Abstract

The invention relates to the technical field of chemical paint, in particular to a waterborne plastic paint and a preparing method and use method thereof. The waterborne plastic paint comprises, by weight, 40-80 parts of a modified acrylic resin emulsion, 4-8 parts of a water-soluble dispersant, 1-3 parts of a waterborne thickening agent, 0.6-1.0 part of a waterborne defoaming agent, 0.3-0.7 partof a waterborne flatting agent, 0.3-0.7 part of a waterborne wetting agent, 0.2-0.4 part of a waterborne antirust agent, 0.4-0.8 part of a multifunctional additive, 1-5 parts of other additives, 10-30parts of pigment powder and 40-80 parts of deionized water. The waterborne plastic paint solves the problems that waterborne paint has insufficient adhesive force on a plastic substrate and thermal-cured finish paint matched with waterborne paint has too many shrinkage holes; the waterborne plastic paint is high in adhesive force and extremely good in leveling property, and a paint film is outstanding in water resistance, high temperature resistance, temperature impact resistance and other performance.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to a water-based plastic coating and a preparation method and application method thereof. Background technique [0002] The perfect decorative and durable protective properties of coatings make the coatings industry develop rapidly. With the continuous strengthening of environmental protection awareness and the increasing improvement of environmental protection regulations, people's requirements for environmental protection and awareness of coating pollution are getting higher and higher. , various countries have strictly controlled the emission of VOC and restricted the production and use of high VOC coating products to the height of laws and regulations. [0003] In the wave of environmental protection, water-based coatings are an important trend and approach, but due to the high surface tension of water and plastics, the interface is difficult to wet, so at present, wat...
