Plastic component material is a material with reflective properties and obvious granularity, which is made through a specific production process. Under specific light, plastic components can show obvious reflective effects. In addition, they have excellent wear resistance, so they are often used for road markings. For example, China's utility model patent CN86203436U (publication date: 1987.01.07) discloses a plastic microbead retroreflective luminous signboard, which is composed of a plastic microbead board with a layer of fluorescent material coated on the reflective surface of the board.

[0003] Existing clothing reflective materials mostly use glass beads. For example, China invention patent application publication number CN106707386A (publication date 2017.05.24) provides a colorful high-brightness thermal film to solve the problem that the existing reflective film cannot achieve both high-brightness and colorful effects at the same time, including a hot-melt adhesive layer, the upper surface of the hot-melt adhesive layer is adhered with an adhesive layer, the upper surface of the adhesive layer has a plurality of grooves, each groove is inlaid with glass beads, the surface of the groove is plated with a multi-layer dielectric layer, the multi-layer dielectric layer includes a zinc sulfide coating layer, a silicon dioxide coating layer and a silicon monoxide coating layer, the zinc sulfide coating layer covers the surface of the groove, the silicon monoxide coating layer is bonded to the glass beads; the silicon dioxide coating layer covers the surface of the zinc sulfide coating layer, and the silicon monoxide coating layer covers the surface of the silicon dioxide coating layer.

[0004] As people's safety and aesthetic awareness continue to improve, the application of decorative materials is gradually expanding, and is tending to be more popular and demanding.

[0006] In order to solve the above technical problems, the purpose of the present invention is achieved through the following technical solutions:

[0011] A decorative adhesive layer, wherein a decorative pattern is arranged on the decorative adhesive layer;

[0012] The substrate layer provides a bearing structure for the decorative adhesive layer.

[0013] In the above-mentioned reflective material for plastic components, the nearly spherical shape means that the roundness of the plastic component is greater than 0.85, and there are no obvious edges and corners and depressions. Preferably, the roundness is greater than 0.95.

[0014] In the above-mentioned plastic component reflective material, the material of the plastic component can be selected from conventional materials, such as polyethylene (PE), polypropylene (PP), polystyrene (PS), polymethyl methacrylate (PMMA), etc., and nylon, ABS, etc. can also be used. Composite materials of various plastics can also be used, such as a multi-layer composite structure with PS as the core and PMMA as the shell.

[0015] In the above-mentioned reflective material for plastic components, the transparent glue layer is an adhesive layer, which meets the performance requirement of tightly connecting the plastic component and the processable transparent film.

[0016] In the above-mentioned plastic component reflective material, the plastic component layer, transparent adhesive layer and transparent film layer form a first pre-composite component, the decorative adhesive layer and substrate layer form a second pre-composite component, and the first pre-composite component and the second pre-composite component are composited to form the plastic component reflective material.

[0017] In the above-mentioned reflective material for plastic components, the transparent film layer is a processable transparent film, which is processed by spraying, printing or coating. The material of the transparent film layer is preferably a transparent film with high transparency and glue bonding strength such as PET film, PVC film and PC film, and there is no release effect on the surface; if coloring or patterning is required, a transparent film that can be sprayed with ink can be used; the coating can be a metal-plated film, such as aluminum plating.

[0018] In the above-mentioned reflective material for plastic components, the decorative adhesive layer includes a decorative material disposed therein, and the decorative material is selected from one or more of luminous materials, temperature-variable materials, light-variable materials, chameleon materials, and laser materials.

[0019] In the above-mentioned reflective material for plastic components, the substrate layer includes a base fabric or a base film, the base fabric is selected from T / C fabric, polyester-cotton fabric, nylon, stretch fabric, hot-melt film, PET, flame-retardant fabric and its derivative fabrics (such as printed fabric, etc.), and the base film is a PES hot-melt film or a TPU hot-melt film.

[0021] In the above-mentioned plastic component reflective material, a spray painting layer is arranged outside the plastic component layer.

[0022] The present invention also provides a method for preparing a plastic component reflective material, the method comprising the following steps:

[0023] 1. Scrape a transparent adhesive layer on the surface of the transparent film layer, evenly spread the plastic components on the transparent adhesive layer, and when the plastic components sink to a predetermined depth, cure the transparent adhesive layer to fix the plastic components on the transparent adhesive layer; in step 1, the sinking depth of the plastic components can be accurately controlled by controlling the viscosity and the sinking time of the transparent adhesive layer, and the curing method of the transparent adhesive layer adopts a common method in the art, such as temperature-controlled curing, light curing, etc.;

Processing the un-glued surface of the transparent film layer as required, wherein the processing method includes metallization, spray painting or printing; processing the outer surface of the plastic component layer as required, wherein the processing method is spray painting; after processing, a first pre-composite assembly is obtained;

[0025] 3. Scrape a decorative adhesive layer on the release film, and then laminate it with the substrate layer to obtain a second pre-laminated component;

[0026] Fourth, tear off the release film, compound the first pre-composite component and the second pre-composite component together, and obtain the plastic component reflective material after complete curing.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. The present invention provides a plastic component reflective material. When the plastic component is used in the reflective material for clothing, a unique granular texture can be obtained on the basis of the reflective effect, so that it presents a visual effect completely different from that of the glass microbead reflective material, providing a new aesthetic choice for the reflective material for clothing.

[0029] 2. Compared with traditional glass microbead reflective materials, the present invention greatly improves the flexibility and impact resistance of the material. By improving flexibility, the reflective film can better adapt to surfaces of different shapes and is not easily broken due to bending or folding. In some application scenarios that need to fit curved surfaces or are often impacted by external forces, such as vehicle body logos and reflective parts of wearable devices, reflective film using plastic microbeads can maintain longer-lasting integrity and reflective performance. By improving impact resistance, when the reflective film is hit or rubbed, the plastic microbeads are not easy to break, which can effectively reduce the decline in reflective performance caused by damage to the microbeads, and improve the durability of the reflective film in complex environments. In addition, the reflective material of the present invention also has other advantages such as light weight, low cost, and easy adjustment of optical properties.

[0030] 3. The present invention is provided with a transparent film layer that can be printed, sprayed, or coated, and a decorative adhesive layer containing various decorative materials. On the basis of having a reflective effect, it can also have a variety of color decorations and / or other decorative effects to meet the diverse and high-demand aesthetic needs of users.

[0031] 4. The present invention further optimizes the process of reflective materials, and the plastic component layer, transparent adhesive layer and transparent film layer are compounded to form a first pre-composite assembly; the decorative adhesive layer and the base material layer are compounded to form a second pre-composite assembly; and finally the first pre-composite assembly and the second pre-composite assembly are compounded to form a plastic component reflective material. Through the above process, processing can be convenient, while ensuring the decorative effect of the transparent film layer and the decorative adhesive layer, and the connection of each layer can be made more firm and not easy to peel off. Through the above process, the technical solution of the present invention can be applied to various types of base fabrics and base films, further expanding its application range.
