Abstract

The invention belongs to the technical field of modification and processing of high-molecular materials, and relates to a polypropylene composite material and a preparation method and an application thereof. The polypropylene composite material is prepared from the following components in parts by weight: 100 parts of polypropylene, 20-60 parts of reinforced fibers, 8-20 parts of polar additives, 10-35 parts of toughening agents, 1.5-3.5 parts of antiaging agents, 1.2-4.4 parts of compatilizer, 5-12 parts of inorganic composite fire retardants, 1.5-6.6 parts of smell inhibitors and 0.3-0.8 part of processing auxiliary agents. Compared with the prior art, the prepared polypropylene composite material is high in surface tension, achieves good bonding property with other materials, has the advantages of good rigidity without being lacked of toughness, good heat resistance, ageing resistance and fire retardance, little smell and excellent forming processing property and can be widely used as a special material for inner and outer ornaments of various types of automobiles.

Description

technical field [0001] The invention belongs to the technical field of polymer material modification and processing, and relates to a polypropylene composite material and its preparation method and application. Background technique [0002] Polypropylene material has been widely used in various automobile systems due to its good comprehensive performance. Most of the automotive exterior and interior parts are injection molded using polypropylene composite materials. Automotive interior parts such as dashboards, pillars, glove boxes, door panels, etc., exterior parts such as bumpers, anti-scratch strips, spoilers, etc. Bumper materials not only need good impact performance and processing performance, but also good paint adhesion performance. The bumper after paint spraying has a good appearance and produces a beautiful visual effect, but the bumper material after paint spraying needs to pass tests such as gasoline resistance, moisture resistance, water resistance and adhesi...
