Abstract
The invention discloses a low-density polyethylene (LDPE) transparent composite material for agricultural film and a preparation process for the LDPE transparent composite material. The LDPE transparent composite material comprises the following components in part by weight: 85 to 95 parts of anhydrous sodium sulfate, 5 to 15 parts of superfine talcpowder, 1 to 1.8 parts of surfactant, 3 to 8 parts of polyolefin elastomer (POE), 55 to 65 parts of linear low density polyethylene (LLDPE) and 1 to 3 parts of polyisobutene. The LEPE transparent composite material has high dispersibility, maintains the original longitudinal and transverse tension, and has great promotion value.
Description
Technical field
The present invention relates to the plastic material technical field, relate to a kind of LDPE 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.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, and toughness and rigidity can not well be unified, and can not keep original performance to pulling force in length and breadth.
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 LDPE agricultural mulching transparent composite of environment-friendly function.
Another object of the present invention provides a kind of preparation technology of LDPE agricultural mulching transparent composite.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of LDPE agricultural mulching transparent composite is characterized in that its component and part by weight umber ratio comprise:

POE 3-8 part
LLDPE 55-65 part
Polyisobutene 1-3 part.
As further specifying of such scheme: the component of said matrix material and part by weight umber are preferred:
90 parts of SODIUM SULPHATE ANHYDROUS 99PCTs
10 parts of superfine talcum powders
1.5 parts of surface treatment agents
5 parts of POE
60 parts of LLDPE
2 parts of polyisobutene.
A kind of preparation technology of LDPE 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 superfine talcum powder, 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 30 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.
