Problems solved by technology

[0002] Polyethylene talcum powder masterbatch is a kind of plastic modified filler, which refers to the granules formed by mixing and granulating the main component of talc powder with polymers or other carriers. It is mainly used to improve the properties of rubber, plastic resins, etc. Improve the stiffness, high temperature creep resistance, heat resistance and other properties of the filling material; but the existing polyethylene talcum powder masterbatch cannot effectively improve the dispersion of plastics; and the thermal stability is not good

Abstract

The invention discloses a polyethylene talcum powder master batch. The polyethylene talcum powder master batch is prepared from, by weight, 19.5-20.5% of polyethylene, 0.1-1.1% of polyethylene wax and 78.9-79.9% of talcum powder. During preparation, talcum powder is put at first, polyethylene is added, then, the polyethylene wax is added, the mixture is subjected to smelting to be heated to 150 min, heating is performed for 12 min, then, the mixture enters a double-screw extruder to be mixed, mixing is performed, and then extruding, cooling and grain dicing are performed. In this way, the polyethylene talcum powder master batch is applicable to plastic modification, and due to the compact form and the higher compound quantity, the plastic is good in dispersity, resistant to wear and scraping, capable of achieving feeding easily and good in heat stability.

Description

technical field [0001] The invention relates to the field of plastic materials, in particular to a plastic material that is very suitable for plastic modification. Due to its compacted form and higher compounding amount, the plastic has good dispersion, wear resistance, scratch resistance, and easy feeding. , Polyethylene talcum powder masterbatch with good thermal stability. Background technique [0002] Polyethylene talcum powder masterbatch is a kind of plastic modified filler, which refers to the granules formed by mixing and granulating the main component of talc powder with polymers or other carriers. It is mainly used to improve the properties of rubber, plastic resins, etc. Improve the stiffness, high temperature creep resistance, heat resistance and other properties of the filling material; but the existing polyethylene talcum powder masterbatch cannot effectively improve the dispersion of plastics; and the thermal stability is not good.
