Preferably, described fibre bundle is stranded and become by 10-400 root fiber yarn, and this filametntary diameter is 1.5-3 ��m, and now cable line feeder has more excellent tensile strength and toughness.
Flexible adhesives described in this scheme is the one in following tackiness agent: (1) aqueous polyurethane emulsion, (2) polyvinyl butyral cementing agent, (3) Bandaid glue;
Wherein, described polyvinyl butyral cementing agent is made up of the following component according to weight fraction meter: polyvinyl butyral acetal 10-30%, solvent 70-90%, described solvent is any one in alcoholic solvent, ketones solvent and esters solvent.
Preferably, the white carbon black being added with in described flexible adhesives, the addition of described white carbon black is the 3-5% of described flexible adhesives weight.
Preferably, being added with conductive powder in described flexible adhesives, the addition of described conductive powder is the 20-30% of described flexible adhesives weight, and the granularity of described conductive powder is 2-20 ��m. The addition means of described conductive powder is as follows: take flexible adhesives and conductive powder in proportion, is added by conductive powder in flexible adhesives, after high speed dispersor fully disperses, to obtain final product. Add conductive powder so that the line feeder of the present invention has the ability of conduction, it is possible to the core being used in replacement conventional wire cable.
Preferably, described conductive powder is any one in copper powder, aluminium powder, silver powder, graphitized carbon black, Graphite Powder 99, Graphene powder.
Compared to existing technology, the useful effect of the present invention is: compared with existing cable line feeder, gelatinous coating is compound in the outside of fibre bundle, rubstick is filled between fiber yarn, fiber yarn is made to be not easy to scatter, prevent filament surface to produce fluffiness, decrease fiber yarn to the electrical impact of cable; The existence of gelatinous coating can increase wear resistance and the toughness of cable line feeder; Decrease electric wire broken string or copper wire broken string that cable occurs in process of production, jump stock, show money or valuables one carries unintentionally, stranded uneven phenomenon, and the situation of the solder joint void weldering caused on copper stranded conductor surface because being exposed at outside fiber yarn, false weldering can be improved in the follow-up welding processing of cable. Gelatinous coating contains conducting powder not, makes line feeder have the function of conduction.
