Description

Technical Field

[0001] The utility model relates to the field of silicone rubber processing, in particular to a filtering and stirring device for silicone rubber processing. Background Technique

[0002] Silicone rubber refers to a rubber whose main chain is composed of alternating silicon and oxygen atoms, and usually has two organic groups connected to the silicon atom. Ordinary silicone rubber is mainly composed of siloxane linkages 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 cyano can improve the temperature resistance and oil resistance of silicone rubber. Silicone rubber has good low temperature resistance and can generally still work at -55°C. After introducing phenyl, it can reach -73°C. The heat resistance of silicone rubber is also very prominent and can work long-term at 180°C. It can also withstand temperatures slightly higher than 200°C for several weeks or longer and still have elasticity, and can instantaneously withstand high temperatures above 300°C. Silicone rubber has good air permeability, and its oxygen permeability is the highest among synthetic polymers;

[0003] An existing filtering and stirring device for silicone rubber processing (application number: 202120690043.2) includes a base, a first bevel gear, a second bevel gear, a first gear and a second gear.

At the same time, most of the existing filtering and stirring devices for silicone rubber processing do not have the function of automatically circulating and stirring up and down, resulting in insufficient stirring; the above still exists, and the filtering of silicone rubber is not thorough, resulting in the need to filter the silicone rubber raw materials multiple times, resulting in poor filtering efficiency of the silicone rubber raw materials and increasing the work of the staff to put materials into the filtering cylinder multiple times.
