Description
Technical field
The present invention relates to a kind of modified corn protein Preparation tackiness agent and shaving board technology, relate in particular to the preparation technology of a kind of environmentally friendly biological adhesive and shaving board, belong to tackiness agent and wood-based plate field.
Background technology
With the corn is the enterprise that raw material carries out deep processing, as producing the factory of products such as starch, Dian Fentang, organic acid, amino acid, all can produce a large amount of tankage.In these tankage, approximately can isolate the Zein powder that accounts for raw materials quality 5%～6%, its main protein is a zein.Zein has unique solvability, and it had been both water insoluble also to be insoluble to anhydrous alcohols, but is dissolvable in water in 60%～95% aqueous alcohol solutions.Because zein is water insoluble and lack essential amino acids such as Methionin, tryptophane, also there are a series of problems such as color and luster and smell, its nutritive value is extremely low, thereby less being applied in the food raw material, at present except that small part is sold as the low value feedstuff protein, many factories in addition do not do any utilization and naturally the discharging, both wasted valuable biomass resource, caused the serious environmental pollution again.
Shaving board is compared with other wood-based plates, produce that investment is less relatively, energy consumption is little, cost is low, not high to the specification of quality of wood raw material, its raw material sources are extensive, have the better physical mechanical property, are widely used in industries such as finishing, furniture, building materials and kitchen tools.Yet the three-aldehyde glue that is widely used in shaving board production at present derives from non-renewable petroleum resources, easily discharges free formaldehyde, serious environment pollution, and harm humans health under hygrothermal environment for a long time.Along with rising steadily and the day by day enhancing of people to awareness of safety and environmental consciousness of crude oil price, it is particularly outstanding that this problem becomes.Obtain the attention of more and more national based on the environmentally friendly Study on Particleboard of renewable resources.At present, the process study that modification prepares tackiness agent and shaving board at zein is almost blank.
Summary of the invention
The technical problem to be solved in the present invention provides the method for a kind of modified corn protein Preparation tackiness agent and shaving board, use this method can realize the nontoxic cleaner production of odorless of shaving board, obtain a kind of environmentally friendly green sheet that free formaldehyde discharges that do not have, improve the quality scale of shaving board product, and promote the increment utilization of corn processed residuum-zein and the recycling of forestry industrial wood waste.
In order to solve the problems of the technologies described above, the invention provides a kind of preparation method of modified corn protein adhesive, may further comprise the steps:
1) by following any one method preparation modifying agent solution:
A: the ethanol of 80～90 parts by volume and the water uniform mixing of 20～10 parts by volume are made ethanolic soln, and the methylene dichloride with 15～35 parts by volume adds in the ethanolic soln of 85～65 parts by volume then, stirs, and obtains modifying agent solution;
B: the ethanol of 80～90 parts by volume and the water uniform mixing of 20～10 parts by volume are made ethanolic soln, the oleic acid of 3～15 parts by volume is added in the ethanolic soln of 97～85 parts by volume, stir, obtain modifying agent solution;
C: the ethanol of 80～90 parts by volume and the water uniform mixing of 20～10 parts by volume are made ethanolic soln, the glycerol of 5～20 parts by volume is added in the ethanolic soln of 95～80 parts by volume, stir, obtain modifying agent solution;
2) modulation modified corn protein adhesive:
Zein is added in the modifying agent solution, and the mass concentration that makes zein is 0.2～0.4kg/L, stirs 1～2h under the room temperature, promptly gets the modified corn protein adhesive.
The present invention also provides a kind of aforementioned modified corn protein adhesive to prepare the method for environmentally friendly shaving board, may further comprise the steps:
1) produce wood shavings:
The forestry processing waste of natural air drying is pulverized through beater disintegrating machine, obtains wood shavings behind sorting, removal impurity and the dust;
2) applying glue:
With modified corn protein adhesive and wood shavings uniform mixing, the solid content of modified corn protein adhesive: the weight sum of the solid content of the dry-matter of wood shavings and modified corn protein adhesive is 13～18: 100;
3) moisture is regulated:
Use the moisture conditioning equipment, the water ratio of regulating previous step gained mixture is 15%～23%, gets slab;
4) hot pressing:
With slab preheating 3～8min, the hot repressing moulding gets shaving board.
As a kind of improvement, the solid content of described modified corn protein adhesive: the weight sum of the solid content of the dry-matter of wood shavings and modified corn protein adhesive is 16: 100.
As a kind of improvement, described wood shavings are wood wool or bamboo shaving, and the granularity of wood shavings is 2～6mm.
As a kind of improvement, the processing parameter of described heat-press step is: 160～190 ℃ of temperature, pressure 5～9MPa, time 40～80s/mm.
As a kind of improvement, the hybrid mode in the described applying glue is: utilize pressurized air to make the wood shavings in the cylinder be suspended state, evenly be sprayed on wood shavings on vaporific the modified corn protein adhesive; Swing roller further evenly stirs modified corn protein adhesive and wood shavings simultaneously.
Among the present invention, what the solid content of modified corn protein adhesive was represented is: the content of zein in the modified corn protein adhesive.What the time 40～80s/mm of heat-press step represented is: the shaving board of suppressing every mm thickness needs the time of 40～80s.
Beneficial effect of the present invention is:
1, adopts the modified corn protein adhesive, can realize the nontoxic cleaner production of odorless of shaving board.
2, prepared shaving board does not have free formaldehyde release, is using the biological degradation easily of discarded back, and compliance with environmental protection requirements is a kind of environmentally friendly product;
3, zein of the present invention derives from the residuum after the starch wet processes, and it is wide, renewable to originate, and can promote the increment utilization of zein and the recycling of forestry industrial wood waste;
4, preparation technology is simple, and physical and mechanical property is suitable with the three-aldehyde glue shaving board.
