Abstract
The invention discloses a transparent starch-based degradable agricultural mulching film composite material and a preparation process thereof. The composite material is characterized by comprising the following components in parts by weight: 85-95 parts of anhydrous sodium sulfate, 18-33 parts of corn starch, 1-1.8 parts of surface treating agent, 3-8 parts of polyolefin elastomer (POE), 55-65 parts of linear low density polyethylene (LLDPE) and 1-3 parts of polyisobutylene. The composite material disclosed by the invention has good dispersibility, maintains the original longitudinal and lateral tension properties, and has good promotion value.
Description
Technical field
The present invention relates to the plastic material technical field, relate to a kind of starch-based agricultural mulching transparent composite and preparation technology thereof in particular.
Background technology
New LDPE (film grade) degree Vilaterm (LDPE) is a kind of plastic material, and it is fit to the various moulding processs of thermoplastic molding's processing, and forming process property is good.The LDPE main application is to make film product, also is used for injection-molded item, medical apparatus, medicine and packaging material for food, blowing slush molding goods.Linear low density polyethylene (LLDPE); Be that ethene and a small amount of high alpha-olefin (like butene-1, hexene-1, octene-1, tetramethyl-amylene-1 etc.) are under catalyst action; Through a kind of multipolymer that high pressure or low-pressure polymerization form, density is between 0.915～0.940 gram/cubic centimetre.At present, traditional LDPE exists anti-environment capacity poor, and especially resistance to elevated temperatures is poor; Be used under the agricultural mulching surrounding medium and be easy to brittle cracking, and shrinking percentage is big, toughness and rigidity can not well be unified; Can not keep original performance to pulling force in length and breadth, can not degrade, not meet environmental requirement.
Summary of the invention
The object of the invention is exactly a kind of not only good dispersibility that provides for the deficiency that solves prior art, keeps original performance to pulling force in length and breadth, and has the starch-based degradable agricultural mulching transparent composite of environment-friendly function.
Another object of the present invention provides a kind of preparation technology of starch-based degradable agricultural mulching transparent composite.

Said surface treatment agent is dedicated modified dose an of starch.
A kind of preparation technology of starch-based degradable agricultural mulching transparent composite is characterized in that it comprises the steps:
A, elder generation are added in horizontal double helical ribbon mixer with SODIUM SULPHATE ANHYDROUS 99PCT and W-Gum, and the heating middling speed was mixed 25-35 minute;
B, add surface treatment agent, mixed at high speed 10-20 minute;
C, add POE and LLDPE, mixed at high speed 8-15 minute;
D, through the screw rod feeder, the mass transport that mixes is to continuous Banbury mixer material storage tank;
E, through the powder metering feeding machine, feeding is to continuous Banbury mixer;
F, polyisobutene is added to the liquid meter feeding machine, feeding is to continuous Banbury mixer;
G, extruding pelletization;
E, finished product packing.
In said process step a process, said mixed powder water cut < 2%, mixed 20 minutes by the heating middling speed.
In the mixed at high speed process of said process step b, mixed at high speed 15 minutes, treatment agent is wanted complete coated powder.
In said process step c process, mixed at high speed 10 minutes.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, matrix material of the present invention is pressed original LDPE production technique on the blown film machine, fully ordinary production.
2, good dispersibility keeps original performance to pulling force in length and breadth.
3, reach environment-friendly function.
