Abstract

The invention discloses metallic paint and a preparation method thereof and relates to the technical field of chemical industry. The metallic paint comprises the following components: 45-55 percent of hydroxylated acrylic resin, 1-1.5 percent of sodium octyl sulfate, 12-15 percent of dibutyl maleate, 12-15 percent of sodium hydroxide, 4-7 percent of copper sulfate, 4-6 percent of copper powder, 0.3-0.5 percent of a modified polysiloxane flatting agent and water in balance amount. The metallic paint is good in levelling property, non-poisonous, free of abnormal taste and is suitable for surface repairing of automobiles, motorcycles and the like.

Description

Technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a metallic paint and a preparation method thereof. Background technique [0002] With the continuous advancement of industrialization and urbanization, environmental quality has an increasingly important impact on people’s physical and mental health. Therefore, environmental quality has received more and more attention. my country has also strengthened the monitoring and management of air quality. The existence of some materials that meet the standards and other reasons, environmental pollution still threatens people's health. [0003] At present, in the automotive and motorcycle refinishing paint market, the use of metallic paint is relatively widespread, because metallic paint is a product that is easy to use and fast-drying, and has been widely accepted by users. The existing metallic paints generally contain toxic substances such as formaldehyde and phenol, which are ha...
