Description
Technical field
The present invention relates to technical field of road engineering, and in particular to a kind of new application of aqueous polyurethane, aqueous polyurethane
High tailored coating and preparation method thereof.
Background technique
Bituminous pavement is widely used in road construction and development, and people have more the coordination of road and environment
High requirement.However there is also many problems on road surface at present, and such as: road surface causes track, swelling and cracking etc. to endanger because of high temperature,
Road surface is because long term wear causes coefficient of sliding resistance to decline, and road surface is because of driver's optic nerve fatigue etc., these problems caused by color dullness
The safe application performance on road surface can be seriously affected.In addition to this, high temperature not only influences the safe application performance on road surface, Er Qiejia
Acute urban heat land effect.
Since bituminous pavement solar heat reflection paint does not change road surface original structure because having, only relies on and increase the reflection of road table
Rate reduces the advantage of pavement temperature and receives significant attention.It, can not only be to playing pitch in pavement usage heat reflection coloured coating
Play cooling effect in road surface, moreover it is possible to improve the pavement performance of bituminous pavement, such as extend the service life of bituminous pavement, be conducive to
The routine servicing of bituminous pavement promotes the raising of bituminous pavement quantity of operation and traffic transportation efficiency, urban heat island is effectively relieved
Effect etc..It in tunnel exit, turns round, the sections such as descending use heat reflection colour High tailored coating, not only can guarantee that road surface is excellent
Service performance, moreover it is possible to effectively driver safety be reminded to drive, alleviate the fatigue nerve of driver.Both at home and abroad to heat-reflective coating
There is a large amount of research, has applied the heat-reflecting material with road surface at present, can reach 5 DEG C of cooling value.People are to heat
Mainly in heat reflection surface side filler, U.S. ORNL and LBNL Liang Ge National Laboratory joint is numerous to build the research direction of reflectance coating
Material, pigments and fillers and coating manufacturer have carried out a 3 years by a definite date engineering, mainly to develop novel high reflection, colorful room
Topping material is purport.In this engineering, the database of nearly 100 kinds common pigments and fillers specific objects is established, including pigments and fillers
Title, color, mechanical performance, chemical characteristic, spectral properties etc., and also utilize the pigments and fillers refractive power number of spectrophotometer measurement
According to the theoretical model established about scattering coefficient S and absorption coefficient K, so as to deeper into the association attributes for understanding pigments and fillers.
Heat reflection coatings studies have shown that heat reflection filler is more, cooling effect is more obvious.However, heat reflection filler at
This is higher, and as the addition of heat reflection filler increases, resin can be deteriorated to the wrapped of filler；Filler also will affect resin
Filming performance further influences the service performance of coating；Coating cost can also be correspondinglyd increase by increasing heat reflection amount of filler simultaneously.
In addition, heat reflection coatings, which are applied to road surface, needs to add anti-skidding pellet, to increase pavement structure, meets driving and require, but be added
Anti-skidding pellet will affect reflectivity, and then influence cooling effect.Therefore, it only resides within by being added in the High tailored coating of road surface
Heat reflection filler is inadequate come the research for enhancing road surface cooling effect.
Currently, there are new research directions, for example, Publication No. during studying road surface High tailored coating
The Chinese patent application of CN109942776A discloses a kind of aqueous polyurethane emulsion and preparation method thereof, and also discloses use
The aqueous polyurethane emulsion prepares road surface High tailored coating.In the Chinese patent application, aqueous polyurethane emulsion is applied as cooling
The adhesive of material, compared to acrylic system coating, elastoplasticity is more preferable, free from extraneous odour；Compared to epoxy systems coating, toughness is more
Good, durability is more excellent；Compared to solvent borne polyurethane system coating, cost is relatively low and more environmentally friendly；In addition, aqueous polyurethane
Compared with the above system, safety and environmental protection is more in line with modern Man's Demands.But in the Chinese patent application, aqueous poly- ammonia
Ester lotion is only used as the adhesive of High tailored coating to use, and with the aqueous polyurethane prepare road surface High tailored coating when be added to one

Wherein, cooling heat reflection filler is the mixture of brilliant red stone-type nano-titanium dioxide and flatting silica.
2. the indoor simulation temperature reduction performance of High tailored coating is tested
Test method is that the coating of the coating of sample 6-10 and comparative example 1-3 is applied to concrete sample respectively, coating
Dosage is 1.8kg/m2, using iodine crow lamp solar simulating radiation, the temperature at concrete 2cm is recorded, and do blank control, tested
Low 7 DEG C, 8 DEG C, 7 DEG C, 8 DEG C, 8 are distinguished than blank test specimen temperature using the cooling coating specimens of sample 6-10 preparation as the result is shown
DEG C, it is respectively lower than 15 DEG C, 16 DEG C, 17 DEG C than blank test specimen temperature using cooling coating specimens prepared by comparative example 1-3.
3. completely spreading the indoor simulation temperature reduction performance test of the High tailored coating of anti-skidding pellet
Anti-skidding pellet is completely spread in the cooling coating with the coating preparation of the coating of sample 6-10 and comparative example 1-3 respectively,
And the temperature reduction performance of the coating of coating and comparative example 1-3 to the sample 6-10 for being paved with anti-skidding pellet is tested.Test side
Method is identical as above-mentioned test method.
Test result shows the cooling coating specimens for the sample 6-10 preparation for being paved with anti-skidding pellet than blank test specimen temperature point
7 DEG C not low, 8 DEG C, 7 DEG C, 8 DEG C, 8 DEG C are paved with the cooling coating specimens of the comparative example 1-3 preparation of anti-skidding pellet than blank test specimen temperature
Respectively lower than 7 DEG C, 8 DEG C, 7 DEG C of degree.
Above-mentioned indoor simulation temperature reduction performance test result is as shown in table 6.
6 indoor simulation temperature reduction performance test result of table
By the indoor simulation temperature reduction performance test result of table 6 it is found that not adding the High tailored coating (sample of heat reflection filler
6-10) cooling coating specimens obtained still have good cooling effect (cooling value can reach 7 DEG C).Although being added to heat
High tailored coating (comparative example 1-3) the cooling coating specimens obtained for reflecting filler have higher cooling effect, but ought completely spread
When anti-skidding pellet, cooling effect is affected significantly.And the High tailored coating provided by the invention without adding heat reflection filler
Temperature reduction performance do not influenced by anti-skidding pellet then.
Although an embodiment of the present invention has been shown and described, it will be understood by those skilled in the art that: not
A variety of change, modification, replacement and modification can be carried out to these embodiments in the case where being detached from the principle of the present invention and objective, this
The range of invention is defined by the claims and their equivalents.
