A kind of ultra-low voc water-based metal effect plastic paint and preparation method thereof

Abstract

The invention discloses ultralow VOC (Volatile Organic Compound) plastic paint with a waterborne metal effect. The ultralow VOC plastic paint with the waterborne metal effect is prepared by mixing the following raw materials in percentage by weight: 6-12% of all-solid type waterborne aluminum pigment, 30-35% of deionized water, 47.6-58.5% of waterborne emulsion, 1.6-2% of thickening agent, 0.4-0.5% of organic alkali, 2.5-3% of diester and 0.4-0.5% of wetting agent, wherein the content of volatile organic compound in the all-solid type waterborne aluminum pigment is lower than 1000ppm. The invention also discloses a preparation method of the ultralow VOC plastic paint with the waterborne metal effect. The ultralow VOC plastic paint with the waterborne metal effect prepared by the preparation method disclosed by the invention has the advantages of nearly zero content of VOC, environmental protection, high metallic appearance, strong covering power and good adhesiveness, and can be applicable to automobile accessories, motorcycles, household appliances, computers, electromobiles, dust collectors, mobile phones, electric tools, toys and the like.

Description

technical field [0001] The invention relates to a water-based metal effect plastic paint, in particular to an ultra-low VOC water-based metal effect plastic paint and a preparation method thereof. Background technique [0002] Volatile organic compounds (VOCs) have a huge impact on human health and have a huge impact on the environment. Today, with people's increasing awareness of environmental protection, non-toxic, odorless and low-VOC or even "zero VOC" environmentally friendly coatings are becoming more and more popular. Low-VOC coatings refer to coating products with a VOC content (mass concentration) below 30g / L "Zero VOC" paint is a paint with a VOC content of less than 10g / L (according to the US VOC test standard EPA Methods 24). At present, water-based metal effect plastic paints have a certain amount of VOC, the main source is the organic solvent contained in the metal pigment, such as isopropyl alcohol (IPA), ethylene glycol butyl ether (EB), propylene glycol met...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the technical problem of the high VOC content of the existing water-based metal effect plastic paint, the present invention provides an ultra-low VOC water-based metal with a VOC content close to zero, which is very friendly to the environment, has a high metallic feel, strong hiding power, and good adhesion.
