Abstract

The invention provides a high filling polyethylene blend modifier and a preparation method thereof and an application in papers, three dimensional (3D) printing and packaging materials, wherein the high filling polyethylene blend modifier comprises following raw materials with parts by weight: polyethylene 15-35 parts, inorganic fillers 60-80 parts, hyperbranched polymer 0.5-2 part, coupling reagent 1.2-1.7 parts and lubricant 2-5 parts. The high filling polyethylene blend modifier and the preparation method thereof and the application in papers, three dimensional (3D) printing and packaging materials are simple in process and simple and convenient in operation, achieve filler content in high filling polyethylene blend modifier to be above 60%, enable filters to uniformly disperse, are smooth in surface, and have excellent melt flowability.

Description

(1) Technical field [0001] The invention relates to polymer filling modification technology, in particular to a highly filled polyethylene blend modification and its preparation method and application. (2) Background technology [0002] The research on polymer filling modification technology has a long history. The original purpose of filling modification is to increase and reduce costs, and now it has been developed to strengthen and toughen the matrix resin, improve the technical content of the product, endow it with unique properties and functions, and increase its added value. Highly filled modified polyolefin materials are widely used in polyolefin films, woven bags, packing tapes, pipes, sheets and injection molding, automotive and household appliance parts. In addition, high-filling polyethylene contains a large amount of inorganic fillers, which can improve the degradability of filling materials due to the dissolution of inorganic substances in the soil. High-filli...
