Abstract

The invention provides a construction adhesive and a preparation method thereof. The adhesive is composed of the following raw materials in percentages by mass: 40-60% of polyvinyl alcohol, 5-20% of epoxy resin, 5-10% of hydroxymethyl cellulose, 4-12% of vinyl acetate, 5-10% of polyacrylamide, 1-2% of potassium persulfate, 0.5-1% of N,N-dimethylbenzylamine, 3-5% of an alkaline liquid, 0.5-1% of asurfactant, 0.5-1% of a modifier, and the balance water. The adhesive provided by the invention has high-strength tensile properties, does not contain an aldehyde compound, and has high safety and environmental protection performance.

Description

technical field [0001] The invention belongs to the technical field of construction adhesives, and in particular relates to a construction adhesive and a preparation method thereof. Background technique [0002] In the process of construction, tiles or (and) floor tiles are often used for aesthetics, and adhesives are often used in the process of processing. Adhesives suitable for the construction industry usually have the following characteristics: 1. High tensile strength; 2. Can be used for a long time at minus 40 to 80 degrees Celsius; 3. Excellent moisture and heat aging resistance and water resistance; 4. Easy to operate, moderate curing speed. [0003] However, the tensile strength of the traditional construction adhesives currently used cannot meet the needs, and most of them contain aldehyde harmful substances, which have a great impact on the living environment and human health. With the enhancement of people's health awareness, more and more attention has been p...
