Description

Technical Field

[0001] The utility model belongs to the technical field of silicone rubber, in particular to a silicone rubber filter. Background Art

[0002] Silicone rubber is mainly composed of siloxane chains containing methyl and a small amount of vinyl. The introduction of phenyl can improve the high and low temperature resistance of silicone rubber, and the introduction of trifluoropropyl and cyanide can improve the heat and oil resistance of silicone rubber. In the production process of silicone rubber, it is usually necessary to use a filtering device to filter the silicone rubber to obtain a relatively pure raw material.

[0003] In the current silicone rubber filter, after filtering, some silicone rubber remains in the filter residue, resulting in a waste of material.

[0004] For example, a Chinese patent document (application announcement number CN212948620U) of the prior art discloses a chair with adjustable armrests. The device prevents the material temperature from being too high to form oversulfurization, prevents the material from splashing out to cause safety accidents and material waste, and can promptly scrape off the material stuck on the inner wall of the hopper, making cleaning easy. The prior art has the following problem: after filtering, some silicone rubber remains in the filter residue, causing material waste.

[0005] Therefore, in view of this situation, it is urgent to design and produce a silicone rubber filter to meet the needs of practical use. Utility Model Content
