A kind of polymer modified asphalt waterproof paint
Technical field
The present invention relates to a kind of polymer modified asphalt waterproof paint.
Technical background
Along with people's living standard constantly improves, environmental consciousness is also in continuous enhancing, the environmental protection fundamental principle that human development modern industry need to be observed jointly especially.In recent years, the development of China's waterproof paint has obtained very much progress, and constantly by solvent-borne type to emulsion-type, by low grade to snappiness, high weather-proof, environment-friendly type and polyfunctional waterproof paint future development.
The selected acrylic ester elastic emulsion of China's waterproof paint at present, contain a certain amount of organic volatile (VOC), free formaldehyde and ammonia, do not reach the requirement of A, category-B in " limits of harmful substances in building water-proof paint " JC1066-2008 standard.In production, construction and application process, can, discharged to atmosphere, cause environmental pollution.External waterproof paint is just towards the development of aqueous environment protection aspect, as polymer modified asphalt waterproof paint, aqueous polyurethane waterproof paint etc. by contrast.
The share of market of China's polymer modified asphalt waterproof paint is also very low, and the waterproof paint of technology comparative maturity is polymer emulsion waterproof paint, polymer cement waterproof paint etc.Along with demand and the development in the continuous introduction of external waterproof paint kind and Environmental Protection in China type waterproof paint market, polymer modified asphalt waterproof paint, aqueous emulsion polyurethane water-proof paint will further be paid attention to and be developed.

The present invention is using esters of acrylic acid elastic emulsion and emulsified bitumen as filmogen, emulsify well, material that all can exhaust emission environment in production, construction and application process, environmental protection, and film has good tensile strength, elongation at break, low temperature flexibility and the cohesive strength to base material, add the physicals of coarse whiting, sericite in powder and the further enhanced coating of calcined kaolin.
Embodiment
Polymer modified asphalt waterproof paint of the present invention, its component comprises esters of acrylic acid elastic emulsion, emulsified bitumen, coarse whiting, sericite in powder, calcined kaolin, defoamer, dispersion agent, wetting dispersing agent, pH value conditioning agent, sanitas, thickening material and water, concrete, the weight percent of each component is: esters of acrylic acid elastic emulsion 20-30%, emulsified bitumen 20-30%, coarse whiting 13-23%, sericite in powder 4-6%, calcined kaolin 4-6%, defoamer 0.4-0.6%, dispersion agent 0.4-0.6%, wetting dispersing agent 0.4-0.6%, pH value conditioning agent 0.1-0.3%, sanitas 0.1-0.2%, thickening material 0.1-0.3%, surplus is water.
Embodiment 1: the weight percent of the each component of described polymer modified asphalt waterproof paint is: esters of acrylic acid elastic emulsion 30%, emulsified bitumen 20%, coarse whiting 18%, sericite in powder 5%, calcined kaolin 5%, defoamer 0.6%, dispersion agent 0.5%, wetting dispersing agent 0.4%, pH value conditioning agent 0.2%, sanitas 0.1%, thickening material 0.2%, surplus is water.
Embodiment 2: the weight percent of the each component of described polymer modified asphalt waterproof paint is: esters of acrylic acid elastic emulsion 30%, emulsified bitumen 30%, coarse whiting 13%, sericite in powder 4%, calcined kaolin 6%, defoamer 0.6%, dispersion agent 0.5%, wetting dispersing agent 0.4%, pH value conditioning agent 0.2%, sanitas 0.1%, thickening material 0.2%, surplus is water.
Embodiment 3: the weight percent of the each component of described polymer modified asphalt waterproof paint is: esters of acrylic acid elastic emulsion 20%, emulsified bitumen 30%, coarse whiting 23%, sericite in powder 6%, calcined kaolin 4%, defoamer 0.6%, dispersion agent 0.5%, wetting dispersing agent 0.4%, pH value conditioning agent 0.2%, sanitas 0.1%, thickening material 0.2%, surplus is water.
Described defoamer is polyoxyethylene nonylphenol ether, described dispersion agent is Sodium hexametaphosphate 99, described wetting dispersing agent is sodium polyacrylate, described pH value conditioning agent is the organic amine of hydroxyl and amido composition, described sanitas is isothiazolinone, and described thickening material is formed by acrylate, methacrylic ester copolymerization.
Described emulsified bitumen softening temperature can not be too low or too high, and too low thermotolerance is bad, is too highly difficult for emulsification, and therefore emulsified bitumen mixing temperature is 40-80 DEG C.
