Technical Field

The utility model relates to the technical field of protective clothing fabrics, in particular to a heat-insulating flame-retardant high-temperature-resistant thermal protective fabric.

Background

The common flame-retardant fabric is generally formed by superposing and compounding multiple layers of flame-retardant materials, the more excellent flame-retardant fabric is made of aerogel materials, the aerogel is called xerogel, most of solvents are removed from the gel, so that the liquid content in the gel is much less than the solid content, or the medium filled in the space network structure of the gel is gas, and the appearance is solid, so that the aerogel is formed. Aerogel is a solid form, one of the world's less dense solids. The density is typically only 3 kilograms per cubic meter. Because of the extremely low density, the current lightest aerogels are only 0.16 milligrams per cubic centimeter, slightly less dense than air. As the aerogel is generally more than 80 percent of air, the heat insulation effect is very good.

The thermal protection suit is protection equipment capable of effectively protecting a wearer, has a good barrier effect, and can isolate the wearer from the external environment as much as possible; the thermal protective clothing is important equipment for protecting firefighters, the performance of the thermal protective clothing is directly related to the life, safety and health of the firefighters, the fabric of the thermal protective clothing is formed by multiple layers of composite materials in order to achieve the thermal protective effect, and the performance of the thermal protective clothing is directly related to the life, safety and health of a wearer. Traditional thermal protective clothing usually reaches the thermal-insulated index through increasing insulating layer weight and thickness, but this kind of mode has reduced the travelling comfort to a certain extent, has brought certain adverse effect in use.
