Abstract

The invention relates to the technical field of coating production and construction modes, in particular to an anti-explosion high-impact anti-layer-drop combined polyurea coating and a construction method thereof. The anti-explosion high-impact anti-layer-drop combined polyurea coating comprises a main agent and a curing agent, the main agent comprises, by weight, 60-65% of polyetheramine, 20-25% of diethyltoluenediamine, 8-10% of a pigment, 1-2% of an anti-ultraviolet agent, 1-2% of an anti-yellowing agent, 1-2% of an adhesion force enhancer, 0.1-1% of a dispersant, 0.1-0.5% of a stabilizer, 1-2% of a defoaming agent and 10-15% of modified amino silicone oil, wherein the curing agent is a modified isocyanate prepolymer. By means of the design, damage to a protected base material, a building body, a cement brick wall or a reinforced concrete structure due to huge load pressure caused by improper explosion and unexpected earthquakes can be effectively prevented, and unnecessary damage hidden danger caused bybuilding floor dropcan be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of paint production and construction methods, in particular to a combination polyurea paint with high explosion-proof performance, impact resistance and delamination resistance and a construction method thereof. Background technique [0002] The development of human beings living on the earth has gradually shifted from the Stone Age to the era of industrial modernization. The changes in personal living conditions are increasing and developing rapidly. Therefore, the living conditions and safety factors are also improving, and the progress of the building itself is also improving with each passing day. , There are more and more cases of adopting high-tech, and the old construction methods that have been replaced have also been realized one by one, but for the climate change of natural phenomena, the occurrence of earthquakes, the layer drop of the building itself, and the explosion situation affected by extern...
