Description
Technical field
The present invention relates to adhesive technical field, particularly relate to a kind of soybean-based osseocolla sheet material adhesive and preparation side thereof
Method.
Background technology
Aldehyde system adhesive consumption in timber industry adhesive is maximum, but it exists shortcomings: primary raw material multi-source
In the non-renewable resources such as oil, coal;Produce and use process constantly distributes carcinogen (such as formaldehyde), can be good for by harmful to human
Health;Product non-degradable, easily pollutes environment.Therefore, biomass-based adhesive is researched and developed to substitute aldehyde system adhesive by the whole world
Pay much attention to.In various biological materials, Semen sojae atricolor (including genetically engineered soybean) has that yield is big, low cost, vegetable protein contain
Measure high feature, be good adhesive raw material;Research soybean-based adhesive so that it is all or part of petroleum replacing base gluing
Agent, to reduce depletion of non-renewable resources, ensure food safety the most significant, be outside Present Domestic research focus；
Adhesive the most nontoxic, free of contamination is applied to become trend, plant along with using the exploitation of reproducible biomass from producing to
The research of albumen adhesive causes the extensive concern of people.Wherein, utilizing soybean protein to prepare soybean-based adhesive is study hotspot,
Improving its resistance to water is then primary study content, and it is the most resistance to that oneself there are some researches show that adhesive prepared by soybean protein isolate has
Aqueous；But, SPI is isolatable from Semen sojae atricolor defatted soy flour, and the price of its costliness necessarily limits its application in terms of adhesive.Cause
This, the DSF of cost and low percentages of protein becomes the preferred raw materials preparing water-resistant soybean base adhesive；
SPI and DSF, SPI that after preparation soybean-based adhesive mainly uses soybean extract oil at present, defat bean cypress produces derive from
DSF, its soybean protein content is typically larger than 90%, it is easy to modified, the adhesive of preparation has good resistance to water.But SPI costliness
Its application in terms of adhesive of price limit.Therefore, the DSF of cost and low percentages of protein become preparation resistance to water big
The preferred material of bean base adhesive.A large amount of research methoies based on SPI adhesive are also used for modified DSF and prepare adhesive, and
Achieve certain effect, it is thus achieved that low resistance to water (cold water or humid air), medium resistance to water (63 DEG C of water) and enhanced water resistance
The modified soybean base adhesive formula of (boiling water);Wherein, enhanced water resistance soybean-based adhesive is mainly by excellent with boiling water resistance energy
Obtain after different synthetic resin mixing.But, DSF is complicated mixture, by the soybean protein of nearly 50%, the carbon hydrate of 40%
Thing and other micro constitutent form；
Current research method all lays particular emphasis on modified soybean protein therein, and is not directed to the carbohydrate of 40%, causes this
Resistance to water after adhesive is solidified by component is inoperative, even plays negative interaction, wastes raw material.Additionally, have resistance to boiling
Aqueous can be adhesive for making the precondition of outdoor cementing thing, if when with DSF glue so that it is in carbon hydrate
Thing converts the component that raising adhesive resistance to water rises positive interaction, in conjunction with Soybean Protein Modification method, prepares the bean of resistance to boiling water base
Adhesive, not only takes full advantage of raw material, can be also that a new way is opened up in the soybean-based adhesive research being applied to open air.
The research solving problem that aldehyde system adhesive exists and the based Wood Adhesives that instructs other similar biomass to be raw material is all anticipated by this
Justice is great；
Epoxy radicals is the polar group that a kind of work is dialled, and can form chemistry and be bonded with the radical reaction containing active oxygen, utilize containing epoxy
The compound on organism matter adhesive of group is modified improving research existing many reports of its performance, if therefore used
Containing epoxy compounds, it is modified, or access ring epoxide in the component containing these functional groups, necessarily can carry further
High Semen sojae atricolor base adhesive resistance to water.
