Problems solved by technology

As a representative of phosphazene flame retardants, hexachlorocyclotriphosphazene (HCCP) has high phosphorus and nitrogen content and excellent flame retardant properties, but its poor washability and high halogen content limit the use of HCCP in fabrics. Application in Flame Retardant Finishing
Due to the flame-retardant materials of halogen-based flame retardants, a large amount of toxic and corrosive smoke will be produced when burning, which will pollute and corrode the environment and the atmosphere.

Embodiment Construction

[0020] Below in conjunction with specific embodiment, further illustrate the present invention. The invention includes the preparation of epoxy resin / montmorillonite nanocomposite material and the synergistic effect of high polyammonium phosphate to prepare flame retardant finishing agent and flame retardant high temperature resistant finishing of hemp fabric. In the present invention, the epoxy resin / montmorillonite nanocomposite material is used as the carbon source, and the ammonium polyphosphate is used as the acid source and the gas source to form an intumescent flame-retardant system, and the finishing solution is attached to the hemp fabric through a padding method, so that the hemp fabric When the fabric is heated, the high ammonium phosphate in it decomposes to produce phosphoric acid and ammonia gas, in which the phosphoric acid reacts with the epoxy group of the epoxy resin to form a carbon layer. The presence of nano-montmorillonite makes the formation of the carbon...

Abstract

The invention discloses a finishing method of a flame-retardant and heat-resistant linen fabric. The method comprises organic treatment of montmorillonite, modification of the montmorillonite by a surfactant, preparation of an epoxy resin / montmorillonite nanocomposite material, preparation of a flame-retardant treatment liquid and flame-retardant treatment of the linen fabric. An intumescent flame-retardant system is prepared from the epoxy resin / montmorillonite nanocomposite material as a carbon source and high-polymer ammonium phosphate as an acid source and air source; the treatment liquid is attached to the linen fabric through a padding method; and the linen fabric can obtain excellent flame retardant property and high temperature resistance.

Description

technical field [0001] The invention relates to the field of flame-retardant finishing agents, in particular to a method for preparing flame-retardant and high-temperature-resistant linen fabrics. Background technique [0002] According to the production process and the introduction method of flame retardants, the flame retardant of textiles can be roughly divided into two types: flame retardant treatment of fibers and flame retardant finishing of fabrics. In recent years, the development trend of high-efficiency flame retardants for textiles is low toxicity, low smoke, low pollution and low corrosion. As a representative of phosphazene flame retardants, hexachlorocyclotriphosphazene (HCCP) has high phosphorus and nitrogen content and excellent flame retardant properties, but its poor washability and high halogen content limit the use of HCCP in fabrics. Applications in flame retardant finishing. [0003] Hemp fiber has the characteristics of fast moisture absorption and m...
