Embodiment 1

[0011] A kind of compression-resistant lightweight cable filler, the raw materials are as follows in parts by weight: 21 parts of EPDM rubber, 6 parts of modified hard clay, 8 parts of natural mica, 5 parts of kaolin, 3 parts of silane coupling agent, 2 parts of flame retardant, 0.6 parts of antioxidant, 1.5 parts of white carbon black, 4 parts of silicon calcium slag, 1 part of silicone oil, 3 parts of glass beads, 0.6 part of pozzolan;

[0012] A method for making a compression-resistant lightweight cable filler, comprising the following steps:

[0013] 1) According to the above parts by weight, after mixing EPDM rubber, modified hard clay, natural mica, kaolin and appropriate amount of water, put it into the reaction kettle, then heat it up to 85°C, keep it warm for 22 minutes, take it out, and dry it , After being ground into powder, pass through a 700-mesh sieve;

[0014] 2) Put the product of step 1), white carbon black, silicon-calcium slag, and glass beads into a high...

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 [0001] The invention relates to the field of cable material preparation, in particular to a compression-resistant lightweight cable filler and a manufacturing method thereof. Background technique [0002] There are three main types of traditional cable fillers currently on the market: 1) Fan-shaped filler strips extruded from cross-linked polyethylene waste; 2) Polypropylene (PP) mesh filler ropes; 3) PVC or rubber tube fillers strip. Due to their material, formula or shape, these kinds of filling strips have the following defects: Fan-shaped filling strips extruded from cross-linked polyethylene waste: the filling strips use cross-linked polyethylene waste crushed pellets as the base material, adding adhesive Agents, fillers, and colorants are extruded. Since cross-linked polyethylene is a thermosetting plastic, its recycled waste has poor melting properties during secondary processing, and a large amount of adhesive needs to be added to form it. Therefore...
