Problems solved by technology

[0004] 1. The airtight performance of the existing cable seals is not enough, and water often penetrates into the seals and contacts with the cables, resulting in short circuits and potential safety hazards;
[0005] 2. The existing cable seals are easy to age and difficult to replace, and their functions are relatively single, and the service life of the materials is short. If they are not replaced in time, they will often cause safety hazards;
[0006] 3. The existing cable sealing modules are basically molded by high temperature curing, which is cumbersome and costly

Abstract

The invention discloses a high-sealing-performance waterproof anti-aging cable sealing element. The high-sealing-performance waterproof anti-aging cable sealing element is characterized in that a basematerial for injection molding is prepared from the following components in parts by weight: 110-120 parts of isocyanate, 100 parts of polyol, 100 parts of vinyl-terminated polydimethylsiloxane, 2-4parts of phenylene silicone rubber, 2-4 parts of p-terphenyl, 2-4 parts of m-terphenyl, 10-30 parts of chopped alkali-free glass fibers, 5 parts of maleic anhydride functionalized polypropylene, 0.5 parts of gamma-amidino thiopropyl tri-hydroxyl silane, 0.5 parts of polyethylene wax, 1 part of 4[beta-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester and 1 part of (2'-hydroxy-3'-tertiary butyl-5'-methylphenyl)-5-chlorobenzotriazole.

Description

Technical field [0001] The invention belongs to the field, and particularly relates to a high-sealing waterproof and anti-aging cable seal. Background technique [0002] With the development of society, the degree of electrification in many fields continues to increase, and it is often necessary to pass cables or other pipelines through different spacers. In order to prevent the medium on both sides of the spacer from being exchanged, and to maintain the medium pressure, temperature, composition and cleanliness of the required space, it is necessary to seal the cable or pipeline through. [0003] At present, there are mainly the following problems: [0004] 1. The existing cable seals have insufficient airtight performance, and water often penetrates into the seals and contacts the cable, resulting in a short circuit phenomenon, causing safety hazards; [0005] 2. The existing cable seals are easy to age and are not easy to replace, and the function is relatively single, and the serv...
