Problems solved by technology

Most of the existing common adhesives are artificially synthesized chemical adhesives. Most of them have the problem of large amount of formaldehyde release, which is harmful to human health. Therefore, people gradually turn their direction to make adhesives with natural ingredients. Among them Soybean gum has the characteristics of sustainable production and is a good adhesive matrix component, but it has the problem of relatively low viscosity, which leads to poor mechanical properties of the board.

Abstract

The invention discloses a soybean-glue-based adhesive for a medium-density fiberboard, and relates to an adhesive. The soybean-glue-based adhesive is concretely prepared from soybean glue, bone glue, albumen, casein, deionized water, modified filler, a defoaming agent, emulgator, plasticizer, curing agent and preservative. The prepared adhesive is good in adhesion effect and capable of effectively improving the mechanical property of the medium-density fiberboard, the static bending intensity can be improved by about 15%, the inner bonding strength is promoted by 20% or more, and the medium-density fiberboard is free of toxic components and is high in use safety.

Description

technical field [0001] The invention relates to an adhesive, in particular to a bean gum-based adhesive for medium density fiberboards. Background technique [0002] MDF is a man-made board made by mechanically separating and chemically treating wood or plant fibers, adding adhesives and waterproofing agents, etc., and then molding under high temperature and high pressure. It is an ideal man-made board for making furniture. The structure of medium-density fiberboard is more uniform than that of natural wood, and it also avoids problems such as decay and insects. At the same time, it has small expansion and contraction and is easy to process. Most of the existing common adhesives are artificially synthesized chemical adhesives. Most of them have the problem of large amount of formaldehyde released, which is harmful to human health. Therefore, people gradually turn their direction to make adhesives with natural ingredients. Among them Soybean gum has the characteristics of su...
