Problems solved by technology

Protein glue uses biomass as raw material, and its raw material has the advantages of wide source and renewable; if no harmful petrochemical raw materials such as formaldehyde and phenol are added in the production process of protein glue, soybean glue can not only reduce people's dependence on petrochemical products, It can also meet the environmental protection needs of people not to be harmed by indoor formaldehyde. However, the existing protein adhesives generally have cracking phenomenon when coated on wood boards, and the viscosity is not enough, and the fluidity is high. Holes in the board lead to many defects such as lack of glue on the surface of the board

Abstract

The invention discloses an egg white-based wood adhesive. The egg white-based wood adhesive comprises the following components: egg white, deionized water, grafting monomers, filler and auxiliaries. A preparation method of the egg white-based wood adhesive comprises the following steps: modifying the egg white as a raw material by adopting glycidyl methacrylate and a water-based epoxy resin mixture as grafting monomers through graft copolymerizing method to prepare the wood adhesive. The adhesive is free of formaldehyde, green and environmentally friendly, has good water resistance, storage stability, high bonding strength and relatively low liquidity and low preparation cost, and is economically affordable.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to a wood adhesive prepared from egg white as a main raw material. Background technique [0002] With the rapid development of my country's economy, the urban construction and indoor and outdoor decoration industries have developed rapidly, and the demand for adhesives in my country has grown rapidly. The average annual growth rate has been around 20% for more than 10 years. Among them, three aldehyde glues (urea-formaldehyde, phenolic and Melamine formaldehyde resin glue) has the largest demand, yet, trialdehyde glue will cause environmental pollution problems due to releasing harmful free formaldehyde and phenol during manufacture, transportation and use; especially in interior decoration and furniture panels, because formaldehyde It is not completely condensed, and often a considerable part exists in a free state, which will gradually disperse to the surroundings and cause environmental po...
