Description

Recycled materials with visualization

The present invention is related to resource recycling and reuse; in particular, it refers to a visualized recycled material.

According to the trend, the promotion of material recycling and resource recycling to reduce environmental load is a trend and a topic for everyone. Take plastic products as an example. Plastic materials are widely used due to their excellent material properties, light weight, high plasticity, and low production price. In contrast, the accumulation of plastic products in the environment not only causes damage to wildlife and habitats, but even Negative impact on humans.

For this reason, responding to "plastic reduction" is the first step to practice green life. However, because people still cannot break away from the economic model of plastics, they are derived from the "remodeling" model of recycling and reuse in addition to "plastic reduction". The diversified application of the company not only saves costs, but also contributes to the practice of carbon reduction. Therefore, how to recreate the value of recycled materials after recycling is an urgent goal for the relevant industry.

In view of this, the purpose of the present invention is to provide a visualized recycled material, which can increase the added value of recycled materials through a rich and varied visual presentation.

In order to achieve the above objective, the present invention provides a visualized recycled material, including a first recycled material and a second recycled material, wherein the first recycled material has a corresponding first form transformation temperature, and the second recycled material The material has a corresponding second form transformation temperature. When a processing temperature is greater than the first form transformation temperature or the second form transformation temperature, the first recycle material or the second recycle material undergoes form transformation and is cooled Then, it turns into a solid state, so that the mixed first recycled material and the second recycled material form the visualized recycled material.

The effect of the present invention is to make the surface of the recycled material present a visual effect to add additional value, and the recycled material can be recycled.

The composition of the visualized recycled material of the present invention is taken from reusable materials, which is first heated to produce a morphological transformation and then cooled to form a material with a predetermined thickness. The aforementioned reusable materials include but are not limited to rubber, polyurethane (PU), thermoplastic polyurethane (TPU), thermoplastic rubber (TPR), ethylene-vinyl acetate copolymer (EVA) Or secondary EVA foam material (Phylon), etc. The other material may not be limited to the above-mentioned plasticized material, and can be fiber materials such as wood fiber, bamboo fiber or cloth such as non-woven fabric, woven fabric or leather.

Please refer to Figures 1 to 4, the visualized recycled material 100 of the first preferred embodiment of the present invention includes a first recycled material 10 and a second recycled material 20, the first recycled material 10 and the second recycled material 10 The two recycled materials 20 are respectively taken from most solid granular materials after pulverization of plastic products, wherein the first recycled material 10 has a corresponding first form transformation temperature T1, and the second recycled material 20 has a corresponding second form transformation Temperature T2. Because the first recycled material 10 and the second recycled material 20 of this embodiment are made of different materials, for example, the first recycled material 10 is EVA, and the second recycled material 20 is thermoplastic polyurethane (TPU). Therefore, the first recycled material 10 and the second recycled material 20 are made of different materials. The first form transformation temperature T1 of the recovered material 10 is lower than the second form transformation temperature T2 of the second recovered material 20. In this embodiment, the aforementioned first and second form transformation temperatures refer to the softening temperature.

The first recycled material 10 and the second recycled material 20 are mixed and put into the cavity C of a mold M. If necessary, the first recycled material 10 and the second recycled material 20 in the cavity C can be stirred to make The mixing is more uniform. Then, a processing temperature T is applied to the first reclaimed material 10 and the second reclaimed material 20, and the processing temperature T is greater than the first form transformation temperature T1 of the first reclaimed material 10 but less than the second reclaimed material 20. The second form transformation temperature T2, based on the aforementioned processing conditions, when the processing temperature T reaches greater than the first form transformation temperature T1, the first recycled material 10 will undergo form transformation, that is, turn from a solid state to a softened or molten state. Since the processing temperature T is still lower than the second form conversion temperature T2, the second recycled material 20 remains solid, and the softened first recycled material 10 will partially or completely cover the second recycled material 20. After that, the first recycled material 10 is cooled and transformed into a solid state, so that the second recycled material 20 is filled in the first recycled material 10 as shown in FIGS. 3 and 4.

It can be seen from the above that by controlling the processing temperature T to be greater than the first form conversion temperature T1 but less than the second form conversion temperature T2, and then after cooling, the first recycled material 10 covered with the second recycled material 20 can be obtained to obtain the recycled material 100 Since the second recycled material 20 is arranged irregularly, the surface of the recycled material 100 exhibits a visual effect. The recycled material 100 can not only be recycled, but also adds additional value due to the visual effect.

It should be noted that when the first recycled material 10 and the second recycled material 20 have different colors, the combination of colors can make the surface of the recycled material 100 more variability and enrich the visual effect. It is worth mentioning that when one of the first recycled material 10 or the second recycled material 20 is a transparent material, and the other is a non-transparent material, the recycled material 100 will exhibit a three-dimensional effect or depth. Sense of visual effects.

In addition, the surface of the recycled material 100 can be processed to produce predetermined or special textures or totems, or have both textures and totems. The aforementioned textures and totems can be formed by embossing or transfer technology. The surface of the recycled material 100, the embossing means is, for example, a pre-engraved mold or a roller to apply pressure on the surface of the recycled material 100, and the transfer technology is, for example, using a release film method to apply pressure on the release film. The textures and totems of are transferred to the surface of the recycled material 100. Taking Figure 5 as an example, it is disclosed that the totem 101 is embossed on the surface of the recycled material 100 to make the surface of the recycled material more diverse.

The surface of the recycled material 100 may be flat as shown in FIG. 4, or it may be uneven as shown in FIG. 6, that is, through the aforementioned embossing technique, the surface of the recycled material 100 is embossed to form a three-dimensional appearance and Tactile effect. In addition, in the selection of the first recycled material 10 and the second recycled material 20, the complementation of physical properties can be considered. For example, when the first recycled material 10 is EVA with good flexibility and elasticity, the second recycled material 20 can choose hardness. Highly wear-resistant thermoplastic elastomer (TPU), so that the recycled material 100 after the combination of the first recycled material 10 and the second recycled material 20 can have the unique characteristics of two different materials at the same time.

In the above embodiment, two different recycled materials are used to produce a recyclable recycled material 100 with visual effects. However, in other practices, a third recycled material can also be added as required. Please refer to Figures 7 and 8 As shown, the third recycled material 30 has a corresponding third form transformation temperature T3, the third form transformation temperature T3 also refers to the softening temperature, and the third form transformation temperature T3 is between the first form transformation temperature T1 and the first form transformation temperature T3. The transformation temperature of the two forms is between T2. When the processing temperature T is greater than the first form conversion temperature T1, less than the second form conversion temperature T2, close to the third form conversion temperature T3, the first recycled material 10, the second recycled material 20, and the third recycled material 30 Causes different degrees of deformation, such as complete deformation, partial deformation, undeformed, etc., after cooling, a richer and more varied recycled material 100A will be obtained. In the same way, the first recycled material 10, the second recycled material 20, and the third recycled material 30 of the recycled material 100A can be of different colors to enrich the visual effect, or they can be processed with embossing, transfer printing and other technologies to have texture and totem. . Similarly, the surface of the recycled material 100A composed of the first recycled material 10, the second recycled material 20, and the third recycled material 30 may be irregular. Based on the foregoing knowledge, the composition of recycled materials may not be limited to two or three types of recycled materials. Of course, they may also be composed of more recycled materials. Even recycled materials need not be limited to being composed entirely of plastic. The participation of different properties and recycled materials to enrich the remolded products.

The above-mentioned various forms of recycled materials use different materials as the first recycled material, the second recycled material and even the third recycled material, so they have different form conversion temperatures. When the processing temperature is applied, the aforementioned recycled materials will be produced. Different degrees of deformation, or even failure to deform and retain the existing solid state. After cooling, the fully deformed, partially deformed, and undeformed recycled materials are combined to obtain a changeable and visualized recycling. material. It must be emphasized that the aforementioned recycled materials can also be taken from the same material and have the same form transformation temperature. The difference is that they have different colors. When the applied processing temperature reaches the form transformation temperature, all recycled materials start It produces softening deformation, and then through moderate cooling treatment, it can effectively control the deformation and transform it into a solid state due to cooling. The timing of the aforementioned cooling treatment can be selected after the reclaimed material is completely deformed, or at the beginning of partial deformation.

In addition to making the above-mentioned various forms of recycled materials, other methods, such as extrusion molding, hot pressing, or vacuum pressing, can all be used to produce visualized recycled materials. It should be noted that, although the morphological transition temperature in the above-mentioned embodiment is the softening temperature, in other application examples, the morphological transition temperature may also refer to the melting temperature (Tm) temperature. In addition, the softening temperature may be the glass transition temperature (Glass Transition temperature, Tg).

The following describes other embodiments of the recycled material of the present invention. Please refer to the recycled material 200 shown in FIG. 9, which is composed of not only the above-mentioned first recycled material 10 and second recycled material 20, but also includes a substrate 40. It is defined that the first recycled material 10 and the second recycled material 20 that have undergone morphological transformation and become solid after cooling are mixed to form a substrate 50 with a predetermined thickness, and the substrate 40 may be pre-laid or later attached to the aforementioned One side of the substrate 50, more specifically, the substrate 50 has a first surface 50a and a second surface 50b opposite to each other. The substrate 40 is bonded to the first surface 50a of the substrate 50, and the second surface of the substrate 50 50b mainly presents a visual aspect. The aforementioned substrate 40 may be one or a combination selected from the group consisting of woven fabric, non-woven fabric, plastic film, rubber film, and fiber, and has the effect of strengthening the structure of the substrate 50.

The recovered material 300 shown in FIG. 10 is different from the above-mentioned recovered material 200 in that the substrate 40A has a structured surface that is attached to the first surface 50a of the substrate 50, and the structured surface has at least one convex portion 42 so that the bottom The second surface 50b of the material 50 is relatively bulging at the position corresponding to the convex portion 42. In other words, the shape and number of the bulging of the second surface 50b are determined by the structure surface, which can enrich the visual experience of the recycled material 300. .
