Abstract
The invention discloses crush-resistance light cable filler and a manufacturing method thereof. The crush-resistance light cable filler comprises, by weight, 20-22 parts of EPDM rubber, 5-7 parts of modified hard clay, 7-9 parts of natural mica, 4-6 parts of kaolin, 2.5-3.5 parts of silane coupling agent, 1.5-2.5 parts of flame retardant, 0.4-0.8 part of antioxygen, 1.2-1.8 parts of white carbon black, 3-5 parts of silicium-calcium slag, 0.5-1.4 parts of silicone oil, 2.2-3.2 parts of glass beads and 0.3-0.9 part of volcanic ash. Cable gaps can be fully filled, the roundness of the appearance in the cable forming process is guaranteed, and the crush-resistance light cable filler further has the advantages of being high in mechanical strength, good in surface sealing property, capable of achieving the crush-resistance function and low in weight.
Description
Technical field
The present invention relates to CABLE MATERIALS preparation field, specifically belong to a kind of resistance to compression lightweight cable filler and preparation method thereof.
Background technology
The traditional cable stopping composition produced on the market at present mainly contains following three kinds: 1) the fan-shaped packing that extrudes of crosslinked polyethylene waste material; 2) polypropylene (PP) grid gasket for packing; 3) polyvinyl chloride or rubber hose packing.This several packing is due to the reason of its material, formula or shape, existing defects is as follows: the fan-shaped packing that crosslinked polyethylene waste material extrudes: this packing adopts crosslinked polyethylene waste powder particle material to make base-material, and interpolation caking agent, filler, colorant extrusion molding form.Because crosslinked polyethylene is thermosetting resin, it is very poor that it reclaims waste material meltbility when secondary processing, needing to add a large amount of caking agents comes shaping, therefore this is filled with following defect: surface irregularity, size specification is uneven, can not abundant filled cable space, and the roundness of outward appearance when ensureing cable cabling; Tensile strength is little, and frangibility when stranding is filled, affects production rate; Weight is convenient operation very much not; Deposit the easy moisture absorption in process, bring hidden danger of quality to product.
Summary of the invention
The object of this invention is to provide a kind of resistance to compression lightweight cable filler and preparation method thereof, energy is filled cable space fully, ensure that the rounding of outward appearance during cable cabling; And it is high to have physical strength, face seal is good, has the advantage of resistance to compression and lightweight.
Technical scheme of the present invention is as follows:
A kind of resistance to compression lightweight cable filler, each raw material is as follows with parts by weight: terpolymer EP rubber 20 ~ 22 parts, 5 ~ 7 parts, modified hard potter's clay, natural mica 7 ~ 9 parts, kaolin 4 ~ 6 parts, silane coupling agent 2.5-3.5 part, fire retardant 1.5 ~ 2.5 parts, 0.4 ~ 0.8 part, oxidation inhibitor, white carbon black 1.2 ~ 1.8 parts, calcium silicate slag 3 ~ 5 parts, silicone oil 0.5 ~ 1.4 part, glass microballon 2.2 ~ 3.2 parts, volcanic ash 0.3 ~ 0.9 part;
A making method for resistance to compression lightweight cable filler, includes following operation steps:
1), by above-mentioned parts by weight, after terpolymer EP rubber, modified hard potter's clay, natural mica, kaolin and suitable quantity of water stir, reactor is loaded, when being then warming up to 80-90 DEG C, insulation 20-25 minute, takes out, dry, pulverize last, cross 600-800 mesh sieve and get final product;
2) by step 1) product and white carbon black, calcium silicate slag, glass microballon put into high-speed mixer, and after high-speed mixing 20 ~ 30min, then add surplus stock in mixing machine, after high-speed mixing 10 ~ 20min, be cable filler.
Containing modified hard potter's clay, natural mica, calcium silicate slag in raw material of the present invention, these raw materials have the feature of resistance to compression and lighter weight, and energy is filled cable space fully, ensure that the rounding of outward appearance during cable cabling; And it is high to have physical strength, face seal is good, and have the advantage of resistance to compression and lightweight, preparation is simple, is convenient to suitability for industrialized production, constant product quality.
