Description
Technical field
The present invention relates to a kind of waterproof paint, particularly a kind of nano-material modified single-component polyurethane water-proof paint and preparation method thereof.
Background technology
Building water-proof paint, based on synthesized polymer material, pitch, polymer modified asphalt, inorganic materials etc., mixes appropriate auxiliary agent, material modified, packing material etc. and is processed into.Compared with waterproof roll, waterproof paint construction is simple and convenient, is applicable to the basal plane of any shape, and can form fine and close seamless film, and therefore, waterproof paint has been widely used in various waterproofing work, and achieves and develop rapidly.The waterproof paint of current American and Britain, day, method, De Deng industrially developed country all occupies suitable share in architectural waterproof material.While develop actively synthetic macromolecular waterproof coating and high polymer modified asphalt waterproof paint, the kinds such as positive active development water-based and inorganic water-proof coating, towards & environment-friendly type ' direction of waterproof paint sends out.
The development & application of China's building water-proof paint starts from the sixties in 20th century, tankage (as styrene tar etc.) at that time mainly with petroleum pitch, coal tar or chemical plant are main raw material, be processed into Emulsificated asphalt water-proof painting material, plastic ointment, reclaimed rubber modified waterproof asphalt material and styrene tar waterproof paint etc., these coating once obtained spread and used in waterproofing work.But due to these coating or because of poor quality, waterproof layer is short for working life, or because big for environment pollution, have a strong impact on workmen is healthy, be mostly put into obsolete product, consumption is just fewer and feweri.
The later stage seventies have developed polyether(poly)urethane waterproof paint; The mid-80 has succeeded in developing again tar polyurethane water-proof paint, and large-scale popularization is applied to waterproofing work; Within 1989, the Ministry of Construction rectifies national waterproof material market and investigates, and confirms that polyurethane water-proof paint is water-proof material trusty; After the nineties, polyurethane water-proof paint obtains and develops rapidly.Nineteen ninety, polyurethane water-proof paint was classified as one of the 8th Five-Year Plan for national economic and social development key popularized project by the Ministry of Construction, had formulated polyurethane water-proof paint building material industry standard (JC/T500-92), and had come into effect in 1993; Within 1998, non-tar polyurethane waterproofing paint is classified as one of 13 kinds of water-proof materials in National Residential recommended products by the Ministry of Construction, thus has greatly promoted polyurethane water-proof paint applying and developing in a healthy way in the whole nation.Large for tar polyurethane contaminative, it take petroleum pitch as the polyurethane water-proof paint of filler that the units such as Beijing Architectural Engineering Inst in 1998 develop a kind of, the units such as the ancient cooking vessel chemical building material company of Beijing gold have developed mono-composition poyurethane water-proof paint, and some units develop again solvent-free sprayed polyurethane waterproof paint subsequently.Other high molecular water-proof paint also is developed " as acrylic ester elastic waterproof paint, silicon rubber waterproof coating meanwhile! , water-based EPT rubber waterproofing paint etc.
But compare with developed country, China's polyurethane water-proof paint overall performance is poor, and quality is also unstable.Over nearly 10 years, polymer based nanocomposites obtains and develops rapidly, for the modification of polyurethane water-proof paint opens up a new way.Research shows: in dual-component polyurethane, add inorganic nano material, and while intensity improves, its elongation at break is correspondingly also improved.Single-component polyurethane water-proof paint is different from two component, and it is solidified by water in air, separately need not add solidifying agent, not containing solvent, has no irritating odor, easy construction, because of the improper detrimentally affect brought to the performance of waterproof coating of preparing burden when can avoid constructing.
Summary of the invention
An object of the present invention is the defect for above prior art, proposes a kind of good weathering resistance, acid resistance, the waterproof paint that the performance of film can be increased dramatically.
Two of object of the present invention is to provide the preparation method of above-mentioned waterproof paint.
In order to realize above goal of the invention, the present invention by the following technical solutions: a kind of nano modification single-component polyurethane water-proof paint, is characterized in that unit serving meter comprises following component by weight: polyether glycol 120 ~ 150 parts; TDI 60 ~ 70 parts; Phosphatase 11 0 ~ 20 part; Nano-meter CaCO3
310 ~ 20 parts; Nano-TiO
210 ~ 20 parts; Nano-ZnO 10 ~ 20 parts; Cetyl trimethylammonium bromide 1 ~ 5 part; Defoamer 2 ~ 4 parts; Dibutyl tin laurate 3 ~ 8 parts.
Described polyether glycol is the mixture of trihydroxy-polyoxytrimethylene ether, dihydroxyl polyoxytrimethylene ether.
Prepare the method for nano modification single-component polyurethane water-proof paint of the present invention according to above formula, comprise the following steps:
(1) by Nano-meter CaCO3
3, nano-TiO
2, nano-ZnO adds in cetyl trimethylammonium bromide, ultrasonic disperse 30min;
(2) polyether glycol, TDI, phosphoric acid add in reactor, stir and are warming up to 80 DEG C, add nanometer mixing solutions and defoamer, dibutyl tin laurate, and continue to be warming up to 120 DEG C, stirring reaction 2h, obtains product.
Nano material because of its have that particle diameter is little, specific surface area is large, particle micropore mainly with and the characteristic such as high adsorption capacity, there is obvious effect to the raising aspect such as the suspension stability of coating and the bonding force between coating and base material, the compactness of film, surface finish and abrasion resistance can be significantly improved; Reduce the surface energy of smearing surface.Nano-TiO
2there is the functions such as unique photocatalytic, excellent colour effect and ultraviolet screener, have broad application prospects in photocatalyst, makeup, ultraviolet-resistant absorbent, function ceramics, gas-sensitive sensor device etc.The particle diameter of nano-ZnO, between 1 ~ 100nm, is also called ultra tiny ZnO.Due to the granular of particle size, specific surface area sharply increases, and makes nano-ZnO create its surface effects, small-size effect and macro quanta tunnel effects etc. not available for body lumpy material.Nano-meter CaCO3
3particle diameter by 40 ~ 80nm not etc., is scattered in various oiliness and water-borne coatings, can the performance perameter such as very important resistance to sinking, stability in storage, thixotropy in effectively raising system.Add appropriate precipitated chalk in coating, paint to use as auxiliary rheological agents, anti-settling agent, dispersion aids, greatly can reduce the consumption of titanium dioxide, simultaneously not reduce gloss and hiding rare, there is the characteristics such as good gloss, exquisiteness, transparent, quick-drying; Effectively reach the object of anti-ultraviolet aging and anti-thermal ageing, improve mobility and the spraying property of goods.
Beneficial effect of the present invention is: add nano material in waterproof paint and carry out modification, effectively can improve weathering resistance, the acid resistance of waterproof paint, other mechanical properties of film also corresponding raising obtaining replying simultaneously.
