Description

Technical Field

[0001] The utility model relates to the technical field of rubber preparation, in particular to a device for preparing high-temperature resistant heat-vulcanized silicone rubber. Background Art

[0002] High-temperature heat-vulcanized silicone rubber refers to the process of converting polysiloxane into an elastomer through high-temperature vulcanization. It primarily uses high-molecular-weight polymethylvinylsiloxane as the base rubber, mixed with reinforcing fillers and vulcanizing agents, and then vulcanizes under heat and pressure to form the elastomer. The production process of high-temperature heat-vulcanized silicone rubber requires the use of high-temperature heat-vulcanized silicone rubber preparation equipment.

[0003] For example, a high-temperature resistant heat-vulcanized silicone rubber preparation device with Chinese patent application number CN202322866525.0 is provided. By arranging multiple feeding tanks on the tank body, the setting of multiple feeding tanks can pre-add the additives and powders needed later into the feeding tanks, and directly add them to the tank body through the control of the solenoid valve during the subsequent mixing and kneading process, thereby achieving rapid mixing and reaction and accelerating production efficiency; the setting of the annular sealing ring separates the tank body into a lower tank body and an upper tank body. During the mixing reaction at the bottom of the tank body, the material ratio can be pre-carried out in the upper tank body, thereby cooperating with the stirring paddle to achieve rapid feeding and improve production efficiency.
