Abstract

The invention discloses a polyolefin rheological master batch-PPA and a preparation method thereof. The polyolefin rheological master batch-PPA is prepared from the following raw materials in parts by mass: 91 to 93 parts of linear polyethylene powder, 3 to 5 parts of polyphthalamide, 0.2 to 0.3 part of a composite antioxidant, 1 to 2 parts of polyethylene paraffin and 0.5 to 1 part of paraffin. The extrusion processing technology range of the polyolefin resin can be widened; the polyolefin resin is suitable for various slipping agents, pigments and other inorganic additives; melt rupture is reduced or eliminated; opening film accumulated materials are reduced or eliminated; the apparent melt viscosity is reduced; the effective concentration is low; the product is in the form of flowing particles; the processing performance is improved, the cost is reduced, and the product strength and quality are improved; by improving the extrusion process, the extrusion yield is increased, and the bidirectional physical properties, transparency and surface gloss of the film are improved.

Description

technical field [0001] The invention relates to the field of pure natural compositions with the function of reducing fat and losing weight, in particular to a polyolefin rheological masterbatch—PPA and a preparation method thereof. Background technique [0002] Polyolefin, due to abundant raw materials, low price, easy processing and molding, and excellent comprehensive performance, is a kind of polymer material with the largest output and wide application. Among them, polyethylene and polypropylene are the most important. The main varieties are polyethylene and some copolymers based on ethylene, such as ethylene-vinyl acetate copolymer, ethylene-acrylic acid or acrylate copolymer, as well as polypropylene and some propylene copolymers, poly1-butene, poly 4-Methyl-1-pentene, cycloolefin polymer. [0003] Polyolefin films are usually made of polypropylene PP and polyethylene PE, and the existing polyolefin films are prone to film accumulation, insufficient fluidity of mater...
