Problems solved by technology

The cable usually includes a core, an insulating layer, an inner sheath and a sheath tube in order from the inside to the outside. The sheath tube is the outermost layer of the cable and is also the main protective component of the whole. Most of them are mainly made of polyethylene, polypropylene, Made of polymer materials such as polyvinyl chloride, although it has good corrosion resistance properties, its mechanical strength and other properties are usually poor, and further improvement is needed
At present, people mostly add inorganic filler components to it to improve, but the surface activity of ordinary inorganic filler components is not good, and the compatibility, combination and dispersion with polymer materials are not good, resulting in poor filling effect. Urgent need to improve

Abstract

The invention discloses a preparation method of a filler for increasing the strength of a cable sheathing pipe. The method comprises the following steps: (1) preparation of raw materials, (2) pretreatment of the raw materials, (3) preparation of a modified treatment liquid, and (4) modification of the raw materials. The filler is specially prepared by the method, and the filler has very good surface activity, can effectively improve the mechanical strength characteristics in the preparation of the cable sheathing pipe, can enhance the corrosion resistance and temperature resistance of the cable sheathing pipe, and has good promotion and use value.

Description

technical field [0001] The invention belongs to the field of electric facilities, and in particular relates to a preparation method of a filler for improving the strength of a cable sheath tube. Background technique [0002] With the gradual acceleration of the urbanization process, urban planning is becoming more and more modern. In the process of urban construction, cable entry into the ground has become the minimum construction requirement. At the same time, in the process of urban transformation, it is also necessary to put various cables erected in the air into the ground. At present, the construction of cables into the ground often adopts the non-excavation technology. This construction method has the advantages of no impact on traffic, little damage to the stratum structure, and short cycle time. The cable usually includes a core, an insulating layer, an inner sheath and a sheath tube in order from the inside to the outside. The sheath tube is the outermost layer of...
