Sealant with high hardness and ceramic-like texture and preparation method thereof

Abstract

The invention discloses a high-polymerization-degree high-strength high-hardness sealant and a preparation method thereof. The sealant comprises a component A and a component B. The component A comprises, by weight, 70-100 parts of E-51 epoxy resin, 1-20 parts of propylene glycol methyl ether acetate and 1-10 parts of fumed silica. The component B is prepared from the following raw materials in parts by weight: 20 to 40 parts of 1.3 BAC (1,3-cyclohexane dimethylamine), 20 to 40 parts of propylene glycol methyl ether acetate, 10 to 30 parts of E-51 epoxy resin, 1 to 20 parts of fumed silica and 1 to 20 parts of pearl powder. After the sealant prepared by the method is completely cured, the hardness can reach more than 80D and is close to the hardness of a ceramic tile, and the sealant has the characteristics of smooth ceramic surface, easiness in cleaning and dirt resistance.

Description

technical field [0001] The invention relates to the technical field of caulking agents, in particular to a beautifying caulking agent with high hardness and ceramic-like texture and a preparation method thereof. Background technique [0002] With the development of society, people pay more and more attention to the dirty, moldy and unhygienic phenomenon of tile gaps, and the requirements for the use of beautifying grout products are also increasing. [0003] Conventionally, cement, putty powder and other materials are used to fill the gaps between tiles. Due to the low hardness and low density of the cured product, the surface is not smooth, and it is easy to hide dirt after a long time, causing mildew, blackening, and odor, and the surface is uneven. Cleaning, thereby affecting the home environment. [0004] Although improved one-component acrylic beautifying agents and ordinary low-polymer flexible epoxy beautifying agents also appeared on the market in the later period, ...

AI Technical Summary

Problems solved by technology

[0003] Cement, putty powder and other materials are generally used to fill the gaps between tiles. Due to the low hardness and low density of the cured product, the surface is not smooth, and it is easy to hide dirt after a long time, causing mildew, blackening, and peculiar smell, and the surface is uneven. Cleaning, which in turn affects the home environment

[0004] Although improved one-component acrylic beautifying agents and ordinary low-polymer flexible epoxy beautifying agents also appeared on the market in the later period, most of these beautifying agents have low hardness, low density, rough surface, difficult to clean, and are not resistant to dirt. And other issues
