preparation example Construction

[0054] The present invention has no special limitation on the preparation method of the button slurry, and the technical solution of mixing and stirring the above-mentioned components uniformly to obtain the mixed slurry is sufficient.

[0055] The present invention adopts the above-mentioned button slurry with specific content components to prepare finished buttons, and each component can realize better interaction, and can make the obtained finished buttons more suitable for laser treatment, thereby obtaining high contrast and stable effect. Resin buttons with laser discoloration effect and high yield.

[0056] The present invention also provides a method for preparing a button with a laser discoloration effect, comprising the following steps:

[0057] a) The button slurry is solidified and molded, button-made and polished in sequence to obtain a finished button; the button slurry is the button slurry described in the above technical scheme;

[0058] b) performing laser tre...

Embodiment 1

[0080] (1) 80 parts by weight of unsaturated resin, 5.0 parts by weight of styrene, 1.0 parts by weight of color paste, 20 parts by weight of aluminum silicate (KAlSi 3 o 8 ) mixed with 1.0 parts by weight of cobalt naphthenate, stirred uniformly, then added 1.2 parts by weight of methyl ethyl ketone peroxide and stirred uniformly again to obtain a mixed slurry.

Abstract

The invention provides a button slurry, a button with a laser color changing effect, and a preparation method thereof. The preparation method comprises following steps: (a) curing and moulding the button slurry mentioned above, producing buttons, and polishing the buttons to obtain finished button products; and (b) processing the finished button products by laser to obtain buttons with a laser color changing effect. Compared with the prior art, the finished button product is prepared from the button slurry with a special formula, and then the finished button product is processed by laser to obtain the resin button with a high contrast ratio, stable effect, and laser color changing effect. The yield is high. The experiment results show that on the basis that the original precision of workpiece is guaranteed, the markers on the resin button is clear and durable, the marking speed is quick, the physical and chemical properties of the resin button are good, the button quality is high, andthe uniformity of obtained buttons is good.

Description

technical field [0001] The invention relates to the technical field of buttons, and more specifically relates to a button slurry, a button with laser discoloration effect and a preparation method thereof. Background technique [0002] There are many ways to mark on products, such as screen printing, transfer printing, embossing, ink printing, etc., and these methods are all surface printing. Traditional printing marking technology, due to mechanical damage, friction or chemical action, makes the marking blurred and incomplete, and it is difficult to identify; at the same time, due to the need for a large amount of ink, the cost is high, the environmental pollution is serious, and it is difficult to apply on curved surfaces or Textured surface. At the same time, due to friction, mechanical damage, chemical action and similar effects during storage and transportation, these marks may easily cause the marks on the goods to be blurred and difficult to identify; The product bri...
