Problems solved by technology

[0003] At present, most of the water-based paints used in the market have a long drying time during film formation, and the elasticity of the paint film is easy to age, and the hardness is not good, which cannot effectively protect the strength of the bottom layer of the wall, resulting in cracking and falling off of the wall surface, which not only affects the building It is beautiful, and the wall is cracked, which leads to problems such as water leakage on the wall. At the same time, water-soluble coatings are susceptible to biological damage. Since the production of bacteria depends on the environment with water, most of the existing water-soluble coatings are prone to mildew. causing a lot of inconvenience

Among them, the fireproofing agent is made by mixing expanded vermiculite, glass beads, diatomite, and fine asbestos in the weight ratio of 2:4:1:2; the antibacterial agent is made by mixing the natural antibacterial agent and inorganic antibacterial agent in the weight ratio of 1:3. The natural antibacterial agent is a mixture of bamboo leaf extract, ginkgo biloba extract, and pomegranate peel extract in a weight ratio of 1:1:1; the inorganic antibacterial agent is silver-type zeolite antibacterial agent. The components of natural antibacterial agents and inorganic antibacterial agents can be purchased from the market.

Embodiment 3

[0025] A water-based paint, consisting of the following components by weight: 30 parts of water, 20 parts of acrylic emulsion, 0.5 parts of wetting agent, 0.3 parts of defoamer, 15 parts of titanium dioxide, 15 parts of talcum powder, 0.3 parts of fireproofing agent, 0.4 part of antibacterial agent. Among them, the fireproofing agent is a mixture of expanded vermiculite, glass beads, diatomite, and fine asbestos in a weight ratio of 3:4:2:1; the antibacterial agent is a mixture of a natural antibacterial agent and an inorganic antibacterial agent in a weight ratio of 1:3. The natural antibacterial agent is a mixture of bamboo leaf extract, ginkgo biloba extract, and pomegranate peel extract in a weight ratio of 1:1:1; the inorganic antibacterial agent is silver-type zeolite antibacterial agent. The components of natural antibacterial agents and inorganic antibacterial agents can be purchased from the market.

Abstract

The invention discloses a water-based coating which is characterized by comprising the following components by weight parts: 20-30 parts of water, 20-25 parts of an acrylic emulsion, 0.3-0.5 part of a wetting agent, 0.1-0.3 part of a de-foaming agent, 15-20 parts of titanium dioxide, 10-15 parts of talcum powder, 0.3-0.5 part of a fireproof agent and 0.2-0.4 part of an antibacterial agent. The coating disclosed by the invention is reasonable in composition, low in cost, good in compatibility among the components, environment-friendly, mildew-proof and flame-retardant, and has excellent application values; a natural antibacterial agent and an inorganic antibacterial agent are mixed for use, so that the problems of poor stability due to single use of the natural antibacterial agent or pollution caused by single use of an organic antibacterial agent and high cost due to single use of the inorganic antibacterial agent are solved; due to combined use, the mildew-proof effect is more lasting; the film-forming drying time is short, the hardness is good, and the extensibility and the heat resistance are good.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based coating. Background technique [0002] Water-based coatings are coatings that use water as a dispersion medium and thinner. Compared with organic solvent-based coatings, water-based coatings save a lot of organic material resources, greatly reducing the pollution of the atmosphere caused by the volatilization of organic solvents in coatings and the pollution during construction. Fire hazard. Water is an extremely abundant resource on the earth. It is easy to use and low in cost. When used as a solvent in paint, it will not cause damage to water resources or less. Therefore, the water-based coating not only reduces the emission of volatile organic solvents, but also saves resources and energy, and is convenient for transportation and storage. With the enhancement of people's awareness of environmental protection, the use of water-based coatings is incre...
