Application of plexiglass processing in new energy
compared plexiglass with traditional inorganic glass, analyzed the development status of plexiglass processing and the performance characteristics of plexiglass processing, and introduced the processing of plexiglass in new energy vehicles. Glass processing was measured. The results show that, except for polycarbonate glass, the abrasion resistance of organic glass and inorganic glass meets ECER43 'Uniform Provisions on Certification of Safety Glass MaterialsIt can enhance the wear resistance of the glass material, but has little effect on its strength; the average weighted sound insulation in the car using plexiglass as the window material is lower than that of inorganic glass, and in the low frequency range that human ears can hear, organic The sound insulation performance of glass is better.
New energy vehicles refer to vehicles with new technologies and new structures that use new energy sources as power sources and combine advanced technologies such as drive control.
Polymethyl methacrylate (PMMA), commonly known as plexiglass, is a recyclable thermoplastic engineering plastic with low density (1.15-1.19g/cm3), High mechanical strength, low melting point (130-140℃), high light transmittance, easy processing, etc. The use of PMMA and its composite materials as automobile body and parts materials, including side triangular windows, lampshades, bumpers, etc., can effectively reduce the weight of the automobile and achieve the purpose of reducing energy consumption and exhaust emissions.
Based on the energy-saving and environmental protection needs of new energy vehicles, combined with the processing of plexiglass on auto parts, taking automobile side windows as an example, the application and performance of plexiglass processing in new energy vehicles are discussed.
Automobile windows can be divided into sandwich type and tempered type according to their structure, and can be divided into front, side, rear windshield and sunroof glass according to their position. In order to create a good driving vision and driving safety environment, car window glass should generally meet the requirements of light transmission, impact resistance, weather resistance and less debris. Plexiglass not only satisfies the above requirements well, but also has the effect of anti-ultraviolet radiation, avoiding the long-term exposure of the people in the car. On the other hand, the good optical properties of plexiglass materials can be used to make a car cover, which protects the entire body from ultraviolet rays and does not affect the driving vision.
In addition to window glass, the processing of plexiglass in new energy vehicles also includes other automobile accessories, such as taillight lampshades, high-gloss decorations, and automobile bumpers. Plexiglass materials are widely used in new energy vehicle taillight lampshades because of their light weight, easy coloring, and beautiful appearance; because of their anti-scratch, high surface gloss, and high hardness, they are widely used in high-gloss decorations of new energy vehicles. . In addition, PMMA/ABS composite material made by blending plexiglass and acrylonitrile-butadiene-styrene copolymer (ABS) can be used to manufacture new energy vehicle bumpers. The composite material also has the impact resistance and resistance of ABS. It has the advantages of good temperature, good electrical properties, easy spraying, and the advantages of plexiglass, such as scratch resistance, non-fading, and environmental protection. It is suitable as a product with high quality requirements, and the cost is lower than that of magnesium aluminum alloy and other materials.
