Problems solved by technology

Traditional coatings will release a large amount of harmful substances such as formaldehyde and benzene, which directly endanger the health of builders and users
[0003] In addition, traditional coatings use organic solvents as the dispersion medium. The transportation and storage of coatings have high requirements, which are prone to fire and have potential safety hazards. Organic solvents are highly volatile, and long-term use will also endanger people's health. , and the use of organic solvents will increase the production cost of coatings

Abstract

The invention discloses a non-toxic and environment-friendly water-based paint and a preparation method thereof, comprising the following components in parts by weight: 100-130 parts of water-soluble resin, 80-100 parts of filler, 1-5 parts of preservative, and film-forming aid 2 to 10 parts, 2 to 8 parts of dispersant, 20 to 60 parts of deionized water; the preparation method is as follows: S1: After stirring the water-soluble resin, preservative, dispersant and deionized water evenly, add filler, disperse at high speed, Obtain the mixture; S2: Add film-forming aids to the mixture, then perform high-speed dispersion, disperse evenly and sieve to obtain the finished product. The water-based paint provided by the invention can be firmly combined with the substrate, has high gloss, good leveling, stable paint performance, good durability, and high decorative performance. Deionized water is used as a dispersant, which is green, environmentally friendly and safe. low cost.

Description

technical field [0001] The invention relates to the technical field of water-based paint preparation, in particular to a non-toxic and environment-friendly water-based paint and a preparation method thereof. Background technique [0002] With the development of various industries in the national economy, the paint industry has gradually developed from a very unobtrusive small industry to an indispensable and important industry in various fields of the national economy. Nowadays, the use of paint can be seen everywhere, such as car surface, home appliance shell, home decoration, etc., especially wall paint and furniture paint in home decoration. Traditional coatings will release a large amount of harmful substances such as formaldehyde and benzene, which directly endanger the health of builders and users. [0003] In addition, traditional coatings use organic solvents as the dispersion medium. The transportation and storage of coatings have high requirements, which are prone...
