In the figure: 1. an outer support layer; 2. an inner support layer; 3. an outer groove; 4. an inner side groove; 5. a sealing layer; 6. a wire mesh; 7. a fire barrier layer; 8. an insulating layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, a surface fabric with thermal-insulated fire prevention function, including outside supporting layer 1 and inboard supporting layer 2, outside supporting layer 1 and the facing surface of inboard supporting layer 2 are provided with outside recess 3 and inboard recess 4 respectively, and outside recess 3 corresponds each other with inboard recess 4, when producing, make outside supporting layer 1 and inboard supporting layer 2 closely laminate, and make outside recess 3 contrast each other with inboard recess 4, form the confined space, utilize this confined space to block the heat in the outside of outside supporting layer 1, reduce thermal transmission, the surface of outside supporting layer 1 is provided with flame retardant coating 7, be provided with woven wire 6 between flame retardant coating 7 and the outside supporting layer 1, the internal surface of inboard supporting layer 2 is provided with insulating layer 8.

Specifically, the sealing layer 5 is arranged on the inner surfaces of the outer groove 3 and the inner groove 4, the sealing performance of the outer groove 3 and the inner groove 4 is enhanced by arranging the sealing layer 5, the outer groove 3 and the inner groove 4 form a sealing space, and the heat transfer is blocked by the sealing space.

Specifically, the sealing layer 5 is a TPU film, the TPU film is prepared by processes of calendering, tape casting, film blowing, coating and the like on the basis of TPU granules, and is prepared by extruding and mixing MDI containing NCO functional groups, POLYOL containing OH functional groups and 1.4 BG.

Specifically, the outer support layer 1 and the inner support layer 2 are both PET synthetic fibers, which are commonly called "terylene", and have the following advantages: the strength is high, the dry strength is 4-7 cN/dex, and the wet strength is reduced; the extensibility is moderate and is 20 to 50 percent; the modulus is high, and in large varieties of synthetic fibers, the initial modulus of the terylene is the highest, and the value can reach 14-17 GPa, so that the terylene fabric has stable size, no deformation and lasting pleat; the rebound resilience is good, the elasticity of the product is close to that of wool, and when the product is stretched by 5 percent, the product can be almost completely recovered after unloading; the wear resistance is second to that of chinlon and is almost the same as that of other synthetic fibers; meanwhile, the fabric has acid and alkali resistance and microbial resistance, is not affected by moths, mold and the like, and does not need to be mothproof when being used for collecting the polyester clothes.

Specifically, the fireproof layer 7 is made of aramid synthetic fiber, the aramid is a flexible polymer, has good mechanical properties, has higher breaking strength than common terylene, cotton, nylon and the like, has higher elongation, soft hand feeling and good spinnability, can be produced into short fibers and filaments with different titer and length, is made into fabrics and non-woven fabrics with different yarn counts in common textile machinery, and meets the requirements of protective clothing in different fields through after finishing; the aramid fiber has excellent flame retardant and heat resistance, the limit oxygen index of the aramid fiber is more than 28, so that the aramid fiber can not be continuously combusted when the aramid fiber leaves the flame, the flame retardant property of the aramid fiber is determined by the chemical structure of the aramid fiber, and the aramid fiber is a permanent flame retardant fiber and can not reduce or lose the flame retardant property due to the use time and the washing times. The aramid fiber has good thermal stability, can be continuously used at 205 ℃, can still keep higher strength at the high temperature of more than 205 ℃, has higher decomposition temperature, can not melt or drip at the high temperature, and starts to be carbonized when the temperature is more than 370 ℃.

The heat-insulating layer 8 is a non-woven fabric woven by polyimide fibers, the polyimide fibers have good spinnability and can be made into textiles used in various special occasions, and the polyimide fiber heat-insulating protective clothing is comfortable to wear, good in skin adaptability, permanently flame retardant, stable in size, good in safety and long in service life due to the fact that the polyimide fiber heat-insulating protective clothing has high and low temperature resistance, flame retardance, no molten drop, self-extinguishing after leaving fire and excellent heat insulation performance, and is an excellent heat-insulating material due to the fact that the heat conductivity coefficient of the material is low compared with other fibers. The non-woven fabric woven by the polyimide fiber is the most ideal fiber material for manufacturing fireproof and flame-retardant clothes such as protective clothes of army, racing car and flying clothes, and fire-fighting protective clothes, and the nano fiber non-woven fabric can also be used for manufacturing comfortable and warm-keeping functional clothes.

The working principle is as follows: because the surface fabric all adopts the material that the quality is lighter, consequently, the whole quality of the fire control protective clothing of making alleviates greatly, it is more comfortable to make the fire fighter wear, help reducing the consumption of fire fighter's physical power for traditional fire control protective clothing of putting out a fire, and simultaneously, the surface fabric utilizes the sealed effect of TPU film increase air recess, improve whole thermal-insulated effect, flame retardant coating 7 and insulating layer 8 have superior fire prevention thermal-insulated effect, avoid the fire fighter to be heated and burn, and can block that point thorn form object punctures the protective clothing through wire mesh 6, greatly increased protective effect of protective clothing, make the fire fighter can be relatively safe put out a fire and save people, improve the efficiency of putting out a fire.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
