Novel high-temperature-resistant silica gel pad and mold for processing same

Abstract

The invention discloses a novel high-temperature-resistant silica gel pad and a mold for processing the same. The novel high-temperature-resistant silica gel pad comprises the following raw materials in parts by weight: 75 parts of vinyl silicone rubber, 20-40 parts of a heat-resistant additive, 2-5 parts of hydrogen-containing silicone oil and 2-5 parts of a cross-linking agent; and the raw materials specifically comprise 75 parts of vinyl silicone rubber. When the silica gel raw materials are prepared, the heat-resistant additive methyl phenyl silicon-nitrogen rubber is added into the raw materials, so that the high-temperature resistance of the silica gel pad can be effectively improved, and the service life is effectively prolonged when the silica gel pad is used in a high-temperature environment; in the process of preparing the silica gel pad through an upper mold and a lower mold, the raw materials can be sucked through a suction cup, then after processed materials are discharged from a mold, a motor is used for driving an annular pipe to turn over, move to a lower mold forming cavity and then descend, and thus the automatic feeding effect can be achieved, material preparation can be conducted by utilizing the processing time, continuous uninterrupted processing is achieved, and then the efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of silica gel pad processing, in particular to a novel high-temperature-resistant silica gel pad and a mold for processing the same. Background technique [0002] Silica gel, also known as silicic acid gel, is a granular porous silica hydrate. It is an amorphous substance with a transparent or milky white appearance. It is made by adding acid to sodium silicate and then washing and drying. It has stable chemical properties and does not burn. , Silica gel is a highly active adsorption material, mainly used as a desiccant and an adsorbent in column chromatography and thin layer chromatography. Generally speaking, it can be divided into two categories: organic silica gel and inorganic silica gel. [0003] Silicone pad has a certain degree of flexibility, excellent insulation, compressibility, and natural stickiness on the surface. It is specially produced for the design scheme of using gaps to transfer heat; it...

Problems solved by technology

[0004] In the process of processing and producing the existing silica gel pads, the raw materials of the corresponding formula are often mixed and then go through a series of processing to obtain the silica gel raw materials, and then the silica gel raw materials are processed under the processing mold to obtain the formed silica gel pads. However, the high temperature resistance of the existing silicone pads is average, and the existing processing molds often manually add silicone raw materials into the mold cavity during the processing, and there are multiple molding cavities in the mold cavity, so that the raw materials can be processed at home. At the same time, the staff needs to add materials one by one, which is inconvenient to operate and affects the processing efficiency. Moreover, after the silicone pad is formed, it needs to manually cut the edge waste. The manual cutting efficiency is low, and it is easy to cause damage to the hands of the staff. , for this reason, we propose a new type of high temperature resistant silicone pad and its processing mold
