Abstract
Description
Technical Field
[0001] This application relates to the field of automotive repair, and more particularly to a masking paper for vehicle paint repair. Background Technology
[0002] Masking paper for vehicle paint repair is a protective tool specifically designed for the automotive paint repair process. It's primarily used to cover areas that don't need repair during painting, sanding, or other repair work, preventing paint, dust, or other substances from contaminating the vehicle's surface. It's typically made of waterproof, heat-resistant materials with strong adhesion, ensuring precise operation during the repair process. Masking paper effectively protects windows, headlights, emblems, and other parts from paint contamination, ensuring a smooth repair process. Furthermore, masking paper is usually easy to use and leaves no residue or damage to the original paint after removal, making it an indispensable tool in automotive paint repair and painting.
[0003] Traditional masking paper for vehicle paint repair in existing technologies is usually fixed to the vehicle surface with tape. This masking paper cannot be reused after use and is discarded after one-time use. As a result, new masking paper needs to be purchased for each repair. This not only increases the cost of repair work, but also causes a lot of waste of resources. Because it is not reusable, repair personnel need to change the masking paper frequently. This not only increases labor costs, but may also affect the efficiency and quality of repair. During frequent changes, improper operation may lead to incomplete masking or paper damage, resulting in unexpected paint contamination during painting or repair, affecting the final repair effect. Utility Model Content
[0004] To address the problem that masking paper cannot be reused after use and is discarded after a single use, requiring the purchase of new masking paper for each repair, which not only increases the cost of repair work but also causes a significant waste of resources, and because it is not reusable, repair personnel need to frequently replace the masking paper, which not only increases labor costs but may also affect the efficiency and quality of repair. During frequent replacements, improper operation may lead to incomplete masking or paper damage, resulting in unexpected paint contamination during painting or repair and affecting the final repair effect. This application provides a masking paper for vehicle paint repair.
[0005] The masking paper for vehicle paint repair provided in this application adopts the following technical solution:
[0006] The invention includes a masking paper body for covering unpainted surfaces of a vehicle, the masking paper body including an adhesive film for applying to the vehicle paint, a lower plastic film layer at the upper end of the adhesive film, an upper plastic film layer at the upper end of the lower plastic film layer, a tensile mesh between the lower plastic film layers, and kraft paper at the upper end of the upper plastic film layer.
[0007] Preferably, the tensile mesh is pressed between the lower plastic film layer and the upper plastic film layer by a hot pressing process.
[0008] Preferably, the kraft paper is bonded to the upper end of the upper plastic film layer by an adhesive process.
[0009] Preferably, the adhesive film is pressed together with the lower plastic film layer by a hot-pressing process.
[0010] Preferably, both the lower and upper plastic film layers are made of polytetrafluoroethylene, and the tensile mesh is made of polypropylene.
[0011] In summary, this application includes at least one of the following beneficial technical effects:
[0012] The working principle of the masking paper relies on the functional synergy of each material layer. First, the film is directly applied to the vehicle surface, forming good adhesion with the paint. When using it, spray an appropriate amount of water on the area of the vehicle to be masked. With the help of water, the film can adhere more firmly to the paint surface, effectively preventing the masking paper from falling off. The use of moisture increases the adhesion of the film layers, ensuring that the masking paper stably covers the paint surface during the repair process, avoiding the problem of falling off due to external forces. The tensile mesh between the upper and lower plastic film layers enhances the durability and tensile strength of the masking paper.
[0013] The kraft paper, located on top of the upper plastic film layer, is primarily used to enhance the shaping ability of the masking paper, ensuring that it can smoothly cover the curved surface of the vehicle and maintain its shape during use without easily deforming. This structure improves the adaptability of the masking paper, allowing it to easily adapt to various vehicle body shapes and further enhancing the masking effect. This masking paper not only provides effective protection during the repair process but also features reusability, effectively solving potential durability and compatibility issues during the repair process.

[0017] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.
[0018] This application discloses a masking paper for vehicle paint repair, including a masking paper body 1 for masking the surface of the vehicle that does not need to be painted. The masking paper body 1 includes an adhesive film 101 for applying to the vehicle paint. A lower plastic film layer 102 is provided at the upper end of the adhesive film 101, and an upper plastic film layer 104 is provided at the upper end of the lower plastic film layer 102. An anti-tensile mesh 103 is provided between the lower plastic film layer 102 and the upper plastic film layer 104. Kraft paper 105 is provided at the upper end of the upper plastic film layer 104. The working principle of the masking paper body 1 relies on the functional synergy of the various material layers. First, the adhesive film 101 is directly adhered to the vehicle surface, forming good adhesion with the paint. When using it, an appropriate amount of water is sprayed on the area of the vehicle that needs to be masked. With the help of water, the adhesive film 101 can adhere more firmly to the paint surface, effectively preventing the masking paper from being damaged. The use of moisture increases the adhesion of the film layer, ensuring that the masking paper stably covers the paint surface during the repair process, avoiding the problem of peeling off due to external forces. The tensile mesh 103 between the upper plastic film layer 104 and the lower plastic film layer 102 enhances the durability and tensile strength of the masking paper. The kraft paper 105 is located at the top of the upper plastic film layer 104 and is mainly used to enhance the shaping ability of the masking paper, ensuring that the masking paper can smoothly cover the curved surface of the vehicle and maintain its shape during use without deformation. This structure improves the adaptability of the masking paper, making it easy to adapt to various body shapes and further enhancing the masking effect. This masking paper not only plays an effective protective role during the repair process, but also has the characteristic of being reusable, effectively solving the durability and compatibility problems that may exist during the repair process.
[0019] Reference Figure 2Tensile mesh 103 is pressed between the lower plastic film layer 102 and the upper plastic film layer 104 using a hot-pressing process. Kraft paper 105 is adhered to the upper end of the upper plastic film layer 104 using an adhesive process. Adhesive film 101 is pressed together with the lower plastic film layer 102 using a hot-pressing process. Both the lower and upper plastic film layers 102 are made of polytetrafluoroethylene (PTFE), while the tensile mesh 103 is made of polypropylene. PTFE has extremely low surface energy and excellent chemical stability, effectively resisting organic solvents, strong acids, and strong alkalis used in the repair process. The corrosion from chemical substances ensures the stability of the masking paper under high temperature and chemical environments, while the tensile strength of the polypropylene 103 mesh provides sufficient strength and durability. Its excellent flexibility ensures that it is not easily broken or deformed during use. Especially in low temperature environments, polypropylene has strong toughness, is not easily brittle, and can withstand greater tensile forces. This allows the masking paper to work stably in harsh environments, ensuring its reliability in long-term use. This masking paper not only plays an effective protective role in the repair process, but also has the characteristic of being reusable, effectively solving the durability and compatibility problems that may exist in the repair process.
