Abstract

The invention discloses a CPVC power cable protecting tube and belongs to the technical field of protecting tubes. The CPVC power cable protecting tube comprises the following raw materials in parts by weight: 60-70 parts of CPVC resin, 8-10 parts of methacrylic-butadiene-styrene ternary copolymerized resin, 11-15 parts of polyether-ether-ketone, 12-14 parts of poly para phenylene benzo bioxazole fibers, 9-11 parts of carbon fibers, 15-17 parts of calcium carbonate, 7-9 parts of silicon dioxide, 3-6 parts of glass-ceramic powder, 5-7 parts of aluminium oxide, 2-4 parts of white oil, 1-5 parts of ethylene bis stearamide, 7-9 parts of a CPE impact modifier, 6-10 parts of an ACR processing aid, 13-17 parts of a plasticizer, 1-4 parts of a heat stabilizer and 1-2 parts of an ultraviolet adsorbent. The invention also discloses a preparation method of the CPVC power cable protecting tube. The CPVC power cable protecting tube disclosed by the invention is excellent in mechanical strength and has relatively excellent high-temperature flame retardance.

Description

technical field [0001] The invention relates to the technical field of protection tubes, in particular to a CPVC power cable protection tube and a preparation method thereof. Background technique [0002] Cable protection tube is also known as cable tube, power cable tube, cement cable tube, power row tube, power cable protection tube, etc. The cable protection tube is mainly installed at the intersection of communication cables and power lines to prevent short-circuit accidents caused by disconnection of power lines, causing communication cables and steel wire ropes to be charged, so as to protect cables, switches, core boards, and the whole machine from being burned out. Magnetic field interference also plays a certain role in isolation. [0003] With the development of the times, composite materials made of cement or other metals or non-metals are gradually replaced by plastic protection tubes. Most cable protection tubes made of modified high-strength plastics can impro...
