preparation example Construction

[0035] see figure 1 , the embodiment of the present invention also provides a preparation method of shell material, comprising:

[0036] S20, placing the shell body in a dye solution for dip-dyeing to form a dye layer to obtain a dyed shell, the dye solution containing acid dye, acid and a first solvent; and

[0037] S40, placing the dyed shell in a reaction solution to react to form a metal oxide layer, and the reaction solution contains inorganic silver salt, inorganic copper salt, ammonia water and a second solvent.

[0038] The preparation method of the shell material in the embodiment of the present invention is simple. First, the shell body is dyed with dye to form a dye layer, and then the chemical reaction of inorganic silver salt or inorganic copper salt and ammonia water is used to form silver oxide and copper oxide precipitation, so that the dye layer A metal oxide layer is formed on it. The preparation method of the shell material can be applied to industrialized...

Embodiment 1

[0052] S20, mixing acid dyes BLACK B, Navy R and acetic acid in water to obtain a dye solution. The concentration of acid dye BLACK B is 5g / L, the concentration of Navy R is 3g / L, and the concentration of acetic acid is 0.5ml / L. According to the shell button body: dye solution = 1:5 (mass ratio), the shell button body is placed in the dye solution at 100°C (above 95°C), and the machine rotates slowly and dyes at a constant temperature for 30 minutes to obtain dyed shell buttons. Finally, rinse the dyed shell buttons with clean water.

[0053] S40, mixing silver nitrate, copper sulfate and ammonia water in water to obtain a reaction liquid. The concentration of silver nitrate is 8g / L, the concentration of copper sulfate is 80g / L, and the concentration of ammonia water is 200ml / L. According to dyeing shell buttons: dyeing solution = 1:2 (mass ratio), add the dyed shell buttons obtained in S20 to the reaction solution, raise the temperature of the reaction solution to 40°C and ...

Embodiment 2

[0055] Embodiment 2 is basically the same as Embodiment 1, the difference is only in:

[0056] The acid dye in step S20 is LANASET YELLOW 2R with a concentration of 2g / L. That is to replace the acid dyes BLACK B and Navy R with LANASET YELLOW 2R.

[0057] In step S40, the reaction time at constant temperature is 24 hours.

Abstract

A shell material, comprising a shell body, a dye layer and a metal oxide layer, the dye layer is disposed on the shell body, the metal oxide layer is disposed on the dye layer, and the metal oxide layer contains Silver oxide and copper oxide. A method for preparing a shell material, comprising: placing a shell body in a dye solution for dip-dyeing to form a dye layer to obtain a dyed shell, wherein the dye solution contains acid dye, acid and a first solvent; and placing the dyed shell in The metal oxide layer is formed by reacting in the reaction liquid, which contains inorganic silver salt, inorganic copper salt, ammonia water and a second solvent. A shell button, the shell button is made of the shell material or the shell material prepared by the shell material preparation method.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a shell material, a preparation method thereof and a shell button. Background technique [0002] Buttons are mainly divided into resin buttons, shell buttons, fruit buttons, cheese protein buttons, metal buttons and so on. Among them, shell buttons are derived from natural shells, with elegant texture, and are widely favored by the high-end consumer market. [0003] Since the main component of shells is calcium carbonate, the coloring of shells is different from buttons made of other materials. The dyeing of shells mainly adopts acid dyes or cationic dyes. The process of dyeing shells with acid dyes is to dye the shells with suitable acid dyes and dyeing assistants. The dyeing efficiency is high and the cost is low, but there is a problem of poor color fastness, especially for buttons dyed smoky gray. If the fastness is poor, the natural color of the shell surface will also det...
