Description

Technical Field

[0001] This invention belongs to the field of insulation materials technology, and relates to a flame-retardant and fireproof cloth for high-temperature insulation of power batteries and its preparation method. Background Technology

[0002] In recent years, with the booming development of the new energy vehicle industry, the market has placed much higher demands on the range and charging efficiency of power batteries. Therefore, high rate capability, high capacity, and good cycle performance are the main development trends of lithium batteries. However, as the energy density of lithium-ion power batteries continues to increase, while battery range is extended, incidents of spontaneous combustion and explosion of lithium-ion batteries are also becoming more frequent. Thermal runaway can occur under conditions such as overcharging, short circuits, high temperatures, and impacts, instantly releasing a large amount of heat and causing fires or even explosions, resulting in huge losses for related companies and users.

[0003] Therefore, automakers are paying increasing attention to thermal management materials for power batteries, especially fire-resistant and high-temperature insulating materials that can be wrapped inside, hoping to slow the spread of flames and give relevant personnel enough time to react and take measures; at the same time, in the event of thermal runaway of the power battery, the high-temperature combustion will reduce the risk of short circuits in electronic equipment circuits and avoid greater losses.

[0004] CN115073921 A discloses a method for coating silicone rubber foam with a ceramizable flame-retardant coating and its preparation process: silicone rubber comprises 100 parts by mass, fumed silica comprises 5-20 parts by mass, ceramizable filler comprises 5-20 parts by mass, flame retardant comprises 5-20 parts by mass, platinum inhibitor comprises 0.5-2 parts by mass, and platinum catalyst comprises 0.5-2 parts by mass; in step S2, liquid silicone rubber comprises 100 parts by mass, carbon black comprises 10-20 parts by mass, ammonium polyphosphate comprises 10-40 parts by mass, ceramizable filler comprises 20-30 parts by mass, and curing agent comprises 0.5-2 parts by mass. Its flame-retardant effect is excellent and suitable for the lightweight requirements of the new energy field; however, the rapid increase in volume after expansion will inevitably cause damage to other components, and the presence of pores prevents it from maintaining the insulation performance at room temperature at high temperatures.

[0005] CN113829701A discloses a ceramicized flame-retardant and heat-insulating fireproof material, its preparation method, and its application. The rubber composition comprises the following raw material components in parts by weight: 30-40 parts of silicone rubber, 15-30 parts of ceramic-forming filler, 15-22 parts of additive filler, 15-21 parts of flame retardant, and 1-6 parts of fluxing agent. The additive filler comprises a combination of diatomaceous earth, wollastonite, calcium carbonate, and fumed silica. While exhibiting good flame retardant properties, its high-temperature ceramicization ensures high-temperature insulation performance. However, its thickness exceeds 0.5 mm, making it unsuitable for applications requiring a thickness less than 0.2 mm while maintaining fire resistance. Furthermore, it is not suitable for ultra-thin, wound-like applications within batteries.

[0006] CN116004129A discloses a ceramicized composite tape for fireproof and high-temperature insulation of power batteries, its preparation, and its application: its ultra-thin thickness of 0.15-0.5mm ensures that it can be wound onto battery components; it can be ceramicized at a high temperature of 600-1000℃ to form a dense, non-porous ceramic body. While it can be ceramicized at high temperatures and achieve a thickness of 0.15-0.5mm, it still cannot meet customers' requirements for even thinner thicknesses, and it is prone to delamination from glass fiber after ceramicization, making it fragile in confined spaces.

[0007] Therefore, it is desirable to develop a flame-retardant and fireproof material for high-temperature insulation of power batteries, which not only has a small thickness but also excellent flame-retardant properties. Summary of the Invention

When used in power batteries, it can not only slow down the spread of flames and play a role in high-temperature insulation, but also will not crack, bulge, delaminate, peel or fall off after high-temperature use.
