Heat tracing cable sheath material capable of preventing growth of mildew and preparation method of heat tracing cable sheath material

Abstract

The invention discloses a heat tracing cable sheath material capable of preventing growth of mildew 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: 35-55 parts of ultra-high molecular weight polyethylene, 22-34 parts of nylon 11, 17-26 parts of a cyclic olefin copolymer, 10-15 parts of germanite powder, 8-14 parts of tourmaline powder, 5-10 parts of tetrachloroisophthalonitrile, 6-12 parts of dicyclohexyl phthalate, 2-4 parts of zinc undecylenate, 3-6 parts of tri(2,3- dibromopropyl)isotriazinetriol ester, 10-15 parts of organic bentonite, 5-7 parts of n-butyl stearate, 1-2 parts of caprylic-capric neodymium, 2-3 parts of cadmium laurate, 4-8 parts of ammonium fluoroborate, 5-10 parts of tri(2-chloroethyl)phosphate, 1-2 parts of dodecyl dimethyl benzyl ammonium bromide and 3.5-5.5 parts of an aid. The heat tracing cable sheath material has excellent mildew-proof and antibacterial property and is capable of preventing the growth, generation and breeding of the mildew at a humid environment, so that a heat tracing cable cannot be encroached by the mildew; meanwhile, the heat tracing cable sheath material has excellent weather resistance, heat resistance, fire resistance and corrosion resistance, so that the service life of the cable is greatly prolonged, a lot of unnecessary losses can be avoided, and the use coat of the cable is lowered.

Description

technical field [0001] The invention relates to an anti-mold growth 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 environment, the h...
