Embodiment Construction

[0017] The present invention will be further described in detail below through the specific examples, the following examples are only descriptive, not restrictive, and cannot limit the protection scope of the present invention with this.

[0018] A waterproof adhesive tape for cables, comprising an inner layer and an outer layer, the inner layer is a waterproof layer, the outer layer is a reinforcement layer, and the reinforcement layer is thermally sealed on the waterproof layer, wherein the raw material components and proportions of the waterproof layer are:

[0019]

[0020] The reinforcement layer is in the shape of a belt, which is made of high-strength glass fiber 6Kg, nylon fiber 1Kg, and polypropylene fiber 3Kg according to the ratio of rhombus pattern.

[0021] The preparation method of above-mentioned waterproof adhesive tape is:

[0022] It is to dissolve polyvinyl alcohol in tetralin at 100-150°C, wait for it to cool to 60°C, and then add amyl acetate, industri...

Abstract

The invention relates to a waterproof adhesive tape for a cable and a preparation method of the waterproof adhesive tape. The waterproof adhesive tape comprises an inner layer and an outer layer, wherein the inner layer is a waterproof layer; the outer layer is a reinforced rib layer; the reinforced rib layer is arranged on the waterproof layer in a thermal binding manner. The adhesive tape provided by the invention adopts a double-layer structure; due to the adoption of the reinforced rib layer, the stretchability of the adhesive tape is effectively improved; due to the adoption of the waterproof layer, adhesive tapes can be combined and dissolved with each other, so that a sealed integral part is formed after a part to be sealed is winded by the sealing waterproof adhesive tapes, and the material used in the waterproof adhesive tape can be used at the temperature of minus 10 DEG C to 200 DEG C.

Description

technical field [0001] The invention belongs to the field of cable protection tools, in particular to a waterproof adhesive tape used for cables and a preparation method thereof. Background technique [0002] With the wide application of new technology cold shrinkable cable intermediate joints, the weakness of its waterproof performance has been gradually exposed after long-term operation. In addition, the cable will inevitably be damaged during laying, which will lead to water ingress in the outer sheath, especially groundwater. In cities with high water levels, the result of cable flooding is that cable failures occur frequently. [0003] At present, the damaged part of the cable intermediate joint and or the outer sheath of the cable is fixed and waterproofed by adhesive tape, but after long-term use, obvious damage occurs, mainly due to the decrease of the adhesive force of the tape and the aging of the tape. In some environments, the tape is corroded and damaged, which...
