Abstract
The invention discloses a textured mirror surface with the self-cleaning effect. The bionic structural design is adopted. The textured mirror surface structurally comprises a mirror surface body and textured units which are constructed and evenly distributed on the mirror body. The textured units are not planar. When the textured mirror surface is applied to an automobile rearview mirror, rainwater can be effectively prevented from adhering to the automobile rearview mirror, dust can be cleaned away by the automobile rearview mirror, and time required for fogging and frosting is prolonged.
Description
Technical field
The present invention relates to a kind of texturing minute surface, relate in particular to a kind of texturing minute surface with self_cleaning effect that can be applicable to automobile rearview mirror.
Background technology
Automobile rearview mirror is the pith of automobile active safety configuration, is moveing backward, is stopping production, overtakes other vehicles and most important to aspects such as vehicle condition understanding below, assurances, and therefore the vision of back mirror is clear is absolutely necessary in vehicle operating.
The subject matter that existing automobile rearview mirror faces is on rainy day, and rainwater sticks on back mirror or rainwater is beaten on back mirror, makes mirror field of view blur, and chaufeur cannot be understood the situation of vehicle back and both sides, causes occurring traffic accident.In addition in autumn and winter season, particularly in the weather colding and heat succeed each other and greasy weather, the back mirror of automobile is very easily gone up frost, and upper fog, has a strong impact on the field of view of automobile driver to rear, and this is also the hidden danger of common traffic accident.
Conventionally the interim solution that runs into above-mentioned situation is that chaufeur stops or do not stop and turns down Qianmen glass by back mirror wiped clean, but this mode is more dangerous in automobile is advanced.Even by minute surface wiped clean, can again adhere to water again or haze in extremely short time inside rear-view mirror and beat frost.Conventional technological means is used for the rain-removing method of automobile rearview mirror and mainly contains: (1) is coated with protective liquid and on minute surface, forms one and have clear water effect top layer on back mirror, make rainwater can not on minute surface, form water droplet, but shortcoming is that service life is short; (2) pasting protective film on back mirror, its principle of work and protective liquid are basic identical, but because the hardness of protective film is low, often wiping; (3) on back mirror, install mechanical device additional: wiper and hair-dryer etc., exist that complex structure, size are large, effect is bad.Be mainly after eyeglass, to install heating wire additional for the demist Defrost method of automobile rearview mirror, but can only demist defrost, water removal effect is very poor.
At present, also do not find a kind of comprehensively technology can solve back mirror water proof anti-soil, anti-fog and antifrost problem simultaneously.
Summary of the invention
Applicant is for many years devoted to research and how solves the many defects that exist in prior art, and from bionic design, find that the rainwater on plant leaf surface can be because capillary effect forms the globule, as long as blade face tilts a little, the globule will roll from blade face, even through a down-pour, leaf surfaces always can keep dry, and the globule simultaneously rolling can be taken away dust mud in passing together, reaches the effect that oneself is clean.
Based on above-mentioned discovery on bionics, applicant has completed texturing minute surface of the present invention.
Specifically, the present invention is achieved through the following technical solutions:
Have the texturing minute surface of self_cleaning effect, the texture unit of evenly constructing by minute surface with on minute surface forms, and described texture unit is non-planar configurations.
Be configured to the super hydrophobic surface of specular surface by above-mentioned non-planar junction, produce better waterproof property, drop from the teeth outwards angle of contact is more large, there is good result suppressing to haze aspect frosting, reach minute surface anti-get wet and pollute, anti-hazing and the object of frosting.
Concrete, available non-planar configurations is not restricted, anyly all can be used for the present invention at the feasible nonplanar structure of geometric extent, consider the cost needs of structure design and actual production, preferably, described texture unit is square column type convex closure, cylindrical convex closure, square column type pit, cylindrical pit, vee-cut or linear grating groove.
Wherein, when described texture unit is square column type convex closure, square column type convex closure length of side a=50nm～1 μ m, square column height h=20nm～500nm, adjacent square column distance s=100nm～5 μ m.
Wherein, when described texture unit is cylindrical convex closure, the circular cylindrical projection column diameter d=50nm～1 μ m that takes all of, cylinder height h=20nm～500nm, adjacent column distance s=100nm～5 μ m.
Wherein, when described texture unit is square column type pit, square column type pit length of side d=50nm～1 μ m, square column degree of depth h=20nm～500nm, adjacent square column distance s=100nm～5 μ m.
Wherein, when described texture unit is cylindrical pit, cylindrical pit diameter d=50nm～1 μ m, cylinder degree of depth h=20nm～500nm, adjacent column distance s=100nm～5 μ m.
Wherein, when described texture unit is vee-cut, between the adjacent two groove floors of vee-cut, the scope of angle is θ=20～160 °, and vee-cut ridge is wide is a=50nm～1 μ m, and groove depth is h=20nm～500nm, adjacent vee-cut groove width s=100nm～5 μ m.
Wherein, when described texture unit is linear grating groove, grating ridge is wide is a=50nm～1 μ m, and groove depth h is 20nm～500nm, and adjacent gratings groove groove width is s=100nm～5 μ m.
Above-mentioned texture unit, can build by any available method of mechanical field, include but not limited to as follows: texturing cell cube structural form and the size of designing different minute surfaces, obtain best texture cell cube form and size according to bionics Study, in specular material, construct and there is the nanometer texture such as convex closure, pit or the groove of certain geometrical shape by technology such as inductively coupled plasma etching, nano impression, photoetching.
Texturing minute surface of the present invention, has the effect of significant waterproof, dust protection and anti-fog and antifrost.Applicant carries out Experimental Comparison analysis to smooth mirror surface and texture minute surface of the present invention in research process, find successfully to change minute surface wetting ability into super-hydrophobicity, micro-analysis finds that can stablize absorption by the introducing of bionical texture structure forms one deck air film, effectively hinder the infiltration of surperficial upper water droplet, thereby made its surface there is ultra-hydrophobicity to realize antiseized water, automatically cleaning, anti-hazing and effect of frosting.
Owing to having effect as above, texturing minute surface of the present invention, can design for the mirror surface structure of the similar structures product under various vehicles or other purposes, especially can be for the back mirror of the vehicle such as automobile, motor bike.
