Description

Technical Field

[0001] This utility model relates to the field of eyeglass protection technology, and more specifically to an anti-scratch paint coating for eyeglasses. Background Technology

[0002] Eyeglass frames are structures used to support eyeglass lenses and fix the glasses to the wearer's face;

[0003] Eyeglass frames can be made of rigid, non-deformable materials: these materials usually refer to metals (such as titanium, stainless steel, etc.) or certain types of plastics. They are characterized by being sturdy and durable, not easily deformed, and suitable for long-term wear. They are a very good choice for frame designs that require high stability. In addition, some high-end rigid materials also have the advantages of being lightweight and corrosion-resistant, making them more comfortable to wear.

[0004] Eyeglass frames can be made of flexible and resilient materials: these materials include, but are not limited to, TR90 (a type of nylon material) and silicone. Their biggest feature is their high flexibility, which can adapt to different face shapes and is not easy to break when subjected to external forces. This makes them very suitable for children or sports, as these people may need frames with a certain degree of impact resistance and flexibility. At the same time, the soft material also increases the comfort of the wearer.

[0005] When manufacturing eyeglass frames, surface protection is generally required. Existing protective structures, such as those described in application number CN202321730131.6, "A High Antibacterial Topcoat Coating for Eyeglasses," provide various functional protective effects. However, when applied to eyeglass frames that are flexible and adaptable, the protective effect is not good and it does not adapt well to the deformation of the eyeglass frame. In particular, when providing wear-resistant and scratch-resistant functions, it has the disadvantage of being easy to fall off and crack. Utility Model Content

[0006] The purpose of this utility model is to provide an anti-scratch paint coating for eyeglasses in order to solve the above-mentioned technical problems.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] This invention proposes an anti-scratch paint coating for eyeglasses, which is flexible; the anti-scratch paint coating includes an adhesion layer, a reinforcing layer, an abrasion-resistant layer and a waterproof and oil-proof layer that are sequentially bonded and fixed.

[0009] As a preferred embodiment of this invention, the adhesive layer is a flexible epoxy resin coating.

[0010] As a preferred embodiment of this invention, the reinforcing layer is a polyurethane coating.

[0011] As a preferred embodiment of this invention, the wear-resistant layer is a silicon dioxide layer.

[0012] As a preferred embodiment of this invention, the waterproof and oil-proof layer is a perfluoropolyether modified silane coating.

[0013] The beneficial effects of this utility model are as follows:

[0014] By applying this scratch-resistant coating to the eyeglass frame, the flexibility provided allows for consistent deformation and wrapping as the eyeglass frame deforms, achieving both scratch resistance and high durability. The scratch-resistant coating is composed of an adhesion layer, a reinforcement layer, an abrasion-resistant layer, and a waterproof and oil-resistant layer, which, when applied to the surface of the eyeglass frame, provide a wealth of functional protection. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Figure reference numerals: Additive layer-1, Reinforcing layer-2, Wear-resistant layer-3, Waterproof and oil-proof layer-4. Detailed Implementation

[0017] like Figure 1 As shown, this utility model proposes: an anti-scratch paint coating for eyeglasses. The anti-scratch paint coating has flexibility. When the anti-scratch paint coating is applied to an eyeglass frame that can be flexible and deformable, the provided flexibility can be consistent with the deformation and wrapping of the eyeglass frame as it moves. It has anti-scratch function and also has the effect of high durability and strength.

[0018] Specifically: The scratch-resistant paint coating includes an adhesion layer 1, a reinforcing layer 2, an abrasion-resistant layer 3, and a waterproof and oil-resistant layer 4 that are sequentially bonded and fixed. The adhesion layer 1, the reinforcing layer 2, the abrasion-resistant layer 3, and the waterproof and oil-resistant layer 4 are sequentially applied to the surface of the eyeglass frame to provide multiple sets of functions.

[0019] Among them, the reinforcement layer 1 is a flexible epoxy resin coating, which can be formed on the eyeglass frame by spraying or other methods; it has excellent adhesion, chemical resistance, flexibility and corrosion resistance; the flexible epoxy resin coating is fixed on the surface of the eyeglass frame, which can improve the adhesion between subsequent layers and provide initial protection for the eyeglass frame.

[0020] The reinforcing layer 2 is a polyurethane coating, which can be formed on the reinforcement layer 1 by spraying or other methods; it can provide good flexibility, wear resistance, chemical resistance and excellent appearance; the polyurethane coating is fixed on the surface of the reinforcement layer 1, which can increase the flexibility and wear resistance of the overall structure, and can also play a certain role in cushioning.

[0021] The wear-resistant layer 3 is a silicon dioxide layer. This silicon dioxide layer can be formed on the surface of the reinforcing layer 2 by plasma-enhanced chemical vapor deposition (PECVD) to form a silicon dioxide film. The formed film is thin and uniform, which can significantly improve hardness and wear resistance, while not affecting its original flexibility and improving scratch resistance.

[0022] The waterproof and oil-repellent layer 4 is a perfluoropolyether-modified silane coating. This perfluoropolyether-modified silane is an existing material used to prepare hydrophobic and oleophobic surfaces. It not only provides excellent waterproof and oil-repellent properties, but its long molecular chains also contain many mobile parts, thus possessing considerable flexibility. This perfluoropolyether-modified silane coating can be formed on the surface of the wear-resistant layer 3 by chemical vapor deposition (CVD). When used on the surface of eyeglass frames, it can improve comfort, durability, and cleanliness.

[0023] The aforementioned eyeglass frame surface is sequentially coated with a flexible epoxy resin coating, a polyurethane coating, a silica layer, and a perfluoropolyether modified silane coating, which can provide a flexible wrapping protective effect.

[0024] Additional (not shown in the figure): also includes an antibacterial layer that is bonded and fixed between the reinforcing layer 2 and the wear-resistant layer 3. The antibacterial layer is composed of nano-silver ion particles and polyurethane paint. Specifically, the nano-silver ion particles are uniformly mixed in the polyurethane paint liquid and then applied to the surface of the reinforcing layer 2 by spraying or other methods to improve functionality and maintain flexibility.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
