Problems solved by technology

[0005] Due to the poor compatibility between the thermally conductive filler and the silicone rubber matrix, the amount added has a great influence on the mechanical properties of the composite material
When the amount of thermally conductive filler added is large, the thermal conductivity is better, but in order to ensure the overall performance of the silicone rubber composite material, only the amount of high temperature resistant filler can be controlled, so it is difficult to ensure the simultaneous realization of the two functions of low temperature heat conduction and high temperature heat insulation , so that the current invention can only be aimed at one of the two functions of heat conduction or fire resistance and heat insulation
For example: the invention patent CN201510354977 provides a high thermal conductivity polyvinyl chloride sheath material for c

Description

technical field [0001] The invention relates to a porcelainizable polymer material and a preparation method thereof, in particular to a normal temperature heat conduction-high temperature heat insulation porcelainizable polymer material and a preparation method thereof. Background technique [0002] Porcelainable polymer material is a new type of thermal protection material that has polymer properties at room temperature and can be transformed into a self-supporting ceramic material at high temperature. In many industrial fields such as energy, chemical industry and metallurgy, the application prospect of porcelainable polymers is broad. For example: in the field of power transmission, the wire core itself has resistance when transmitting electric energy. The greater the current, the more heat the wire core generates, and the temperature rise of the wire core will increase its own resistance, further expanding the power transmission process. The loss due to the temperature ...
