Description

Technical Field

[0001] This invention belongs to the field of genuine shell button production technology, and relates to a genuine shell button and its preparation method, an enamel adhesive, and particularly to a genuine shell button with partial enamel effect, its preparation method, and an enamel adhesive. Background Technology

[0002] As people's living standards improve, the diversification of clothing products has emerged, leading to high demand and increasingly fierce market competition in the button industry. Furthermore, the rise of fast fashion in recent years has transformed buttons from functional items to creative designs. With the development of the times, buttons have become increasingly diverse in terms of materials, shapes, and manufacturing processes. Consequently, manufacturers and consumers have placed various demands on traditional buttons.

[0003] Shell buttons, also known as natural shell buttons, are a very ancient type of natural button. They are primarily made from deep-sea shells, such as the white-lipped oyster from Australia, the black-lipped oyster from Tahitians, the horseshoe shell from the Solomon Islands, the brown-lipped oyster from Indonesia, the Japanese oyster (Pterocarpus santalinus), and the abalone shell from New Zealand. Shell buttons are elegant in texture and vibrant in color, made using traditional processing principles, making them a top choice for high-quality clothing. However, the current process for producing genuine shell buttons has the following defects: the surface effect is monotonous, achieving only a smooth and glossy localized adhesive color effect, without other gloss levels or shapes; after the genuine shell products are partially treated with glue, their application range with clothing is limited, and their product versatility is insufficient, resulting in weak market competitiveness and limited choices for customers using them in ready-made garments; because existing products directly apply glue to specific localized areas, the gloss and shape of the products are limited to a specific range, and the product effect is merely glossy without any appeal. After years of use in the market, customers have lost interest in products with a single gloss level and shape, and the lack of fashion and versatility prevents the continued integration with high-end and fashionable clothing.

[0004] Therefore, how to develop a surface treatment technology for genuine shell buttons, provide more suitable genuine shell buttons for the industry, obtain more natural and novel materials and effects, and better match with current fashion clothing has become one of the problems that R&D-oriented production enterprises and front-line researchers in the industry urgently need to solve. Summary of the Invention

[0005] In view of this, the technical problem to be solved by the present invention is to provide a genuine shell button and its preparation method, particularly a genuine shell button with a partial enamel effect. The genuine shell button prepared by the method provided by the present invention has a layered aesthetic effect of enamel on the surface, and the local color and smoothness of the surface can be matched with a wider range of clothing.

[0006] The present invention provides a genuine shell button, comprising a genuine shell button substrate and a resin with an enamel effect bonded to a portion of the genuine shell button substrate.

[0007] Preferably, the composite includes adhesive curing;

[0008] The enamel-effect resin can be laminated to the front and / or back of the shell button substrate.

[0019] The enamel adhesive includes enamel adhesive used for genuine mother-of-pearl buttons.

[0020] Preferably, the enamel adhesive further includes colorants and / or pearlescent colorants;

[0021] The amount of the pigment and / or pearlescent pigment added is 0.5 to 20 parts by weight;

[0022] The mass ratio of slurry A to slurry B is 3:(1 to 1.5).

[0023] This invention provides a method for preparing genuine shell buttons, comprising the following steps:

[0024] 1) After applying enamel glue to the surface of the pre-treated shell button semi-finished product, it is then dried and cured to obtain the shell button blank.

[0025] The enamel adhesive includes any one of the above-mentioned technical solutions;

[0026] 2) After shaping and polishing the shell button blanks obtained in the above steps, the finished shell button is obtained.

[0027] Preferably, the pretreatment step includes one or more of the following steps: blanking, grinding, button making, polishing, and spin drying;

[0028] Specifically, the blank is made from natural shell material to create a partially grooved semi-finished button.

[0029] Preferably, the location of the partial scraping groove includes the location for dripping enamel adhesive;

[0030] The polishing process also includes matte grinding and / or ultrasonic cleaning steps.

[0031] The area where the enamel adhesive is applied is the area where the enamel coating is applied.

[0032] Preferably, the mass ratio of the genuine shell button semi-finished product to the enamel adhesive is (96-98):(2-4);

[0033] The dripping rate is 2-3 seconds.

[0034] Preferably, the drying and curing temperature is 50–70°C;

[0035] The drying and curing time is 5 to 8 hours.

[0036] This invention provides a genuine shell button, comprising a genuine shell button substrate and a resin with an enamel effect bonded to a portion of the genuine shell button substrate. Compared with existing technologies, this invention addresses the limitations of existing genuine shell buttons, such as the lack of diverse surface effects, gloss levels, and design options. Furthermore, it addresses the numerous problems associated with partial resin application to genuine shell products. This invention creatively provides a genuine shell button with a resin that achieves a partial enamel effect. By employing a specific enamel adhesive and adding special additives to the material, this invention enhances the adhesion between the adhesive and the genuine shell material. This strengthens the adhesion, preventing the button from detaching during secondary shaping after the enamel adhesive is applied. It also ensures that the adhesive does not separate even after prolonged polishing and water-polishing, improving the finished product's wear resistance, washability, and solvent resistance. It also extends the lifespan of the adhesive bonded to different materials and enables new product effects such as two-tone designs and combinations of different materials, meeting the needs of customers in different styles of men's and women's wear, as well as sportswear, for matching and performance.

[0037] The natural shell button products provided by this invention possess a layered aesthetic with an enamel-like effect on their surface, while simultaneously enhancing the product's added value. This new surface treatment technology for shell buttons offers the industry a fresher and more natural effect, supplementing the range of applications for enamel treatment techniques and color combinations in button accessories. This allows for better matching with current fashion apparel, especially with the rise of high-end men's and women's fashion and sportswear. Buttons made from natural materials, with surface colors and finishes that can be matched with clothing in a wider range, significantly enhance the design and sophistication, meeting the matching needs of contemporary men's and women's fashion and sportswear, and greatly increasing market value.

[0038] Experimental results show that the enamel-effect genuine shell buttons prepared by this invention exhibit no wear or adhesive layer peeling on the overall surface. The overall quality meets industry standards for auxiliary materials, with no missing corners, rough edges, or a smooth, clean film layer. Performance-wise, they are resistant to washing, dry cleaning, and ironing, and the film layer does not wrinkle or peel. In particular, their resistance to continuous machine washing in household laundry and commercial dry cleaning far exceeds that of ordinary epoxy resin products in terms of wear resistance and adhesive layer strength.

[0072] Nan Ya A-type glue: Bisphenol A type resin: 80-100%

[0073] Benzyl alcohol: 15-20%

[0074] Defoamer: 0.5-1%

[0075] Antioxidant: 0.6-1%

[0076] Guodu B-type adhesive (model 2008AB): Composition (cyclohexanedimethylamine): 80-100%, benzyl alcohol 15-20% mixed to form B-type adhesive.

[0077] Mix adhesive A according to the above formula and disperse with a mixer for 20-30 minutes. Mix adhesive B according to the same formula and stir with a mixer for 5-10 minutes. Store the mixture separately in clean plastic containers, seal them well, and wait for use. The mixing ratio of adhesive A to adhesive B is 2:1. For colored and pearlescent finishes, add an additional 0.5-5% of the colorant.

[0078] After the semi-finished genuine shell buttons are prepared according to this invention, the unique enamel adhesive formula of this invention is used to enhance the adhesion between the buttons and the genuine shell material, as well as their shapeability and polishability. Simultaneously, when the finished product is used on clothing, its performance meets the requirements for washing resistance, dry cleaning resistance, and abrasion resistance. This is a significant advantage compared to other similar genuine shell products or similar products. Due to the special nature of buttons as an auxiliary industry, any improvements must meet relevant national, industry, or international standards to ultimately become qualified button products. The colored enamel effect achieved on the surface of the genuine shell buttons provided by this invention is achieved by dripping a specially formulated enamel adhesive material onto the button surface, followed by curing and drying to establish the bonding strength. Subsequent shaping and polishing processes result in finished buttons, achieving effects such as colored, pearlescent, transparent, and semi-transparent partial enamel effects. This invention, through the development of special enamel adhesive materials, combined with the selection of natural shell materials and the addition of other pigments and pearlescent colorants to the enamel adhesive materials, creates various surface treatment effects. This results in a variety of base colors and versatile accent colors for different product areas, allowing for diverse effects and color combinations on the button surface, effectively transforming product designs and catering to customer preferences. Furthermore, the finished buttons treated with enamel adhesive can have laser lettering applied to specific enamel areas, enhancing brand awareness for customers.

[0079] This invention also provides a method for preparing a genuine mother-of-pearl button, comprising the following steps:

[0080] 1) After applying enamel glue to the surface of the pre-treated shell button semi-finished product, it is then dried and cured to obtain the shell button blank.

[0081] The enamel adhesive includes any one of the above-mentioned technical solutions;

[0082] 2) After shaping and polishing the shell button blanks obtained in the above steps, the finished shell button is obtained.

[0083] The present invention first applies enamel adhesive to the surface of the pre-treated shell button semi-finished product, and then dries and cures it to obtain the shell button blank;

[0084] The enamel adhesive includes any one of the enamel adhesives described in the above technical solutions.

[0085] In this invention, the pretreatment step preferably includes one or more of the following steps: blanking, grinding, button making, polishing, and spin drying; more preferably, it includes multiple of the following steps: blanking, grinding, button making, polishing, and spin drying.

[0086] In this invention, the blank is preferably made of natural shell material to form a partially grooved semi-finished button.

[0087] In this invention, the location of the local scraping groove preferably includes the location for dripping enamel adhesive.

[0088] In this invention, the polishing process preferably includes a matte finishing and / or ultrasonic cleaning step, more preferably a matte finishing or ultrasonic cleaning step.

[0089] In this invention, the preferred location for applying the matte finish is the location where the enamel adhesive is applied.

[0090] This invention uses natural shell material to make semi-finished buttons with partial grooves, which are then polished to a matte finish and ultrasonically cleaned to enhance the bonding force between the enamel adhesive and the shell material.

[0091] In this invention, the preferred mass ratio of the semi-finished genuine shell button to the enamel adhesive is (96-98):(2-4), and more preferably (96.5-97.5):(2.5-3.5).

[0092] In this invention, the dripping speed is preferably 2 to 3 s, more preferably 2.2 to 2.8 s, and even more preferably 2.4 to 2.6 s.

[0093] In this invention, the drying and curing temperature is preferably 50-70°C, more preferably 54-66°C, and even more preferably 58-62°C.

[0094] In this invention, the drying and curing time is preferably 5 to 8 hours, more preferably 5.5 to 7.5 hours, and even more preferably 6 to 7 hours.

[0095] Finally, the present invention obtains the finished shell button by shaping and polishing the shell button blank obtained in the above steps.

[0096] In this invention, the buckle-making shape is a second buckle-making shape.

[0097] The present invention provides a method for preparing genuine shell buttons, the specific process of which includes: blank preparation → grinding → button making → polishing → spin drying → applying enamel glue → drying → button shaping → polishing to achieve gloss → finished product inspection and packaging. The purpose of this invention is to apply enamel glue to the surface or reverse side of the button, dry it, and then use the button making process for secondary shaping, scraping off the desired localized glue effect. The product shape can be customized according to the material and design requirements of the genuine shell, and the overall gloss level can be determined based on the final gloss requirements. This effectively solves the problem of existing processes: blank preparation → grinding → button making → polishing → spin drying → applying glue → drying → finished product inspection and packaging. Currently, mass-produced products using this method can only have transparent and colored glue layers applied directly to the surface, creating only a single glossy, colored, or transparent effect on a localized area of ​​the button surface, failing to achieve other gloss levels or other shapes. This invention improves the adhesion between the enamel adhesive and the genuine shell material by using a specific enamel adhesive and adding special additives. This enhances the adhesion of the adhesive to the shell material, preventing the enamel adhesive from falling off during secondary button shaping after the enamel adhesive is applied. It also prevents the adhesive from separating during long-term polishing and water polishing. This improves the wear resistance, washability, and solvent resistance of the finished product, and extends the service life of the adhesive when combined with different materials. At the same time, it can also achieve new product effects that combine two colors with different materials, meeting the needs of customers with different styles of men's and women's clothing and sportswear for matching and performance.

[0098] The present invention provides a genuine shell button with a partial enamel effect, its preparation method, and an enamel adhesive. The genuine shell button product provided by the present invention has a layered aesthetic effect reminiscent of enamel, while simultaneously enhancing the product's added value. This new surface treatment technology for genuine shell buttons provides the industry with a newer and more natural effect in genuine shell buttons, supplementing the application of enamel treatment technology and color matching in button accessories. It allows for better matching with current fashion apparel, especially with the rise of high-end men's and women's fashion and sportswear. Buttons made of natural materials, with surface colors and finishes that can be matched with clothing in a wider range, will significantly enhance the design and sophistication, meeting the matching needs of current fashionable men's and women's fashion and sportswear, and greatly increasing market value.

[0099] This invention provides the latest processing technology and genuine shell buttons for the garment accessories industry, enriching the variety of effects available for natural button products. These genuine shell buttons effectively supplement the market and customer demand for and application of natural product effects, enhancing the market competitiveness of genuine shell products and enabling button accessories with a partial enamel effect within the genuine shell product category. This invention enriches the production of high-end products using natural shell, providing customers with more choices and applications in various garment sectors.

[0100] Experimental results show that the enamel-effect genuine shell buttons prepared by this invention exhibit no wear or adhesive layer peeling on the overall surface. The overall quality meets industry standards for auxiliary materials, with no missing corners, rough edges, or a smooth, clean film layer. Performance-wise, they are resistant to washing, dry cleaning, and ironing, and the film layer does not wrinkle or peel. In particular, their resistance to continuous machine washing in household laundry and commercial dry cleaning far exceeds that of ordinary epoxy resin products in terms of wear resistance and adhesive layer strength.
