Abstract

The invention discloses a manufacturing process of water-permeable plastic road surface layer particles, and belongs to the technical field of rubber product processing. The manufacturing process comprises the following steps that raw materials are added into an extruder, the raw materials are heated to a molten state by the extruder and then the extruder extrudes molten materials into a forming cavity with a preset shape of an extrusion body from a machine head body, demolding is performed after cooling forming to obtain particles in the preset shape; and the preset shape is a hexahedron or an octahedron or a sphere with bulges on the surface. In order to solve the problem that only columnar particles in a simple shape and crushed particles in an uncertain shape can be obtained through anexisting process, the manufacturing process can be used for manufacturing particle products in specific shapes, the particle products in the specific shapes are suitable for a water-permeable plasticroad surface layer, the physical properties of tensile strength, impact absorption rate and anti-skid value of the water-permeable road surface plastic road surface can be remarkably improved, the anti-skid value of the water-permeable road surface is remarkably improved, the buffering and anti-skid performance of the road surface are improved, and the water-permeable plastic road surface is particularly suitable for pedestrian greenway bicycle lanes.

Description

technical field [0001] The invention relates to the technical field of rubber product processing, more specifically, it relates to a manufacturing process for processing predetermined-shaped water-permeable plastic road surface particles. Background technique [0002] The plastic track is also called the all-weather track and field track. It is composed of polyurethane prepolymer, mixed polyether, waste tire rubber, EPDM rubber particles or PU particles, pigments, additives, and fillers. The plastic runway has the characteristics of good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. It is conducive to athletes' speed and technical performance, effectively improving sports performance and reducing the rate of falls. The plastic runway is composed of polyurethane rubber and other materials. It has certain elasticity and color, and has certain anti-ultraviolet ability and aging resistance. It is internationally recogni...
