The method provided by the invention is simple and convenient; a made product is good in stability, is nontoxic and harmless, has no corrosiveness, is non-greasy and does not volatilize; the product does not show bioadhesiveness when moisture does not exist, quickly shows the adhesiveness to an organism once meeting water, and forms a uniform thin film within several seconds to cover a water surface; the thin film can last for as long as several months; if the thin film is agitated, a colloidal block mass with the adhesiveness is formed in water; the high molecular compound liquid colloid can be applied to the formation of an isolating film on the water surface, and is used for occasions of packing, the adhering of a micron-scale fine particle, the removal of oil contamination, hemostasis and the like.
Description
Technical field
The present invention relates to production and the applied technical field of a kind of colloidal materials, be directed to civilian, environmental protection, health, medical treatment, anti-smelting insect etc. multi-field.
Background technology
Existing film product is approved product, is membrane product when making, and membrane product does not separates or decomposes, and is unfavorable for extensively applying.
Silicon
Polymer and Oil Film investigated a kind of colloid, its can in water surface film forming, but they film forming speeds are slow, the film poor ductility of formation, the continuable time is short, is difficult to remove after film forming, to environmentally undesirable.
Summary of the invention
One of the object of the invention is that invention one meets that MJPZ is fast, the later stage removes easy polymer composite liquid colloid.
Polymer composite liquid colloid is mainly made up of polyvinyl acetate, propylene glycol, ethyl acetate, Dibutyl phthalate, n-butyl acetate, POLYSORBATE 80 and solvent；It is 2～80% that described polyvinyl acetate accounts for the mass ratio of complex liquid colloid；It is 0.2% that propylene glycol accounts for the mass ratio of complex liquid colloid；It is 0.1～5% that ethyl acetate accounts for the mass ratio of complex liquid colloid；It is 0.1～2% that Dibutyl phthalate accounts for the mass ratio of complex liquid colloid；It is 0.1～5% that n-butyl acetate accounts for the mass ratio of complex liquid colloid；It is 0.1% that POLYSORBATE 80 accounts for the mass ratio of complex liquid colloid.
The present invention is with polyvinyl acetate as macromolecular material, with propylene glycol and Dibutyl phthalate as plasticizer, with ethyl acetate as binding agent, with n-butyl acetate as cosolvent, with POLYSORBATE 80 as surfactant, above each raw material coexists in solvent, and forms the gel-like prod of mix homogeneously.The present invention is nontoxic, harmless, non-corrosiveness, and non-greasy is non-volatile；When not having moisture, product does not show bioadhesive, convenient long-term preservation, transport.But, after product once meets water, can quickly show biological adhesiveness, and within the several seconds, form the uniform thin film covering water surface, thin film can maintain the several months long, if be stirred thin film, i.e. forms the colloid agglomerate with adhesiveness in water.
It addition, solvent of the present invention can use the mixed liquor of acetone or acetone and ethanol, can regulate and control the viscosity of liquid colloid and control to meet the thickness of the thickness viscosity high film forming of MJPZ greatly, the thickness of viscosity low filming is little.
Further, polyvinyl acetate of the present invention accounts for the mass ratio of complex liquid colloid is 10～20%；It is 1% that ethyl acetate accounts for the mass ratio of complex liquid colloid；It is 0.5% that Dibutyl phthalate accounts for the mass ratio of complex liquid colloid；It is 0.9% that n-butyl acetate accounts for the mass ratio of complex liquid colloid；It is 7.7～97.5% that acetone accounts for the mass ratio of complex liquid colloid；It is 0～75% that ethanol accounts for the mass ratio of complex liquid colloid.The excellent results of the most each composition accounting is: thing liquid colloid viscosity is suitable, it is easy to sprays and uses.Film forming is rapid, and the thickness of film is suitable, has excellent elastic extensibility and persistency.
The ratio increasing organic solvent increases bioadhesive by prolonging and delays the formation of plastic films.
POLYSORBATE 80 makes the plastic films of final form more persistently in order to the elasticity and connection improving resin and plasticizer, the most even high resilience.
The two of the object of the invention are the preparation methoies proposing above polymer composite liquid colloid.
Method is: be dissolved in solvent by polyvinyl acetate, after 10～15 hours, adding propylene glycol, ethyl acetate, Dibutyl phthalate, n-butyl acetate and POLYSORBATE 80 while stirring, solubilizer is to volume required the most again, stirring, i.e. secure satisfactory grades sub-complex liquid colloid；When feeding intake, it is 2～80% that described polyvinyl acetate accounts for the mass ratio of complex liquid colloid；It is 0.2% that propylene glycol accounts for the mass ratio of complex liquid colloid；It is 0.1～5% that ethyl acetate accounts for the mass ratio of complex liquid colloid；It is 0.1～2% that Dibutyl phthalate accounts for the mass ratio of complex liquid colloid；It is 0.1～5% that n-butyl acetate accounts for the mass ratio of complex liquid colloid；It is 0.1% that POLYSORBATE 80 accounts for the mass ratio of complex liquid colloid.
The inventive method is simple, convenient, and the product stability made is good, it is simple to preserve.
The three of the object of the invention are to provide the purposes of polymer composite liquid colloid.
One of purposes: for forming isolating membrane on the water surface.
The two of purposes: after mixing with water, form the thin film for packaging.
The three of purposes: after mixing with water, sparge in air, are used for adhering to micron order fine particle.
The four of purposes: this polymer composite liquid colloid is formed bioadhesive agglomerate with degreaser bonding, is used for degreasing.
The five of purposes: be used for stopping blooding.
The present invention has convenient multiple use at multiple fields, introduces the most one by one.
Detailed description of the invention
One, polymer composite liquid colloid is prepared:
Being dissolved in solvent by polyvinyl acetate, after 10～15 hours, add propylene glycol, ethyl acetate, Dibutyl phthalate, n-butyl acetate and POLYSORBATE 80, the most again solubilizer while stirring, stir, i.e. secure satisfactory grades sub-complex liquid colloid.
