Problems solved by technology

Water-based anti-corrosion coatings contain a variety of additives, and their film-forming methods are different from solvent-based coatings. These factors will have a great impact on the performance of the coating film, so the development of water-based anti-corrosion coatings is slower than other water-based coatings.

Embodiment example 1

[0011] The amount of pigments and fillers in the paint is relatively large. After the paint is dried, the pigments and fillers are uniformly dispersed in the polymer film in the form of solid particles, which play the role of filling enhancement, cost reduction and endowing the paint with some special properties. Pigments and fillers are important components of the coating film, and the performance of the coating film varies greatly with different amounts. Pigment-base ratio has great guiding significance in determining the ratio of paint base and pigment in our formula development. Aluminum tripolyphosphate is used as an active antirust pigment, titanium dioxide is used as a filler, the mass ratio of aluminum tripolyphosphate to titanium dioxide is 5:3, and the purchased epoxy emulsion is used as a base material. The influence of different pigment-base ratios on the coating performance As can be seen, with the increase of the pigment-to-base ratio, the pencil hardness of the ...

[0013] As a reactive component, the curing agent cross-links with the epoxy resin to form a three-dimensional network structure. It is an integral part of the coating film after curing. Its addition directly affects the cross-linking process and the cross-linking structure of the coating film. The structure and performance of the coating film are affected. As the amount of curing agent increases, the pot life of the paint gradually decreases. The greater the content of the curing agent, the higher the concentration of the curing agent around the epoxy resin, the faster the curing speed, and the shorter the pot life of the paint.

Embodiment example 3

[0015] If the amount of curing agent is too low, the reaction between the epoxy resin and the curing agent will not be complete, and the epoxy resin will not be completely cured, and the formed coating film will not be dense enough, which will affect the hardness of the coating film; The water-based epoxy curing agent reacts, and the water-based epoxy curing agent is hydrophilic, which increases the hydrophilicity of the system, and increases the affinity with acids and alkalis, resulting in a decrease in the anti-corrosion performance of the system. When the amount of water-based epoxy emulsion is constant, the anti-corrosion performance and pencil hardness of the coating film increase slowly with the increase of curing dose. When the mass ratio of water-based epoxy emulsion and curing agent reaches 100:10, the overall performance of the coating is the best Well, then as the amount of curing agent increases, the pencil hardness of its corrosion resistance, bending resistance, ...

Abstract

The invention discloses a waterborne aluminum triphosphate coating. Various performances of a coated film are relatively balanced when the pigment binder ratio of a waterborne anticorrosive coating prepared from aluminum triphosphate is about 0.8. The working life of the coating is shortened along with the increment of the usage amount of a curing agent, and coatings with different working life can be prepared by regulating the usage amount of the curing agent, so that the demands of various construction conditions are met. The mass ratio of a waterborne epoxy emulsion to an epoxy curing agenthas great influence to the performance of the coated film, and various performance indexes of the coated film can reach relatively good balance when the mass ratio of the waterborne epoxy emulsion tothe epoxy curing agent is about 100:8. Various performance indexes of the waterborne anticorrosive aluminum triphosphate coating prepared according to an experiment reach or exceed national relevanttechnical indexes, and water is used as a solvent, so that the waterborne aluminum triphosphate coating is environment-friendly and safe and conforms to the relevant rules of an environment law.

Description

Technical field [0001] The invention relates to a coating, in particular to an aluminum tripolyphosphate water-based coating. Background technique [0002] In the 21st century, environmental protection has attracted more and more attention from the world. At present, domestic anti-corrosion coatings and solvent-based coatings mostly contain high organic volatiles, and some products contain harmful solvents such as benzene and glycol ethers, which cause great harm to the body of manufacturing and coating personnel and serious damage to the environment. Moreover, this kind of anti-corrosion coating contains heavy metal salt anti-rust pigments, such as red lead, yellow lead, strontium chrome yellow, zinc chrome yellow, tetrabasic zinc yellow, etc., which will cause soil pollution and endanger human health. In recent years, some water-based environmentally friendly bottom-surface anti-corrosion coatings have appeared abroad, with good performance, but mainly drying, high energy...
