Description

There is the double-component microporous membrane of Waterproof Breathable elastomeric property
Technical field
The present invention relates to a kind of double-component microporous membrane with Waterproof Breathable elastomeric property, belong to weaving face fabric technology neck Territory.
Background technology
Waterproof & Moisture Permeable Film of the prior art is mainly hydrophilic Waterproof & Moisture Permeable Film, utilizes what this thin film made to answer Closing fabric, its mechanism is to be contacted with fabric face by antiperspirant vapour, is delivered to the external world by hydrophilic group.This fabric exists Big problem is exactly: hydrophilic group adsorbed water molecule, makes fabric become the most thick and heavy, clammy, and human body dress has discomfort.Also There is a kind of micro-porous membrane being namely based on nanotechnology principle, wherein main with the micro-porous membrane of polyurethane and politef Thin film is main, and both thin film have different pluses and minuses, the micro-porous membrane of polyurethane have preferable waterproofing and moisture-penetration performances its Excellent spring, can adapt to different attaching process during the laminating of fabric, prevents fabric the best shape wrinkling, elastic Condition, in the motor process of high intensity the most out of doors, the fabric of joint part can occur stretching in various degree, the most this Thin-film material imparts elasticity and the adaptability that clothing are become reconciled, and also prevent the shape such as Film Tear in violent motor process Condition so that it is no matter can have the water resistance of excellence in which type of environment.And polytetrafluoroethylene film, owing to it is special Different microcellular structure (in netted) makes it have wind and water preventing, the water vapour permeability that pore type polyurethane film can not have, and is better than Traditional microporous polyurethane thin film, but its shortcoming it is also clear that, its elasticity of this material is substantially zeroed, the most this thin film Material either still all can not well adapt to face in the recombination process of fabric during the strenuous exercise of high intensity The material thin film damage that brought of stretching, easily causes water resistance and its decline with the bond properties of fabric.
Summary of the invention
It is an object of the present invention to provide a kind of double-component microporous membrane with Waterproof Breathable elastomeric property, this double-component micropore Thin film improves elasticity and adaptability, also avoids due to the dust in pore type polytetrafluoroethylene film layer absorption air, perspiration In the material such as salt, oils and fats cosmetics and detergent, it is achieved that keep stable waterproof for a long time and perspire vapour performance, Have simultaneously high intensity, do not absorb water, anti-wear performance.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of double groups with Waterproof Breathable elastomeric property Part microporous membrane, including pore type polyurethane film, polytetrafluoroethylene film, described pore type polyurethane film, polytetrafluoroethyl-ne Being bonded by adhesive layer between alkene thin film, the number of described polytetrafluoroethylene film hole per square inch is 85 ~ 9,500,000,000, hole The average diameter in hole is 0.2um ~ 10um；
Described pore type polyurethane film is scratched in silicon oil release paper and successively 80 ~ 150 by prefabricated polyurethane slurry The baking oven baking of degree thermograde, is cooled to room temperature again after reaching 150 degree and being incubated and obtains；
Described prefabricated polyurethane slurry is composed of the following components:
Polyurethane resin 100 parts,
Dimethylformamide 20 ~ 25 parts,
Toluene 32 ~ 35 parts,
Butanone 12 ~ 15 parts,
Microspheres 8 ~ 9 parts,
Isosorbide-5-Nitrae one butanediol 1.5 ~ 2.5 parts；
Polyacrylamide 1.2 ~ 1.8 parts；
Acrylate 0.3 ~ 0.5 part,
Organosiloxane emulsion 0.2 ~ 0.3 part.
The technical scheme improved further in technique scheme is as follows:
As preferably, the volume of described polytetrafluoroethylene film Hole accounts for the 80 ~ 90% of polytetrafluoroethylene film volume.
As preferably, the mass ratio between described polytetrafluoroethylene film and pore type polyurethane film is 1:6.5 ~ 7, thick Degree ratio is 1:0.3 ~ 0.6.
As preferably, the baking oven baking of described 80 ~ 150 degree of thermogrades specifically includes with the next stage:
The described first stage: under conditions of 80 DEG C, and carry out under the air atmosphere of low speeds flow；
Second stage: under conditions of 90 DEG C, and carry out under the air atmosphere of middling speed flowing；
Phase III: under conditions of 110 DEG C, and carry out under the air atmosphere of strong speed flowing；
Fourth stage: under conditions of 140 DEG C, and carry out under the air atmosphere of low speeds flow.
As preferably, described microspheres is akzonobel company microspheres, and it has resilient shell and is contained within The low-boiling point materials such as iso-butane, propane, pentane.
Owing to technique scheme is used, the present invention compared with prior art has following advantages and an effect:
1. the present invention has the double-component microporous membrane of Waterproof Breathable elastomeric property, can avoid owing to pore type gathers The materials such as the dust in tetrafluoroethene thin layer absorption air, salt, oils and fats cosmetics and detergent in perspiration, it is achieved that Keep stable waterproof for a long time and perspire vapour performance；Next, combine and have the hydrophilic layer of polyurethane refusing oil and polytetrafluoro Vinyl film layer, while improving external prevention rainwater performance, has and enhances the performance internally discharging human body antiperspirant vapour so that Fabric has more preferably comfort property and broader practice scope；Again, have greatly due to this double-component thin-film material Measure uniform hole, and there is the hydrophilic microvoid polyurethane resin bed refusing oily type, thus be more beneficial for steaming from human body water The discharge of vapour, greatly reduces the moisture of residual thin polyurethane film surface, thus improves the wearability of coating fabric And wear dry and comfortable, most importantly substantially increase the elasticity of PTFE film material, make clothing clothes at high sharp movement With also there is under extreme condition good mechanical property.
2. the present invention has the double-component microporous membrane of Waterproof Breathable elastomeric property, for polytetrafluoroethylene film Particular combination, optimizes the formula of pore type polyurethane film, thus improves elasticity and adaptability, have simultaneously high intensity, Do not absorb water, anti-wear performance.
