Abstract
Organic silicon polyurea resin coating compositions and its construction method are used the invention discloses a kind of protection is explosion-proof, the explosion-proof protection with organic silicon polyurea resin coating compositions includes host agent and curing agent；Wherein, host agent includes: polypropyleneoxide diamine 58~68% according to weight percent, diethyl toluene diamine 12~22%, pigments and fillers 3~10%, ultraviolet screener 0.5~2%, adhesion promoter 0.7~2.3%, dispersing agent 0.1~1%, stabilizer 0.1~0.5%, defoaming agent 0.5~3%, modified amino silicon oil 3~15%；Curing agent be weight percentage for 100% isocyanate prepolymer；Present invention protection is explosion-proof to be constructed with organic silicon polyurea resin coating compositions using following steps: S1, substrate pretreatment；S2, substrate adjustment coating；S3, priming paint coating；S4, the explosion-proof organic silicon polyurea resin coating compositions coating of protection；The high hard paint coating of S5, color inhibition.The present invention can prevent the influence generated by explosion and seismic pressure load to concrete structure or cement brick structure object.
Description
Technical field
The present invention relates to the explosion-proof organic silicon polyurea cold coating combinations of technical field of coatings more particularly to a kind of protection
Object and its construction method.
Background technique
With modern industry, the fast development of national economy and the promotion of facade lighting, people to industrial building,
The security performance requirement of civil building is also higher and higher, therefore external wall product is also inevitable to new and high technology, high security
Direction develop.Wherein, protect it is explosion-proof with coating be at present there is an urgent need to one of material.Energy during earthquake, explosion etc.
Amount can be transmitted in a manner of shock wave the air on periphery at a terrific speed, not only cause to damage to building, and
And also bring along personal injury.Therefore, needing to obtain one kind can prevent by explosion and seismic pressure load to concrete
The influence that works or cement brick structure object generate, and the energy absorption of the shock wave and blast load to outside or inside
Coating high and that building facility damage and personal injury minimum can be made.
Summary of the invention
To solve the above problems, the invention proposes a kind of protection it is explosion-proof with organic silicon polyurea resin coating compositions and
Its construction method can be effectively prevent by explosion and seismic pressure load to concrete structure or cement brick structure object
The influence of generation is to avoid causing building facility damage and personal injury by explosion and earthquake.
In order to solve the above-mentioned technical problem, present invention employs following technical proposals: a kind of protection is explosion-proof poly- with organosilicon
Carbamide resin coating composition, including host agent and curing agent, the host agent are 1.05~1.15 to mix with curing agent by volume；
Wherein, the host agent includes: polypropyleneoxide diamine 58~68%, diethyl toluene diamine according to weight percent
12~22%, pigments and fillers 3~10%, ultraviolet screener 0.5~2%, adhesion promoter 0.7~2.3%, dispersing agent 0.1~
1%, stabilizer 0.1~0.5%, defoaming agent 0.5~3%, modified amino silicon oil 3~15%；
The curing agent be weight percentage for 100% isocyanate prepolymer.
Further, the isocyanate prepolymer NCO% content is 10%~20%.
