Problems solved by technology

[0004] Due to the direct contact between the outer wall of the steel-plastic composite pipe and the slip ring, local stress will be generated at the contact between the slip ring and the outer wall of the steel-plastic composite pipe when standing still. Currently, for the sake of beauty, the style of the curtain is more complicated and the weight is heavier. The overall strength of the outer wall of the current steel-plastic composite pipe is not high, which makes it easier to damage the outer wall of the steel-plastic composite pipe

Embodiment 1

[0056] Example 1: A material for the outer wall of a steel-plastic composite pipe, the components included and their corresponding parts by weight are shown in Table 1, and are prepared through the following steps:

[0057] S1, mix polyvinyl chloride resin, filler, stabilizer, lubricant, anti-impact additive, and colorant with each other, heat up to 90°C, and mix thoroughly to obtain a mixture;

[0058] S2, granulating the mixture obtained in step S1 at a temperature of 170° C. to obtain the outer wall material of the steel-plastic composite pipe.

[0059]Among them, the anti-impact additive is 6 parts by weight of chlorinated polyethylene and 2 parts of acrylic acid ester polymer copolymer, the particle size of acrylic acid ester polymer copolymer is 0.45 mm, and the acrylic acid ester polymer copolymer has a particle size of 0.45 mm. The viscosity of acid lipid polymer copolymer is 5.28ml / g; the Shore hardness of chlorinated polyethylene is 56SHA; the tensile strength of chl...

Embodiment 2-5

[0064] Example 2-5: A steel-plastic composite pipe outer wall material, the difference from Example 1 is that the components included and their corresponding parts by weight are shown in Table 1.

Abstract

The invention discloses a steel plastic composite pipe outer wall material and a preparation process thereof. The steel plastic composite pipe outer wall material is prepared from 100 parts of polyvinyl chloride resin and 40 to 60 parts of filling agents, 5 to 9 parts of stabilizing agents, 0.8 to 2 parts of lubricating agents, 0.1 to 0.6 part of 2,2-bis(p-hydroxyphenyl)propane, 3 to 16 parts of anti-impact auxiliary agents and 3 to 10 parts of coloring agents, wherein the stabilizing agents comprise at least one kind of materials from calcium and zinc stabilizing agents and rare earth stabilizing agents; the lubricating agents comprise at least one kind of materials from stearic acid and paraffin; the anti-impact auxiliary agents comprise at least one kind of materials from chlorinated polyethylene and acrylic ester type macromolecular copolymers. The steel plastic composite pipe outer wall prepared from the steel plastic composite pipe outer wall material has the advantages that goodintegral intensity is realized; the damage cannot easily occur.

Description

technical field [0001] The invention relates to the technical field of plastic materials, more specifically, it relates to a steel-plastic composite pipe outer wall material and a preparation process thereof. Background technique [0002] Steel-plastic composite pipes are usually pipe fittings that combine plastic pipes and metal pipes. The existing preparation methods for steel-plastic composite pipes usually use seamless steel pipes or welded steel pipes as the base pipe, and then cover the base pipe with a plastic pipe to make the plastic pipe It is an interference fit with the base pipe. [0003] Therefore, the overall requirements for the plastic pipe part are mainly reflected in its overall strength and formability. [0004] Due to the direct contact between the outer wall of the steel-plastic composite pipe and the slip ring, local stress will be generated at the contact between the slip ring and the outer wall of the steel-plastic composite pipe when standing still....
