Description
Technical field
The present invention relates to the preparations of a kind of degradation material and its application and hollow container in preparing hollow container
Method and preparation facilities.
Background technology
Existing plastic products such as hollow container mostly use machine-shaping be easy, the higher polyolefin tree of heat decomposition temperature
Fat (such as polyvinyl chloride, polyethylene, polypropylene) is made as raw material, although vistanex is a kind of with fastest developing speed, kind
At most, the maximum resin of yield, but vistanex is not degradable, for containing pesticide, medicine, makeup etc., these are hollow
Container is difficult to handle after discarded, fills the environmental pollution because it cannot degrade then caused by, burning then generate a large amount of two evils because and it is toxic
Gas, for this purpose, many researchers are dedicated to the research and preparation of some biodegradable resins, Biodegradable resin mainly by
Natural polymer such as starch or agricultural and sideline product are made through the macromolecule of microbial fermentation or synthesis with biological degradability, such as thermoplastic
Property starch-resin, aliphatic polyester, polylactic acid, starch/polyethylene alcohol etc. belong to this resinoid, since Biodegradable resin has
Excellent performance, it is discarded after can be decomposed completely by environmental microorganism, finally become carbon in nature by inorganization and follow
One component part of ring, therefore with the development of society, the product of Biodegradable resin will necessarily replace us to use at present
The petroleum base resin product for being difficult to degrade.However, in the preparation process of traditional Biodegradable resin, use mostly
The starch (such as cornstarch) of staple food grain crop is used as primary raw material, and Biodegradable resin is prepared using the starch of staple food grain crop,
There is striving grain with people, in addition, most Biodegradable resin is acidproof, alkaline-resisting, anticorrosion, pollution-proof performance are not excellent enough
It is different, it is unsuitable for the preparation of an a little hollow container with corrosion resistance.In summary, it is necessary to develop a kind of degradable
Material, the degradation material can be used for the preparation of hollow container, also need to design accordingly it is a kind of with the degradation material come
Prepare the preparation method and preparation facilities of hollow container.
