Abstract

The invention discloses a glass microsphere filled polypropylene composition and a preparation method thereof. The glass microsphere filled polypropylene composition is prepared from, by weight, 100 parts of polypropylene, 3 to 5 parts of polypropylene grafted maleic anhydride, 1 to 2 parts of polyethylene wax, 10 to 35 parts of glass microspheres, 1 to 3 parts of sodium dodecyl benzene sulfonate, 0.05 to 0.1 part of antioxidant 1010 and 0.05 to 0.1 part of antioxidant 168. The sodium dodecyl benzene sulfonate is added into the polypropylene, so that the interface bonding capacity between the polypropylene and the glass beads is greatly enhanced, and the mechanical property of the polypropylene composition can be greatly improved; and a prepared polypropylene composition injection molded part has the characteristics of low density, light weight, excellent mechanical property and the like.

Description

technical field [0001] The invention belongs to the field of polymer composite materials, in particular to a polypropylene composition filled with glass microspheres and a preparation method thereof. Background technique [0002] Polypropylene, referred to as PP, is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene (PP) is a thermoplastic synthetic resin with excellent performance, which is a colorless and translucent thermoplastic lightweight general-purpose plastic. With chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties, etc., polypropylene has been rapidly used in machinery, automobiles, electronic appliances, construction, textiles, and packaging since its inception. It has been widely developed and applied in many fields such as agriculture, forestry, fishery and food industry. In recent years, with the rapid development of my country's packagin...
