Abstract
The invention provides a preparation method of a polyurethane waterproof coating containing no tar. Di-n-butyl, polyether 330 and polyether 220 are put into a reactor according to prescription ratio, heated under 110 DEG C and dehydrated for 2.5 hours; after the temperature is cooled to 80 DEG C, toluene bitrichloroisocyanuric anhydride is added and reacted for 3 hours, the mixture is stirred evenly to prepare component A; di-n-butyl, extract oil, chlorinated paraffin, polyether 330, dodecyl benzene and MOCAO are put into a reactor according to prescription ratio, heated under 15 DEG C and dehydrated for 2 hours; then sericite powder and iron oxide pigment is added to be reacted for 3 hours under reaction temperature 15 DEG C, after reaction and that the temperature is cooled to 68 DEG C, MB is added to be stirred for 23 minutes to prepare component B. Components A and B are mixed at a ratio of 1:2 and stirred evenly. The invention has the advantages of no environmental pollution, strong cohesive force and no separation between different layers of the coating.
Description
Technical field
The present invention relates to a kind of method for preparing non-tar polyurethane waterproofing paint.
Background technology
At present, be used for building water-proof paint and mainly contain pitch, polyvinyl chloride glue, tar polyurethane coating, pitch need add heat construction, too high coating liquefaction trickling, the low cracking easily of temperature of causing easily of temperature; Polyvinyl chloride glue is difficult to solidify, and can't satisfy higher service requirements; Tar polyurethane coating causes environment, atmospheric pollution easily, and tensile strength, unit elongation are undesirable.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of method for preparing non-tar polyurethane waterproofing paint is provided.
Technical scheme of the present invention is: a kind of method for preparing non-tar polyurethane waterproofing paint, it is characterized in that: the weight proportion of component A is: tolylene diisocyanate 75-90 part, polyethers 330 170-210 parts, polyethers 220200-230 part, softening agent 10-28 part, component B weight proportion is: MB3-10 part, iron oxide pigment 5-30 part, MOCA45-80 part, polyethers 330 37-68 parts, dodecylbenzene 40-60.5 part, salty nasal mucus oil 180-210 part, clorafin 160-190 part, dibutylester 25-46 part, sericite in powder 425-550 part, with softening agent, polyethers 330, polyethers 220 was at 100-150 ℃ of decompression dehydration 1-3 hour, when treating that temperature is cooled to 75-95 ℃, add tolylene diisocyanate and reacted 2-5 hour, stirring is made into component A; With softening agent, extract oil, clorafin, polyethers 330, dodecylbenzene, vulcanizing agent out at 100-150 ℃ of decompression dehydration 1-3 hour, add sericite in powder then, pigment reacted 2-5 hour, temperature of reaction is 100-150 ℃, after reaction is finished, treat to add when temperature is cooled to 60-80 ℃ protective agent, stirred 20-30 minute, and be mixed with component B.
The present invention has the following advantages: non-environmental-pollution, and waterproof coating and concrete binding power are extremely strong, and it is not stratified to be coated with interlayer, can form integral waterproofing and film on waterproof layer, and product low temperature flexibility, solids content are up to standard.
