Abstract

The invention relates to a foaming polypropylene composition. In the foaming polypropylene composition, a polypropylene component is used as a substrate material, a hindered phenol antioxygen and a phosphite ester antioxygen form an antioxygen system, talcpowder or calcium carbonate is used as a nucleating agent and monoglyceride is used as an activator. The composition disclosed by the invention has the characteristics of simple and stable preparation process, high processing performance and the like; and the density of the high-power foamed product formed by extruding the composition is controllable within a range from 18 to 100kg/m<3>, the maximum foaming power can reach 50 times, and the foaming polypropylene composition has the characteristics of closed pore structure, fine and uniform foam pore size, and the like. The polypropylene high-power foamed product has the characteristics of high comprehensive mechanical performance, high energy absorbing and buffering effect, environment friendliness, easy recycling and the like and can be used in fields of automobiles, high-quality electronic packages, buildings and the like with energy-saving and environment-protection effects and other effects.

Description

technical field [0001] The invention relates to a foaming polypropylene composition, which can be extruded and foamed to obtain a high-magnification polypropylene foaming material, which can be used in industries such as automobiles, construction, high-end electronic packaging, food packaging, etc. Partially replace polyethylene and polystyrene foam materials. Background technique [0002] Polypropylene foaming material is a new generation of foaming material following the traditional polystyrene foam, polyurethane foam and polyethylene foam because of its good mechanical properties, excellent heat resistance and environmental protection properties. Application prospects. [0003] General-purpose polypropylene materials are poorly expandable, and their suitable foaming viscosity and temperature ranges are narrow. Therefore, in order to improve the foamability and processing stability of polypropylene materials, polypropylene materials with high melt tensile tension and sui...
