Problems solved by technology

The molecule of polyvinyl alcohol contains a large number of hydroxyl functional groups, it forms a particularly delicate film, has poor air permeability, and easily absorbs water
resulting in a coating that is not waterproof
From ancient times to the present, both the raw material formula of the paint and the process of the ingredients have been improved countless times, but they are still unsatisfactory. At least there are the following disadvantages: 1. Because the traditional paint contains polyvinyl alcohol, the gloss of the paint is poor and Heat resistance is not high
2. Generally, water-based paint is difficult to polish and apply, easy to crack and peel off, and has a short service life
3. Consume the country's precious energy and pollute the environment
4. Contain heavy metal elements, cause indoor air pollution, and cause great harm to human body during processing

Abstract

The invention discloses an environment-friendly waterborne coating for buildings and a preparation method of the environment-friendly waterborne coating. The environment-friendly waterborne coating is prepared from 25-35 parts of a water-soluble acrylate polymer, 20-30 parts of light calcium carbonate, 18-25 parts of talcum powder, 10-15 parts of sodium silicate, 15-20 parts of heavy calcium carbonate powder, 10-15 parts of titanium dioxide, 15-25 parts of emulsified epoxy resin, 2-4 parts of a plasticizer, 5-8 parts of auxiliaries, 3-6 parts of a curing agent, 4-6 parts of a defoaming agent, 2-5 parts of a leveling agent and 15-25 parts of water. The obtained waterborne coating is non-toxic, pollution-free and environment-friendly; the adhesive force is 0-level, and the environment-friendly waterborne coating is not prone to falling off, is high in corrosion resistance and shock strength and has good covering power and good comprehensive performance; the production technology is simple, the use range is wide, the cost is low, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of architectural paint production, in particular to an environment-friendly architectural water-based paint and a preparation method thereof. Background technique [0002] Powder coating is a new type of solvent-free, 100% solids powder coating. It has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. It has two categories: thermoplastic powder coating and thermosetting powder coating. Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers, plasticizers and stabilizers. Thermoplastic powder coatings include: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, polyester. Thermosetting powder coatings are composed of thermosetting resins, curing agents, pigments, fillers and additives. Thermosetting powder coatings inclu...
