Description
Technical field
The invention belongs to field of polymer technology, be specifically related to the blend and the moulding product of a kind of crystalline polymer and nucleator.
Background technology
In recent years, the consumption as the polyethylene of food, beverage-container, pallet etc. and commodity external packing box material, polypropylene, polyester, nylon etc. increases year by year.What accompany therewith is that the amount of using the back waste is also in continuous increase.Waste plastic class material is regarded as " white pollution " because of it is difficult to collect reclaim, it is very very long that reason is that the plastics back to nature finally incorporates microorganism round-robin process (being biological degradation), needed hundreds of years even more than one thousand years the puzzlement that a large amount of depleted plastics have brought " white pollution " because of its non-degradable.In causing environmental pollution all multifactor, the public hazards that plastic refuse causes have caused social extensive concern, and the development biodegradable plastic has become the task of top priority.
Biodegradable plastic comprises natural resin and synthetic resins, natural degradable plastics is to comprise natural resin and synthetic resins by renewable resources (for example starch) and by renewable thing degradative plastics, natural degradable plastics is that non-renewable synthesized degradable plastics are that the basis makes with petrochemicals by renewable resources (for example starch) and a kind of degradable high polymer material natural by renewable resources or that synthetic makes.The utilization biochemical technology, the technology of producing biodegradable plastic has both at home and abroad tended to ripe, has released the plastic prod of multiple complete biodegradable,
Therefore, Biodegradable material is in the field at center in agricultural aquatic products, civil engineering work, packing, container, daily necessities, health care, with the application that has more and more widely.For example, when being applied to food, beverage-container, pallet etc. and commodity external packing box, poly-succinic acid-butanediol fat needs to have certain hot patience at least, to prevent distortion that encased conveying or heating are brought and opaque etc.But the heat resisting temperature of biodegradable polyesters that with the poly(lactic acid) is representative is lower, is example with poly butylene succinate (PBS), and heat resisting temperature is not high, after poly butylene succinate is made the moulding product, use in case surpass certain temperature, will softening transform, thus influenced practical application.
By in biodegradable polyesters, adding the way of mineral filler, can improve the thermotolerance of poly butylene succinate to a certain extent.But only add mineral filler, can not guarantee sufficient hot patience.Therefore, again the someone propose in moulding/improve the thermotolerance of poly(lactic acid) by heat treated way after the moulding.Poly butylene succinate (PBS) is though have crystal structure, and crystallization is slow.If use the technological forming identical with ordinary resin, the moulding product are also keeping noncrystalline state, and mechanical property and thermotolerance all can not meet the demands.
Summary of the invention
The object of the present invention is to provide and a kind ofly compare easier crystalline with matrix poly butylene succinate (PBS), have a stable on heating biodegradable resin blend simultaneously.
Purpose of the present invention can reach by following measure:
A kind of resin blend, this blend is made up of a kind of crystalline polymer and a kind of amides, and wherein the consumption of crystalline polymer and amides (weight) is than being: 100: 0.1～100: 10.Wherein crystalline polymer is preferably the crystallinity polyester, further preferred aliphat biodegradable polyesters, most preferably poly butylene succinate.
Crystalline polymer among the present invention can be a polymkeric substance known, that have crystal structure: as polyester such as polyolefinss such as polypropylene, polyethylene terephthalate, polyamide polymers such as nylon.For the crystallinity polyester, mainly be meant crystalline polymer with at least more than one ester group, can be the straight chain shape, also can be dendritic.The crystallinity polyester preferably do not use petroleum resources, can natural degradation, can by natural resource manufacturings such as corn, reduce Carbon emission to prevent aliphatics biodegradable polyesters global warming, that have certain thermotolerance, formability.The aliphatics biodegradable polyesters can be poly-alpha hydroxy acid, poly-beta-hydroxy fatty acid, poly-ω-hydroxy fatty acid, poly-dicarboxylic acid alkylidene group diester etc., poly-alpha hydroxy acid such as preferred poly(lactic acid).Various biodegradable polyesters can prepare by known method.Specifically, can by the alcohol acid polycondensation; Methods such as diprotic acid and diacidic base polycondensation or cyclic monomer ring-opening polymerization prepare.The preferred linear polyester that obtains by aliphatic dibasic acid and aliphatic dihydroxy alcohol polymerization.The more preferably homopolymer of poly butylene succinate, multipolymer or the mixture between them.
But the polymkeric substance among the present invention does not limit to crystalline polymer above-mentioned, can also contain one or more of crystallinity such as Mierocrystalline cellulose, protein, polypeptide, amino acid and derivative thereof or non crystallized other biological degradable components.
Wherein amides is selected from one or more in the two alkylamides of ethylene, saturated fatty acid monoamide, unsaturated fatty acids monoamide or the amino acid amide, preferably one or more in lauric amide, stearic amide, amine hydroxybenzene, erucicamide, ricinolic acid acid amides, ethylene dilaurate acid amides, ethylene bis stearamide, the two amine hydroxybenzenes of ethylene, Methionin laurylamide, Methionin stearylamide, L-glutamic acid laurylamide, L-glutamic acid stearic amide, leucine propylhomoserin laurylamide, leucine stearylamide.
Blend method described in the present invention can be melt blending, mechanical blending etc. or their combination.Can realize by machineries such as high-speed mixer, single screw extrusion machine, twin screw extruder, Banbury mixeies.
A kind of moulding product, the thickness that resin blend of the present invention is obtained after fusion, moulding is the membranaceous or sheet material of 0.1～5mm.
Composition of the present invention not only than the easier crystallization of matrix poly butylene succinate, can also improve and guarantee the sufficient thermotolerance of poly butylene succinate, also have certain transparency simultaneously.
