Abstract
The utility model relates to a Polytetrafluoroethylene (PTFE) and glass fiber butt fusion compound cloth of high strength PTFE butt fusion that forms, its leading features have the compound butt fusion layer of one deck outside the PTFE surface layer, and glass fiber inserts in the PTFE film like fish scale in the compound butt fusion layer. This product has overcome the defect in the technology manufacturing that PTFE non-adhesiveness brought, and PTFE expend with heat and contract with cold big, shortcoming such as yielding to have advantages such as simple process, high productivity ratio, the utility model discloses can provide the lining and the various anti-sticking cloth of pipeline, pipe fitting, tower, equipment.
Description
The utility model relates to the high-strength polytetrafluoroethyl-ne welding Compound Fabric product that a kind of glass fibre and the effective welding of polytetrafluoroethylene (PTFE) form.
Known PTFE and glass fibre Compound Fabric, its structure and manufacture method utilize the PTFE dispersion liquid as cementing medium, as Chinese 90101133.9 products.Help PFA or other fluoropolymer polymer as cementing medium, as the product of clear 57-5180 of Japan and clear 60-115440.Because PTFE itself has not viscosity, thus poor bonding strength, complex process, result of use is undesirable.
The purpose of this utility model provides a kind of even more ideal high strength PTFE welding Compound Fabric product, and it is remarkable in conjunction with effect, the mechanical strength height, and it is little to expand with heat and contract with cold, indeformable, and technology is simple, the productivity ratio height, cost is low, the complete welding of PTFE and glass fibre.
The technical solution of the utility model is that a, multilayer PTFE film twine on the cylindrical mould axle or superpose on flat board, form certain thickness PTFE superficial layer; Or directly utilize certain thickness PTFE plate as the PTFE superficial layer; The outside stack width of b, PTFE superficial layer equates, one deck PTFE film band that thickness is close and one deck fabric band, PTFE film band is in the paving, lining, the fabric band is the paving outside, and simultaneously, in the same way, Duplication with 50% is twined or is superimposed upon on the PTFE superficial layer, and this forms compound welding layer; C, tie up the technology glass fiber tape, tying up tension force is 10～100Kgf, with its sinter molding, insulation, cooling, pulls down the technology glass fiber tape; Or directly on special-purpose press, exert pressure sinter molding, insulation, cooling; D, on compound welding layer, coating adhesive repaves one or more layers fabric, the heating cure under pressure forms glass fiber reinforced layer.G, on mould, cut off or directly take out mould with cutter; Or directly on flat board, high strength PTFE welding Compound Fabric.
Key of the present utility model is that various PTFE dispersion liquids of eliminating or fluoropolymer polymer are made cementing medium, directly set up compound welding layer, when wide uniform thickness, paving, lining PTFE film band, outer paving fabric band with simultaneously in the same way, when 50% Duplication is twined stack, the paving is the PTFE material entirely under the compound welding layer, it and PTFE inner liner are same material, are fused into the one that does not have the slit fully, thereby have overcome the defective of making on the PTFE technology that viscosity is not brought.The paving is fabric web material entirely on the compound welding layer.Advantages such as event has the mechanical strength height, and it is little to expand with heat and contract with cold, indeformable.This layer of fabric inserts in the PTFE film as fish scale, so the intensity height, anti-stripping property is good.Need not brush PTFE dispersion liquid and various fluoropolymer polymer, so it is simple to have technology, the advantage that cost is low, productivity ratio is high.
Be described further below in conjunction with accompanying drawing.
(1) is the PTFE superficial layer among Fig. 1.The PTFE film thickness can be 0.05～0.8 millimeter, preferably gets and standard fibers fabric thickness value, and as 0.08,0.1,0.17 millimeter; 5～200 millimeters of width are preferably got and standard fibers fabric width value, as 25,30,35 millimeters.(2) be compound welding layer, PTFE thin-film width, thickness are with the same in (1) in this layer, and the fabric band can be got high-temperature fibre bands such as glass fiber tape or asbestos yarn.(3) be glass fiber reinforced layer, fabric wherein can be the high cloth of mechanical strength such as glass fabric, and binding agent wherein can select epoxy resin, phenolic aldehyde-butyronitrile, the binding agent of good, the anti-200 ℃ of temperature of adhesive properties such as epoxy-nylon.The paving is a glass fibre on the PTFE welding Compound Fabric, utilize the good caking property of glass fibre, it is bonded on the metal, can be made into the bridge pad of low friction, machine tool guideway, the motor buffer zone of electric insulation, various seals, the various anti-sticky cloth of viscosity not, the topped material in roof can be used as the lining of corrosion resistant chemical pipeline, pipe fitting, tower, equipment.
Embodiment 1:
Fig. 2 is the lining of Dg1500 millimeter PTFE welding Compound Fabric as chemical industry equipment, and thick 1.5～2.0 millimeters of the compound welding cloth of PTFE is coated binding agent outside it, spreads the glass fabric of state's vaginal orifice 900 millimeters, tightly serves as a contrast among steel shell.Improve 5 times or more than conventional lining products its service life.
Embodiment 2:
The PTFE film of 30 millimeters of thick 0.1 mm wides is wrapped on the mould, the paving is a PTFE film band in twining thereon again, outer paving is a glass fiber tape, thickness is 0.1 millimeter, 30 millimeters of width, twine with 50% Duplication simultaneously, tie up the technology glass fiber tape more outside, through sintering, insulation, cooling, pull down the technology band, repave fabric and binding agent, be heating and curing, the demoulding, get PTFE welding Compound Fabric, it is bonded on rubber and the bridge pad slide block, has the low and good advantage of caoutchouc elasticity of PTFE coefficient of friction, can bear bridge fulcrum reaction power and corner.
Embodiment 3:
The performance test of PTFE welding Compound Fabric: (1) is detected through the high-frequency spark of 12KV, and there is not micropore in the no-spark punch-through.(2) tensile strength, PTFE welding Compound Fabric is made standard specimen, and to record tensile strength mean value on stretching-machine be 350kgf/cm
2(3) survey friction co-efficient value: PTFE superficial layer friction co-efficient value is 0.04.
