Description

Technical Field

[0001] The utility model relates to the technical field of wall protection films, in particular to a wall protection film used for protecting an original decorative layer. Background Art

[0002] At present, in the interior decoration and building materials industry, especially in the decoration / renovation of old (dilapidated) houses, in order to prevent the building materials from scratching, polluting and wearing the wall decoration layer during the transportation, processing, storage, installation and use, when renovating old houses, a layer of wall PE protective film for protecting the wall decoration layer is usually pasted on the surface of the wall decoration layer to provide stage protection for the wall decoration layer when goods enter and leave.

[0003] However, the existing wall protection film in the form of PE protective film for walls has a single protective film with a tape on the top. The tape has an unstable viscosity, which makes it very easy for workers to damage the original decorative layer when removing the protection. When it is torn off, it is easy to leave difficult-to-remove glue marks, damaging the original decorative layer. Insufficient viscosity cannot firmly fix the protective film, which is easy to fall off during construction and loses its protective effect. In addition, sticking tape on the top of the protective film requires a lot of labor to ensure the quality of the tape sticking, which increases the difficulty of construction and reduces construction efficiency.

[0004] Therefore, the utility model proposes a wall protection film for protecting the original decorative layer to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a wall protection film for protecting the original decorative layer, so as to solve the problem in the prior art that a lot of labor is required to stick the tape on the top of the wall protection film by oneself, and the original decorative layer is easily damaged when the protective film is removed.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A wall protection film for protecting an original decorative layer comprises a heat-reducing adhesive layer, a PE electrostatic adsorption layer and a reinforced high-toughness PET release layer, wherein the PE electrostatic adsorption layer is attached to 1 / 2 of the bottom surface of the reinforced high-toughness PET release layer, and the heat-reducing adhesive layer is attached to the bottom surface of the reinforced high-toughness PET release layer; the heat-reducing adhesive layer is an acrylic-based adhesive; and the PE electrostatic adsorption layer is made of PE material.

[0008] By adopting the above technical solution, the protective film can be directly attached to the wall without the need for tape sticking, which greatly shortens the construction time. At the same time, it can effectively prevent the building materials from scratching, polluting and wearing the wall decoration layer during transportation, processing, storage, installation and use. At the same time, by utilizing the heat-reducing adhesive layer, when the wall protection measures are removed, heating is used to inactivate the heat-reducing adhesive layer, causing the protection to fall off, thereby protecting the wall decoration layer from damage.

[0009] Furthermore, a plurality of tear ears are evenly arranged at the end of the reinforced high-toughness PET release layer away from the PE electrostatic adsorption layer.

[0010] By adopting the above technical solution, it is easy to peel off the PET release layer, avoiding damage to the original wall decoration layer during the process of tearing off the PET release layer.

[0011] Furthermore, the PE electrostatic adsorption layer is attached to the bottom 1 / 2 of the reinforced high-toughness PET release layer through a thermal viscosity-reducing adhesive layer.

[0012] By adopting the above technical solution, the reinforced high-toughness PET release layer on the PE electrostatic adsorption layer can be peeled off by auxiliary heating with a hot air blower / heating equipment, so that the thermal viscosity-reducing adhesive layer loses its activity, and the failure temperature of the PE electrostatic adsorption layer is much higher than that of the thermal viscosity-reducing adhesive layer, so the PE electrostatic adsorption layer can be reused.

[0013] Furthermore, the thickness of the PE electrostatic adsorption layer is greater than or equal to 0.1 mm.

[0014] By adopting the above technical solution, the electrostatic adsorption force of the PE electrostatic adsorption layer can be improved, and the PE electrostatic adsorption layer can have sufficient strength while ensuring its flexibility, thereby ensuring that the wall decoration layer is not damaged.

[0015] Furthermore, the thickness of the thermally debonding adhesive layer is greater than or equal to 0.5 mm.

[0016] By adopting the above technical solution, the adhesion ability and weather resistance of the thermal anti-viscosity adhesive layer can be enhanced, and the influence of environmental factors on the thermal anti-viscosity adhesive layer can be reduced.

[0017] Furthermore, the thermal viscosity-reducing adhesive layer, the PE electrostatic adsorption layer and the reinforced high-toughness PET release layer are all wound along the support shaft.

[0018] By adopting the above technical solution, the protective film can be supported, which facilitates the storage and transportation of the protective film.

[0019] Furthermore, a positioning groove is formed through the inner wall of the support shaft along the axial direction.

[0020] By adopting the above technical solution, the support shaft can be quickly positioned when being installed and connected with the corresponding rotating shaft, so that the protective film can be slowly unfolded from the support shaft.

[0021] In summary, compared with the prior art, the utility model has the following beneficial effects:

[0022] 1. The utility model strengthens the high-toughness PET release layer and the heat-reducing adhesive layer and the PE electrostatic adsorption layer by bonding and fixing the heat-reducing adhesive layer with the wall decoration layer, and can directly attach the protective film to the wall without the need for tape pasting, which greatly shortens the construction time. At the same time, it can effectively prevent the building materials from scratching, polluting and wearing the wall decoration layer during transportation, processing, storage, installation and use. At the same time, by using the heat-reducing adhesive layer, when the wall protection measures are removed, the heat-reducing adhesive layer is inactivated by heating to cause the protection to fall off, thereby ensuring that the wall decoration layer is not damaged. At the same time, the PE electrostatic adsorption layer is used to ensure that it is not easily damaged during protection, which improves the wall protection effect during decoration and renovation.

[0023] 2. The utility model can tear off the reinforced high-toughness PET release layer that is released from the wall by evenly disposing a plurality of tearing ears at the end of the reinforced high-toughness PET release layer away from the PE electrostatic adsorption layer, thereby avoiding damage to the original wall decoration layer during the tearing and peeling process.

[0027] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In this application, the directions or positional relationships indicated by the terms "upper", "inner", "outer", "middle", etc. are based on the directions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0029] like Figure 1 As shown, a wall protection film for protecting the original decorative layer includes a thermal anti-sticking adhesive layer 1, a PE electrostatic adsorption layer 2 and a reinforced high-toughness PET release layer 3, wherein the PE electrostatic adsorption layer 2 is attached to 1 / 2 of the bottom surface of the reinforced high-toughness PET release layer 3, and the PE electrostatic adsorption layer 2 is attached to 1 / 2 of the bottom surface of the reinforced high-toughness PET release layer 3 through the thermal anti-sticking adhesive layer 1; and then a hot air blower / heating equipment can be used to assist in heating to peel off the reinforced high-toughness PET release layer 3 on the PE electrostatic adsorption layer 2, so that the thermal anti-sticking adhesive layer 1 loses its activity, and the failure temperature of the PE electrostatic adsorption layer 2 is much higher than that of the thermal anti-sticking adhesive layer 1, so that the PE electrostatic adsorption layer 2 can be reused for a second time. The thermal anti-adhesive layer 1 is attached to the bottom surface of the reinforced high-toughness PET release layer 3; and then the reinforced high-toughness PET release layer 3 is bonded and combined with the thermal anti-adhesive layer 1 and the PE electrostatic adsorption layer 2, and the thermal anti-adhesive layer 1 is bonded and fixed to the wall decoration layer, so that the protective film can be directly attached to the wall without the need for tape pasting, which greatly shortens the construction time and can effectively prevent the building materials from scratching, polluting and wearing the wall decoration layer during transportation, processing, storage, installation and use. At the same time, by utilizing the thermal anti-adhesive layer 1, when the wall protection measures are removed, heating is used to inactivate the thermal anti-adhesive layer 1, resulting in the protection falling off, thereby ensuring that the wall decoration layer is not damaged.

[0030] The heat-reducing adhesive layer 1 is an acrylic-based adhesive; the acrylic-based adhesive has a moderate initial viscosity, which is convenient for adjusting the protective film during initial positioning, can provide stable adhesion during installation, and can be deactivated by heating when it needs to be removed, thereby losing its viscosity, thus avoiding damage to the wall decoration layer. The PE electrostatic adsorption layer 2 is made of PE material. It can be closely attached to the wall through static electricity, which enhances the adhesion and stability of the protective film, prevents the protective film from falling off during work, and improves the wall protection effect during decoration.

[0031] The end of the reinforced high-toughness PET release layer 3 away from the PE electrostatic adsorption layer 2 is evenly provided with a plurality of tearing ears 7. Then, one end of the reinforced high-toughness PET release layer 3 is gently pulled up by the tearing ears 7 on the reinforced high-toughness PET release layer 3, and then it is slowly and steadily peeled off along the wall surface. During the peeling process, a hot air blower / heating equipment is used for auxiliary heating, so that the heat-reducing adhesive layer 1 loses its activity and the viscosity gradually disappears, thereby avoiding damage to the original wall decoration layer during the tearing and peeling process.

[0032] The heat-reducing adhesive layer 1, the PE electrostatic adsorption layer 2 and the reinforced high-toughness PET release layer 3 are all wound along the support shaft 5, thereby supporting the protective film and facilitating the storage and transportation of the protective film. A positioning groove 6 is provided through the inner wall of the support shaft 5 along the axial direction. The positioning groove 6 can be quickly positioned when the support shaft 5 is installed and connected to the corresponding rotating shaft, so that the protective film can be slowly unfolded from the support shaft 5.

[0033] like Figure 2 As shown, the thickness of the thermal anti-adhesive layer 1 is greater than or equal to 0.5 mm, thereby enhancing the adhesion and weather resistance of the thermal anti-adhesive layer 1 and reducing the impact of environmental factors on the thermal anti-adhesive layer 1. The thickness of the PE electrostatic adsorption layer 2 is greater than or equal to 0.1 mm, thereby improving the electrostatic adsorption force of the PE electrostatic adsorption layer 2, ensuring the flexibility of the PE electrostatic adsorption layer 2 while having sufficient strength, thereby ensuring that the wall decoration layer is not damaged.

[0034] The working process of the utility model is:

[0035] First, clamp the support shaft 5 with the corresponding rotating shaft, align one end of the protective film with the starting position of the wall, press gently to make the heat-reducing adhesive layer 1 initially contact with the wall, and then slowly unfold the protective film from the support shaft 5 to ensure that the heat-reducing adhesive layer 1, the PE electrostatic adsorption layer 2 and the reinforced high-toughness PET release layer 3 are all kept flat. Use a scraper to apply force evenly from one end of the protective film to the other end to eliminate air bubbles between the protective film and the wall to ensure that the protective film is fully fitted.

[0036] When the protective film needs to be removed, firstly, one end of the reinforced high-toughness PET release layer 3 is gently pulled up by the tearing ears 7 on the reinforced high-toughness PET release layer 3, and then it is slowly and steadily peeled off along the wall surface. During the peeling process, a hot air blower / heating device is used to assist in heating, so that the thermal viscosity-reducing adhesive layer 1 loses its activity and the viscosity gradually disappears.
