Problems solved by technology

When athletes run on the plastic track, the floating particles on the surface are easy to splash due to the force of the athlete's feet, which affects the normal performance of the athlete; it also affects the sanitation, appearance and normal use of the sports venue; at the same time, Since the production of rubber granules requires energy-intensive processes such as rubber mixing, vulcanization, and crushing, when rubber granules are used as the surface layer, the production process consumes a lot of energy

Abstract

The invention discloses a non-solvent-type sports field skid-resistant layer texture self-formation material and relates to the field of plastic materials. The non-solvent-type sports field skid-resistant layer texture self-formation material comprises, by weight, a component A comprising 80 to 120 parts of polyether polyol (having molecular weight of 2000) and 30 to 40 parts of MDI (diphenylmethane diisocyanate), and a component B comprising 25 to 35 parts of polyether polyol (having molecular weight of 4900), 30 to 40 parts of polyether polyol (having molecular weight of 3000), 30 to 45 parts of a filler, 3 to 6 parts of a polyamide thickener, 0.5 to 1 part of an antioxidant, 0.5 to 1 part of an ultraviolet absorber, 0.1 to 0.5 parts of a catalyst, 10 to 15 portions of a vegetable oil plasticizer and 5 to 8 portions of a pigment. The non-solvent-type sports field skid-resistant layer texture self-formation material has the advantages that particles of the surface layer do not easily fall off, skid resistance, elasticity and shock absorption performances are good, comfort is improved, a fatigue degree is reduced, wear, oil and aging resistance is very strong, a service life is long, and the material is beautiful and environmentally friendly.

Description

technical field [0001] The invention relates to plastic materials, in particular to a solvent-free anti-skid layer self-knotting material for sports grounds. Background technique [0002] The existing plastic runway products in the domestic market are mainly PU plastic runways, and its surface layer (anti-skid layer) mainly uses EPDM rubber particles. Due to the poor bonding between EPDM rubber and polyurethane materials, this kind of plastic runway There will usually be free rubber particles on the surface of the finished product. When athletes run on the plastic track, the floating particles on the surface are easily splashed due to the force of the athlete's feet, which affects the normal performance of the athlete; it also affects the sanitation, appearance and normal use of the sports venue; at the same time, Since the production of rubber granules needs to go through energy-intensive processes such as rubber mixing, vulcanization and crushing, when rubber granules are...
