Description

Technical Field

[0001] The utility model belongs to the technical field of pointed-bottom diamonds, in particular to a pointed-bottom diamond with polyamide hot-melt adhesive. Background Art

[0002] Rhinestone, also known as crystal diamond and rhinestone, is mainly composed of crystal glass. It is a kind of jewelry accessory obtained by grinding, polishing and cutting glass into diamond facets, making it have a colorful and gorgeous appearance like natural diamonds. It is an important embellishment supporting material for jewelry, shoes, handicrafts, clothing, luggage and leather goods, and has a huge market.

[0003] At present, the diamonds on the market are mainly divided into flat-bottom diamonds and pointed-bottom diamonds. Flat-bottom diamonds are further divided into those with hot-melt adhesive and those without hot-melt adhesive. The ones with hot-melt adhesive are called hot-drills in the market; flat-bottom hot-drills have a hot-melt adhesive layer on the bottom plane, which can be directly adhered to objects by hot pressing and heating; pointed-bottom diamonds are also called water diamonds in the market. They have a diamond shape composed of an inverted rhombus shape at the bottom and a horizontal surface on the face. The bottom of the water diamond is then coated with a reflective layer and a protective layer (to protect the paint) to make it have a refractive and reflective effect and brightness similar to that of a diamond.

[0004] Among the existing rhinestones on the market, the existing technology cannot realize the pointed bottom drill with hot melt glue on the bottom of the rhinestone cone, so the use of the existing rhinestones is limited to relying on AB glue, acrylic pressed heat-sensitive glue and other processing methods to bond with objects for embellishment effect, which greatly reduces the scope of use, especially for clothing fabrics, leather, shoes, bags and other fabrics. The scope of use cannot achieve the purpose of adding highlights and added value to the products by heating and pressing with hot melt glue on the bottom like hot rhinestones. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the utility model provides a pointed-bottom water rhinestone with built-in polyamide hot-melt adhesive, so that the bottom of the pointed-bottom water rhinestone has its own adhesive, and can be directly adhered to an object by heating and pressing, and can also be fixed by using AB glue or acrylic thermosensitive adhesive processing methods, avoiding the situation where the water rhinestone is fixed only by relying on the processing methods of AB glue and acrylic thermosensitive adhesive, expanding the use scope of the water rhinestone, and achieving the technical effect of convenient hot-melt pasting.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: the utility model proposes a pointed-bottom rhinestone with built-in polyamide hot-melt adhesive, comprising a pointed-bottom rhinestone body, the bottom of which is sequentially provided with an oxide film layer, a paint layer and a polyamide hot-melt adhesive layer, the oxide film layer is connected to the pointed-bottom rhinestone body, the paint layer is arranged on the oxide film layer, the polyamide hot-melt adhesive layer is arranged on the paint layer, and the paint layer is arranged between the polyamide hot-melt adhesive layer and the oxide film layer.

[0007] As an improvement, the pointed-bottom rhinestone body has a conical cut-out bottom, the pointed-bottom rhinestone body is in the shape of a cone head, and the side surface of the cone is cut into a plurality of equally divided planes.

[0008] As an improvement, the oxide film layer is attached to the bottom of the pointed-bottom rhinestone by one of vacuum electroplating and water electroplating. The thickness of the oxide film layer can be set according to actual requirements. After the light is emitted from the oxide film layer and the pointed-bottom rhinestone body, a glittering effect of light refraction is generated, making the rhinestone present a colorful and glittering effect.

[0009] As an improvement, the paint layer is a special protective gold oil for crystal glass products, which is composed of a primer, a primer curing agent, a topcoat and a topcoat curing agent in a component bottom-surface combination. The paint layer is attached to the bottom of the pointed-bottom rhinestone body of the oxide layer by spraying. After the light passes through the oxide film layer, the pointed-bottom rhinestone body reflects a bright and shiny effect through the refraction of the conical section bottom. The main function is to protect the oxide layer at the bottom of the attached rhinestone and the hot melt adhesive attachment fusion processing to prepare for the next step.

[0010] As an improvement, the polyamide hot melt adhesive layer is made of polyamide resin powder particles. The melt viscosity of the polyamide hot melt adhesive layer is 2000-3500CPS, with good adhesion effect, applicable temperature of 100-200°C, high heat resistance, good fluidity, and both adhesion and anti-sticking properties. The thickness of the polyamide hot melt adhesive layer is less than or equal to 0.3mm.

[0011] The beneficial effects achieved by the utility model with the above structure are as follows: the pointed-bottom rhinestone with polyamide hot-melt adhesive proposed in the scheme is no longer limited to the previous processing method. After the pointed-bottom rhinestone body is cut and polished, an oxide film layer, a paint layer and a polyamide hot-melt adhesive layer are sequentially arranged on the bottom. The principle of flat-bottom hot-drilling is applied to the pointed-bottom rhinestone, which not only ensures the dazzling luster of the rhinestone itself refracted by the conical cross section, but also has the advantage of being more glittering and colorful than flat-bottom hot-drilling, and is more convenient for hot-melt pasting, especially for embellishment on cloth fabrics and leather of clothing, shoes, bags, etc., and is more widely applicable;

[0012] Unlike flat-bottom rhinestones, which are coated with polyamide resin powdered hot melt adhesive on the bottom, flat-bottom rhinestones are coated with polyamide resin powdered hot melt adhesive by using a sieve to sprinkle the powdered hot melt adhesive micro-particles on the bottom of the flat-bottom rhinestone, while pointed-bottom rhinestones cannot be coated with powdered hot melt adhesive micro-particles in this way. Electrostatic spraying equipment must be used to use the electrostatic spraying process to evenly apply the powdered hot melt adhesive to the conical bottom of the rhinestone.
