Description

A kind of preparation of Intumescent Retardant System doping Ludox and its application
Technical field
The present invention relates to finishing functions of textile fabrics field, specifically provides one kind and Intumescent Retardant System is put on spinning The approach of fabric, gives Fire-proof Finishing Agents for Textile function.
Background technology
Terylene is a kind of thermoplastic fibre, when being heated, due to the temperature difference between its fusing point and ignition point, so that fibrous material is existed Soften before cracking, shrink, melt.Fused mass drippage departs from body can make flameout.The fire-retardant many of terylene are gone out from the thinking Send out, by promoting fused mass quickly drippage and self-extinguishment endowing terylene anti-flammability.First decompose when cotton fiber is heated, produce flammable gas Body, when there is enough oxygen, will burn, and ultimately form very small amount charcoal residue.Terylene is different in combustibility from cotton, makes Polyester cotton is produced " candle wick effect " when being heated, i.e., the charcoal that cotton burning is generated forms skeleton, during prevention terylene burning Fused mass is dripped, and the terylene of melting becomes fuel again, supports burning.
If by way of reducing molten drop, promoting into charcoal endowing terylene anti-flammability, can not only reduce that molten drop is caused two Secondary injury, also in order to solve, polyester-cotton blend is fire-retardant to provide a kind of thinking.
Intumescent Retardant System is the composite flame retardant system that the core elements such as a class set phosphorus, carbon, nitrogen are integrated, can be when being heated Expansion carbon-coating is formed by fire proofing surface.This carbon-coating can play a part of oxygen barrier, heat-insulated and anti-molten drop in condensed phase.Existing The technology Intumescent Retardant System method for applying mainly using coating on the textile, need to use binding agent, but binding agent is helped mostly Combustion, affects arrangement product flame retardant effect.Accordingly, it would be desirable to explore the side that Intumescent Retardant System is preferably put on effect textile Method.
Sol-gal process is a kind of newer method for fabric fire-retardant finishing.With silane as presoma, by colloidal sol Gel method can form one layer of Silica hydrogel thin film in fabric face.If in the colloidal sol that makes, flame-retardant system is adulterated wherein, is knitted After thing pads or impregnates the doping colloidal sol, drying and processing makes colloidal sol occur condensation reaction to form gel, here mistake in fabric face In journey, fire retardant is coated on gel network structure.According to having studied, in the flame-retardant system of some phosphorous-silicon, P elements master Promote during polymer combustion, to become charcoal, and element silicon can make formed layer of charcoal more stable, embody silicon-phosphorus cooperative flame retardant effect. Intumescent Retardant System is put on by fabric using sol-gal process, the combustion-supporting problem that binding agent may bring can be avoided, while sharp Acted on the cooperative flame retardant of silicon and Intumescent Retardant System, strengthen flame retardant effect.
