Problems solved by technology

[0004] During the preparation of the above-mentioned elastomeric material, since the material extruded by the extruder has not yet been finalized, it is prone to disconnection during the stretching process, which in turn leads to a high waste residue rate of the material and increases the production cost of the elastomeric material

preparation example Construction

[0051] A kind of preparation method of the elastomeric material that is used for plastic runway, see figure 1 , including the following steps:

[0052] ① Weighing: Weigh the components of the elastomer material in turn according to the formula, the specific formula is 25kg EPDM, 5kg TPU, 35kg shell powder, 15kg naphthenic oil 4006, 5kg foaming agent, 0.5kg colorant, 0.1kg Antioxidant 1076, 0.2kg antiaging agent AW, 0.1kg odorless DCP and 0.1kg magnesium oxide.

[0053] ②. Stirring: put each component in step ① into a mixer, and stir evenly at 300-320r / min to obtain a mixture.

[0054] ③. Pelletizing: Put the mixture in step ② into the twin-screw extruder, control the working temperature of the twin-screw extruder to 200-220°C, and the screw speed to 40r / min, and extrude to granulate.

[0055] Wherein, the twin-screw extruder 1 that the present invention uses sees figure 2 , the machine head 11 is immersed in the cooling water flowing in the water tank 6, and the discharge ...

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 ...
