Lianrui New Materials obtained the patent for epoxy resin potting glue for automotive film capacitors to improve the reliability and extend the service life of film capacitors.

News on November 22, 2023, according to the announcement of the State Intellectual Property Office, Jiangsu Lirui New Materials Co., Ltd. has obtained a project called "Epoxy resin potting compound for automotive film capacitors and its preparation method" ", authorization announcement number CN115029093B, application date is June 2022.

The patent abstract shows that the invention discloses an epoxy resin potting glue for automotive film capacitors and a preparation method thereof. The epoxy resin potting glue is composed of a modified epoxy resin and a modified acid anhydride curing agent with a mass ratio of 100:85 to 100, wherein the modified epoxy resin is composed of 100 parts of epoxy resin and 5 to 15 parts of ring. Composed of oxygen diluent, 1 part silane coupling agent, 0.7 parts color paste, 0.3 parts silicone defoaming agent, 170~225 parts inorganic filler, 15~34 parts environmentally friendly halogen-free organic flame retardant, modified acid anhydride curing The agent consists of 100 parts of acid anhydride, 1 to 3 parts of curing accelerator, and 195 to 225 parts of inorganic filler. The cured epoxy resin potting glue of the present invention has high mechanical properties, good heat resistance, good flame retardancy and small thermal expansion coefficient. When used in potting film capacitors, it can improve the reliability of the film capacitor and extend its service life. .
