Problems solved by technology
[0003] The filter device of existing silicone rubber elastic material vulcanization gas mainly has the following technical defects: one, the traditional gas filter device adopts activated carbon to contact with gas, but activated carbon is in a static state, and then causes the contact area of activated carbon and gas to be small, The problem of low utilization rate of activated carbon and poor initial filtering effect; Second, the traditional gas filter device uses spraying to filter the gas twice, but the path of the gas flowing through the spraying is a straight path, which leads to harmful substances and spraying The contact angle of the aerosol is too single, resulting in low spray filtration efficiency and wasting a lot of water resources

The invention discloses a silicone rubber elastic material and a preparation method thereof. The silicone rubber elastic material comprises an inlet pipe, a filtering device, a guide pipe and a spraying device. The filtering device comprises a spherical shell, a first motor, a rotating shaft, a rolling shell and a retarding device, the spherical shell is connected to the right side of the inlet pipe, and the first motor is arranged on the right side of the spherical shell; the left side of the first motor is rotationally connected with the rotating shaft, the right end of the rotating shaft is connected with the rolling shell, and the retarding device is installed on the rolling shell. According to the vulcanization filtering device, through the matching effect of the spherical shell, the rolling shell, the fixed shell and the rotating wheel, the purpose of driving activated carbon particles to roll around the inner side wall of the spherical shell is achieved, and thus the contact area between the activated carbon particles and vulcanization gas is increased; therefore, the problems of small contact area between the active carbon and the gas and low utilization rate of the active carbon caused by the static state of the traditional active carbon are solved.
Description
technical field [0001] The invention relates to the technical field of silicone rubber, in particular to a silicone rubber elastic material and a preparation method thereof. Background technique [0002] Silicone rubber needs to be vulcanized during the preparation process to form the silicone rubber. After the reaction between the vulcanized gas and the silicone rubber, it is very important for the waste vulcanized gas to be filtered and discharged. [0003] The filter device of existing silicone rubber elastic material vulcanization gas mainly has the following technical defects: one, the traditional gas filter device adopts activated carbon to contact with gas, but activated carbon is in a static state, and then causes the contact area of activated carbon and gas to be small, The problem of low utilization rate of activated carbon and poor initial filtering effect; Second, the traditional gas filter device uses spraying to filter the gas twice, but the path of the gas f...
