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 technology, and relates to a polypropylene composite material and its preparation method and use. Background technique [0002] Due to its good comprehensive properties, polypropylene materials have been widely used in major automotive systems. Most automotive exterior and interior parts are injection molded using polypropylene composite materials. Car interior parts such as instrument panels, pillars, glove boxes, door panels, etc., and exterior parts such as bumpers, anti-scratch strips, spoilers, etc. Bumper materials not only require good impact properties and processing properties, but also require good paint adhesion properties. The paint-sprayed bumper has a good appearance and produces a beautiful visual effect, but the paint-sprayed bumper material needs to pass tests for gasoline resistance, moisture resistance, water resistance and adhesion. If th...
