Abstract
The invention discloses a transparent antiultraviolet glass paint with high transparency and good adhesive force and hardness, which is made from platy shaped granular water nano-zinc oxide stuff or oil nano-zinc oxide stuff whose grain diameter is not greater than 8nm and average grain diameter is 5nm, urethane resin and coating additive. Visible light has high transparency to the glass paint. The invention can effectively prevent radiation of human bodies and aging and color fading of objects resulted from the strong ultraviolet rays, and has excellent adhesive force and surface hardness.
Description
Technical field
The present invention relates to the transparent antiultraviolet glass paint of a kind of highly transparent and good adhesion and hardness.
Background technology
Ultraviolet energy can cause skin aging even cause skin carcinoma easily, also can cause fading of various window curtains and floor, plastics and printed matter.The ultraviolet ray that is radiated at ground wavelength region and is 290-400nm accounts for 6% of total solar energy, wherein, belongs to 290-320nm short wavelength UV-B scope and accounts for 0.5%, and the wavelength region that belongs to 320-400nmUV-A accounts for 5.5%.Therefore, UV-A accounts for the overwhelming majority.Because the wavelength of UV-A is longer in ultraviolet ray, so easier cloud layer and glass of passing of UV-A, bigger to skin and object infringement, although UV-A is littler than the degree of depth of UV-B transdermal, but UV-B makes skin tanning easily in the skin surface scattering with by skin absorption, and UV-A is penetrable to hypodermis layer, produces free radical in skin histology, the free radical that generates makes skin aging produce wrinkle, and the elasticity of skin is reduced.In addition can cell membrane and gene cause some influence.Therefore people more and more pay close attention to the harm of antiultraviolet irradiation, and particularly windowpane such as windshield glass of automobile and room, office directly works the mischief to people's life.
The ultraviolet screener principle is divided into two classes substantially.One class is a mineral compound, as TiO
2, ZnO, ATO, ITO etc., but the transparency and ultraviolet absorption, reflection potential are all limit DeGrain very much.Another kind of is organic compound, most typical is benzotriazole cpd, they have the UV receptivity, but because the persistence of effect and the problem of secure context, the use field is very limited, therefore, does not have these problems at present, that is to say that good, the anti-ultraviolet ability of the transparency reaches the inorganic paint more than 99%, extensively is subjected to people's attention.
We ultraviolet screener or the coating that can see have following problem, TiO at present
2Has effective absorption region at UV-B, bad in UV-A wave band effect, particularly add to and prevent in the various resins that the ultraviolet effect is more undesirable, also reunite easily, zinc oxide has assimilation effect preferably at the UV-A wave band, but because our the so-called nano level ZnO powder that can see on the market, be more than the interior rice of 20-30 only, and it is more serious to reunite, and transparent and anti-ultraviolet effect is not very desirable, can not directly be used on the building glasses such as windshield and telecommuting chamber.
Chinese patent CN1235016A in November 17 in 1999 order disclose a kind of to the high-clarity of UV-A screening ability and the UV light absorber of good dispersion.This UV light absorber contains and is coated with the flake substrate that is no more than the super fine zinc oxide particle of 100nm with median size, and this absorption agent is optional to be handled through organosilicone compounds.
Chinese patent CN1563231A discloses a kind of glass that is applied to, transparent resin, the nano transparent heat-insulation composite coating of metal and cement surface on 01 12nd, 2005.This coating is made up of urethane resin, polyorganosiloxane resin, polyacrylic resin, nano-indium stannum oxide (ITO) powder, nano antimony tin oxide (ATO) powder, coatings additive(s) and thinner etc.
Though above-mentioned Chinese patent CN1235016A and CN1563231A have adopted inorganic UV light absorber, but particle is big, only indicated the following platy shaped particle solution of 100nm, and do not mention the antiultraviolet coating that can be applied in glass, and Chinese patent CN1563231A is a glass heat-insulating coating, the main raw material that adopts is that the metal oxide of ATO and ITO does not relate to zinc oxide, does not also mention anti-ultraviolet function.
Summary of the invention
At the above-mentioned deficiency of prior art, technical problem to be solved by this invention is to propose a kind of transparent antiultraviolet glass paint that is applied to building glass, vehicle glass surface.Visible light is to this coating transmissivity height, and this coating can effectively prevent intensive ultraviolet to human body, to problems such as the radiation of article, aging and shank colors, and good adhesive and surface hardness are arranged.
