Technical Field
The embodiment of the invention relates to the technical field of glass fiber reinforced plastic processing, and discloses a method for improving the surface scratch resistance of glass fiber reinforced plastic, an electronic device and a laser marking machine.
Background
Glass Fiber Reinforced Plastic (FRP) is a composite material with various varieties, individual properties and wide application. The glass fiber reinforced plastic is a functional novel material prepared from synthetic resin and glass fiber by a composite process, and has the characteristics of light weight, high specific strength, corrosion resistance, good electrical insulation performance, slow heat transfer, good thermal insulation performance, good instantaneous ultrahigh temperature resistance, easy coloring, permeability of electromagnetic waves and the like. The glass fiber reinforced plastic is widely applied to the related industries such as aerospace, railway, decorative buildings, home furniture, building materials, bathroom and environmental sanitation engineering and the like due to the unique performance advantages. The great rise of electronic products in recent years has led to the widespread use of glass fiber reinforced plastics in electronic products, such as: the mobile phone, the tablet, the smart watch and the like. The glass fiber reinforced plastic has a surface on which tips of the glass fibers protrude (which can be observed under a high power microscope), and the glass fibers have high rigidity, and thus, the glass fibers are broken after a certain pressure is applied, resulting in a difference between the surface roughness of the broken portions and the surface roughness of the other portions of the glass fiber reinforced plastic. Further, the refractive and reflective properties of the glass fiber reinforced plastic may also differ, which is particularly indicated by the strong reflective property at the fracture site, which is different from the colors at other sites. At present, because electronic products are frequently contacted with a human fingernail in the using process, the tips of glass fibers on the surface of the glass fiber reinforced plastic are also easy to break, and surface scratches and color differences occur.
In the process of researching the invention, the inventor finds that the scratch resistance of the surface of the glass fiber reinforced plastic in the prior art is weak, and a relatively simple method for improving the scratch resistance of the surface of the glass fiber reinforced plastic is lacked.
