Novel cleaning material for extruder screw and preparation method therefor

Abstract

he invention relates to a novel cleaning material for an extruder screw and a preparation method therefor. Preparation raw materials are composed of linear low density polyethylene LLDPE powder, low density polyethylene resin LDPE, diethylene glycol monobutyl ether, carbon tetrachloride, polyethylene glycol 400, ethanolamines, ethylene bis stearamide EBS, methyl vinyl silicon oil, calcium stearate, 10# white oil, polyethylene wax and talcum powder. The preparation method comprises the following steps: mixing at a high speed; and using a banburying and granulating method to prepare a plastic particle, wherein resin and burnt particles remaining inside an extruder can be instantly softened. According to the method, burnt carbide is softened by cutting molecular bonds of polymeric resin, and the adhesion between the resin and the extruder screw, a barrel and a mold is cut, so that a cleaning effect is achieved, only a small amount of the cleaning material is used, and the barrel is not damaged. The product comprises mutiple cleaning agents ingredients that can clean polyolefin materials of different hardness, and meanwhile, can be easily cleaned by other materials with relatively weaker hardness. Frequent use of the cleaning material can ensure safe operation of equipment and prolongs the service service of the extruder.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a novel cleaning material for an extruder screw and a preparation method thereof. Background technique [0002] At present, in the cable manufacturing industry, the cleaning of the cross-linked polyethylene extruder is a big problem. After extruding cross-linked cables for a long time and shutting down, it is necessary to clean and discharge the extruder to eliminate the problems caused by the long-term operation of the extruder. The scorched material produced and the material remaining in the hot runner of the extruder are used to ensure the normal operation of the extruder when it is restarted. At present, many enterprises still use polyethylene resin, waste materials, PVC materials, screw disassembly, fire and knife scraping to clean the extruder screw. This cleaning method cannot clean the screw and barrel hot runner, but will cause secondary pollution. If it is cleaned...

AI Technical Summary

Problems solved by technology

At present, many enterprises still use polyethylene resin, waste materials, PVC materials, screw disassembly, fire and knife scraping to clean the extruder screw. This cleaning method cannot clean the screw and barrel hot runner, but will cause secondary pollution

If it is cleaned with polyvinyl chloride material, it will also cause corrosion and pollution to the cross-linked pipeline

And after cleaning with the above method, it is still necessary to unload the die head and dismantle the screw, which is time-consuming, labor-intensive, laborious, and wastes a lot of resources, and at the same time causes great damage to the equipment.
