Problems solved by technology

However, there are no water-based chameleon pigments in the market at present, mainly because of the constraints of related technical problems. One is to solve the problem of wetting and encapsulation of pigments by water-based resins, and the other is that due to the limitation of applicable fields, it has a certain impact on its wear-resistant and scratch-resistant performance. High requirements, and this is the shortcoming of traditional water-based coatings

Abstract

The invention provides a water-based chameleon solvent-resistant elastic coating, which comprises the following ingredients (by weight): 10-15 parts of deionized water, 40-60 parts of waterborne resin, 6-10 parts of chameleon pigment, 8-10 parts of a water-based curing agent, 2.5-5 parts of water-based matting powder, 0.3-0.5 part of a dispersant, 0.3-0.5 part of a wetting agent, 0.8-1.2 parts ofa leveling agent, 3-4 parts of a coalescing agent, 1-2 parts of a hand feeling agent, 1-2 parts of water-based wax, 0.1-0.3 part of an antifoaming agent, 0.1-0.3 part of a pH regulator, 0.2-0.4 part of a thickening agent, 2-3 parts of propylene glycol methyl ether acetate, and 1-3 parts of DB7650 special modified polyurethane. The coating is safe and environmentally-friendly, and has good solventresistance, film fullness, scratch resistance and wear resistance. In addition, hand feeling and application property are also greatly enhanced.

Description

technical field [0001] The invention provides a water-based solvent-resistant coating with a chameleon effect, which belongs to an environment-friendly water-based coating in the field of high-end decoration. Background technique [0002] There are mainly two types of coatings on the market, water-based coatings and solvent-based coatings (oil-based coatings). Solvent-based coatings do not have high requirements for painting conditions, and can be applied in a wide range of temperature and humidity. Solvent-based coatings have a thicker consistency and are not easy to flow; solvent-based coatings have good leveling properties, smooth paint films, and less brush or reel lines. The surface permeability of solvent-based paint is strong, especially for open-air wood, which can increase its adhesion and surface protection; the adhesion of oil-based paint is better on a smooth surface; solvent-based paint has a brighter and more eye-catching luster. However, with the implementat...
