A two-component antibacterial and antifouling epoxy beautifying agent and its preparation method

Abstract

The invention discloses a two-component antibacterial and antifouling epoxy beautiful sealant and a preparation method thereof. The epoxy beautiful sealant comprises a component A and a component B according-a mass ratio of 1:(0.8-1.2), wherein the component A comprises, by mass, 65-80 parts of epoxy resin, 10-20 parts of an antibacterial and antifouling assistant, 1-5 parts of a thixotropic agent, 0.1-0.5 part of an antifoaming agent and 0.1-0.5 part of a leveling agent; and the component B comprise, by mass, 20-35 parts of epoxy resin, 35-50 parts of an epoxy resin curing agent, 5-20 parts of a pigment, 1-5 parts of the thixotropic agent, 0.1-0.5 part of the antifoaming agent and 0.1-0.5 part of the leveling agent. The preparation method is simple, and is characterized in that materialsare mixed to obtain the component A and the component B, and the component A and the component B are uniformly mixed when used. The epoxy beautiful sealant has the advantages of high strength, low shrinkage rate, strong adhesiveness, high brightness, good aesthetic effect, long-lasting antibacterial and antifungal effect, good hydrophobic and oleophobic property, easiness in cleaning, simplicity and convenience in construction, environmental protection and no pollution.

Description

technical field [0001] The invention relates to a two-component antibacterial and antifouling epoxy beautifying agent and a preparation method thereof. Background technique [0002] Ceramic tiles are a widely used decoration material. Usually, after the tiles are laid, white cement needs to be used to fill the gaps between the tiles. Although it can achieve beautiful and anti-fouling effects, its surface is rough, dull, and prone to mildew Blackened and difficult to clean. In recent years, a new type of caulking material—beautiful caulking agent has appeared on the market.
