preparation example Construction

[0047] In the present invention, the preparation method of the button topcoat preferably comprises the following steps:

[0048] Colorless saturated polyester resin, colored polyurethane elastic particles of 80-150 μm, polyurethane elastic powder of 5-10 μm, plant fiber powder of 80-150 μm, leveling agent, matting powder, hand feeling agent, drier, butyl acetate , diacetone alcohol and cyclohexanone are mixed to obtain material A;

[0049] Material A, material B and material C are mixed to obtain a top coat for buttons, the material B is an isocyanate curing agent, and material C is butyl acetate.

[0050] The invention provides a method for preparing a skin texture imitation stone button, comprising the following steps:

[0051] mixing the unsaturated resin, styrene, color paste, cobalt naphthenate and methyl ethyl ketone peroxide to obtain a blank slurry;

[0052] Making a blank from the blank-making slurry to obtain a button blank;

[0053] The button blank is buttoned and...

Embodiment 1

[0063] Mixed slurry for blank making: mix 710g of 989 unsaturated resin with 290g of styrene to obtain a mixed solution, then add gray slurry and 8ml of cobalt naphthenate and stir well, then add 10ml of methyl ethyl ketone peroxide, After uniform stirring, the billet slurry is obtained.

[0064] Blank-making and button-making process: After the blank-making slurry obtained in the above steps is processed by a centrifuge, a button blank with a thickness of 5.5mm is obtained; then the above-mentioned button blank is made into a button blank with a side thickness of 3.0mm and a diameter of A button shape of 15.0 mm, depth 1.5 mm, hole distance 3.5 mm, and hole diameter 2.1 mm is used to obtain a semi-finished resin button.

[0065] Polishing: Pour the semi-finished resin buttons made by the button making machine into the polishing machine, and carry out water rolling polishing with a polishing stone for 5 hours to remove the burrs and uneven knife feet left during the button mak...

Embodiment 2

[0074] Mixed slurry for blank making: Mix 700g of 989 unsaturated resin with 300g of styrene to obtain a mixed solution, then add blue-gray color paste and 9ml of cobalt naphthenate to it and stir well, then add 10ml of peroxide Methyl ethyl ketone, after stirring evenly, obtain the billet slurry.

[0075] Blank-making and button-making process: After the blank-making slurry obtained in the above steps is processed by a centrifuge, a button blank with a thickness of 2.5mm is obtained; then the above-mentioned button blank is made into a button with a thickness of 2.1mm and a single hole by a button making machine A button shape with a diameter of 4.5 mm is obtained to obtain a semi-finished resin button.

[0076] Polishing: Pour the semi-finished resin buttons made by the button making machine into the polishing machine, and use the polishing stone for water tumbling polishing for 4 hours to remove the burrs and uneven knife legs left during the button making.

Abstract

The invention provides finishing coat for a button, a skin-texture stone-like button and a preparation method thereof. The finishing coat comprises a material A, a material B and a material C in a mass ratio of (8-10):1:(2.5-3.5), wherein the material A comprises colorless saturated polyester resin, 80-150 microns of colorful polyurethane elastic particles, 5-10 microns of polyurethane elastic powder, 80-150 microns of plant fiber powder, a flatting agent, matt powder, a feeling agent, a drier, n-butyl acetate, diacetone alcohol and cyclohexanone; the material B is an isocyanate curing agent;and the material C is n-butyl acetate. The components of the finishing coat for the button are compatible with each other, and the finishing coat is sprayed to the button surface, so that the button has a stone-like appearance, skin texture and relatively high color fastness. The button coated with the finishing coat has a color fastness being 4-5 grade, and after five times of washing, color variety is 4-5 grade, and the surface does not have remarkable defect.

Description

technical field [0001] The invention relates to the technical field of buttons, in particular to a top coat for buttons, a stone-like button with skin texture and a preparation method thereof. Background technique [0002] Buttons are the main decorative items in the design of clothing, and play a vital role in the aesthetics of clothing. The accessories on clothing are combined with the current fashion trend, and buttons with natural effect products are becoming more and more popular among customers. Among them, stone-like buttons, as a recently popular effect, are highly sought after. [0003] More common in the market is the injection-molded imitation stone button, and its preparation process includes: using plastic materials with an imitation stone effect for color matching and injection molding. Because it is injection molding, it is difficult to avoid the sprue on the surface of the button, which is a defect for high-end customers, giving people a sense of cheapness, ...
