Abstract

The invention belongs to the field of plastic materials, and discloses a composite plastic material for a runway and a preparation method of the composite plastic material. The composite plastic material is composed of polypropylene, poly(decamethylene-decanedioic acid), poly(4-methyl-1-amylene), PTMEG, phenyltrissilane, bisphenol A diglycidyl ether, polyethylene wax, barium sulfate, zirconia and antioxidant BHT. The preparation method includes the steps of grinding, high-speed mixing, double-screw extruding, granulating, drying and product obtaining. The composite plastic material for the prepared runway has the advantages of being high in rebound rate, tensile strength and elongation at break, and the performance of the plastic runway is effectively improved.

Description

technical field [0001] The invention belongs to the field of plastic materials, and relates to a plastic material and a preparation method thereof, in particular to a composite plastic material for a runway and a preparation method thereof. Background technique [0002] The plastic runway needs to have the following characteristics: 1. All-weather use: It can maintain a high level of quality in any season and temperature difference, and can be used immediately after rain, increasing the utilization time and improving the utilization rate of the site. 2. Elasticity: It has moderate elasticity and rebound force, which can reduce physical consumption and improve competition performance. 3. Impact absorption: Appropriately absorb the impact of feet, reduce sports injuries, and are suitable for long-term practice and competition. [0003] The most prominent property of polypropylene is its versatility, which is suitable for many processing methods and uses. Its value and versa...
