Background technology
Polytetrafluoroethylmaterial material has performances such as excellent chemically-resistant, heatproof, insulation, sticking and self-lubricating, has great use value in fields such as medicine, industry and environmental protection.In recent years, the application of high-performance poly tetrafluoroethene biaxial stretching film and exploitation have been obtained paying attention to widely, the process equipment that adapts is with it also developed fast.Chinese patent disclose a kind of expanding microporous poly tetrafluoroethylene the preparation method (publication number: CN 101007242A), it comprises: batch mixing, striking adobe, extrude, vertical draw, the horizontal operation of drawing, in extruding operation, adopt the die head of flat pattern mouth mould; Extruding and vertical drawing increased calendering operation together between the operation, concrete steps are as follows: (1) batch mixing: polyflon and the auxiliary agent raw material chosen are fully stirred; (2) striking adobe: will be through the even mixed raw material of last process, under 40 ℃ of temperature, fully soak into after inserting baking oven, make the column base substrate by pre-shaping device; (3) extrude: adopt the die head flat-die of pancake mouth mould to extrude, extrude load pressure control at 3-4Mpa, extruded velocity is 1-5m/min, makes the column base substrate be transformed into the flat belt-like sheet material; (4) calendering: be that hauling speed is 1-5m/min under the pressure roller effect of 20-30Kg/cm at linear pressure with the flat belt-like sheet material of extruding, be made into the broadband that thickness is 150-500 μ m; (5) vertical drawing: with the broadband that last process makes, under 100 ℃-250 ℃ temperature, vertical drawing is prepared into the vertical base band of drawing; (6) horizontal drawing: the vertical base band of drawing with last process makes at 50 ℃ of-350 ℃ of following cross directional stretch, at 340 ℃ of-370 ℃ of curing moldings, makes the ePTFE film.But this method is more inhomogeneous to the stretching of film band, and unadjustable stretch ratio, and the film size that making stretches comes out is unstable, and rolling is more irregular.
The utility model content
The utility model provides a kind of longitudinal tensile fixture for the PTFE film preparation, it mainly is to solve existing in prior technology more inhomogeneous to the stretching of film band, and unadjustable stretch ratio, the film size that making stretches comes out is unstable, the technical problem of the more irregular grade of rolling.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of PTFE multifunctional membrane swift short distance stepless speed regulation longitudinal tensile fixture of the present utility model, comprise baking oven, the film band import department of described baking oven one end is provided with unwinding device, be provided with degreasing district and drawing zone in the baking oven, be provided with a plurality of cylinders that deoil in the degreasing district, be provided with the tensile roller of a plurality of S of being arranged in types in the drawing zone, the film band exit of the baking oven other end is provided with chill roll, the top of baking oven is provided with exhaust outlet, and the bottom of baking oven is provided with heating plate.This unwinding device is that the PTFE roll coil of strip that do not stretch is pressed against above the stainless steel drum to rotate with cylinder and unreels.Heating plate under the degreasing district mainly contains and 5-7 the cylinder that deoils formed, and all cylinder linear velocities of its degreasing district are the same.At stretch section baking oven top exhaust outlet is arranged, prevent oil accumulation in baking oven, produce blast.Be wrapped on the chilling roll through the basement membrane behind the drawing by high temperature and cool off, its centre of the drum is through-flow moving cold running water.By adding the chilling roll cooling, in the time of can avoiding traditional stretcher rolling stretched film shrink big, the irregular shortcoming of rolling.The film band that stretching is finished can be around twisting on the rolling cylinder, and the rolling cylinder is driven by winding motor independently, between motor and wrap-up magnetic powder cluth is housed, and the tension force size of controlled controlling rolling reaches the purpose of even rolling.Whole wrap-up can be by the centralising device rolling of aliging automatically.This longitudinal tensile fixture its to unreel speed be 0-4m/min, total draw ratio 4-20 doubly, rolling speed 5-60m/min
As preferably, described tensile roller includes first tensile roller, second tensile roller, the 3rd tensile roller, the 4th tensile roller, the 5th tensile roller, the 6th tensile roller, the 7th tensile roller, wherein to unreel speed identical with the linear velocity of the cylinder that deoils for first, second tensile roller, by a frequency modulator speed regulating control; Three, the 4th, the 5th tensile roller is respectively by separately frequency modulator speed regulating control; Six, the 7th tensile roller linear velocity is identical, by independent frequency modulator control speed governing.Can change the drawing process condition fast by 5 frequency modulators.
As preferably, the inwall of described baking oven is provided with heating plate, and the effect of deoiling like this and stretching is better.
As preferably, described tensile roller is the swift of diameter 200-300mm, and the gap between the adjacent roller is 15-25mm.
Therefore, the utility model adopts five to roll four sections stretchings, and the stretch section cylinder is the above swift of diameter 200-300mm, and the gap between the adjacent roller is 15-25mm, tensile roller guarantees the quick all performance-adjustables of even stretch ratio that stretch all by independently frequency control motor control.Can make the film size that stretches keep stable by chilling roll, rolling is neat, and is simple and reasonable for structure.
