Example Embodiment

[0017] Table 1 The weight ratio of embodiment 1~embodiment 3

[0018]

[0019] In the above embodiments, the vinyl alcohol is industrial grade 1799; the molecular weight of the epoxy resin is 8000-200000, the epoxy value is 0.48-0.54; the molecular weight of the polyamide is 2000-12000; the molecular weight of the polyacrylamide is 50000-120000 ; The initiator is a mixture of ammonium persulfate and sodium sulfite, and the molar ratio is 1:1; the particle size range of bentonite is 5-500 microns; the surfactant is sodium dodecyl sulfonate.

[0020] The preparation method of each embodiment is:

[0021] S1, add polyvinyl alcohol, surfactant and part of deionized water in the reaction kettle, stir and heat up to about 70~80°C, so that the polyvinyl alcohol is completely dissolved;

[0022] S2 combines epoxy resin, epoxy acrylate, polyamide, polyacrylamide, nonylphenol polyoxyethylene ether, ethylene-vinyl acetate emulsion, initiator, octyltrimethoxysilane, γ-methacryloyl Ox...

Abstract

The invention provides a high-performance building adhesive which comprises the following materials by weight: 20-80 parts of polyvinyl alcohol, 5-20 parts of epoxy resin, 0.1-2 parts of polyamide, 4-12 parts of polyacrylamide, 6-12 parts of epoxy diacrylate, 1-5 parts of nonylphenol polyoxyethylene ether, 20-60 parts of ethylene-vinyl acetate emulsion, 0.1-3 parts of initiator, 1-5 parts of octyltrimethoxysilane, 2-4 parts of gamma-methacryloxypropyltrimethoxysilane, 5-10 parts of hydroquinone, 5-10 parts of gypsum powder, 1-5 parts of bentonite, and 400-800 parts of deionized water. The building adhesive has good adhesion performance, high bonding strength, high drying speed, good waterproof performance, mildew resistance, no toxicity and harm, and no environment pollution. Compared with conventional building adhesive, the high-performance building adhesive has good bonding performance, stripping strength above 12 MPa, and tensile shearing strength above 20 MPa.

Description

technical field [0001] The invention provides a high-performance construction adhesive and belongs to the technical field of adhesives. Background technique [0002] With the development of society and the improvement of living standards, the demand for construction adhesives in the construction and decoration industries is increasing day by day. The adhesive strength, waterproof and other indicators of the traditional construction adhesives currently used cannot meet the needs, and most of them contain a large amount of harmful substances such as aldehydes and organic solvents, which have a great impact on the living environment and human health. With the enhancement of people's health awareness, more and more attention is paid to indoor decoration and environment, traditional construction adhesives are gradually eliminated, and high-performance, environmentally friendly construction adhesives are attracting more and more attention and have great market demand.
