Description
Technical Field
The invention relates to the technical field of pipe preparation, in particular to an impact-resistant PE double-wall corrugated pipe and a preparation method thereof.
Background
The double-wall corrugated polyethylene pipe has light weight, low cost, acid and alkali resistance, high corrosion resistance, low resistance, high compression strength and other advantages, and may be used widely in water supply, drainage, pollution discharge, exhaust and other fields.
A PP double-wall corrugated pipe and a preparation method thereof are disclosed in a patent document with the application number of 'CN 201811242177.7' and the name of 'a PP double-wall corrugated pipe and a preparation method thereof', and belong to the field of corrugated pipes. The PP double-wall corrugated pipe comprises the following raw materials in parts by weight: 90-110 parts of PPR particles, 23-27 parts of 001 polyethylene powder, 4-6 parts of 7042 polyethylene powder, 45-55 parts of heavy calcium carbonate, 2-4 parts of stearic acid and 7-9 parts of color master batch; the inner wall and the outer wall of the double-wall corrugated pipe are both made of the raw materials in parts by weight; the raw materials of the inner wall of the double-wall corrugated pipe also comprise 2-4 parts of carbon fiber and 3-5 parts of mica; the raw material of the outer wall of the double-wall corrugated pipe also comprises 2-4 parts of molybdenum disulfide. The PP double-wall corrugated pipe disclosed in the above patent documents has relatively insufficient impact resistance per se although it has good wear resistance and corrosion resistance, which affects the quality of the PE double-wall corrugated pipe to some extent. Moreover, the anti-aging performance of the rubber is relatively poor, and the service life of the rubber is shortened to a certain extent.
Based on the above, the invention provides an impact-resistant PE double-wall corrugated pipe and a preparation method thereof, so as to solve the problems.
Disclosure of Invention
The invention aims to provide an impact-resistant PE double-wall corrugated pipe and a preparation method thereof.
In order to achieve the purpose, the invention provides the following technical scheme:
the impact-resistant PE double-wall corrugated pipe comprises an inner pipe and a corrugated outer pipe which is attached to the outer wall of the inner pipe, wherein the PE double-wall corrugated pipe is made of the following raw materials in parts by weight: 60-90 parts of high-density polyethylene, 35-60 parts of ultra-high molecular weight polyethylene, 55-75 parts of POE resin, 15-22 parts of toughening master batch, 8-20 parts of mica powder, 3-7 parts of nano titanium dioxide, 3-6 parts of vinyl trimethoxy silane, 2-6 parts of carbon nano tube, 5-8 parts of zinc stearate, 3-5 parts of erucamide, 6-12 parts of toughening aid, 5-8 parts of antistatic agent, 2.5-4 parts of antioxidant and 4-7 parts of carbon black master batch;
the toughening master batch is prepared from the following raw materials in parts by weight: 20 to 35 portions of high density polyethylene, 12 to 18 portions of linear low density polyethylene, 0.3 to 0.6 portion of polyethylene nucleating agent HPN-20E, 0.4 to 0.8 portion of PE polyethylene nucleating agent WXH-C201, 2.5 to 6 portions of calcium carbonate and 1.5 to 3 portions of talcum powder.
Further, the preparation method of the toughening auxiliary agent comprises the following steps:
