preparation example Construction

[0026] The preparation method of antirust agent of the present invention is characterized in that comprising following concrete steps:

[0027] (1) Determine the dosage of each component;

[0028] (2) Add fluorocarbon resin to water and stir until it is evenly mixed. The volume ratio of fluorocarbon resin to water is 1:6-15; add silane coupling agent to water and stir until it is evenly mixed. The volume ratio of silane coupling agent to water is 1:6~15; add titanate coupling agent into water and stir well until mixed evenly, the volume ratio of titanate coupling agent to water is 1:50~100;

[0029] (3) Mix the above three solutions evenly, add water to make up volume;

[0030] (4) Add carbon black and mix well to form a suspension to obtain the rust inhibitor.

[0031] As a preference of the technical solution of the present invention, after the fluorocarbon resin, silane coupling agent and titanate coupling agent are added into water, they are placed in a constant temperat...

Embodiment 1

[0035] The antirust agent formula is: 30mL / L fluorocarbon resin, 30mL / L KH500 silane coupling agent, 2mL / L NDZ-201 titanate coupling agent, 2g / L carbon black, and the balance is water.

[0036] Add 30mL of fluorocarbon resin to 240mL of water, place in a constant temperature water bath at 70°C, and stir well until the mixture is evenly mixed into a transparent solution. Add 30mL of KH500 silane coupling agent to 400mL of water, place in a constant temperature water bath at 70°C, and stir well until the mixture is evenly mixed into a transparent solution. Add 2mL of NDZ-201 titanate coupling agent to 160mL of water, place in a constant temperature water bath at 70°C, and stir well until the mixture is uniform and a transparent solution is formed. Mix these three kinds of solutions evenly, add water to make the volume to 1L, and finally add 2g of carbon black, and mix well to form a suspension to obtain the rust inhibitor.

[0039] The antirust agent formula is: 30mL / L fluorocarbon resin, 30mL / L KH560 silane coupling agent, 2mL / L NDZ-101 titanate coupling agent, 2g / L carbon black, and the balance is water.

[0040] Add 30mL of fluorocarbon resin to 300mL of water, place in a constant temperature water bath at 70°C, and stir well until the mixture is evenly mixed into a transparent solution. Add 30mL of KH560 silane coupling agent to 450mL of water, place in a constant temperature water bath at 70°C, and stir well until the mixture is uniform and a transparent solution is formed. Add 2mL of NDZ-101 titanate coupling agent to 150mL of water, place in a constant temperature water bath at 70°C, and stir well until the mixture is uniform and a transparent solution is formed. Mix these three kinds of solutions evenly, add water to make the volume to 1L, and finally add 2g of carbon black, and mix well to form a suspension to obtain the rust inhibitor.

Abstract

The invention discloses a rust preventer and a preparation method and application thereof. The rust preventer disclosed by the invention contains 30-50mL / L of fluorocarbon resin, 30-50mL / L of silane coupling agent, 2-3mL / L of titanate coupling agent, 2-3g / L of carbon black and the balance of water. The invention further discloses the preparation method of the rust preventer and application of the water-based rust preventer in the rust prevention of hot-rolled ribbed steel bars. The rust preventer disclosed by the invention is convenient in use, good in rust prevention effect and low in cost, the condition that rusting cannot occur in an open-air environment under the conditions of being exposed to the wind, rain and sun can be maintained for 2-3 months, and the mechanical properties and welding performance of steel bars are not affected, so that the problem that the bearing capacity, durability and the like of reinforced concrete members are affected due to the fact that the existing hot-rolled ribbed steel bars severely rust is fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of steel surface treatment technology, and in particular relates to an environment-friendly high-temperature antirust agent capable of delaying the corrosion of hot-rolled ribbed steel bars in an atmospheric environment, and a preparation method and application thereof. Background technique [0002] As construction steel, hot-rolled ribbed steel has always occupied a large proportion of my country's steel production and plays a vital role in the national economy. In recent years, in order to produce low-cost high-strength steel bars, the main method adopted by major iron and steel enterprises is the water cooling process after final rolling. This process can improve the structure to a certain extent and improve the mechanical properties of steel bars, but there is a big disadvantage in this process, that is, the hot-rolled ribbed steel bars cooled by water are easy to rust during storage and transportation, ...
