Abstract

The invention provides an explosion-proof glass based on a 3D network structure coating, which relates to the field of multifunctional glass. The explosion-proof glass is a sandwich structure with a glass substrate in the middle and an explosion-proof coating on the upper and lower surfaces; the explosion-proof coating is made of polyurea A 3D network structure coating formed by cross-linking imide elastomer and cerium-doped honeycomb zirconia, and the thickness of the explosion-proof coating is 0.5-1 μm. The present invention also provides a preparation method of the explosion-proof glass, specifically: firstly prepare a polyureaimide elastomer solution; then prepare a cerium / silica sol, compound the two and add auxiliary agents to obtain a film-forming liquid; The film-forming solution is coated on the two surfaces of the glass substrate respectively, and after vacuum drying, heat treatment is carried out under certain conditions to obtain explosion-proof glass. The anti-explosion coating of the anti-explosion glass has good bonding performance with the glass substrate, can be used for a long time in harsh environment without aging, and has a simple preparation method and low energy consumption.

Description

Technical field: [0001] The invention relates to the field of multifunctional glass preparation, in particular to an explosion-proof glass based on a 3D network structure coating and a preparation method thereof. Background technique: [0002] Glass has the advantages of good light transmission, sound insulation, light weight and easy installation. However, glass is also a typical brittle material with high strength and easy breakage. Under the action of strong blast load or severe impact load, glass tends to break easily and produce high-speed flying fragments, thereby harming the safety of personnel or structural facilities. Therefore, in order to ensure the safety of personnel and property, it is particularly important to improve the impact resistance and explosion resistance of glass, and has become a research hotspot at home and abroad. Then, laminated glass came into being. [0003] Laminated glass is a new type of composite structure, which has been widely used in de...
