Abstract

A kind of silica gel cable cover(ing) of high intensity, is related to technical field of electric wires and cables, and the preparation method of the cable cover(ing) is：A floor height strength net is added in silica gel sheath layer internal layer or silica gel sheath layer with the mode of physics, while silica gel and web is closely integrated into an entirety by pressurizeing and vulcanizing layer of silica gel.The high strength fibre stratum reticulare is inside the layer of silica gel；Or high strength fibre stratum reticulare is wrapped on cable core, layer of silica gel is wrapped in outside high strength fibre net.The purpose of this utility model is to reduce silica gel sheath elongation, protective effect of the enhancing silica gel sheath to inner cable, the service life of extension silica gel cable.The beneficial effects of the utility model are：The technical program can effectively reduce silica gel sheath elongation, improve the tensile strength of silica gel, effectively protective effect of the enhancing silica gel sheath to inner cable, the service life of extension silica gel cable.The utility model adapts to various medical silica gel cables, characteristic and advantage without influenceing silica gel.

Description

A kind of silica gel cable cover(ing) of high intensity

Technical field

The utility model belongs to technical field of electric wires and cables, more particularly to a kind of silica gel cable cover(ing) of high intensity.

Background technology

The construction of cable can generally be divided into conductor, insulating barrier, screen layer and the part of restrictive coating four composition.Because electric wire It is required that insulating materials has excellent electrical insulation capability, its protective capacities to the external world can not be often taken into account, so for the external world The resistance of various external force, corrosion-resistant, anti-aging and fire protecting performance resist power often wretched insufficiency, and restrictive coating is exactly to make up The key point of problems.Therefore require that cable cover(ing) there should be the good characteristic such as insulation, corrosion-resistant, non-aging.Conventional Cable sheath material has fiber, General Purpose Rubber, plastics and nylon etc..

Compared with other cable sheath materials, silicon rubber has good high temperature resistant, low temperature resistant, electrical insulating property, oxytolerant Ageing resistance, chemical stability etc., and soft texture.Therefore the cable in surgical device with human contact all uses silicon Plastic boot, it is in height bending, height waves, oxirane Aseptic sterilisation, high-temperature vapour sterilize, FDA ratifies, is given birth to by ISO10993 It is more with the obvious advantage than other resin materials in physical property test atmosphere.But silica gel material easily extends, elongation >=700%, and cable Inner structure elongation is little, for a long time using the particularly effect of pullling, silica gel sheath can be made to protect cable inner structure inadequate, made Reduced into electric wire service life.

Utility model content

The utility model purpose is the silica gel cable cover(ing) for providing a kind of high intensity, can effectively reduce silica gel sheath elongation Rate, the tensile strength of silica gel is improved, protective effect of the enhancing silica gel sheath to inner cable, effectively extend silica gel cable uses the longevity Life.

The utility model is to realize that the purpose adopts the technical scheme that：A kind of silica gel cable protection of high intensity is provided Set, the silica gel cable cover(ing) include silica gel sheath layer and fiber web layer, and plastic boot layer and fiber web layer are closely integrated into one It is overall.The layer of silica gel and the high strength fibre net are that an entirety is closely integrated into a manner of physics.It is described high-strength Fiber web layer is spent inside the layer of silica gel.Or the high strength fibre stratum reticulare is wrapped on the cable inside, the silica gel Layer is wrapped in outside the high strength fibre net.The high strength fibre net can be KEVLAR filaments, polytetrafluoroethylene (PTFE) seam Thread line and heat-resisting aramid fiber etc..

The beneficial effects of the utility model are：The technical program can effectively reduce silica gel sheath elongation, improve silica gel Tensile strength, effectively protective effect of the enhancing silica gel sheath to inner cable, the service life of extension silica gel cable.The utility model Scheme adapts to various medical silica gel cables, characteristic and advantage without influenceing silica gel.

Embodiment

In order that technical problem, technical scheme and beneficial effect that the utility model solves are more clearly understood, below In conjunction with the embodiments, the utility model is further elaborated.It should be appreciated that it is as described below be only it is of the present utility model compared with Good embodiment, not to limit the utility model, therefore, as long as with the utility model specification and drawings content institute All any modification, equivalent and improvement of work etc., should be included within the scope of protection of the utility model.

A kind of silica gel cable cover(ing) of high intensity of the utility model, it is to add a floor height strength in silica gel sheath Net, makes web and silica gel integrator, and specific implementation has two kinds of means：

Embodiment 1 with oil-free braider 3 inside the cable on equably weave a floor height strength, described The fiber web layer 2 is formed on 3 inside cable, gel coated is made on the layer of high strength fiber by pressure, coatedly together When remove fiber in moisture and volatile materials, by vulcanizing silica gel, silica gel and web are bonded into an entirety.

Embodiment 23 first inside the cable on coat the layer of silica gel 1 of a half thickness, then in the silicon The high strength fibre stratum reticulare 2 is equably woven on plastic boot layer 1, by pressure by the silica gel sheath layer of another half thickness 1 is coated on the high strength fibre net 2, coatedly moisture and volatile materials in web is removed simultaneously, by making silica gel Vulcanization, an entirety is bonded into by silica gel and web.

It should be appreciated that in description of the present utility model, the orientation or position relationship of the instruction such as term "left", "right" Based on orientation shown in the drawings or position relationship, to be for only for ease of description the utility model, rather than require that this practicality is new Type must be with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
