Problems solved by technology

[0003] In the chemical industry, because it contains a large amount of dangerous chemicals, if it is not stored properly or used improperly, it will easily explode, causing casualties; These toxic gases will seriously affect the health. In addition, when the staff conduct chemical experiments or carry chemicals, some strong acids and alkalis or corrosive liquid chemicals will inevitably adhere to the clothes. In severe cases, these are corrosive The liquid chemicals in the chemical industry will penetrate into the clothes, directly reach the skin, and cause the skin to rot, etc. Therefore, for the work clothes of the chemical industry, it is necessary to have the function of absorbing odor and isolating corrosive products while meeting high flame retardancy

Abstract

The invention discloses a flame-retardant composite fabric and a preparation method thereof. The composite fabric is formed by bonding an inner-layer fabric and an outer-layer fabric; the outer-layer fabric is composed of an aerogel heat-insulating coating, a blended textile layer and a flame-retardant heat-insulating coating, the blended textile layer is arranged between the aerogel heat-insulating coating and the flame-retardant heat-insulating coating, and the aerogel heat-insulating coating is close to the inner-layer fabric. The inner-layer fabric is formed by blending 30 to 40 parts of aramid 1313 fibers, 20 to 30 parts of pure cotton fibers and 40 to 50 parts of activated carbon fibers; the blended textile layer is formed by blending 30-40 parts by weight of basalt fibers, 20-30 parts by weight of cotton fibers and 30-40 parts by weight of polytetrafluoroethylene fibers; the aerogel heat-insulating layer and the flame-retardant heat-insulating coating respectively coat on the two surfaces of the blended textile layer to prepare the outer-layer fabric, and then the outer-layer fabric and the inner-layer fabric are laminated and bonded to prepare the composite fabric; and the composite fabric has extremely high flame retardance, adsorbability, air and moisture permeability and the like.

Description

technical field [0001] The invention relates to the field of flame-retardant materials, in particular to a flame-retardant composite fabric and a preparation method thereof. Background technique [0002] Flame-retardant composite fabrics refer to fabrics that can prevent the fabric itself from being ignited or slow down and stop burning when it comes into contact with flames or hot objects. It is suitable for use in places with flammable and explosive substances and fire hazards. [0003] In the chemical industry, because it contains a large amount of dangerous chemicals, if it is not stored properly or used improperly, it will easily explode and cause casualties; at the same time, because most chemicals will volatilize toxic gases, if workers are exposed to These toxic gases will seriously affect the health. In addition, when the staff conduct chemical experiments or carry chemicals, some strong acids and alkalis or corrosive liquid chemicals will inevitably adhere to the c...
