Problems solved by technology

[0003] However, the heat exported to the outside of the battery assembly unit is likely to cause heat and fire in other components other than the battery assembly unit, which in turn will cause the entire new energy battery to ignite and explode.
In addition, the heat-conducting silica gel currently used to separate each battery module unit has low flame retardancy, and the fire prevention effect is not ideal. It is easy to cause a large-scale fire or even battery explosion, endangering life safety.

Abstract

The invention relates to the technical field of packaging materials, in particular to a silica gel packaging part for a new energy battery and a preparation method of the silica gel packaging part. The silica gel packaging part comprises a silicone rubber layer and a glass fiber cloth layer covering the outer surface of the silicone rubber layer, wherein the silicone rubber layer comprises raw materials in parts by weight as follows: 100 parts of composite silicone rubber, 25-35 parts of a reinforcing agent, 2-6 parts of hydroxyl-terminated polydimethylsiloxane, 5-15 parts of dimethicone, 75-85 parts of a compound synergist, 0.1-0.5 parts of an amino coupling agent, 0.1-0.5 parts of zinc stearate and 1-5 parts of a vulcanizing agent. With the adoption of the silicone rubber and glass fibers, insulativity, heat resistance, heat insulation property, flame retardance and corrosion resistance of the packaging part can be improved, when meeting flame combustion, the silica gel packaging part can absorb a large amount of heat and can also stop flame from passing, insulate air and reduce the fire spreading or affecting range, and protection for the battery is improved.

Description

technical field [0001] The invention relates to the technical field of packaging materials, in particular to a silica gel package for new energy batteries and a preparation method thereof. Background technique [0002] With the popularization of new energy sources, more and more products (such as new energy vehicles, etc.) They are all spaced or covered with heat-conducting silica gel to dissipate the heat generated by the battery assembly unit to prevent the battery assembly unit from catching fire. [0003] However, the heat exported to the outside of the battery assembly unit is likely to cause heat and fire in other components other than the battery assembly unit, and then cause the entire new energy battery to ignite and explode. In addition, the heat-conducting silica gel currently used to separate each battery module unit has low flame resistance, and the fire prevention effect is not ideal. It is easy to cause a large-scale fire or even battery explosion, endangerin...
