Abstract

The embodiment of the invention provides a vegetable protein-based adhesive and a preparation method. The vegetable protein-based adhesive of the embodiment of the present invention can significantly improve the dispersibility and stability of the inorganic nano-palygorskite in the vegetable protein stock solution by modifying the surface of the inorganic nano-palygorskite, and reduce the aggregation and settlement. In addition, the inorganic nano-palygorskite Grafting reactive polymers on the stone surface can enhance the participation of inorganic nanomaterials in the curing reaction process of plant protein stock solution, give full play to the advantages of nanomaterials, and become the nodes of the three-dimensional network structure, and enhance the water resistance of plant protein-based adhesives while enhancing Compared with unmodified or directly modified with macromolecular polymers, its bonding strength is significantly improved, and its water resistance is also significantly improved. At the same time, its flame retardant performance is significantly improved, and the highest can reach B1 level.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to vegetable protein-based adhesives and a preparation method. Background technique [0002] In wood-based panel furniture, adhesives are necessary auxiliary materials. As early as 1923, people used soybean flour as the base material to make wood adhesives for plywood. Due to the defects of soybean glue itself, it was gradually replaced by the developed "trialdehyde glue". [0003] At present, although "trialdehyde glue" is the main adhesive for wood-based panels, "trialdehyde glue" mainly uses formaldehyde, urea, melamine and phenol as raw materials, which will release formaldehyde and phenol during production, transportation and use. and other toxic and hazardous substances. Due to the shortage of petroleum resources and the gradual enhancement of people's awareness of environmental protection, it has become an inevitable trend to find new natural environmental pro...
