Problems solved by technology

However, the film quality is brittle, the adhesion is poor, and the heat resistance and weather resistance are also poor. Due to the simple alcohol solvent volatilization and water absorption, the coating is easy to lose luster.

Embodiment 1

[0024] First, 10g of blue toner is added to 90g of a mixed solvent composed of toluene, ethanol, and ethyl acetate (4:2:1 by weight), stirred and dissolved evenly to make a blue color paste; then 30g of air-drying polymer Ester resin, 51g toluene, 10g ethanol, 5g ethyl acetate, 2g propylene glycol monobutyl ether were mixed and stirred evenly to make a resin solution; finally, 2g of the above blue color paste was added to the above resin solution, and stirred evenly to form blue light gold water.

[0025] The preparation method of the air-drying polyester resin in this example is: put 35kg of tung oil, 34kg of tris(2-hydroxyethyl)isocyanurate, and 10g of lithium hydroxide into the reaction kettle, gradually raise the temperature to 240°C and keep it warm until the sample test 1:5 methanol is clear and transparent, reaching the end of alcoholysis. Cool down to 180°C, add 31kg of methyltetrahydrophthalic anhydride and 10kg of refluxing xylene, gradually raise the temperature to 1...

Embodiment 2

[0031] First, 20g of green toner is added to 80g of a mixed solvent composed of toluene, ethanol, and ethyl acetate (4:2:2 by weight), stirred and dissolved evenly to make a green color paste; then 20g of air-drying polymer Ester resin, 39g toluene, 20g ethanol, 10g ethyl acetate, and 10g propylene glycol monobutyl ether were mixed and stirred evenly to make a resin solution; finally, 1g of the above green color paste was added to the above resin solution, and stirred evenly to form a green pale gold water.

[0032] The preparation method of the air-drying polyester resin in this example is as follows: put 37kg of tung oil, 36kg of tris(2-hydroxyethyl)isocyanurate, and 20g of lithium hydroxide into the reaction kettle, gradually raise the temperature to 250°C and keep it warm until the sample test 1:5 methanol is clear and transparent, reaching the end point of alcoholysis. Cool down to 180°C, add 27kg of methyltetrahydrophthalic anhydride and 10kg of refluxing xylene, graduall...

Embodiment 3

[0039] Mix and stir 25g of air-drying polyester resin, 50g of toluene, 15g of ethanol, 5g of ethyl acetate, and 5g of propylene glycol monobutyl ether to make a resin solution and obtain colorless light gold water.

[0040] The preparation method of the air-drying polyester resin in this example is: put 36kg of tung oil, 35kg of tris(2-hydroxyethyl)isocyanurate, and 15g of lithium hydroxide into the reaction kettle, gradually raise the temperature to 245°C and keep it warm until the sample test 1:5 methanol is clear and transparent, reaching the end point of alcoholysis. Cool down to 180°C, add 29kg of methyltetrahydrophthalic anhydride and 10kg of refluxing xylene, gradually raise the temperature to 195°C, reflux and dehydrate until the end of the reaction (resin: xylene = 1 : 1 hour coating 4 viscosity over 60 seconds), put into the dilution tank, cool down to below 100 ℃, add 70kg of toluene and 20kg of 120# solvent oil, stir evenly, filter and pack.

Abstract

The invention discloses gold lacquer, a preparation method and application thereof. The gold lacquer comprises air-drying polyester resin, blended solvent and also can comprise a small quantity of pigment and color paste. The preparation method is as follows: firstly adding toner into a mixed solvent comprising methylbenzene, ethanol and ethyl acetate, stirring and uniformly dissolving to preparethe toner; and then according to the matching, mixing and blending uniformly air-drying polyester resin, methylbenzene, ethanol, ethyl acetate and propylene glycol n-butyl ether to prepare resin solution; and finally adding the toner into the resin solution, and uniformly stirring. The gold lacquer is characterized by strong adhesive force, good heat resistance, dampproof, good rust-proof effect,bright paint film color, fast room temperature drying, etc.

Description

technical field [0001] The invention relates to a paint, in particular to a light gold water and its preparation method and application. Background technique [0002] Danjinshui is mainly used for the bottom layer of high-grade furniture paint, enameled wire coating, atmospheric metal rust prevention, motor rotor rust prevention, etc. The traditional Danjinshui is shellac type, also known as shellac varnish, shellac varnish, commonly known as bubble water (polish ), which is mainly composed of shellac, rosin, ethanol and butanol, pigments, and additives. When in use, soak it with a brush or cotton wool, and gently wipe it on the polished metal surface. After the solvent volatilizes, it forms a A layer of transparent film, adhered to the metal surface, has excellent hardness and electrical insulation, and can be polished to show a bright color. However, the film quality is brittle, the adhesion is poor, and the heat resistance and weather resistance are also poor. Because th...
