Description
Technical field
The invention belongs to timber aldehyde-free cement technical field, more particularly to a kind of aldehyde-free cement of soybean protein-containing
And preparation method thereof.
Background technology
In recent years, developing rapidly with wood-based panel industry, wood adhesive consumption increases severely, wherein " three-aldehyde glue (ureaformaldehyde
Glue, phenol glue, carbamide glue) " the 80% of the industrial adhesive of Wood and artificial board is occupied, due to these three resins
All with formaldehyde as raw material so that inevitably contain a certain amount of formaldehyde in resin adhesive.
As people improve to health and the consciousness of environmental protection, various countries are to also more tight containing content of formaldehyde control in wood-based plate
Lattice, so that so that the soybean adhesive containing vegetable protein turns into study hotspot again.
Occurs the patent of first peas protein adhesive early in nineteen twenty-three, to the fifties, it is glued that soybean adhesive accounts for the U.S.
Plate market 85%.But because soybean adhesive working life at that time is short, poor water resistance, the air aldehyde resin for gradually being occurred later
Glue replaces；Additionally, due to soybean adhesive poor water resistance, initial bonding strength is small, adhesion strength is low, modified high cost, fungicidal properties are poor
Etc. reason, also limit its application and develop.The U.S. was successfully proposed the soybean of trade name Purebond without aldehyde gluing in recent years
Plate, promotes California Air to manage administration and proposed to the permission burst size of methanal of various glued boards and compares E0(≤0.5mg/L) more
It is strict new demand.
Many countries had carried out the research of soybean aldehyde-free cement in recent years so that its water resistance is improved significantly, into
This and technique are also received.In the prior art, by the modified water resistance that can improve protein adhesive to legumin, but and phenolic aldehyde
The water resistance of glue is larger compared to gap, and the wet strength difference particularly after boiling water boiling is bigger.Additionally, using synthetic resin to soybean
Protein adhesive is modified, and is crosslinked with phenolic resin and legumin, is made into low viscous adhesive, it is adaptable to medium density fibre board (MDF)
Manufacture；It has the disadvantage equally to contain formaldehyde in phenolic resin, it is impossible to accomplish without aldehyde glue.Also by phyllosilicate to soybean egg
White adhesive modification, because phyllosilicate is the widely used modifying agent of macromolecular material, is also widely applied to adhesive
It is modified；The mechanism of action is, by ion exchange, to make phyllosilicate that stripping or intercalation configuration are formed in soybean protein, is entered
One step forms composite construction with soybean protein, improves the tack of soybean albumen adhesive, intercepts immersion of the moisture to glue-line, carries
The water resistance of soybean protein glue high.It has the disadvantage that, with the increase of phyllosilicate addition, the viscosity of system increases, causes
The difficulty that bubble overflows increases therewith, and obtained adhesive air bubble content is more more necessarily to cause apparent viscosity to decline.
Therefore, it is necessary to further be improved soybean adhesive.
The content of the invention
The invention aims to overcome the shortcomings of soybean adhesive in the prior art, there is provided a kind of soybean protein-containing
Aldehyde-free cement and preparation method thereof.The present invention, as base material, uses surfactant, modifier metal using soybean protein
Oxide and hydroxide and crosslinking agent are to soybean protein comprehensively modifying, so as to improve the adhesive strength of soybean albumen adhesive
And water resistance.
A kind of aldehyde-free cement of soybean protein-containing, is aoxidized by soybean protein, surfactant, alkali compounds, metal
Thing, crosslinking agent and water composition；
Wherein, the soybean protein is adhesive principal component, and the amount of the surfactant is the soybean protein weight
1-10%, the amount of the alkali compounds is the 3-15% of the soybean protein weight；The amount of the metal oxide is institute
The 5-20% of soybean protein weight is stated, the amount of the crosslinking agent is the 3-20% of soybean protein weight, and the amount of the water is soybean
2-5 times of protein by weight；
Above-mentioned surfactant is anion surfactant or cationic surfactant, and preferred anionic surface is lived
One or two in dodecyl sodium sulfate (SDS) and neopelex (SDBS) in property agent；
Above-mentioned alkali compounds is the hydroxide of IA races, IIA and III A races metal, preferably NaOH, hydroxide
One or more in potassium, magnesium hydroxide and aluminium hydroxide；
Above-mentioned metal oxide is one or more in magnesia, calcium oxide and zinc oxide；
Above-mentioned crosslinking agent is daiamid epoxy alkyl halide resin, specially polyamine epichlorohydrin resin and polyamide
One or two in epoxy bromopropane resin.
Present invention also offers the preparation method of the aldehyde-free cement of above-mentioned soybean protein-containing, comprise the following steps：
1) take soybean protein according to the above ratio and surfactant is added to the water stirring to being completely dissolved；Surfactant pair
Soybean protein is modified, and makes soybean protein hydrophobic grouping outwardly, is effectively increased the hydrophobicity of soybean protein；
2) in proportion to adding alkali compounds in solution, and stir to being completely dissolved；By the alkaline hydrolysis of alkali compounds
Effect, makes soybean protein molecule disperse and launch, and polarity and non-polar group fully expose；Further, since pH value is modified to SDS
The water-fast intensity of soybean albumen adhesive has an impact, and with the rising of pH value, the water proof bonding strength of soybean albumen adhesive is sent out
The trend of changing is first to increase to reduce afterwards, and it is gluing that the present invention adds the alkali compounds of soybean protein weight 3-15% to make
The water proof bonding strength of agent is in optimum range；
3) in proportion to adding metal oxide in solution, and stir to being completely dissolved；In view of the product for smearing adhesive
After the heated pressurized treatments of product, adhesive meeting desiccation, dried adhesive can be subject to the shadow from air and surrounding steam
Pilot causes the dry strength to reduce, and addition metal oxide can play a part of absorption air and surrounding steam, to reduce to gluing
The influence of agent dry strength；
4) to daiamid epoxy alkyl halide resin is added in solution it is in proportion crosslinking agent, and stirs to being completely dissolved, i.e.,
Obtain aldehyde-free cement product；Because daiamid epoxy alkyl halide resin is the quaternized polyamide of alkyl halide containing epoxide group,
Its epoxide group is reacted with the amino in soybean protein molecule, forms the compound containing epoxide group；What is formed is compound
Thing can continue to be reacted with nitrogen-containing compound, be formed under the conditions of suitable temperature and pressure (i.e. during glued board is manufactured)
Tridimensional network, the tridimensional network of this crosslinking has water resistance and cross-link intensity so that the water resistance of adhesive and
Dry strength is all improved.
The application method of the aldehyde-free cement of above-mentioned soybean protein-containing, comprises the following steps：
Described aldehyde-free cement is smeared on product to be bonded, glue-spread is 300~600g/m2, digestion time 10~
30 minutes；
Then, product to be bonded is pressed on press, the product after compacting is placed 18~24 hours at room temperature；Pressing
Process conditions are：1.2~1.5Mpa of pressure, 110~140 DEG C of temperature, 0.5~1min/mm of time.
Compared with prior art, advantage of the invention is that：
1st, adhesive of the invention is changed using surfactant, alkali compounds and metal oxide to soybean protein
Property, then improve cross-link intensity by adding crosslinking agent, soybean albumen adhesive water resistance and adhesion strength can be increased substantially.
2nd, adhesive of the invention does not use formaldehyde as raw material, and constituent soybean protein, surface-active again
Agent, alkali compounds, metal oxide, crosslinking agent are nontoxic, health environment-friendly.
3rd, adhesive dry strength 5.0~7.2Mpa of scope of the invention, is fully achieved II class glue and uses standard, and have
Price is relatively low, function admirable, the advantages of be easy to applying glue.
