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 power information cable conduit and a preparation method thereof. The components of cable conduit materials mainly include CPVC, PVC, ACR, calcium carbonate, calcium / zinc composite stabilizer, β-diketone, hydrotalcite, silicone spherical micropowder and processing aids. Its preparation method: put each component into a planetary mixer, and make a premix after thorough stirring; send the prepared premix into a twin-screw extruder, melt extrusion and air-cooled grinding surface cutting The special material for CPVC pipes is obtained; the special material for CPVC pipes is fed into a single-screw extruder to extrude a tube blank in a molten state, and the tube blank is formed, cooled, drawn, cut and stacked to obtain enhanced power information Cable conduit. The invention utilizes the dispersion strengthening technology, and the rigid particle organosilicon spherical micropowder is used as the second phase, and the fine dispersed particles are evenly distributed in the CPVC phase to produce a strengthening effect and improve the comprehensive performance of the pipe.

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...
