Abstract
Description
Technical Field
[0001] The invention relates to the field of multi-color soles, and more specifically to a multi-color gradient sole and a preparation method thereof. Background Art
[0002] The structure of the sole is quite complex. In a broad sense, it can include all the materials that make up the sole, such as the outsole, midsole and heel. In a narrow sense, it only refers to the outsole. The common characteristics of general sole materials should be wear resistance, water resistance, oil resistance, heat resistance, pressure resistance, impact resistance, good elasticity, easy to fit the foot shape, not easy to deform after shaping, heat preservation, easy to absorb moisture, etc. At the same time, it must be matched with the midsole to have a braking effect when walking and changing feet so as not to slip and easy to stop. There are many types of sole materials, which can be divided into natural sole materials and synthetic sole materials. Natural sole materials include natural sole leather, bamboo, wood, etc., and synthetic sole materials include rubber, plastic, rubber and plastic composite materials, recycled leather, elastic cardboard, etc. Existing transparent or translucent soles include materials such as TPR, rubber, TPU, PU, PVC, PC, etc. The soles are generally formed by foaming the above materials. The foamed products have the properties of softness, good elasticity, and chemical corrosion resistance. Therefore, they are widely used as shoe materials in slippers, sandals, casual shoes and other shoes.
[0003] The existing multi-color gradient soles are generally fixed in color after coloring. The color of the soles will be the color when they leave the factory. Although there are multiple colors, they are too rigid and cannot adapt to the diversified shoe market and cannot keep up with consumers' demand for more diverse sole colors. At the same time, in existing products, although the soles are also multi-colored, due to the problem of investment cost, the gradient processing is not natural enough, and sudden color changes often occur, or the gradient area is too narrow, resulting in a sudden color change visually, which makes the visual sense of disharmony very strong. If the gradient processing is to be natural, it is inevitable to increase the cost investment, which increases the overall investment of the manufacturer in the shoes. Summary of the invention
[0004] 1. Technical issues to be solved
[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a multi-color gradient sole and a preparation method thereof, which can be used in combination with an inner core interlayer and a rear color-changing ball, so that when walking, the rear color-changing ball is repeatedly squeezed by the inner core interlayer, so that the contact area with the upper transparent bottom and the lower transparent bottom is repeatedly increased and restored, so that the color of the rear color-changing ball is repeatedly superimposed and restored with the upper transparent bottom and the lower transparent bottom, so that visually, the color changes and then recovers continuously, so that the sole can achieve a visual effect of continuous color change in the case of multiple colors, and at night, with the setting of fluorescent powder, it can also achieve a color-changing and flashing effect. At the same time, during the preparation, by using a uniform color gradient sticker, on the one hand, compared with the prior art, the material and processing of the uniform color gradient sticker are common, without increasing too much cost investment, and at the same time, it can also make the gradient more natural, reduce the visual sense of disharmony, and improve the visual effect.
[0006] 2. Technical solution
[0007] To solve the above problems, the present invention adopts the following technical solutions.
[0008] A multi-color gradient sole comprises a sole body, wherein the sole body comprises an upper transparent sole and a lower transparent sole, wherein the upper transparent sole and the lower transparent sole are bonded to each other, and the upper transparent sole is located above the lower transparent sole, and two clamping grooves are bored at the ends of the upper transparent sole and the lower transparent sole that are close to each other, and two opposite clamping grooves form a sandwich cavity, wherein an inner core sandwich is placed in the sandwich cavity, and the two inner core sandwiches are respectively in contact with the inner walls of the sides of the two sandwich cavities that are close to each other, and a plurality of evenly distributed rear color-changing balls are placed between the inner core sandwich and the other three inner walls of the clamping groove, and the two ends of the rear color-changing balls are respectively in compression contact with the clamping groove and the inner core sandwich, and a force-bearing cavity, a passive cavity and micropores are bored at the inner end of the inner core sandwich, and the passive cavity is located outside the force-bearing cavity, and the force-bearing cavity and the passive cavity are connected through the micropores. The inner core interlayer and the rear color-changing ball are connected, and can be used in conjunction with each other, so that when walking, the rear color-changing ball is repeatedly squeezed by the inner core interlayer, so that the contact area with the upper transparent bottom and the lower transparent bottom is repeatedly increased and restored, so that the color of the rear color-changing ball is repeatedly superimposed and restored with the upper transparent bottom and the lower transparent bottom, so that visually, the color changes and then recovers continuously, so that the sole of the shoe can achieve a visual effect of constantly changing color in the case of multiple colors, and at night, with the setting of fluorescent powder, it can also achieve a color-changing and flashing effect. At the same time, during the preparation, by using uniform color gradient stickers, on the one hand, compared with the existing technology, the materials and processing of the uniform color gradient stickers are common, without increasing too much cost investment, and at the same time, the gradient can be made more natural, reduce the visual sense of disharmony, and improve the visual effect.
[0009] Furthermore, a plurality of spherical bulges are fixedly connected at both the upper and lower ends of the inner core interlayer, and the shape of the force-bearing cavity matches the spherical bulge. On the one hand, the spherical bulge enables the shoes made of the sole to massage the sole to a certain extent, and on the other hand, its outwardly protruding shape allows more air to be stored in the force-bearing cavity of the inner core interlayer, so that when the foot steps on it, the passive cavity will expand to a greater extent, thereby increasing the squeezing force on the rear color-changing ball, increasing the contact area between the rear color-changing ball and the sole body, and visually making the color-changing effect between the upper transparent sole and the lower transparent sole more obvious.
[0010] Furthermore, the upper and lower inner walls of the force-bearing cavity are fixedly connected with a plurality of evenly distributed connecting columns, and the connecting columns are alternately distributed with the spherical bulges. The connecting columns can improve the overall strength of the inner core interlayer so that it will not be completely squeezed and flattened during use, so that when wearing shoes made of the sole, the deformation of the sole will not be too large to affect comfort.
[0011] Furthermore, a plurality of centering beads are placed in the force-bearing cavity, and the centering beads are located between the upper and lower spherical bulges. The centering beads are solid structures, which can increase the hardness of the spherical bulge, making the massage effect of the sole of the foot more obvious, and at the same time can assist the connecting column to increase the supporting effect on the inner core interlayer.
[0012] Furthermore, the rear color-changing ball includes a colored inner core and a color-developing outer capsule, wherein the colored inner core is located inside the color-developing outer capsule, and the color-developing outer capsule can restrain the colored inner core so that it can return to its original state when repeatedly subjected to force from the sole of the foot, thereby increasing the service life of the rear color-changing ball.
[0013] Furthermore, the colored inner core is made of colored clay, and the color-developing outer capsule is made of elastic colorless and transparent material. The color of the colored inner core can be selected according to actual needs. It can be the same color as the upper transparent bottom and the lower transparent bottom, or it can be other colors, so that it can present another color after being superimposed with the upper transparent bottom and the lower transparent bottom. The color-developing outer capsule is colorless and transparent, so that the color of the colored inner core can be revealed through the color-developing outer capsule.
[0014] Furthermore, the colored mud of the colored inner core is mixed with fluorescent powder, and the ratio of the colored mud to the fluorescent powder is 1:0.5-0.8, so that at night, when walking, the fluorescent color of the rear color-changing ball can be seen through the upper transparent bottom and the lower transparent bottom, thereby improving the visibility of the color of the sole at night, thereby improving the aesthetics of the sole.
[0015] A multi-color gradient sole, the preparation method of which comprises the following steps:
[0016] S1. Preparation before coloring: clean the upper transparent base and the lower transparent base to be colored;
[0017] S2, select two or three colors of nano paints required, and then select one of the nano paints as a primer, and soak the upper transparent base and the lower transparent base in the nano paint for 10s-300s, so that the A, B and C areas all present the color of the transparent primer;
[0018] S3, gradient color development treatment of area A, paste a 2-3 cm wide uniform color gradient sticker between areas A and B of the upper transparent base and the lower transparent base dried in S2, and immerse area A in the nano paint of the second color under the same conditions as S2, with the boundary being the edge of the uniform color gradient sticker close to area B, so that area A presents the superimposed color of the translucent second nano paint and the nano paint used as the primer;
[0019] S4, a gradient color development process is performed in the C region, and S3 is repeated, so that the C region presents the superimposed color of the semi-transparent third nano-paint and the nano-paint as the primer;
[0020] S5. Let it dry to obtain the desired multi-color gradient sole.
[0021] Furthermore, it also includes S6, filling the inner core interlayer and the rear color-changing ball between the upper transparent bottom and the lower transparent bottom, and bonding the upper transparent bottom and the lower transparent bottom together. The immersion of the nano paint is carried out in a hot water bath at 30-80°C. The hot water bath can accelerate the coloring on the one hand, and on the other hand, it can make the heat uniform during immersion, thereby making the coloring more uniform.
[0022] Furthermore, a blending layer is adhered to the lower end of the uniform color gradient sticker, and the two sides of the upper end of the uniform color gradient sticker are respectively arranged as a solid layer and a semi-transparent layer, and a plurality of liquid inlet holes are drilled on the semi-transparent layer, and the density of the liquid inlet holes is proportional to the distance between the holes and the solid layer. The use of the uniform color gradient sticker makes the color gradient at the boundary between areas A and B, and areas B and C more natural. From the side of the uniform color gradient sticker close to B to the other side, the color of S3 and S4 immersed in nano paint gradually deepens instead of suddenly deepening, which makes the gradient more natural and improves the aesthetics of the sole.
[0023] 3. Beneficial effects
[0024] Compared with the prior art, the advantages of the present invention are:
[0025] (1) This solution can achieve a continuous color-changing visual effect in the case of multiple colors by using an inner core interlayer and a rear color-changing ball. At the same time, by using a uniform color gradient sticker during preparation, compared with the prior art, the materials and processing of the uniform color gradient sticker are common, and the cost investment is not increased too much. At the same time, the gradient can be made more natural, reduce the visual disharmony, and improve the visual effect.
[0026] (2) Multiple spherical bulges are fixedly connected to the upper and lower ends of the inner core interlayer, and the shape of the stress-bearing cavity matches the spherical bulge. On the one hand, the spherical bulge enables the shoes made of the sole to achieve a certain massage effect on the sole. On the other hand, its outward protruding shape allows more air to be stored in the stress-bearing cavity of the inner core interlayer, so that when the foot steps on it, the passive cavity will expand to a greater extent, so that the squeezing force on the rear color-changing ball is greater, the contact area between the rear color-changing ball and the sole body is larger, and the visual color change effect between the upper transparent sole and the lower transparent sole is more obvious.
[0027] (3) A plurality of evenly distributed connecting columns are fixedly connected to the upper and lower inner walls of the stress-bearing cavity, and the connecting columns are alternately distributed with the spherical bulges. The connecting columns can improve the overall strength of the inner core interlayer so that it will not be completely squeezed and flattened during use, so that when wearing shoes made of the sole, the deformation of the sole will not be too large to affect the comfort.
[0028] (4) A plurality of centering beads are placed in the force-bearing cavity. The centering beads are located between the upper and lower spherical bulges. The centering beads are solid structures, which can increase the hardness of the spherical bulge, making the massage effect of the sole of the foot more obvious. At the same time, they can assist the connecting column to increase the supporting effect on the inner core interlayer.
[0029] (5) The rear color-changing ball includes a colored inner core and a color-developing outer capsule. The colored inner core is located inside the color-developing outer capsule. The color-developing outer capsule can bind the colored inner core so that it can return to its original state when repeatedly subjected to force from the sole of the foot, thereby increasing the service life of the rear color-changing ball.
[0030] (6) The colored inner core is made of colored clay, and the color-developing outer capsule is made of an elastic colorless and transparent material. The color of the colored inner core can be selected according to actual needs. It can be the same color as the color of the upper transparent bottom and the lower transparent bottom, or it can be other colors so that it can present another color after being superimposed with the upper transparent bottom and the lower transparent bottom. The color-developing outer capsule is colorless and transparent so that the color of the colored inner core can be revealed through the color-developing outer capsule.
[0031] (7) The colored clay of the colored inner core is mixed with fluorescent powder, and the ratio of the colored clay to the fluorescent powder is 1:0.5-0.8, so that at night, when walking, the fluorescent color of the rear color-changing ball can be seen through the upper transparent bottom and the lower transparent bottom, thereby improving the visibility of the color of the sole at night, thereby improving the aesthetics of the sole.
[0032] (8) The immersion of the nano-paint is carried out in a hot water bath at 30-80°C. The hot water bath can accelerate the coloring process on the one hand, and on the other hand, it can make the heat even during the immersion process, thereby making the coloring more uniform.
[0033] (9) A shading layer is adhered to the lower end of the uniform color gradient sticker, and the upper two sides of the uniform color gradient sticker are respectively arranged as a solid layer and a semi-transparent layer. A plurality of liquid inlet holes are drilled on the semi-transparent layer, and the density of the liquid inlet holes is proportional to the distance between the holes and the solid layer. The use of the uniform color gradient sticker makes the color gradient at the boundary between the A and B areas and the B and C areas more natural. From the side of the uniform color gradient sticker close to B to the other side, the color of S3 and S4 immersed in nano paint gradually deepens instead of suddenly deepening, making the gradient more natural and improving the aesthetics of the sole.

The method for preparing a multi-color gradient sole according to claim 1, characterized in that: The following steps are involved: S1, preparation before coloring, cleaning the upper transparent base (101) and the lower transparent base (102) to be colored; S2, selecting two or three colors of nano paints required, and then selecting one of the nano paints as a primer, and soaking the upper transparent base (101) and the lower transparent base (102) in the nano paint for 10s-300s, so that the A, B and C areas all show the color of the transparent primer; S3, gradient color development treatment of area A, the upper transparent base (101) and the lower transparent base (102) dried in S2 are placed in the nano paint. A 2-3 cm wide uniform color gradient sticker is pasted between the A and B regions of the transparent sole (102). Under the same conditions as S2, the A region is immersed in the nano paint of the second color, with the boundary being the edge of the uniform color gradient sticker close to the B region, so that the A region presents the superimposed color of the translucent second nano paint and the nano paint used as the primer; S4, the C region is subjected to a gradient color development process, and S3 is repeated, so that the C region presents the superimposed color of the translucent third nano paint and the nano paint used as the primer; S5, drying is performed to obtain the desired multi-color gradient sole.
7. The method for preparing a multi-color gradient sole according to claim 6, characterized in that: It also includes S6, filling the inner core interlayer and the rear color-changing ball (2) between the upper transparent base (101) and the lower transparent base (102), and bonding the upper transparent base (101) and the lower transparent base (102) together, and the immersion of the nano paint is carried out in a hot water bath at 30-80°C.
