Abstract

The invention discloses low-smoke halogen-free flame-retardant gum-dipped elastic cloth and a preparation method of the cloth, and belongs to the technical field of special fabrics. The low-smoke halogen-free flame-retardant gum-dipped elastic cloth comprises flame-retardant fiber base cloth and a flame-retardant layer bonded onto the two side surfaces of the flame-retardant fiber base cloth, wherein the flame-retardant fiber base cloth is prepared by knitting or non-weaving high-strength flame-retardant polyester fibers, high-strength flame-retardant nylon fibers or glass fibers, and the flame-retardant layer comprises the following raw materials by weight: 80-300 g of flame retardant, 20-100 g of polymer, 100-500 g of solvent and 2-20 mg of defoamer. The low-smoke halogen-free flame-retardant gum-dipped elastic cloth has excellent flame retardance and outstanding strong force capable of being against the influence of an external force, is not easily broken and has ideal elasticity and softness as well as sealing and oxygen isolating effects; and the process steps in the provided method are short and have no strict requirements on equipment, so that the technical effect of the low-smoke halogen-free flame-retardant gum-dipped elastic cloth can be guaranteed, and the industrial large-scale production requirements can be met.

Description

technical field

[0001] The invention belongs to the technical field of special fabrics, and in particular relates to a low-smoke, halogen-free, flame-retardant, rubber-dipped elastic cloth, and also relates to a preparation method of the low-smoke, halogen-free, flame-retardant, rubber-dipped elastic cloth. Background technique

[0002] The low-smoke, halogen-free and flame-retardant impregnated cloth mentioned above is mainly, but not limited to, used as wrapping tapes for wires and cables. and fire protection.

[0003] As we all know, in building fire accidents, the probability caused by wires and cables accounts for nearly 40%. In particular, about two-thirds of the casualties in fire accidents are caused by secondary injuries. The poisonous and harmful gas released by the cable during the burning process suffocates and dies. Therefore, the flame retardancy of wires and cables has always been concerned by people.
