Abstract

The invention provides a bag-type low-odor automotive interior polypropylene material and a preparation method thereof.The bag-type low-odor automotive interior polypropylene material is prepared by blending, by weight, 10-30 parts of high-flow co-polypropylene, 25-80 parts of high-flow co-polypropylene, 10-30 parts of medium-flow co-polypropylene, 10-30 parts of medium-flow ethylene-octylene copolymer and 10-30 parts of talcum powder, and the high-flow co-polypropylene, the medium-flow ethylene-octylene copolymer, the talcum powder and the medium-flow ethylene-octylene copolymer are mixed. The high-fluidity ethylene-octylene copolymer air purifying material is prepared from the following components in parts by weight: 5-15 parts of high-fluidity ethylene-octylene copolymer, 5-30 parts of talcum powder, 0.5-1 part of toner, 0.05-0.2 part of main antioxidant, 0.05-0.2 part of auxiliary antioxidant, 1-2% of odor adsorbent and 7-9 parts of air purifying particles. The preparation method comprises the following steps: uniformly blending the components in a high-speed mixer, and extruding and granulating by a twin-screw extruder. The product prepared by the invention has the advantages of high flowability, odor of less than or equal to 3.7 grade in a high-temperature bag method, odor of less than or equal to 3.5 grade in a normal-temperature bag method, simple production process, easiness in processing and the like.

Description

technical field [0001] The invention belongs to the field of talcum powder-filled polypropylene materials, in particular to a bag-type low-odor automotive interior trim polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene has a wide range of sources, mature synthesis routes, and low prices. It is widely used in automobiles, home appliances, IT, OA and other fields, and is found in all aspects of human life. Because it is a thermoplastic material, polypropylene can be processed into parts of various shapes and structures after melt injection molding, so one of its most important uses is to apply it after being heated and melted by injection molding machines. [0003] Because polypropylene contains a special tertiary carbon structure, under the conditions of high temperature, high shear and oxygen, chain scission occurs and free radicals are formed, and free radicals trigger various chain reactions to produce small molecular weig...
