Problems solved by technology

Vinyl ester coatings are free radical curing, and the curing time is short, so the overcoating time is generally strictly limited, and the time is relatively short, which is easy to cause the coating to fall off
Using manual operations such as scraping and coating on the one hand, the cons

Abstract

The invention provides a low-viscosity large-film-thickness vinyl ester paint with a repeated coating function and a preparation method thereof. The low-viscosity large-film-thickness vinyl ester paint with the repeated coating function comprises vinyl ester resin, a flaky filler, a sulfur-containing modified compound, a phosphate, a composite functional rheological agent and other additives. According to the low-viscosity large-film-thickness vinyl ester paint with the repeated coating function, by means of mutual cooperation of the flaky filler, the phosphate and the sulfur-containing modified compound, the adhesive force between a paint film and a base material is enhanced, and the corrosion resistance of the paint film is effectively improved. Moreover, the components also comprise thecomposite functional rheological agent, and the composite functional rheological agent component comprises fumed silica, a modified carboxylic acid amide solution, a modified urea solution and a coupling agent so that the thixotropic property of the paint can be effectively improved; the influence on the viscosity of the paint is relatively small, the paint can be used for spraying construction,and the service life of the paint film is prolonged, so that the paint meets the requirements for low viscosity, spraying and large film thickness, the single dry film thickness can reach 1000-1500 micron, time and labor are saved, and energy and investment are saved.

Description

technical field [0001] The invention relates to the technical field of vinyl ester coatings, in particular to a recoatable vinyl ester coating with low viscosity and high film thickness and a preparation method thereof. Background technique [0002] Vinyl ester coating itself has strong chemical resistance and shielding properties, and can be applied to various chemical-resistant media and anti-corrosion applications in various projects. However, due to the disadvantages of vinyl ester coatings such as poor adhesion to substrates, high viscosity of coatings, harsh requirements for recoating performance, and difficulty in spraying, vinyl ester coatings are hindered in the use of vinyl ester coatings during actual use. [0003] Chinese Patent No. ZL 200710172753.0, date of publication September 10, 2008, the title of the invention patent "Preparation Process of Two-Component Epoxy Vinyl Ester Coating" uses modified urea solution or polyethylene wax paste, and the viscosity of ...
