Problems solved by technology

[0003] In the existing technology, when the waterproof coating is exposed to a humid environment for a long time, various molds and other microorganisms are easy to grow on the surface, and these molds will enter the pores of the cement, Destroy the film-forming substance, reduce its waterproof performance, or even lose its impervious and waterproof performance

Embodiment 1

[0039] A kind of antibacterial and mildew proof waterproof coating described in the embodiment of the present invention, the coating composition is as follows:

[0040]

[0041] When working, the elastic emulsion is a copolymer of acrylate and silicone. The elastic emulsion has excellent resilience, flexibility, adhesion, water resistance, weather resistance, dust resistance and UV resistance; it can effectively cover The fine cracks on the wall have a good beautification and protection effect on the wall; dithiocarbamate can mainly play a role in anti-mildew, and benzisothiazolinone can play a role in sterilization, thereby ensuring the antibacterial effect of the coating. Anti-mildew and waterproof properties.

[0042] like figure 1 As shown, a preparation process of an antibacterial, mildew-proof and waterproof coating, the preparation process is suitable for the preparation of the above-mentioned coating, and the preparation process is as follows:

[0043] S1: first p...

Embodiment 2

[0054]like Figure 10 As shown in the comparison example 1, another embodiment of the present invention is: a set of inclined grooves 6 are formed on the outer side wall of the tapered block 34; Column 61; during operation, when the cone block 34 is rotated, the telescopic column 61 will be pushed outward under the action of centrifugal force, thereby increasing the crushing area of ​​the cone block 34. At the same time, when it is not rotated or reversed, the When the telescopic column 61 enters the inclined groove 6, the outer side wall of the telescopic rod is cleaned by using the opening wall of the inclined groove 6 to prevent powder from adhering to the telescopic rod.

[0055] Working principle: In the prior art, when the solid powder material is unloaded, it is often directly poured into the solution, which is easy to cause the solid powder to agglomerate into a group and affect the subsequent mixing uniformity. When the present invention is working, when the material...

Abstract

The invention belongs to the technical field of building coatings, and particularly relates to an antibacterial mildewproof waterproof coating and a preparation process thereof.The preparation process includes the steps that S1, deionized water, elastic emulsion and waterborne polyurethane are put into a box through a liquid inlet pipe, then a motor is started, the motor drives a first rotating shaft to rotate and drives a stirring rod to rotate, and the stirring time is 10-15 min; s2, then titanium dioxide, modified styrene-acrylic latex powder, VAE rubber powder and modified diatomite enter a box body through a powder inlet pipe, when a motor drives a first rotating shaft, a second rotating shaft can drive a discharging plate to rotate and uniformly discharge, and the stirring time is 30-40 min; the invention aims to solve the problems that when a waterproof coating is exposed in a humid environment for a long time, various microorganisms such as mould are easy to breed on the surface of the waterproof coating, and the mould can enter pores of cement to destroy film-forming substances, so that the waterproof performance of the waterproof coating is reduced and even the impermeability and waterproof performance of the waterproof coating are lost.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, in particular to an antibacterial, mildew-proof and waterproof coating and a preparation process thereof. Background technique [0002] The waterproof coating has the effect of impermeability and waterproofing, and can be coated on the surface of the building to avoid moisture damage to the basic structure of the building in some wet environments such as toilets, underground passages or reservoirs, which can effectively protect the building and prolong its life. service life. [0003] In the prior art, when the waterproof coating is exposed to a humid environment for a long time, the surface of the waterproof coating is prone to breed various microorganisms such as molds. Waterproof performance. [0004] To this end, the present invention provides an antibacterial, mildew-proof and waterproof coating and a preparation process thereof. SUMMARY OF THE INVENTION [0005] In order...
