Description

Technical Field

[0001] The invention belongs to the technical field of button production, and relates to a method for preparing shell buttons, and application of a treatment liquid in the preparation of shell buttons, and in particular to a method for preparing and application of a shell button with high-gloss ridged skin patterns. Background Art

[0002] On the market, shell buttons are all taken from snails and shellfish, with differences on the front and back. The inner side has strong pearlescent luster and uniform color, while the shell surface is the cuticle (shell skin), prismatic layer (shell layer) and nacre (shell bottom), with unclear or no pearlescent luster. Since shells are natural materials, it is inevitable that a part of the inner pearlescent luster will have defects, and customers demand buttons with bright pearlescent luster. Therefore, the usual method of manufacturing shell buttons will result in a large amount of shell raw materials being wasted and become waste blanks. Moreover, the existing process for processing shells is usually to use a grinder to mechanically grind the front and back of the shells to obtain shell blanks with smooth and pearlescent surfaces on both sides. Then, a laser is used to perform texture etching on the semi-finished shell buttons to obtain buttons with high pearlescent brightness and texture. However, this method has the following problems:

[0003] 1. After the front and back sides are smoothed, the shells become seriously thinner. The thinner the shells, the cheaper they are. This solution will weaken the value of the shells.

[0004] 2. After the thin blank is ground flat on both sides, it is too thin to make buttons, resulting in a large amount of material waste and becoming waste;

[0005] 3. The texture is etched one by one by laser, so the energy consumption is high, the cost is high, the efficiency is slow, and the texture of the finished products is monotonous and rigid in appearance, without the natural texture of the shell itself.

[0006] Therefore, how to obtain a method for preparing shell buttons and solve the above-mentioned problems existing in the existing process has become one of the urgent problems to be solved by cutting-edge manufacturers and many researchers in the industry. Summary of the invention

[0007] In view of this, the technical problem to be solved by the present invention is to provide a method for preparing shell buttons, the application of treatment liquid in the preparation of shell buttons, and particularly a method for preparing high-gloss ridged leather pattern shell buttons. The preparation method provided by the present invention particularly adopts a treatment liquid immersion method to improve the pearlescent effect of the shell surface of waste shell blanks, which can greatly improve the utilization rate of shell blanks; and the texture of the shell button product is the natural texture of the shell, which is obtained by immersion, and has the characteristics of mass production, high efficiency and low cost.
