Description
Technical field
The present invention relates to a kind of component of lighting device, especially a kind of lampshade.
Background technique
LED illumination light source due to it is energy saving, small in size, durable the advantages that be widely applied as light source, but the white of LED
Light source can generate a large amount of blue light, and blue light has damaging effect to human eye, and therefore, eliminating LED blue light harm is always to illuminate
The research hotspot in field.Currently, many anti-blue light lighting devices available on the market are to make anti-blue light lamp based on coating technique
Cover, by the blue light in reflection source, thus achieve the effect that anti-blue light, but since the technology is by the blue light portion in light source
Point fully reflective, the total brightness of light source will appear a degree of decaying, and light source range of exposures is in yellow, influence user's
Depending on object clarity and to the judgement of color.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides that a kind of anti-blue light effect is good, does not influence the anti-of color judgement
Blue light lampshade and preparation method thereof.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of lampshade with anti-blue light coating, the surface of the lampshade are attached with anti-blue light coating, the anti-blue light coating
With a thickness of 100-150 microns, the constituent of the anti-blue light coating indicates by weight percentage: the cumarin of 0.1-0.5%
540, the Nano silver grain of 0.1-0.5%, the acrylic emulsion of 10-20%, the styrene-acrylic emulsion of 10-20%, 40-50% it is transparent
The profit of powder, 1-5% dipropylene glycol methyl ether, 2-6% dipropylene, the dimethylethanolamine of 0.1-0.5%, 0.2-0.8%
The deionized water of hygroscopic water powder, the defoaming agent of 0.1-0.5%, the thickener of 0.1-0.5%, 10-15%.
The fineness of the transparent powder is 800 mesh or more.
A method of the lampshade with anti-blue light coating being prepared, steps are as follows: first by the deionized water, profit
250r/min middling speed in Scattered Kettle, which is added, in hygroscopic water powder and defoaming agent disperses 5 minutes, then the transparent powder and talcum powder are added
400r/min high speed dispersion 30-45 minutes in the Scattered Kettle, next by the cumarin 540, Nano silver grain, acrylic acid
Lotion and styrene-acrylic emulsion are added in the Scattered Kettle 400r/min high speed dispersion 10-15 minutes, finally by the Scattered Kettle revolving speed
Be adjusted to middle and slow speed of revolution 150r/min, be slowly added into the dipropylene glycol methyl ether, dipropylene, dimethylethanolamine and
Thickener, after raw material adds, the Scattered Kettle keeps middle and slow speed of revolution 150r/min to stir 10 minutes, can be prepared by anti-blue light
Coating is adhered to by the anti-blue light coating according to the different shaping of lampshade by the films mode such as spraying, roller coating, dip-coating, erasing
In the cover surface, the lampshade with anti-blue light coating can be prepared by.
The beneficial effects of the present invention are: the anti-blue light lampshade that comparison is made based on coating technique, main blue light of the invention
Most of blue light in LED light source can targetedly be absorbed by absorbing ingredient cumarin 540, while be emitted by fluorescent radiation
Green light and yellow light out can make the total brightness of light source decay to supplement the loss of light-source brightness caused by blue light is absorbed
It is smaller, the view object clarity of user is not influenced, and light source is shallow white through injection light of the invention, will not be to user's
Color judgement impacts.
Specific embodiment
Below with reference to examples illustrate the present invention and analysis.
A kind of lampshade with anti-blue light coating, the surface of the lampshade are attached with anti-blue light coating, and the anti-blue light applies
Layer with a thickness of 100-150 microns, the constituent of the anti-blue light coating indicates by weight percentage: the perfume (or spice) of 0.1-0.5%
Legumin 540, the Nano silver grain of 0.1-0.5%, the acrylic emulsion of 10-20%, the styrene-acrylic emulsion of 10-20%, 40-50%
Transparent powder, 1-5% dipropylene glycol methyl ether, 2-6% dipropylene, the dimethylethanolamine of 0.1-0.5%, 0.2-0.8%
Wetting dispersing agent, the defoaming agent of 0.1-0.5%, the thickener of 0.1-0.5%, 10-15% deionized water.
The anti-blue light lampshade made based on coating technique is compared, main blue light absorption ingredient cumarin 540 of the invention can
Targetedly to absorb most of blue light in LED light source, while green light and yellow light are launched by fluorescent radiation, to mend
The loss of light-source brightness caused by blue light is absorbed is filled, the total brightness of light source can be made to decay smaller, not influence user's
Depending on object clarity, light source is shallow white through injection light of the invention, will not judge to impact to the color of user.
The Nano silver grain is uniformly distributed in the anti-blue light coating, Nano silver grain have sterilization, antifouling, deodorization,
Self-cleaning good characteristic, therefore the present invention also advantageously improves indoor environmental condition, protects human health.
The acrylic emulsion and styrene-acrylic emulsion can respectively separately as film forming matter, but the water resistance of styrene-acrylic emulsion,
Alkali resistance is better than acrylic emulsion, and the resistance to ag(e)ing of acrylic emulsion is better than styrene-acrylic emulsion, therefore the present invention is by propylene yogurt
Liquid and styrene-acrylic emulsion mix the main film forming substance as anti-blue light coating in proportion, and the anti-blue light coating of lampshade is made to have both the two
The advantages of.
As coalescing agent, environmental-protecting performance is superior for the dipropylene glycol methyl ether, dipropylene, and compatibility is good, is easy
It is absorbed by latex particle, the membrane formation mechanism of the acrylic emulsion and styrene-acrylic emulsion can be improved, accelerated film forming speed, have simultaneously
Have the advantages that volatility is low, volatilizees, will not be had any impact after film forming to the characteristic of lampshade.
The dimethylethanolamine is as neutralizer, and main function is the solidification speed for improving anti-blue light coating in the present invention
Degree and stability.
For the transparent powder as filler of the invention, selecting fineness is that the transparent powder of 800 mesh or more can make film forming more
Uniform and smooth.Transparent powder can enhance the hardness of lampshade anti-blue light coating, be obviously improved scratch resistance and wearability, and oil factor is low,
The dosage of acrylic emulsion and styrene-acrylic emulsion can be saved, production cost is reduced, moreover, the excellent in optical properties of transparent powder, can inhale
Receiving portions blue light, faint delustring but do not influence coating transparency.
The present invention does not have special limitation to the wetting dispersing agent, defoaming agent and thickener, using those skilled in the art
Reagent known to member.
A method of the lampshade with anti-blue light coating being prepared, steps are as follows: first by the deionized water, profit
250r/min middling speed in Scattered Kettle, which is added, in hygroscopic water powder, defoaming agent disperses 5 minutes, then institute is added in the transparent powder, talcum powder
400r/min high speed dispersion 30-45 minutes in Scattered Kettle are stated, next by the cumarin 540, Nano silver grain, propylene yogurt
Liquid, styrene-acrylic emulsion are added in the Scattered Kettle 400r/min high speed dispersion 10-15 minutes, finally adjust the Scattered Kettle revolving speed
For middle and slow speed of revolution 150r/min, it is slowly added into the dipropylene glycol methyl ether, dipropylene, dimethylethanolamine, thickening
Agent, after raw material adds, the Scattered Kettle keeps middle and slow speed of revolution 150r/min stirring to can be prepared by anti-blue light painting after ten minutes
Material, it is attached by the films mode such as spraying, roller coating, dip-coating, erasing by the anti-blue light coating according to the different shaping of the lampshade
In the cover surface, can be prepared by the lampshade with anti-blue light coating.
