Abstract

The invention relates to an environmental protection adhesive, and belongs to the high-molecular chemical field. The main components of the adhesive comprise PVA, sweet rice flour, branched chain starch maize, oxalic acid, aqueous phenolic resins, coupling agents, OP-10, a filling material and water. The environmental protection adhesive contains no formaldehyde, is green and non-toxic and meets the E0-grade standard fully, the bonding intensity meets the national requirements, the application environments are widened, and the long-term problem of practical application of an environmental protection adhesive is solved.

Description

technical field [0001] The invention relates to wood adhesives, in particular to an environment-friendly adhesive. Background technique [0002] Adhesives are now widely used in various fields such as transportation, instrumentation, electronic appliances, textiles, construction, wood processing, interior decoration, and daily necessities. Most of the existing adhesives contain formaldehyde, which is harmful to human health when used. Contents of the invention [0003] The object of the present invention is to overcome the defects of the above-mentioned prior art and provide an environment-friendly adhesive, which does not contain formaldehyde and is a green product. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: an environment-friendly adhesive contains the following components by weight percentage: [0005] [0006] Further, the coupling agent KH-550 or titanate. [0007] Further, the filler is light calci...
