Description
Technical field
The present invention relates to a kind of soft wet method water-proof air-moisture-permeable urethane resin and preparation method thereof, belong to urethane preparation field.
Background technology
Raising day by day along with people's living standard, functional clothing fabric receives increasing concern, comprises water-proof breathable properties, ventilative thermal diffusivity, keep warm, moisture absorbing and sweat releasing property, wear-resisting tear strength, Antistatic radiation-proof, antibacterial deodourizing anti-mosquito property etc.Wherein water-proof breathable properties fabric refers to that fabric is in wearing process, and water does not soak into fabric under certain pressure, and the sweat that human body distributes etc. can be transmitted to the external world by fabric with the form of water vapour, keeps wearer dry and comfortable, comfortable.
People adopt the technology such as lamination, coating, high-density fabric to improve the waterproof and breathable performance of fabric, wherein fabric coating technology is one of the most frequently used method, coating for proofed breathable fabric has polyvinyl chloride, polyethylene, neoprene latex and other various synthetic rubber etc. at first, they have good water resistance, but moisture-penetrable ventilated poor performance, while wearing this type of clothes activity, a large amount of sweat cannot be discharged with water vapour form, at inner, form water of condensation, human body has the discomfort such as sticky wet, stuffy, thereby wear behavior awaits further raising.
And take film and the coating that urethane is raw material, can have dexterously waterproof and these two functions of ventilation property concurrently, and keep its original excellent properties.Urethane resin generally by polyisocyanates, polyvalent alcohol and small molecule chain extender (as water, small molecules polyvalent alcohol, polyamine) etc. for raw material synthetic, there is unique block molecule structure, can, by regulating the component proportions of urethane soft or hard section to change its elasticity, hardness, wetting ability etc., design as required the different product of performance.Its goods have unrivaled characteristic, as: unique cohesiveness, wettability, snappiness, wear resistance, glossiness etc.
Urethane resin is divided into wet method resin and dry method resin by processing mode, and dry method resin is divided into again surface layer resin and bottom (bonding) resin, and underfill resin layer is divided into again a liquid type, binary liquid shape and 1.5-liquid type.The difference of one liquid type and binary liquid shape resin is: a liquid type does not need to use solidifying agent (bridging agent, linking agent), and binary liquid shape resin can not be used separately, must be used in conjunction with solidifying agent, and 1.5-liquid type is to use on a small quantity bridging agent.Wet method resin is generally only used DMF as solvent, and dry method resin can be used the organic solvents such as DMF and toluene, ethyl ester, butanone.
Yet the polyurethane coating that domestic market is conventional, is mostly foreign enterprise's exploitations such as toray, U.S. 3M, Mitsubishi, use cost is higher.As the EntrantG-II of toray company research and development, by the cellular film of double-deck PU of different densities, formed, its Water Vapour Permeability reaches 8000g/m
2.24Hr, can intercept from 100 to 500 microns of the sizes (from drizzle to down-pour) of raindrop.
