Background
The waterproof and moisture permeable fabric is a novel textile fabric as one of composite fabrics, and when the air tightness and the water tightness of the fabric are enhanced, the unique air permeability of the fabric can enable water vapor inside the structure to be rapidly discharged, so that the structure is prevented from breeding mould, the human body is kept dry and comfortable all the time, the problems of ventilation, wind prevention, water prevention, heat preservation and the like are perfectly solved, and the fabric is a novel fabric which is healthy and environment-friendly. At present, the microporous membrane composite fabric is widely applied to the problems of water resistance, air permeability and the like, namely, the functional garment fabric is prepared by compounding the microporous membrane and the fabric through a binder.
The microporous membrane mainly comprises a polymer microporous membrane formed by stretching a high molecular polymer film and a nanofiber membrane prepared by utilizing an electrostatic spinning technology. The typical representatives of the polymer microporous membrane include a polytetrafluoroethylene microporous membrane, a polyurethane microporous membrane, a polyethylene microporous membrane and a polyacrylic resin microporous membrane, the polytetrafluoroethylene microporous membrane has excellent waterproof, moisture permeable, air permeable and windproof performances due to the special molecular structure, and C-F groups in the molecules endow the polytetrafluoroethylene with corrosion resistance. Compared with polytetrafluoroethylene microporous membranes, the corrosion resistance of polyurethane microporous membranes and polyacrylic resin microporous membranes is poor, and the nano-fiber microporous membranes manufactured by adopting an electrostatic spinning method have poor corrosion resistance if raw material fibers are not corrosion-resistant. Therefore, the improvement of the corrosion resistance of the composite fabric made of the microporous membrane has important significance.

Further preferably, the organic solvent includes any one of dichloroethane, ethyl acetate, and xylene.
The invention also provides a preparation method of the corrosion-resistant waterproof moisture-permeable composite fabric, which is characterized by comprising the following steps of:
(1) preparation of the corrosion-resistant coating: adding fluorine-containing polyacrylate and a curing agent into an organic solvent in proportion, mixing and stirring uniformly, adding nano titanium dioxide into the organic solvent to uniformly disperse the nano titanium dioxide to obtain corrosion-resistant treatment liquid, drawing a microporous membrane by a drawing roll to move, enabling the microporous membrane to pass through and be soaked in the corrosion-resistant treatment liquid, drying and rolling, wherein the drawing speed of the drawing roll is 50-80 m/min, the drying temperature is 100-120 ℃, and the time is 20-30 min;
(2) compounding the fabric: applying point-shaped glue on the fabric, and performing hot-pressing compounding on the fabric and the microporous membrane by using a glue point compounding method to prepare the polytetrafluoroethylene composite fabric, wherein the hot-pressing temperature is 120-180 ℃, the hot-pressing pressure is 0.2-0.4 MPa, and the hot-pressing time is 30-40 s.
Further preferably, the preparation method of the corrosion-resistant coating further comprises the step of dispersing the nano titanium dioxide in a silane coupling agent.
According to a further preferable technical scheme, in the step of preparing the corrosion-resistant coating, after the fluorine-containing polyacrylate and the curing agent are added into the organic solvent and uniformly stirred, a traction roller pulls the microporous membrane to pass through and soak in the fluorine-containing polyacrylate solution, the acetone solution or the silane coupling agent solution with the nano titanium dioxide dispersed is coated on the surface of the microporous membrane after drying, the microporous membrane is dried again and then wound, the traction speed of the traction roller is 50-80 m/min, and the drying temperature is 100-120 ℃.
In order to solve the problems that the corrosion resistance of the waterproof moisture-permeable composite fabric is poor and the waterproof moisture-permeable performance of the fabric is obviously reduced after the fabric is soaked by chemicals or corrosive liquids, the technical scheme of the invention is that before the composite fabric is manufactured, the corrosion-resistant coating treatment liquid is soaked or coated on a microporous membrane and dried, and the corrosion-resistant coating treatment liquid comprises 0.1-3% of fluorine-containing polyacrylate, 0.01-0.3% of curing agent, 0.05-0.6% of nano titanium oxide and 96.5-99.5% of organic solvent by mass percent. The fluorine-containing polyacrylate is a fluorine-containing resin, because a plurality of C-F chemical bonds with high bond energy exist in a molecular chain structure, the fluorine-containing polyacrylate has lower surface energy, stronger hydrophobicity and better solvent resistance and chemical corrosion resistance, compared with thermoplastic resins such as polytetrafluoroethylene, polyvinylidene chloride and the like, the fluorine-containing polyacrylate also has the advantages of good film forming property, good solubility and the like, and is mainly used for manufacturing anti-graffiti coatings, antibacterial adhesion surfaces, antimicrobial reproduction human body implantation medical devices and other fields at present.
Nanometer titanium dioxide is a very common nanometer filler, is widely applied to various modifications of polymer materials, such as toughening modification, puncture resistance modification, wear resistance modification of polymer films, viscoelastic modification of polymer materials and the like, and has a plurality of cases of mixing the nanometer filler with organic polymer materials to modify the corrosion resistance of coatings in research and development and manufacture of metal protective coatings. According to the invention, the nano titanium dioxide is added into the fluorine-containing polyacrylate, and the mixed solution is coated on the microporous membrane, so that the corrosion resistance of the microporous membrane is improved. The usage amount of the fluorine-containing polyacrylate is controlled to be 0.1-3%, the usage amount of the nano titanium oxide is controlled to be 0.05-0.6%, and more coating can be prevented from permeating into gaps of the microporous membrane by controlling the usage amounts of the polymer and the nano material in the corrosion-resistant treatment liquid and the manufacturing process of the coating, so that the gaps of the microporous membrane are blocked, and the moisture permeability of the microporous membrane is reduced.
The invention provides two manufacturing methods of corrosion-resistant coatings when preparing a composite fabric, and the optimal scheme is that nano titanium dioxide is uniformly dispersed in a solution mixed with fluorine-containing polyacrylate, then the solution is drawn by a drawing roll, a microporous membrane is soaked in the mixed solution, and the microporous membrane is dried. The wetting time of the microporous film is controlled by controlling the traction speed of the traction roller, so that the micropores of the microporous film are not blocked, and in addition, the temperature and the time of drying the coating are also very important parameters. In the technical scheme, in order to enable the titanium dioxide to be more uniformly dispersed in the solution mixed with the fluorine-containing polyacrylate, the preferable technical scheme is that the silane coupling agent is firstly adopted to treat the nano titanium dioxide, so that the nano titanium dioxide is uniformly dispersed in the silane coupling agent, then the silane coupling agent dispersed with the nano titanium dioxide is mixed into the fluorine-containing polyacrylate solution, the silane coupling agent is added, so that the nano titanium dioxide can be better dispersed in the solution, and on the other hand, the silane coupling agent is added to increase the bonding strength between the fluorine-containing polyacrylate and fibers in the microporous membrane, so that the coating is not easy to fall off.
In the preferable preparation method scheme of the corrosion-resistant coating, a traction roller is adopted to pull the microporous membrane and soak the microporous membrane into a fluorine-containing polyacrylate solution, and drying treatment is carried out. Preparing a nano titanium dioxide/acetone solution or a nano titanium dioxide/silane coupling agent solution, coating the solution containing the nano titanium dioxide on the dried microporous membrane, drying again and then rolling.
After the corrosion-resistant coating is soaked or coated on the microporous membrane, the corrosion-resistant coating can be filled into the microporous membrane due to high fluidity, and in the curing process, the fluorine-containing polyacrylate can generate a crosslinking reaction with a curing agent to generate a new substance and form a bonding point and a bonding network on the microporous membrane, so that micropores with very small pore diameters can be filled, and the porosity of the microporous membrane is reduced. However, because the fluorine-containing polyacrylate has stronger hydrophobicity, the addition of the nano titanium dioxide can increase the roughness of the surface of the coating, further improve the wettability of the microporous membrane, convert the hydrophobicity of the microporous membrane into super-hydrophobicity, and compound the microporous membrane under the comprehensive action of the pore diameter of the microporous membrane and the surface wettabilityThe waterproof performance, namely the water pressure resistance, of the fabric can be maintained at the level before the coating is not added. Due to the reduction of porosity, the moisture permeability of the composite fabric shows a trend of decreasing, but the variation is not large, and the moisture permeability can still be kept at 6000-11000 g/m2In the range of/24 h. The air permeability of the composite fabric is positively correlated with the aperture and porosity of the microporous membrane, and the air permeability of the composite fabric is obviously reduced along with the reduction of the porosity from the original 30L/m2The/s is reduced to 1-10L/m2Compared with the composite fabric which is not treated by the corrosion-resistant coating, the composite fabric has lower air permeability, can still meet the requirement of the fabric on air permeability, and has excellent windproof performance while maintaining a certain air permeability.
The introduction of the corrosion-resistant coating can not cause great change of waterproofness and moisture permeability of the waterproof moisture permeable composite fabric, and more importantly, the corrosion resistance of the polytetrafluoroethylene waterproof moisture permeable fabric can be increased, and the corrosion-resistant coating is mainly expressed in the following aspects that firstly, fluorine-containing polyacrylate has strong corrosion resistance, and treating fluid flows into a microporous membrane after being coated, so that a bonding network can be formed on the fiber surface of the microporous membrane, and the contact between the fiber and a chemical solvent and a corrosion-resistant material is prevented; secondly, the surface roughness of the microporous membrane coating is increased by adding the nano titanium dioxide, and the surface is changed from hydrophobicity to superhydrophobicity, so that the corrosion-resistant material is prevented from contacting with the fabric more effectively; and thirdly, hydroxyl on the surface of the nano titanium dioxide can chemically react with a group of the curing agent, so that the nano titanium dioxide in the coating is more uniformly distributed, and the addition of the nano titanium dioxide can also increase the compactness of the coating and further prevent the corrosion.
The invention has the advantages and beneficial effects that:
1. the composite fabric prepared by coating a treatment solution mixed with fluorine-containing polyacrylate and nano titanium dioxide on the surface of the microporous membrane, curing and compounding the treatment solution and the outer layer fabric through a binder has a good waterproof and moisture permeable effect, the water pressure resistance can be kept at 60-200 kPa, and the moisture permeable amount is 6000-11000 g/m2The air permeability is 1-10L/m within 24h2In the range of/s.
2. The composite fabric coated with the corrosion-resistant coating has good corrosion resistance, and after the composite fabric is soaked by strong acid and strong alkali, the waterproof performance and the moisture permeability and air permeability of the fabric are not greatly changed.
3. When the corrosion-resistant treatment liquid is coated, the traction speed of the traction roller is ensured to be within the range of 50-80 m/min, a better bonding network structure is formed on the surface of the microporous membrane by the fluorine-containing polyacrylate and the nano titanium dioxide, and the phenomenon that the micropores of the microporous membrane are blocked and the performance of the fabric is influenced due to the fact that more fluorine-containing polyacrylate or nano titanium dioxide is soaked due to too low traction speed is avoided.
4. The composite fabric coated with the corrosion-resistant coating also has a good antibacterial effect, and clothes made of the fabric can effectively prevent invasion of germs when being worn next to the skin.
