Description
Technical field
The present invention relates to membrane material, particularly relate to a kind of surface treatment method of membrane material.
Background technology
Carry out surface-treated membrane material with polyester fiber screen cloth for base material, have quality light, intensity is high, and air-tightness is good, easily welds, fire-retardant, the advantages such as long service life.Therefore, this membrane material is widely used in biogas engineering material, inflatable boat material, Sports floor material, pool liners material, the fields such as New Tent Products.
Then, the membrane material being base material with polyester fiber screen cloth at present, polyester fiber screen cloth lines is easily exposed on film material surface, if only carry out a roller coat surface conditioning agent, the surface-treated layer of such formation can not form the surface layer comparatively completed, have more coating less than region.In the use procedure of film material, these regions be not coated to, will form defect point, and the service life of whole surface-treated layer will be affected.In order to overcome above-mentioned defect, need toward the thick surface conditioning agent of polyester fiber screen cloth substrate surface roller coat one deck, so not only can increase membrane material thickness, membrane material production cost also can be caused high, and product does not have the market competitiveness.
Summary of the invention
The object of this invention is to provide one and make that membrane material cost is low, surface uniform, the surface treatment method of the membrane material that glossiness is high.
For achieving the above object, technical scheme of the present invention is: a kind of surface treatment method of membrane material, and described surface treatment method comprises the following steps:
1) preheating of polyester fiber screen cloth: by the first preheating on the preheat roll of 50-60 DEG C of polyester fiber screen cloth;
2) toward the polyester fiber screen cloth surface roller coating one-time surface finishing agent that preheating is complete, the order number of the thin,tough silk order wheel of a described roller coat is 80-100 order, then dries in the baking oven of 120-130 DEG C;
3) toward the polyester fiber screen cloth surface roller coat secondary surface treatment agent again of drying, the order number of the thin,tough silk order wheel of described secondary roller coat is 120-150 order, then dries in the baking oven of 110-120 DEG C;
4) carry out calendering by through between two minute surface steel riders of the polyester fiber screen cloth feeding calender of twice roller coat, described calendering temperature is 110-130 DEG C, and pressure is 10-30kg; Obtain the polyester fiber screen cloth membrane material that surface treatment is good;
5) polyester fiber screen cloth membrane material good for surface treatment is cooled to room temperature;
6) to the membrane material rolling cooled.
Adopt above surface treatment method, first a roller coat is carried out to polyester fiber screen cloth, one-time surface finishing agent is tentatively filled the mesh in polyester fiber screen cloth; And then secondary roller coat is carried out to polyester fiber screen cloth, on the basis that the mesh in polyester fiber screen cloth is tentatively filled, secondary roller coat easily make surface-treated layer the mesh position of polyester fiber screen cloth and other positions of polyester fiber screen cloth smooth; Need not form thick surface-treated layer on polyester fiber screen cloth surface can make surface-treated layer end face smooth, and the membrane material thickness obtained is thin, and cost is low.
Meanwhile, the thin,tough silk order wheel order number of a roller coat is little, so mesh is rare, easily one-time surface finishing agent is packed into the mesh position of polyester fiber screen cloth; The thin,tough silk order wheel order number of secondary roller coat is large, and mesh is close, makes secondary surface treatment agent form fine and close, even curface processing layer on polyester fiber screen cloth surface.
The calendering process of step 4) make the end face of the membrane material surface-treated layer obtained evenly, fine and close, glossiness is high; Polyester fiber screen cloth and surface-treated layer are bonded more tight, surface-treated layer plate defects point is few, and membrane material overall performance improves.
Thin,tough silk order wheel in described step 2 is different with the thin,tough silk order wheel surface pattern in step 3, thus roller coat is carried out in the place making roller coat different to polyester fiber screen cloth respectively with secondary roller coat, makes the surface-treated layer end face of twice roller coat formation more even.
Described step 2) in dry 30-40s in an oven through the polyester fiber screen cloth of a roller coat, the flash baking of a roller coat, be convenient to enter secondary roller coat program fast, be conducive to enhancing productivity.
Polyester fiber screen cloth through secondary roller coat in described step 3) dries 100-150s in an oven.
Described step 2) in the component of one-time surface finishing agent and parts by weight be:
Surface conditioning agent base-material 100 parts;
Diluent 5-10 part;
Described surface conditioning agent base-material is the one in polymethyl methacrylate or polyvinylidene fluoride, and diluent is one or more the mixing in toluene, butanone or dimethyl formamide.
Component and the parts by weight thereof of the secondary surface treatment agent in described step 3) are:
Surface conditioning agent base-material 100 parts;
Diluent 10-20 part;
Described surface conditioning agent base-material is the one in polymethyl methacrylate or polyvinylidene fluoride, and diluent is one or more the mixing in toluene, butanone or dimethyl formamide.
Amount of diluent in described one-time surface finishing agent is low, and solid content is high, tentatively fills the mesh in polyester fiber screen cloth when being convenient to carry out a roller coat; Amount of diluent in secondary surface treatment agent is high, and solid content is low, forms uniform surface-treated layer when being convenient to carry out secondary roller coat on polyester fiber screen cloth.
Also be provided with storing step between described step 5) and step 6), when change of lap, between step 5) and step 6), be provided with storage rack, the membrane material first rolling storing on storage rack of step 5) cooling.Like this when needs change of lap, do not need to shut down, in order to avoid cause wastage of material.
After the rolling of described step 6), be also provided with bundling operation, adopt single shaft crimping device, when needs directly become little coil packing, directly carry out bundling, avoid secondary bundling, cause the destruction on membrane material surface.
The surface treatment method of membrane material of the present invention, adopts secondary roller coat to obtain surface-treated layer, makes that the surface-treated layer end face of formation is more even, smooth, fine and close, glossiness is high.The surface treatment method of membrane material of the present invention makes membrane material thickness be effectively controlled, and production cost is low, and the market competitiveness is strong.
