Abstract

The invention belongs to the technical field of automobile glass, and discloses tempered glass for a side window of an automobile. The tempered glass for the side window of the automobile disclosed by the invention is placed into a mixed salt of KNO3, K2CO3 and diatomite for chemical tempering. The chemically-tempered high-alumina high-silicon glass is prepared from the following components in percentage by mass: 57.8 to 65.5 percent of SiO2, 8.8 to 13.8 percent of Al2O3, 9.2 to 14.2 percent of Na2O, 2.2 to 5.8 percent of K2O, 5.2 to 8.8 percent of MgO, and 0.0 to 0.2 percent of CaO. By adopting the tempered glass, the overall mass of an automobile body is reduced, the oil consumption of the automobile is lowered in a driving process, and a certain energy-saving effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of automobile glass and discloses a tempered glass used for automobile side windows. Background technique [0002] According to regulations, the safety glass used in automobiles is generally divided into windshield glass (front windshield glass) and glass other than the windshield (glass other than the front windshield); automotive safety glass is generally divided into laminated glass, tempered glass according to the processing technology. Glass, plastic glass; according to the national standard "GB9656-2003 Automobile Safety Glass", the front windshield (windshield glass, windshield glass) of the car usually adopts laminated glass; this laminated glass is composed of two layers of glass Clip PVB (polyvinylbutyral, Polyvinylbutyral) is made by hot melting. The shape of the windshield glass is designed according to the shape of the car; the side window glass of the car (including the door, corner window, re...
