Description
Technical field
The present invention relates to a kind of LED encapsulation material, and in particular to a kind of doped-glass fiber, the LED with fluorescent functional
Encapsulating material and preparation method thereof.
Background technology
LED organosilicon material for packaging is typically sizing material, low viscosity based on vinyl polysiloxane or vinyl silicone oil
Containing hydrogen silicone oil is cross-linking agent, then coordinates reinforced resin, diluent, catalyst, inhibitor etc., under certain condition crosslinking curing and
.With the development of the progress of LED encapsulation technologies, particularly large power white light LED, silicone encapsulating material is increasingly
Show its advantage.LED encapsulation is different from general organosilicon material with silica gel material, except to possess preferable mechanical property
Can be outer, and excellent thermostability and high transparent must be kept.The preparation of organosilicon encapsulating material adopts dual composition addition type mostly
Formula system, under conditions of Pt series catalysts are present heat cure molding is passed through.
Liu Jinlong is in its master thesis《The preparation and performance study of LED encapsulation silica gel materials》In, using ethylene
Base silicone oil and containing hydrogen silicone oil cross-linking agent are prepared for LED encapsulation silica gel materials, but also there is crack resistence performance shortcoming, do not have
The problems such as having fluorescent functional.
The content of the invention
Think deeply based on more than, the present invention is intended to provide a kind of crack resistence, and the LED encapsulation material with fluorescent functional.
The technical problem to be solved is realized using following technical scheme：
A kind of doped-glass fiber, the LED encapsulation material with fluorescent functional, it is characterised in that be by the original of following weight portion
Material is made：
Glass fibre 2-4, vinyl silicone oil 30-40, mica powder 1-2, vinyl MQ resin 8-12, dimethylbenzene 10-20, Fructus Citri Limoniae
Sour 4-8, ethylenediamine 3-6, polyvinyl alcohol 1-2, deionized water 5-10, silicon powder 5-10, Silane coupling agent KH550 6-11, it is hydrogeneous
Silicone oil cross-linking agent 25-35, chloroplatinic acid isopropanol 2-3.
Described a kind of doped-glass fiber, the LED encapsulation material with fluorescent functional and preparation method thereof, its feature exists
In being made up of following steps：
A. vinyl silicone oil, polyvinyl alcohol are put in equipped with agitator, the container of thermocouple, 80-120 DEG C is warming up to；By second
Thiazolinyl MQ resins are dissolved in xylene solution, are stirred to dissolving, in being slowly dropped to above-mentioned vinyl silicone oil, drip Bi Houji
Continuous constant temperature stirs 10-30min, and last fully desolvation obtains basic glue；
B. with citric acid as carbon source, ethylenediamine, deionized water are added, is placed 3-7 days under the conditions of 150-250 DEG C, obtained in purple
Outer light is excited down, the liquid carbon point fluorescent material with blue emission, green emission and red emission；
C. silicon powder, mica powder, glass fibre are added in step b gained liquid, add Silane coupling agent KH550, surpassed
After sound dispersion 10-30min, 3-5h is soaked, filter, wash, dry, obtain adsorbing the mixture of carbon point fluorescent material；
D. containing hydrogen silicone oil cross-linking agent and step c gained mixture are added in the basic glue of step a gained, chloroplatinic acid is then injected into
Isopropanol, vacuum defoamation 20-50 min after mix homogeneously, then respectively at 80-100 DEG C of precrosslink 0.5-2 h, 130-160
DEG C deeply-curing 1-3 h, are cooled to room temperature and obtain encapsulating material；
Described a kind of doped-glass fiber, the LED encapsulation material with fluorescent functional and preparation method thereof, it is characterised in that
In step a the condition of desolvation be temperature 120-140 DEG C, pressure -0.06 ~ -0.1MPa.
The invention has the beneficial effects as follows：Using vinyl MQ resin reinforcement vinyl silicone oil, obtained encapsulating material is heat-resisting
Property preferably, tensile strength is larger；Silicon powder adsorptivity, the dispersibility that Silane coupling agent KH550 was processed preferably, is soaked in carbon point
After in fluorescent material, carbon point fluorescent material can be adsorbed, so as to give encapsulating material can fluorescence the characteristics of, meanwhile, its uniform point
In being dispersed in silica gel packaging material, it is to avoid the directly contact of carbon point fluorescent material and LED chip, efficiently solve due to LED
Chip generates heat and causes the problem that fluorescent material rate of decay is too high, failure is too fast, and then improves the service life of LED lamps
And integrated quality；On the other hand, the introducing of silicon powder acts not only as the carrier of carbon point fluorescent material, moreover it is possible to reduce silicon materials
The exothermic peak temperature of curing reaction, reduces the linear expansion coefficient and shrinkage factor of solidfied material, so as to eliminate the internal stress of solidfied material,
Prevent cracking；By coordinating addition glass fibre, mica powder etc., heat-resisting quantity, the insulating properties of material are significantly improved.
