Thermoplastic anti-blocking agent and screening device for preparing thermoplastic anti-blocking agent

Abstract

The invention belongs to the technical field of polyethylene films, particularly relates to a thermoplastic anti-blocking agent and a screening device for preparation of the thermoplastic anti-blocking agent, and provides the following scheme aiming at the problems that the production cost is high due to the fact that preparation raw materials of an existing finished anti-blocking agent are expensive, and sorting is difficult to achieve when the raw materials are processed and screened. The screening device comprises a base, a processing box is fixedly installed on the top of the base, a first-stage screen, a second-stage screen and a third-stage screen are slidably connected into the processing box, and the first-stage screen, the second-stage screen and the third-stage screen with the hole diameters sequentially reduced are arranged. Carbon emission is avoided, and the preparation process is simple; and the anti-blocking agent is wide in source, low in price, suitable for multiple types of products and high in selectivity, and meanwhile, when the anti-blocking agent is processed and screened, the anti-blocking agent can be rapidly sorted, so that the anti-blocking agent screening device has good practicability.

Description

technical field [0001] The invention relates to the technical field of polyethylene film, in particular to a thermoplastic anti-blocking agent and a screening device for its preparation. Background technique [0002] In recent years, with the rapid development of the chemical industry, the rapid development of polyolefin, rubber and downstream sealing strips, hoses, tapes, automotive seals, and lubricant modification industries, the utilization rate of polyolefin and rubber in my country's industrial construction is increasing. high, and its demand is also increasing. With the rapid development of the downstream, the requirements for upstream polyolefin and rubber products are getting higher and higher. In order to improve the performance of polyolefin and rubber products in subsequent processing, it is necessary to add thermoplastic blocking agents to increase the market competitiveness of products. [0003] At present, the preparation of raw materials for the finished anti...

AI Technical Summary

Problems solved by technology

[0003] At present, the preparation of raw materials for the finished anti-aging agents on the market is relatively expensive, which makes the production cost higher, and it is difficult to realize sorting when processing and screening the raw materials, resulting in a longer production cycle in the production of anti-aging agents, resulting in higher processing costs. problem, so we propose a thermoplastic anti-blocking agent and a screening device for its preparation to solve the above-mentioned problems
