Description

Semi-automatic mill for silicon rubber

Technical Field

The utility model relates to a rubber processing technology field specifically is a semi-automatic mill equipment of silicon rubber.

Background

Silicone rubber refers to rubber having a backbone composed of alternating silicon and oxygen atoms, with the silicon atoms typically having two organic groups attached to them. Conventional silicone rubbers consist predominantly of siloxane segments containing methyl groups and small amounts of vinyl groups. The introduction of phenyl can improve the high and low temperature resistance of the silicone rubber, and the introduction of trifluoropropyl and cyano can improve the temperature resistance and oil resistance of the silicone rubber. The silicon rubber has good low-temperature resistance and can still work at the temperature of minus 55 ℃. After the introduction of phenyl, a temperature of-73 ℃ can be reached. The silicon rubber has outstanding heat resistance, can work for a long time at 180 ℃, can still have elasticity for a plurality of weeks or more even at the temperature slightly higher than 200 ℃, and can instantaneously resist the high temperature of more than 300 ℃. Silicone rubber has good gas permeability, and oxygen transmission rate is the highest among synthetic polymers. In addition, the silicon rubber also has the outstanding characteristics of physiological inertia and no coagulation, so the silicon rubber is widely applied in the medical field.

In the existing technology for producing silicon rubber compound, the mixed rubber material is overturned on a bedplate from a kneader by turning over a cylinder. Then cutting the mixture into small pieces by using a steel wire or a cutter, cooling the small pieces, putting the small pieces on an open rubber mixing mill in batches, and further mixing the small pieces by using shearing force generated by the asynchronous rotating speed of two rollers. Finally, cutting off the milled rubber material by a blade and conveying the rubber material to a filtering station. The open mixing station is the most bitter station in the whole production of the silicon rubber compound, and has high requirements on physical strength of operators. In the actual operation process, the sizing material piled on the roller needs to be cut and turned by an operator continuously. When the open mill runs, the potential safety hazard is very large, and the roller is easy to roll the arm into the open mill, so that personal injury is caused; in addition, rubber of the existing equipment needs to be processed repeatedly, and the surface of the silicon rubber is easy to adhere after being heated, so that the extruder is inconvenient to discharge.
