Problems solved by technology

[0009] In order to solve the problem of slow drying speed of the color repairing agent, the present invention introduces a low boiling point solvent methanol, which has a fast volatilization speed and greatly improves the drying speed of the color repairing agent. Adding triethylamine can effectively stabilize the pH value of the system and increase its stability Wait

Abstract

The invention relates to a quick-drying water-based general-purpose modified water-based alkyd resin color repair agent, which consists of: 10.0-20.0 parts of modified water-based alkyd resin, 2.0-30.0 parts of water-based special color essence, 0.1-0.4 parts of defoaming agent, 0.1-0.5 parts of dispersant, 50.0-80.0 parts of methanol, 0.5-3.0 parts of triethylamine, 10.0-25.0 parts of deionized water; wherein, the modified water-based alkyd resin is made of vegetable oil , organic acid anhydride, 2‑hydroxyethylamine, anisaldehyde, polyol, polybasic acid, neopentyl glycol hydroxypivalate, monobutyl itaconate, dimethylol propionic acid and neutralizing agent ; A quick-drying water-oil general-purpose modified water-based alkyd resin color repair agent prepared by the present invention does not require additional bactericides, does not precipitate during storage, has a fast drying speed, has good wettability to primers, and does not appear to bloom; When adding color essence, it will not break the emulsion, and will not produce particles and sediments; it is not only suitable for color correction of water-based paints, but also can be used for color correction of oil-based paints.

Description

Technical field [0001] The present invention relates to a modified aqueous molding agent, and more particularly to a fast-drying water-dry general-purpose modified aqueous alkyd resin molding agent and a preparation method thereof, which belongs to aqueous functional polymer technology. Background technique [0002] Water-based wood coating is the main direction of the development of the wood coating industry in the past ten years. As the state is increased to environmental investigation, "oil-to-water" is an important topic in wood coatings in recent years. However, in the implementation of "oil-to-water", the traditional fully enclosed varnish surface is very difficult, due to the slowness of the water, the solvent coating is slow, the surface tension of water is large. It causes the aqueous mold coloring unevenness, which has seriously plagued the process of full-enclosed varnish painting "oil to water". [0003] When spraying, in order to improve production efficiency, a larg...
