Embodiment 1

[0043] A metal tape for optical cable sheath, such as figure 2 As shown, the metal base strip 1 is included, and the inside of the metal base strip 1 is coated with two water-blocking grease lines 2 with a line width of 5mm. These two water-blocking grease lines 2 are respectively the horizontal water-blocking grease line 4 and the wave resistance Water grease line 5. Among them, the horizontal water-blocking grease line 4 is parallel to the edge of the metal base strip 1 and coincides with the central axis of the metal base strip 1; the wavy water-blocking grease line 5 is bent back and forth around the horizontal water-blocking grease line 4 to form a continuous broken line, wave The bending point 6 of the water-blocking grease line 5 is flush with the edge of the metal base strip 1, and the angle α between the bending point 6 is 60°; the horizontal water-blocking grease line 4 and the wave water-blocking grease line 5 are on the metal Several water-blocking chambers 3 are...

Embodiment 2

[0048] A metal tape for optical cable sheath, such as figure 2 As shown, the metal base strip 1 is included, and the inside of the metal base strip 1 is coated with two water-blocking grease lines 2 with a line width of 5mm. These two water-blocking grease lines 2 are respectively the horizontal water-blocking grease line 4 and the wave resistance Water grease line 5. Among them, the horizontal water-blocking grease line 4 is parallel to the edge of the metal base strip 1 and coincides with the central axis of the metal base strip 1; the wavy water-blocking grease line 5 is bent back and forth around the horizontal water-blocking grease line 4 to form a continuous broken line, wave The bending point 6 of the water-blocking grease line 5 is flush with the edge of the metal base strip 1, and the angle α between the bending point 6 is 90°; the horizontal water-blocking grease line 4 and the wave water-blocking grease line 5 are on the Several water-blocking chambers 3 are stagg...

Embodiment 3

[0053] A metal tape for optical cable sheath, such as image 3 As shown, the metal base strip 1 is included, and the inside of the metal base strip 1 is coated with two water-blocking grease lines 2 with a line width of 5mm. These two water-blocking grease lines 2 are respectively the horizontal water-blocking grease line 4 and the wave resistance Water grease line 5. Among them, the horizontal water-blocking grease line 4 is parallel to the edge of the metal base strip 1 and coincides with the central axis of the metal base strip 1; the wave water-blocking grease line 5 is bent back and forth around the horizontal water-blocking grease line 4 at a frequency of 1 / 2π, A continuous cosine curve is formed, and the bending point 6 of the wavy water-blocking grease line 5 is flush with the edge of the metal base strip 1; Water blocking chamber 3.

[0054] The linear water-blocking ointment on the metal tape of the optical cable sheath in this embodiment is obtained by applying a ...

Abstract

The invention discloses an optical cable sheath metal belt and a preparation method and application thereof. The optical cable sheath metal belt comprises a metal base belt and at least two water-blocking factice lines arranged on the metal base belt, and the water-blocking factice lines are mutually staggered to form a plurality of water-blocking cavities. During preparation, water-blocking factice is continuously coated on the metal base belt in a line spraying mode to form at least two continuous and mutually staggered water-blocking factice lines, and the optical cable sheath metal belt is obtained. According to the invention, the water-blocking factice is coated on the metal belt in a line form, so that the coating process is simplified, the use amount of the water-blocking factice can be greatly reduced, and the production cost is reduced. A plurality of line-shaped water-blocking factice lines are coated, the water-blocking factice lines are mutually staggered to form the continuous water-blocking cavities which are arranged according to a specific rule, and after the optical cable is coated, formed water-blocking stripes are uniformly and continuously distributed according to the specific rule, so that the water-blocking effect is excellent; and the use amount of the water-blocking factice is reduced, and a good water-blocking effect can also be generated at the same time.

Description

technical field [0001] The invention belongs to the technical field of optical cable manufacturing, and in particular relates to an optical cable sheath metal strip and a preparation method and application thereof. Background technique [0002] Optical fiber cable is manufactured to meet optical, mechanical or environmental performance specifications. It is a communication communication that uses one or more optical fibers placed in a sheath as a transmission medium and can be used individually or in groups. cable assembly. Most of the optical cables produced in China adopt the structure of the outer sheath wrapped vertically by the metal tape, and the water seepage of the optical cable is an important indicator to check whether the finished optical cable is qualified. At present, the main reason for the water seepage of the optical cable is that the metal laps of the optical cable sheath cannot be effectively filled with an appropriate amount of cable paste and water seepa...
