Abstract

The invention discloses a deep curable and highly transparent condensation-type silicone potting glue which is made by the mixing of component A and component B. The component A mainly contains a, omega-dihydroxy polydimethylsiloxane, and the component B mainly contains methyl silicone oil. A preparation method and application of the deep curable and highly transparent condensation-type silicone potting glue are also disclosed. A formula system of the silicone potting glue has the advantages of having good compatibility, maintaining original high transparency when realizing deep and overall curing, better meeting the needs of deep and transparent potting, and thus facilitating widespread use thereof in the field of transparent potting.

Description

technical field [0001] The invention relates to the technical field of polymer potting materials, in particular to a condensation type silicone potting glue and its preparation method and application. Background technique [0002] At present, most of the transparent potting materials used in the field of potting in the prior art are epoxy resins, but due to their poor weather resistance, aging resistance, and yellowing resistance, and high stress at low temperatures, epoxy resins The deficiencies and defects of resins in transparent potting applications are becoming increasingly prominent. In addition, with the rapid development of production and economy, the application environment is becoming more and more extensive and complex, so the requirements for material performance are also getting higher and higher. Silicone rubber has good advantages due to its good weather resistance, aging resistance, UV resistance, yellowing resistance and other properties. However, the sili...
