Problems solved by technology

The UPVC pipes in the prior art are tested according to the GB / T5836.1-92 standard for drop hammer impact test. After years of testing, it is found that the one-pass rate is only less than 50%, and many products even break after 10 impacts. Therefore, the resistance of plastic pipes Poor impact
Doing so can indeed increase the softening temperature, but it will greatly reduce other properties of the pipe, especially the impact resistance, tensile strength and toughness.

Abstract

The invention discloses an enhanced electric power information cable conduit and a preparation method thereof. Materials of the cable conduit mainly comprise components as follows: CPVC (chlorinated polyvinyl chloride), PVC (polyvinyl chloride), ACR (an acrylic polymer), calcium carbonate, a calcium / zinc composite stabilizer, beta-diketone, hydrotalcite, spherical organosilicone micro-powder and a processing agent. The preparation method of the enhanced electric power information cable conduit comprises the steps as follows: putting all the components into a planetary mixer, and preparing a premix by full stirring; feeding the obtained premix into a double-screw extruder, and preparing a special CPVC tube material by melt extrusion, as well as air-cooling powder milling and particle cutting; feeding the special CPVC tube material into a single-screw extruder, extruding a tube blank in a molten state, subjecting the tube blank to forming, cooling, drawing, cutting and stacking, and obtaining the enhanced electric power information cable conduit. According to the enhanced electric power information cable conduit, a dispersion strengthening technology is used, and rigid particles, namely, spherical organosilicone micro-powder, are taken as a second phase and uniformly distributed in a CPVC phase in a manner of fine and dispersed particles, therefore, a reinforcement effect is generated, and the comprehensive performance of the tube material is improved.

Description

technical field [0001] The invention relates to the technical field of plastic pipes, in particular to a cable guide for laying wires and cables and a preparation method thereof. Background technique [0002] With the rapid development of electric power industry and information industry, power information cables have been widely promoted in urban construction and renovation, making cable laying and threading conduits more and more widely used. There are many types of cable laying conduits, such as traditional plastic pipes, cast iron pipes, galvanized steel pipes, cement pipes, etc. Plastic cable laying conduit, because of its advantages of energy saving, ecological protection, and convenient construction, has a wide range of applications and has become the main force of the urban construction pipe network in the new century. In particular, the widespread use of new environmentally friendly plastic pipes has set off a revolution to replace traditional pipes. [0003] Plasti...
