Abstract

The invention discloses an environment-friendly vicat high-impact low-temperature-resistant vulcanization-pollution-resistant electric conduit and a preparation method thereof. The electric conduit is prepared from CPVC resin, HPVC resin, PVC resin, a filler, a calcium-zinc stabilizer, CPE, ABS, an anti-aging agent, an external lubricant, an internal lubricant and a pigment according to a certain proportion. The preparation method comprises the following steps: uniformly mixing the raw materials, adding the uniformly mixed raw materials into a double-screw extruder, setting the temperature of a machine barrel to be 160-200 DEG C, the temperature of a confluence core to be 150-155 DEG C, the temperature of a template to be 160-190 DEG C and the temperature of a mouth mold to be 160-190 DEG C, adding the pigment red through a stepping machine of the double-screw extruder, carrying out extrusion molding, and then carrying out cooling and shaping to obtain the environment-friendly high-vicat high-impact-resistance low-temperature-resistance vulcanization-pollution-resistance electric conduit. The electric conduit is high in vicat softening point, low in pipe ring stiffness at high temperature and good in impact resistance at low temperature. The preparation method of the electric conduit is simple, convenient to operate and low in preparation cost.

Description

technical field [0001] The invention relates to the technical field of electrical conduit preparation, in particular to an environment-friendly, high-vicat, high-impact, low-temperature, anti-vulcanization, and pollution-resistant electric conduit and a preparation method thereof. Background technique [0002] The main materials of power pipes are PVC-U, CPVC, MPP and so on. With the continuous development of the country, the expansion of urban power pipe network construction is increasing, and the demand for plastic power pipes is increasing. It can withstand high temperature without deformation; in low temperature environment, the pipe can maintain high strength and not become brittle, so as to avoid the pipe rupture caused by collision at low temperature. At the same time, with the continuous improvement of environmental protection requirements, it is required that the production of pipes does not contain heavy metals, and the pipes must also avoid sulfuration pollution ...
