The invention relates to the technical field of lithium ion batteries, and provides a high-heat-resistance and high-adhesion lithium battery diaphragm as well as a preparation method and application thereof. The high-heat-resistance and high-adhesion lithium battery diaphragm comprises a base membrane and a coating arranged on at least one surface of the base membrane, and the coating is prepared from polyvinylidene fluoride-hexafluoropropylene copolymer, inorganic particles, a silane coupling agent, acrylate light-cured resin, a photoinitiator and an organic solvent. According to the technical scheme, the problem that the lithium battery diaphragm in the prior art cannot have high heat resistance and high interface adhesion at the same time is solved.

The present application relates to the technical field of high polymer material silicone rubber, and particularly relates to a kind of flame-retardant antistatic high-temperature resistant vulcanized pipe and a preparation method thereof.The present application effectively solves the poor compatibility and performance conflict problem often occurred when realizing high flame-retardant and antistatic function of traditional silicone rubber pipe material by constructing a unique "microscopic island structure".In the preparation process, vinyl MQ silicone resin as a key "interface bridging" component can be preferentially adsorbed on the interface of different polar rubbers and wrapped modified flame retardant to form a "core-shell" micro area, which not only prevents the interference of high-filled flame retardant on the conductive network, but also significantly enhances the interfacial adhesion between methyl silicone rubber and phenyl silicone rubber two phases;At the same time, the assistant crosslinking agent triallyl isocyanurate participates in grafting reaction during vulcanization process, and establishes a stable chemical bond bridge between different rubber phases, which fundamentally avoids the delamination phenomenon of the blending system.
