Abstract

The invention relates to the technical field of polyurethane, and concretely relates to a high-wear-resistance and high-strength polyurethane court material, and a preparation method and a using method thereof. The high-wear-resistance and high-strength polyurethane court material comprises a component A and a component B, a mass ratio of the component A to the component B is (28-82):100, and thecomponent A is a liquid formed by mixing polyether polyol with a crosslinking chain extender according to a mass ratio of (2-4):1; the component B comprises polyether polyol, isocyanate, a filler, a defoaming agent, modified carbon nanotubes, a pigment, a dispersant and a catalyst; and the polyether polyol is polyether polyol with a number-average molecular weight of 3000-6000 and a functionalityof 2-3. The high-wear-resistance and high-strength polyurethane court material get rids of a finish paint, so the delaminating phenomenon of an elastic layer and a finish paint layer is thoroughly avoided, the finish paint material is saved, a large amount of the construction cost is saved, and the construction period is shortened. The invention also provides the preparation method and the using method of the high-wear-resistance and high-strength polyurethane court material.

Description

technical field [0001] The invention relates to the technical field of polyurethane, in particular to a high wear-resistant and high-strength polyurethane court material and a preparation method and application method thereof. Background technique [0002] Polyurethane courts are widely used in indoor environmental protection ground laying and outdoor hard court laying, especially outdoor basketball courts and badminton courts in schools, parks, communities, etc., due to their excellent elasticity, moderate hardness and ball resilience and other physical properties. It is also used in factories, parking lots and other fields. [0003] At present, during the construction of polyurethane paving materials, water-based topcoats or oil-based topcoats are generally applied directly on the surface of the elastomer, which has high requirements for the adhesion of the water-based topcoats or oil-based topcoats. However, the topcoat is prone to delamination caused by poor adhesion, w...
