Heat tracing cable sheath material for thermal oil recovery and preparation method of heat tracing cable sheath material

Abstract

The invention discloses a heat tracing cable sheath material for thermal oil recovery and a preparation method of the heat tracing cable sheath material. The heat tracing cable sheath material is prepared from the following raw materials in parts by weight: 40-60 parts of nylon 6, 25-35 parts of polyphenylene sulfide, 16-22 parts of a perfluoro(ethylene-propylene) copolymer, 10-15 parts of ash calcium powder, 8-12 parts of nano titanium phosphate, 10-15 parts of volcanic rock powder, 3-6 parts of basic lead carbonate, 5-10 parts of dibutyl fumarate, 2-3 parts of tri(ethyl laurate thiol) antimony, 1.5-2.5 parts of triphenyl phosphite, 3-5 parts of trimethylolpropane, 4-8 parts of sasol wax, 1-2 parts of tetraphenyl bisphenol-A-diphosphate, 10-15 parts of diethylene glycol dibenzoate, 8-14 parts of aluminum hypophosphite, 1-2 parts of 2,3,4-trihydroxybenzophenone and 2-4 parts of auxiliary agents. The sheath material disclosed by the invention has excellent heat resistance and oil resistance and good wear resistance, fatigue resistance and aging resistance, is safe and reliable, is long in service life, and ensures that the requirements for working environments of thermal oil recovery can be completely met.

Description

technical field [0001] The invention relates to a heating cable sheathing material for thermal oil recovery and a preparation method thereof, belonging to the field of cable sheathing materials. Background technique [0002] The heating cable is composed of a conductive polymer, two parallel metal wires, an insulating layer, and an outer sheath layer. It has high thermal efficiency, energy saving, simple design, convenient construction and installation, no pollution, and long service life. With the advantages of remote control and automatic control, it can be widely used in heat preservation, antifreeze and anticondensation of pipelines, pump bodies, valves, tanks and tank volumes in petroleum, chemical, electric power, medicine, machinery, food, shipbuilding and other industries. It is the most advanced and effective method to maintain the process temperature of the infusion pipeline and the liquid storage medium tank. Due to the limitations of the laying or use environmen...

AI Technical Summary

Problems solved by technology

At present, the sheathing materials used for heating cables for thermal oil recovery in the market have the disadvantages of poor heat resistance and oil resistance. Working in oil medium and high temperature environment for a long time, the sheath layer is prone to aging and cracking.
