Definitions
- the present invention relates to a porous laminate excellent in separation of contaminants and water.
- Patent Document 1 discloses separation of contaminants by a reverse osmosis membrane.
- membrane distillation As a method other than the reverse osmosis membrane, membrane distillation can be mentioned (for example, Patent Document 2).
- the present invention has an object to provide a laminate useful as a separation membrane for membrane distillation, which is capable of concentrating pollutants to a high concentration and reducing heat loss associated with separation of pollutants.
- One aspect of the present invention has a supporting substrate having communicating pores, and a porous resin layer having communicating pores, which is laminated on at least one surface of the supporting substrate, It relates to a laminate in which the resin layer comprises porous particles.
- the laminate may have a porosity of between 50% and 90%.
- the 50% particle size of the porous particles may be 1 ⁇ m to 50 ⁇ m.
- the pore diameter of the peak value in the pore diameter distribution of the porous particles measured in the range of 2 nm to 200 nm may be 5 nm to 150 nm.
- the thermal conductivity of the porous particles may be 0.05 W/m ⁇ K or less.
- the pore diameter of the peak value in the pore diameter distribution of the laminate measured in the range of 15 nm to 300 ⁇ m may be 150 nm to 600 nm.
- the thermal conductivity of the laminate may be 0.01 to 0.13 W/mK.
- the surface roughness (Ra) of the porous resin layer may be 60 to 100 as observed by an atomic force microscope.
- the contact angle of the porous resin layer may be 75° or more.
- the supporting substrate may have a basis weight of 1 to 500 g/m 2 and a thickness of 0.05 mm to 1 mm.
- a laminate useful as a new separation membrane which can concentrate pollutants to a high concentration, suppress heat loss, and treat a large amount of pollutants.
- the laminate of the present embodiment has a supporting base material having communicating pores, and a porous resin layer having communicating pores laminated on at least one surface of the supporting base material.
- the porous resin layer contains porous particles.
- the type of the resin material forming the porous resin layer is not particularly limited, but nylon 66, polyacetal, polycarbonate, polytetrafluoroethylene, polyvinylidene fluoride, polyphenylene oxide, polystyrene, polybutadiene, polyethylene, polypropylene, polyvinyl chloride, polyamide, It may be at least one resin selected from the group consisting of a polyimide acrylic resin, an epoxy resin, a silicon resin, a phenol resin, a urea resin and a melamine resin, and is a copolymer of two or more of these resin precursor monomers. It may be a polymer.
- Polytetrafluoroethylene, polyvinylidene fluoride, polyethylene, and polypropylene are easy to apply the stretching method, the non-solvent phase separation method, etc., which are widely used as the method for producing the porous resin layer, and thus the porous resin layer can be easily formed. It can be obtained and is preferable.
- the porous particles are not particularly limited, but include styrene-divinylbenzene-based crosslinked polymer particles, methacrylate-based crosslinked polymer particles, polyvinyl alcohol-based crosslinked polymer particles, phenol-based crosslinked polymer particles, porous silica particles, and porous acrylic particles.
- Porous organosilicon compounds are preferable because they have lower thermal conductivity than other materials.
- the material of the supporting substrate is not particularly limited, but examples thereof include aramid, cellulose, nylon, vinylon, polyester, polyolefin, rayon, polyamide, polyalkylene terephthalate, non-woven fabrics such as polyalkylene naphthalate, glass, and metal mesh. It can.
- polymer non-woven fabrics such as polyamide, polyester, polyolefin, nylon, polyethylene terephthalate, polyethylene, polypropylene, EVA (ethylene/vinyl acetate copolymer), nylon, polypropylene, polyethylene terephthalate are suitable for easy processing and molding. is there.
- the thickness of the supporting substrate is not particularly limited, but the thickness is preferably 0.05 mm to 1 mm, more preferably 0.08 mm to 0.3 mm.
- the thickness of the supporting base material used is 0.05 mm or more, the strength of the laminate is easily secured, and when the thickness is 1 mm or less, the amount of treatment per unit time can be increased, which is preferable.
- a preferred embodiment of the present invention also includes a case where two or more supporting base materials thinner than the above range are used in a stacked manner and the thickness is within the above range.
- the basis weight of the supporting substrate is not particularly limited, but the basis weight is preferably 1 to 500 g/m 2 , and more preferably 50 to 150 g/m 2 .
- unit weight refers to the mass per unit area of the supporting base material.
- the unit weight is the total unit weight of each layer.
- the laminate of the present embodiment can be suitably used as a porous membrane (separation membrane) for membrane distillation.
- Example 1 2 g of polyethylene glycol (manufactured by Sinopharm, PEG-400) and 3 g of lithium chloride (manufactured by Sinopharm) were added to 84 g of N,N-dimethylacetamide (manufactured by Sinopharm) and dissolved by stirring for 1 hour. 1 g of porous particles (airgel particles) were added to the solution and stirred for 1 hour to uniformly disperse the particles in the solution. Then, 10 g of polyvinylidene fluoride (manufactured by Solvay) was added, and the mixture was stirred at room temperature for 6 hours to be dissolved. The mixed solution was degassed under reduced pressure for 6 hours to obtain a coating liquid.
- polyethylene glycol manufactured by Sinopharm, PEG-400
- lithium chloride manufactured by Sinopharm
- the obtained coating liquid was dropped onto a PET non-woven fabric and applied with a film thickness of 1 mm using an applicator (manufactured by Schwan technology). After being exposed to the atmosphere for 10 seconds, it was immersed in deionized water for 24 hours. After the immersion, it was dried in an oven at 50° C. for 24 hours to obtain a porous laminate.
- Examples 2 to 8 were produced by the same method as Example 1 except that the compounding ratio of raw materials to be added and the 50% particle diameter of the porous particles were different. The compounding ratio and the 50% particle size are shown in Table 1.
- the coating liquid was coated on a metal plate at room temperature using a coating tool.
- the metal plate provided with the coating film was placed on another metal plate cooled with ice, the coating film became cloudy and became a solid coating film.
- the metal plate provided with the coating film was immersed in separately prepared cold water for 2 to 3 minutes, and the coating film was peeled from the metal plate.
- the peeled coating film was immersed in pure water for 12 hours to completely remove DMSO and then dried for 1 hour in a dryer set at 40° C. to obtain a white porous film.
- the film thickness was 0.5 mm.
- a porous membrane with low heat loss and high throughput can be produced by simply adding porous particles without changing the material, thickness and production method of the conventional nanoporous porous polymer membrane. It can be very useful.
