Abstract
The invention discloses an osmotic membrane, which mainly consists of a thin film and a polystyrene resin macromolecular polymer, wherein the polystyrene resin macromolecular polymer consists of polystyrene resin, one or mixture of polyethylene and polyvinyl chloride, and one or mixture of trichloromethane or ethanol. The osmotic membrane provided by the invention has good air permeability, good water resistance and strong humidity resistance, and can be applied to the surface of a non-woven fabric.
Description
Technical field
The present invention relates to polymeric material field, relate in particular to a kind of well behaved permeable membrane, especially be applied to the surface of nonwoven.
Background technology
Nonwoven (English name: Non Woven) claim adhesive-bonded fabric again, be to constitute by fiber orientation or at random, be environment-friendly materials of new generation, have protection against the tide, ventilative, pliable and tough, light weight, not combustion-supporting, easy decomposition, nontoxic nonirritant, rich color, cheap, capable of circulation characteristics such as use again.Nonwoven does not have graticule, cuts out and sews all very conveniently, and light weight finalizes the design easily, is subjected to liking of manual fan deeply.
Nonwoven just carries out textile staple or long filament orientation or supports row at random because it is a kind of fabric that does not need to spin cotton and weave cloth and form, and forms fibre net structure, adopts methods such as mechanical, hot sticky or chemistry to reinforce then and forms.Simply say and be exactly: it is not by one one yarns interwoven, woollen yarn knitting together, but with fiber directly method by physics be bonded together, so, during sticking title in you take your clothes, will find, be can not take out one by one the end of a thread.Non-weaving cloth has been broken through traditional weaving principle, and has that technological process is short, speed of production is fast, output height, characteristics such as cost is low, purposes is wide, raw material sources are many.
Its main application is broadly divided into: (1) medical and health use cloth: operating coat, protective garment, sterilization infantees, mouth mask, diaper, sanltary towel etc.; (2) family decoration cloth: wall covering fabric, the tablecloth, sheet, bedcover etc.; (3) with dress cloth: lining, adhesive lining, flocculus, typing cotton, various synthetic leather base fabrics etc.; (4) industrial cloth: filtering material, insulating materials, cement package bags, geotextiles, coating cloth etc.; (5) agricultural fabric: crop protection cloth, seedling cloth, irrigation cloth, insulation curtain etc.; (6) other: space wadding, heat-insulating and noise-insulating material, asphalt felt, tobacco filters, bag bag tea-bag etc.
Nonwoven production mainly is polypropylene fibre (PP), terylene (PET) with fiber, in addition, also has polyamide fibre (PA), viscose rayon, acrylic fibers, polyethylene (HDPE), polyvinyl chloride fibre (PVC).
General nonwoven all is that fiber is made, and the waterproof and dampproof performance of its nonwoven of making is all poor, has limited the development of portioned product, is not well used.
Summary of the invention
At above-mentioned defective, the objective of the invention is to, a kind of permeable membrane is provided, good permeability has excellent waterproof and humidity resistance is strong, can be applied to the surface of nonwoven.
For achieving the above object, technical scheme of the present invention is, a kind of permeable membrane mainly is made up of film and polystyrene resins high molecular polymer, and the composition of described polystyrene resins high molecular polymer is: polystyrene resin; The mixture of one or both in polyethylene, the polyvinyl chloride; The mixture of one or both of chloroform, ethanol.
Preferential, the percetage by weight of described polystyrene resins high molecular polymer is: polystyrene resin 1-20%; The mixture 0.1-5% of one or both in polyethylene, the polyvinyl chloride; The mixture 80-95% of one or both of chloroform, ethanol.
Preferential, described film is a cellulose mixture fat.
Preferential, described film surface is provided with micropore.
Preferential, the aperture of described film is less than 0.5 micron.
Preferential, the brushing of described polystyrene resins high molecular polymer is at the outer surface of film.
Preferential, the aperture of permeable membrane is less than 25 nanometers.
Preferential, the thickness of described permeable membrane is 0.05-0.1mm.
The permeable membrane that the present invention discloses mainly is made up of film and polystyrene resins high molecular polymer, and film surface is provided with micropore, can be applied to the surface of nonwoven, and good permeability has excellent waterproof and humidity resistance.
Description of drawings
Accompanying drawing 1 is the structural representation of permeable membrane in the preferred embodiment of the present invention;
Among the figure, 1 is film, and 2 is the polystyrene resins high molecular polymer.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby protection scope of the present invention is made more explicit defining so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that.
As shown in Figure 1, the structural representation for permeable membrane in the preferred embodiment of the present invention provides a kind of permeable membrane, mainly is made up of film and polystyrene resins high molecular polymer.Film is a cellulose mixture fat, and its film surface is provided with micropore, and the aperture of film is less than 0.5 micron; The composition of polystyrene resins high molecular polymer and percetage by weight are: polystyrene resin 1-20%; The mixture 0.1-5% of one or both in polyethylene, the polyvinyl chloride; The mixture 80-95% of one or both of chloroform, ethanol.
The present invention is uniform brushing one deck polystyrene resins high molecular polymer on film, carry out drying then, form polystyrene resins high molecular polymer permeable membrane, the aperture of prepared permeable membrane is less than 25 nanometers, and the thickness of permeable membrane is 0.05-0.1mm.
The permeable membrane that the present invention discloses mainly is made up of film and polystyrene resins high molecular polymer, and film surface is provided with micropore, can be applied to the surface of nonwoven, and good permeability has excellent waterproof and humidity resistance.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited thereto; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
