Problems solved by technology

[0002] Early gas masks mostly used natural rubber as the headband material, because it has excellent resilience, and as a headband material, the mask and the face are easier to fit and seal, but its flame retardancy is poor, and it cannot self-extinguish after catching fire. Manufacturers with flame retardant performance mostly use mesh cloth as the headband material, and its performance only meets some standards of GB2890-2009 or GB2626-2006, and it has not been clearly stated that it meets the requirements of GA 124-2004 "Positive Pressure Fire-fighting Air Respirators". Headband material according to flame retardant standard in "

Abstract

The invention discloses a flame-retardant headband material. The headband material comprises, by weight, 70-100 parts of natural rubber, 10-30 parts of chloroprene rubber, 5-20 parts of zinc oxide, 2-10 parts of magnesium oxide, 2-10 parts of stearic acid, 2-10 parts of sulfur, 1-5 parts of accelerant DM, 1-5 parts of accelerant M, 1-5 parts of accelerant NA-22, 20-50 parts of decabromodiphenyl ether, 15-40 parts of antimonous oxide, 1-5 parts of antiager D, 1-5 parts of antiager MB, 30-50 parts of argil, 5-15 parts of calcium carbonate and 5-15 parts of carbon black N220. The headband material conforms to the standard for mask headband materials after being inspected by GA 124-2004 Positive Pressure Air Breathing Apparatus and meets conditions after being authenticated through experiments, thereby starting to be produced in batch currently.

Description

technical field [0001] The invention relates to the field of gas mask cover body accessory materials, in particular to a flame-retardant headband material. Background technique [0002] Early gas masks mostly used natural rubber as the headband material, because it has excellent resilience, and as a headband material, the mask and the face are easier to fit and seal, but its flame retardancy is poor, and it cannot self-extinguish after igniting. Manufacturers with flame retardant properties mostly use mesh cloth as the headband material, and its performance only meets some standards of GB2890-2009 or GB2626-2006, and it has not been clearly stated that it meets the requirements of GA 124-2004 "Positive Pressure Fire-fighting Air Respirators". "The flame retardant standard headband material. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a headband rubber that can meet the physical and mechanical properties of t...
