AI Technical Summary
Existing lenses with a density greater than 1.0 will sink when dropped into water, making them difficult to find. Furthermore, the lack of suitable injection molding and reinforcement processes limits the development of water-floating sunglass lenses.
A cyclic block copolymer substrate is used, combined with a composite reinforcement layer, a REVO coating layer and an anti-reflective coating layer. The substrate density is less than that of water. The composite reinforcement layer is set on the inner and outer surfaces, and the REVO coating layer is set on the outer surface to enhance the floating performance and wear resistance. The adhesion of the coating layer is improved by vacuum plasma treatment.
The lenses float in water, providing safety and convenience, improved abrasion resistance, increased transparency, a variety of colors, and enhanced vibrant effects.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0022] It should be noted that the terms front, back, inner, outer, upper, lower, left, right, first, second, third and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the indicated technical features, unless otherwise explicitly and specifically limited.
[0023] As shown in Figures 1 to 3 The utility model discloses a kind of water floating sunglasses, with substrate 1, composite strengthening layer 2, REVO coating layer 3 and anti-reflection film layer 4.
[0024] The substrate 1 is made of cyclic block copolymer. The substrate 1 is specifically made of cyclic block copolymer (CBC) produced by Dow Chemical Co. The preferred thickness of the substrate 1 is 1.2-2.8mm. The density of cyclic block copolymer is 0.94g / cm 3 (Less than the density of water 1g / cm 3 So that the lens made will not sink when falling into water when moving on water, but will float on water surface, greatly convenient for user.
[0025] The composite strengthening layer 2 is arranged on the inner surface and the outer surface of the substrate 1 respectively, and the composite strengthening layer 2 is composed of a primer layer 21 and a topcoat layer 22. The primer layer 21 is a 7130 strengthening liquid coating layer, and the topcoat layer 22 is a 5140 strengthening liquid coating layer. Specifically, the 7130 strengthening liquid of the primer layer 21 and the 5140 strengthening liquid of the topcoat layer 22 are both products produced by SDC company of the United States. The preferred thickness of the primer layer 21 is 1-2 μm, and the preferred thickness of the topcoat layer 22 is 2-4 μm. The composite strengthening layer 2 can improve the wear-resistant and scratch-resistant effect of the lens.
[0026] A reflection-reducing film layer 4 is arranged on the inner surface composite strengthening layer 2 of the substrate 1. The reflection-reducing film layer 4 can specifically be formed by alternately arranging titanium pentoxide and silicon dioxide. The preferred thickness of the reflection-reducing film layer 4 is 90-110 nm. The reflection-reducing film layer 4 reduces the reflection of light reflected from the back surface of the lens to the eyes, increases the perspective, and makes the line of sight clearer.
[0027] A REVO film layer 3 is arranged on the outer surface composite strengthening layer 2 of the substrate 1. The preferred thickness of the REVO film layer 3 is 80-150 nm. The REVO film layer 3 can be plated with different colors of REVO as needed to meet the diversified color requirements, making the lens color more flexible and rich, and increasing the sparkling effect of the lens.
[0028] In order to improve the adhesion of the subsequent film layers such as the composite strengthening layer 2, the inner surface and the outer surface of the substrate 1 are further subjected to vacuum plasma treatment 500W / 300S, and the composite strengthening layer 2, the REVO film layer 3 (or the reflection-reducing film layer 4) are sequentially arranged on the vacuum plasma treated surface.
[0029] In the specific processing and production of the utility model, the processing technology is as follows:
[0030] First step, the manufacturing of the substrate 1:
[0031] The raw material of the substrate 1 is the cyclic block copolymer CBC floating material produced by the Dow Chemical Co. of the United States. The CBC floating material is dehumidified and molded by a mold to form the substrate 1 of the lens, so that the lens has the floating property. The thickness of the substrate 1 is controlled to be 1.2-2.8 mm.
[0032] Second step, the manufacturing of the vacuum plasma treatment:
[0033] The inner surface and the outer surface of the substrate 1 are subjected to vacuum plasma treatment 500W / 300S to improve the adhesion of the subsequent film layers.
[0034] Third step, the manufacturing of the composite strengthening layer 2:
[0035] A layer of 7130 strengthening liquid and a layer of 5140 strengthening liquid are coated on the vacuum plasma treated surface of the inner surface and the outer surface of the substrate 1 to form a primer layer 21 and a topcoat layer 22. The 7130 strengthening liquid and the 5140 strengthening liquid are specifically the products produced by the SDC company of the United States. The thickness of the primer layer 21 is controlled to be 1-2 μm, and the thickness of the topcoat layer 22 is controlled to be 2-4 μm. The composite strengthening layer 2 enhances the hardness of the lens and improves the wear resistance and scratch resistance of the lens.
[0036] Fourth step, the manufacturing of the reflection-reducing film layer 4:
[0037] An antireflective coating layer 4 is formed on the composite reinforcement layer 2 on the inner surface of the substrate 1 by vacuum evaporation. The specific thickness of this antireflective coating layer 4 is controlled between 90nm and 110nm. This antireflective coating layer 4 can reduce the reflection of light from the back of the lens to the eye, making the vision clearer.
[0038] Step 5, Fabrication of REVO coating layer 3:
[0039] A REVO coating layer 3 is formed on the composite reinforcement layer 2 on the outer surface of the substrate 1 by vacuum evaporation. The specific thickness of this REVO coating layer 3 is controlled between 80-150nm, and different colors of REVO can be deposited as needed to make the lens colors more flexible and richer, and increase the lens's dazzling effect.
[0040] Thus, a finished product of the floating sunglasses lens of this utility model is obtained.
[0041] The finished product of this invention, after testing, not only has high buoyancy, ensuring it won't sink even if dropped into water during water sports, but also meets all performance standards for sunglass lenses (hardness, abrasion resistance, adhesion, flexibility). The lens transmittance reaches 96%, and the reflectivity reaches 0.56% (e.g., ...). Figure 3 (As shown). The hardness test showed that the lens hardness reached 2H or higher. It was then rubbed back and forth 10 times with a pencil of the corresponding hardness and a 200g weight. The abrasion resistance test showed that it could withstand 0000# steel wool and rubbed back and forth 30 times with a 200g weight. The key observation was that there were no scratches on the outer surface of the lens.
[0042] The above description is merely an example of the implementation of this utility model and is not intended to limit the scope of protection of this utility model. It should be noted that any equivalent changes made by those skilled in the art after reading this specification, based on the design concept of this case, shall fall within the scope of protection of this case.
