Problems solved by technology

At present, there are three kinds of antibacterial agents used in coatings: organic antibacterial agents; photocatalytic antibacterial agents, such as titanium dioxide, zinc oxide, etc.; Antibacterial agents have good antibacterial properties only under certain conditions of ultraviolet light, oxygen, and water, so they are not suitable for indoor applications; existing antibacterial wood lacquers cannot meet the requirements of antibacterial and environmental protection

preparation example Construction

[0019] The preparation method of high-performance nano-silver water-based wood lacquer in the embodiment is: take each raw material according to weight part; Potassium, ethylene glycol monoethyl ether, lauryl alcohol ester, and defoamer are put into the stirrer, and stirred at a rotating speed of 800r / min for 10min to obtain a high-performance nano-silver water-based wood varnish.

[0020] Silicone-modified acrylic emulsion is an emulsion polymer of organosilicon compound and acrylate. The particle size distribution of the emulsion is uniform, the stability of the emulsion is high, the comprehensive performance of the coating film is good, the waterproof performance is good, and the waterproof performance can reach a higher level; Dropping method, 50g of methyl methacrylate, n-butyl acrylate, acrylic acid mixed monomer and initiator were added dropwise into 100g of silicone emulsion to synthesize silicone-modified acrylic emulsion;

[0021] The water-based high-performance pur...

Abstract

The invention provides high-performance nano-silver water-borne wood paint, which relates to the technical field of coatings. The high-performance nano-silver water-borne wood paint is prepared from the following raw materials: a nano-silver antibacterial agent, carbon nano tube dispersion liquid, a water dispersible modified acrylic emulsion, filler, butyl acrylate, potassium peroxodisulfate, ethylene glycol monoethyl ether, dodecanol ether, and a defoaming agent. The high-performance nano-silver water-borne wood paint provided by the invention has a high-effect broad-spectrum bactericidal function and an excellent film-forming property, has a high adhesive force on wood materials, is not easy to fall off so as not to easily harm a human body, and can well remove hazardous substances suchas benzene, ammonia, and VOC (Volatile Organic Compounds) free in air; a microcellular structure and a high specific surface area of a carbon nano tube have a certain physisorption function on hazardous substances such as formaldehyde in indoor air, so that the indoor air is purified to a certain degree.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a high-performance nano-silver water-based wood paint. Background technique [0002] Traditional civil wood paints such as polyurethane paint and nitro paint are the mainstream products of wood paint because of their cheap price and convenient construction. However, these traditional wood paints will release a large amount of toxic and harmful solvents during and after painting. Free TDI, some also contain heavy metals, do not meet environmental protection requirements. With the development of society, people's awareness of green environmental protection is enhanced, and the country's advocacy and pressure on green environmental protection policies have brought opportunities for the development of water-dispersible water-based paints and other green environmental protection coatings. Although traditional oil-based paints still account for a relatively large market share, water-...
