Selection and optimization of process conditions.

It is well known that the thermal conductivity of composite materials can be influenced by the processing technology of conductive filler and material production. Therefore, the processing technology of material production is also the object that we need to focus on. The temperature and pressure used by silicone rubber in the process of curing are likely to affect the thermal conductivity of the composites, such as the mixing of the packing particles and the matrix.

Due to silicone rubber matrix viscosity will increase with the increase of thermal conductive filler and, further room temperature vulcanized silicone rubber to reduce liquidity, it also makes the silicone rubber matrix, the thermal conductive filler addition amount is limited by different degrees. However, due to the different production process (high temperature vulcanization silicone rubber filler added, is completed by the production process of machine, packing tended to be joined by room temperature vulcanization thermal conductive silicone rubber, and cause the thermal conductivity of high temperature vulcanization silicone rubber is room temperature vulcanization thermal conductive silicone rubber is on the high side. The research indicates that the maximum contact or piling of the packing particles can help to improve the thermal conductivity of the matrix materials. In practical production practice, people often mix and fill particles with different kinds and sizes to achieve maximum contact or piling up of filler particles.

Adding in the mixed silicone rubber, methyl silicone oil as a mixed fertilizer, the results make silicone rubber molding processability samples obtained better than not to add fertilizer and using the method of preparation of thermal conductivity of silicone rubber is greatly increased.
