Abstract
The invention discloses self-cleaning heat-absorbing glass. A layer of ZnO nano array is arranged on the surface of the heat-absorbing glass; the thickness of the ZnO nano array is 50-500 nm, and the top diameter of the ZnO nano array is 1-100 nm; the ZnO nano array has the super-hydrophobic self-cleaning performance after being modified by a chemical substance with low surface energy, has higher light absorption performance, and can effectively prevent excessively powerful light ray from penetration. The self-cleaning heat-absorbing glass effectively improves the self-cleaning and heat-absorbing performances of traditional heat-absorbing glass.
Description
Technical field
The present invention relates to a kind of automatically cleaning antisolar glass, belong to Glass Surface Modification field.
Background technology
Antisolar glass is widely used in the door and window of buildings, exterior wall and car, ship windshield glass etc., plays the effects such as heat insulation, anti-dazzle and decoration, and antisolar glass can also absorb ultraviolet simultaneously, reduces the infringement of ultraviolet to human body and object.
Glass brings and also brings a new difficult problem easily simultaneously, and for common antisolar glass, the long-time rear surface that uses is easy to adhering dust, and is difficult to erasing, has a strong impact on the attractive in appearance of glass.The cleaning glass of high building needs the human and material resources of at substantial simultaneously, and has danger.In addition dust also can cause sharpness to decline on antisolar glass surface, affects the sight line of people, brings inconvenience to daily life.Along with the raising of people's living standard, the automatically cleaning of further raising antisolar glass, heat insulation, anti-dazzle performance also receive the concern of people day by day.
Summary of the invention
The object of the present invention is to provide one can realize self-cleaning antisolar glass.
For achieving the above object, the technical scheme that the present invention takes is as follows:
The present invention is in antisolar glass surface construction collimation ZnO nano array, and described ZnO nano array, first obtains ZnO crystal seed on antisolar glass surface, obtain ZnO nano array further combined with immersion method.Zinc acetate in seed crystal production process/ethanol solution concentration is 0.8 ~ 1.2 mmol/L; It is 3 ~ 7 times that sheet glass lifts number of times in the solution up and down; Annealing temperature is 330 ~ 350 DEG C.Bath temperature is 20 ~ 60 DEG C, and water bath time is 0.5 ~ 2 h.Described ZnO nano array, modifies by low surface energy chemical substance.Described ZnO nano array structural thickness is between 50 ~ 500 nm, and nano-array top end diameter is 1 ~ 100 nm.
Beneficial effect of the present invention: the ZnO nano array that described glass surface is constructed can realize the self-cleaning performance of glass surface, can improve absorptivity simultaneously, avoid strong light therethrough, and realized the heat absorption capacity of this glass.In addition ultraviolet effect is covered in addition.
Accompanying drawing explanation
Fig. 1 is automatically cleaning antisolar glass vertical view; Fig. 2 is automatically cleaning antisolar glass surface partial enlarged drawing.
In figure: 1. antisolar glass; 2. ZnO nano array.
Embodiment
Below in conjunction with accompanying drawing, enforcement of the present invention is described further:
Glass is present dark brown normal silicate antisolar glass 1 after adding coloring oxide in raw material.
At described antisolar glass 1 surface growth ZnO crystal seed, immersion method is adopted to obtain collimating ZnO nano array 2 further.
Concrete preparation technology is as follows for described automatically cleaning antisolar glass:
Antisolar glass is placed on respectively each ultrasonic 5 ~ 10min in acetone, ethanol, deionized water, dries up rear for subsequent use.
The preparation of ZnO crystal seed: the zinc acetate/ethanol solution of preparation 0.8 ~ 1.2 mmol/L, slowly lift after glass being immersed solution, pull rate is 1 ~ 2 mm/min, sheet glass lifts 3 ~ 7 times up and down in this solution, by sheet glass constant temperature 15 ~ 25 min in 330 ~ 350 DEG C after process, at room temperature cool after taking-up.
The preparation of ZnO nano array: preparation 2 ~ 4 mol/L sodium hydroxide and 0.25 ~ 0.5 mol/L zinc nitrate hexahydrate, keeps concentration ratio to be the mixing of 7:1 ~ 9:1 equal-volume.Glass containing ZnO crystal seed is put into wherein water bath with thermostatic control, and bath temperature is 20 ~ 60 DEG C, and water bath time is 0.5 ~ 2 h.
The sheet glass of growth ZnO nano array is placed in the vessel containing silicon fluoride, constant temperature 1.5 ~ 2.5 h in 115 ~ 125 DEG C of baking ovens, takes out after cooling.
The ZnO nano array of modifying through low surface energy can reduce drop in glass surface wettability, and drop exists with pearl form at glass surface, can speed away and take away surface dirt.
ZnO nano array causes the interval of conduction band and valence band to increase due to dimensional effect, significantly can strengthen absorbing properties, and ZnO nano array has the ultrared ability of very strong absorption simultaneously, and the ratio of specific absorption and thermal capacitance is large, plays heat insulation effect.In addition ZnO nano array can avoid strong light therethrough, makes dazzling sunlight become soft, plays anti-dazzle effect.Nano-ZnO covers ultraviolet performance in addition preferably, is used in glass surface and can reduces ultraviolet transmission, reduce the infringement to human body, can also prevent household utensils, books etc. from fading and denaturalization phenomenon because uviolizing causes.
