Problems solved by technology

[0002] At present, traditional latex paint products mostly use titanium dioxide and inorganic fillers to provide hiding power and product performance, but because of its high price, titanium dioxide leads to high product costs and limited usage; traditional inorganic fillers are used in surface modification and inorganic-organic compounding. Due to lack of technology, it is difficult to improve the contrast ratio, weather resistance, stability, production efficiency and many other negative properties of coating products

Embodiment 1

[0022] A kind of antibacterial latex paint, its raw material component and weight are:

[0023]

[0024] The balance is water.

[0025] In the present embodiment, the heavy calcium is 800 mesh heavy calcium powder.

[0026] In this embodiment, the thickener is a polyurethane thickener.

[0027] A preparation method for antibacterial latex paint, the method may further comprise the steps:

[0028] (1) Put deionized water and 1 / 2 of the defoamer into the dispersion tank, turn on the stirring device, and control the rotation speed to 600r / m;

[0029] (2) Put multi-element titanium dioxide additives, styrene-acrylic emulsion and heavy calcium into the mixed solution of deionized water and 1 / 2 defoamer that is stirred evenly, control the rotation speed of the stirring device at 1200rpm, and disperse at a high speed for 15min;

[0030] (3) After high-speed dispersion, sand-mill and filter the mixture to control the fineness of the sample to be less than 50um, and finally add t...

Abstract

The invention relates to an anti-bacterial emulsion paint. The paint comprise following ingredients, by weight: 0 to 15% of a multi-element titanium white auxiliary agent, 40 to 50% of ground calcium carbonate, 20 to 30% of styrene acrylic emulsion, 0.3% of an antifoaming agent, 0.4% of a thickening agent, and the balance being water. The paint comprises a plurality of raw materials containing no gas which is harmful and volatilizable. Preparation method is simple. The paint is green and friendly to environment, does no harm for human, and processes high water and corrosion resistances, and excellent application properties.

Description

technical field [0001] The invention belongs to the field of latex paint, in particular to an antibacterial latex paint and a preparation method thereof. Background technique [0002] At present, traditional latex paint products mostly use titanium dioxide and inorganic fillers to provide hiding power and product performance, but because of its high price, titanium dioxide leads to high product costs and limited usage; traditional inorganic fillers are used in surface modification and inorganic-organic compounding. The lack of technology makes it difficult to improve the contrast ratio, weather resistance, stability, production efficiency and many other negative properties of coating products. [0003] At the same time, people's pursuit of a healthy and clean ecological living environment is becoming more and more intense, and people are paying more and more attention to products with antibacterial functions. Antibacterial latex paint not only has fine and plump coating, wa...
