Abstract

The invention discloses a low-temperature reinforced type heating cable sheathing material and a preparation method thereof. The low-temperature reinforced type heating cable sheathing material is prepared from the following raw materials in parts by weight: 36-52 parts of nylon 66, 24-48 parts of polytetrafluoroethylene, 18-32 parts of polyamide imide, 10-15 parts of low-molecular-weight polybutylene, 14-18 parts of magnesium borate whiskers, 12-16 parts of illite powder, 10-15 parts of tetraethylene glycol diheptylate, 5-10 parts of nano zirconium boride, 3-5 parts of magnesium oleate, 8-14 parts of diisodecyl adipate, 4-6 parts of aluminum hydroxydistearate, 6-9 parts of caprylic/capric triglyceride, 10-15 parts of dioctyl sebacate, 5-10 parts of epoxy fatty acid methyl ester, 1-2 parts of polyethylene oxide sorbitan monoleate and 3-4 parts of auxiliaries. The low-temperature reinforced type heating cable sheathing material has good low-temperature resistance, a low-temperature brittleness temperature up to -45 DEG C, extremely good mechanical strength and excellent corrosion resistance, ageing resistance and abrasive resistance, and is durable in use and wide in range of application.

Description

technical field [0001] The invention relates to a low-temperature reinforced heat tracing cable sheath material and a preparation method thereof, belonging to the field of cable sheath 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 environme...
