Problems solved by technology

[0002] Mixing in the production of PVC pipes requires two processes of cold mixing and hot mixing. In the hot mixing stage, if the moisture content in the raw materials is inconsistent, the temperature during mixing will change accordingly. The external lubricant decomposes, the actual use effect of the auxiliary materials cannot achieve the expected purpose, and only 600 kg of raw materials can be processed each time through two mixings, the labor intensity is relatively high, and the power consumption is relatively high

Embodiment Construction

[0021] A preparation method of an energy-saving polyvinyl chloride pipe, comprising the following

[0022] step:

[0023] (1) Weigh each raw material according to the weight g of the following composition raw materials:

[0024] PVC resin 75

[0025] Calcium bicarbonate 75

[0026] Paraffin: 0.64

[0027] Titanium dioxide: 1.5

[0028] Stearic acid: 0.48

[0029] CPE: 5

[0030] Calcium zinc composite stabilizer 3.5

[0031] Modified diamond powder 4;

[0032] (2) Pour all the raw materials except titanium dioxide and CPE into the stirring tank below 38°C, stir and mix for 1 hour at a speed of 55 r / min, then put it into a twin-screw extruder, and knead it at 150°C for 10 minutes. Mixing and granulating, the temperature is controlled at 160 °C, and the finished product is obtained after the molding process;

[0033] The preparation method of the modified diamond powder is as follows: calcining 10 g of diamond powder at 550° C. for 5 hours, adding 20 g of attapulgite...

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 [0001] The invention relates to the field of polyvinyl chloride materials, in particular to a method for preparing energy-saving polyvinyl chloride pipes. Background technique [0002] Mixing in the production of PVC pipes requires two processes of cold mixing and hot mixing. In the hot mixing stage, if the moisture content in the raw materials is inconsistent, the temperature during mixing will change accordingly. The external lubricant decomposes, the actual use effect of the auxiliary materials cannot achieve the expected purpose, and only 600 kg of raw materials can be processed each time through two mixings, the labor intensity is relatively high, and the power consumption is relatively high. Contents of the invention [0003] The object of the present invention is to provide a preparation method of energy-saving polyvinyl chloride pipe. [0004] The above purpose is achieved through the following schemes: [0005] A method for preparing an energy-sa...
