Description
Technical field
The present invention relates to a kind of aqueous binder, more particularly to it is a kind of opposed polarity plastic basis material and paper wood and timber with
There is excellent tack and the eventually preparation method of the environment-protection nano composite biomass aqueous binder of viscosity between paper wood.
Background technology
As environmental protection, the theory for treasuring resource are increasingly rooted in the hearts of the people, high solids content, solvent-free, water to adhesive
Property, environment-friendly factor and low-temperature setting, the castoff regenerative such as photocuring the power-saving technology such as utilize increasingly to pay attention to, and constantly plus
Big research and development dynamics.The mainly no-solvent type used in flexible packaging industry, European and American developed countries' package compound production
Adhesive and Aqueous Adhesives.At present, the flexible package in China more than 95% is produced using solvent type adhesive, using most
More, performance is preferably solvent-type double-component adhesive for polyurethane.Because solvent type adhesive has excellent flexibility, low temperature resistant
And boiling resistance, ease for operation and extensive adaptability, and the dry complex equipment of domestic Flexible-Packaging Industry is only applicable at present
Solvent type adhesive.In addition, Environment-friendlyadhesive adhesive also also has certain limitation in aspect of performance.With solvent type adhesive phase
Than Aqueous Adhesives have solvent-free release, environment-friendly, nontoxic, non-combustible, safe to use, low cost and other advantages, solid content
Up to 50%-60%, there is the advantage that spread is few, bond strength is high.Aqueous polyurethane（PU）Adhesive, acrylic emulsion,
EVA copolymer emulsions etc..Meanwhile in adhesive field, global trend is that biological material is used while greenization is done step-by-step
Prepared by material, many biomass possess extraordinary cohesive, such as starch, lignin liquid, various colloids in itself.It is domestic at present
The research to biomass adhesive is concentrated mainly on soybean protein, starch, pyrolysis bio-oils and lignin etc. outside.Due to life
The cohesive of material in itself is unable to reach the requirement of commercial Application, and obstructed modification mode be used to improve biological material
Cohesive.Such as access hydrophobic grouping, untie the three-dimensional aggregate structure of biomass molecule chain.Such as patent of invention
The preparation method of a kind of biomass adhesive disclosed in 2011100294798 and its biomass adhesive and glued wood, this hair
It is bright cake of camellia oleifera seeds is contacted with alkali and water after in the presence of polycondensation catalyst, react, obtain under the conditions of polycondensation with phenol and aldehyde
To the biomass adhesive component that viscosity is 500-5000 centipoises；And for example one kind is separated with soybean disclosed in 2009100843660
Albumen is the preparation method of the biomass adhesive of major ingredient, by the way that soybean protein isolate is combined with the amino acid after activation, then
By deprotecting base, the biomass adhesive using soybean protein isolate as major ingredient is obtained.Invention adhesive is to the gluing of timber
Intensity is high, water-tolerant, and hardening time is short.
Although biomass adhesive has gradually been used on cardboard or plank bonding, in flexible packaging industry, especially
It is gift box packaging field, because involved material category is more, more particularly to the bonding of a large amount of plastics, paper wood, cloth base material, and will
Certain open hour are asked, to water proofing property, anti-mildew are also required.Obviously, current biomass glue can not meet the need of the above
Will.
The content of the invention
