The invention discloses a high-performance water-based automotive interior adhesive and a preparation method thereof, and relates to the technical field of automotive interior adhesives. The high-performance water-based automotive interior adhesive is prepared from the following components in parts by mass: 30 to 50 parts of modified water-based polyurethane emulsion, 15 to 30 parts of acrylic emulsion, 5 to 15 parts of tackifying resin, 2 to 6 parts of coalescing agent, 0.5 to 3 parts of cross-linking agent, 0.1 to 0.5 part of flatting agent, 0.1 to 0.5 part of defoaming agent, 0.2 to 1 part of thickening agent, 0.05 to 0.3 part of preservative and 10 to 25 parts of deionized water. The water-based polyurethane emulsion is subjected to surface modification through the coupling agent with a specific structure, the bottleneck that the interface bonding force between a traditional water-based adhesive and PP and other low-surface-energy and non-polar base materials is insufficient is broken through, and high peel strength can be achieved without flame, corona or prime coat or other pretreatment procedures on the PP base materials; and the bonding process flow of the automotive interior trim parts is greatly simplified.

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.

This invention relates to the field of battery technology, specifically to a battery. The battery includes a positive electrode, a negative electrode, and a separator. The positive electrode includes a positive current collector and a positive active material layer. The positive active material layer includes a three-dimensional network framework and positive active material located within the three-dimensional network framework. The three-dimensional network framework is formed by a conductive binder, which includes carbon nanotubes and an adhesive layer. Along the thickness direction of the positive active material layer, the positive active material layer includes a first surface away from the positive current collector, and the conductive binder is distributed on the surface of the first surface. The separator includes a carrier layer and a coating layer. The coating layer adjacent to the first surface of the positive electrode is a first coating layer. The proportion W of the projected area of ​​the first coating layer on the surface of the carrier layer in the surface area of ​​the carrier layer is 5%-65%. The battery of this invention has high interfacial adhesion between the separator and the positive electrode, which can maintain good adhesion during cycling, improving the cycle performance of the battery.
