Aqueous woodenware statin topcoat and preparation method thereof

Abstract

The invention discloses an aqueous woodenware statin topcoat and a preparation method thereof. The aqueous woodenware statin topcoat comprises, by mass, 85-97% of an aqueous color remanding base material and 3-15% of a high-concentration aqueous color concentrate. The aqueous color remanding base material comprises, by weight, 5-16% of an aqueous core-shell acrylic emulsion, 70-85% of industrial alcohol, 1-12% of deionized water and 1-8% of an environmentally-friendly cosolvent. The paint has the advantages of fast drying speed, good stability, uniform color remanding effect, uniform color, and convenience in construction.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based wood surface repair paint and a preparation method thereof. Background technique [0002] In recent years, with the continuous improvement of people's requirements for living conditions and living environment, water-based wood paint has achieved rapid development. However, there is still a certain gap in the application of water-based wood coatings compared with solvent-based coatings, especially in the transparent coating of water-based wood coatings, surface color correction is a difficult problem in factory production. [0003] There are roughly two types of traditional surface repairing methods: 1. Color repairing water, that is, adding water-based color essence to some alcohol solvents for color repairing. This kind of color repairing and coloring is easy, but because there is no film-forming substance in the color repairing water , color control is more difficult, and...

Problems solved by technology

[0003] There are roughly two types of traditional surface repairing methods: 1. Color repairing water, that is, adding water-based color essence to some alcohol solvents for color repairing. This kind of color repairing and coloring is easy, but because there is no film-forming substance in the color repairing water , color control is more difficult, and it is prone to bottoming after spraying topcoat; 2. Water-based color repair paint containing emulsion is generally made of water-based color repair base material from water-based emulsion, additives, solvents and water. Add water-based color essence for color

This kind of water-based color repair paint has a slow drying speed. Spraying water-based topcoat immediately after spraying water-based color repair paint in southern construction is prone to blooming, especially under high temperature and high humidity conditions, the construction interval is longer, reducing the Construction efficiency, and the concentration of the existing water-based color essence is low, the amount of addition is relatively large, and some even add 30% water-based color essence, which makes the construction operability poor and the price is high

[0004] At present, there is a lack of a water-based wood surface repair paint with fast drying speed, good stability, and no influence on construction under high temperature and high humidity conditions and its preparation method
