Breathable polyurethane runway and material mixing device thereof

Abstract

The material mixing device comprises a base layer, a bottom sealing layer, a reinforcing layer, an elastic particle layer and a surface spraying layer, through holes are formed in the reinforcing layer in an up-down penetrating mode at equal intervals, leakage grooves are formed in the positions, corresponding to the through holes, of the upper surface of the bottom sealing layer, and supporting pipes are installed in the leakage grooves in an inserted mode. According to the polyurethane runway, the overall strength of the polyurethane runway is improved through the arranged reinforcing layer, meanwhile, the through holes formed in the reinforcing layer facilitate extension of the supporting pipes, water seepage and ventilation of the base layer and the bottom sealing layer are facilitated through the through holes, residual water can be rapidly discharged, and the reinforcing pipes can be limited through the mounting grooves formed in the bottom sealing layer; meanwhile, the liquid leakage openings formed in the surfaces of the reinforcing pipes in a penetrating mode can rapidly filter out water in the bottom sealing layer, the bubbling phenomenon caused by the fact that water vapor cannot be rapidly diffused is reduced, the phenomena that the surface of the polyurethane runway is uneven and prone to being damaged can be effectively improved, and the reinforcing pipes can further prolong the overall service life of the bottom sealing layer.

Description

technical field [0001] The invention belongs to the technical field of polyurethane processing, and in particular relates to a breathable polyurethane track and a material mixing device thereof. Background technique [0002] Polyurethane track, also known as elastic floor, sports floor, track and field floor, track and field track, etc. Polyurethane is a polymer compound, and polyurethane paving materials are widely used in the construction of sports venues, plastic runways in public sports venues, indoor basketball courts, and volleyball courts. With the continuous improvement of the quality of my country's polyurethane industrial products, the quality of polyurethane paving materials has been greatly improved, and enterprises are constantly on the road to environmentally friendly paving products. However, due to the poor air permeability of the existing polyurethane runway, the accumulation of water between the runway surface layer and the runway base layer increases when...

AI Technical Summary

Problems solved by technology

However, due to the poor air permeability of the existing polyurethane runway, the accumulated water between the runway surface layer and the runway base layer increases when it rains, and the bottom layer of the runway and the runway surface layer cannot discharge the water in time, and the water vapor cannot diffuse quickly. , resulting in bubbling, which will cause the surface of the plastic runway to be uneven and easy to break, so we propose a breathable polyurethane runway and its material mixing device
