Description
Technical field
The present invention relates to a kind of high-waterproof high-moisture-permeable flame-retardant coating fabric.
Background technology
In the market, adopt fire-retardant padding finishing and flame retardant coatings arrangement to the flame treatment of fabric, wherein the flame retardant coating arrangement not be owing to can influence the not performance of coat side of fabric, and better security and comfortableness are arranged, by increasing people is accepted.Advantages such as arrangement then has water absorbent fiber high density tissue, top finish and applying arrangement etc. to the Waterproof Breathable of fabric, and wherein top finish is because its good product performance, and technology is simple, and cost is lower and being widely used.
At present, the top finish technology that fire-retardant and Waterproof Breathable top finish are combined is comparatively rare on market.This mainly is because the interpolation of fire retardant can influence the water vapour permeability of fabric, and the Waterproof Breathable coating resin mostly is greatly inflammable, flammable resin, adding waterproof and wetting thoroughly itself is exactly the notion of two mutual contradictions, the high water proofing property and the high poisture-penetrability that will obtain fabric usually simultaneously are not easy to, and high waterproof, height are wet, fire-retardant thoroughly just to be not easy more and will reach simultaneously.
Common flame retardant coating mainly obtains anti-flammability by the infiltration of fire retardant glue in fabric structure, and therefore for thick and heavy fabric closely, the fire resistance behind the flame retardant coating is difficult to reach fire-retardant requirement.The disclosed technological means of Chinese patent communique CN1635211A, though can solve the not high problem of fire resistance behind the heavily fabric flame retardant coating, but increased the mechanical foaming operation, and resulting product does not possess waterproof and moisture permeability after the coating, and can only be used for has desired occasion to the fire resistance of fabric.
The production method of existing painted fabric with water-proof and drench qualities simutaneously mostly is wet type micro porous coating method or the dry type micro porous coating method of adopting, form one deck polyurethane micro-porous film at fabric face, solve contradiction between the Waterproof Breathable by control, thereby make fabric obtain waterproof and moisture permeability micropore size in the polyurethane micro-porous film.Therefore, these processing methods require than higher operation, and resulting product do not possess fire resistance, can only be used for that the waterproof and moisture permeability of fabric is had desired occasion.
Therefore, the top finish product that fire-retardant and Waterproof Breathable top finish are combined could satisfy promptly to the requirement to some extent of fabrics flame resistance performance, again the loomage water proof and moisture permeable performance there is desired special occasions, as the protective clothes and the protective device fabric of departments such as fire-fighting, metallurgy, oil, national defence, and the tent-like lining etc.The disclosed technological means of Chinese patent communique CN1107192A, though can give the fabrics flame resistance waterproof and moisture permeability, but it carries out the wet type coating with separation cloth earlier, makes fire-retardant wet micro-porous film, with the adhesive that contains fire retardant film is fitted on the fabric again.This coating and applying finishing technique complexity, operation requires high, and the recovery process of solvent is loaded down with trivial details in the wet-process coating process, and fire retardant interpolation kind is many, and addition is higher, and so the production cost height, economic benefit is on the low side.In addition, its employed halogen fire-retardant agent, antimony serial flame retardant all are subjected to the restriction of environmental regulation at present.
Summary of the invention
The object of the present invention is to provide a kind of high-waterproof high-moisture-permeable flame-retardant coating fabric and production method thereof that has high waterproof, high wet thoroughly, anti-flaming function simultaneously.
Technical solution of the present invention is:
A kind of high-waterproof high-moisture-permeable flame-retardant coating fabric includes the fire-retardant overlay of base cloth and high-waterproof high-moisture-permeable.The fire-retardant overlay of this high-waterproof high-moisture-permeable is the polyurethane non-porous layer, and this polyurethane non-porous layer can give fabric very high water proofing property.Employed fire retardant is a Halogen corpuscular type fire retardant in the fire-retardant overlay of this high-waterproof high-moisture-permeable.It is even that Halogen corpuscular type fire retardant is easy to mixed with resin, can prevent that the fabric coating face from producing the adhesion sense, add can reach the good flame effect on a small quantity, and environmental protection, cost is low.
The polyurethane non-porous layer is Hydrophilicrto polyether type and/or PAUR non-porous layer in the high-waterproof high-moisture-permeable flame-retardant coating fabric, this Hydrophilicrto polyether type and/or PAUR non-porous layer not only can give fabric very high water proofing property, and the hydrophilic radical on this polyurethane segment can give fabric very high moisture permeability, thereby makes fabric have high water proofing property and high poisture-penetrability simultaneously.Halogen corpuscular type fire retardant is the corpuscular type fire retardant for Halogen phosphorus system and/or nitrogen in the polyurethane non-porous layer.Halogen corpuscular type flame retardant particle diameter is less than 50 μ m, preferably less than 20 μ m.Particle diameter is too big, can influence the water pressure resistance and the moisture permeability of fabric.Base cloth is terylene and/or nylon, is preferably terylene.
A kind of production method of high-waterproof high-moisture-permeable flame-retardant coating fabric comprises the following steps:
