Abstract

The invention relates to the fields of manufacturing and application of heat-resistant, heat-insulating, flame-retardant and high-temperature expansion materials, specifically to a hydrogel with fireproof and cooling functions and a preparation method thereof. The hydrogel comprises the following components in parts by mass: 0.05-20 parts of a hydrogel thickening agent, 5-35 parts of a freezing point depressant, 1-30 parts of an expanded foam material, 1-15 parts of an expanded flame retardant, 0.01-1 part of a foaming agent, 1-15 parts of a gas generating agent and 0.01-1 part of a bactericide. The hydrogel provided by the invention has the following innovations: when the hydrogel directly acts on the surface of a comburent, the hydrogel can be adhered to the surface of the comburent; meanwhile, foams can be generated on the surface of the comburent and contain water, so the water can be sealed in the foams to continuously exert cooling and fire extinguishing effects; after the wateris dried, an expansion flame-retardant layer can be formed to provide continuous heat-insulation and flame-retardant functions; and the functions of fire extinguishing, cooling, heat insulation and fire reburning prevention are achieved.

Description

technical field

[0001] The invention relates to the fields of manufacture and application of heat-resistant, heat-insulating, flame-retardant and high-temperature expansion materials, in particular to a fire-resistant thermal insulation gel with flame-retardant, heat-insulating and cooling functions and a preparation method thereof. Background technique

[0002] Lithium battery is currently the most advanced and fastest-growing civil chemical energy, and has become the preferred supporting power supply for high-end products such as mobile phones, notebook computers, and digital equipment. However, lithium batteries are also dangerous during use and transportation, which may be fatal or even lead to a disaster.

[0003] According to the US Federal Aviation Administration (FAA), between 1991 and 2014, there have been 144 accidents related to "smoke, fire, extreme heat or explosion" related to batteries. There have also been many lithium battery combustion accidents in China d...
