Embodiment 1

[0025] (1) Preparation of flame retardant adhesive solution: 6 kg of ammonium dihydrogen phosphate, a solubilizer composed of 0.5 kg of urea and 0.5 kg of ammonium chloride, added 81 kg of water and stirred evenly to form a flame retardant mixture, added while stirring For 12 kg of acrylate emulsion, add about 0.2 kg of defoamer to eliminate air bubbles, and add an appropriate amount of pH regulator until the flame retardant adhesive solution is neutral.

[0026] (2) 95 kg of PSA fibers and 5 kg of polyester fibers with a melting point of 110°C are evenly opened on the TEMAFA opener.

[0027] (3) The opened fibers are transported to the large bin mixing box by the airflow, and then transported to the coarse opening and loosening box through the corner nail curtain, and then transported to the fine opening and loosening box, and then enter the cotton storage box.

[0028] (4) The fibers of the cotton storage box are transported to the Truetzschler-Erko double-cylinder double-do...

Embodiment 2

[0033] Replace "0.5 kg of urea and 0.5 kg of ammonium chloride solubilizer" in Example 1 with "1 kg of urea", and the others are the same as in Example 1 to obtain the permanent flame-retardant, heat-insulating and warm-keeping polysulfonamide of Example 2 flakes.

Embodiment 3

[0035] Replace "0.5 kg of urea and 0.5 kg of ammonium chloride solubilizer" in Example 1 with "1 kg of ammonium chloride", and the others are the same as in Example 1 to obtain the permanent flame-retardant and insulating sulfonamide of Example 3. Thermal insulation batting.

Abstract

The invention discloses a polysulfonamide permanent flame-retardant heat-insulation warm-keeping fabric sheet which is prepared from the following raw material components in parts by weight: 90-100 parts of PSA fibers and 0-10 parts of low-melting-point fibers. After being prepared into a fiber net, the raw materials are treated by a flame-retardant adhesive solution to obtain the polysulfonamide permanent flame-retardant heat-insulation warm-keeping fabric sheet. The polysulfonamide permanent flame-retardant heat-insulation warm-keeping fabric sheet has a permanent flame-retardant heat-insulation warm-keeping function, also can be used for guaranteeing the fabric sheet to have a good high-temperature-resistant and flame-retardant effect and a washing-resistant effect, guaranteeing the elasticity and fluffy restoration after washing of the fabric sheet.

Description

technical field [0001] The invention relates to an aramid sulfone fiber flake and a preparation method thereof, in particular to an aramid sulfone fiber permanent flame-retardant, heat-insulating and warm-keeping flake and a preparation method thereof. Background technique [0002] In high temperature, electric arc, steel and other workplaces and ground combat areas, operators need to wear high temperature and flame retardant clothing when working. Especially when the temperature is lower in the peripheral environment or when the weather is cold, in addition to the high-temperature-resistant and flame-retardant clothes of the outer layer, it is also necessary to configure cold-proof clothing for the operating personnel. At present, most of the clothing thermal insulation materials used in the market are polyester spray-bonded cotton, down and other materials, which can also play a good role in thermal insulation. However, these materials have no flame-retardant function, an...
