Abstract

The invention discloses a polypropylene composite used for the injection moulding splicing floor. The polypropylene composite comprises the following components by weight percent: 23-84% of co-polypropylene, 5.0-20% of toughening agent, 5.0-20% of white oil, 5.0-30% of reinforcing agent, 0.5-5.0% of weather resistant colourant and 0.5-2.0% of other additives, wherein the additives at least contain one of light stabilizer, antioxidant and processing aid. The polypropylene composite can satisfy the use requirements of the indoor and outdoor splicing floors and has low temperature resistance, high impact strength and good elastic resilience.

Description

technical field [0001] The invention relates to a modified polypropylene compound, in particular to a polypropylene compound used for injection-molded plastic lattice splicing floors and a preparation method thereof. Background technique [0002] Plastic splicing floor is a new type of flooring building material. Its shape is grid-like square, surrounded by mortise and tenon buckle structure, and it is installed into a piece of field floor through splicing. Plastic splicing flooring originated in the United States in the 1980s. It has been widely used because of its unique design, convenient molding, superior performance, easy installation, and recyclability. At present, there are more than 100,000 splicing sports floors in the world. stadium. At the beginning of this century, plastic mosaic flooring entered China. After years of promotion and use, it gradually entered schools, public places, government agencies, military and other departments. At the same time, it also ent...
