Abstract
The invention relates to a formula of polytetrafluoroethylene glass fiber breathable varnished cloth. The polytetrafluoroethylene glass fiber breathable varnished cloth is characterized by being prepared from the following components in percentage by weight: 30-40% of polytetrafluoroethylene, 0.5-0.8% of a surfactant and the balance of deionized water and alkali-free glass cloth, wherein the warp density and the weft density are respectively 200/10cm (+/-10%), the thickness is 0.04-0.06mm and the breadth is 900-1000mm. The polytetrafluoroethylene glass fiber breathable varnished cloth provided by the invention has the beneficial effects that by customizing the glass fiber base cloth, the formula and a production process are improved, so that polytetrafluoroethylene emulsion uniformly coats and steeps the alkali-free glass cloth, and the formula is reasonable; the prepared polytetrafluoroethylene glass fiber breathable varnished cloth is free of bubbles on the surface, uniform in glue content, good in air permeability and low in production cost, has the high-temperature-resisting and high-strength performances of a glass fiber fabric, and also has a series of excellent performances such as insulation and adherence resistance of polytetrafluoroethylene.
Description
Technical field
The invention belongs to technical field of polymer composite materials, be specifically related to a kind of polytetrafluoroethylglass glass fiber and breathe freely varnished cloth and formula.
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 that in prior art, (1) polytetrafluoroethylmicroporous microporous membrane and glass fabric compound obtain fill a prescription complicated, production cost is 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:
A kind of polytetrafluoroethylglass glass fiber is breathed freely varnished cloth formula, and each composition quality is than as follows: polytetrafluoroethylene content is 30 ~ 40%; Surfactant 0.5 ~ 0. 8%, surplus are deionized water and Ji Bu.
The breathe freely base cloth warp-wise of varnished cloth and latitudinal density of polytetrafluoroethylglass glass fiber is: 200/10 centimetres (± 10%), thickness: 0.04 millimeter ~ 0.06 millimeter, fabric width: the alkali-free glass cloth of 900 ~ 1000 millimeters.
Preferably, each composition quality is than as follows: polytetrafluoroethylene content is 35%; Surfactant 0.65%, surplus are deionized water and warp-wise and latitudinal density: 200/10 centimetres, thickness: 0.05 millimeter, fabric width: the alkali-free glass cloth of 950 millimeters.
Polytetrafluoroethylglass glass fiber is breathed freely varnished cloth thickness: 0.05 millimeter ~ 0.07 millimeter, fabric width: 900 ~ 1000 millimeters.
Polytetrafluoroethylglass glass fiber is breathed freely the air penetrability of varnished cloth: be greater than 500mm/s when being greater than 200mm/s, 200pa during 50Pa.
Beneficial effect of the present invention: by customizing fiberglass-based cloth, improve formula and production technology, ptfe emulsion is applied equably, be immersed on alkali-free glass cloth, fill a prescription more reasonable, make polytetrafluoroethylglass glass fiber breathe freely varnished cloth surface bubble-free, gel content is even, permeability is good, production cost is low, it had both had the high temperature resistant of glass fabric, high-intensity performance, there is again the insulation that polytetrafluoroethylene (PTFE) is excellent, a series of performance such as antiseized, be widely used in high temperature resistant, ventilative, antiseized, vacuumize, the field such as negative pressure and the demoulding of elimination, it is a kind of high-performance, multiduty polymer composite.
Detailed description of the invention
