Abstract

The invention relates to a ceramizable heat-preservation fireproof coating comprising the following preparation raw material components in parts by weight: 5 to 30 parts of high-temperature-resistant silicon resin, 35 to 75 parts of heat-preservation filler, 5 to 15 parts of other functional fillers, 2 to 5 parts of auxiliaries and 50 to 500 parts of a diluting solvent. According to the coating, high-temperature-resistant silicon resin is used as a matrix, and the heat-preservation filler and other functional fillers are added, so that the mechanical property, high-temperature resistance, weather resistance and other properties of the coating are improved, and the coating can be subjected to ceramization reaction at the high temperature of 500 DEG C or above, so that the coating can bear high-temperature heating of 1400 DEG C and cannot be burnt through for a long time; and moreover, the coating has relatively low thermal diffusivity, can provide better heat preservation capability when the temperature is rapidly changed, has a good protection effect when being applied to the field of lithium ion batteries, and effectively solves the problems existing in a protection material in the prior art.

Description

technical field [0001] The invention relates to the technical field of thermal insulation and fire protection, and more particularly, to a ceramicized thermal insulation and fireproof coating. Background technique [0002] Lithium-ion batteries have the characteristics of high energy density and low power density, and are widely used in portable electronic devices and new energy vehicles. However, the battery performance of current lithium-ion batteries will drop sharply at low temperatures. For example, low temperature affects the three-dimensional structure of the positive electrode material and thus restricts the diffusion rate of lithium ions, and the compatibility between the electrolyte and the negative electrode and separator deteriorates at low temperature. Moreover, due to the high energy density of lithium batteries, once structural damage occurs, dangerous thermal runaway will occur, resulting in smoke, fire or even explosion, which seriously affects the safety of...
