Abstract

The invention relates to water based paint with a mirror surface effect and a preparation method thereof. The water based paint is composed of the following components in parts by weight: 50-70 parts of water-based acrylic resin A, 10-20 parts of water-based amino resin B, 5-10 parts of cosolvent, 0.1-0.5 part of defoaming agent, 0.5-1 part of leveling agent, 5-10 parts of effect pigment, 0.05-0.1 part of amine neutralizer and 10-20 parts of deionized water. The preparation method comprises the following steps: sequentially adding the water-based acrylic resin A, the water-based amino resin B, 50% of deionized water, the defoaming agent and the cosolvent into a container, and stirring uniformly to obtain a mixture A; uniformly mixing and stirring the residual deionized water, the leveling agent and the effect pigment to obtain a component B; adding the component B into the component A while stirring, uniformly stirring and finally regulating the pH to 7.0-7.5 by use of the amine neutralizer. Compared with the prior art, the water based paint provided by the invention has the advantages of low VOC emission, environmental friendliness, excellent adhesive force, high hardness and scratch resistance, and the like.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a water-based paint with a mirror effect and a preparation method thereof. Background technique [0002] In the field of industrial paint applications, solvent-based paints are mainly used for paints with mirror effects, and the appearance is uneven, which requires high spraying environment and low yield. With the continuous deepening of environmental protection awareness in various countries around the world, more and more attention has been paid to the pollution of organic solvents in automobile painting, and various countries have formulated corresponding regulations to control the VOC of automobile coatings. For the coatings industry, water-based is the main direction. [0003] Chinese patent CN103923511A provides a water-based metal coating, including component A and component B; the component A includes: 3-50g / L metal salt, 5-60g / L complexing agent, 0.1-5g / L stab...
