Abstract
The invention relates to an uvioresistant aqueous styrene acrylic exterior wall coating. The coating is prepared by using styrene-acrylate emulsion as a film forming matter, using composite powder formed by nano titanium dioxide and magnesium-aluminum hydrotalcite as ultraviolet absorbers, adding pigments, fillers, addition agents, and the like. The preparation method is as follows: preparing the magnesium-aluminum hydrotalcite by adopting the single-drop method, mixing hydrotalcite seriflux neutralized through washing with the nano titanium dioxide, carrying out ultrasonic dispersion on the mixture for one hour, obtaining the composite powder formed by the nano titanium dioxide and the magnesium-aluminum hydrotalcite after sucking, filtering and drying, adding the composite powder to the prepared styrene acrylic exterior wall coating, and thoroughly dispersing to obtain the styrene acrylic exterior wall coating adopting the inorganic composite powder as the ultraviolet absorbers. The coating not only has the characteristics of good water resistance, alkali resistance, strong adhesive force, and the like of the styrene acrylic exterior wall coating, but also the ultraviolet resistance of the coating is greatly improved, the service life is prolonged and the coating is endowed with good fire resistance.
Description
Technical field
The present invention relates to a kind of exterior coating, particularly a kind of water-based styrene acrylic exterior wall coating with anti-ultraviolet property.
Background technology
Along with the enhancing of people's environmental consciousness, the application of water-based exterior wall paint more and more widely.Wherein, styrene acrylic exterior wall coating gains great popularity with performance such as its good water-fast, alkaline-resisting, scrubbing resistance and moderate relatively price.
But styrene acrylic exterior wall coating in the life-time service process, exist fade, come off, phenomenon such as dry linting, limited the development that phenylpropyl alcohol coating uses as exterior coating.And the main reason of these problems is exactly the ultraviolet destruction in the sunlight, and especially the medium wave band ultraviolet ray destructive force that is 280～320nm with short wave ultraviolet and the wavelength of wavelength 200～280nm is the strongest.The way that solves is exactly to add the additive with anti-ultraviolet property in coating, uvioresistant additive great majority in the past are organism, as salicylate system, benzophenone series, benzotriazole system etc., this class additive all has certain toxicity, and it has certain selectivity to ultraviolet sorption; Simultaneously, along with the prolongation of duration of service, its anti-uv-ray can weaken gradually, until inefficacy.Therefore, it is very necessary to develop a kind of efficient, nontoxic, environmental protection and long lasting uvioresistant additive.
Summary of the invention
The present invention proposes a kind of styrene acrylic exterior wall coating for preparing anti-ultraviolet property, with nano-TiO
2Compound with the Mg-Al hydrotalcite for preparing under the single droplet method condition, through ultra-sonic dispersion, made nano-TiO
2Composite granule with the Mg-Al hydrotalcite.This composite granule is applied to not only improve in the styrene acrylic exterior wall coating uviolresistance of coating, has prolonged the work-ing life of coating, give the coating good flame retardant property simultaneously.
The objective of the invention is to be achieved through the following technical solutions:
A kind of styrene acrylic exterior wall coating of anti-ultraviolet property, the mass percent of its described coating is composed as follows:
Filmogen, benzene emulsion 20%～28%;
Mg-Al hydrotalcite and nano-TiO
2Composite granule 0.5%～3%;
Color stuffing 32%～47%;
Water 20%～30%.
The styrene acrylic exterior wall coating of described a kind of anti-ultraviolet property, its described hydrotalcite are the stratiform Mg-Al hydrotalcite for preparing under the single droplet method condition.
The styrene acrylic exterior wall coating of described a kind of anti-ultraviolet property, its described Mg-Al hydrotalcite and nano-TiO
2Composite granule in both mass ratio 1:1.
The styrene acrylic exterior wall coating of described a kind of anti-ultraviolet property adopts single droplet method to prepare the Mg-Al hydrotalcite, will wash to neutral hydrotalcite slurries and nano-TiO
2Mix, and with its ultra-sonic dispersion 1 hour, and after obtain Mg-Al hydrotalcite and nano-TiO after the suction filtration drying
2Composite granule.
Embodiment
1, UV resistant performance test:
Adopt ultraviolet spectrophotometer to measure the UV-light absorbancy curve of uvioresistant additive; The method that adopts the irradiation at short distance of high energy ultraviolet lamp to film is tested the anti-ultraviolet property of styrene acrylic exterior wall coating.
2, flame retardant properties test:
Press GB/T 15442.2-1995 method test coating model flame retardant properties.
Embodiment one:
Accurately weigh Mg-Al hydrotalcite powder, the nano-TiO of equal in quality
2Powder and Mg-Al hydrotalcite and nano-TiO
2Composite granule, and load weighted testing sample is mixed with aqeous suspension (employing deionized water) respectively, add anion surfactant simultaneously, to keep the particulate suspension stability, behind ultra-sonic dispersion, put into sample pool respectively, test its ultra-violet absorption spectrum.Scanning wavelength scope: 200～400nm.
Embodiment two:
Select a kind of middle-grade styrene acrylic exterior wall coating prescription, and in prescription, add 0.5% different types of ultraviolet additive respectively: Mg-Al hydrotalcite, nano-TiO
2And Mg-Al hydrotalcite and nano-TiO
2Composite granule is made the modifying cinepazid exterior coating respectively, brushes making sheet, the anti-ultraviolet property of each model of test under high energy ultraviolet lamp irradiation at short distance condition.
Embodiment three:
Use the styrene acrylic exterior wall coating prescription identical, change Mg-Al hydrotalcite and nano-TiO with example two
2The addition of composite granule is made the modifying cinepazid exterior coating, brushes making sheet, the anti-ultraviolet property of each model of test under high energy ultraviolet lamp irradiation at short distance condition.
Main technical data is as follows:
1, anti-ultraviolet property
The UV-light absorbancy of the different types of ultraviolet additive of table 2
The UV resistant performance of table 3 styrene acrylic exterior wall coating
By table 2 and table 3 as can be seen, the anti-ultraviolet property that has added the exterior coating of UV light absorber all has raising in various degree, and the Mg-Al hydrotalcite only has very strong absorption in the UV-light short wavelength range, and nano-TiO
2Though at the entire ultraviolet wave band absorption is arranged all, it mainly is absorbed in the 270-350nm wavelength region, therefore, use separately wherein any, the raising of coating anti-ultraviolet property is all limited, and with both compound uses, has then improved greatly and filmed at broad wavelength region ultraviolet absorption ability.With Mg-Al hydrotalcite and nano-TiO
2The raising of composite granule addition, the anti-ultraviolet property of coating obviously strengthens.
2. the flame retardant properties of uvioresistant styrene acrylic exterior wall coating test
The combustion test result of styrene acrylic exterior wall coating model is as shown in table 4.As seen, only add nano-TiO
2Coating with not add the coating of uvioresistant additive basic identical required combustion time; Add the exterior coating of composite granule, along with the increase of composite granule addition, obviously prolong required combustion time; The coating that only adds the Mg-Al hydrotalcite is the longest required combustion time, illustrates that the Mg-Al hydrotalcite has good flame retardant property.
