Water-based electroplating sealing gloss oil and preparation method thereof

Abstract

The invention discloses water-based electroplating sealing gloss oil. The gloss oil comprises raw materials in percentage by mass as follows: 30%-40% of water-based thermosetting acrylic resin, 5%-8% of water-based methylated amino resin, 2%-4% of a salt-fog-resistant additive, 0.3%-1% of an epoxy silane coupling agent, 0.3%-1% of a leveling agent, 0.2%-0.8% of a defoaming agent, 20%-28% of isopropyl alcohol, 5%-10% of butyl cellosolve, 15%-20% of propylene glycol monomethyl ether acetate, 1%-3% of a neutralizer and 12%-20% of deionized water. The invention further discloses a preparation method of the water-based electroplating sealing gloss oil. The water-based electroplating sealing gloss oil has the advantages of high glossiness, excellent adhesive force, high hardness, high salt fog resistance, high acetic acid resistance, high alkali resistance and high gasoline resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based electroplating sealing varnish and a preparation method thereof. Background technique [0002] As we all know, China is a big manufacturing, processing and exporting country. With the rapid development of the national economy, the waste gas produced by industrial production has become more and more serious to the environment. Many products are exported abroad, and the European Union has strict requirements on the chemical coatings used on imported products. Therefore, there are many small and medium-sized coating companies that are sighing at the electroplating varnish market. Due to the gradual depletion of petroleum resources, most of the raw materials used in the production of coatings are petroleum derivatives, so the raw materials are increasing year by year. Chemical companies are facing Due to severe cost pressure, our company firmly grasped the pulse of th...

Problems solved by technology

[0003] In today's world, water-based coatings in developed countries in Europe and the United States are comparable to traditional solvent-based coatings in terms of variety matching and coating quality. Its VOC emissions are small, and its emissions are about one-third of solvent-based paints. The development of water-based paint technology is not solvent-based paint technology. If my country does not develop water-based paint, international exchanges and cooperation in coating technology will become more and more difficult in the future, which is not conducive to the improvement of my country's coating technology level.
