Description

Technical Field

[0001] The invention relates to the technical field of garment accessory manufacturing, and in particular to a method for forming textures on a product surface by utilizing ultraviolet laser. Background Art

[0002] In current industrial production, the texture and pattern forming technology of product surface is very important, which not only affects the aesthetics of the product, but also the durability and added value of the product. Traditionally, the formation of texture and pattern mainly relies on processes such as rubbing and transfer engraving, which encounter many challenges when processing certain specific materials, such as inert silicone materials.

[0003] Due to its unique physical and chemical properties, inert silicone materials make it particularly difficult to form clear and lasting patterns and textures on their surfaces. Traditional processing methods usually require pre-treatment on the surface of silicone materials, such as grinding and cleaning, to improve its adhesion to other materials. However, even after such treatment, subsequent processes such as inkjet, screen printing, and printing still have difficulty in forming clear and stable patterns on the surface of silicone materials. Especially in daily use such as washing in washing machines, patterns are prone to fading and lightening, which seriously affects the aesthetics and durability of the product.

[0004] In order to overcome these difficulties, the traditional practice in the industry is to use too many color dispensing, screen printing, vulcanization and other processes for direct molding. However, these methods are not only complex and costly, but also have a long production cycle, and cannot meet the dual requirements of modern industrial production for efficiency and cost control. In addition, due to the rough lines and complex processes, the products made by these methods often lack fineness and beauty, and cannot meet consumers' pursuit of high quality in product appearance.

[0005] Therefore, how to develop a new technology that can efficiently and stably form clear, colorful textures and patterns on the surface of inert silica gel materials has become an urgent problem to be solved in current industrial production. It is in this context that this technical solution proposes a method for forming textures on the surface of products using ultraviolet lasers, aiming to successfully form clear and colorful texture patterns on the surface of products by adding nano-scale powders to the base material, and through pretreatment and ultraviolet laser marking, thereby overcoming the shortcomings of traditional technologies and improving production efficiency and product quality. Summary of the invention

[0006] In view of the deficiencies of the prior art, the present invention provides a method for forming textures on the surface of a product using ultraviolet laser, which solves the problems raised by the above-mentioned background technology.

[0007] To achieve the above purpose, the present invention is implemented by the following technical solution: a method for forming a texture on a product surface using a purple laser, comprising the following steps: S1. Add nano-scale powder to the base material and perform pretreatment; S2. Use a purple laser marking machine to laser mark the pre-treated products.

[0008] Furthermore, the base material is any one of vulcanized silicone material, thermoplastic material, and thermosetting material.

[0009] Furthermore, the nano-scale powder is any one of rare metal powder and non-metal powder, and the content of the nano-scale powder in the base material is greater than 3%.

[0010] Furthermore, the pretreatment step includes extrusion, stirring and refining to ensure uniform distribution of the powder in the base material.

[0011] Furthermore, the purple laser marking machine uses computer graphic design software to edit and design patterns, and performs laser marking on the pre-treated products.

[0012] Furthermore, the laser marking step forms a clear pattern on the surface of the inert material, and the pattern has clear lines and rich colors.

[0013] Furthermore, environmentally friendly additives are added to the base material.

[0014] Furthermore, the environmentally friendly additive is any one of a biodegradable additive, a halogen-free flame retardant additive, an antioxidant additive, a laser-sensitive additive and an environmentally friendly plasticizer, and the content thereof in the base material is greater than 5%.

[0015] Furthermore, the method can reduce waste and energy consumption in the production process.

[0016] Furthermore, the method is applicable to products of various shapes and sizes, and the pattern design is flexible and diverse to meet personalized needs.

[0017] The present invention provides a method for forming textures on the surface of a product using a purple laser. Compared with the prior art, it has the following beneficial effects: 1. This method significantly improves the material's absorption and reflection properties of ultraviolet light by adding nano-powder to the vulcanized silicone material and pre-treating it. This improvement enables the laser to act on the material surface more efficiently, thereby forming a texture pattern with clear lines and rich colors on the product. Compared with traditional processes, this method not only improves the accuracy and speed of marking, but also greatly enhances the visual effect and aesthetics of the pattern; 2. This method introduces environmentally friendly additives, such as biodegradable additives, halogen-free flame retardant additives, antioxidant additives, etc. The addition of these additives not only helps to reduce waste and energy consumption in the production process, but also significantly improves the environmental performance of the product. For example, biodegradable additives allow the product to be more easily decomposed by the natural environment after use, reducing pollution to the environment; halogen-free flame retardant additives improve the flame retardant properties of the material without producing harmful gases, thereby enhancing the safety of the product; 3. This method is not only applicable to vulcanized silicone materials, but can also be extended to other basic materials, such as thermoplastic materials, thermosetting materials, etc., providing a wealth of texture molding options for products of different materials. At the same time, using computer graphic design software, various personalized patterns can be easily edited and designed to meet the diverse needs of consumers. This feature makes this method have significant advantages in producing customized and differentiated products; 4. Compared with traditional processes, this method effectively reduces production costs by simplifying the production process, reducing material waste and energy consumption. At the same time, the speed and accuracy of the purple laser marking technology also greatly improve production efficiency, shorten the product launch cycle, and enhance the market competitiveness of enterprises; 5. This method not only solves the problems existing in traditional texture forming technology, but also brings new technical innovation ideas to the industry. By introducing environmentally friendly additives and ultraviolet laser marking technology, this method provides strong support for promoting sustainable development and green production in the industry.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0020] The present invention provides a technical solution: a method for forming a texture on a product surface using a purple laser, comprising the following steps: S1: Material preparation and pretreatment First, a base material is selected. In this embodiment, a vulcanized silicone material is selected as an example. Then, nano-scale powder is added to the vulcanized silicone material. The powder is one of rare metal powder (such as silver powder) or non-metal powder (such as silicon dioxide powder), and its content in the base material is set to 5% (which can be adjusted according to actual needs, but should be ensured to be no less than 3%). Then, the mixed material is pretreated. The pretreatment steps include extrusion, stirring and refining to ensure that the nano-scale powder is evenly distributed in the vulcanized silicone material to avoid the occurrence of agglomeration. S2: Purple laser marking After the pretreatment is completed, the product is placed on the workbench of the purple laser marking machine. Using computer graphic design software, edit and design the required pattern. Subsequently, the purple laser marking machine laser marks the product according to the designed pattern. Due to the addition of nano-scale powder, the absorption and reflection characteristics of the vulcanized silicone material to purple light are improved, allowing the laser to act more efficiently on the surface of the material to form a clear pattern. The pattern has clear lines and rich colors, meeting the design requirements.

[0021] This example successfully forms a clear and colorful texture pattern on the product surface by adding nano-scale powder to the base material, pre-treating and marking with a purple laser. This method not only improves the efficiency and quality of laser marking, but also adds a unique visual effect to the product. Embodiment 2

[0022] The present invention provides a technical solution: a method for forming a texture on a product surface using a purple laser. On the basis of the technical solution of Example 1, an environmentally friendly additive is further introduced to reduce waste and energy consumption in the production process and improve the environmental performance of the product. The specific steps are as follows: S1: Material preparation and pretreatment First, a base material (still a vulcanized silicone material in this example) is selected, and nano-scale powder (such as silver powder or silicon dioxide powder) is added thereto, and its content in the base material is still 5%, and then an environmentally friendly additive is added to the mixed material. The environmentally friendly additive selected in this embodiment is a biodegradable additive (such as a starch derivative), and its content in the base material is set to 7% (it can be adjusted according to actual needs, but it should be ensured to be not less than 5%), and then the mixed material is pre-treated, including extrusion, stirring and refining, to ensure that the nano-scale powder and the environmentally friendly additive are evenly distributed in the vulcanized silicone material; S2: Purple laser marking After the pretreatment is completed, the product is placed on the workbench of the purple laser marking machine. Using computer graphic design software, the required pattern is edited and designed. Subsequently, the purple laser marking machine laser marks the product according to the designed pattern. Due to the addition of nano-scale powder and environmentally friendly additives, the absorption and reflection characteristics of the vulcanized silicone material to purple light are further optimized, allowing the laser to act more efficiently on the surface of the material, forming a clearer and more colorful pattern.

[0023] This embodiment not only successfully forms a clear and colorful texture pattern on the surface of the product by adding nano-powder and environmentally friendly additives to the base material, and after pretreatment and ultraviolet laser marking, but also significantly improves the environmental performance of the product. At the same time, due to the addition of environmentally friendly additives, waste and energy consumption in the production process are reduced, which meets the requirements of sustainable development. This method is not only applicable to vulcanized silicone materials, but can also be extended to other basic materials (such as thermoplastic materials, thermosetting materials), and personalized pattern design can be performed according to customer needs.

[0024] In addition, it should be noted that the environmentally friendly additives of this embodiment may also be halogen-free flame retardant additives, antioxidant additives, laser-sensitive additives and environmentally friendly plasticizers. Specifically: 1. When selecting halogen-free flame retardant additives, the specific preferred ones are: aluminum hydroxide, magnesium hydroxide, red phosphorus, etc., which can improve the flame retardant properties of the basic materials without producing harmful gases. They prevent the spread of fire by absorbing heat, diluting the concentration of combustible gases, and forming an insulating layer.

[0025] 2. When selecting antioxidant additives, the preferred ones are: hindered phenols, phosphites, thioesters, etc., which can inhibit the degradation and aging of the basic materials due to oxidation during processing and use, thereby extending the service life of the product.

[0026] 3. When selecting laser-sensitive additives, it is preferred to use special metal oxides, dyes, etc., which can enhance the absorption and reflection characteristics of the base material to the laser, thereby improving the efficiency and effect of laser marking. They are usually matched with specific laser wavelengths to achieve the best marking effect.

[0027] 4. When selecting environmentally friendly plasticizers, the preferred ones are: epoxidized soybean oil, triethyl citrate, etc., which can improve the softness and plasticity of the base material, making it easier to process and shape. At the same time, they have less impact on the environment and will not release harmful gases.
