Description
Technical field
The present invention relates to a kind of polyurethane resin for water proof and breathable clothing leather.
Background technology
Proofed breathable fabric is meant that fabric can flashing, wind proofing, again can perspire, ventilative, comfortable and easy to wear, in wearing process, make water under certain pressure, not soak into fabric, and the sweat that human body distributes etc. can be with the form of water vapour by fabric or be transmitted to the external world, and not between human body surface and fabric condensation gather, it is dry and comfortable, warm to keep wearing the author.People are to snugness of fit, and improving constantly of functional requirement impels us to adopt various new techniques to improve every performance of fabric.
The waterproof and breathable mechanism of fabric mainly contains following three kinds of modes:
One, be to utilize the difference between the diameter of the minimum diameter of water droplet and steam or air to realize, both adopted the longitude and latitude of fabric between interweaving hole or the aperture of fabric composite between the diameter of minimum diameter and steam or air, reach the purpose of waterproof and breathable, cotton fabric of ultra-fine high density fabric, extra-high-speed density etc. is arranged based on the fabric of the waterproof and breathable of this principle design.The ventilative type of this kind fabric belongs to the diffusion naturally of hole between yarn.High density fabric is because lightweight robust thin, and good permeability is soft, drape is good, windproof, is widely used on physical culture, the outdoors clothes.Main drawback is that water-repellancy is poor, because thread count is big, the tear resistance of fabric is poor, the necessary special processing of spinning, production cost height, processing difficulties.
Two, be to adopt aperture that microporous membrane makes film micropore (micro-pore diameter is greatly about 1nm) between water droplet and moisture, with film and the compound fabric waterproof airing function of giving of fabric.Thereby the micropore polymer film can with fabric by lamination or coating process and the compound complex body waterproof and breathable function of giving of fabric.The generation of micropore has multiple mode: can produce micropore by the two-way stretch to film, also can make between superpolymer and the filler and form hole dosing filler (as pottery) on the superpolymer, also can produce micropore, can also mechanical system utilization punching technology (as laser) make non-porous film generation space reach gas-pervious purpose by be separated (wet method of urethane).
Three, be to utilize the hydrophilic component of high-polymer membrane that the enough chemical group rank stone as water vapour molecule is provided, water molecules is because hydrogen bond and other intermolecular forces, at high humidity one side draught attached water molecule, be delivered to low humidity one side desorb by hydrophilic radical on the macromolecular chain, form ＂ absorption--diffusion--desorb ＂ process, reach gas-pervious purpose.Hydrophilic component can be the hydrophilic radical in the molecular chain or the hydrophilic component of segmented copolymer; Its water-repellancy comes from the continuity of film self film and bigger face tension force.Utilize film and fabric to carry out lamination/coating and give the fabric waterproof airing function.
At first, the superpolymer that is used for proofed breathable fabric has polyvinyl chloride, polyethylene, neoprene latex and other various synthetic rubber, they form a kind of continuous nonporous film and reach waterproof effect by being coated on fabric face, but its ventilation property is very poor, when wearing these type of clothes, a large amount of sweat can't discharge and at inner formation water of condensation, human body be produced glue wet damp vexed sense with the water vapour form.Up to 1969, U.S. W.I.Gore company develops the polytetrafluoroethylene film with waterproofing and moisture-penetration performances, and in the first PTFE film laminating fabric of successfully manufacturing experimently of 1976 annual rates, proof: be to have good water vapour permeability when fabric has favorable waterproof property, waterproof and ventilative may the unification and one, fabric this difficult problem that can waterproof but can not wet thoroughly has breakthrough finally.After this, Gore company constantly weeds out the old and bring forth the new, and to the improvement of first-generation product performance, has released the s-generation, third generation product, and market assessment is very good, and this has also excited the research and development of polymer film forming greatly.Except that Gore-Tex, it all is the film products that are polymerized with PTFE that brands such as Tekratex, Leetex, Microtex and Dennis TB are still arranged.1962, Baeyer (Bayer) was invented the hydrophilic polyurethane with vapor permeability in the laboratory.The 60-70 age in 20th century has begun the development of microporous polyurethane coated fabric and nonporous film laminated fabric, and this series products mainly contains: toray (Toray) EntrantGII of company film; The Thintech film of Minnesota Mining and Manufacturing Company; MIT's shape memory polyurethane film; U.S. Thoratec company " BIOU II " high-performance special polyurethane film.But these product price height.
Summary of the invention
Technical problem to be solved by this invention provides a kind of polyurethane resin for water proof and breathable clothing leather, and it has good moisture-permeability waterproof performance, and production cost is low.
For solving above technical problem, the present invention takes following technical scheme:
A kind of polyurethane resin for water proof and breathable clothing leather, its composition of raw materials comprises polyester polyol, polyether glycol, chainextender, isocyanic ester, organic solvent, chain terminator and oxidation inhibitor, described composition of raw materials also comprises Repone K, described polyester polyol is the polyoxyethylene glycol butyleneglycol hexanodioic acid copolyesters glycol of molecular weight 2000, described polyether glycol is the polyglycol ether of molecular weight 2000, described chainextender is an ethylene glycol, described isocyanic ester is 4,4-ditane-2-isocyanic ester, in the total mass of urethane resin, the mass content of above-mentioned each component is as follows:
