Hydraulic pressure anti-rust agent for boiler auxiliary machine container products, and preparation method thereof

Abstract

The invention relates to a hydraulic pressure anti-rust agent for boiler auxiliary machine container products, and a preparation method thereof. In the prior art, the problem of the inner surface rust after hydraulic pressure tests of boiler auxiliary machine container products (such as oxygen removing devices, hydrophobic expansion devices, and the like) has not been effectively solved, seriously affects the quality of the product inner surface, and further can cause the potential threat to the safe operation of the boiler auxiliary machine container. The hydraulic pressure anti-rust agent comprises the following raw materials by weight: 10-15 parts of a methacrylic acid polymer, 0.5-1 part of dibutyl phthalate, 0.5-1 part of dicresyl phosphate, 25-28 parts of butyl acetate, 3-5 parts of butanol, 8-12 parts of acetone, and 40-50 parts of toluene. The hydraulic pressure anti-rust agent of the present invention is used as the boiler auxiliary machine container anti-rust material.

Description

Technical field: [0001] The invention relates to a hydraulic antirust agent for boiler auxiliary equipment container products and a preparation method thereof. The invention belongs to an antirust material for boiler auxiliary machine container products and an auxiliary material for nuclear power products, and solves the problems of large consumption, high cost, unsatisfactory antirust effect and the like in the prior art. Background technique: [0002] With the rapid and steady development of the national economy, the manufacturing level of my country's power plant boiler equipment has also made great progress, and the problem of anti-corrosion on the inner surface of the product has also been paid more and more attention. However, the corrosion problem of the inner surface of the boiler auxiliary equipment container products (such as deaerator, hydrophobic expander, etc.) after the hydrostatic test has not been effectively solved. This problem not only seriously affects t...

AI Technical Summary

Problems solved by technology

However, the corrosion problem of the inner surface of the boiler auxiliary equipment container products (such as deaerator, hydrophobic expander, etc.) after the hydrostatic test has not been effectively solved.

During the actual application process, it was found that there were problems such as large amount of water-based anti-rust and corrosion inhibitor, high cost, and poor anti-rust effect; at the same time, the waste liquid polluted the environment after the hydrostatic test, which did not comply with the national safety and environmental protection production policy
