Abstract
Description
Technical Field
[0001] This utility model belongs to the field of PVC coating technology, specifically relating to a scratch-resistant PVC coating for automobiles. Background Technology
[0002] PVC-coated skin is a surface covering layer with polyvinyl chloride (PVC) as the core material. It is combined with the substrate through a specific process and is widely used in decoration, automotive and protection fields.
[0003] Existing automotive PVC-coated surfaces have poor scratch resistance. When PVC-coated surfaces are subjected to pressure from hard objects, the friction between the PVC-coated surfaces and the hard objects increases instantaneously. As the hard objects move, they easily scratch the PVC-coated surfaces, causing wear and scratches.
[0004] Therefore, a scratch-resistant PVC coating for automotive applications is proposed. Summary of the Invention
[0005] This invention provides a scratch-resistant PVC coating for automotive applications, with the aim of solving the aforementioned problems.
[0006] This utility model provides a scratch-resistant automotive PVC coating, comprising an upper PVC substrate layer and a lower PVC substrate layer, the upper PVC substrate layer being located below the lower PVC substrate layer; an ABS resin layer disposed on top of the upper PVC substrate layer; an elastic sleeve and an elastic pull strip disposed between the upper PVC substrate layer and the lower PVC substrate layer, the elastic pull strip being located inside the elastic sleeve; limiting holes respectively penetrating the top of the upper PVC substrate layer and the lower PVC substrate layer; pull strip caps respectively disposed at the top and bottom of the elastic pull strip, the elastic pull strip penetrating through the limiting holes; a graphene coating coated on top of the ABS resin layer; and an adhesive layer disposed at the bottom of the lower PVC substrate layer.
[0007] Furthermore, a total of eight elastic tension bars are provided, and the eight elastic tension bars are distributed at equal intervals along the same vertical axial direction, and the elastic tension bars are set in an inclined state;
[0008] By adopting the above technical solution, eight inclined elastic strips can form a multi-directional buffer elastic layer between the upper PVC substrate layer and the lower PVC substrate layer, avoiding the problem of displacement caused by increased misalignment force between the upper PVC substrate layer and the lower PVC substrate layer when the upper PVC substrate layer is subjected to inclined scratching force.
[0009] Furthermore, both the pull tab cap and the limiting hole have circular cross-sections, and the outer diameter of the pull tab cap is larger than the inner diameter of the limiting hole;
[0010] By adopting the above technical solution, the pull cap 7 is prevented from passing through the limiting hole, thus ensuring the stability of the elastic pull strip.
[0011] Furthermore, an elongated groove is formed on the top of the ABS resin layer;
[0012] By adopting the above technical solution, the long groove can increase the contact area with the graphene coating, making it easier for the graphene coating to be firmly coated on the ABS resin layer.
[0013] Furthermore, the elastic sleeve is made of rubber, and the elastic pull strip is made of rubber.
[0014] By adopting the above technical solution, the elastic deformation capability of the elastic sleeve and elastic strip is guaranteed.
[0015] The beneficial effects of this utility model are as follows:
[0016] This invention utilizes elastic strips arranged in multiple crisscrossing directions to provide a rebound buffer when the upper and lower PVC substrate layers are subjected to shear force. By stretching and deforming the elastic strips in the direction of the inclined scraping force, the rebound force of the elastic strips buffers the scraping force, pulling the misaligned parts of the upper and lower PVC substrate layers back into place. This reduces the scraping force directly received by the PVC coating skin, avoids hard contact, improves the protection of the PVC coating skin, and thus reduces damage caused by scratches.
[0017] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0025] Reference Figure 1-4This utility model provides a scratch-resistant automotive PVC coating, comprising an upper PVC substrate layer 1 and a lower PVC substrate layer 2. The upper PVC substrate layer 1 is located below the lower PVC substrate layer 2, and an ABS resin layer 3 is disposed on top of the upper PVC substrate layer 1. An elongated groove is formed on the top of the ABS resin layer 3, which increases the contact area with the graphene coating 8, facilitating the firm coating of the graphene coating 8 onto the ABS resin layer 3. An elastic sleeve 4 is disposed between the upper PVC substrate layer 1 and the lower PVC substrate layer 2, and eight elastic pull strips 5 are disposed near the inner side of the elastic sleeve 4 between the upper PVC substrate layer 1 and the lower PVC substrate layer 2. These eight elastic pull strips 5 are evenly spaced along the same vertical axial direction and are arranged at an angle. These eight angled elastic pull strips 5 form a multi-directional buffer elastic layer between the upper PVC substrate layer 1 and the lower PVC substrate layer 2, preventing the upper PVC substrate layer from slipping. When the VC matrix layer 1 is subjected to an inclined scratching force, the misalignment force between the upper PVC matrix layer 1 and the lower PVC matrix layer 2 increases, causing displacement. The elastic sleeve 4 is made of rubber, and the elastic pull strip 5 is made of rubber to ensure the elastic deformation capability of the elastic sleeve 4 and the elastic pull strip 5. The top of both the upper PVC matrix layer 1 and the lower PVC matrix layer 2 are provided with limiting holes 6 through which the elastic pull strip 5 can pass. One end of the elastic pull strip 5 is provided near the upper PVC matrix layer 1, and the other end of the elastic pull strip 5 is provided near the lower PVC matrix layer 2. The cross-section of the pull strip cap 7 and the limiting hole 6 are both circular, and the outer diameter of the pull strip cap 7 is larger than the inner diameter of the limiting hole 6 to prevent the pull strip cap 7 from passing through the limiting hole 6 and to ensure the stability of the elastic pull strip 5. The top of the ABS resin layer 3 is provided with a graphene coating 8. The graphene coating 8 can reduce the coefficient of friction and form a smooth surface, reducing the direct effect of external forces on the coating skin. The bottom of the lower PVC matrix layer 2 is provided with an adhesive layer 9.
[0026] The specific implementation method is as follows: In use, the PVC-coated skin is first bonded and fixed to the automotive parts using the adhesive layer 9. When the PVC-coated skin is scratched, since the scratching force is not always perpendicular to the PVC-coated skin, when the PVC-coated skin is locally subjected to an inclined scratching force, a shear force is generated between the upper PVC substrate layer 1 and the lower PVC substrate layer 2 under the action of the scratching force. The elastic sleeve 4 adapts to the inclined bending deformation, and the elastic pull strip 5 in the direction of the scratching force is stretched. The rebound force of the elastic pull strip 5 is used to buffer the scratching force and pull the misaligned part of the upper PVC substrate layer 1 and the lower PVC substrate layer 2 back into place, reducing the scratching force directly received by the PVC-coated skin, avoiding hard contact, and improving the protective effect of the PVC-coated skin.
[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
