Abstract

The invention relates to the technical field of water-based multicolor paint, in particular to a preparation method of two-in-one emulsion for multicolor paint, which comprises the following raw materials in parts by weight: 500-650 parts of deionized water, 0.1-10 part of reactive emulsifier, 0.5-10 part of anionic emulsifier, 0.1-5 part of acidic monomer, 1-12 parts of amino monomer, 1-50 partsof nitrile monomer and 1-50 parts of hydrophilic functional monomer. The invention relates to a high-temperature-resistant polyurethane adhesive which comprises the following components in parts by weight: 350-450 parts of a main monomer, 0.1-2 part of buffer salt, 0.1-10 part of an initiator, 1-15 parts of a silane coupling agent, 0.1-50 part of a pH regulator, 0.2-10 part of a defoaming agent and 0.5-10 part of a preservative. The two-in-one emulsion for the multicolor coating prepared by the invention can replace two emulsions, namely a dispersion phase emulsion and a continuous phase emulsion, required for preparing the multicolor coating, so that the problem that the compatibility of the two emulsions is unstable due to poor batch stability of the dispersion phase emulsion and the continuous phase emulsion is solved, and the stability of the multicolor coating is further ensured; The wide market prospects are realized.

Description

technical field [0001] The invention relates to the technical field of water-based colorful paints, in particular to a method for preparing a two-in-one emulsion for colorful paints. Background technique [0002] Water-based colorful paint was first proposed by John C.Zola of the United States in the late 1960s, and US3458328 disclosed a colorful paint dispersed in a water-dispersed medium containing film-forming substances and composed of a water dispersion of colored spherical particles. Water-based colorful paint is mainly used to decorate the interior and exterior walls of buildings. It has the characteristics of imitating the pattern and color of high-grade decorative materials such as natural granite and wallpaper. It can also provide pattern sizes according to the different shapes of old and new buildings and according to customer needs. Different and colorful designs and patterns achieve the perfect unity of decorative effect and functionality. Moreover, it is very ...
