Problems solved by technology

However, the functionality of traditional coatings is relatively single, and some have volatile toxic components, which endanger human health, and in order to prevent the coating film from being too thick, the hardness and scratch resistance of the surface are relatively poor. Therefore, the present invention relates to A diatomite-loaded titanium dioxide environmental protection coating, which not only has high surface hardness, good toughness, good scratch resistance, but also has good antibacterial properties

Embodiment 1

[0018] A kind of diatomite supported titanium dioxide environmental protection paint, it is made up of the following raw materials of weight part:

[0019] Tetrabutyl titanate 37, Allylthiourea 1, Sodium myristate soap 3, Trimethylolpropane 0.6, 2-Mercaptobenzimidazole 1, Ethylenediamine 3, Lauryl alcohol ester 2, Diatomaceous earth 20, styrene 30, ammonium persulfate 0.8, styrene-acrylic emulsion 200, sorbitan monooleate 2.

[0020] A preparation method of diatomite-supported titanium dioxide environmental protection paint, comprising the following steps:

[0021] (1) Take 2-mercaptobenzimidazole, add it to 30 times its weight in absolute ethanol, stir evenly, add trimethylolpropane, raise the temperature to 50°C, keep it warm for later use, and record it as propanol solution ;

[0022] (2) Take diatomite, calcinate at 800°C for 1 hour, cool to room temperature, grind into fine powder, add it to ethylene glycol solution 3 times its weight, stir and react for 15 minutes, and...

Abstract

Diatomite-loaded titanium dioxide environment-friendly coating is disclosed. The coating includes, by weight, 37-40 parts of tetrabutyl titanate, 1-2 parts of allylthiourea, 3-5 parts of sodium myrastate, 0.6-1 part of trimethylolpropane, 1-2 parts of 2-mercaptobenzimidazole, 3-4 parts of ethylenediamine, 2-3 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 20-30 parts of diatomite, 21-30 parts of styrene, 0.8-1 part of an initiator, 170-200 parts of styrene-acrylic emulsion and 2-4 parts of sorbitan monooleate. The coating has good surface toughness, high bacteriostatic capability, high toxic and harmful gas adsorption capacity, good scratch resistance and excellent comprehensive performance.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a diatomite-loaded titanium dioxide environmental protection coating and a preparation method thereof. Background technique [0002] The exterior wall decoration is directly exposed to nature and is subjected to wind, rain, and sun exposure. Therefore, the coating is required to have water resistance, color retention, pollution resistance, aging resistance, and good adhesion. It also has good freeze-thaw resistance and film-forming properties. The characteristics of low temperature. Exterior wall coatings are divided into four categories according to decorative texture: 1. Thin exterior wall coatings: fine texture, less materials used, can also be used for interior wall decoration, including flat coatings, sand wall-like, mica-like coatings. 2. Multi-layer pattern paint: the pattern is concave and convex, full of three-dimensional effect. 3. Colored sand coating: dyed quart...
