Abstract

The invention discloses high-strength flame-retardant elastic fabric and a preparation method thereof, and belongs to the technical field of fabric. The high-strength flame-retardant elastic fabric mainly comprises the following raw materials: red phosphorus flame-retardant master batch, wherein the red phosphorus flame-retardant master batch mainly comprises red phosphorus, magnesium hydroxide and aluminum hydroxide; an epoxy resin flame retardant, wherein the epoxy resin flame retardant comprises epoxy resin, a flame-retardant curing agent and an active flame-retardant diluent; polyurethane; plant fibers; viscose fibers; hollow polyester fibers; and an antibacterial agent. By adding the red phosphorus flame-retardant master batch, the flame-retardant effect of the fabric can be improved; the epoxy resin is matched, the cured phosphorus-containing flame-retardant epoxy resin has high glass transition temperature and good thermal stability and flame retardance; and meanwhile, and moisture generated when magnesium hydroxide is heated can be formed into a water film on the surface of the fabric under the action of polyurethane with good hydrophobicity, so that the flame-retardant effect is further improved.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a high-strength flame-retardant elastic fabric and a preparation method thereof. Background technique [0002] Fabric is the material used to make clothing. Most of the high-quality and high-end fabrics have the characteristics of comfortable wearing, sweat-absorbing and breathable, drape crisp, noble vision, and soft touch. With the continuous advancement of science and technology, people's living standards have been greatly improved. People have higher and higher requirements on the performance of clothing fabrics. In addition to paying attention to the color and style of clothing, people pay more and more attention to the comfort and safety of clothing. [0003] Existing fabrics are easily exposed to open flames during use, causing the fabrics to be flammable, thereby affecting use and posing potential safety hazards. Therefore, the present invention provides a high-strength f...
