Abstract

The invention discloses an aeronautic glass formula. The aeronautic glass formula comprises the raw material components: in percent by mass, 55-65% of SiO2, 15-25% of Al2O3, 10-15% of Na2O, 1-5% of Li2O, 1-5% of MgO, 1-3% of K2O, 1-3% of P2O5, 0.5-3% of Bi2O, 0.5-2% of TiO2 and 0.05-0.3% of Cl2, uniform mixing is performed, and melting is performed in a smelting furnace at a temperature of 1600-1650 DEG C. Meanwhile, the invention discloses a preparation method of the aeronautic glass. The preparation method comprises the following steps: (1) weighing the raw materials accurately, (2), introducing SiO2 by using ultra-white quartz sand, introducing Na2O by using soda ash and sodium chloride, introducing MgO by using heavy magnesium carbonate, and performing mixing with Al2O3 powder, Li2O powder, P2O5 powder, Bi2O powder and TiO2 powder, and performing uniform stirring; and (3), putting the mixture obtained in the step (2) into a glass melting furnace; and (4) completing annealing and molding in an annealing furnace. The formula is reasonable, the whole quality, mechanical strength and chemical stability of the glass can be ensured, and enlargement of the application range of the glass is facilitated; and meanwhile, the processing method is beneficial to improvement of the processing efficiency.

Description

technical field [0001] The invention belongs to the technical field of aviation glass, and in particular relates to a formula and a preparation method of aviation glass. Background technique [0002] Aviation glass refers to the windshield glass in front of the pilot and navigator, the bulletproof glass on the tail turret of the aircraft and the window glass of the camera cabin of the aerial survey aircraft, etc. Aviation glass is an important component to ensure the safety of the aircraft, so its strength has been raised. At the same time, it is necessary to consider the impact of the weight of the glass on the energy consumption of the aircraft, and it is necessary to choose a glass with a smaller weight under the same strength; at present, aviation glass is divided into two categories: aviation plexiglass and aviation inorganic glass. Aviation plexiglass has disadvantages such as high production costs, high transportation and packaging costs, and insufficient optical prop...

AI Technical Summary

Problems solved by technology

Aviation plexiglass has disadvantages such as high production cost, high transportation and packaging costs, and insufficient optical performance.

Aviation inorganic glass is made of tempered ordinary silicate glass, which is compounded with multi-layer glass or compounded with transparent plastic; in order to achieve high enough strength, it is necessary to use thicker ordinary silicate glass; the existing Aviation plexiglass uses methyl methacrylate as the main raw material, adds a small amount of additives, and under the action of an initiator, the transparent plate is obtained through bulk polymerization. It has high impact resistance, but it needs to be bonded by multi-layer plates. affect optical properties
