Water-based acrylic finish paint

Abstract

The invention provides water-based acrylic finish paint. The water-based acrylic finish paint comprises, by weight, 24.0-31.0 parts of water-based acrylic acid, 0.4-1.1 parts of dry mixtures, 21.0-30.0 parts of deionized water, 2.2-3.4 parts of ethylene glycol butyl ether, 0.1-0.5 part of dispersing agents, 0.1-0.4 part of defoaming agents, 1.2-3.7 parts of titanium dioxide, 6.0-13.0 parts of 2% EW bentonite pre-adhesive, 2.1-5.4 parts of attapulgite, 2.3-8.8 parts of light chrome yellow, 3.7-9.5 parts of medium chrome yellow, 0.6-3.4 parts of iron oxide yellow, 1.5-3.4 parts of pH (potentialof hydrogen) regulators, 2.27-5.64 parts of coalescing agents, 0.05-0.3 part of base material wetting agents, 0.14-0.3 part of leveling agents, 0.4-0.9 part of flash rust inhibitors, 0.3-0.9 part of thickeners and other 2.0-8.0 parts of deionized water. The water-based acrylic finish paint has the advantages of excellent anti-settling performance, corrosion resistance, weather resistance and scratch resistance.

Description

technical field [0001] The invention relates to the field of paints, in particular to a water-based acrylic topcoat. Background technique [0002] Water-based resin is a new field of polymer science, which began to be studied abroad in the 1970s. Due to the advantages of environmental friendliness, safety and easy availability, convenient construction, and wide coverage, some products have been gradually industrialized. Water-based resin is a new type of resin system that uses water instead of organic solvents as the dispersion medium. The polymer resin is dispersed in water, and the viscosity suitable for processing can be adjusted arbitrarily to form a metastable liquid. After the water in the system volatilizes, it forms a resin bonding material. The focus of water-based resin research is to obtain film-forming materials with excellent physical properties after water volatilization, to achieve "water-based resin water insoluble", and to overcome factors that are not condu...

AI Technical Summary

Problems solved by technology

Second, due to the difficulty in development, the current water-based paint preparation process is costly and inefficient, so the price of the mainstream water-based paint in the market is relatively high, so it has not been widely used

Third, due to the immature development of water-based coatings, most companies and individuals are not willing to take the risk of using new water-based coatings to replace the old solvent-based coatings due to safety considerations.

Compared with solvent-based coatings, water-based coatings are more difficult to develop, the preparation process costs more, and the performance is not necessarily better than solvent-based coatings

Generally, water-based coatings have slow drying speed, low toughness, hardness, water resistance, and wear resistance are not good enough
