preparation example 1

[0075] 2.2 parts by weight of polyhexamethylene biguanide hydrochloride with a viscosity average molecular weight of 800 (Shanghai Shande Industrial Co., Ltd., PHMB) was dissolved in 5.8 parts by weight of tetrahydrofuran at 40° C. to obtain a guanidine salt solution. 2.5 parts by weight of γ-glycidoxypropyltrimethoxysilane was dissolved in 3 parts by weight of tetrahydrofuran to obtain a silane solution. Add the two solutions into the reactor for mixing, then heat the mixture to 76°C, and stir for 3 hours; after the reaction, remove the solvent in the reaction mixture under reduced pressure to obtain liquid The silane coupling agent product has a viscosity (25°C, cps) of 1665.

Abstract

The invention discloses a two-component sealant sewing agent. The two-component sealant sewing agent comprises a component A and a component B. The component A comprises, by weight, 30-100 parts of E-51 epoxy resin, 0.1-20 parts of E-44 epoxy resin, 1-50 parts of 133L epoxy resin, 1-20 parts of reactive diluents, 1-15 parts of thixotropic agents, 0.01-1 part of defoaming agents, 0-10 parts of coupling agents, 0.05-3 parts of ultraviolet absorbents, 0.001-1 part of purple blue-phase toner and 0.05-1 part of antioxidants; the component B comprises, by weight, 50-100 parts of curing agents, 0.1-20 parts of accelerators, 1-15 parts of thixotropic agents, 1-15 parts of body pigment and 3-20 parts of coupling agents. The two-component sealant sewing agent has the advantages that the prepared two-component sealant sewing agent is free of water absorption, blackening and mildew, is easy to clean and high in strength and brightness and is scrub-resistant, and oil pollution can be prevented by the two-component sealant sewing agent; the toughness of materials can be greatly enhanced, and the two-component sealant sewing agent is an environment-friendly edge sealing material with enhanced adhesive effects and the enhanced adhesive performance.

Description

technical field [0001] The invention relates to a beautifying agent and a preparation method thereof, in particular to a beautifying agent with strong adhesive force and a preparation method thereof, belonging to the field of sealants. Background technique [0002] Today ceramic tiles, mosaics and other materials have become common materials in the field of architectural decoration, and there are usually gaps between blocks and corners when laying. Traditionally, white cement and other caulking agents are used for filling. However, there are problems such as easy to change from white to black, unhygienic, and unsightly. In addition, after a period of time (for example, 1 year) after construction, microcracks and micropores are likely to form in the joints. Mold is easy to breed in the gaps, microcracks and micropores. Not only the breeding of Aspergillus niger, Aspergillus flavus and other molds will make the joints turn yellow and black, but also produce peculiar smell, w...
