Water-based coloring base material and preparation method thereof

Abstract

The invention discloses a water-based coloring base material and a preparation method thereof. The water-based coloring base material comprises the following raw materials in percentage by weight: 30-40% of water-base resin 1, 20-30% of water-base resin 2, 20-30% of water, 1-1.5% of sensitiser, 1-2% of thickener, 5-8% of alcohol ether solvent, 0.1-0.5% of defoamer, and 0.5-1% of PH value regulator. The water-based coloring base material has the advantages of high permeability, high coloring effect, environmental protection and no odor, good adhesion, convenience in construction and the like, besides the basic properties of both of a UV (Ultraviolet) water-based coloring base material and a purely water-based coloring base material. In addition, the water-based coloring base material can be directly matched with a water-based pigment and a water-based dye, and diluted by water to obtain appropriate color concentration, thereby achieving perfect ornamental effect and meeting the requirements of customers.

Description

Technical field [0001] The invention relates to an aqueous coloring base material and a preparation method. Background technique [0002] At present, traditional wood coloring base materials are roughly water-based UV coloring and pure water-based coloring. The main component of the water-based UV coloring base material is a UV-drying water-based polyurethane resin. Due to its special molecular structure, it is easy to produce sticky non-drying, coloring and accumulation, and thickening during construction, which affect the coloring of wood products. The effect is not up to the customer's requirements. However, the traditional pure water-based coloring base material has a relatively fast drying and film forming process, resulting in stiff coloring, poor permeability, and weak layering. At the same time, there is no cross-linking reaction group for the upper UV system, and the entire paint film is easy to fall off , The adhesion is poor, and it also fails to meet customer r...

AI Technical Summary

Problems solved by technology

The main component of water-based UV coloring base material is water-based polyurethane resin that can be UV-dried. Due to its special molecular structure, it is easy to cause stickiness and non-drying during the film forming process, easy accumulation of coloring, and thickening during construction, which will affect the coloring of wood products. The effect does not meet the customer's requirements

However, the traditional pure water-based coloring base material dries and forms a film relatively quickly, resulting in hard coloring, poor permeability, and weak layering. At the same time, there is no cross-linking reactive group for the upper UV system, and the entire paint film is easy to fall off. , the adhesion is not good, and it also fails to meet customer requirements.
