Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of the single-component beautifying agent in the prior art, such as poor adhesion, no stain resistance, no resistance to scrubbing, and easy to mold and blacken in a humid environment, while the two-component beautifying agent The curing agent is highly volatile and toxic at room temperature, and the cured product is brittle, with poor toughness and impact strength, which leads to easy cracking after beautification and affects the effect of beautification. A two-component anti-cracking beautification agent is provided and its preparation method, the epoxy resin is used as the base material in the A component, and the polyamide surface-modified nano-titanium dioxide is used as the curing agent and the filler in the B component, and the prepared two-component beautifying agent has good adhesion , anti-fouling, anti-mildew, scrub resistance, high hardness, low toxicity and good impact strength, not easy to crack

Abstract

The invention relates to the field of coatings, and discloses a two-component anti-crack beautifying agent and a preparation method thereof. The beautifying agent is made by mixing component A and component B according to the mass ratio of 1: (0.5~2), with In parts by weight, component A includes: 40-70 parts of epoxy resin, 0.1-10 parts of fluorocarbon resin, 2-15 parts of emulsifier, 5-20 parts of diluent, 5-50 parts of pigment and filler, 0.1-5 parts of pH regulator, 0.1~5 parts of wetting and dispersing agent, 0.01~2 parts of defoamer, 5~50 parts of deionized water; component B includes 15~30 parts of nano-titanium dioxide modified by polyamide surface, diluent 10~ 40 parts, 0.01~5 parts thickener, 1~10 parts pigments and fillers. The invention uses polyamide surface-modified nano-titanium dioxide as a curing agent and a filler at the same time, and the prepared beautifying agent has good adhesion, anti-fouling, anti-mildew, scrub resistance, high hardness, low toxicity and good impact strength. Not easy to crack.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a two-component anti-cracking beautifying agent and a preparation method thereof. Background technique [0002] With the development of building decoration materials, the application of ceramic tiles, stone materials, mosaics, wood lines and other materials is becoming more and more common. A large number of gaps are produced when materials are spliced, which makes the application of beauty joints more and more extensive. At present, the commonly used beautifying agents include one-component polymer emulsion type beautifying agent and oily two-component epoxy beautifying agent. Disadvantages such as scrub resistance, easy to mold and black in humid environment. [0003] At present, amine curing agents are generally used in the two-component epoxy beautifying agent, for example, "a kind of water-based epoxy resin beautifying agent and its preparation method and application" disclosed in ...
