Abstract

The invention relates to a special Half-type communication cable protection sleeve for seafloor. The special Half-type communication cable protection sleeve comprises the following components in parts by weight: 100 parts of polyvinyl chloride or chlorinated polyvinyl chloride or a mixture of both, 3-5 parts of stabilizer, 5-15 parts of toughening agent, 2-3 parts of processing aid, 1-2 parts of lubricant, 3-5 parts of biological repellent and 5-10 parts of acid and alkali resistant modifier; or the chlorinated polyvinyl chloride comprises the following components in parts by weight: 100 parts of polyolefin, 5-15 parts of toughening agent, 3-5 parts of biological repellent and 5-10 parts of acid and alkali modifier. When the special Half-type communication cable protection sleeve is manufactured, all materials, expect the acid and alkali resistant modifier, are blended and extruded to obtain the Half-type communication cable protection sleeve, and then the acid and alkali resistant modifier is sprayed on the outer surface of the protection sleeve, wherein the spraying thickness is 0.3-2mm. The special Half-type communication cable protection sleeve is reasonable in material selection and is suitable for protecting communication cables in the seafloor, a seafloor mounting process is simplified and requirements of complicated seafloor conditions are met.

Description

technical field [0001] The invention belongs to the technical field of telecommunication cable protection sleeves, and in particular relates to a half-type telecommunication cable protection sleeve specially used for seabeds. Background technique [0002] Nowadays, the technology of erecting telecommunication cables on the seabed is becoming more and more mature, and the telecommunication cables need to be erected on the seabed together with the protective casing, which is used to protect the telecommunication cables. The condition of the seabed is more complicated, there are seawater entrained sea sand abrasion protection casings, seawater acid-base corrosion protection casings, seawater torrent impact protection casings, seabed animal bite protection casings, and poor installation environment on the seabed, etc. The wear resistance, acid and alkali corrosion resistance, and impact resistance of the protective sleeve in the prior art are not enough, and the installation on ...
