Abstract

The invention discloses a bean-pulp-based adhesive for modified materials and a preparation method of the bean-pulp-based adhesive. The adhesive is prepared by 25-35 parts of low-temperature degreased protein powder, 3-8 parts of active agent, 0.1-0.8 part of catalyst, 5-10 parts of enhancer, 0.2-1 part of curing agent and 70-80 parts of dispersion medium. The preparation method includes dispersing, mixing, heating, homogenizing, emulsifying, stirring and the like. The bean-pulp-based adhesive and the preparation method thereof have the advantages that the water resistance requirements of the adhesive for the transverse splicing of the modified materials can be satisfied, and the practical performance of the protein adhesive is guaranteed; the problems of low modified material transverse splicing strength and organic volatile pollution are solved thoroughly; the main raw materials of the adhesive are renewable resources and conform to the principles of environment protection and sustainable development.

Description

technical field [0001] The present invention relates to an adhesive and its preparation method, in particular to a soybean meal-based adhesive for modified materials and its preparation method, which is used for normal temperature curing of modified poplar, and belongs to adhesive and its preparation method field. Background technique [0002] With the improvement of people's living standards and the continuous and stable development of construction, decoration, packaging and other industries, my country's demand for wood continues to increase and decrease, but the wood that can be used for furniture manufacturing has a long growth cycle and slow growth, which cannot meet the growing demand. timber demand. Fast-growing wood, mainly fast-growing poplar, has a large growth cycle and output, but the material of the fast-growing wood is poor, and the density is only 0.32g / cm 3 , equivalent to half the density of hardwood for furniture, easy to deform, poor nail holding power, a...
