Abstract
The invention discloses a preparation method for an energy-saving polyvinyl chloride tubular product. The preparation method comprises the steps of pouring all raw materials except for titanium dioxide and CPE into a stirring kettle, mixing the raw materials at the rotating speed of 55-70r/m for 1 hour, then putting the raw materials into a double-screw extruder, kneading the raw materials under the temperature of 140-150 DEG C for 8-10 minutes, adding the rest of the raw materials according to the weight parts, performing mixing and granulation, controlling the temperature at 150-160 DEG C, and performing a forming technology to obtain a finished product. The tubular product prepared by the preparation method disclosed by the invention is stable in quality and high in strength and has a smooth surface. The preparation technology is energy-saving, economical and environment-friendly.
Description
Technical field
The present invention relates to pvc material field, is exactly a kind of preparation method of energy-saving polyvinyl chloride tubing.
Background technology
Batch mixing in the production of pvc pipe material, will be by cold mixed and mixed two techniques of heat, in the mixed stage of heat, as inconsistent in water content in raw material, the temperature when mixed will change thereupon, decompose because excess Temperature impels inside and outside lubricant, the practical effect of auxiliary material cannot accomplish the end in view, and mix and can only process 600 kilograms of raw materials at every turn by twice, labour intensity is larger, and power consumption is higher.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of energy-saving polyvinyl chloride tubing.
Above-mentioned purpose realizes by following scheme:
A preparation method for energy-saving polyvinyl chloride tubing, is characterized in that:
