[0024] The present invention will be described in more detail below in conjunction with the examples. It should be understood that the present invention should not be considered as limited to these examples.
[0025] Component A:
[0026] Has at least two alkenyl groups in the molecule and a viscosity of 10-100,000mm at 25°C 2 / s organopolysiloxane;
[0027] Component B:
[0028] Organohydrogenpolysiloxanes represented by the following structures:
[0029]
[0030] Component C:
[0031] Aluminum powder with an average particle size of 2 μm;
[0032] Component D:
[0033] Isopropyl triisostearyl titanate.
[0034]When preparing the heat-conducting polysiloxane composition of the present invention, the components A, B, and D are first stirred and mixed at room temperature according to the blending ratio shown in Table 1, so that a certain crosslinking reaction occurs between component A and component B , and then add component C according to the ratio shown in Table 1 ...
