Abstract

The invention proposes an environment-friendly and energy-saving material for the surface layer of sports venues, which belongs to the technical field of composite materials, and is prepared from the following raw materials in parts by weight: 30-50 parts of polyether diol, 10-20 parts of polyether triol, 3-10 parts of toluene diisocyanate, 2-5 parts of diphenylmethane diisocyanate, 4-8 parts of modifier, 3-7 parts of silicon-aluminum porous microspheres, 0.2-1 part of anti-settling agent, 0.5-1 part of zinc oxide 15-25 parts of mineral oil, 22-35 parts of white carbon black. The main material of the present invention is a polyurethane material. By adding the above-mentioned modified materials and additives, the prepared material has good properties such as flame retardancy, heat preservation, sound absorption and noise reduction, weather resistance and wear resistance, and anti-skid performance. The service life of the material has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an environment-friendly and energy-saving material for the surface layer of sports venues, a preparation method and application thereof. Background technique [0002] The paving materials generally used for the runways of compound sports venues are multi-layer structures, but they are generally divided into two layers: the bottom layer and the surface layer. The main function of the bottom layer is breathable support, cushioning and elasticity. - 3mm thick polyurethane mortar, and sprinkle EPDM (EthylenePropyleneDieneMonomer, EPDM) particles as the wear surface layer. Because the buffer elastic layer of the bottom layer has poor weather resistance and wear resistance, and its adhesion with EPDM particles is not good, so it is necessary for the surface layer polyurethane glue layer to have the same properties as the buffer elastic layer and EPDM particles of the bottom...
