Problems solved by technology

However, in actual use, on the one hand, the windshield has the risk of being accidentally scratched by external hard substances, such as thick branches or other sharp objects rubbed against during driving; The friction of the wiper, although it cannot be seen that the wiper has a great risk of scratching the windshield in a short period of time, but from a long-term observation, the windshield of a car that has been used for a long time will be damaged by the long-term friction of the wiper. The glass surface is blurred and there are shallow scratches on the face, which not only affects the aesthetic effect of the car, but also causes the driver's vision to be blurred, which is not conducive to driving safety

Abstract

The invention provides an anti-scratch automobile windshield. The anti-scratch automobile windshield is characterized by being prepared from components in percentage by mass as follows: 40%-50% of SiO2, 25%-30% of Cr2C3, 15%-18% of WC, 5%-8% of Si3N4, 3%-8% of Y2O3, 1%-2% of ZrO2 and 1%-2% of Al2O3, and the sum of the components in percentage by mass is 100%. According to the automobile windshield, 40%-50% of SiO2, 25%-30% of Cr2C3, 15%-18% of WC, 5%-8% of Si3N4, 3%-8% of Y2O3, 1%-2% of ZrO2 and 1%-2% of Al2O3 are selected as the components, a ratio of the components is reasonably allocated, so that the prepared windshield has higher mechanical strength and anti-scratch performance, and compared with traditional resin substrates, scratch cannot be formed on the glass surface easily, and the distinguishing degree is higher.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to an anti-scratch automobile windshield. Background technique [0002] Automobile windshields are usually required to have better clarity, material strength and hardness, so as to better protect the occupants in the car. However, in actual use, on the one hand, the windshield has the risk of being accidentally scratched by external hard substances, such as thick branches or other sharp objects rubbed against during driving; The friction of the wiper, although it cannot be seen that the wiper has a great risk of scratching the windshield in a short period of time, but from a long-term observation, the windshield of a car that has been used for a long time will be damaged by the long-term friction of the wiper. The glass surface is blurred and there are superficial scratches on the face, which not only affects the aesthetic effect of the car, but also causes the driver's vision to...
