Abstract

The invention discloses an environment-friendly polyurethane composite plastic runway material. The plastic runway material is prepared from the following components in parts by weight: 42 parts of polyether polyol, 18 parts of isocyanate, 10 parts of modified polypropylene, 7 parts of 9, 10-phenanthrenequinone, 5 parts of 1,4-cyclohexynol, 3 parts of polyvinyl alcohol, 1 part of polycarboxymethyl fiber, 4 parts of silicone powder, 2 parts of stainless steel fiber, 3 parts of ethylene bis stearamide, 0.5 part of catalyzer, 8 parts of filler, 0.2 part of antiager, 0.4 part of flame-retardant and 0.5 part of pigment. The invention also discloses a preparation method of the environment-friendly polyurethane composite plastic runway material. The plastic runway material prepared by the preparation method disclosed by the invention is not only green and environment-friendly, but also has excellent tensile strength, elongation at break, rebound resilience and flame retardance. Besides, a testing result also displays that the prepared plastic runway material of each embodiment has good wear resistance and meets actual application demands.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an environment-friendly polyurethane composite plastic runway material and a preparation method thereof. Background technique [0002] The plastic track began in the 1960s with the plastic horse racing track laid by the 3M company in the United States with polyurethane materials. Compared with cinder and gravel fields, the plastic runway has the advantages of good elasticity, good shock absorption performance, wear resistance and anti-aging, does not pollute the environment, and is easy to clean and maintain. For this reason, the plastic track has been internationally recognized as the best race track. [0003] The polyurethane plastic runway used in the Bird's Nest Stadium of the 2008 Olympic Games in my country has the advantages of good elasticity, shock absorption, skid resistance, wear resistance and easy cleaning and maintenance. Now many primary and secondary s...
