestic automotive paint production lines have been designed with water-based paint, and water-based paint has become the mainstream of automotive paint. Automotive coatings mainly include primer, intermediate coat and finishing coat, of which the finishing coat is divided into natural color paint and metal flash paint. The hydration process of automotive coatings is carried out gradually from bottom to surface. As early as the 1960s, Europe, the United States and other developed countries have taken the lead in using water-based electrophoretic primers. At present, more than 90% of the primers have adopted water-based coatings, 88% of the automotive intermediate coating has also adopted water-based technology, and the application of water-based metal flash primer has exceeded 65%

railway vehicle coatings

traditional solvent based coatings are mostly used for body coating, which contains a large amount of organic solvents, which brings inconvenience and potential safety hazards to storage, transportation and construction. The harmful gases released during the production and use of solvent based coatings will have a negative impact on the health and atmospheric environment of the production staff, which takes up less space. In developed countries, powder coatings, 100% solid content liquid coatings and water-based coatings have become the mainstream coating systems in railway vehicle manufacturing industry, in which water-based coatings are more and more widely used. At present, more than 13000 vehicles have been successfully coated with Huabao waterborne industrial paint in the field of railway freight cars in China. The products have been verified for more than 5 years and can fully meet the quality standard of solvent based products; Huabao paint Co., Ltd. has also completed the development of waterborne coating system for railway locomotive and bus, and has begun on-line testing after coating. The localization and hydration of coatings in the fields of bullet trains, high-speed railways and rail transit have also entered the work plan of the general railway administration

heavy-duty anti-corrosion coatings

corrosion and rust of metal products can be seen everywhere in daily life, causing waste of resources and energy, economic losses, and sometimes even endangering personal safety. According to some corrosion loss data released by the United States, Japan, Canada and other countries, the direct economic loss caused by corrosion accounts for 1% to 4% of the gross national economic output value. The annual corrosion and rust of steel accounts for about 20% of the annual output, and about 30% of the equipment is scrapped due to corrosion. The annual economic loss caused by metal corrosion in China accounts for about 4% of the gross national product. Such amazing loss stimulates the development of anti-corrosion coatings. The development of environmental friendly industrial heavy-duty anticorrosive coatings is a high-tech project being actively explored by coating experts in many developed countries around the world, and it is an emerging field in China. In some typical Heavy-duty Coatings Markets, such as infrastructure, oil and gas, electricity, barrel tanks, marine and chemical industries, the use of water-based coatings is increasing. Water based alkyd system, water-based epoxy system (epoxy micaceous iron midcoat and epoxy zinc rich primer), water-based inorganic zinc rich system, and water-based epoxy ester system are used in the field of heavy corrosion protection

waterborne container coatings

at present, the annual output of containers in the world exceeds 3.5 million TEUs, and the annual demand for coatings is about 400000 tons, worth about 6billion yuan. At present, most of the container coatings used in the world are solvent based. In the process of container production and painting, a large number of harmful gases will be produced, which will not only endanger the health of painting operators, but also cause environmental pollution. With the increasingly stringent environmental protection regulations, the International Commission for container standardization has put forward higher requirements for the environmental protection and hygiene of container coatings: for example, the coatings shall not contain heavy metals such as CD, Pb, Cr, Hg; Non toxic pigments such as phosphate are used; High solid content, low VOC, etc. The substitution of acrylic topcoat for chlorinated rubber topcoat and special paint for box bottom has also been gradually promoted. Water based container coatings have been applied on a pilot basis in China
