Problems solved by technology

The core material in the middle of the insulating joint is mostly made of silicone rubber. During use, the insulating joint is likely to be in an outdoor environment. If it is used for a long time, the silicone rubber will gradually age and cause deformation and other problems.

Embodiment Construction

[0018] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0019] like figure 1 As shown, a prefabricated silicone rubber core material for insulating joints, the core material is a long rod-shaped structure, the core material includes poured silicone rubber and at least one layer of braided layer cast in the silicone rubber, the outer layer of the braided layer The shape is consistent with the external shape of the core material, and the external shape and size of the braided layer are smaller than the external shape and size of the core material; the braided layer includes several warp threads parallel to the axial direction of the core material and weft threads spirally wound on several warp thread...

Abstract

The invention discloses a prefabricated silicone rubber core material used for an insulation joint. The core material is of a long-strip bar-shaped structure, and comprises silicone rubber formed by pouring and at least one braiding layer poured in the silicone rubber. The outer shape of each braiding layer is consistent with that of the core material. The size of the outer shape of each braiding layer is smaller than that of the outer shape of the core material. Each braiding layer comprises multiple warps parallel to the axis of the core material, and multiple wefts sprially wound on the warps. The warps and the wefts are mutually interlaced. By integrating the braiding layers in the current silicone rubber core material, the whole structure intensity of the silicone rubber is improved; in particular, each braiding layer has the warps and the wefts, so the structure intensity of the core material in the axial and radial directions can be improved; structure deformation caused by aging is slowed down; and service lifetime of the core material is prolonged.

Description

technical field [0001] The invention relates to an insulating material, in particular to a prefabricated silicon rubber core material used for insulating joints. Background technique [0002] Insulated joints are a general term for pipeline joints that have both the sealing performance and strength performance required for buried steel pipelines and the insulation performance required for electrical corrosion protection. The core material in the middle of the insulating joint is mostly made of silicone rubber. During use, the insulating joint is likely to be in an outdoor environment. After a long period of use, the silicone rubber will gradually age and cause deformation and other problems. It is necessary to strengthen the structure of the existing silicone rubber core material in order to increase its effective service life. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art and provides a prefabricated silicon rubber core mate...
