Abstract

The invention belongs to agricultural film manufacturing fields, and in particular to a kind of calcium sulfate opening masterbatch and preparation method thereof.Each component and mass percent are as follows: low density polyethylene (LDPE) powder LLDPE 89~91%, commercially available calcium sulfate opening agent 7.9~8.1%, composite antioxidant 0.09~0.11%, paraffin oil 1.9~2.1%.Electronic scale accurately weighs various components, then launches in high-speed mixer, closing feed bin upper cover, and mixed at high speed 1~3 minute；It is sent into double screw extruder after the completion of mixing, is formed by mouth mold, formed through pelleter pelletizing so that material sufficiently carries out plasticizing and uniformly mixing by pressure and shearing force that screw rod rotation generates, cyclone separator dehumidifying, output finished product.Product of the invention can be effectively reduced the frictional resistance in film manufacturing processes, reduce film bubble panting, and product opening is functional, meets expected design, meets film production.

Description

A kind of calcium sulfate opening masterbatch and preparation method thereof
Technical field
The invention belongs to agricultural film manufacturing fields, and in particular to a kind of calcium sulfate opening masterbatch and preparation method thereof.
Background technique
In process of production, to prevent film article to be sticked together, opening is difficult for plastic film, and certain amount need to be added Opening masterbatch.It is open there are many kinds of masterbatch markets, including the opening such as use grease type, mineral substance, talcum powder class, silica Agent is made.Mesh is typically chosen when being used as production opening masterbatch using grease type, mineral substance, talcum powder class, silica etc. The big micro mist of number, these relatively common problems are exactly that micro mist shape additive amount is high, have a certain impact for film clarity.Have Opening agent density it is low, expansion broken strip is easy when production, production efficiency is low.
Summary of the invention
The purpose of the present invention is to provide a kind of calcium sulfate opening masterbatch and preparation method thereof.Specific technical solution is as follows；
Calcium sulfate opening masterbatch selects good type low density polyethylene resin, paraffin oil, calcium sulfate, antioxidant etc., Using mixed at high speed and the processing technology of twin-screw extrusion when production, by Adjustment Tests repeatedly, be finally reached one it is optimal Matching ratio meets the various functions of product.
One, calcium sulfate opening masterbatch factory formula
The mass percentage composition of calcium sulfate opening masterbatch are as follows:
Low density polyethylene (LDPE) powder (LLDPE) 89~91%, commercially available calcium sulfate opening agent 7.9~8.1%, compound antioxygen Agent 0.09~0.11%, paraffin oil 1.9~2.1%.
Two, the preparation method of calcium sulfate opening masterbatch
According to formula, electronic scale accurately weighs various auxiliary agents.Then it launches in high-speed mixer, closes on feed bin Lid, mixed at high speed 1~3 minute.It is sent into double screw extruder after the completion of mixing, the pressure and shearing generated by screw rod rotation Power can allow material sufficiently to carry out plasticizing and uniformly mixing, be formed, be formed through pelleter pelletizing, whirlwind by mouth mold Separator dehumidifying, output finished product.
Beneficial effects of the present invention
The present invention is different from the opening masterbatch of other types, using calcium sulfate class opening agent.This product is added to film In can not only improve its processing performance, prevent film blocking, and can be improved the transparency of product.Product energy of the invention The frictional resistance in film manufacturing processes is enough effectively reduced, reduces film bubble panting, product opening is functional, and it is pre- to meet design Phase meets film production.
Detailed description of the invention
Fig. 1 is the preparation flow figure of calcium sulfate class of the present invention opening masterbatch.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
Embodiment 1
The preparation of calcium sulfate opening masterbatch:
Low density polyethylene (LDPE) powder (LLDPE): 90kg
Commercially available calcium sulfate opening agent: 8kg
Composite antioxidant (B215): 0.1kg
Paraffin oil (150): 1.9kg
By the above components precise, put into high-speed mixer and stir, be granulated through double screw extruder, output at Product.
