Self-migration rust inhibitor and its preparation method

Abstract

The invention relates to a self-migration rust inhibitor and its preparation method. The self-migration rust inhibitor, which is a novel rust inhibitor product developed by the inventor, has very strong penetration and migration capability, can migrate from the surface layer of asphalt concretes to the surface of steel bars inside cement concretes, and has remarkable rust-resistant effect. The main components of the self-migration rust inhibitor are sodium molybdate, diethylenetriamine and the like. The rust inhibitor for steel bars has no adverse impact on concrete properties, has high-efficient steel bar rust-resistant performance, and can be widely applied in new reinforced concrete structures of sea port engineering, coastal buildings, civil buildings and the like. By the usage of the self-migration rust inhibitor, the service life of steel bars can be substantially raised, the maintenance period of roads and bridges can be prolonged, and the engineering cost can be reduced.

Description

Technical field

[0001] The invention relates to a material for a self-migrating rust inhibitor and a preparation method thereof. The self-migrating rust inhibitor produced by the process has better anti-rust and anti-corrosion effects on steel bars. Background technique

[0002] Since the founding of New China, especially in the 30 years since the reform and opening up, my country's economic construction has made great progress and achieved brilliant achievements that have attracted worldwide attention. Driven by economic construction, my country's highway construction and highway and bridge construction have achieved corresponding rapid development. When the People's Republic of my country was founded, the total mileage of highways in China was only 80,700 kilometers, but as of 2008, the total mileage of highways in my country reached 3.58 million kilometers, of which the total mileage of expressways reached 60,300 kilometers, the total mileage of expressways ranked first i...
