Claims (7)
1. The preparation method of the flame-retardant and arc-proof composite fabric is characterized by comprising the following steps of:
(1) carrying out vacuum treatment and nitrogen replacement on the reaction kettle for later use;
(2) weighing p-phenylenediamine monomer, adding the p-phenylenediamine monomer into an N, N-dimethylacetamide solvent, stirring until the p-phenylenediamine monomer is completely dissolved, slowly adding 3, 3- (m-benzene) diether dianhydride monomer and sodium methacrylate, continuously stirring until the p-phenylenediamine dianhydride monomer is dissolved, then adding the N, N-dimethylacetamide solvent again, slowly adding a 5-amino-2- (p-aminophenyl) benzimidazole solution after completely stirring, slowly heating to the temperature of 128-plus 135 ℃ in the nitrogen atmosphere, and stirring for reaction for 6-6.5 hours to obtain a viscous stock solution;
(3) filtering and vacuum degassing the stock solution, then carrying out dry spinning, solidifying and cleaning the obtained precursor, and then drying and hot-drawing to obtain the polybenzimidazole-containing polyamide fiber;
(4) and (3) blending the polyamide fiber containing polybenzimidazole, the meta-aramid fiber and the flame-retardant viscose to obtain the composite fabric.
2. The preparation method according to claim 1, wherein the molar ratio of p-phenylenediamine, 3- (m-benzene) diether dianhydride and sodium methacrylate is 1: 1.6-1.7: 0.3-0.5.
3. The method according to claim 1, wherein the mass ratio of 5-amino-2- (p-aminophenyl) benzimidazole to p-phenylenediamine is 1.3 to 1.5: 1.
4. the production method according to any one of claims 1 to 3, wherein the concentration by mass of p-phenylenediamine in the solvent is 25%.
5. The production method according to any one of claims 1 to 4, wherein the dry spinning has a spinning temperature of 280 ℃ and an extrusion rate of 8.0 mL/min.
6. The preparation method of claim 1 or 5, wherein the mass ratio of the polyamide fiber to the meta-aramid fiber to the flame-retardant viscose is 4: 8: 3.
7. use of the flame retardant and arc proof composite fabric prepared by the preparation method of any one of claims 1 to 6 in the preparation of flame retardant and arc proof protective clothing.
