Abstract
The invention discloses a kind of aqueous polyurethane waterproof paint, it is made up 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, the waterproof paint weather resisteant that the present invention produces is good, high temperature does not trickle, low temperature does not chap, there is good ageing resistance, elongation at break is high, good water-proof effect.
Description
Technical field
The present invention relates generally to a kind of coating, particularly relates to a kind of aqueous polyurethane waterproof paint.
Background technology
Existing waterproof paint has multiple, the complicated and poor performance of some constructing operation; Some waterproof effects are poor, and weather resistance is poor; The field mix that needs had not only is constructed trouble but also there is batching and forbidden to cause degradation to affect waterproof effect; The easy generation bubble had, surface gloss is bad, and it is necessary for 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 kind of aqueous polyurethane waterproof paint, it is made up 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 made up 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 DEG C, ball milling 10-15 minute, join in this compound weight 3-5 water doubly, be heated to 75-85 DEG C, abundant stirring, adds Radix Notoginseng powder, carbomer, and raised temperature is 100-120 DEG C, being stirred to temperature is 25-30 DEG C, add each raw material of residue, abundant 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 DEG C, 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, and nonpollution environment, environmental protection, weather resisteant is good, and high temperature does not trickle, and low temperature does not chap, and have good ageing resistance, elongation at break is high, good water-proof effect.
