Abstract
The invention discloses a green and environment-friendly modified plastic which comprises the components in percentage by mass as follows: 28%-32% of polyhydroxyalkanoate, 28%-32% of polycaprolactone, 22%-25% of calcium carbonate, 10%-12% of starch, 3%-6% of a plasticizer and 2%-5% of a coupling agent. With the adoption of the scheme, strength, toughness, heat resistance and the like of a product can be improved, the production cost is reduced, recycling and reusing can be performed simultaneously, environment pollution is avoided, and new requirements of energy conservation, emission reduction and environment protection are met.
Description
Technical field
The present invention relates to plastic material field, particularly relate to a kind of environmental protection modified plastics.
Background technology
As everyone knows, common PP/PE plastics centuries under physical environment is all difficult to decompose.So plastic garbage is generally acknowledged people, it is the material of the highly polluting environment produced.Yet the purposes of plastics is but extensive especially, such as plastic toy, Plastic Bottle, plastic wrapping, plastics bag etc., we live and be unable to do without plastics at all.
Research discovery, polyhydroxyalkanoate (PHA) is polyester in the synthetic a kind of cell of a lot of microorganisms, is a kind of natural polymeric biomaterial.Because PHA has the hot workability of good physiologically acceptable performance, biodegradability and plastics simultaneously.Therefore can be used as bio-medical material and biodegradable wrapping material, in addition, PHA also has optically nonlinearity, piezoelectricity, a lot of high added value performances of being separated by property of gas, becomes the most active study hotspot of technical field of biological material in recent years simultaneously.
At present, both at home and abroad more common plastic prod is disposable cup, knife and fork, plate, plastics bag, non-woven fabrics etc., in theory so long as plastics can make of this biological plastics material.Yet because its production cost is higher, and toughness is poor, resistance toheat is not high yet, is not used widely always.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of environmental protection modified plastics, intensity, toughness and the resistance toheat etc. that can improve product, reduce production costs, and recycling can circulate simultaneously, environmentally safe, reaches the new demand of energy-saving and emission-reduction, green, environmental protection.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of environmental protection modified plastics is provided, comprises the following ingredients forming by mass percentage:
Polyhydroxyalkanoate 28%-32%,
Polycaprolactone 28%-32%,
Calcium carbonate 22%-25%,

Coupling agent 2%-5%.
In a preferred embodiment of the present invention, comprise the following ingredients forming by mass percentage:
Polyhydroxyalkanoate 30%,
Polycaprolactone 30%,
Calcium carbonate 25%,
Starch 10%,
Softening agent 3%,
Coupling agent 2%.
In a preferred embodiment of the present invention, comprise the following ingredients forming by mass percentage:
Polyhydroxyalkanoate 32%,
Polycaprolactone 28%,
