Description
Technical field
The present invention relates to plastic formula technical field more particularly to a kind of degradable plastic material formulas.
Background technique
Plastics are to pass through high-molecular compound made of addition polymerization or polycondensation polymerized using monomer as raw material
(macromolecules), it is commonly called as plastics (plastics) or resin (resin), can freely change ingredient and body styles,
Be made of the additives such as synthetic resin and filler, plasticizer, stabilizer, lubricant, colorant, plastics because of its excellent performance
Gradually used by various fields.
Plastic products made by traditional plastics are not mostly degradable, such as the plastic film in farmland and greenhouse, when
For plastic products after especially Phthalates are dropped, its own nondegradable characteristic can bring very big dirt to environment
Dye, at the same time, petroleum resources necessary to prepared by conventional plastic also have become world's resource in short supply, we design thus
A kind of degradable plastic material formula solves problem above.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of degradation plastic proposed is matched
Side.
To achieve the goals above, present invention employs following technical solutions:
A kind of degradable plastic material formula, the raw material including following parts by weight: 40~70 parts of starch, Film grade polyethylene 30~70
Part, 10~20 parts of polylactic acid, 1~20 part of plasticizer and 0.5~1.5 part of heat stabilizer.
Preferably, the raw material including following parts by weight: 55 parts of starch, 60 parts of Film grade polyethylene, 16 parts of polylactic acid, plasticising
14 parts and 1 part of heat stabilizer of agent.
Preferably, the starch is plant fiber starch.
Preferably, the plasticizer selects one of mineral oil, urea, formamide.
Preferably, the heat stabilizer is triphenyl phosphite.
Preferably, formula is prepared into the technique of plastics and includes the following steps,
S1, stock: according to parts by weight than weighing the raw material of each component, including 40~70 parts of starch, Film grade polyethylene 30
~70 parts, 10~20 parts of polylactic acid, 1~20 part of plasticizer and 0.5~1.5 part of heat stabilizer；
S2, mixing: the raw material in S1, which is added in clamping plate container, to be mixed, and after being sufficiently mixed, obtains premix；
Granulation: S3 the premix in S2 is put into the feed bin of granulator and is pelletized, and is screened to particle obtained
Afterwards, it carries out storing spare；
Film forming: S4 the master batch after screening in S3 is put into bolt extruder and carries out blown film, and is wound, plastic film is obtained；
S5, quality inspection storage: to plastic film obtained in S4 carry out performance detection, then according to specification be packaged into
Library.
Preferably, before the raw material that each component is weighed in the S1, quality testing and removal of impurities are carried out to each component.
Compared with prior art, the beneficial effects of the present invention are:
1, for the present invention using plant amylum as raw material, acquisition is convenient, at low cost and degradable, component polylactic acid it is main
Raw material is corn, can further increase the degradability of plastics after addition, and polylactic acid have good tensile strength and
Extensibility, easy processing, and manufactured film have good glossiness and transparency；
2, each component is simple, low in cost in the present invention, and processing technology is simple, high financial profit, is suitable for batch production.
