Abstract

The invention relates to an environmental-friendly adhesive and belongs to the field of high polymer chemistry. The environmental-friendly adhesive mainly comprises the following components: PVA (Polyvinyl Alcohol), glutinous rice flour, branched corn starch, oxalic acid, water-based phenolic resin, a coupling agent, OP-10, fillers and water. The environmental-friendly adhesive disclosed by the invention does not contain formaldehyde, is green and non-toxic and completely reaches the E0-level standard, the bonding strength meets the national specified requirement, the application environment is widened, and the problem troubling the actual application of the environmental-friendly adhesive for a long time 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...
