preparation example Construction

[0027] The preparation method of the above-mentioned environment-friendly strip-shaped copper-gold powder, the specific steps are as follows:

[0028] Step 1: Weighing 3%-15% of alcohol-soluble resin and 85%-97% of absolute ethanol according to mass percentage, and the sum of the mass percentages of the above components is 100%;

[0029] Step 2: dissolving the alcohol-soluble resinous resin weighed in step 1 into absolute ethanol to obtain an adhesive;

[0030] Step 3: Take 70%-85% of the original copper-gold powder and 15%-30% of the adhesive obtained in step 2 according to the mass percentage, the sum of the mass percentages of the above components is 100%, and the copper-gold original powder and the The adhesive is put into the JB300-D mixing mixer, and the mixture is evenly mixed to obtain the mixture;

[0031] Step 4: Add the mixture obtained in step 3 into a YK-100 swinging granulator, and granulate with a screen aperture of 3-6 mm to obtain undried strip-shaped copper-...

Embodiment 1

[0034] Take 0.45 g of alcohol-soluble polymerized rosin and mix with 14.55 g of absolute ethanol to fully dissolve it to obtain an adhesive. Then take 85 grams of copper-gold powder and adhesive and put it into a mixer and mix evenly, prepare strip-shaped copper-gold powder with a granulator, and finally dry it in an oven at 60° C. for 1.5 hours.

Embodiment 2

[0036] Take 1 gram of alcohol-soluble polymerized rosin and fully dissolve it in 19 grams of absolute ethanol solvent to form an adhesive. Then take 80 grams of copper-gold powder and adhesive and put it into a mixer and mix evenly, prepare strip-shaped copper-gold powder with a granulator, and finally go through vacuum drying at 60° C. for 1.5 hours.

Abstract

The invention discloses an environment-friendly strip-shaped copper-gold powder, which is composed of the following components according to the mass percentage: 70%-85% of copper-gold raw powder, 15%-30% of an adhesive, and the sum of the mass percentages of the above components is 100%. ; The adhesive is composed of the following components by mass percentage: alcohol-soluble resin 3%-15%, absolute ethanol 85%-97%, and the sum of the above-mentioned components by mass percentage is 100%. The formula of the present invention does not contain toxic solvents, which improves the requirements of environmental protection; avoids the problem of dust pollution generated in the use process, and the strip-shaped copper-gold powder is easy to sell and transport; the alcohol-soluble resin is mixed with copper-gold powder to make copper The surface of the gold powder is coated with a layer of resin, which is isolated from the oxygen in the air and reduces the oxidation of the copper gold powder. Compared with the raw material powder, the glossiness of the printed gold is improved to varying degrees, up to 25%. The invention also discloses a preparation method of the environmental-friendly strip-shaped copper-gold powder.

Description

technical field [0001] The invention belongs to the technical field of metal pigments, and in particular relates to an environment-friendly strip-shaped copper-gold powder, and also relates to a preparation method of the above-mentioned environment-friendly strip-shaped copper-gold powder. Background technique [0002] With the improvement of copper and gold powder production efficiency and continuous improvement of product quality, the application field of copper and gold powder has gradually expanded. From the initial painting and decoration to the gold printing ink in the printing industry, it has been widely used in decorative coatings, architecture, and decorations. , printing and other industries. However, copper-gold powder needs to be ground into very fine flaky powder during the preparation process, resulting in a large specific surface area, active chemical properties, easy oxidation in the air, and easy suspension in the air, resulting in dust pollution. Moreover...
