Abstract

The invention provides a polypropylene composite material for an indoor sport floor and a preparation method thereof. The raw material formula of the polypropylene composite material for the indoor sport floor comprises the following components in parts by weight: 30-50 parts of polypropylene, 30-50 parts of polypropylene reclaimed material, 15-40 parts of calcium carbonate, 0.1-0.5 part of antioxidant 1010, 0.1-0.5 part of antioxidant 168, 0.03-0.08 part of diffusion powder EBS (ethylene bis stearamide), 0-0.02 part of sunproof bright-red powder, 0-0.3 part of ultramarine blue powder, 0-0.04part of permanent yellow GR and 5-10 parts of eight bromo ether. The polypropylene composite material provided by the invention has the characteristics of high performance, scratch resistance, good fire resistance and the like and can meet six basic indexes in the sport industry, sport performance is perfect, rebound property meets sport requirement, requirement of sports on light is met, and buffer action during sports is good; meanwhile, the composite material is fireproof and anti-aging, is easy to lay and can be regenerated, service life is long, and colour is beautiful.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to the field of polymer materials for indoor sports floors, in particular to a polypropylene composite material for indoor sports floors and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a general-purpose plastic, which is polymerized from propylene monomers. The material has poor heat resistance, a melting point of 165-175°C, low rigidity, low impact toughness, relatively low hardness, poor low temperature resistance, and Poor scratch performance and easy to burn. In the field of modified plastics, it is difficult to improve its rigidity, toughness, scratch resistance, low temperature resistance and flame retardancy at the same time, and cannot be directly used as raw materials for indoor sports floors. [0003] Indoor sports floors have relatively high requirements on materials. The floor materials need to have good rigidity, toughness...
