Problems solved by technology

[0002] Color correction agents are widely used in furniture and other decorations, but currently a large amount of ethanol is added to color correction agents on the market, which is prone to fire during transportation and use in furniture factories, and the volatilization of ethanol into the air has certain harmful effects on the human body. Harm, and pollute the air at the same time, especially for places such as furniture factories and high-end hotel furniture with high environmental protection requirements
Such color repairing products greatly increase potential safety hazards and endanger human health. Therefore, it is necessary to develop a safe and environmentally friendly color repairing agent product

preparation example Construction

[0026] Another aspect of the present invention also provides a preparation method of the color-correcting composition, comprising the steps of: (1) stirring the water-based polyurethane resin at a stirring speed of 400-600 r / min.

[0027] In step (1), the water-based polyurethane resin is added into a container, such as a reaction kettle, and the stirring is started. The stirring is, for example, 400r / min, 500r / min, 600r / min.

[0028] The preparation method of the color-correcting composition of the present invention also includes the step of: (2) adding the cosolvent, the wetting agent, the defoamer, the bactericide and the water, and continuing to stir The color correcting composition is prepared.

[0029] In step (2), the co-solvent, the wetting agent, the defoamer, the bactericide and the water are slowly added in sequence.

[0030] The present invention also provides a water-based color-correcting agent comprising the above-mentioned color-correcting composition. Based...

Embodiment 1

[0033] Weigh 70g of water-based polyurethane and add it to the reaction kettle, turn on the stirring speed of 400r / min, and stir; to the reaction kettle, add 3g DPNB, 0.8g Digao 4100, 0.5g Digao 902W, 0.1g of the sterilization agent and 25.6g of the remaining water, and continued to stir for 30 minutes to prepare a color-correcting composition 1. The specific ratio and test performance are shown in Table 1.

Embodiment 2

[0035] Weigh 75g of water-based polyurethane and add it to the reaction kettle, turn on the stirring speed of 400r / min, and stir; in the reaction kettle, add 3g DPM, 0.8g Digao 4100, 0.5g Digao 902W, 0.1g of the sterilizing agent and 20.6g of remaining water, and continued to stir for 30 minutes to prepare color-correcting composition 2. See Table 1 for the specific ratio and test performance.

Abstract

The invention provides a color repairing composition and a preparation method and application thereof. The color repairing composition is prepared from aqueous polyurethane resin, a co-solvent, a wetting agent, an anti-foaming agent, a bactericide and water; the combined quantity of the aqueous polyurethane resin, the co-solvent, the wetting agent, the anti-foaming agent, the bactericide and the water is 100% by weight, wherein the content of the aqueous polyurethane resin is 70-90% by weight, and the solid content of the aqueous polyurethane resin is 32-36%. A color modifier product includingthe color repairing composition is environmentally friendly, free of toxicity and good in flame retardancy, and the fire phenomenon cannot occur during transportation and use.

Description

technical field [0001] The invention relates to the field of paint preparation methods, and specifically discloses a color-correcting composition, a preparation method and an application thereof. Background technique [0002] Color correction agents are widely used in furniture and other decorations, but currently a large amount of ethanol is added to color correction agents on the market, which is prone to fire during transportation and use in furniture factories, and the volatilization of ethanol into the air has certain harmful effects on the human body. Harm, and pollute the air at the same time, especially for places such as furniture factories and high-end hotel furniture with high environmental protection requirements. Such color repairing products greatly increase potential safety hazards and endanger human health. Therefore, it is necessary to develop a safe and environmentally friendly color repairing agent product. Contents of the invention [0003] The purpose...
