Abstract

The invention relates to the technical field of communication optical cables, and discloses a communication optical cable which comprises a plastic film, waterproof cloth is wrapped in the plastic film, non-woven fabric adheres to the outer surface of the waterproof cloth, waterproof paint is smeared on the outer surface of the non-woven fabric, and the space between the waterproof cloth and the plastic film is filled with fireproof asbestos. According to the communication optical cable water-blocking material and the preparation method thereof, the plastic film has a good waterproof effect and is low in cost, the fireproof and flame-retardant properties of optical fibers are improved through the arranged fireproof asbestos, the use safety of the optical fibers is improved, a waterproof coating is arranged on the outer surface of the non-woven fabric, and the polyurethane emulsion is cured after being in contact with moisture in air, a layer of firm and tough seamless integral waterproof film is formed on the surface of the base layer, and the waterproof coating adopts a polyvinyl alcohol adhesive which is prepared by taking a polyvinyl alcohol aqueous solution as an adhesive material, so that the waterproof coating on the non-woven fabric does not fall off and is firmly bonded.

Description

technical field [0001] The invention relates to the technical field of communication optical cables, in particular to a water-blocking material for communication optical cables and a preparation method thereof. Background technique [0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. It is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. The optical cable is mainly composed of optical fiber (glass filament as thin as hair), plastic protective sleeve and plastic sheath. There is no metal such as gold, silver, copper and aluminum in the optical cable, and generally has no recycling value. An optical cable is a communication line in which a certain number of optical fibers form a cable core in a certain way, and is covered with a sheath, and some are also covered with an outer sheath to realize optical signal tran...
