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

[0013] A preparation method of polyvinyl chloride pipe, comprising the following

[0014] step:

[0015] (1) Take each raw material by the weight g of the following composition raw materials:

[0016]

[0017] (2) Pour all raw materials except titanium dioxide and CPE into a stirring tank below 38°C and stir and mix at a speed of 55 rpm for 1 hour, then put it into a twin-screw extruder, knead at 150°C for 10 minutes, Mixing and granulation, the temperature is controlled at 160°C, and the finished product is obtained after the molding process;

[0018] The preparation method of the modified diamond powder is: calcining 10g of diamond powder at 550°C for 5 hours, adding 20g of attapulgite, 4g of iron powder, 2g of trioctyl trimellitate, 0.5g of glycerin, 0.5g of di Stir the methyl silicone oil at 40°C for 17 minutes, take it out, add 2g of aluminum hydroxide into an appropriate amount of water and grind evenly, add 2g of antioxidant 1076, 0.2g of graphene, stir evenly, and...

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 preparation method of 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 kind of preparation method of polyvinyl chloride pipe. [0004] The above purpose is achieved through the following schemes: [0005] A preparation method of polyvinyl chloride pipe, chara...
