Preparation method of waterborne fluorosilicon resin anticorrosive paint

Abstract

The invention relates to a preparation method of waterborne fluorosilicon resin anticorrosive paint. The method comprises the following steps that (1) waterborne silicon resin emulsion, waterborne organosilicone modified acrylic resin emulsion and waterborne fluorosilicon resin emulsion are uniformly mixed to prepare a resin base body; (2) aluminum oxide powder, zinc oxide powder, rutile titaniumdioxide, mica powder, silicon micro powder and hollow glass microbeads are added into a high-speed stirring machine; the mixture is stirred and mixed into a functional filler in the high-speed stirring machine for use; (3) a certain quantity of resin base bodies, functional filling materials and diluents are fully stirred by the high-speed stirring machine and are then prepared into the waterbornefluorosilicon resin anti-corrosion paint with good dispersion. The product prepared by the method has the characteristics of green effect, no toxicity, environment-friendly effect, temperature resistance, anticorrosion, excellent mechanical property and the like. The preparation process is simple and convenient; the product can be widely applied to industries of petrochemical engineering, machinery and building and the like.

Description

technical field [0001] The invention relates to a preparation method of a water-based fluorosilicone resin anticorrosion coating, which belongs to the technical field of functional resin-based composite materials. Background technique [0002] During the process of manufacturing, construction, drying and curing of coatings, the volatile organic compounds emitted into the air are one of the important environmental pollutants and seriously threaten human health. At present, the world's coatings are developing in the direction of low pollution and pollution-free. Environmentally friendly coatings such as water-based, powderized, solvent-free, high-solid and radiation-cured coatings account for more than 70% of all coatings. In the coatings industry, the output of anti-corrosion coatings is the second largest type of coatings after architectural coatings. In recent years, affected by factors such as petroleum resources and environmental protection regulations on volatile organi...

Problems solved by technology

[0003] At present, the performance of domestically developed water-based anti-corrosion coatings is still lower than that of similar solvent-based anti-corrosion coatings, and there are still application defects that need to be overcome, such as poor water and corrosion resistance and high construction requirements. Second, the automotive topcoat has not yet been water-based, and related products have been sold abroad. At present, the water-based automotive refinish paint market is almost occupied by foreign products; in the petrochemical field, the anti-corrosion treatment of equipment is particularly important.

Anti-corrosion materials are required to have various characteristics such as heavy-duty anti-corrosion, high temperature resistance, and penetration resistance, as well as flexibility, resistance to sudden temperature changes, resistance to sudden stress changes, and bonding performance under high temperature. It is difficult to use traditional anti-corrosion coatings Meet the harsh working environment
