Water-based flash-rust inhibitor and application thereof

Abstract

The invention provides a water-based flash-rust inhibitor and application thereof. The water-based flash-rust inhibitor is prepared from, by weight, 2-10 parts of organic amine of lone pair electrons, 2-8 parts of an inorganic salt type corrosion inhibitor and 1-20 parts of a flash-rust inhibitor and further contains 15-30 parts of strontium chromate. The water-based flash-rust inhibitor serves as the flash-rust inhibitor to be applied to water-based paint. The water-based flash-rust inhibitor has an excellent flash-rust inhibiting effect, can still guarantee that no flash-rust phenomenon is produced in the construction process of the water-based paint in extreme construction environments, such as a low-temperature and high-humidity environment and a high-temperature and low-humidity environment and is good and stable in flash-rust inhibiting effect. The water-based flash-rust inhibitor is especially applied to water-based acrylic paint or water-based alkyd paint. The water-based paint added with the water-based flash-rust inhibitor is coated on a metal base material during construction, has a very good flash-rust inhibiting effect, and especially for steel parts, particularly the steel parts subjected to submerged-arc welding, has a very good flash-rust inhibiting effect.

Description

technical field [0001] The invention relates to the technical field of anti-flash rust of water-based paints, in particular to a water-based flash rust inhibitor and application thereof. Background technique [0002] Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. The paint film is plump, crystal clear, and flexible, and has the characteristics of water resistance, wear resistance, aging resistance, yellowing resistance, dry block, and convenient use. It can be used on various materials such as wood, metal, plastic, glass, and building surfaces. However, when the water-based paint is applied to the metal substrate, rust spots appear during the drying process, that is, flash rust occurs, which affects its application on the metal substrate to a certain extent. Therefore, flash rust inhibitors for water-based paints have been developed to improve the quality of water-based paint films. [0003] According to the current resear...

AI Technical Summary

Problems solved by technology

[0003] According to the current research status, the causes of flash rust in the construction process of water-based paint are complex and diverse, and there is no conclusion. As a result, most of the research and development of existing flash rust inhibitors start from the one-sided flash rust mechanism, and cannot effectively solve the flash rust fundamentally. question

Moreover, the flash rust inhibition effect of the existing flash rust inhibitors is greatly affected by the construction environment. With the change of the construction environment, the flash rust inhibition effect is different.
