Abstract

The invention discloses a preparation method of an explosion-proof heat-preservation multifunctional sheet material of a foaming concrete sandwich. The sheet material comprises an outer wall heat-preservation sheet material core body; and explosion-proof light mortar outer protection plates are respectively spliced on the surfaces of the two sides of the outer wall heat-preservation sheet material core body. The explosion-proof heat-preservation multifunctional sheet material of the foaming concrete sandwich has stronger explosion-proof capability and can be used for protecting the safety and stability of a main body structure of a building under the effect of protecting an explosive load; and the heat-preservation, heat-insulation, fireproof, environmentally-friendly performances and the like of the explosion-proof heat-preservation multifunctional sheet material are better than those of like products. The method comprises the following steps of: A, preparing an explosion-proof and light-weight mortar outer protection plate; and B, preparing a foaming concrete core body. The heat-preservation, heat-insulation, fireproof, environmentally-friendly performances and the like of the explosion-proof heat-preservation multifunctional sheet material are better than those of like products and the construction process is simple. Panels on the two sides of the explosion-proof heat-preservation multifunctional sheet material of the foaming concrete sandwich are made of high-strength and light-weight mortar and the strength of the panels is higher. When the panels are cast and molded, a metal grid reinforcing layer is additionally arranged so that the panels have stronger anti-explosion capability.

Description

technical field [0001] The invention relates to an explosion-proof and heat-preserving multifunctional plate with a foamed concrete sandwich, which belongs to the field of new wall heat-preserving materials. Suitable for external wall insulation requirements of industrial or civil buildings. Background technique [0002] With the continuous improvement of people's quality of life, the performance requirements for building exterior wall insulation panels are also getting higher and higher. Although the performances of the existing thermal insulation boards such as light weight, thermal insulation, and fire prevention basically meet the requirements, their explosion-proof performance is not satisfactory. Existing ordinary external wall insulation boards will suffer devastating damage under the explosion and explosive impact of external loads, and may damage the main structure of the building. The splashes formed on the surface of the building under the impact load will also ...
