Improved wood floor adhesive

Abstract

The invention discloses an improved wood floor adhesive which is prepared from the following raw materials in part by weight: 1.5-3.7 parts of diethanol amine maleic anhydride complex ester, 0.8-1.7 parts of poly(epoxy glycerin ether), 2-3.7 parts of butyl acetate, 3-7 parts of asbestos powder, 0.6-1.5 parts of diisocyanate, 2-3.5 parts of monoglyceride decanoate, 1.3-3.5 parts of glycidyl trimethyl ammonium chloride-gliadin-glyoxal resin, and 0.5-2.7 parts of natamycin. Compared with the conventional product, the improved wood floor adhesive is nontoxic, contains no methanal, does not pollute the environment, has excellent bonding effect as the adhesive property and hot-melting performance of the glycidyl trimethyl ammonium chloride-gliadin-glyoxal resin are high, and is long in service life; the improved wood floor adhesive is high in bonding performance and excellent in mechanical property, and has insect prevention effect; the termite erosion can be effectively prevented by virtue of the combination of the natamycin and the monoglyceride decanoate, so that the possibility of insect attack is reduced; the production technology is simple, the production cost is low, and the popularization is facilitated.

Description

technical field

[0001] The invention relates to an improved wooden floor adhesive, which belongs to the field of building materials. Background technique

[0002] Termites are worldwide pests, distributed in 40% of my country, especially in tropical and subtropical regions, with the characteristics of concealment, universality and severity. Termites not only bring great harm to industry and agriculture, but also one of the main household pests, seriously damaging wood and its products. Wooden floors are also susceptible to decay by termites and silverfish. How to effectively prevent is a problem that we must face and solve. At present, the adhesives widely used in construction are mainly water-soluble polyvinyl formal adhesives and aldehyde adhesives. Their disadvantage is that they all contain volatile formaldehyde, which not only pollutes the environment, but also damages the user's body. healthy. Therefore, developing a formaldehyde-free, insect-resistant adhesive is ...
