Description

Technical Field

[0001] The utility model relates to the technical field of silicone rubber production equipment, in particular to a production equipment for conductive foamed silicone rubber. Background Technique

[0002] Generally, the blowing agents selected for silicone rubber foaming materials are divided into two categories: organic blowing agents and inorganic blowing agents. Organic blowing agents include azo compounds, sulfonyl hydrazide compounds, nitroso compounds, etc., such as AC (azodicarbonamide), OBSH (4,4-oxybisbenzenesulfonyl hydrazide), etc. The decomposition products of such organic blowing agents contain substances such as amines and benzene rings, which have odors and are not environmentally friendly. Inorganic blowing agents include sodium bicarbonate, ammonium bicarbonate, ammonium chloride, sodium carbonate, etc. Such inorganic blowing agents have less foaming amount and limited applications. In recent years, a thermoplastic expandable foamed microsphere has also emerged on the market as a blowing agent. This is a polymer particle with a typical core-shell structure, with a thermoplastic polymer as the shell layer and a blowing agent (low-boiling alkane or other compounds) as the core. The compatibility of such a blowing agent with silicone rubber is poor, the surface of the prepared product is not smooth, the particle feeling is obvious, and it is not easy to color, and the thermal stability is poor.

[0003] In the prior art, when producing silicone rubber, various raw materials are doped together and added into a mixing tank, and a stirring rod is used to mix them evenly. After mixing, an extrusion device is used to extrude and form them.

One end of the output end of the second servo motor 15 extending into the pressing shell 10 is fixedly connected to the driving gear 18. The outer wall of the driving gear 18 is meshed with the driven gear 19. One end of the driven gear 19 extending to the outer wall of the pressing shell 10 is fixedly connected to the outer wall of the rotating plate 12. The model of the second servo motor 15 is not limited, as long as it meets the actual use requirements;

[0025] In the specific implementation process, it is particularly pointed out that with the cooperation of the second servo motor 15, the driving gear 18 and the driven gear 19, the second servo motor 15 is used to drive the driving gear 18 to rotate, and through the meshing of the driven gear 19 and the driving gear 18, the rotating plate 12 is driven to rotate, and the extrusion head 13 on one side of the rotating plate 12 is replaced, and the silicone rubber is extruded into different shapes, which solves the problem that in the prior art, when in use, the extrusion head 13 is replaced by rotating bolts, resulting in inconvenience for the staff during replacement;
