On November 22, 2023 message, according to announcement of bureau of national intellectual property, inc. of new material of Jiangsu couplet luck obtains the name is capacitance of “ car film to seal glue and ” of its preparation method with epoxy resin fill, CN115029093B of accredit announcement date, application date is in June 2022.
Patent summary shows, this invention made public capacitance of film of a kind of car to seal glue and its preparation method with epoxy resin fill. Narrates epoxy resin fill seals glue to be 100:8 by quality comparingThe modified epoxy resin of 100 and agent of solidify of modified acid anhydride comprise 5 ~ , among them modified epoxy resin by 100 epoxy resin, 5 ~ 0.3 0.7 coupling agent of alkyl of a thinner of 15 annulus oxygen, silicon, lubricious oars, organic silicon kind anti-foaming agent, 170 ~ 225 inorganic filling, 15 ~ 34 environmental protection comprise without haloid and organic fire retardant, agent of solidify of modified acid anhydride by 100 acid anhydride, 1 ~ 225 inorganic filling comprise 3 solidify accelerant, 195 ~ . The mechanical function that the epoxy resin fill of this invention seals glue condensate tall, hear resistance good, flame retardation is good, hot coefficient of expansion is small, in applying at fill to seal film capacitor, can raise the dependability of film capacitor and prolong its service life.
