specific Embodiment approach 1

[0021] Specific embodiment one: the present invention is used for reinforced concrete structure in various Cl - Concentration and CO 2 Composite rust inhibitor for rust and corrosion protection of steel bars in the environment, organic rust inhibitor and inorganic nano-diameter amphibole fiber are compounded, the mass ratio is 1.0:2.0, and the organic component and mass ratio are: organic Phosphates (ATMP): benzotriazoles (BTA) = 1.0: 0.8, the content of the anionic dispersant is 0.7-1% of the mass of the nanometer-diameter amphibole fiber. The specific preparation method is as follows: first, weigh the organic rust inhibitor, anionic dispersant and inorganic nano-diameter amphibole fiber according to the proportion, put the three into a high-speed mixer for homogenization treatment to obtain the product. The homogenization treatment adopts a stirring speed of 4800 rpm, and the stirring time is 10-20 minutes.

specific Embodiment approach 2

[0022] Embodiment 2: TTA is used to replace BTA in Embodiment 1.

specific Embodiment approach 3

[0023] Embodiment 3: The BTA in Embodiment 1 is replaced by MBT.

Abstract

The invention relates to an organic composite nano-diameter amphibole fiber reinforced concrete corrosion inhibitor, and a preparation method and application thereof. The corrosion inhibitor is obtained by the steps of stirring an organic corrosion inhibitor and inorganic nano-diameter amphibole fibers in high speed, and homogenizing; the mass ratio of the organic corrosion inhibitor to the inorganic nano-diameter amphibole fibers is (1-1.5):(2.0-2.5); the invention solves the problem of low penetration resistance capacity of concrete in the prior art; and a comparison experiment result showsthat the organic composite nano-diameter amphibole fiber reinforced concrete corrosion inhibitor has rust resistance capacity under the conditions of choride ions and carbonization, improves the corrosion limit content of reinforcing steel bars, the anti-permeability capacity of a reinforced concrete protection layer, and the performance of an interfacial zone of concrete and reinforcing steel bars, and ensures that the reinforced concrete has high durability and long engineering service life, and various electrochemistry parameters completely meet the rust and corrosion resistance requirements of reinforced steel bars in the reinforced concrete.

Description

technical field [0001] The invention relates to an organic composite nano-diameter amphibole fiber reinforced concrete rust inhibitor, a preparation method and an application thereof. Background technique [0002] Reinforced concrete structure is the most important structural form in national infrastructure construction, and is widely used in various fields such as transportation, water conservancy, industry, agriculture, and national defense. However, due to the deterioration of the service performance of the concrete structure due to the corrosion of the steel bar, the service life of the project cannot meet the design requirements and the premature failure has become a major disaster and a major scientific and technological problem in the civil engineering field. has become a worldwide problem. Among the many factors affecting the durability of concrete, steel corrosion is ranked first. [0003] Corrosion of steel bars in concrete is mainly an electrochemical reaction, ...
