Abstract

The invention discloses an antiflaming electric arc-protection composite fabric. The antiflaming electric arc-protection composite fabric comprises a base fabric and a protection thin membrane layer; the base fabric layer is woven from polyimide, polysulfonamide, antiflaming modacrylic fibers, antiflaming viscose and POD fibers which are used as raw materials; the protection thin membrane layer is prepared from an antiflaming polyurethane emulsion, polyolefin elastomers, a halogen-free flame retardant, a thickening agent, a polyurethane crosslinking agent and a dispersion agent which are used as raw materials. According to the antiflaming electric arc-protection composite fabric, the thermal protection layer with an antiflaming function is further prepared on the surface of the base fabric, so that the obtained antiflaming electric arc-protection composite fabric has excellent permanent antiflaming performance, excellent antistatic performance and excellent electric arc protection performance.

Description

technical field [0001] The invention belongs to the technical field of special textile materials, and in particular relates to a flame-retardant and arc-proof composite fabric. Background technique [0002] Arc is a gas discharge phenomenon, the instantaneous electric spark generated by the current passing through some insulating medium (such as air). When the body is close to the high-voltage electricity but not in contact with it, the induction of the body acts as a bridge to form a jump, which can generate a high temperature of 29,400°C, which is about four times the temperature of the sun's surface, causing severe gas explosions and electrical burns . When the arc occurs, huge energy is released in a very short time, and the metal conductive element will vaporize and cause high-temperature steam and metal to expand rapidly. The rapid thermal expansion of air and metal vapor will cause a loud explosion and huge pressure. [0003] With the rapid development of my country...
