Embodiment 1

[0008] Weigh 30g of titanium dioxide, 8g of superfine heavy calcium, dilute with 19.6g of clean water, add 0.5g of ethylene glycol and 0.5g of 1288 polyacrylic acid sodium salt dispersant, carry out high-speed dispersion stirring and grinding, put the ground materials back into the mixer in order Sequentially add 40g pure acrylic emulsion, 1g2,2,4-trimethyl-1,3-pentanediol monoisobutyrate film-forming aid and pre-dispersed 4g nano-silica antibacterial agent, 0.2g sodium polyacrylate Stir the thickener, 0.2g polyethylene glycol type defoamer, etc. evenly, and pay attention to constantly adjust the pH value to 9-10 during the stirring process. After being uniformly dispersed, the product is obtained, and can be measured, packaged, discharged, and stored.

Embodiment 2

[0010] The raw materials weighed according to the weight ratio are: 32g of titanium dioxide, 8g of superfine heavy calcium, 11.4g of purified water, 0.5g of ethylene glycol, 0.5g of 1288 polyacrylic acid sodium salt dispersant, 42g of pure acrylic emulsion, 1g2,2,4- Trimethyl-1,3-pentanediol monoisobutyrate, polyethylene glycol type defoamer 0.2g, the process steps are the same as in Example 1.

[0011] See accompanying drawing 1 for other embodiments.

[0012] The invention is novel in concept and can effectively solve the problems of traditional interior wall coatings such as being susceptible to moisture and easily multiplying bacteria and mold, as well as overcoming the unpleasant smell, short drug effect and difficult operation caused by using physical or chemical methods to disinfect the surface of the interior wall. Convenience, physical method one-time investment is big etc. deficiency, is conducive to the protection of environment and people's disease prevention and h...

Abstract

A nano-class antibacterial paint is prepared from environment protection type water-soluble acrylic paint titanium oxide powder and nano-class antibacterial silicon oxide. Its advantages are high effect and durability, high compactness, and high adhesion.

Description

Technical field [0001] The invention relates to a formula and a production process of a nanometer antibacterial paint. Background technique [0002] Paint is the most convenient, most economical and most widely used method among various finishing methods. However, with the development of industry and the deterioration of the environment, it often causes mildew and growth of germs on the surface of the interior wall. For example, the walls of food and beverage production workshops are rich in nutrients and suitable for temperature and humidity, so it is easy to breed bacteria and molds, thereby contaminating food and harming people; there are also high-temperature and high-humidity living rooms in the south, and the walls are also prone to breeding molds. It affects the appearance and is harmful to health; especially in hospitals and kindergartens, if they are not disinfected frequently, it is very easy to cause contact infection of personnel due to the bacteria on the walls...
