A square-shaped high-strength explosion-proof plate and its preparation method

Abstract

The invention discloses a square-shaped high-strength explosion-proof plate and a preparation method thereof, comprising two aluminum plates arranged in parallel, a support plate arranged in parallel between the two aluminum plates, and arranged between the support plate and the aluminum plate The vermiculite plate is vertically penetrated by one side of the vermiculite plate, the support plate is connected to a plurality of through holes of the other aluminum plate, and the compression steel bar is inserted into the through hole and connected with the two aluminum plates. The vermiculite board is made of 50-60% of expanded vermiculite, 15-25% of fly ash floating beads, 5-15% of polymerized inorganic gel, and 10-15% of gypsum powder. The square-shaped high-strength explosion-proof plate is prepared through molds and specific preparation method steps. The "Tian"-shaped compression structure formed by its aluminum plate, support plate and compression steel bar greatly increases the explosion-proof and compression-resistant performance of the explosion-proof panel. The explosion-proof and compression-resistant performance is excellent, the manufacturing process is simple, and it is convenient for actual production.

Description

technical field [0001] The invention relates to an explosion-proof plate, in particular to a square-shaped high-strength explosion-proof plate and a preparation method thereof. Background technique [0002] With the development of the economy, the buildings where people live and work are getting taller and denser, and the potential threat brought by explosions is also increasing. At the same time, military fortifications such as warehouses, shooting ranges, dormitories, ammunition depots, command posts, garages, hangars, oil depots, equipment rooms, temporary warehouses, bomb disposal stations, field hospitals, checkpoints, and various flammable and explosive petrochemical And other products, often cause huge casualties and economic losses due to explosion. How to reduce the degree of explosion damage as much as possible is a problem to be solved by personnel in related fields. One of the current methods to deal with this problem is to install explosion-proof panels on the...
