Example Embodiment

[0023] Another embodiment of the present invention

[0024] A low-hardness, high-flexibility, two-component condensed silicone potting composition, wherein the production process of the base rubber: add the structure control agent hexamethyldisilazane to the 107 glue, mix it evenly and add it to the The white carbon black treated with hexamethyldisilazane is kneaded for 1 to 2 hours, dehydrated and mixed in vacuum and cooled to obtain a base gum;

[0025] Component A: 100 parts of 1500cs 107 glue (Japan Shin-Etsu), 50 parts of 100cs simethicone (Japan Shin-Etsu), 50 parts of stearic acid treated calcium carbonate (American specialty minerals) with a particle size of less than 2μ, Raven M carbon black (Columbia Company, USA), 20 parts of base rubber;

[0026] Component B: 10 parts of dimethyldiethoxysilane, 5 parts of vinyl triethoxysilane, 2 parts of γ-aminopropyltriethoxysilane, 0.1 part of dibutyltin dilaurate;

[0027]The prepared silicone material was injected into a 2mm deep ...

Abstract

The invention mainly relates to potting adhesive, in particular to a low-hardness and high-flexibility double-component condensed type organic silicon potting adhesive composition suitable for potting a light emitting diode (LED) display screen module. The composition comprises a component A and a component B, wherein the component A comprises a basic polymer, a filling material, a plasticizing agent and a deep curing agent; and the component B comprises a cross-linking agent, a tackifier and a catalyst. The component A and the component B are mixed according to designed proportion to have a cross-linking reaction so as to realize the effects of potting the LED display screen module, preventing adhesive layer cracking during repeatedly bending and folding LED tubes and providing excellent waterproof and dampproof properties.

Description

technical field [0001] The invention mainly relates to a potting glue, in particular to a two-component condensation type silicone potting glue composition which is used for potting LED display screen modules and has low hardness and high flexibility. Background technique [0002] As a modern electronic media, LED electronic display is irreplaceable by any other media due to its flexible display area (dividable, arbitrary assembly), high brightness, long life, large capacity, digitization, and real-time characteristics. of. Due to the relatively complex working environment of the outdoor screen, in order to ensure its long-term stable operation, common protective measures include: waterproof, anti-static, lightning protection, windproof, moisture-proof, antifreeze, etc.; [0003] Room temperature vulcanized silicone rubber is a new type of silicone elastomer that came out in the 1960s. The most notable feature of this rubber is that it can be cured on the spot without heati...
