Contamination-resistant antibacterial cement-based ceramic tile joint mixture preparation method

Abstract

The invention relates to a contamination-resistant antibacterial cement-based ceramic tile joint mixture preparation method and belongs to the technical field of decoration material preparation. According to the preparation method disclosed by the invention, biomass soybean containing rich protein and squid tentacles are utilized as raw materials, the raw materials go mouldy under the high temperature and high humidity conditions, mould grows out, standing and fermentation are performance on the mould, microorganisms are utilized to degrade biomass protein into micromolecular polypeptide and amino acid at first, then the polypeptide and the amino acid are further degraded, hydration of a mixed system is promoted, and a lot of short-prismatic ettringite is generated through chemical reaction; thus, the amount of calcium hydroxide in a joint mixture is reduced, and contamination resistance of the joint mixture is improved. According to the preparation method disclosed by the invention, apart of metal ions in silicate minerals can be dissolved out and removed by acidic matter in fermentation filtrate and active groups with complexing performance in a mixed fermentation process of thefermentation filtrate, montnorillonoid, attapulgite and gypsum powder; the microorganisms can be oxidized and degraded by the silicate minerals; thus, antibacterial performance of the ceramic tile joint mixture disclosed by the invention is improved, and the ceramic tile joint mixture has a wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of a stain-resistant and antibacterial cement-based ceramic tile joint filler, which belongs to the technical field of preparation of decorative materials. Background technique [0002] Tile grout is used for gap decoration of ceramic tiles, mosaics, stone, wood, glass, aluminum-plastic panels and other materials. Tile grout is often used for tile coverings in bathrooms and floors. With the development of society, tiles have become one of the most commonly used materials in architectural decoration. At present, the most commonly used filling material for the gap between tiles is cement-based tile grout. This type of cement-based tile grout has been used for a period of time and the surface is very dirty, which affects the aesthetic effect. [0003] In modern buildings, tiles have become the main building materials and are widely used in the decoration of the interior and exterior walls and floors of buil...

AI Technical Summary

Problems solved by technology

[0006] The technical problem mainly solved by the present invention is that the surface compactness of the current cement-based tile joint sealant is poor, there are many micropores, and a lot of dust and dirt will accumulate for a long time, and the poor stain resistance will affect the appearance of the joint sealant, and The caulking agent will breed a large number of bacteria and molds in a humid environment for a long time, which will cause harm to the human body. A method for preparing a stain-resistant and antibacterial cement-based tile grouting agent is provided.
