Abstract

The invention discloses an anti-electric-arc flame-retardant mixture and a manufacturing method thereof. The anti-electric-arc flame-retardant mixture comprises polyimide, aramid and modacrylic; the aramid is meta-aramid, para-aramid or a mixture of the meta-aramid and the para-aramid; the mass percentage of the polyimide, the aramid and the modacrylic in the total amount of the three materials isas follows: the polyimide: 2 to 40 percent, the aramid: 10 to 60 percent and the modacrylic: 20 to 70 percent. The existing form of the mixture is one or any combination of a fiber mixture, yarns, fabric, non-woven or clothing. Vertical combustion test is conducted by ASTM D6413-1999, the continuous combustion time is less than 2 seconds and the damaged length does not exceed 6 inches.

Description

technical field [0001] The invention relates to chemical industry, electric power or other labor protection fields requiring fire protection or arc protection, in particular to a flame retardant mixture suitable for providing high arc protection capability. Background technique [0002] Human activities are inseparable from electricity, and electricity has profoundly changed human life. While electricity brings convenience to human life, it also brings hazards such as electric shock and arc. In particular, arc accidents occur suddenly and cause great harm. The local high temperature can be as high as 20,000 degrees Celsius. The metal used as the electrode is instantly melted and cracked into the air, forming a local explosion effect. If the staff is unfortunately in the area of ​​the explosion effect, it will cause arc burns or even death in a very short moment. Due to the suddenness and transient nature of the arc, it is impossible for operators to wear arc-proof clothing...
