Description
Technical field
The present invention relates to LED bulb technical field of coatings, be specifically related to a kind of LED cell-shell protective membrane and preparation method thereof.
Background technology
Current LED technology is developing rapidly, due to LED there is power saving, the advantage such as the intensity of light source is high, illuminating area is wide, long service life, commercially occupied rapidly larger share and extensively obtained the favor of user.But also because the light source of the more general bulb of LED light source is strong, water in easy evaporative air and the organism on component is easily volatilized, organic vapor and water vapor are easily combined with glass cell-shell, atomization is turned white, the saturating not enough phenomenon of light to cause transparent glass cell-shell to present, have a strong impact on the lighting effect of LED, also make cell-shell easily scrap, work-ing life of LED shortens.
We once researched and developed a kind of water-borne coatings, China Patent Publication No. is CN103450758A, as light-transmissive film on the glass shell that this kind of water-borne coatings is particularly useful for being plated in LED bulb or fluorescent tube, this light-transmissive film has and has extraordinaryly resisted mist characteristic, thus slows down the light decay problem of light source.On the basis of this technology, we have made further improvement to water-based protective film, are especially suitable as the protective membrane of LED bulb cell-shell, have the advantages such as the protective membrane more environmental protection of developing than ever, safer, anti-fog power are stronger, transmittance is high.
Summary of the invention
The invention provides a kind of LED cell-shell protective membrane and preparation method thereof, the transparent bulb case solving current LED is easily atomized the problem of issue.
Technical scheme of the present invention is as follows:
A cell-shell protective membrane for LED, paint formulation is plated in inner wall and is formed by this protective membrane; Especially, described paint formulation is 100% calculating by total mass mark, and its formula comprises: ethanol 80% ~ 95%, acrylic resin 3% ~ 10%, leveling auxiliary agent 0.3% ~ 3.0%, water-based adherence auxiliary agent 1% ~ 3%, the resistance to soluble additive 1% ~ 3% of water-based.
The resistance to soluble additive of described water-based is preferably 2034 resistance to soluble additives.
Described water-based adherence auxiliary agent is preferably 1028 adherence auxiliary agents.
Described leveling auxiliary agent is preferably BYK-380N.
Cell-shell protective membrane of the present invention can make transparent glass cell-shell keep clear transparent bright principle as follows: the part of (1) LED lamp inside may exist the organic substance that can decompose; under the irradiation that LED light source is strong; the easy decomposition gasification of organic substance; especially the part of silica gel material commonly uses in LED lamp; silica gel material can volatilize silica gel steam under high light irradiates for a long time, and forming organic solvent after organic steam cooling can corrode glass lamp housing.The resistance to soluble additive of water-based and acrylic resin can in conjunction with the anti-solvent layers forming one deck densification, and fine and close anti-solvent layer effectively can deaden the contact of these solvents and glass, and prevents solvent mist to be set in glass surface, forms glass albefaction and produces mist spot.(2) water-based adherence auxiliary agent can make main paint vehicle no longer absorb moisture unnecessary in air, and water-based adherence auxiliary agent can form fine and close waterproof layer with reactive acrylic resin, prevent intense light source make the water evaporates in air become after water vapour with glass contact, can not make to haze in cell-shell wall.
Therefore, have employed acrylic resin as main paint vehicle, the resistance to soluble additive of water-based and water-based adherence auxiliary agent can react with main paint vehicle respectively, play water-fast and effect that is other nips.Even if use bulb for a long time, cell-shell also can be made to keep limpid transparent, keep the transmittance of bulb very high.And the material of this formula employing is all the material of safety, environmental protection, the bulb being coated with this protective membrane also has the advantage of use safety, environmental protection, environmentally safe, especially meets the environmental protection standard of external high criterion.
The present invention also provides a kind of preparation method of described cell-shell protective membrane, comprises the following steps:
(1) paint formulation is equipped with: put the ethanol of proportional in reaction vessel, then proportionally add acrylic resin, stir at least 15 minutes; Add leveling auxiliary agent, water-based adherence auxiliary agent and the resistance to soluble additive of water-based more in proportion successively, then stir at least 15 minutes; Filter;
(2) coating is plated to film: cell-shell, in the inner face of transparent glass cell-shell, is then placed in 80 DEG C of-120 DEG C of environment and toasts 10-15 minute by paint step (1) be equipped with, namely coating form protective membrane after drying.
LED cell-shell protective membrane provided by the invention, not only solves the problem that cell-shell turns white after long-term use, transmitance reduces.And prove that the LED shell being coated with this protective membrane is still thoroughly clear after 15 days by LED intense light source continuous light through test, and transmittance still can up to more than 95%.
