Problems solved by technology

[0003] The grouting agent is filled in the gaps of tiles, which requires a certain toughness to adapt to the thermal expansion and contraction of tiles caused by temperature changes in different seasons. Due to the poor toughness of epoxy resin itself, the current method is to make the curing agent over 50%. above, thereby reducing the crosslinking density and improving toughness. Obviously, this causes a waste of raw materials
[0004] When the beautifying agent is used in the humid climate in southern China or in the humid environment such as the bathroom, it is easy to breed mold and endanger human health. At present, there are many kinds of bactericidal and antifungal agents that can inhibit the growth of mold. When added to polymer materials, there are easy Migration overflow problem

Abstract

The invention belongs to the technical field of bifunctional epoxy resin modifiers and particularly relates to an epoxidized soybean oil-based anti-mildew agent and a preparation method and application thereof, and epoxidized decorative tile grout; the epoxidized soybean oil-based anti-mildew agent is made by subjecting epoxidized soybean oil and hydroxyl-bearing disinfecting anti-mildew agent tochemical reaction, wherein the molar ratio of epoxy groups in the epoxidized soybean oil to the hydroxyl-bearing disinfecting anti-mildew agent is 1:(0.10-0.80); the reaction system also includes an alkaline catalyst, wherein the weight ratio of the epoxidized soybean oil to the alkaline catalyst is 1:(0.005-0.10). The epoxidized soybean oil-based anti-mildew agent prepared herein has improved transfer resistance, provides improved toughening effect for epoxy resin materials, and provides improved thermal impact performance and anti-mildew property for decorative tile grouts.

Description

technical field [0001] The invention belongs to the technical field of preparation of bifunctional epoxy resin modifiers, and in particular relates to an epoxy soybean oil-based antifungal agent, a preparation method and application thereof, and an epoxy beautifying agent. Background technique [0002] Tile beautifying agent is mainly composed of epoxy resin and pigments and fillers. It is used to beautify the gaps of ceramic tiles, mosaics, stones, etc. It is easy to operate and easy to construct. It does not contain toxic and volatile substances such as toluene and xylene, and the surface is smooth after curing. , Easy to scrub, and waterproof and moisture-proof, it is widely used in the fields of home decoration, hotels and other floor and wall decoration. [0003] The grouting agent is filled in the gaps of tiles, which requires a certain toughness to adapt to the thermal expansion and contraction of tiles caused by temperature changes in different seasons. Due to the po...
