Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with drawings and Examples.
As shown in Figure 1, provided the structural representation of the utility model polyurethane composite membrane embodiment.Polyurethane composite membrane of the present utility model is mainly made up of substrate layer 1, bamboo-carbon fibre layer 6, porous polyurethane film 3 and protective layer 5.Bamboo-carbon fibre layer 6 is positioned at a side of substrate layer 1; Porous polyurethane film 3 and protective layer 5 are positioned at the opposite side of substrate layer 1.Between bamboo-carbon fibre layer 6 and substrate layer 1, be coated with polyurethane glue-line 7 with bonding both.Between substrate layer 1 and porous polyurethane film 3, be coated with silica gel layer 2, to reach the object that adheres to both.Between porous polyurethane film 3 and protective layer 5, be coated with silicon the third emulsion layer 4, to play the effect that adheres to both.
The thickness of bamboo-carbon fibre layer 6 is 50～80 μ m.Bamboo-carbon fibre material in bamboo-carbon fibre layer 6 is that to get mao bamboon be raw material, adopt pure oxygen high temperature and nitrogen to intercept calcining new technology and the new technology of time delay, more refinement and the honeycomb of micropore that bamboo charcoal is innately had, and then make with thering is the polyester modification section melt spinning of honeycomb microporous structure trend.Bamboo-carbon fibre has stronger antibacterial and bacteriostasis, can effectively reduce the breeding of avoiding in it of each bacterioid.Except this, bamboo-carbon fibre also has following benefit: the absorption affinity that (1) is superpower.Bamboo Charcoal Adsorption ability is the more than 5 times of charcoal, and the harmful substances such as PARA FORMALDEHYDE PRILLS(91,95), benzene, toluene, ammonia and dust can be brought into play absorption, decompose the effect of peculiar smell and smelly eliminating.(2) emitting far-infrared, heat accumulation thermal.Far infrared emissivity is up to 0.87, can heat accumulation thermal, and temperature rise speed is faster than common cotton fabric.(3) damping.High equilibrium moisture regain and water retention, given the function of bamboo-carbon fibre damping.(4) anion releasing.Bamboo-carbon fibre can be launched the anion of the concentration that is equivalent to field, countryside, is of value to health.(5) bamboo-carbon fibre contains potassium, calcium etc. and is of value to healthy mineral matter.
The thickness of substrate layer 1 is 370～670 μ m.Substrate layer 1 is TPU material.TPU material is thermoplastic polyurethane, has good wearability and elastic force, and except this, it also has certain resistance to antibiotic property, can be recycled, more environmental protection.The inside of substrate layer 1 is provided with multiple micropores.Micropore is existing through substrate layer 1 body, has again and is distributed in the surperficial of substrate layer 1.The average diameter of micropore is only hundreds of nanometer, and hydration gas is had to good general's property selected, and gets final product passing through of block water molecule, but allows passing through of gas molecule, and this makes to have good water-proof breathable properties.The density of the distribution of micropore is 40～500,000/square centimeter.What deserves to be explained is, those skilled in the art can know that how realizing substrate layer 1 arranges hole by prior art, for example the various of monomer (for example isocyanates and polyethers) of synthetic PU is poured in latticed mould into moulding at a certain temperature, the then demoulding.
The thickness of protective layer 5 is 30～50 μ m, for example, can be 30 μ m, 40 μ m or 50 μ m.Protective layer 5 is PTFE Filled with Carbon Fiber material.PTFE Filled with Carbon Fiber material is a kind of material obtaining in cavernous polytetrafluoroethylene (PTFE) with filled with carbon fibers.Carbon fiber has good mechanical stretching performance, the further wearability of reinforced TFE.
The thickness of porous polyurethane film 3 is 25～45 μ m.Porous polyurethane film 3 is to have many materials of nanometer level microporous 51, these nanometer level microporous 51 have specific size, liquid water and gaseous state hydrone are had higher selective, allow to pass through with the aqueous water of condensed state form, and prevention hydrone, this gives material with good moisture-inhibiting and water-resistance.In this example, two-layer porous polyurethane film 3 can make skin sweat distribute to external, stops outer 1 moisture endosmosis simultaneously.The preparation technology of porous polyurethane film 3 is specially: by the same PU resin quality in PU resin, 0.4～0.6% levelling agent and 0.4～0.6% help stripping agent be thoroughly mixed to form hybrid resin, by the quality meter of PU resin, 1～2% flatting silica is well-dispersed in organic solvent (by the quality in fire-type PU resin, 15～25% butanone, 15～25% toluene and 25～35%N, dinethylformamide forms) formation mixed liquor.Then, successively divide and be added to hybrid resin three times according to 30%, 30% and 40% addition.Then, glue is inserted and made in bubble machine foaming and form polyurethane foam, the condition foaming by control, reaches the size of the micropore of polyurethane foam.Finally, after polyurethane foam is coated in release liners, release liners is dried, obtains porous polyurethane film 3.
Silica gel layer 2 is to be formed by dry by the glue of organosiloxane composition, and it has preferably heatproof, chemical stability.Its thickness is 5～10 μ m.Silicon the third emulsion layer 4 for example, is formed by dry by silicone ingredients (organosiloxane) modified acrylic acid emulsion, and this emulsion has acrylic emulsion and organosilyl advantage concurrently.The thickness of silicon the third emulsion layer 4 is 2～6 μ m.The thickness of polyurethane glue-line 72 is 1～5 μ m.The thickness of polyurethane glue-line 7 is 4～8 μ m.The coating that polyurethane glue-line 7 forms through cold curing for polyurethane glue.Polyurethane glue is the glue that contains urethano and NCO in strand.Polyurethane glue, due to the isocyanates that contains strong polarity and carbamate groups, has very high reactivity.Great advantage is withstand shock vibrations and flexural fatigue, and peel strength is very high, and particularly resistance to low temperature is extremely excellent.
Polyurethane composite membrane of the present utility model has good water resistant, ventilative and wearability, has the wide using value of sending out and larger market prospects in clothes, rain gear field.
