Abstract

The invention relates to the technical field of foam material preparation, and discloses a foam material applied to a new energy automobile battery pack. The foam material comprises the following rawmaterials in parts by weight: 25 parts of 107 silicone rubber, 8 parts of vinyl silicone oil, 28 parts of heat conduction powder, 5 parts of fumed silica, 20 parts of a flame retardant, 13 parts of melamine phosphate, 4 parts of antimonous oxide, 3 parts of aluminum hydroxide, 0.5 part of an anti-aging agent, 1 part of an inhibitor, 12 parts of hydrogen-containing silicone oil and 0.5 part of a platinum catalyst. The preparation process of the foam material comprises the following steps: step 1, uniformly mixing the materials at room temperature; step 2, adding hydrogen-containing silicone oiland a platinum catalyst, uniformly mixing, and vacuumizing to remove air in the material; and step 3, placing the mixed materials in a foaming device to be foamed for 10 min so as to prepare the foammaterial. The technical problem that the existing foam material is poor in heat conduction function is solved.

Description

technical field [0001] The invention relates to the technical field of foam material preparation, in particular to a foam material used in new energy vehicle battery packs. Background technique [0002] Foam materials can play a sealing and protective role in battery packs, so they are more and more used in new energy vehicle battery packs. The new energy vehicle battery pack is composed of many small batteries connected in series. During the working process, it will generate high heat, which seriously affects the battery life. In order to release the heat in time, it is necessary to introduce a foam material with heat conduction function. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a foam material applied to a battery pack of a new energy vehicle, so as to solve the technical problem of poor heat conduction function of the current foam material. [0005] (2) Technic...
