Embodiment 1

[0023] The preparation of a novel watertight material comprises the following steps:

[0024] 1) Take 20 parts of chloroprene rubber and add it to the pulverizer for crushing. The crushing time is 30 minutes, and the size of the crushed particles is 120 mesh. Part joins in pulverizer and pulverizes, and pulverization time is 15 minutes, and the number of pulverized particle order is 140 orders, and 15 parts of glass fibers that pulverized are taken out and set aside for subsequent use;

[0025] 2) Take 8 parts of pure acrylic emulsion, 15 parts of polyvinyl chloride and 18 parts of waterproof powder and add them to the mixer for mixing and stirring. The stirring temperature is 40°C and the stirring time is 5 minutes. After the stirring is completed, pour the mixed materials into a clean container reserved for use;

[0026] 3) Turn on the power of the internal mixer, preheat the internal mixer, check whether the wind pressure, water pressure and voltage meet the process requir...

Abstract

The invention relates to the technical field of waterproof sealing materials, and discloses preparation of novel watertight materials. The preparation includes steps of 1), adding 20-24 parts of chloroprene rubber into a smashing machine, smashing the chloroprene rubber for the smashing time of 30-40 minutes to obtain smashed particles with the mesh numbers of 120-170 meshes, taking out 20-24 parts of smashed chloroprene rubber, reserving the smashed chloroprene rubber for standby application, then adding 15-17 parts of glass fibers into the smashing machine, smashing the glass fibers for thesmashing time of 15-19 minutes to obtain smashed particles with the mesh numbers of 140-180 meshes, taking out 15-17 parts of smashed glass fibers and reserving the smashed glass fibers for standby application. The preparation of the novel watertight materials and application of the novel watertight materials to watertight cable products have the advantages that cables can withstand long-term twisting and shrinking, the problem of influence on the waterproof sealing performance of existing cables after the existing cables are abraded can be solved, the waterproof sealing performance of the novel watertight materials can be effectively enhanced, and the novel watertight materials are insoluble in water, are long in service life, durable in use and low in cost and can be used as waterproof sealing materials to be effectively utilized in the cable products for a long term.

Description

technical field [0001] The invention relates to the technical field of waterproof sealing materials, in particular to the preparation of a novel watertight material and its application in watertight cable products. Background technique [0002] It is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other and is often twisted around a center. The entire outer surface is covered with a highly insulating coating. The cable has an inner Due to the characteristics of electrification and external insulation, power cables need to be arranged in some humid and rainy areas, and the cables need to have good water resistance and corrosion resistance, so the cables must be waterproof. [0003] In the fields related to fire protection such as underground streets, high-rise buildings and underground streets, the long-term torsion and shrinkage of the cables often cause the bending stress and twisting stress of the cables t...
