A method of flame retarding comprising the steps of:

the method comprises the following steps: a user wears the flame-retardant jacket, the flame-retardant outer trousers, the flame-retardant pieces at the key parts, the middle fixing waistband, the head flame-retardant helmet, the hand flame-retardant sleeve and the foot flame-retardant shoes to enter a fire environment, and the flame-retardant jacket, the flame-retardant outer trousers, the flame-retardant pieces at the key parts, the head flame-retardant helmet, the hand flame-retardant sleeve and the foot flame-retardant shoes normally play a flame-retardant function;

step two: when the external heat is high, the non-hardened fireproofing mud absorbs the external heat and expands per se, and the fiber cloth layer, the non-woven honeycomb network, the first plastic cloth layer, the dry ice, the second plastic cloth layer, the filling air bag and the middle fiber cloth layer are extruded and attached to the body side;

step three: the self-low temperature of the dry ice keeps the temperature of the trunk to be in a low-temperature state, the dry ice is gradually gasified under the condition that the temperature of the external fire environment is higher, the low-temperature protection is provided, meanwhile, carbon dioxide overflows, and the invasion of the flame to the position of the trunk is slowed down.

Compared with the prior art, the invention has the beneficial effects that:

1. in the invention, when the external heat is high, the non-hardening fireproof mud absorbs the external heat and expands per se, the extrusion and lamination fiber cloth layer, the non-woven honeycomb network, the first plastic cloth layer, the dry ice, the second plastic cloth layer, the filling air bag and the middle fiber cloth layer are gathered towards the body side, and as the fire-retardant sheets at the key parts are sewn into small grids, even if in a gathering state, the sewing position can be bent to a certain degree, and the action of a user cannot be seriously influenced due to the expansion of the non-hardening fireproof mud; the dry ice has low self temperature and keeps the trunk temperature to be in a low-temperature state, and the dry ice is gradually gasified under the condition that the external fire environment temperature is higher, so that the carbon dioxide overflows while low-temperature protection is provided, and the invasion of flames to the trunk position is slowed down. The problem that the fire-retardant garment is provided with a zipper at the chest part and a cover cloth outside the chest part for putting on or taking off at present is solved, so that the fire resistance of the position is lower than that of other places, key organs related to life are positioned in the middle of a human body, and the safety coefficient is not enough; the front part and the rear part of the human body are in large contact with a heat source, and even if the human body is not directly attacked by fire, key organs are seriously damaged due to overhigh heat; and a zone which is difficult to invade by fire can be formed near the user, so that the temperature near the user and the invasion of the flame can be slowed down.

2. In the invention, the key part flame-retardant piece is arranged at the front and back positions of the flame-retardant garment when being worn, and the position of the key part flame-retardant piece is fixed by utilizing the connection characteristics of the first magic tape hair part, the second magic tape hair part and the magic tape hook part; after the length of the third adjusting belt is adjusted, the front and rear flame-retardant sheets at two key positions are fixed by a third fixing male and female buckle; then the middle fixing waistband is used for penetrating through the connecting bands at the two sides of the trouser waist and the outer part of the key part flame-retardant sheet, and then buckling and fixing are carried out. The whole operation process is relatively simple, the wearing time of the flame-retardant garment cannot be greatly prolonged due to the existence of the flame-retardant pieces at the key parts, and the garment is convenient to wear and take off.

3. In the invention, the flame-retardant jacket is worn firstly, then the flame-retardant outer trousers are worn, the waist of the trousers is positioned at the waist contraction region, the adjustable braces pass through the hands and move to the positions above the shoulders, the shoulder limiting belts are used for limiting and fixing, the connection integrity of the flame-retardant jacket and the flame-retardant outer trousers is improved, the condition that the flame-retardant outer trousers are overweight and slide is avoided, and compared with the situation that the waist is directly fixed in a very tight and elastic manner, the wearing time is shorter.

4. In the invention, when the flame-retardant coat is worn, the inner part of the coat is taken out, and a thumb passes through the thumb hole; when the flame-retardant outer pants are worn, the inner belt of the outer pants is taken out, and the inner belt part of the outer pants is wrapped at the positions of feet; the back collar tongue is arranged to be attached to the back neck position, the neck tightening cloth is pulled to pass through the front of the neck, and the collar is fixed by the connecting buckle; the flame-retardant helmet for the head, the flame-retardant sleeve for the hand and the flame-retardant shoes for the feet are worn subsequently, so that the condition of flame invasion caused by large gaps in the middle positions of wearing can be avoided, and the safety coefficient is improved.
