Background technology
Glass fabric does not have that intensity is high, dimensionally stable, high temperature resistant, good corrosion resistance and filter efficiency advantages of higher, but glass fibre also has obvious shortcoming, i.e. crisp, the not folding of property, wear-resisting, easily weares and teares, fractures, affect service life.
Polytetrafluoroethylmicroporous microporous membrane adopts biaxial tension technology to produce, there is unique microcellular structure, Air permenbility is large, resistance is low, high particulate trap rate, temperature tolerance are good, anti-strong acid, alkali, organic solvent and oxidant, the features such as ageing-resistant and sticky, noninflammability and nontoxic, biocompatibility, use after the application technology of current microporous teflon membran mainly carries out compound with fabric or supatex fabric, its complex process, cost is high.
To improving the performances such as the folding of glass fabric, wear-resisting and hydrophobicity after coated glass fiber polytetrafluoroethylene (PTFE), increase the service life most important.Glass fabric is after dipping ptfe emulsion; through super-dry, cure, the operation such as sintering; maceration extract is dried and makes it in fiber surface film forming; reach protection fiber; make it from chemical attack; and improve outside the properties such as its folding, wear-resisting and hydrophobicity, also must possess superior permeability.
The breathable cloth complex process that in prior art, (1) polytetrafluoroethylmicroporous microporous membrane and glass fabric compound obtain, production cost are high, unstable properties; (2) method of the direct coated glass fiber cloth of ptfe emulsion, because emulsion formulations is unreasonable, easily produce bubble, gel content is higher, and permeability is poor, is difficult to the technical requirement reaching regulation.
Summary of the invention
For solving the problems of the technologies described above, as follows for the technical scheme of the employing of invention:
Prepare polytetrafluoroethylglass glass fiber to breathe freely the technique of varnished cloth, comprise the following steps:
(1) preliminary treatment of glass cloth: the wax of 2.5% must be added owing to preventing when ORGANDY is woven into glass cloth fractureing as lubricant, first should eliminate before impregnation, otherwise not easily be infiltrated by PTFE emulsion, and spread can be uneven.Pretreated method dries with the speed of 10 ~ 15 m/min to burn under the high temperature of 450 DEG C, sintering zone, both can remove wax, and also can remove glass hair in small, broken bits;
(2) impregnated glass colth: pretreated for step (1) ORGANDY is immersed four dipping tanks containing polytetrafluoroethylene (PTFE), the polytetrafluoroethylene content of dipping tank respectively: 30%, 30%, 40%, 40%, soak time is 2-6m/min;
(3) dry, the glass cloth soaked in step (2) is carried out drying, and baking temperature is 80-90 DEG C, removing moisture, makes grey cloth micro-dry;
(4) cure, cured by dried glass cloth in step (3), stoving temperature is 280-290 DEG C, and the surfactant in removing ptfe emulsion and moisture, through repeatedly flooding the grey cloth obtaining larger coating;
(5) sinter, baked grey cloth in step (4) is sintered through sintering zone, sintering temperature is 380-400 DEG C, sintering velocity is identical with impregnating speed, behind sintering zone, polytetrafluoroethylene (PTFE) components fuse, interface disappears and welding is surperficial at glass fiber yarn, become the Compound Fabric having good bonding power with ORGANDY, the surfactant in maceration extract all decomposes at a sintering temperature and does not remain in goods;
(6) cool, sintered part can be taken out in high temperature furnace after terminating and cool, improve Wear Resistance.
Preferably, in step (2), preferred dip time is 2.5m/min.
Preferably, in step (3), preferred baking temperature is 85 DEG C.
Preferably, in step (4), preferred stoving temperature is 285 DEG C.
Preferably, in step (5), preferred sintering temperature is 388 DEG C.
Beneficial effect of the present invention: by being applied equably by ptfe emulsion, being immersed on alkali-free glass cloth, makes glass fabric through ptfe emulsion dipping, drying, bakes and banks up with earth, sinters one-shot forming, simplify preparation technology, saved energy consumption.Breathe freely varnished cloth surface bubble-free, gel content of the polytetrafluoroethylglass glass fiber produced is even, permeability is good, production cost is low, it had both had high temperature resistant, the high-intensity performance of glass fabric, there is again the excellent insulation of polytetrafluoroethylene (PTFE), a series of performance such as antiseized, be widely used in high temperature resistant, ventilative, antiseized, vacuumize, eliminate the field such as negative pressure and the demoulding, be a kind of high-performance, multiduty polymer composite.
