Abstract

The invention relates to a filling master-batch, a polyethylene modified film adopting the filling master-batch, and a production method thereof. The filling master-batch comprises the components of, by weight, 3-7 parts of LDPE, 3-7 parts of LLDPE, 1-3 parts of a coupling agent, 600-1200 parts of stone powder, and 2-10 parts of paraffin. The filling master-batch has the following advantages: (1) the low-density polyethylene material is adopted, such that the master-batch is water-resistant, flame-resistant, ultraviolet-resistant, wear-resistant, durable, degradable, green and environment-friendly, and pollution-free; the master-batch has lower cost, better performance, and stable structure; (2) the cost of the filling master-batch provided by the invention is 2500yuan / ton, and the cost of a polyethylene raw material is 11000yuan / ton, such that polyethylene modified film cost is greatly reduced, and the tensile property of the film is not changed; (3) the production method provided by the invention is simple and easy to operate; the entire production process has no three-waste pollution and no emission. The method has significant economical and social benefit.

Description

technical field [0001] The invention relates to a filling masterbatch, a polyethylene modified film using the masterbatch and a production method, and belongs to the technical field of agricultural tarpaulins. Background technique [0002] Tarpaulin is a widely used product. The traditional plastic tarpaulin used as a cover is mainly made of chemical fiber woven cloth dipped or cast and compounded with a layer of film as the base material. [0003] It is widely used in industrial industries, including covering objects, vehicles, tourist tents, decoration, temporary facilities on construction sites, and tarpaulins for geotechnical processes. This single-sided or double-sided laminated woven fabric laminated tarpaulin has a lower cost and has a wide range of uses. However, because this kind of tarpaulin is made of plastic woven cloth as the base material, the production cost, labor cost and processing cost of the woven cloth are easy to increase rapidly, resulting in a rapid ...
