Abstract

This case discloses a transparent waterproof potting material, including the following materials: polyurethane prepolymer; α, ω-dihydroxypolydimethylsiloxane; alkoxysilane; Polymer; Triethylenediamine; Plasticizer; Structural aid; Silane coupling agent. The invention provides a transparent waterproof potting material. Polyurethane and acrylic resin are used to modify organic silicon to obtain a transparent waterproof potting material with strong adhesion, excellent electrical insulation performance, ultraviolet resistance and high corrosion resistance.

Description

technical field [0001] The invention relates to a potting material, in particular to a transparent waterproof potting material. Background technique [0002] Potting material, also known as electronic glue, is a broad term. Used for bonding, sealing, potting and coating protection of electronic components. The potting glue is liquid before it is cured and has fluidity. The viscosity of the glue varies according to the material, performance and production process of the product. Only when the potting glue is completely cured can its use value be realized. After curing, it can play the role of waterproof, moisture-proof, dust-proof, insulation, heat conduction, confidentiality, corrosion resistance, temperature resistance, and shock resistance. With the expansion of the application range, higher requirements are put forward for the comprehensive performance of potting materials. [0003] At present, the most widely used potting materials are various synthetic polymers, amon...
