Description
Technical field
The invention belongs to waterproof paint technical field, being specifically related to a kind of polymer can the fast emulsion breaking freezing film waterproof paint and preparation method thereof of machine spraying.
Background technology
Current water-proof material is mainly based on waterproof roll and waterproof paint.
SBS, APP coiled material that modified bituminous pitch coiled material is as popular in current water-proof material market, it wants flame spray gun to carry out onsite surface hot melt, needs naked light, and technical requirements is high, easily makes the coking of surface heat melten gel.Web width only has one meter, and during laying, overlap joint is many, because of base shape requirement, needs cutting, more increases the amount of overlap joint, easily cause seam waterproof hidden danger; It is not strong to there is bonding force in selfadhesive asphalt water-proof coiled material, holds caducous problem.
The stickup of polymer coiled material and basic unit adopts neoprene system tackiness agent, its poor water resistance, and is easy to cause waterproof failure because coming unstuck, and therefore the bonding of polymer coiled material becomes the key of waterproof quality.The deficiency of these material property Problems existing and technology, limit the raising of waterproofing quality and perfect, the scheme being badly in need of proposition one complete solves the problems referred to above.
And waterproof paint is waterproof excellent material, point asphalt waterproofing paint and high molecular water-proof paint.Asphalt waterproofing paint all uses in low grade building because its performance issue is general.Chinese invention patent application (application number: 201210301863.3 applyings date: 2012-08-2) discloses employing special process, by the modified emulsifying asphalt of ultra-fine, suspension, micro-emulsion type and high molecular polymer rubber latex formulated fluid rubber asphalt adhesive emulsion components, mix with condensing agent component again, the water-based spray material prepared in proportion.
