AI Technical Summary

Problems solved by technology

During the high-temperature baking process of cathodic electrophoretic coatings, due to the enhanced fluidity of the paint film and the influence of surface tension, the coating film on the edges, especially the sharp edges, is thin, which in turn causes the corrosion resistance of these parts to decline.

Embodiment 1

[0096] 1. Preparation method

[0097] The electrophoretic coating is prepared by the method of the embodiment of the present invention, specifically as follows:

[0098] (1) Weigh 300g amine modified epoxy resin, 40g diethylene glycol butyl ether, 30g n-butanol, 40g neutralizer, 40g emulsifier, 380g pure water, 100g kaolin and 100g pigment.

[0099] (2) Add diethylene glycol butyl ether, n-butanol, neutralizer, emulsifier and water to the amine modified epoxy resin in sequence, and stir for 15 minutes for each raw material, then add kaolin and pigment dispersion 50 Minutes to obtain the dispersed color paste.

[0100] (3) Grind the dispersed color paste with a sand mill to obtain a dispersed and ground color paste. The fineness of the dispersed and ground color paste is not greater than 15 μm.

[0101] (4) Weigh 350g amine modified epoxy resin, 100g closed MDI curing agent, 50g emulsifier, 30g neutralizer and 470g pure water.

[0102] (5) Add closed MDI curing agent, emulsifier and neut...

Abstract

The invention discloses an electrophoresis coating material, a preparation method and applications thereof, wherein the electrophoresis coating material comprises, by mass, 10-50 parts of color paste, 10-60 parts of an emulsion; 20-50 parts of water, and 0.05-5 parts of highly polymerized microgel. According to the present invention, the electrophoresis coating material prepared by using the highly polymerized microgel, the color paste, the emulsion and the water as the components according to a certain ratio has advantages of strong corner covering ability, good anticorrosive performance at the sharp edge position, good glossiness, good impact resistance, good curability, and good flexibility.

Description

Technical field [0001] The present invention relates to the field of chemical engineering, in particular to electrophoretic coatings and preparation methods and applications thereof, and more specifically to electrophoretic coatings, methods and devices for preparing electrophoretic coatings. Background technique [0002] Since the advent of cathodic electrophoretic coatings, both the coating itself and the coating application technology have made a lot of progress. Many products and new application technologies have been introduced. So far, almost 100% of the automotive primers have been used in cathodic electrophoretic coatings. [0003] Electrophoretic coating is the first water-based coating developed. Its main characteristics are high coating efficiency, economy, safety, low pollution, and convenient for automated mass production. After decades of development, the products are constantly updated and updated. The latest cathodic electrophoretic coatings require higher swimming ...
