Plastic plate or film having super steel wool resistance and weathering resistance, and preparation method thereof

Abstract

The present invention discloses a plastic plate or film having super steel wool resistance and weathering resistance. The plastic plate or film comprises a substrate, a first film layer positioned on the surface f the substrate and having weathering resistance, and a second layer film layer positioned on the surface of the first film layer and having super steel wool resistance and weathering resistance, wherein the second film layer has super steel wool resistance and weathering resistance, and a coating material with characteristics of super steel wool resistance and weathering resistance is coated on both surfaces of the first film layer having weathering resistance through leaching coating, spray coating, immersion coating or roller coating, and ultraviolet light irradiation and curing lamination are sequentially performed to obtain the second film layer. According to the present invention, the plastic plate or film with characteristics of super steel wool resistance and weathering resistance has performances of improved hardening, improved hydrophobicity, improved lipophobicity, improved scale resistance and improved weathering resistance, and can replace the traditional glass product so as to be used in different industries (the windows of vehicles, high-speed rail and subway in the transportation industry), such that the traditional glass products can be replaced, and the advantages of cost reducing, weight reducing, emission reducing and energy consumption reducing can be provided.

Description

technical field [0001] The invention relates to the technical field of plate processing, in particular to a plastic plate or film with super steel wool resistance and weather resistance and a preparation method thereof. Background technique [0002] Glass products used in the construction industry, transportation industry, and 3C industry are gradually being banned by plastic plates or films such as PC, PMMA, and PET. However, these PC, PMMA, PET and other plastic plates or films are required to have certain hardness, wear resistance, water resistance, and anti-fouling properties. And products used outdoors need more weather resistance. The improvement of these properties is generally processed by coating and hard coating, so as to endow special functions and meet application requirements. [0003] It can achieve good hydrophobic, oleophobic, anti-fouling, wear-resistant, and hardening effects after coating. The current solution is to add fluorine additives to the coating....

Problems solved by technology

However, after adding fluorine additives in the coating, although it can give high water contact angle (100 °-108 °) after film formation, good wear resistance (steel wool abrasion resistance test times 50-200 rounds), but The cost of fluorine additives is high, and the compatibility with the system is poor, the stability is poor, and it is easy to cause various restrictions in the process of coating preparation or application, often failing to achieve the best ideal effect

[0004] For the improvement of weather resistance, it is generally by adding some ultraviolet absorbers that can absorb sunlight and ultraviolet rays in fluorescent light sources without changing themselves, so as to avoid long-term exposure to sunlight, but due to the absorption of ultraviolet energy. Oxidation reaction, leading to polymer degradation, which makes the product performance and appearance vulnerable to serious damage
