Problems solved by technology

Conventional anti-corrosion methods for concrete pipelines generally use lining PVC or rubber materials. Due to the problems that PVC and rubber materials are not tightly connected with concrete and are easy to age, after a period of operation, the lining materials will fall off, thus making the pipeline lose its anti-corrosion performance; There are also concrete pipelines that use epoxy anti-corrosion coatings (such as epoxy asphalt, etc.). Since the epoxy coating has no air permeability, the concrete surface of the component must be dry during construction, otherwise the coating is easy to bubble and peel off. anticorrosion failure

Abstract

The invention provides a corrosion-resisting pipe component and a preparation method thereof, and relates to the technical field of concrete pipes. The corrosion-resisting pipe component is prepared from the following raw materials: flyash, silica fume, kaolin, talcum powder, ethylene bis stearamide, triethanolamine, calcium chloride, a defoaming agent, fiber materials, a retarder, a water reducing agent and water. The corrosion-resisting pipe component disclosed by the invention has the advantages of better durability and sealing property, good stability, high corrosion resistance and high anti-seepage ability; mechanical properties of the concrete pipe component are ensured; in addition, the strength of the concrete pipe component is enhanced and the corrosion resistance of the concretepipe is improved due to the introduction of the silica fume, the talcum powder and fiber materials. Besides, by the addition of the ethylene bis stearamide, the triethanolamine, the defoaming agent, the retarder and the water reducing agent, acid resistance, alkali resistance, corrosion resistance and anti-aging properties of the concrete pipe component are enhanced.

Description

technical field [0001] The invention relates to the technical field of concrete pipes, in particular to a corrosion-resistant pipe member and a preparation method thereof. Background technique [0002] Concrete drainage pipes laid underground for a long time are generally used well, and the cost of the pipe itself is very low. However, due to the heavy weight of the pipe, it is difficult to transport and install, and the requirements for the foundation are relatively high (concrete foundation is often used), so the overall cost is not high. Low, and when there are corrosive media inside or outside, corrosion damage will occur, resulting in a decrease in structural strength, failing to meet the requirements of the service life, resulting in waste of energy and resources. In recent years, due to the lack of tightness of the interface of the drainage pipeline, the ground subsidence accidents caused by the leakage of rainwater and sewage affecting the foundation have gradually i...
