Description
Technical field
The invention belongs to degradation material preparing technical field, and in particular to a kind of starch base applied to packaging for foodstuff is given birth to
The preparation method of Biodegradable plastics.
Background technology
The high speed development of Plastics Industry brings great convenience to the production and living of people, but is caused by plastic refuse
" white pollution " problem also getting worse, the problem of environmental pollution that the plastics of difficult degradation trigger is increasingly by countries in the world
Concern and attention, it is a fundamental way for solving plastic pollution using degradation plastic.Solves modeling seeking degradation plastic
Expect the research process of refuse pollution, the degradation plastic that raw material obtains based on starch has obtained rapid development.Can
In degradative plastics, this natural high molecular substance of starch has wide material sources, cheap, the regeneration period is short, can be in a variety of rings
It is degradable under border, will not to environment produce any pollution the advantages that, be the good Natural Degradation material of development prospect.Starch base
Material is widely developed into degradable packaging material, disposable tableware, film and refuse bag etc..Wherein starch is set with synthesis
Fat or other natural polymer blended starch materials formed, it is currently commercially exploitation degradative plastics the most successful.
The Mater-Bi plastic series product of Italian Novamont companies just belongs to starch-based material product.Mater-
The product of Bi-A levels is to form physical cross-linked network of the continuous ethylene-vinyl alcohol copolymer (EVOH) mutually with starch phase
High polymer alloy, but this series of products cost is too high, it is difficult to a wide range of industrialization, the marketization.German BIOTEC companies research and development
With biological degradation plastics of the production using starch and aliphatic polyester as primary raw material, wherein the content of starch 55%~
Between 75%, the product mechanical property, hot property etc. are poor.And the domestic research to the starch plastic of fully biodegradable is more
Rest on basic research or laboratory stage.
The poor-performings such as the machinery of starch base degradable plastic, mechanics, are very limited in actual applications.The present invention
Starch, string, the synthesis content of poly butylene succinate reach as high as in the Starch Based Biodegradable Plastics of preparation
80%, the non-renewable resources such as oil, every hygienic physical and chemical index can be saved with natural degradation under soil and natural environment
National standard is can reach, is generally to use debatable " non-degradable packaging material for food " in current catering market
Ideal substitute.The technical problems to be solved by the invention are to be directed to above-mentioned the deficiencies in the prior art, there is provided one kind is applied to
The preparation method of the Starch Based Biodegradable Plastics of packaging for foodstuff.The Starch Based Biodegradable Plastics prepared using this method
Tensile strength, impact flexibility, elongation at break and the tearing strength of degradation plastic are improved, improves the physical of material
Can, practicality is added, it is all significant in environmental protection and development of resources etc..
The content of the invention
The present invention overcomes deficiency of the prior art, there is provided a kind of cost is low, reasonable mixture ratio, and mechanical property is good, during degraded
Between short degradation plastic.In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
By weight, formula is as follows for its raw material components：Starch 50-60 parts, polypropylene 18-26 parts, poly butylene succinate 6-
