A kind of high temperature resistant flame retardant composite fabric and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant and flame-retardant composite fabric and a preparation method thereof, which mainly include two steps: fabric preparation and composite fabric preparation, wherein the preparation steps of the composite fabric include: placing the fabric in a finishing solution, and then padding; The fabric after the padding treatment is pre-dried, baked, washed and air-dried in sequence to obtain a composite fabric; wherein, the preparation of the finishing solution includes the preparation of the solution, the preparation of the composite material, and the acid modification of the attapulgite properties, preparation of finishing liquid and other steps. The composite fabric provided by the present invention has good high temperature resistance and good flame retardancy; meanwhile, the fabric used in the present invention uses a specific finishing liquid, and the finishing agent is composed of polyurethane, hydrotalcite, chitosan, and attapulgite. Soil is used as the main raw material, hydrotalcite / chitosan composite material and modified attapulgite are prepared first, and then mixed with polyurethane. The preparation process is simple, the raw materials are common, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of fabric preparation, in particular to a high temperature resistant and flame retardant composite fabric and a preparation method thereof. Background technique [0002] Generally, composite fabrics refer to new materials formed by bonding textile materials with other materials. With the improvement of living standards, the styles and properties of fabrics have become rich and diverse; the use of composite fabrics not only ensures the diversity of fabric styles, but also makes the fabrics have properties such as flame retardant, antibacterial, and anti-ultraviolet. These properties are suitable for outdoor products. Such as tents and bags, which can greatly ensure the service life and safety of the product. [0003] Flame retardant and high temperature resistance are the performance indicators that composite fabrics often pay attention to. In the prior art, Patent 201910066474.9 discloses a method for proc...

Problems solved by technology

The bottom layer uses microporous polyurethane resin to prevent rainwater from conducting moisture to the coating surface. The middle layer and surface layer use hydrophilic polyurethane resin to add appropriate amount of organic and inorganic flame retardants. Under the condition of ensuring that the dry weight of each layer of coating is appropriate, While achieving high water pressure, the moisture permeability and flame retardancy of the fabric are also guaranteed; while the patent document CN113771454A discloses a flame-retardant composite fabric, the materials in the flame-retardant coating used in it are mixed directly, and it is difficult to exert the maximum effect. Flame retardant effect; patent document CN111188202A discloses a flame retardant and high temperature resistant composite fabric, which uses a phosphorus flame retardant, and the preparation process is relatively complicated; patent document CN102965798A discloses a flame retardant protective clothing fabric, which is only Using flame retardant viscose fiber, the flame retardant effect is not ideal
