Description
Technical field
The invention belongs to adhesive and its preparation field, and in particular to a kind of soybean protein for being mainly used in based Wood Adhesives
Adhesive and preparation method thereof.
Background technology
At present, the Lauxite of Form aldehyde release mainly is used as adhesive in based Wood Adhesives.With people couple
The concern that wooden boards Form aldehyde release is detrimental to health, the adhesive such as soy protein adhesives of some formaldehydeless additions start
Cause the attention of people.Because soy protein adhesives water resistance is poor, it is necessary to which timber glue could be used for by improving its water resistance
Glutinous agent is to meet requirement of the use environment to water resistance, some modification technology means such as application number 102719217A
（2012.10.10）Chinese invention patent be modified using alkali and modifier, wherein modifying agent is preferably urea, with
Improve water resistance；Such as application number 101629019A（2010.01.20）The modifying agent that uses of Chinese invention patent also use urine
Element.Due to addition of the urea in adhesive, the wooden boards made using the adhesive for having urea to add have ammonia release,
Indoor environment is caused " ammonia pollution ".Traditional " ammonia pollution " adds urea as antifreezing agent in concrete, and
Additive is used as using ammoniacal liquor when ornament materials is covered with paint, lacquer, colour wash, etc. indoors.Ammonia is gas a kind of colourless and with intense irritation stink
Body, it has corrosion and stimulation to the skin histology contacted, can absorb the moisture in skin histology, make histone
Denaturation, and make tissue fat saponification, destroy membrane structure.During excessive concentration in addition to corrosiveness, it can also pass through trigeminal neuralgia
The acting in opposition of tip and cause cardiac arrest and breathing stop.Using modifying agent of the urea as soy protein adhesives, meeting
Increase " ammonia pollution " of product use environment, can equally be detrimental to health.Meanwhile, some use fossil resources for primary raw material
Production such as polyamine epichlorohydrin resin（PAE）Deng the crosslinking agent as soy protein adhesives, cause adhesive can not
Biodegradable, its discarded object pollutes generation environment.
The content of the invention
An object of the present invention is to provide a kind of soy protein adhesives.
The soy protein adhesives of the present invention, are prepared from by the raw material of following parts by weight：The water of 100 parts by weight, 10-30
The soyabean protein powder of parts by weight, the alkali of 0.5-5 parts by weight, the polyol agent of 5-60 parts by weight, the crosslinking agent of 5-20 parts by weight,
The preservative of 0.1-0.5 parts by weight, the defoamer of 0.1-2 parts by weight.
Specifically, the soyabean protein powder is using soybean processing residue dregs of beans as raw material, formed by grinding, albumen contains
Amount >=50%.
Preferably, the soyabean protein powder is low denatured soybean protein powder；Low denatured soybean protein powder is soybean using sudden strain of a muscle
The defatted soybean meal that steaming precipitation technique is obtained is the soyabean protein powder of Raw material processing, there is more preferable dispersiveness in water.
Specifically, the alkali is sodium hydroxide.
Specifically, the polyol agent is the mixture of one or both of propane diols, glycerine, sorbierite.
Specifically, the crosslinking agent is dialdehyde starch.
Specifically, the preservative is benzisothiazole-3-ketone.
Specifically, the defoamer is methyl-silicone oil or bean plant oil.
The adhesive of the present invention is mixed and modified using alkali and the progress of polyalcohols material, and polyalcohols material is to soybean protein
There is plasticising, the soybean protein excessive degradation that can prevent alkali modification from causing, the space for maintaining soybean protein moderately to degrade
Structure, makes soy protein adhesives have good water resistance；Meanwhile, use dialdehyde starch for crosslinking agent, dialdehyde starch is one
The carbonyls of kind of high reaction activity, can carry out cross-linking reaction with soybean protein, and dialdehyde starch is so that originate widely can be again
Raw plant resources is primary raw material, than using other such as daiamid epoxy chlorine third of the crosslinking agent using fossil resources as primary raw material
Alkane resin（PAE）Deng with more the feature of environmental protection, and with biodegradable advantage.
The second object of the present invention is the preparation method for providing above-mentioned soy protein adhesives, and it comprises the following steps：
The polyol agent of the water of 100 parts by weight, the alkali of 0.5-5 parts by weight and 5-60 parts by weight is made into modified solution, stirred
After 5-30 minutes, disappearing for the soyabean protein powders of 10-30 parts by weight, the preservative of 0.1-0.5 parts by weight and 0.1-2 parts by weight is added
Infusion, stirs and forms within 30-90 minute uniform colloid, then adds the crosslinking agent stirring of 5-20 parts by weight to obtain after 30-90 minutes
Soy protein adhesives.
The preparation method of the present invention, the addition in process of production without the Ammonia material such as ureaformaldehyde, while also formaldehydeless addition,
The adhesive of preparation reaches environmental-protecting performance and the good purpose of water resistance without " ammonia pollution " and " formaldehyde pollution ".Using can be again
Production-goods source dialdehyde starch is crosslinking agent, has natural resource and environment with respect to other fossil resources for the crosslinking agent of primary raw material
Advantage, the environmental-protecting performance of adhesive is further lifted from biodegradable angle.
Embodiment
With reference to specific embodiment, the present invention is described in further detail.

The present invention has found that polyol agent can prevent list using alkali and polyol agent modified soy-bean protein through development test
Hydroxyl in the soybean protein excessive degradation that pure alkali modification is caused, polyol agent can carry out anti-with the group of soybean protein
Should, the effect of plasticising is served as in soybean protein structure, it is possible to decrease palliating degradation degree of the alkali to soybean protein；And polyol agent
It is strong to polar substances solvability, many polar groups are contained in the peptide chain structure of soybean protein, polyalcohol is to improving soybean egg
Dissolubility in Bai Shui has improvement, the space structure for being conducive to soybean protein to be stablized, soybean protein molecular structure
In amino can with crosslinking agent dialdehyde starch carry out cross-linking reaction, formed with good water resistance can and bonding strength soybean egg
White adhesive.
It is modified to reduce the palliating degradation degree to soybean protein using alkali and urea, is due to that alkali can give birth to urea reaction
Into ammonia, carbonate and water, so that the palliating degradation degree to soybean protein is reduced, but the addition of urea can be caused " ammonia pollution ", this
Invent no urea and the addition of Ammonia material；Meanwhile, crosslinking agent uses dialdehyde starch, and dialdehyde starch is so that originate widely can be again
Raw plant resources is raw material, than using other such as daiamid epoxy chlorine third of the crosslinking agent using fossil resources as main material production
Alkane resin（PAE）With more the feature of environmental protection, and with biodegradable advantage.
Provide to carry out the measure of bonding strength, the intensity of three layers of poplar plate according to standard GB/T/T 17657-1999
