Abstract

The invention discloses a toughening modified polyethylene powder and its preparation method. The toughening modified polyethylene powder comprises the following ingredients, by weight, 30-60% of polyethylene, 10-30% of ABS, 5-15% of glass fibre, 8-12% of a compound fire retardant, 3-10% of a flexibilizer, 1-3% of a styrene-maleic anhydride copolymer SMA, 0.1-0.5% of a 1010 antioxidant, 0.1-1% of EVA wax and 2-5% of antistatic master batch, wherein the ABS is an acrylonitrile-butadiene styrol copolymer with molecular weight being 80000-200000. The invention has beneficial effects as follows: the toughening modified polyethylene powder has advantages of excellent comprehensive properties, efficient flame retardance, good antistatic property and the like and has good practical value and prospect in fields of chemical industry, machine, tubing, packaging and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a toughened modified polyethylene powder and a preparation method thereof. Background technique [0002] Polyethylene is widely used due to its low price, easy processing and excellent corrosion resistance. However, polyethylene also has the defects of poor stress crack resistance, flammability, and insufficient heat resistance, which will greatly limit its application range. Contents of the invention [0003] The purpose of the present invention is to provide a toughened modified polyethylene powder with good impact toughness, strong wear resistance, good stress crack resistance and good flame retardancy and a preparation method thereof. [0004] The technical solution adopted by the present invention to solve the technical problem is: a toughened modified polyethylene powder, the components of which are proportioned by mass percentage: 30%-60% polyethylene, 10%-30%...
