Above-mentioned pre-oxidation carbon fiber take polyacrylonitrile fibre as the carbon fiber that raw material is made, if by direct for polyacrylonitrile fibre heat meltable, can not keep its original fiber condition.During preparation pre-oxidation carbon fiber, polyacrylonitrile fibre be put in atmosphere or carry out Low Temperature Heat Treatment in other oxidizing atmospheres, be i.e. pre-oxidation treatment.Pre-oxidation treatment is the preproduction phase of fibers carbonization.Generally fiber is heated to about 270 DEG C under air, insulation 0.5h to 3h, the color of polyacrylonitrile fibre, by white yellowing, brown gradually, finally forms the pre-oxidation carbon fiber of black.Be polyacrylonitrile linear polymeric by after thermal oxide, be oxidized, pyrolysis, the series of chemical such as crosslinked, cyclisation form heat-resisting ladder type macromolecular structure, thus make pre-oxidation carbon fiber have the high temperature resistant and indeformable characteristic of chance high temperature.
Above-mentioned two-sided flame-retardant coating fabric by spinning, knit base, wholely to prepare afterwards;
Described spinning comprises fiber opening cleaning, then comb and parallel cotton fibers prior to spinning, card sliver, drafting, prepare rove, prepare spun yarn, winder, yarn steaming, doubling, double twisting, again yarn steaming, the step for preparing yarn and yarn is detected;
Described base of knitting comprises and carries out warping to yarn, and denting of then gaiting, looming weaving obtain grey cloth, and carry out physical property detection, mending to grey cloth and test the step of base;
Described rear whole comprise grey cloth washed, dry, shape, coating (the first coating), oven dry, clot, painting 2 times coating (the second coating) drying, finally obtain the two-sided flame-retardant coating fabric of finished product and the step of test package.
Compared with prior art, the two-sided flame-retardant coating fabric of one of the present utility model, there is the excellent performance of blocking laser beam and preventing slag from splashing, there is the characteristics such as fire-retardant, high temperature resistant, powerful high, good bandability simultaneously, protect safely and effectively for the staff in laser-cutting environment provides.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
Detailed description of the invention
Embodiment 1:
As shown in Figure 1, the two-sided flame-retardant coating fabric of one of the present embodiment, comprises the first coating 1 successively, and woven fabric layer 2 and the second coating 3, first coating 1 and the second coating 3 all adopt blacking and fire retardant glue to be mixed.The thickness of the first coating 1 is 1/2 of the thickness of the second coating 3.
Woven fabric layer 2 is pre-oxidation carbon fibers of the Dupont Kevlar and 40% of employing 60% is the thread BLENDED FABRIC of yarn, and yarn count is 26S/2.
Above-mentioned Kevlar, i.e. p-aromatic polyamide fiber-Fanglun l414, be a kind of aramid fiber reinforced composite of Dupont (DuPont) company development, E.I.Du Pont Company is called Kevlar to the brand that this registers.This composite combined high-strength and lightweight excellent speciality, under equivalent weight condition, be 5 dual intensities, 2.5 dual intensities of E level fiberglass, 10 dual intensities of aluminium of steel wire, be considered to fiber the strongest in the world.Kevlar has excellent heat resistance, can not only in the temperature range of negative 196 degree to positive 204 degree use and the change that do not have clearly or impairment continuously, also have simultaneously do not dissolve, fire line (not combustion-supporting), only can 427 degree of beginning carbonizations, temperatures as high 538 degree of excellent heat resistances contacted blink can be stood.Kevlar has low extension, high mode, fracture strength is high, temperature tolerance is high, not melting not combustion-supporting can the performance such as carbonization, high chemical resistance, high stability, low-gravity, excellent electrical insulating property.
Above-mentioned pre-oxidation carbon fiber take polyacrylonitrile fibre as the carbon fiber that raw material is made, if by direct for polyacrylonitrile fibre heat meltable, can not keep its original fiber condition.During preparation pre-oxidation carbon fiber, polyacrylonitrile fibre be put in atmosphere or carry out Low Temperature Heat Treatment in other oxidizing atmospheres, be i.e. pre-oxidation treatment.Pre-oxidation treatment is the preproduction phase of fibers carbonization.Generally fiber is heated to about 270 DEG C under air, insulation 0.5h to 3h, the color of polyacrylonitrile fibre, by white yellowing, brown gradually, finally forms the pre-oxidation carbon fiber of black.Be polyacrylonitrile linear polymeric by after thermal oxide, be oxidized, pyrolysis, the series of chemical such as crosslinked, cyclisation form heat-resisting ladder type macromolecular structure, thus make pre-oxidation carbon fiber have the high temperature resistant and indeformable characteristic of chance high temperature.
Above-mentioned woven fabric layer 2 is formed by Kevlar and the blending of pre-oxidation carbon fiber, has permanent fire retardant, high temperature resistant, powerful high characteristic.The positive and negative of above-mentioned woven fabric layer 2 by the first coating 1 and the second coating 3 coated, do not have hole completely, effectively block the laser beam leaked outside, shaded effect is very excellent.Above-mentioned first coating 1 and the second coating 3 add blacking in fire retardant glue, while not affecting other performance, be provided with better shaded effect.The good bandability of the present embodiment, can make the folded form shelter of accordion-like state in actual applications, effectively can weaken and stop the phenomenon that laser beam and welding slag splash.
Above-mentioned two-sided flame-retardant coating fabric by spinning, knit base, wholely to prepare afterwards;
Spinning comprises fiber opening cleaning, then comb and parallel cotton fibers prior to spinning, card sliver, drafting, prepare rove, prepare spun yarn, winder, yarn steaming, doubling, double twisting, again yarn steaming, the step for preparing yarn and yarn is detected;
Knit base to comprise and carry out warping to yarn, denting of then gaiting, looming weaving obtain grey cloth, and carry out physical property detection, mending to grey cloth and test the step of base;
Afterwards whole comprise grey cloth washed, dry, shape, coating (the first coating 1), oven dry, clot, painting 2 times coating (the second coating 3) drying, finally obtain the two-sided flame-retardant coating fabric of finished product and the step of test package.
The two-sided flame-retardant coating fabric of one of the present embodiment, there is the excellent performance of blocking laser beam and preventing slag from splashing, there is the characteristics such as fire-retardant, high temperature resistant, powerful high, good bandability simultaneously, protect safely and effectively for the staff in laser-cutting environment provides.
