Embodiment 1

[0016] A cable sheath insulating material for field logging, which is composed of the following raw materials in parts by weight (kg):

[0017] Neoprene A90 102, Japan JSR nitrile rubber N220S21, semi-reinforced carbon black N774 26, ferrocene 2, N, N'-m-phenylene bismaleimide 2, barium sulfate powder 31-36, anti-aging Agent MB 3, 2-mercaptobenzimidazole 1, chlorinated paraffin 9, accelerator DM2, ammonium trimolybdate 1, nano bauxite 29, propylene glycol adipate polyester 3, zinc borate 4, epoxy oil Butyl acid 6, zinc oxide 0.8, modified calcium carbonate 2, bispentamethylenethiuram hexasulfide 2, isopropyl tris(dioctyl pyrophosphate acyloxy) titanate 1.2, ammonium polyphosphate 3;

[0018] The preparation method of the modified calcium carbonate is as follows: mix quicklime and boiled water at a mass ratio of 1:10, digest for 5 hours, filter and remove slag through a 180 μm resonance sieve, and then further remove slag through a hydrocyclone to obtain Ca(OH) 2 Suspension, ...

Abstract

The invention discloses a cable sheath insulating material for field logging and a preparation method of the cable sheath insulating material. The cable sheath insulating material comprises the following raw materials according to parts by weight: 97 to 102 parts of neoprene A90, 14 to 21 parts of Japanese JSR chemigum N220S, 19 to 26 parts of semi-reinforcing black N774, 2 to 3 parts of ferrocene, 1 to 2 parts of N, N'-m-phenylenedimaleimide, 31 to 36 parts of blanc fixe, 1 to 3 parts of anti-aging agent MB, 1 to 2 parts of 2-thiol benzimidazole, 5 to 9 parts of chlorcosane, 1 to 2 parts of accelerant DM, 0.8 to 1 part of ammonium trimolybdate, 19 to 29 parts of nanometer bauxite, 1 to 3 parts of polypropylene glycol adipate, 2 to 4 parts of zinc borate, 4 to 6 parts of epoxidized butyl ester, 0.8 to 1 part of zinc oxide, 2 to 3 parts of modified calcium carbonate, 1 to 2 parts of hexasulfide dipentamethylenethiuram, 1 to 1.2 parts of isopropyl tri(dioctyl pyrophosphoric acyloxy) titanate, and 2 to 3 parts of ammonium plyphosphate. The cable sheath insulating material for field logging, prepared by the invention, is excellent in physical performance, stable in dimension and low in percentage of contraction, and greatly reduces the pulling strength, the tearing strength and the resilience performance.

Description

technical field [0001] The invention mainly relates to a rubber sheath material and a preparation method thereof, in particular to a cable sheath insulating material for field logging and a preparation method thereof. Background technique [0002] Due to the special working environment of the cable used for field logging, it has been in the dirty underground for a long time. The outer sheath of the cable is relatively strongly corroded by the outside world, and it also needs to withstand frequent twisting and certain tension. Therefore, the outer sheath of the cable is relatively strong The mechanical properties, water resistance, aging resistance, and corrosion resistance of the sheath are very demanding. The rubber sheath of ordinary cables cannot meet the requirements of this specific workplace, and the service life is often very short. Contents of the invention [0003] The object of the present invention is to provide a cable sheath insulating material for field loggi...
