Environment-friendly water-based paint and production process thereof

Abstract

The invention discloses an environment-friendly water-based paint and a production process thereof. The paint is prepared from the following raw materials by weight: 60-75 parts of water-based acrylicresin, 10-20 parts of sodium silicate, 4-9 parts of sorbitol, 10-20 parts of epoxypropane, 5-8 parts of a plasticizer, 2-6 parts of a preservative, 20-30 parts of a filling material, 10-16 parts of apolyurethane type dispersant, 6-12 parts of chitosan, 20-30 parts of titanium dioxide, 4-6 parts of diacetone alcohol, 30-40 parts of deionized water, 6-10 parts of a film-forming agent, 10-15 partsof ethylene glycol monobutyl ether and 5-9 parts of polysiloxane. The environment-friendly water-based paint can be improved in fame retardancy through ester formed by a reaction of sorbitol with epoxypropane; the addition of the water-soluble acrylic resin and sodium silicate can increase the adsorption capacity of the water-based paint, so falling-off of the water-soluble paint is avoided; the film formation speed of the water-based paint can be accelerated in virtue of diacetone alcohol and lithium bentonite; and chitosan can increase the antibacterial ability of the water-based paint, andthe paint is free of toxic effect on human beings and environment and has long-lasting antibacterial effect.

Description

Technical field [0001] The invention relates to the technical field of water-based paints, in particular to an environmentally-friendly water-based paint and its production process. Background technique [0002] Water-based paint is a kind of paint that uses water as a diluent and does not contain organic solvents. It has the characteristics of non-toxic, non-irritating odor, harmless to the human body and no pollution to the environment. In recent years, it has attracted widespread attention and can be used for metal and plastics. , Glass and other materials. [0003] At present, most of the domestic water-based coatings have defects such as soft coating film, non-abrasion resistance, and poor adhesion. Although in the prior art, it is usually modified by adding inorganic fillers, but the addition of inorganic fillers causes pulverization and shedding. In addition, the existing water-based paint has poor antibacterial effect and short time, which makes it easy for bacteria to gro...

Problems solved by technology

[0003] At present, most of the domestic water-based coatings have defects such as soft coating, non-wear resistance, and poor adhesion. Although in the prior art, it is usually modified by adding inorganic fillers, the addition of inorganic fillers will cause powdering and falling off. Moreover, the existing water-based paint has poor antibacterial effect and short time, which makes it easy to breed bacteria on the paint surface of hospitals, kitchens, toilets and various public places.
