Abstract

The invention relates to a cable sleeve, particularly a novel energy-saving high-heat-dissipation-property PVC (polyvinyl chloride) cable sleeve. The invention aims to provide a PVC cable sleeve which has the advantages of high temperature resistance, favorable aging resistance, high insulating strength, high volume resistivity, favorable flexibility and high compression strength. The technical scheme is as follows: the novel energy-saving high-heat-dissipation-property PVC cable sleeve comprises the following raw materials in percentage by weight: 5-10% of stabilizer, 3-5% of lubricant, 3-5% of filler, 1-2% of toner, 1-2% of compression resisting agent, 1-2% of other materials and the balance of PVC resin. The preparation method comprises the following steps: grinding raw materials into powder with the fineness of 80-100mm; evenly mixing the raw material powder obtained in the previous step at 135-150 DEG C; and respectively adding the mixture obtained in the previous step into two conical double screw extruders to coextrude cable sleeves, wherein the working temperature of the conical double screw extruders is 180-210 DEG C.

Description

technical field [0001] The invention relates to a cable casing, in particular to a novel PVC cable casing with energy saving and good heat dissipation. Background technique [0002] Cable casing is a new type of casing material popularized and used in electric power engineering. With the rapid development of power cable buried laying projects, higher requirements are put forward for cable casings. [0003] At present, the cable casing for engineering is made of polyvinyl chloride resin as the main material, heavy calcium carbonate as the filler, and chlorinated polyethylene, paraffin and other small materials, and has certain corrosion resistance, high temperature resistance, flame retardancy, Insulation, wear resistance, light weight, no pollution and other characteristics. However, its shortcomings are poor compressive strength, which is still far behind the requirements of construction and application, and its flame retardant performance is not ideal; in addition, its V...
