Abstract

The invention discloses a protective and explosion-proof silicone polyurea resin coating composition and a construction method thereof. The protective and explosion-proof silicone polyurea resin coating composition comprises a main agent and a curing agent, wherein the main agent comprises the following components in percent by weight: 58-68% of polyoxypropylene diamine, 12-22% of diethyltoluenediamine, 3-10% of pigments and fillers, 0.5-2% of an ultraviolet screening agent, 0.7-2.3% of an adhesion promoter, 0.1-1% of a dispersant, 0.1-0.5% of a stabilizer, 0.5-3% of a defoamer and 3-15% of modified amino silicone oil; the curing agent is 100% by weight of an isocyanate prepolymer; and the protective and explosion-proof silicone polyurea resin coating composition provided by the inventionis constructed by the following steps: S1, substrate pretreatment; S2, substrate adjustment and coating; S3, primer coating; S4, protective and explosion-proof silicone polyurea resin coating composition coating; and S5, yellowing-resistant and highly hard paint coating. The protective and explosion-proof silicone polyurea resin coating composition provided by the invention can prevent influence of pressure loads caused by explosions and earthquakes on concrete structures or cement brick structures.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an explosion-proof silicone polyurea resin coating composition and a construction method thereof. Background technique [0002] With the rapid development of modern industry and the national economy and the improvement of architectural concepts, people have higher and higher requirements for the safety performance of industrial buildings and civil buildings. direction development. Among them, anti-explosion coatings are one of the urgently needed materials. The energy in the process of earthquakes and explosions will be transmitted through the surrounding air in the form of shock waves at an extremely fast speed, which will not only cause damage to buildings, but also cause personal injury. Therefore, it is urgent to obtain a method that can prevent the impact of the pressure load caused by explosions and earthquakes on concrete structures or cement brick structures, and has a...
