Abstract
The invention relates to a production method for polyethylene (PE) textured longitudinal wrapped belt of a railway internal screening digital signal cable, and relates to the technical field of cable production, in particular to a production method for a longitudinal wrapped belt. The production method comprises the following steps of: mixing low-density polyethylene, wire drawing polypropylene, ethylene vinyl acetate (EVA) resin and a wear-resisting and temperature-resistant agent uniformly, putting the mixture into a sheet extruding machine, heating, extruding, sizing by water cooling, drawing, embossing, rolling, splitting and packaging. The method is simple, reasonable and easy to operate, and products are high in stability; and the PE textured lining longitudinal wrapped belt of the digital signal cable plays a certain role in ensuring that the inside of the signal cable is insulated and is free from damage and retarding the attenuation of signal transmission.
Description
Technical field
The present invention relates to the cable production technical field, particularly the production method of vertical band.
Background technology
Constantly open-minded along with high-speed railway, interior screen closes digital signal cable and is widely used, and in order to improve the traffic safety of high ferro, the quality that improves constantly cable is the corporation responsibility of cable manufacturing enterprise and material produce producer.
Summary of the invention
The object of the invention is to provide the production method that a kind of flexibility is good, the interior screen of the railway of good insulating closes the vertical band of digital signal cable PE reticulate pattern.
The present invention with 65～76 weight part new LDPE (film grade)s, 10～16 weight part wire drawing grade polypropylenes, 8～15 parts of EVA resins and 2～5 weight part wear-resistant temperature-resistant agent uniform mixing after, put into the sheet extrusion machine and heat and extrude, form through water-cooled shaping, traction, embossing, rolling, itemize, packing.
Technology of the present invention simply, rationally is easy to production operation, and product stability is good, as the vertical bag of digital signal cable PE reticulate pattern liner band, plays a role for ensureing to insulate injury-free in the signal cable and slow down the signal transmission attenuation.
Its principal feature shows as:
1, because the PE reticulate pattern strips has good softness, under the effect of mould, can closely wrap during vertical the bag and be attached to cable core external insulation surface, make it when compacting copper strips wrinkle, can not damage the thin inner insulating layer of cable core;
2, because the vertical bag of PE reticulate pattern band has adopted the embossing of special cellular decorative pattern, form even cellular sags and crests on the band surface, make it to form air bubble clump and further increased insulating property, the decay in the blocking signal transmission at copper strips bellows inwall;
3, carried out the embossing processing because of the band surface, make it to compare with the level and smooth band of more not embossing, also save simultaneously the same 0.2 ± 0.02mmx25 of being of this band of the nearly 20%(of material cost specification ± 0.5mm having improved electrical insulation capability, the thickness of chenille ribbon before embossing is 0.15-0.16mm, reaches primary standard after the decorative pattern compacting and requires).
Embodiment
Production technique: with the PE(new LDPE (film grade) of 65～76kg), the PP(wire drawing grade polypropylene of 10～16kg), the wear-resistant temperature-resistant agent of the EVA resin of 8～15kg and 2～5kg is after homogenizer evenly stirs, put into the sheet extrusion machine, extrude through heating, again through water-cooled shaping, traction, form through the embossing of reticulate pattern mould, rolling, itemize, packing.
Claims (1)
1. screen closes the production method that digital signal cable PE reticulate pattern is indulged band in the railway, it is characterized in that behind 65～76 weight part new LDPE (film grade)s, 10～16 weight part wire drawing grade polypropylenes, 8～15 parts of EVA resins and 2～5 weight part wear-resistant temperature-resistant agent uniform mixing, put into the sheet extrusion machine and heat and extrude, form through water-cooled shaping, traction, embossing, rolling, itemize, packing.
