Special master batch for plastic weaving high-speed wire drawing machines and method for preparing special master batch

Abstract

The invention discloses special master batch for plastic weaving high-speed wire drawing machines. The special master batch comprises carrier resin, calcium carbonate, surface treating agents, dispersing agents, grinding additives and beta crystal form nucleating agents. A method for preparing the special master batch includes secondarily crushing the calcium carbonate and the grinding additives on a ring-roll micro-powder mill to obtain a semi-finished product; sequentially adding the surface treating agents, the dispersing agents, the beta crystal form nucleating agents and the carrier resin into a high-speed mixing machine and mixing the surface treating agents, the dispersing agents, the beta crystal form nucleating agents and the carrier resin with one another at a high speed to obtain mixtures; internally mixing the mixtures in an internal mixer to obtain materials; pouring the materials into a double-wrist (double-cone) feeding machine by the aid of a lift hopper, feeding the materials into a single-screw (double-screw) extruder by the aid of the double-wrist (double-cone) feeding machine and extruding and granulating the materials to obtain the special master batch. The special master batch for the plastic weaving high-speed wire drawing machines and the method have the advantages that the special master batch prepared by the aid of the method is good in dispersibility and flowability, high in tensile strength and easy to plasticize, accordingly, the cost of products can be lowered to a great extent, and the quality of the products can be enhanced.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a special masterbatch for a plastic braided high-speed wire drawing machine and a preparation method thereof. Background technique [0002] At present, China's plastic woven production has reached 70% of the world's production, accounting for more than 35% of China's PP consumption market, and it is the largest consumption variety and traditional industry in China's PP industry. Since 2013, my country's plastic woven industry has also implemented new plastic woven standards from the perspective of world technological development trends, technological innovation, and energy conservation and emission reduction, canceling the weight limit of woven bags and implementing lightweight. After the implementation of the new national standard, plastic knitting enterprises have focused on improving the strength of flat wire, and have not found a better technical solution to the problem of p...

AI Technical Summary

Problems solved by technology

However, the high-speed wire drawing machine has very strict requirements on the masterbatch. The original ordinary filler masterbatch is far from meeting the requirements of the high-speed wire drawing machine, and a series of problems have occurred, such as large dust, polluting the environment, poor dispersion, blockage of the machine head, and automatic replacement. High wire frequency, low tension of flat wire, low peeling strength, watery diaphragm, severe blade wear, poor flatness of woven bag, dull surface and other problems, the special masterbatch for high-speed wire drawing machine has not been matched in time
