Description

A kind of LED materials for filtering gold-tinted
Technical field
The present invention relates to technical field of polymer materials, and in particular to a kind of LED materials for filtering gold-tinted and its preparation side Method.
Background technology
The worsening reality of prior art energy crisis, greenhouse effects and ecological environment, promotes people to find energy-conservation Illuminate substitute.Light emitting diode (LightEmittingDiode, LED), because its small volume, long lifespan, colour developing are abundant and prominent Many advantages, such as energy-conserving and environment-protective characteristic gone out, obtains increasingly extensive application in fields such as display, traffic, electrical equipment and illuminations, is me One of key technology of state's energy-saving and emission-reduction, clean manufacturing and sustainable development.China's LED industry has begun to take shape and with good Growth momentum.But general LED is because light source is white light, and gold-tinted is also easy to produce, causes eye fatigue, it is therefore desirable to disappear Remove.In presently relevant document and patent and the report about filtering gold-tinted in LED is had not seen, and in traditional glass production technology Reach similar effect using neodymia rare earth, but because LED material category is more, there are the materials such as PC, PMMA, PCTG, The refractive index of material is different, causes modified material transmissivity and mist degree gap larger, therefore the extinction filler for finding matching shows Obtain particularly important.
The content of the invention
In order to overcome shortcoming and defect present in prior art, it is an object of the invention to provide a kind of filtering gold-tinted The excellent in optical properties such as LED materials, the filtering gold-tinted of LED materials of the filtering gold-tinted that the present invention is produced, light transmittance, mist degree, It can effectively filter and eliminate gold-tinted caused by LED, mitigate relieving eye strain, protect eyes, eyes is exempted from gold-tinted injury. Another object of the present invention is to provide a kind of preparation method for the LED materials for filtering gold-tinted, material preparation method technique letter Single, convenient operation and control, steady quality, high yield rate, production efficiency is high, and production cost is low, can large-scale industrial production.
The purpose of the present invention is achieved through the following technical solutions：
A kind of LED materials for filtering gold-tinted, it includes the raw material of following mass parts：
Base material 60-100 parts,
Phytosterol 1-13 parts,
Ultra-violet absorber 0.1-1.0 parts,
Stannous octoate 0.1-0.8 parts,
Dispersant DP310 0.2-0.4 parts,
Deionized water 2-26 parts,
Wherein, the phytosterol is one or more kinds of in expoxy propane, neodymia, polyvinyl alcohol and glass fibre Mixture.
Preferably, the LED materials of described a kind of filtering gold-tinted, it includes the raw material of following mass parts：
Base material 70-90 parts,
Phytosterol 5-10 parts,
Ultra-violet absorber 0.2-0.8 parts,
Stannous octoate 0.3-0.6 parts,
Dispersant DP310 0.2-0.4 parts,
Deionized water 10-20 parts,
Wherein, the phytosterol is one or more kinds of in expoxy propane, neodymia, polyvinyl alcohol and glass fibre Mixture.
The present invention uses DP310 effectively to reduce nethike embrane blocking as dispersant, lower the back-pressure in extruder and reach To processing more efficiently；Screw speed can be increased in processing, while can also reach more preferable dispersive property；Can be effective Pigment agglomerates are broken up, reduce spot, increase material glossiness；It can bring product more stable quality, reduce tie rod fracture Occur, so as to reduce percent defective, improve the quality of material, reduce production cost.
Preferably, the base material is one kind in PC, PMMA, COP, PETG, PCTG, ABS, PS and AS.
Preferably, the ultra-violet absorber is organosilicon ultra-violet absorber or acrylate ultra-violet absorber.Have Machine silicon ultra-violet absorber or acrylate ultra-violet absorber, the relatively general ultra-violet absorber of organosilicon ultra-violet absorber With efficiency high, heat resistance especially protrusion, the control of chromaticness stabilization, non yellowing, particle microscopic pattern is finer, particle diameter distribution is narrow Significant advantage, material mechanical performance and interior impact property are excellent.
Preferably, the stannous octoate is 1076 and 168 mixture.1076 oxidants and the collaboration of 168 oxidants use, Volatility is low, and hydrolytic resistance is outstanding, can effectively prevent the change of molecular weight caused by oxidative degradation in mixing and granulation process（Such as Chain rupture and crosslinking）, prevent color change.
A kind of preparation method for the LED materials for filtering gold-tinted, comprises the following steps：
Step A, the deionized water and phytosterol for taking prescription quality part are dispersed in large beaker, are heated to 80-90 while stirring DEG C, reach target temperature after, static isothermal holding 1.5-2.5h, then air cooling dry, until supernatant surplus is 8-12ml When, directly supernatant is outwelled, the residue in large beaker is transferred to place in baking oven in iron ware and toasted, toasts drying After the completion of, the powder of gained is taken out, is cooled to room temperature, it is standby；
Step B, the standby powder in the ultra-violet absorber, stannous octoate, DP310 and step A of prescription quality part is taken to add respectively Enter in homogenizer and mixed, to after being thoroughly mixed, stop stirring, take mixed powder standby；
Step C, by mixed powder obtained by step B and the resin of prescription quality part is taken to add high speed machine, after being uniformly mixed, Extruding pelletization in extruder.
Preferably, the drying process mode in the step A is：The residue first is placed in into 110-130 DEG C of baking oven to dry Roasting 11-13h, then go to 290-310 DEG C of baking oven baking 22-26h.
Because after supernatant is outwelled, residual moisture is still relatively more, may be acutely now if too high-temperature toasts Boiling, iron ware is gone out, 110-130 DEG C is mainly removed free water；290-310 DEG C is in order to which further remove may be with The deionized water of Hydrogenbond, two steps are different because extrusion or injection ceiling temperature at 300 DEG C, if water at a temperature of this Can't get out just does not influence on system, so only needing to remove less than 310 DEG C of moisture.
Preferably, the agitating mode in the step B stops 30s often to stir 3min, and it is extremely complete so to repeat stirring 4-6 time After full mixing, stop stirring.By batch type, material mixing is more abundant, and mixing is more uniformly distributed.Stirred using intermittence The advantages of be：Because continuously stirring, quickly, interior heat can cause material to have certain degraded to heat, and this material belongs to optical material, Slight change can all produce certain influence to follow-up spectrogram, and the degraded of material is avoided using batch type.
Preferably, a kind of preparation method for the LED materials for filtering gold-tinted, five sections of extrusion temperatures difference of the extruder It is：One area's temperature is 200-230 DEG C, and two area's temperature are 210-230 DEG C, and three area's temperature are 210-230 DEG C, and four area's temperature are 210- 265 DEG C, five area's temperature are 210-260 DEG C, and the rotating speed of the extruder is 360-440r/min.
