Description
Technical field
The present invention relates to a kind of polytetrafluoroethylene (PTFE) seal strip, it especially is suitable for the installation of the pneumatic braking system, natural gas in home pipeline, resident living water pipeline etc. of hydraulic efficiency system, train and the heavy load truck of engineering machinery.The invention still further relates to a kind of storage belting, be used for holding therein seal strip, raw material band for example, and can control the length of extracting seal strip out easily.
Background technology
Widely used material is anaerobic type seal gum, teflon seal tape (raw material band) and lead oil flax silk on the pipeline thread seal at present.
The stopping property of anaerobic glue and locking intensity can meet the demands, and still being assembled to come into operation from gluing needs to wait for the time of several hrs, can not satisfy the requirement of productive temp.And anaerobic glue contains methyl acrylic ester, and certain toxicity and pungency are arranged.
The using method of lead oil flax silk is to be coated with one deck lead oil on outside screw, twine flax silk again, this sealing material is two portions systems, use cumbersome, and because flax silk can be supported microorganism growth, do not satisfy the standard of materials contact with tap water, so make its application be subjected to a great extent restriction.
By contrast, advantages such as esy to use, safe and reliable, no setting time that teflon seal tape has, easy storage, thereby obtained widespread use.But existing teflon seal tape exists that tensile strength is low, easy fracture of wire when assembling back is adjusted, to shortcomings such as the locking moment of pipeline are low.
In order to improve the defective of this two portions of lead oil flax silk system, relate to a kind of sealing material and divider thereof among the patent 98804286.X, directly apply to the threaded portion of pipe by divider through the multifilament of non-curing paste composition coating.Wherein non-curing paste composition contains oil and filler, and this oil is mainly linseed oil, silicone oil and mineral oil; Multifilament is polymeric amide or polypropylene.
Though this method is simple to operation, owing to contain a large amount of oil and filler, thereby correspondingly brought some defectives.Specifically, wherein, linseed oil is a kind of unsaturated oil, and this makes it easily oxidized, and the shelf lives is shorter, though can make problem reduce to minimum by packing, have increased the cost of the finished product simultaneously again.In addition, because oil spills, therefore in tap water, leave the remaining taste of linseed oil from the joint sealing composition.Mineral oil has another name called Liquid Paraffin, paraffin oil, whiteruss, is in the crude oil extractive process, fractionate out useful light materials after, oil forms through refinement again at the bottom of the residual tower.Its proterties is that colourless translucent oily does not have (or being close to nothing) fluorescence liquid.Odorless, tasteless during cooling has more weak petroleum odour during heating.Water insoluble and ethanol, has perviousness, the property of softening and plasticity-at easily emulsification, does not absorb in the intestines.Because mineral oil is not absorbed or digests at human intestinal, can hinder the absorption of moisture simultaneously, medically it is used treatment the elderly or children's constipation as emollient laxative.A large amount of absorptions can cause just soft, diarrhoea; Long-term absorption can cause digestive disorder, influences the absorption of fat-soluble A, D, K and calcium, phosphorus etc.Silicone oil, especially methyl-silicone oil can not contact stronger acid, alkali, even acid, the alkali of trace under the situation of being heated, also can cause silicon oil gelation.And according to Chinese food habits, prefer to fry in shallow oil, explode, stir-fry and eat product, the silicone oil from sealing material infiltration water inlet will threaten to safe diet like this.So this sealing material is used for the installation of resident living water pipeline, and it is healthy that life-time service can endanger the resident.
In addition, the sealing material that relates among the patent 98804286.X is with traditional method sealing compositions to be coated in multifilament, and then is wound on the littler bobbin and uses for the operator.So not only complex manufacturing process, and sealing compositions just is coated on the surface of multifilament, is easy to split away off enter pipe interior, polluted-water or other medium.
At the shortcoming of polytetrafluoroethylraw raw material band, scholars have also done a large amount of research.Find that by inquiry a lot of patents have all related to the modification to tetrafluoroethylene, as improving its performance by synthon, the synthesis technique that improves tetrafluoroethylene to current material; Perhaps fiberfill fibers, inorganic powder and organic polymer filler carry out modification in PTFE; Perhaps carry out PTFE and other material such as rubber plate, layer of fibers compound.But above-mentioned method of modifying almost is not used in the modification to polytetrafluoroethylraw raw material band base (base band), and these modifications relate generally to is improvement to the wear resistance of polytetrafluoroethylmaterial material, and seldom relates to the improvement to its tensile strength.
Chinese patent 02217494.X has related to a kind of wired teflon seal tape, and this seal strip is divided into three layers, and upper and lower layer is the tetrafluoroethylene tape base, and the middle layer is a layer of fibers, and tetrafluoroethylene tape base and layer of fibers are packed together to one.Wherein fiber is a kind of in hemp silk and the regenerated fiber, and diameter is 0.02mm-0.07mm.This patent does not relate to the tensile strength that this method can improve teflin tape yet, and teflin tape is the broadband of wide 10mm-25mm, the broadband is not easy to workman's operation, in application process, pass many screw threads, destroyed easily during threaded together, breakage takes place and split away off the pollution pipeline internal medium.
Chinese patent 98804286.X relates to a kind of divider that is used to pack its sealing material, and by this divider, multifilament can be extracted out from storing unit, uses the blade cuts that is installed on the dispenser cover to be used for the sealing of gas thread.But the multifilament length of extracting out is wayward, causes waste easily.And if the multifilament long-term exposure applies superincumbent sealing compositions and can take place rotten as parching (volatilization) or oxidation in air.
