Description
Technical field
The present invention relates to a kind of glass article and manufacture method thereof with functions such as hydrophobicity, wetting abilities.
Background technology
If have hydrophobicity or hydrophilic article surface give concavo-convex, if if then its surface hydrophobicity then can be improved the hydrophobicity wetting ability and then can improve wetting ability.
Open in the flat 11-286784 communique the spy and to disclose a kind of method, promptly, to contain polycondensation product, metal oxide microparticle of metal alkoxide and contain fluoroalkyl or the treatment solution of the silane compound of alkyl, be coated on the surface of glass, by dry, heating, form porous matter metal oxide layer with micro concavo-convex structure that fluoroalkyl or alkyl expose.Open flat 11-286784 communique according to the spy, this method, cheap and simple and easy to do, can give glass surface with high hydrophobicity.But the durability not insufficient of the micro concavo-convex structure that obtains by this method is abundant.
Open in the 2001-17907 communique the spy, disclose a kind of method, that is, the solution coat that will contain aluminum compound, stablizer etc. forms tunicle on matrix, under the condition of not heat-treating, by being immersed in the hot water, form concavo-convex tissue at matrix surface.In this method,, can remove with the methyl aceto acetate and be the stablizer of representative or be the additive of representative with poly-glycol by hot-water cure.Therefore, according to this method, need not high temperature and just can form concavo-convex tissue.But concavo-convex the organizing that obtains by this method do not have sufficient weather resistance yet.
Open in the 2003-236977 communique the spy, a kind of didirtresistance parts are disclosed, described didirtresistance parts have the concavo-convex tunicle that is made of the metal oxide that is formed on substrate surface, film with the hydrophobicity that forms on this concavo-convex tunicle surface, its outermost surface average roughness Ra is 0.004～10 μ m.The concavo-convex tunicle that obtains by this method is different from by above-mentioned 2 kinds of concaveconvex structures that method obtains, and metal oxide need not to get involved macromolecular compound and is formed directly on the substrate surface.Therefore, this concavo-convex tunicle has good weather resistance.But in the surface of this didirtresistance parts, the contact angle of water is 125 ° at most.This is because what form on successive tunicle surface is concavo-convex, does not have to substantially improve hydrophobic size.
Summary of the invention
The objective of the invention is, a kind of glass article is provided, described glass article has the good sag and swell of weather resistance, and the function of hydrophobicity, wetting ability etc. is good.
The invention provides a kind of functional glass article, described functional glass article contains, glass article; The metal oxide particle group of center line average that form, that cover the described surface below 90% more than 50% below the above 400nm of 10nm on the described glass article surface; With functional tunicle, described functional tunicle is, with cover described metal oxide particle group and also in succession the form in described glass article surface form, be selected from least a kind of film in hydrophobic film, hydrophilic film or the didirtresistance film.
The present invention also provides the manufacture method of above-mentioned functions glass article.This method is the manufacture method that comprises the functional glass article of following operation, and described operation is to contain chemical vapor-phase growing method (the chemical vapor depositionmethod of the unstripped gas of metallic compound and oxygenant by use; Hereinafter referred to as " CVD method ") on described glass article, form metal oxide particle group's operation and form the operation of the described functional tunicle that described metal oxide particle group is covered.
In the functional glass article of the present invention, because the metal oxide particle group directly forms on the surface of glass article, the sag and swell that is formed by the metal oxide particle group has good weather resistance.Functional tunicle, owing to be in the time of the surface of glass article, the metal oxide particle group to be covered in succession, the height of the protuberance that forms by the metal oxide particle group of activatable to greatest extent.Metal oxide particle group's center line average is in the scope of keeping that is suitable for taking into account by the improvement of the concavo-convex functions such as hydrophobicity that cause and weather resistance.The lip-deep metal oxide particle group's of glass article area ratio/occupancy ratio improves in the scope of function being suitable for.Like this, according to the present invention, can provide to have the functional glass article good sag and swell of weather resistance, that have good hydrophobicity etc.
In the manufacture method of the present invention, owing to be to form the metal oxide particle group by the CVD method, the metal oxide particle group can anchor at the surface of glass article.Therefore, the sag and swell that is formed by the metal oxide group has higher weather resistance.
The metal oxide microparticle subgroup that constitutes functional glass article of the present invention is formed in its surperficial glass article, if suitably select the material of metal oxide microparticle subgroup, only just can give play to good wetting ability whereby.Promptly, the present invention also provides a kind of wetting ability glass article, described wetting ability glass article comprise glass article and, on described glass article surface, form preferred be the metal oxide particle group of stannic oxide population, described metal oxide particle group covers the described surface below 90% more than 50%, its center line average is below the above 400nm of 10nm, and the contact angle of the water of measuring after dropping on the water droplet of 2mg on the described surface is below 20 °.This wetting ability glass article based on the sort of special surface shape, can be expressed the contact angle of low-down water, and utilizes its hydrophilicity to give play to good antifog property.
