Problems solved by technology

[0003] The domestic existing technology mainly uses organic matter to fill the space between the gaps after chemical reaction expansion and solidification, so as to achieve the function of sealing cables or pipes, which has the following disadvantages: 1. Since the paving sealing material has been cured, it cannot be directly upgraded or expanded. Maintenance needs to be inspected and replaced when the cables or pipes have to be removed before the cured sealing body can be implemented. After the replacement is completed, the sealing body needs to be filled again, which will cause damage to the installed cables; 2. When the number of cables is large, the construction is difficult and the airtight effect bad

preparation example Construction

[0081] The present invention also provides a preparation method of each component material, and the preparation method is a conventional technique in the field. Such as compounding and supplementary processing → raw rubber and compounding agent weighing → mixing → quality inspection.

[0082] The processing method of the base diaphragm is as follows:

[0083] Preparation process: heat refining (adding initiator and vulcanizing agent according to the corresponding proportion of the material) → blanking → vulcanization (vulcanization parameters of standard thickness: 180°C, 6min, pressure 20MPa, the actual vulcanization time of the matrix is ​​calculated according to the equivalent vulcanization time, The pressure is calculated according to the area of ​​the parting surface)→trimming→finished product.

[0084] The preparation methods not mentioned in the present invention are all conventional preparation methods in this field.

[0085] The materials used in the present inventi...

Abstract

The invention provides a cable pipeline sealing module. The cable pipeline sealing module comprises a base material, a rubber diaphragm, an expansion unit material and a blockage core rod. The cable pipeline sealing module in the invention has the performances that: (1), redundancy design is supported; therefore, a sealing system using the sealing module has the expansion capability in a design interval; and an expansion space can be reserved for cable or pipeline upgrading and reconstruction; (2), installation is simple and convenient; and a convenient condition is provided for later maintenance and cable inspection; (3), the sealing performance cannot be reduced by change of the cable or pipeline size tolerance; (4), the module has excellent air aging or oil resisting performance; and (5), the sealing performance when a cable or pipeline passes through a container in a low-voltage container can be improved; and the module can work in a high-temperature and ozone environment for a long time.

Description

technical field [0001] The invention relates to sealing materials, more specifically to a cable duct sealing module. Background technique [0002] Cable and pipeline sealing systems are widely used in power telecommunications, petrochemical, sewage treatment, shipbuilding, ocean engineering, national defense, industrial and civil buildings, etc. In the event of a hazardous situation within a given environment, sealing modules prevent flames, smoke, gas and water from reaching adjacent structural parts through cable and pipe penetrations. [0003] The domestic existing technology mainly uses organic matter to fill the space between the gaps after chemical reaction expansion and solidification, so as to achieve the function of sealing cables or pipes, which has the following disadvantages: 1. Since the paving sealing material has been cured, it cannot be directly upgraded or expanded. Maintenance needs to be inspected and replaced when the cables or pipes have to be removed b...
