Example Embodiment

[0015] Example 1

[0016] The production method of the rubber-plastic track of the present invention includes the following steps:

[0017] 1) Glue mixing: Put rubber powder and glue into a mixer, heat to 50°C, and mix into a uniform rubber material; both the base rubber and surface rubber of the track are made of EPDM rubber as raw materials;

[0018] 2) Feeding; send the base layer rubber to the head end platform of the racetrack forming machine, after starting the forming machine, the rubber is evenly scraped into by the scraper;

[0019] 3) Thermal compression molding of the base layer: the heating drum of the molding machine controls the temperature at 135-140℃, and the cured track base layer is conveyed to the end of the molding machine by the conveyor belt;

[0020] 4) Hot press forming of the surface layer: same as the head end, after the surface layer rubber material reaches the tail end platform, the rubber material is smoothed and evenly entered by the scraper. The heating dr...

Abstract

The invention provides a production method of a rubber and plastic runway. The production method comprises the following steps of (1) mixing rubber: putting rubber powder and glue in a mixer, heating to 50 DEG C, and mixing into uniform sizing materials, wherein the sizing materials of a base layer and a surface layer of the runway are made of EPDM (Ethylene-Propylene-Diene Monomer) rubber as raw materials; (2) feeding: sending the sizing material of the base layer to a head platform of a runway forming machine, and turning on the forming machine, so that the sizing material is scraped by a scraper so as to uniformly enter; (3) hot-press forming the base layer: transmitting the solidified base layer of the runway to the tail end of the forming machine by a conveying belt, wherein the control temperature of a heating drum of the forming machine is 135 to 140 DEG C; and (4) hot-press forming the surface layer: like the head end, feeding the sizing material of the surface layer to a tail platform, so that the sizing material is scraped by the scraper so as to uniformly enter, wherein the control temperature of the heating drum is 135 to 140 DEG C, and carrying out solidifying forming on the surface layer of the runway. The production method of the rubber and plastic runway has the following technical effect that the produced rubber and plastic runway has good air permeability and water permeability.

Description

technical field [0001] The invention relates to a production method of a rubber and plastic track, belonging to the technical field of numerical control machine tools. 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 recognized as the best all-weather outdoor sports floor material. [0003] Th...
