A kind of automobile safety glass and its production process

Abstract

An automobile safety glass and a production process thereof relate to the technical field of automobile glass. The automobile safety glass comprises a glass body, a heating wire, a high temperature resistance seal head and an electrical contact. The production process comprises the following steps of raw material selection, mixing and stirring, melting, molding, annealing, softening, uniform cooling, cutting and trimming. After the formed raw material is in a liquid state, a glass liquid of 1135 to 1140 DEG C is dropped into a molding die from 160 to 170 mm height, and the molding die is provided with a cooling system. When the glass liquid of 1030 to 1050 DEG C enters the molding die, the glass temperature is from 1000 to 1020 DEG C at the upper part of the glass liquid at a distance of 130 to 40 mm from the front end of the molding die, and the assembled heating wire, the high temperature resistance seal head and the electric contact are horizontally immersed in the glass liquid and then cooled. The structure is simple, the usage is convenient, the automobile safety glass can be heated and broken in emergency, the safety is high, the production process is simple and easy to control, and the heating wire can be accurately pre-buried in the glass.

Description

Technical field: [0001] The invention relates to the technical field of automobile glass, in particular to an automobile safety glass and a production process thereof. Background technique: [0002] Existing automotive glass generally uses tempered glass, which has high hardness and strong impact resistance. It cannot be broken immediately in an emergency. At this stage, most of them are safety hammers. The popularity rate of safety hammers is not high, and safety hammers It is laborious to operate, and the correct method must be mastered. In an emergency, and the thoughts of the members may be affected, often the people in the car cannot escape in time. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the existing technical defects, and provide an automobile safety glass that can be heated and broken in an emergency, has high safety, and a simple and easy-to-control production process and its production process.
