Problems solved by technology

The vinyl acetate used in this glue is highly toxic and not environmentally friendly
[0005] Chinese invention patent application 201410004735.1 (public date: April 16, 2014) discloses an environmentally friendly white latex, the glue includes: polyvinyl alcohol PVA, vinyl acetate VAC, acrylic acid AA, acrylamide AM, persulfuric acid Ammonium, anionic emulsifier A-102, alkyl polyoxyethylene ether LCN-287 nonionic emulsifier; corn starch, transparent powder, plasticizer, diethylene glycol dibenzoate DEDB, preservative KSG-201, hydrogen Sodium oxide, and methanol; but this glue still uses toxic vinyl acetate, which has poor environmental performance
[0006] At the same time, the related glue disclosed in the prior art has poor overall performance in terms of use effect, and cannot yet meet the relevant requirements for the quality of high-grade energy-saving wooden doors and windows.

Abstract

The invention provides a powerful adhesive. The powerful adhesive comprises the following components in parts by weight: 900 parts of polyvinyl acetate, 330 parts of vinyl acetate, 130 parts of polyvinyl alcohol, 85 parts of dibutyl phthalate, 30 parts of diethylene glycol dibenzoate, 13 parts of octyl alcohol, 37 parts of isopropyl alcohol, 19 parts of allyl methacrylate, 8 parts of glycol dimethacrylate, 5 parts of toluene diisocyanate, 41 parts of sodium bicarbonate, 1460 parts of water, 37 parts of a compound emulgator, 6 parts of a compound initiator, 27 parts of hydroxymethyl acrylamide, 13 parts of waxy corn starch and 5 parts of sodium hypochlorite. According to the powerful adhesive, the content of the vinyl acetate is greatly reduced; the powerful adhesive is high in environmental protective performance, excellent in indexes such as thermal stability, initial drying time, water resistance, adhesion strength and curing time and excellent in comprehensive properties.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a strong adhesive. Background technique [0002] At present, with the development of the economy and the change of people's ideas, the lifestyle of returning to nature has become a trend, and how to realize the harmony and unity of people and the environment has become an important thought in the practice of home building life. Chinese traditional culture attaches great importance to the five elements. The guiding ideology of the five elements has been widely practiced in various fields of life. The "five elements" include metal, wood, water, fire, and earth, among which water generates wood, wood generates fire, fire generates earth, earth generates metal, and metal generates water. , and then realize the cycle, endless life, and the five elements are born together. And "wood" has a particularly important position in the five elements. Among the five elements, the only thing ...
