Abstract
The invention discloses a waterborne polyurethane waterproofing paint, which is composed of the following raw materials in parts by weight: 40-50 parts of waterborne polyurethane resin, 5-8 parts of 2-ethoxyethyl acetate, 20-30 parts of teflon, 10-15 parts of actinolite powder, 2-3 parts of sodium metasilicate, 1-2 parts of sodium dodecyl sulfate, 2-3 parts of poly-(tetramethylene ether) glycol, 1-2 parts of dodecyl trimethyl ammonium chloride, 5-10 parts of deionized water, and 7-10 parts of a bonding aid. The waterproofing paint disclosed by the invention is non-toxic and tasteless, and does not pollute the environment, therefore, the waterproofing paint is green and environmental-friendly; the waterproofing paint is good in weathering resistance, does not flow at high temperature and does not crack at low temperature; and the waterproofing paint is good in aging resistance, high in elongation at break, and good in waterproofing effect.
Description
Technical field
The present invention relates generally to a kind of coating, relates in particular to a kind of aqueous polyurethane waterproof paint.
Background technology
Existing waterproof paint has multiple, some constructing operation complexity and poor performance; Some waterproof effects are poor, and weather resistance is poor; What have needs not only construct trouble but also exist batching to be forbidden to cause degradation to affect waterproof effect of field mix; The easy generation bubble having, surface gloss is bad, and it is necessary therefore producing a kind of high performance waterproof paint.
Summary of the invention
The object of the invention is just to provide a kind of aqueous polyurethane waterproof paint.
The present invention is achieved by the following technical solutions:
A waterproof paint, it is comprised of the raw material of following weight parts:
Waterborne polyurethane resin 40-50, ethylene glycol ether acetate 5-8, tetrafluoroethylene 20-30, Tremoliteor Tremoliteasbestos powder 10-15, Starso 2-3, sodium laurylsulfonate 1-2, PTMG 2-3, Dodecyl trimethyl ammonium chloride 1-2, deionized water 5-10, adhesive aid 7-10;
Described adhesive aid is comprised of the raw material of following weight parts:
Polyvinyl acetate emulsion 30-40, polyvinyl alcohol 6-10, Radix Notoginseng powder 2-3, carbomer 4-6, N-ethyl-neighbour, para toluene sulfonamide 0.5-1, sodium silicoaluminate 2-3, water are appropriate;
Above-mentioned sodium silicoaluminate is mixed with polyvinyl alcohol, be preheating to 30-40 ℃, ball milling 10-15 minute, joins in this compound weight 3-5 water doubly, be heated to 75-85 ℃, fully stir, add Radix Notoginseng powder, carbomer, rising temperature is 100-120 ℃, being stirred to temperature is 25-30 ℃, add each raw material of residue, fully ball milling, obtains described adhesive aid.
A preparation method for aqueous polyurethane waterproof paint, comprises the following steps:
Above-mentioned PTMG is mixed with deionized water, be heated to 30-35 ℃, add Starso, Tremoliteor Tremoliteasbestos powder, tetrafluoroethylene, 400-600 rev/min of dispersed with stirring 5-10 minute, add each raw material except waterborne polyurethane resin, stirring at normal temperature 1-2 hour, then add waterborne polyurethane resin, fully be uniformly mixed, obtain described aqueous polyurethane waterproof paint.
Advantage of the present invention is:
The waterproof paint that the present invention produces is nonpoisonous and tasteless, nonpollution environment, and environmental protection, weather resisteant is good, and high temperature does not trickle, and low temperature does not chap, and has good ageing resistance, and elongation at break is high, good water-proof effect.
