Embodiment 1

[0031] A water-based nano-universal fat-free color paste, which consists of two parts: the synthesis of a dispersant and the preparation of a nano-universal color paste;

[0032] The dispersant is prepared from the raw materials in parts by mass shown in Table 1: Table 1: The specific material ratio of the dispersant

[0033]

[0034] Described nano universal color paste is prepared from the raw materials of the mass parts shown in table 2:

[0035] Table 2

[0036]

[0037] The preparation method comprises the steps of:

[0038] (1) Dissolve hydrophobic monomers, hydrophilic monomers, and functional monomers in 80% environmentally friendly solvents to form a monomer mixture, add 20% of the volume of the monomer mixture to the reactor, stir and heat up At 60°C, use two constant pressure separatory funnels to add the initiator solution (the initiator is dissolved in the remaining 20% ​​environmentally friendly solvent) and the remaining monomer mixture dropwise. After 2...

Abstract

The invention discloses a waterborne nanometer universal fat-free colorant and a preparation method thereof. The colorant is prepared from a dispersing agent and a nanometer universal colorant, wherein the dispersing agent is prepared from a hydrophobic monomer, a hydrophilic monomer, a functional monomer, an initiator and an environment-friendly solvent; the nanometer universal colorant is prepared from a toner, a dispersing agent, a humectant, an defoaming agent, an anti-settling agent, a sterilizing agent and deionized water. The dispersing agent is suitable for various waterborne fat-free colorants, particularly for pigments which are difficult to disperse such as quinacridone; the prepared colorant has high stability, is of nano-grade particle size, has efficient dispersing and anti-flocculating effects, low viscosity and high storage stability, and can be widely applied to waterborne wood lacquer, waterborne metal painting, automobile electrophoretic paint, waterborne plastic colored paint, waterborne textile printing, waterborne screen printing ink and the like.

Description

technical field [0001] The invention belongs to the technical field of fine chemical coatings, and in particular relates to a preparation method of water-based nano universal fat-free color paste. Background technique [0002] According to the different solvents used, the color paste is divided into water-based color paste, oil-based color paste, water-oil universal color paste, etc. With the improvement of water-based environmental protection awareness, water-based color paste is more and more popularized by people. Water-based color paste is used for coloring, and its application fields are very broad, including paint, leather, printing, paper, latex, textile and other industries. At present, the main service target is the paint industry. Excellent water-based colorant must have good compatibility with water-based polymer latex, uniform texture, no cross-linking agent and APE (alkylphenol polyglycol ether) solvent, and the finished colorant should have strong coloring powe...
