Problems solved by technology

However, the buoy communication cables used for ships work underwater for a long time, and the buoys continue to float with the water level. The cables have to withstand more frequent twisting and greater tension. The requirements for the insulation performance, corrosion resistance, and aging resistance of insulating rubber are relatively high. High, the insulating rubber of ordinary communication cables cannot meet the requirements of this specific workplace

Embodiment 1

[0016] A buoy communication cable sheath insulation material for ships, which is composed of the following raw materials in parts by weight (kg):

[0017] Neoprene S40V 105, thermoplastic polyurethane elastomer (BASF S90A, Germany) 20, epoxy dioctyl tetrahydrophthalate 0.7, sepiolite 20, ferrocene 2, N, N'-m-phenylene double horse Laimide 1, barium sulfate powder 35, antioxidant MB 2, triallyl isocyanuria 1.5, microcrystalline paraffin wax 5-9, accelerator DM 2, ammonium trimolybdate 0.8, nano-bauxite 23, Propylene glycol adipate polyester 1-3, zinc borate 4, epoxy butyl oleate 6, zinc oxide 1, modified fly ash 3, bispentamethylene thiuram hexasulfide 2;

[0018] The preparation method of the modified fly ash is as follows: add the fly ash to 1.2g / L potassium permanganate solution and 10% sodium hydroxide solution for soaking to remove impurities, then filter and wash to make it neutral, and calcinate at 450°C , 1 hour, grind into powder, then add 2% of the powder weight of q...

Abstract

The invention discloses a buoy communication cable sheath insulating material for ships and a preparation method thereof. The insulating material is prepared from the following raw materials in parts by weight: 95-105 parts of chloroprene rubber S40V, 15-20 parts of thermoplastic polyurethane elastomer (badische aniline soda fabric S90A), 0.7-1 part of di(2-ehtylhexyl) 4, 5-epoxy tetrahydrophthalate, 14-20 parts of sepiolite, 2-3 parts of ferrocene, 1-2 parts of N, N'-m-phenylene dimaleimide, 31-35 parts of blanc fixe, 1-2 parts of anti-aging agent MB, 1.5-2 parts of triallyl isocyanurate, 5-9 parts of microcrystalline wax, 1-2 parts of accelerator DM, 0.8-1 part of ammonium molybdate, 15-23 parts of nano bauxite, 1-3 parts of poly(1,2-propylene glycol adipate), 2-4 parts of zinc borate, 4-6 parts of epoxy fatty acid butyl ester, 0.8-1 part of zinc oxide, 2-3 parts of modified fly ash and 1-2 parts of hexasulfide bis(1-piperidinylthioxomethyl). The produced buoy communication cable sheath insulating material for the ships has excellent physical performance, stable dimensions and low shrinkage factor, and the tensile strength, tear resistance and elastic force performance of a product are all greatly improved.

Description

technical field [0001] The invention mainly relates to a rubber sheath material and a preparation method thereof, in particular to a buoy communication cable sheath insulating material for ships and a preparation method thereof. Background technique [0002] There are many kinds of communication cables on the market, most of which use multi-strand insulated cores to twist and extrude the outer sheath, which can meet the requirements of general communication cables. However, the buoy communication cables used for ships work underwater for a long time, and the buoys continue to float with the water level. The cables have to withstand more frequent twisting and greater tension. The requirements for the insulation performance, corrosion resistance, and aging resistance of insulating rubber are relatively high. High, the insulating rubber of ordinary communication cables cannot meet the requirements of this specific workplace. Contents of the invention [0003] The object of t...
