The composite light-resistant color enhancer composition for the exterior wall coating comprises the following components in part by weight: 50 parts of water, 1 to 3 parts of nonylphenol polyoxyethylene ether, 10 to 15 parts of nano titanium white, 8 to 12 parts of polyvinyl pyrrolidone, 0.1 to 0.3 part of butyl sodium naphthalene sulfonate, 30 to 50 parts of ethanol, 0.3 to 0.6 part of silane coupling agent, 4 to 8 parts of ditriazine amino stilbene, 1 to 3 parts of 4,4'-bi(diphenylamino-trans styryl) biphenyl, 1 to 3 parts of p-tert-butylphenyl salicylate and 1 to 3 parts of 1-oxo-2,2,6,6-tetramethylpiperidine. The composition can prevent a surface layer of the coating from being oxidized, broken, degraded and the like; therefore, the coating surface is whiter, brighter and more colorful.
Description
Technical field
The present invention relates to a kind of exterior coating with compound fast light and toner composition.
Background technology
China is one of maximum coating country of consumption, high speed development along with China's economic, especially along with the improvement of living standards of the people, per-capita housing is increasing, also promoted the flourish of market of real estate, every decorations such as building, villa to the requirement of coating quality in continuous raising.Because the protective layer of every decorations such as building, villa; often be exposed in sunlight and the air; because of being subjected to the effect of ultraviolet ray, heat, oxygen, water, microorganism and all contaminations; series of chemical such as oxidation, chain rupture, degraded, acidolysis may take place in the surface of protective layer; make phenomenons such as the coatingsurface glossiness descends, fades, jaundice, the biggest factor that causes these phenomenons is the photooxidation resistance that the ultraviolet ray in the sunlight causes.Therefore need take more technical measures to solve the photooxidation resistance problem of coating surface layer.
Summary of the invention
The object of the present invention is to provide a kind of exterior coating with compound fast light and toner composition, remedy above-mentioned defective to overcome.
Exterior coating of the present invention comprises the component of following weight part with compound fast light and toner composition:
50 parts in water
1～3 part of polyoxyethylene nonylphenol ether
10～15 parts of nanometer titanium dioxides
8～12 parts of polyvinylpyrrolidones
0.1～0.3 part of sodium butylnaphthalenesulfonate
30～50 parts of ethanol
0.3～0.6 part of silane coupling agent
4～8 parts of two triazine amino-stilbenes
4,4 '-1～3 part in two (diphenylamino-trans-styryl) biphenyl
Salicylic acid is to 1～3 part of tertiary butyl phenyl ester
1～3 part in 1-oxygen base-2.2.6.6-tetramethyl piperidine
The particle diameter of nanometer titanium dioxide is 50～80 nanometers, and preferably rutile-type is selected abundant Xinghua, Shandong chemical product for use.
Silane coupling agent preferred vinyl triethoxyl silane;
The polyvinylpyrrolidone weight-average molecular weight is 3000～6000;
Two triazine amino-stilbenes can adopt the product of Kingsoft, Shanghai longitude and latitude chemical industry company limited trade mark for " 31# white dyes ";
4.4-two (diphenylamino-trans styryl) can adopt Jiangxi Province's Xinhua's chemical plant trade mark of recommending properly qualified persons for service to be the product of " XPS2 white dyes ";
It is the product of CAS:768-66-1 that 1-oxygen base-2.2.6.6-tetramethyl piperidine adopts the Quzhou newly to rise chemical industry company limited model.
The preparation method comprises the steps:
(1) under the normal temperature, nanometer titanium dioxide and polyoxyethylene nonylphenol ether are added to the water, dispersed with stirring 20～40 minutes adds polyvinylpyrrolidone, is warming up to 40～50 ℃, adds sodium butylnaphthalenesulfonate again;
(2) with two triazine amino-stilbenes, 4,4 '-two (diphenylamino-trans styryl) biphenyl and silane coupling agent, be dissolved in the ethanol, add salicylic acid again to tertiary butyl phenyl ester and 1-oxygen base-2.2.6.6-tetramethyl piperidine;
(3) (2) are joined in (1), be warming up to 60～70 ℃, be incubated 1～3 hour, can obtain product.
Exterior coating of the present invention can make an addition in the general exterior coating with compound fast light and toner composition, and adding weight is 1～3%.
Exterior coating of the present invention is with compound fast light and toner composition, utilize UV light absorber ultraviolet powerful absorption and hindered amine as light stabilizer to be caught the synergistic effect of free radical and multiple functions such as hydroperoxide decomposition and quencher singlet oxygen, choke suppress the coating surface layer may take place oxidation, chain rupture, degraded, etc. series of chemical, the Degradation of the aging and polymkeric substance of the coatingsurface that slowed down, titanium dioxide has improved the corrosion-resistant and wear resistance of opacifying power, reducing power of filming, strengthen the mechanical strength of filming, prolonged the life-span of coating.Whitening agent can absorb sightless UV-light simultaneously, be converted to long blue light of wavelength or the visible light of purple, thereby can compensate undesired little yellow in the matrix, reflect simultaneously than the more visible light of original incident wavelength scope, thereby make coatingsurface seem whiter, brighter, more bright-coloured.
