Description

TECHNICAL FIELD

[0002] Silicone rubber refers to the rubber whose main chain is alternately composed of silicon and oxygen atoms, and the silicon atom is usually connected with two organic groups. Ordinary silicone rubber is mainly composed of silicon-oxygen chain segments containing methyl and a small amount of vinyl groups.

[0003] Silicone rubber also has outstanding heat resistance. It can work for a long time at 180 DEG C, and can also withstand a few weeks or longer at slightly higher than 200 DEG C while still having elasticity. It can also withstand high temperatures above 300 DEG C for a short time. Silicone rubber has good air permeability, and its oxygen transmission rate is the highest among synthetic polymers. In addition, silicone rubber also has the outstanding characteristics of physiological inertia and does not cause blood clotting, so it is widely used in the medical field.

[0004] Silicone rubber needs to be mixed thoroughly during raw material preparation. The existing manual stirring method is inefficient and not uniform. Therefore, a raw material mixing structure for silicone rubber preparation is proposed. SUMMARY
