Abstract
The invention discloses a high-wave-transparent reinforced polypropylene composition as well as a preparation method and application thereof. The high-wave-transparent reinforced polypropylene composition is prepared from the following components: polypropylene resin, chopped glass fibers, high-wave-transparent reinforced master batches and a toughening agent, wherein the high-wave-transparent reinforced master batch comprises polyamide resin, a dielectric filler, polytetrafluoroethylene and a compatilizer. According to the invention, the dielectric filler and polytetrafluoroethylene are compounded and blended in advance to prepare the high-wave-transparent reinforced master batch for polypropylene modification, and the prepared high-wave-transparent reinforced polypropylene composition has high wave transmissivity and low dielectric property, and also has high heat resistance and good comprehensive mechanical properties; the invention can be effectively applied to preparation of automobile interior and exterior.
Description
technical field [0001] The invention relates to the field of polymer materials and their molding processing, in particular to a high wave-transmitting reinforced polypropylene composition and its preparation method and application. Background technique [0002] Polypropylene material because of its low density (0.89 ~ 0.90g / cm 3 ), excellent mechanical properties, good stress resistance, yield resistance and chemical resistance, cheap price and easy recycling, etc., are widely used in the automotive field. With the development of automobile intelligence, more and more communication equipment and electronic equipment are used in automobiles, which further requires automobile materials to have better wave permeability and stable performance while ensuring their normal performance. signal propagation. [0003] At present, the reinforcement method of conventional polyolefin mainly uses fibers to achieve high strength and high rigidity, and improve the strength and heat resista...
