NOVELTY - A preparation of ultra-low temperature resistant explosion-proof paint, involves (1) adding an appropriate amount of graphene/polyaniline composite material and polyisocyanate into the reaction kettle and stirring and heating to 105-110degrees Celsius, keeping the temperature for 60-70 minutes, vacuumizing for 45-60 minutes, and then inspecting the barrel to obtain component (A), (2) adding an appropriate amount of amino-terminated polyether, chain extender, pigment and silane coupling agent in sequence to the reaction kettle, stirring for 60-90 minutes, and then inspecting the barrel to obtain component (B) and (3) mixing component (A) and component (B) with an appropriate amount of organic solvent that does not contain active hydrogen components. USE - Preparation of ultra-low temperature resistant explosion-proof paint. ADVANTAGE - The ultra-low temperature resistant explosion-proof paint has a special stable three-dimensional porous structure, the impact resistance effect is very good, so the material cooperates with the urethane-based modified hexamethylene diisocyanate trimer, the construction performance effect of the anti-explosion paint at low temperature is obvious, it can satisfy the construction requirement of minus 50degrees Celsius, and has long anti-cracking effect.
