Abstract

The invention relates to the technical field of coatings, and discloses a waterborne intermediate paint coating and a preparation method thereof. The waterborne intermediate paint coating is preparedfrom the component A and the component B; the component A is prepared from the following components in percentage by mass: epoxy emulsion, a dispersant, a defoamer, a coalescing agent, mica iron oxide, glass flake, fillers, barium sulfate, pigments, expanded graphite, vermiculite, silicon dioxide, an anti flash rust agent, zirconium phosphate, a base material wetting agent, a thickener and the balance of deionized water; the component B is prepared from the following components in percentage by mass: a curing agent and the balance of a coalescing agent; the mass ratio of the component A to thecomponent B is (4-8) to 1. The waterborne intermediate paint coating is good in flow resistance, stable in storage performance and anticorrosion performance, and good in adhesion, impact resistance,flame retardancy and flexibility performance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based intermediate paint coating and a preparation method thereof. Background technique [0002] With the deteriorating environment, in the use of steel in our country, the phenomenon of late rust and corrosion is becoming more and more serious year by year, resulting in a serious waste of steel resources in our country. Therefore, the requirements for post-coating of steel are becoming more and more important. During the installation process, primers, intermediate paints and topcoats are generally required to be used together to achieve a good anti-corrosion effect. The use of primers, intermediate paints, and topcoats for anticorrosion has the same service life. The economy is better and the cost is lower. [0003] The functions of the intermediate paint are: increase the thickness of the paint film, improve the durability and service life of the coating, and have goo...
