Description

Technical Field

[0001] The utility model relates to the technical field of paint films, in particular to an anti-ultraviolet paint film. Background Art

[0002] With global warming and increasing energy shortages, as well as the widespread use of glass in the construction or automotive industries, functional protective films such as heat insulation, UV protection, explosion-proof, and energy-saving protective films are increasingly attracting people's attention. In recent years, due to the continuous destruction of the ozone layer, the amount of ultraviolet radiation reaching the earth has continued to increase, affecting human health while also affecting the use of the coating. Therefore, anti-ultraviolet paint films came into being.

[0003] Among them, the paint film, also known as the coating film, is a solid continuous film, usually composed of multiple layers of coating to prevent the coated object from being corroded by the external environment. In addition, the paint film is thicker and has better chemical stability and mechanical corrosion resistance, but the paint film has a lower hardness and is easily scratched and damaged, which can easily cause the film layer to age.

[0004] Most of the existing anti-ultraviolet paint films cannot effectively prevent ultraviolet rays, resulting in poor durability of the paint films. Utility Model Content

[0005] The utility model aims to provide an anti-ultraviolet paint film, by respectively arranging a wear-resistant layer and a protective layer on the outside of the anti-ultraviolet layer, so as to protect the surface of the anti-ultraviolet layer; the wear-resistant layer is arranged on the outside of the protective layer, which increases the hardness of the paint film while avoiding the aging phenomenon, thereby extending the service life of the paint film; at the same time, when sunlight irradiates on the surface of the paint film, the anti-ultraviolet layer can block the ultraviolet rays in the light; by arranging the filling layer and the absorption layer, the anti-ultraviolet performance of the paint film is further improved, and the durability of the paint film is improved.

[0006] To achieve the above-mentioned purpose, the utility model provides an anti-ultraviolet paint film, including a base layer and a wear-resistant layer arranged above the base layer, a protective layer and an anti-ultraviolet layer are arranged between the base layer and the wear-resistant layer from top to bottom, and a filling layer and an absorption layer are respectively arranged at the position of the anti-ultraviolet layer.

[0007] Preferably, the protective layer is arranged between the wear-resistant layer and the anti-ultraviolet layer, the protective layer is a transparent structural layer, and the wear-resistant layer is made of TPU or PU.

[0008] Preferably, the outer surface of the anti-ultraviolet layer is covered with an ultraviolet reflecting layer, and the interior of the anti-ultraviolet layer is hollow.

[0009] Preferably, the filling layer is arranged at a hollow position inside the anti-ultraviolet layer, and the interior of the filling layer is filled with anti-ultraviolet material.

[0010] Preferably, the absorption layer is further arranged at the hollow position inside the anti-ultraviolet layer. The absorption layer is arranged below the filling layer and is composed of an ultraviolet absorber.

[0011] Preferably, the thickness of the absorption layer is greater than the thickness of the filling layer.

[0012] Preferably, the thickness of the protective layer is smaller than the thickness of the wear-resistant layer.

[0013] Therefore, the utility model adopts the above-mentioned anti-ultraviolet paint film, and respectively arranges a wear-resistant layer and a protective layer on the outside of the anti-ultraviolet layer to protect the surface of the anti-ultraviolet layer. The wear-resistant layer is arranged on the outside of the protective layer, which increases the hardness of the paint film while avoiding aging, thereby extending the service life of the paint film. At the same time, when sunlight shines on the surface of the paint film, the anti-ultraviolet layer can block the ultraviolet rays in the light. By arranging the filling layer and the absorption layer, the anti-ultraviolet performance of the paint film is further improved, and the durability of the paint film is improved.

[0020] Embodiment 1

[0021] like Figure 1 As shown, this embodiment provides an anti-ultraviolet paint film, including a base layer 1 and a wear-resistant layer 2 arranged on the base layer 1, the wear-resistant layer is made of TPU or PU, and the base layer is a common paint, which is in direct contact with the coated object. Among them, a protective layer 3 and an anti-ultraviolet layer 4 are arranged in sequence from top to bottom between the base layer 1 and the wear-resistant layer 2, and a filling layer 42 and an absorption layer 43 are respectively arranged at the position of the anti-ultraviolet layer 4.

[0022] In addition, the protective layer 3 is arranged between the wear-resistant layer 2 and the anti-ultraviolet layer 4. The thickness of the protective layer 3 is less than the thickness of the wear-resistant layer 2. The protective layer 3 is a transparent structural layer, which is used to protect the anti-ultraviolet layer 4 to avoid damage to the wear-resistant layer 2 in a long-term state, causing the external environment to erode the anti-ultraviolet layer 4.

[0023] The outer surface of the anti-ultraviolet layer 4 is coated with an ultraviolet reflection layer 41 for reflecting ultraviolet rays in the sunlight, and the interior of the anti-ultraviolet layer 4 is hollow, and a filling layer 42 is arranged at the hollow position inside the anti-ultraviolet layer 4, and the interior of the filling layer 42 is filled with an anti-ultraviolet material for secondary resistance to residual ultraviolet rays in the light. Among them, the anti-ultraviolet material includes one or more of an inorganic anti-ultraviolet agent, an organic anti-ultraviolet agent and a filler, the inorganic anti-ultraviolet agent is a combination of carbon dioxide, zinc oxide and cerium oxide, the organic anti-ultraviolet agent is a combination of gallic acid and triazine compounds, and the filler is hydrotalcite. In addition, an absorption layer 43 is also arranged at the hollow position inside the anti-ultraviolet layer 4, and the absorption layer 43 is arranged below the filling layer 42, which is composed of an ultraviolet absorber, and the thickness of the absorption layer 43 is greater than the thickness of the filling layer 42, and is used to absorb the ultraviolet rays remaining after reflection in the sunlight, so as to further improve the anti-ultraviolet ability of the paint film.

[0024] Therefore, the utility model adopts the above-mentioned anti-ultraviolet paint film, and respectively arranges a wear-resistant layer and a protective layer on the outside of the anti-ultraviolet layer to protect the surface of the anti-ultraviolet layer. The wear-resistant layer is arranged on the outside of the protective layer, which increases the hardness of the paint film while avoiding aging, thereby extending the service life of the paint film. At the same time, when sunlight shines on the surface of the paint film, the anti-ultraviolet layer can block the ultraviolet rays in the light. By arranging the filling layer and the absorption layer, the anti-ultraviolet performance of the paint film is further improved, and the durability of the paint film is improved.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
