Description

A kind of waterproof degradation environment protection bag
Technical field
The present invention relates to polybag technical fields, more particularly to a kind of waterproof degradation environment protection bag.
Background technique
A large amount of uses of plastics produce many irretrievable disposable plastic waste products, cause and get worse " white pollution " seriously endangers the existence of the mankind and is good for if body of groundwater pollution and soil pollution, animal and plant resource are destroyed Health.Starch has regeneration, cheap, easy to maintain and the characteristics of be readily transported, and can carry out various reactions under certain condition, derive Numerous derivatives.And the good reproducible utilization of starch and biological degradability become the fabulous original of biodegradation material Material.Although starch plastic goods cost is 10-30% higher than general plastics at present, with it is production-scale expansion and its technology into Step, uses starch to have very big development potentiality as raw material next life generation degradation products to substitute partly plastic product.
Polyhydroxyalkanoates has excellent biocompatibility and absorbability, nontoxic, non-stimulated, it is in nature It can be decomposed completely under the effects of microorganism, water, acid, alkali, final product is CO2And H2O, no pollution to the environment can be used as environmentally friendly material Material replaces traditional polymer material, and polyhydroxyalkanoates plastics are although degradable at present, but that there is also waterproof performances is insufficient Technical problem.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of waterproof degradation environment protection bags, can be complete Degradation, does not cause white pollution, not only good water-proof effect, but also mechanical property is good, toughness is balanced with hardness, good toughness, anti-impact Hit intensity is high.
The waterproof degradation environment protection bag of one kind proposed by the present invention, raw material include: cornstarch 40-50 by weight Part, 15-28 parts of polyhydroxyalkanoates, 2-8 parts of polyurethane resin, 2-10 parts of stearyl methacrylate, 3-7 parts of plasticizer, 1-2 parts of disproportionated rosin, 0.1-0.6 parts of penylene bismaleimide between N, N'-, 30-40 parts of filler, butyl titanate 0.2-1 Part, 1-2 parts of UV absorbers UV-531.
Preferably, plasticizer includes: polyvinyl alcohol, pentaerythrite.
Preferably, polyvinyl alcohol, pentaerythrite weight ratio be 1-4:1-3.
