Description
Technical field
The invention discloses a kind of polyvinyl acetate emulsion, belongs to binder material technical field.
Background technology
Polyvinyl acetate emulsion（PVAc emulsions）White glue with vinyl is commonly called as, is with vinylacetate（VAc）For one kind of principal monomer
Important emulsion adhesive, with its simple production process, it is easy to use, cheap, initial bond strength is high the advantages that, extensively
It is that volume of production and marketing is most in the market applied to building decoration, timber, yarn fabric bonding, paper product processing, packaging material numerous areas
One of big kind.But because the water resistance of PVAc emulsions, cold resistance are poor, easily demulsification at low temperature, bonding force is not strong enough,
Prolonged dead weight lower glue layer easily slides.Limit the popularization and application of polyvinyl acetate emulsion.In order to full
The particular/special requirement of the corresponding industry of foot, the application of PVAc emulsions need to be expanded.Researcher has carried out many to PVAc emulsions and changed
Journal of Sex Research, at present study on the modification work mostly use cross-linking method, are changed into thermosetting by thermoplasticity, mainly changed by copolymerization
The methods of property, Protection glue structural reform surname, blending and modifying, is modified.When preparing modification by copolymerization PVAc emulsion adhesives, by breast
Liquid introduces hydroxy-ethyl acrylate when being copolymerized（HEA）, react to be formed with other reactive groups using its crosslinked action in polymerization
Space network, the tensile property after PVAc emulsion plastics can be improved；Butyl acrylate（BA）And ethyl acrylate（EA）Deng
The introducing of soft monomer can improve the water resistance after PVAc emulsion plastics and MFT.Although its heat resistance and water resistance are equal
It is improved, but compared with the market demand, lifting amplitude is little, does not reach expected ideal effect.
In addition, easily generation gel goes bad and loses use value PVAc emulsions at low ambient temperatures.Influence PVAc breasts
The factor of liquid freeze-thaw stability is a lot, includes the characteristic of emulsion itself, the property of protecting colloid, various additives etc., wherein protecting
It is a kind of key factor to protect colloid.In PVAc emulsion systems, emulsion particle surface is adsorbed or be incorporated in a protecting colloid part
Form the protective layer with space steric effect（It is hydrated layer）And stabilization is played, a part is free in aqueous phase.Therefore, remove
The stability of the protecting colloid aqueous solution has an impact to emulsion freeze-thaw stability outer, and protecting colloid function is protective layer and emulsion
The power that burl closes, also directly affect the freeze-thaw stability of PVAc emulsions.Therefore, between heavy seal coat and PVAc polymer particles
Interaction should be able to improve the freeze-thaw stability of emulsion.Complete alcoholysis type polyvinyl alcohol（PVA）With partial alcoholysis type polyethylene
The performance of alcohol protecting colloid and they and vinylacetate（VAc）The existing many researchs of graft reaction, but its effect is thrown away
Have much room for improvement.
Therefore, polyvinyl acetate emulsion water resistance, freeze-thaw stability and mechanical property are improved, turns into it and is more leading
Promote and apply urgent problem to be solved in domain.
The content of the invention
The present invention solves the technical problem of：Poor, the freeze-thaw stability for traditional polyvinyl acetate emulsion water resistance

The preparation process of the tetraethyl orthosilicate microballoon is：Count in parts by weight, take 20~30 parts of tetraethyl orthosilicates successively
With 20~30 parts of paraffin, first heating paraffin is melted, obtains liquid paraffin, and tetraethyl orthosilicate is refrigerated, obtains the positive silicic acid second of cold conditions
Ester, then melt paraffin and cold conditions tetraethyl orthosilicate are produced into tetraethyl orthosilicate microballoon to spray.
The polyallylamine liquid quality fraction 30~40%.
The coconut palm Carbon fiber of 0.01~0.02 times of polyvinyl acetate quality can also be added in the polyvinyl acetate emulsion
Dimension.
The beneficial effects of the invention are as follows：
（1）The present invention is by adding polyallylamine solution, and in use, under room temperature condition, the polyallylamine aqueous solution can
Reacted with Carbon Dioxide in Air, the product for reacting generation spontaneously forms three-dimensional netted knot by electric charge interphase interaction
Structure so that polyvinyl acetate emulsion is dispersed in three dimensional gel network structure；Because three dimensional gell network plays enhancing
The toughness of system, the effect for avoiding system from ftractureing, so during multigelation, can keep good freeze-thaw stability；
（2）The present invention is coated on the tetraethyl orthosilicate microballoon in paraffin by addition, on the one hand, paraffin cladding can avoid preparing
During, tetraethyl orthosilicate hydrolyzes after being contacted with water；On the other hand, in use, the moisture in system is tied to the cold
Ice can cause system internal volume extrudes tetraethyl orthosilicate microballoon after expanding to rupture, and the tetraethyl orthosilicate in microballoon meets water,
Hydrolyze, generate nano silicon, the nano silicon of generation can be attached in system three dimensional gell network, realization pair
The filling of system network structure, strengthen the intensity of system, further improve freeze-thaw stability, water resistance and mechanical property；
（3）The present invention is by adding coconut palm Carbon fibe, in use, on the one hand, coconut palm Carbon fibe enhances the toughness of system；Separately
On the one hand, the moisture in system freezes to the cold, causes tetraethyl orthosilicate microballoon to rupture, and the tetraethyl orthosilicate in microballoon meets water, hair
Unboiled water solution, nano silicon is generated, coconut palm carbon fiber surface contains active group, and the silica of teos hydrolysis generation is inhaled
Coconut palm carbon fiber surface is attached to, improves coconut palm carbon fiber surface roughness, so as to improve coconut palm Carbon fibe and system three-dimensional net structure
Mechanical snap power, further enhancing the intensity of system, so obtain preferable freeze-thaw stability.
