Abstract
The invention discloses a preparation method of an elastomer material for a plastic runway and relates to the technical field of high polymer materials. The preparation method comprises the followingoperation steps that (1) all components of the elastomer material are sequentially weighed according to a formula; (2) all the components in the step (1) are stirred to obtain a mixture; (3) the mixture in the step (2) is placed in a double-screw extruder, and materials are extruded in cooling water as particle cutting is conducted; and (4) particles in the cooling water are collected, dried and screened, and thus the elastomer material is obtained. Particle cutting can be conducted while the double-screw extruder extrudes the materials, the production efficiency of the elastomer material is improved, and the preparation method has the advantages of easy and convenient operation and low waste residue rate.
Description
technical field [0001] The invention relates to the technical field of polymer materials, in particular to a preparation method of an elastomer material used for a plastic runway. Background technique [0002] Plastic track, also known as all-weather track and field sports track, has good flatness and physical properties, which is conducive to the effective use of athletes' speed and technology, and reduces the rate of falls, which makes the popularity of plastic track higher and higher. [0003] The existing elastomer material used for plastic track is prepared by placing the raw material in a twin-screw extruder, and the extruded material falls into a water tank in a strip shape to cool and form, and then the cooled and formed strip material is drawn Extend to the cutting machine for cutting, then put the cut material fragments in the pulverizer to cut into small particles, and finally sieve according to the particle size of the particles. [0004] During the preparation ...
