Abstract

The invention provides a micro-foaming rubber runway. The micro-foaming rubber runway comprises micro-foaming rubber particles and a polyurethane adhesive, the polyurethane adhesive is used for adhering and curing the micro-foaming rubber particles to form the micro-foaming rubber runway, the micro-foaming rubber runway layers are stacked and are adhered and cured through a polyurethane adhesive to form the micro-foaming rubber runway layers, the micro-foaming rubber particles are prepared from the following raw materials in parts by weight: 100 parts of ethylene propylene diene monomer, 20-30parts of a reinforcing agent, 3-7 parts of a vulcanizing agent, 3-5 parts of a coupling agent, 5-10 parts of a foaming agent and 1-5 parts of an anti-aging agent, and the foaming agent comprises thefollowing components in parts by weight: 4-8 parts of an AC foaming agent and 1-2 parts of 2, 5-ditert-pentylhydroquinone. The invention provides the micro-foaming rubber runway with good elasticity,good tensile and tear resistance and excellent anti-aging performance and a preparation method of the micro-foaming rubber runway.

Description

technical field [0001] The invention relates to the technical field of plastic runway filling particles, in particular to a microfoamed rubber runway and a preparation method thereof. Background technique [0002] According to the structure and materials of the plastic runway, it can be divided into: all-plastic plastic runway, hybrid plastic runway, and breathable plastic runway. Because of the low cost, good water permeability and elasticity of breathable plastic track, which meets the daily teaching and training requirements of universities, middle schools and primary schools, its pavement ratio accounts for 63% of the plastic track. The breathable plastic runway is laid by mixing EPDM rubber particles and polyurethane adhesive. [0003] Now many plastic runway particles on the market are mostly made of EPDM rubber, but the runway formed by the current EPDM rubber has insufficient elasticity, tensile tearing performance, and poor aging resistance. It needs to be replace...
