Description
Technical field
The present invention relates to a kind of medicinal flame retardant type plastic package material and preparation technology thereof, belong to acceptable packaging material technical field.
Background technology
The advantages such as polyethylene (PE) the plastics dielectric properties that density is little because having, intensity is high, corrosion-resistant, nontoxic and excellent, good chemical stability, anticorrosive, cheap, processing and forming is easy, are widely used in the industries such as chemical industry, food, medicine.But the rubbish that vinyon produces, owing to being not easily degraded, can destroying natural environment, cause high risks to environment, also result in serious threat to the existence of the mankind and various biology in landfill, burning disposal process simultaneously.Along with the reinforcement of mankind's environmental consciousness, various degradation plastic constantly occurs, degradation plastic, can disintegrate under bioenvironmental effect, to people or all harmless to environment, belongs to environmentally friendly environmentally friendly packing material.But at medical packaging Material Field, especially directly contacting in the acceptable packaging material of drug class, also do not use degradation plastic so far, the existing many degradation plastics commercially existed or studying can't meet the particular/special requirement of Key works Drug packing.
Polyethylene, owing to having inflammability, not only limits it and promotes the use of, and also brings potential safety hazard to producing and casting simultaneously.Therefore, improve polyethylene product performance, improve its anti-flammability, just become the major issue that we pay close attention to.Fire-retardant main method adds fire retardant and some fire proofing wherein, traditional flame resistant method is in system, add Halogen organic fire-retardant, and the non-halogen Main Means of fire retardant is then adopt phosphorus system, silicon system, nitrogen system, inorganic hydroxide etc. as fire proofing substantially.No matter be halogen containing flame-retardant, or bittern-free flame-proof material, all do not meet technical requirement and the quality requirement of the packaging material of directly contact medicine, thus cannot used as immediate packaging materials.Therefore, for Key works Drug packing, develop a kind of medicinal flame-retardant plastic packaging material and be extremely important.
Summary of the invention
The object of this invention is to provide a kind of medicinal flame retardant type plastic package material, both there is environmental protection, degradable, fire-retardant characteristic, meet again the requirement of directly contact drug class packaging material simultaneously; The present invention provides its preparation technology simultaneously.
Described medicinal flame retardant type plastic package material, comprises internal layer, intermediate layer, outer three-decker:
Be calculated in mass percent, internal layer is made up of following component:
Be calculated in mass percent, intermediate layer is made up of following component:
Be calculated in mass percent, skin is made up of following component:
Wherein, preferred technical scheme is as follows:
The PE of described internal layer is the mass ratio of LDPE and LLDPE, LDPE and LLDPE is 40 ~ 50:20 ~ 25.
The PE in described intermediate layer is the mass ratio of LDPE and LLDPE, LDPE and LLDPE is 30 ~ 40:20 ~ 30.
Described outer field PE is LDPE, LLDPE and mLLDPE, and the mass ratio of LDPE, LLDPE and mLLDPE is 25 ~ 30:20 ~ 25:15 ~ 20.
PHBV in described internal layer, intermediate layer and skin is the copolymer of 3-hydroxybutyrate ester and 3-hydroxyl valerate, and wherein the mass fraction of 3-hydroxyl valerate is 11%.
Described internal layer, outer field ECO are ethylenecarbon monoxide copolymer.
The EVA in described intermediate layer is ethylene-vinyl acetate resin, and wherein the mass fraction of vinyl acetate is 20%.
The preparation technology of described medicinal flame retardant type plastic package material, is first each component mixed according to formula ratio, then adopts three layers of inflation film manufacturing machine to carry out blown film, last rolling film forming or cut bag, and detailed process is as follows:
(1) start air-conditioner set: make the clean rank in workshop blown film district reach C level, bag district, Nei Bao district reach B level, during if any particular/special requirement, the clean rank in blown film district reaches B level, and bag district, Nei Bao district reach B+A level;
(2) clean area sterilization: carry out thorough disinfection by GMP requirement;
(3) air or nitrogen purge: air or nitrogen reach C level cleanliness factor standard after purification, during if any particular/special requirement, can reach B level or A level cleanliness factor standard;
(4) batch mixing: the raw material of formula ratio is mixed evenly;
(5) blown film: controlling barrel temperature is 170 ~ 190 DEG C, and die head temperature is 160 ~ 180 DEG C, and blow-up ratio is 2.0 ~ 3.5;
(6) rolling: rolling film forming respectively or cut bag as requested, the heat-sealing temperature cutting bag is 200 ~ 240 DEG C.
In the present invention:
PLA (PLA) is the linear biodegradated polymer materal of a kind of nontoxic, non-irritating polyesters, there is excellent biocompatibility, biodegradable and certain fire resistance, PLA is stable performance at normal temperatures, but in soil or water, can thoroughly resolve into water and carbon dioxide, can not pollute environment, the carbon dioxide that PLA combustion decomposition generates can dilute neighbouring oxygen, its surface also can form carburization zone simultaneously, thus plays fire-retardant effect.
The copolymer (PHBV) of 3-hydroxybutyrate ester and 3-hydroxyl valerate is a kind of starch is the Biopolvester that raw material is produced, its excellent combination property, can by bacterial digestion, carbon dioxide, water and living beings can be decomposed into completely under the natural conditions such as soil or compost, environmentally safe, decomposes the fire retardation that the carbon dioxide produced contributes to product.
Ethylenecarbon monoxide copolymer (ECO) is a kind of novel high polymer material of nontoxic, degradable, high-mechanical property, and under optical condition, degradable is carbon dioxide and water, do not pollute the environment, meanwhile, ECO has excellent fire resistance, and its fire-retardant rank is UL94V-0.
PLA and ECO, as the polymer substance simultaneously with fire retardation, can act synergistically, and the fire resistance with flammable PE series products is greatly enhanced, and fire-retardant rank can reach UL94V-2 or UL94V-1.
The shared system of ECO and PLA, PHBV, not only define the biodegradable systems of light-biological synthesis degradation-type, and define flame-retardant system, Synergistic degradation and fire retarding effect can be produced between ingredient in each system, environment-friendly degradable and fire-retardant two large specific functions are integrated in one, meet again the plastic package material requirement of country about " directly contacting drug packing material (container) standard " simultaneously, can be used as the environment friendly flame-retardant plastic package material for Key works Drug packing, this is one to medical packaging field and breaks through greatly.
Beneficial effect of the present invention is as follows:
(1) contained in the present invention biodegradable component, can be degraded rapidly by the microorganism in soil or rubbish and form large area cavity in a short time, make the mechanical properties decrease of material, thus splinter gradually, accelerate the degradation speed of material, achieve recycling economy.
(2) the present invention preferably coordinates according to the different performance of raw material, serve the effect of Synergistic, make material of the present invention can reach country to the quality requirement directly contacting drug class packaging material, there is again good environment-friendly degradable characteristic and flame-retarding characteristic simultaneously, fire-retardant rank is the highest can reach UL94V-1, relative to flammable polythene material, especially for the polyethylene kind drug packing material directly contacting medicine, be a kind of historical progress.
(3) for the production of medicine and packaging provide a kind of better, more high-quality, safer selection.
(4) broken away from and improved fire-retardant thinking by adding bittern-free flame-proof material or halogen containing flame-retardant, realized from a brand-new angle flame-retardant system being used for Key works Drug packing, started new pattern.
