Abstract

The invention provides a fireproof thermal insulation material as well as a preparation method and application thereof. The fireproof thermal insulation material comprises a base layer and a coating layer which are attached to each other; the coating layer is prepared from a coating; the coating is prepared from the following components in parts by weight: 20-30 parts of raw rubber, 20-30 parts of a reinforcing agent, 40-60 parts of a flame retardant, 3-10 parts of a ceramic forming filler, 1-5 parts of a silane coupling agent and 1-3 parts of a vulcanizing agent; the preparation method comprises the following steps of kneading the raw rubber and the reinforcing agent to obtain a rubber compound A, kneading the rubber compound A, the flame retardant, the filler and optional catalyst and inhibitor to obtain a rubber compound B, mixing the rubber compound B with the vulcanizing agent to obtain a rubber compound C, coating any surface of the base layer with the silane coupling agent, and calendering and vulcanizing the surface, coated with the silane coupling agent, of the base layer and the rubber compound B to prepare the fireproof thermal insulation material. The fireproof thermal insulation material provided by the invention has better flame retardance, high temperature resistance, thermal insulation property, and good mechanical property and electrical property.

Description

technical field [0001] The invention belongs to the technical field of new energy batteries, and in particular relates to a fire-proof and heat-insulating material and its preparation method and application. Background technique [0002] With the development of society and the improvement of people's awareness of environmental protection, electric vehicles have received more and more attention. As the energy source of electric vehicles, the safety of batteries is particularly important. During the use of new energy vehicles, temperature has an important impact on the performance of the battery. The charging and discharging reaction of the battery occurs within a certain temperature. If the temperature is too high or too low, the battery will be difficult to work or the working efficiency will be low. Moreover, during the working process of the battery, with the occurrence of chemical reactions, the internal temperature of the battery is not equal to the ambient temperature,...
