and step four, adding the mixed material obtained in the step three into an arc-shaped silica gel gasket mold, and performing injection molding through the mold to obtain the arc-shaped silica gel gasket.
8. The preparation method of the PVC composite material insulation board according to any one of claims 1 to 7, characterized by comprising the following steps:
s1, selecting an I-shaped frame which meets the requirement, and cleaning the first mounting groove and the second mounting groove on the two sides of the I-shaped frame;
s2, bonding the foam cotton layer on the inner side of the first mounting groove, bonding the graphite plate layer on the outer side of the first mounting groove, and uniformly coating adhesive on the inner side of the graphite plate layer to bond the graphite plate layer and the foam cotton layer together;
s3, bonding the PVC plastic plate layer on the inner side of the second mounting groove, then uniformly bonding the arc-shaped silica gel gasket on the surface of the PVC plastic plate layer, bonding the glass cotton layer on the outer side of the second mounting groove, and enabling the inner side of the glass cotton layer to be in contact with the arc-shaped silica gel gasket, thereby obtaining the PVC composite material insulation board.
