Abstract

The invention discloses a bionic modified plant fiber modified soybean protein adhesive and a preparation method thereof. The preparation method comprises the following steps: taking soybean meal protein as a main body of the adhesive, and adding bionic modified plant fibers and auxiliary agents such as tannic acid to enhance the water-resistant adhesive property of the soybean meal protein adhesive. The bionic modified plant fiber modified soybean protein adhesive has the advantages that the nano structure of gecko toes and the chemical components of mussels are combined to modify the plant fibers, and the interface binding force between the fibers and a matrix is effectively enhanced; the adhesive prepared from renewable and environment-friendly soybean meal protein, the plant fibers andtannic acid has the advantages of high adhesive strength, good water resistance, low cost, sustainability, environmental friendliness and the like; and a glued board has no formaldehyde release, so that the problem of indoor air formaldehyde pollution caused by boards glued by an aldehyde adhesive is thoroughly solved.

Description

technical field [0001] The invention relates to the field of wood adhesives, in particular to a bionic modified plant fiber modified soybean protein adhesive and a preparation method thereof. Background technique [0002] At present, in the glue used in my country's wood industry, aldehyde adhesives occupy a major position, with a market share of more than 80%. However, aldehyde adhesives will continuously release a large amount of free formaldehyde during the processing and application stages, causing serious environmental problems and threatening people's health. In addition, aldehyde adhesives are mostly derived from petroleum-based fossil resources and are non-renewable. With the depletion of earth resources, people are paying more attention to the shortage of resources. It is imperative to develop a green and environmentally friendly bio-adhesive. Row. [0003] Soybean protein adhesive is an environmentally friendly renewable biomass adhesive. Its raw material is rene...
