Abstract
The invention relates to a preparation method of flame retardant PP (polypropylene) non-woven fabric. The non-woven base fabric obtained by a melt blowing method is subjected to flame retardant finishing. The preparation method comprises the following steps: preparing flame retardant slurry from the following components in percentage by mass: 62 to 73 percent of water, 18 to 22 percent of polyacrylic acid, 6 to 12 percent of decabromodiphenylethane, 2 to 4 percent of Sb2O3 and 0.5 to 1 percent of a silane coupling agent; pouring the flame retardant slurry into a slurry barrel with a stirring device, making the non-woven base fabric pass through a pressure roller and a slurry feeding roller, and transferring the slurry in a slurry groove to the base fabric through a screen frame by using the slurry feeding roller; placing the base fabric which is coated with the slurry between two rubber pressure rollers of a roller press for extruding to remove excessive slurry; finally, drying the base fabric to obtain the flame retardant non-woven fabric. The preparation method is simple in process, convenient to operate, and environmental friendly; the selected decabromodiphenylethane is a high-efficiency brominated flame retardant, and has the characteristics of high bromine content, high thermal stability, low toxicity and the like; meanwhile, the decabromodiphenylethane and the added Sb2O3 have a synergistic flame retardant effect, so that the prepared non-woven fabric has a good flame retardant effect.
Description
technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to the technical field of preparing PP flame-retardant non-woven fabrics. Background technique: [0002] Non-woven fabric is a kind of non-woven fabric formed by directly using polymer chips, short fibers or filaments to form fibers through airflow or mechanically, and then undergo spunlace, needle punching, or hot rolling reinforcement, and finally finish finishing. . Compared with traditional textile fabrics, it has the characteristics of short process flow, fast production speed, high output, low cost and wide application. It is widely used in medical and health care, home decoration, automobile industry, clothing accessories and other fields. With the improvement of people's living standards and the enhancement of safety awareness, the flame retardancy of non-woven fabrics has increasingly become the focus of attention. [0003] Polyester, nylon, polypropylene (PP) ...
