It can be directly used for making various tableware, cup, disk, film and package products, etc.

Description

Complete biodegradable thermoplastic starch resin
Technical field
The present invention relates to a kind of degradative resin, particularly relate to a kind of complete biodegradable thermoplastic starch resin.
Background technology
Plastics are one of most widely used materials, and a large amount of waste plastic products is made the face severe contamination to ecotope, and the development and application of degradative plastics is one of valid approach of this problem.What come into operation at present mainly is starch filled plastic and starch plastics, and starch content is low in these class degradative plasticss, is generally 10%~30%, and degradation property and poor mechanical property fundamentally do not solve " white pollution " problem.For overcoming above-mentioned deficiency, people begin starch plastics is carried out improved perfect, improve starch content and mechanical property in the goods.Chinese patent 1296988 discloses a kind of production method of biodegradable starch resin with high content of starch, its raw material comprises starch 65~75%, the attached thing of forming by polyvalent alcohol, polyprotonic acid and fatty cpd 25~35% of joining, ethylene-propylene copolymer 15~25%, and coupling agent, expanding material etc.Though this kind resin starch content is higher, but can not directly be used for making plastics, adding also needs to use with other processing characteristics, mixed with resin that mechanical property is good man-hour, could satisfy the processing characteristics and the mechanical property of plastics, so just greatly reduce contents of starch in the plastics, make that starch content only is about 35% in its plastics, only can partly degrade.Can not satisfy the effect requirement.
Summary of the invention
The object of the present invention is to provide a kind of starch content height, and good processability, the biodegradability excellence, and can directly be used for making the complete biodegradable thermoplastic starch resin of plastics.
The component of complete biodegradable thermoplastic starch resin of the present invention is by weight: starch 50.0~75.0, intermingling material A 5.0~20.0, intermingling material B 10.0~20.0, graft modification thing 1.0~5.0, chemical initiator 0.1~1.0, softening agent 2.0~10.0, coating 0.5~3.0, oxidation inhibitor 0.1~2.0.Wherein, intermingling material A is one or more in the thermoplastic resin, as polyethylene (PE), polypropylene (PP), polyethylene elastomer body (POE), α butene random copolymer (APA0) etc.Be mainly used in the thermoplasticity that improves material; Intermingling material B is one or more in cellulose family, polyvinyl alcohol (PVA), polyglycolic acid (PGA) class and polyester such as the polycaprolactone (PCL) etc.Be mainly used in the water resisting property and the biological degradability that improve material; The graft modification thing is one or more in long-chain unsaturated carboxylic acid and the ester class thereof, as hendecene base Succinic anhydried, dodecenylsuccinic acid ester, hendecene base Succinic anhydried, octadecenic acid etc.Be mainly used in the tensile strength that improves starch, elongation at break etc.; And fineness 〉=2000 orders of control starch, be generally 2000~3000 orders, can be W-Gum, wheat starch, pea starch, tapioca (flour) etc.; Chemical initiator is a kind of in the organo-peroxide, as dicumyl peroxide (DCP), benzoyl peroxide (BPO), ditertiary butyl peroxide ((DTBP) and lauroyl peroxide etc.Be used for causing the generation active centre; Softening agent is one or more in the polyol ester class.As adipic acid dibutylester, hexanodioic acid two (2-ethylhexyl) ester (DOA) dibutyl phthalate etc.; Coating is one or more in acid anhydrides or the organosilane ester.As maleic anhydride (MA), glycidyl methacrylate, titanic acid ester, phosphide ester etc., be used to eliminate the polarity and the crystallization of starch; Oxidation inhibitor is one or more in Hinered phenols or the hindered amines.As DI-tert-butylphenol compounds, 246,264, antioxidant A, antioxidant d, antioxidant A P, antioxidant H etc., prevent oxidation of starch in the processing.
The advantage of complete biodegradable thermoplastic starch resin of the present invention is the biological degradability excellence, and degraded has controllability, reduces environmental pollution, helps ecological environmental protection.Adopt combinatorial chemistry modification and crystalline region heat to melt processing, thoroughly eliminate the crystallization and the polarity of native starch, make its molecular structure realize randomization, improve starch thermoplastic resin performance and mechanical strength, and the technological process of production is brief, investment and production cost are low.Need not add other resin during use, improve contents of starch in the product, more help biological degradation, can be used for making all types of plastic goods, various tablewares, cup dish, film, packing bag, shopping bag etc.
