Description
Technical field
The present invention relates to a kind of making method of epoxy resin modified soy protein adhesive, this soybean albumen adhesive mainly is used in the production of wood gluing plate and furniture is made, and belongs to the wood adhesive technical field.
Background technology
The research of soybean-based adhesive starts from nineteen twenty-three, owing to the adhesive made of synthetic resin that with petroleum chemicals is raw material has better adhesiveproperties and water resistance, so soybean-based adhesive is substituted gradually.In recent years, along with the continuous expansion in tackiness agent market, problems such as the finiteness of global petroleum resources and environmental pollution cause people's attention gradually; And adhesive made of synthetic resin can cause great harm because of containing toxic substances such as formaldehyde, phenol to environment and HUMAN HEALTH in production, transportation and use.Therefore, adhesive industry must consider to use reproducible, environmentally friendly tackiness agent.Because soybean-based adhesive is environmentally friendly tackiness agent, can substitute adhesive made of synthetic resin on the performance, thereby soybean-based adhesive becomes the focus of research again.
But find that in the triturating of soybean-based adhesive this two is difficult to the technical barrier that breaks through greatly its cohesive strength and water tolerance, is to hinder the bottleneck problem that soybean-based adhesive is promoted.Therefore, improve rubber made from soybean cake cohesive strength and water tolerance, satisfy industrial application requirements, be the key of current soybean-based adhesive development research.
Resins, epoxy be meant contain the epoxy group(ing) structural formula in the molecular structure, be the polymkeric substance of main chain with aliphatics, alicyclic or aromatic series segment, liquid and solid epoxy two big classes are arranged, since beginning to use the 1950's, development is very fast, it is not sticking almost not have institute, in one's favour always not waning, be performance comparatively comprehensively, use a resinous materials quite widely, have the good reputation of " multi-purpose adhesive ".Resins, epoxy has the characteristic of many excellences, big as bonding force, bonding strength is high, cure shrinkage is low, dimensional stability is good, resistant to chemical media, applied widely, toxic is very low, non-environmental-pollution etc., multiple materials such as metal, plastics, timber, pottery, glass, matrix material all there is good cementability, but the Resins, epoxy price is more expensive, it is higher to make the tackiness agent cost, so generally be not suitable for the production of wood gluing plate and the manufacturing of furniture.
To be suitable for the soybean albumen adhesive that wood-based plate uses in order preparing, to disclose certain methods so far.At Chinese invention patent ublic specification of application (publication number: CN101302417), proposed soybean protein and water were mixed through 10 minutes, adding slaked lime mixed and stirred 10 minutes, add water glass, sodium peroxide again, the soy protein adhesive of preparation can be used for plywood industry after stirring in 15 minutes.At Chinese invention patent ublic specification of application (publication number: CN101255328), introduced organic solvent ethanol modified soy protein adhesive technology.More than two kinds of methods just introduced the making method of soybean albumen adhesive for example, the water resistance of tackiness agent and bonding strength also have the space that further promotes.(publication number: CN101130678), provide a kind of aquosity polymer isocyanic ester adhesion agent of soy protein, the linking agent of selecting for use in tackiness agent is a polyisocynate monomer at the Chinese invention patent ublic specification of application.As everyone knows, the isocyanic ester raw materials cost is higher, is unfavorable for the widespread use of soybean albumen adhesive.
