Abstract
The invention discloses an optical cable semi-rigid plastic protective bushing. The optical cable semi-rigid plastic protective bushing comprises the following components in parts by weight: 50 to 70 parts by weight of chlorinated polyvinyl chloride, 30 to 50 parts by weight of polyvinyl chloride, 3 to 5 parts by weight of adhesiveness-increasing resin, 1.2 to 2 parts by weight of composite stabilizers, 1 to 2 parts by weight of flame retardants, 5 to 30 parts by weight of methacrylic acid-butadiene-styrene ternary polymerization resin, 0.02 to 0.05 part by weight of carbonate calcium, and 5 to 8 parts by weight of flexibilizers. According to the optical cable semi-rigid plastic protective bushing of the invention, polymers such as the composite stabilizers, the methacrylic acid-butadiene-styrene ternary polymerization resin and the carbonate calcium are added into the components of the optical cable semi-rigid plastic protective bushing, and therefore, the optical cable semi-rigid plastic protective bushing has the advantages of simple processing, smooth surface and easiness in construction, and the vicat softening point of the optical cable semi-rigid plastic protective bushing is not lower than 930 DEG C, so that the optical cable semi-rigid plastic protective bushing further has the advantages of high pressure resistance and heat resistance.
Description
Technical field
The present invention relates to a kind of optical cable semi-hard plastic protecting pipe.
Background technology
Long distance optical cable adopts large length semi-hard plastic pipe to lay, and can simplify the shielding layer structure of optical cable, reduce project cost, laying of pipeline can be staggered with the construction period of optical cable, not by seasonal effect, was convenient to construction in summer, investment reduction.Pipeline plays mechanical protection effect, improves the mildew-resistant of whole communication cable circuit, corrosion protection, protection against rodents ability.
Large length plastic tube adopts PE to be the manufacture of materials of main body, and it has enough rigidity, has again certain flexibility and less coefficient of friction, makes in construction.This product is being applicable to outside fiber cable laying, also will for laying of common communication cable and laying of the cable such as street lamp power cable.
But existing optical cable semi-hard plastic protecting pipe self-repairing capability is poor, and useful life is short.
