Abstract
The invention provides a cable filler composition, particularly a cable filler composition which has the advantages of high PTC (positive temperature coefficient) strength, favorable temperature control property, small self-limit temperature fluctuation, high strength, high tension rate and favorable flame retardancy. The cable filler composition is prepared from modified PVC (polyvinyl chloride), a PVC stabilizer, a filler, powder nitrile-butadiene rubber, kieselguhr, BaTiO3, SrTiO3, Y2O3, Nb2O5, MnO2, Y2O3 and Tu2O3.
Description
Technical field
The present invention relates to a kind of cable filler, relate in particular to a kind of temperature automatically controlled cable filler compsn with good physicochemical characteristic.
Background technology
So-called ptc characteristics, i.e. positive temperature coefficient of resistance characteristic, along with temperature rises, heating element resistance increases, thus the outward current size is regulated in restriction or cut off electric current automatically, and temperature is kept constant.The heating cables of being processed by the resin with this specific character is referred to as temperature automatically controlled type heating cables.
Present automatic temperature control cable stopping composition compsn is a matrix with crystalline macromolecular compound generally; Conducting particless such as a large amount of blending carbon blacks, graphite and metal powder; The temperature automatically controlled type heating cables of processing by this stopping composition compsn; In successive energising or the circulation of break-make electricity, because resistance raises, surface temperature descends very big.This is that the difference of polarity and thermal expansion between macromolecule matrix and conduction current carrier causes carbon black particle displacement and reunion on the one hand, has produced to be separated and to cause; Be that the adaptation difference causes between heating element and electrode on the other hand.It is low that carbon black, the graphite of while in automatic temperature control cable stopping composition compsn has PTC intensity, the shortcoming of temperature-control performance difference; Chinese patent CN 102108169 discloses a kind of automatic temperature control cable material stopping composition composition and method of making the same, and its main ingredient and weight percent are: modified PVC 85～90, PVC stablizer 5～10, filler 1～5, BaTiO

Summary of the invention
To above-mentioned shortcoming, the object of the present invention is to provide a kind ofly both to have had PTC intensity height, good temperature-control performance, limit the little characteristics of fluctuation of temperature, the CABLE MATERIALS stopping composition compsn that has better intensity, extensibility and flame retardant properties again certainly.
