Description

Technical Field

[0001] This utility model relates to the field of PVC sheet technology, specifically to a color reflective high-strength PVC sheet. Background Technology

[0002] PVC sheet, or polyvinyl chloride sheet, is a thermoplastic plastic sheet made from polyvinyl chloride resin as the main raw material, with the addition of plasticizers, stabilizers, lubricants and other additives, through processes such as mixing, plasticizing, calendering or extrusion. It has the characteristics of being lightweight and inexpensive, having excellent processing performance and strong chemical stability. The formula and process can be adjusted according to different needs to achieve the conversion between soft and rigid properties, making it an indispensable material in modern industrial production and daily life.

[0003] In the prior art, Chinese Patent Publication No. CN219927171U discloses a high-adhesion PVC sheet, including a PVC sheet body, a waterproof layer on the surface of the PVC sheet body, a waterproof adhesive layer fixedly connected below the waterproof layer, a fireproof layer fixedly connected below the waterproof adhesive layer, a middle stabilizing layer fixedly connected below the fireproof layer, a bottom layer fixedly connected below the middle stabilizing layer, and a reinforcing layer fixedly connected below the bottom layer. The waterproof layer on the surface of the PVC sheet body is a seepage-proof material made of high molecular polymer as the basic raw material, which can prevent liquid from seeping into the interior of the PVC sheet body. In addition, the waterproof adhesive layer of polyurethane glue can further improve the waterproof effect of the PVC sheet body, and minimize the possibility of liquid seeping into the interior of the PVC sheet body and being unable to evaporate, thus preventing damage to the overall structure of the PVC sheet body.

[0004] Based on the above materials, the existing PVC sheets have relatively limited color options, making it difficult to meet diverse decoration and design needs. At the same time, their reflective properties are poor, limiting their application in situations where light reflection is required. Therefore, we propose a colored reflective high-strength PVC sheet. Utility Model Content

[0005] The purpose of this utility model is to provide a colored reflective high-strength PVC sheet to solve the problems mentioned in the background art, such as the limited color of existing PVC sheets, which makes it difficult to meet diverse decoration and design needs, and the poor reflective performance, which limits their application in situations where light reflection is required.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a color reflective high-strength PVC sheet, comprising a PVC substrate layer, wherein a color reflective composite layer for reflecting colors is provided on one side of the PVC substrate layer, the color reflective composite layer comprising a primer layer, a color pigment layer and a reflective layer stacked sequentially, and a reinforcing layer for increasing the strength of the PVC substrate layer is provided on the other side of the PVC substrate layer.

[0007] Furthermore, the primer layer is coated on one side of the outer wall of the PVC substrate layer, and the primer layer is an acrylic resin coating with a thickness of 5-10 μm.

[0008] Furthermore, the colored pigment layer is disposed on the outer wall of the primer layer, and the colored pigment layer is a mixture of organic pigment and PVC resin, and the pigment particle size is ≤50μm.

[0009] Furthermore, the reflective layer is disposed on the outer wall of the colored pigment layer, and the reflective layer is a composite layer of glass microspheres and resin, with the glass microspheres having a particle size of 20-80 μm.

[0010] Furthermore, the reinforcing layer includes a fiber reinforcement layer disposed on the outer wall of the PVC substrate layer, and the outer wall of the fiber reinforcement layer is provided with a wear-resistant layer to enhance the strength of the PVC substrate layer.

[0011] Furthermore, the fiber reinforcement layer is made of glass fiber cloth and is arranged in a honeycomb pattern.

[0012] Furthermore, the wear-resistant layer is a silicon carbide particle composite layer, and the thickness of the wear-resistant layer is 8-15μm.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This type of color reflective high-strength PVC sheet, by setting a color reflective composite layer, wherein the color pigment layer is made of organic pigments mixed with PVC resin, which can be mixed to produce a rich variety of colors to meet diverse decoration and design needs, and the primer layer is an acrylic resin coating, which can enhance the adhesion to the PVC substrate layer and ensure the color is long-lasting and stable.

[0015] 2. The reflective layer is a composite layer of glass microspheres and resin.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1-6 The present invention provides the following technical solution: a color reflective high-strength PVC sheet, comprising a PVC substrate layer 1, a color reflective composite layer 3 for reflecting colors is disposed on one side of the PVC substrate layer 1, the color reflective composite layer 3 comprising a primer layer 301, a color pigment layer 302 and a reflective layer 303 stacked sequentially, the primer layer 301 is coated on the outer wall of one side of the PVC substrate layer 1, and the primer layer 301 is an acrylic resin coating, and the thickness of the primer layer 301 is 5-10μm, the color pigment layer 302 is disposed on the outer wall of the primer layer 301, and the color pigment layer 302 is a mixture of organic pigment and PVC resin, and the pigment particle size is ≤50μm, the reflective layer 303 is disposed on the outer wall of the color pigment layer 302, and the reflective layer 303 is a composite layer of glass microspheres and resin, and the glass microsphere particle size is 20-80μm.

[0026] The colored reflective composite layer 3 achieves color presentation and light reflection functions through the synergistic effect of its components. The primer layer 301 is a 5-10μm thick acrylic resin coating. Due to its good compatibility with the PVC substrate layer 1, it can form a strong intermolecular force between the two, effectively enhancing the adhesion effect and providing a stable foundation for the upper material. The colored pigment layer 302 is made of organic pigments and PVC resin. During the mixing and coating process, the pigments are uniformly dispersed in the PVC resin. Through a specific color matching process, the PVC sheet is given rich colors. When light shines on it, the pigments selectively absorb and reflect light of different wavelengths, thus presenting the desired color. The outermost reflective layer 303 is made of glass microspheres and resin. It has the characteristics of high refractive index. When light is incident on the surface of the glass microspheres, it will undergo multiple refractions and reflections inside the microspheres and finally be reflected back to the outside at a large angle, which greatly improves the light reflection efficiency of the PVC sheet and meets the requirements of reflective performance in scenarios such as billboards and traffic signs.

[0027] Example 2: Based on Example 1, a reinforcing layer 2 is also disclosed, the specific structure of which is as follows: A reinforcing layer 2 for increasing the strength of the PVC substrate layer 1 is provided on the other side of the PVC substrate layer 1. The reinforcing layer 2 includes a fiber reinforcement layer 201 disposed on the outer wall of the PVC substrate layer 1, and a wear-resistant layer 202 is provided on the outer wall of the fiber reinforcement layer 201 for reinforcing the strength of the PVC substrate layer 1. The wear-resistant layer 202 is a silicon carbide particle composite layer, and the thickness of the wear-resistant layer 202 is 8-15μm.

[0028] The reinforcing layer 2 is composed of a fiber-reinforced layer 201 and a wear-resistant layer 202, which improves the strength and durability of the PVC sheet. The fiber-reinforced layer 201 uses a honeycomb-shaped glass fiber cloth. This structure ensures the material is lightweight while forming an efficient mechanical support network. Glass fiber itself has the characteristics of high strength and high modulus. When the PVC sheet is subjected to external forces such as tension, bending or impact, the glass fiber cloth can effectively disperse stress. With its excellent tensile properties, it can limit the deformation of the sheet and enhance the tensile strength. Its rigid structure can resist bending deformation and improve bending performance. When subjected to impact, the synergistic effect of the fiber and the PVC matrix can absorb impact energy and enhance impact resistance. The outer wear-resistant layer 202 is composed of silicon carbide particles. Silicon carbide has extremely high hardness, and its particles are evenly distributed in the wear-resistant layer 202. When the sheet surface rubs against external objects, the silicon carbide particles can effectively resist abrasive wear, reduce surface material loss, and reduce the coefficient of friction, thereby significantly improving the wear resistance of the sheet and extending its service life in high-friction and high-wear environments.
