Abstract
The present invention is degradable plastic film of a kind of environmental protection and preparation method thereof, and its raw material composition is：20 28 parts of polypropylene；38 parts of polyvinyl chloride；0.3 0.9 parts of propane diols；18 25 parts of polytrimethylene terephthalates；10 22 parts of dioctyl phthalates；37 parts of hydrotalcites；12 portions of nucleators；22 25 parts of plant fiber starch；26 parts of antioxidants 168.Its preparation process is that above-mentioned raw materials are added in batch mixer；Then traction cutting, winding, the degradable plastic film of environmental protection is produced.It is simple that the present invention provides the plastic film technique prepared, by adding dioctyl phthalate, polytrimethylene terephthalate and nucleator, improve the shock resistance of plastic film, addition plant fiber starch make it that plastic film can natural degradation, it effectively prevent because recovery is difficult, the pollution brought to environment, expand the application of plastic film.
Description
Technical field
The present invention relates to plastic film technical field, more particularly to a kind of degradable plastic film of environmental protection and
Its preparation method.
Background technology
Plastic film is a kind of good packaging material, by plastic film make polybag have it is light, thin,
Waterproof, the advantages of intensity is big, cost is low, it is widely used in the fields such as food, medicine, chemical industry.However, a large amount of at present use
Most of plastic film shock resistance to be present poor, it is not degradable, cause recovery difficult, brought to a certain degree to environment
Pollution, seriously limit the use of plastic film.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of degradable plastic film of environmental protection and its system are provided
Preparation Method.
The present invention to achieve the above object, using following technical scheme：A kind of degradable plastic film of environmental protection, its
It is characterised by, is made up of the raw material of following parts by weight：
Particularly, described nucleator is Pioloform, polyvinyl acetal.
A kind of preparation method of the degradable plastic film of environmental protection provided by the invention, it is characterised in that including with
Lower step：
(1) by polypropylene, polyvinyl chloride, propane diols, polytrimethylene terephthalate, dioctyl phthalate, neatly
Stone, nucleator, plant fiber starch and antioxidant 168 are added in batch mixer by the raw material of above-mentioned parts by weight to be mixed, and is added
Heat is warming up to 100-108 DEG C, stirs 15 minutes；
(2) said mixture material is sent into extruder fusing extrusion, melting temperature is 150-160 DEG C, then carries out die head and blow
Film is shaped, and die head temperature is controlled at 170-180 DEG C, then traction cutting, winding, and it is thin to produce the degradable plastics package of environmental protection
Film.
The beneficial effects of the invention are as follows：The plastic film technique that the present invention provides preparation is simple, by adding adjacent benzene
Diformazan dioctyl phthalate, polytrimethylene terephthalate and nucleator, on the premise of film strength is ensured have higher elasticity and
Wrinkle resistance, and then the shock resistance of plastic film is improved, by adding plant fiber starch, can effectively facilitate poly-
The biodegradation of propylene and polyvinyl chloride so that plastic film can natural degradation, it is environment friendly and pollution-free, effectively prevent because return
Difficult, the pollution brought to environment is received, expands the application of plastic film.
