Abstract
The invention relates to a preparation technology of a silica gel plate. At first, a corresponding cover die is engraved according to a three-dimensional diagram for design and processing of the die assembly. The cover die comprises a cavity die and an upper die. The upper die is cleaned with mixed liquid of vinyl triethoxy silane, absolute ethyl alcohol, de-ionized water and hydrochloric acid. The silicone oil parting compound is coated on the surface of the cavity die and heated until the cavity die is completely moistened by the parting compound. After R401/70S or mixture of R401/70S and R401/40S is mixed and then sulphurated and the dies are matched and cut, the post cure is performed. The finished product is baked in an air-blast oven. As the solid cover die and the processing technology thereof are adopted, the preparation technology of the invention can be used in the hot stamping surface with different radian measures or the irregular hot stamping surface and has the advantages that the hot stamping graphic context is full, clear, and high in surface smoothness. The gold stamping with good effect adopts the solid silica gel module as the production technology.
