Abstract

A protein adhesive and a preparation method thereof belong to the technical field of adhesives. A protein adhesive, comprising the following raw materials in parts by weight: 90-150 parts of water, 50-80 parts of collagen, 6-12 parts of monomers with amino groups, and 6-10 parts of long-chain alkyl active monomers And 10 to 15 parts of epoxy haloalkane, collagen is extracted from tanning waste. A protein adhesive is obtained by cross-linking collagen, monomers with amino groups, and long-chain alkyl reactive monomers with epoxy halides as cross-linking agents in a water environment. This protein adhesive does not contain any The formaldehyde substance is harmless to the human body. It is a green non-polluting adhesive and is very environmentally friendly. Collagen is extracted from tanning waste to turn waste into treasure and reduce the cost of adhesive synthesis. The preparation method of protein adhesive is simple and convenient, and the active ingredient of the prepared adhesive is relatively high.

Description

technical field [0001] The invention relates to the technical field of adhesives, and in particular to a protein adhesive and a preparation method thereof. Background technique [0002] At present, the adhesive used in the wood / bamboo industry is still based on synthetic resin adhesives, among which the so-called "trialdehyde" glue of urea-formaldehyde resin, phenolic resin and melamine-formaldehyde resin accounts for more than 80% of the glue used in the whole wood / bamboo wood. In the "trialdehyde" glue, the amount of urea-formaldehyde resin exceeds 90%, mainly because urea-formaldehyde resin has a series of requirements such as wide source of raw materials, cheap, easy to use, good initial adhesion, simple manufacturing process, and colorless adhesive layer after curing. Advantages for use as wood / bamboo adhesive. "Trialdehyde" glue has a fatal shortcoming, that is, the wood-based panels made with it will continuously release formaldehyde during the process of manufacture...
