Abstract

The invention relates to an environment-friendly adhesive, and belongs to the field of high polymer chemistry. The environment-friendly adhesive comprises the main components of PVA, glutinous rice flour, branched corn starch, oxalic acid, water-based phenolic resin, a coupling agent, OP-10, a filler and water. The environment-friendly adhesive does not contain formaldehyde, is green and nontoxic and completely reaches the standard of E0 grade; the bonding strength reaches the requirements specified by the state; the application environment is expanded; and the long-term problem of practical application of the environment-friendly 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...
