[0027] S2, preparation of coating material
[0028] Specifically, the coating material is obtained by mixing the first mixture with 2-5 parts of natural rubber, 0.2-0.9 parts of insoluble sulfur, 0.2-1 part of vulcanization accelerator, 1-5 parts of antioxidant, and 3-8 parts of active agent. In the second mixing process, ultrasonic mixing may not be used to ensure the mixing uniformity of each component.
[0029] Specifically, in the preparation process of the coating material, the first mixture is mixed with natural rubber, vulcanization accelerator, antioxidant and active agent in a high mixer for 15-35 minutes to obtain the second mixture; then, the second mixture is added to the double Blended and extruded in a screw extruder. The extruder can be a general twin-screw extruder, and the uniformly mixed materials can be made into finished products, which can be used for laser spraying and the like.
[0030] Preferably, the mixing temperature is controlled at 50-60°C in the...
