A kind of preparation method of rubber asphalt-polymer cement waterproof paint

The invention discloses a kind of preparation methods of rubber asphalt-polymer cement waterproof paint, and matrix pitch is heated, and open cutter, and modifying agent is added, and shearing is added stabilizer, continues to shear, and modified pitch is made in stirring development；Powder is added gradually in liquid material, dispersion stirring while adding, places and carry out brokenly bubble, be stirred for, stood, polymer cement waterproof paint is made；Gained modified pitch is heated, preheating emulsified asphalt colloid mill is first added soap lye, then modified pitch is slowly at the uniform velocity added, addition defoaming agent tributyl phosphate, cooling after stirring and emulsifying, obtained rubber asphalt-polymer cement waterproof paint.It is mixed with polymer styrene-acrylic emulsion list, using cement-three component of coarse whiting-silica flour, adds water-reducing agent, cellulose ether, the water-repellent paint of preparation can form the fine and close network coating structure of cohesion, to reach the requirement of coating high strength and high flexibility；The filling effect of cement and polymer is good, and coating property is excellent.
