Preparation method of silicone electronic potting glue:
◆Two-component condensation type silicone electronic potting compound, generally in a vacuum kneader, a certain proportion of 107 silicone rubber, alumina, magnesium hydroxide and other functional fillers are mixed at a certain temperature for a period of time, and then added The amount of the vinyl silicone oil is adjusted to a viscosity, and the mixture is stirred for a certain period of time by a high-speed shear disperser to prepare an A component, and the remaining crosslinking agent, catalyst and the like are stirred uniformly in a certain amount to prepare a B component.
◆Two-component addition molding silicone electronic potting glue, in a vacuum kneader, a certain amount of vinyl silicone oil, platinum catalyst, functional filler is thoroughly mixed to make A component, vinyl silicone oil, hydrogen silicone oil The functional filler, the inhibitor and the tackifier are uniformly mixed in a vacuum kneader to form a B component.
At present, in the field of electronic potting, silicone electronic potting has a large market share. International giants such as Dow Corning, Wacker, Momentive, Shin-Etsu and China Bluestar (Aiken Group) own this type of products. Some small domestic manufacturers also have production, but the market share is small, especially in the higher-end electronic products, mainly based on the products of foreign manufacturers.
It is hoped that domestic manufacturers will continue to make progress in technology and catch up, continue to expand the market share of domestic products in the silicone electronic potting and sealing rubber market, and enhance the competitiveness and influence of domestic products.
