With the polymer composition of light " Chinese invention patent application divisional application.
Technical field
The present invention relates to a kind of polymer compositions of resistance to light and heat.In particular it relates to a kind of combination of polymers
Object, the polymer composition include at least one polyester, at least one hindered amine compound and at least one three valent phosphors chemical combination
Object, the trivalent phosphorous compound are to be selected from the group consisting of: phosphorous acid esters, phosphiinic acid ester and its mixing
Object.
Invention further provides the article comprising composition of the invention, such as the one of light emitting diode (LED) device
Part.
Background technique
LED is used as light source since it is more than many advantages of conventional light source in extensive application more and more.LED is total
Significant less power is consumed on body compared with incandescent source and other light sources, requires low operating voltage and to mechanical shock
With resistance.Therefore, they are many with just substitution incandescent source and other light sources and having been used to such each on the way
In different field, such as traffic signals, inside and outside illumination, mobile phone display screen, automobile display screen and flash lamp.
LED component, as shell, reflector and reflector panel require the special of excellent color and improved physical characteristic
The combination of high request.Ceramics can be advantageously used in these applications, but ceramic or extremely expensive and needs have height
It is required that processing technique.Therefore, polymer composition is conducted extensive research and is developed so as to the material as lower cost
Material is to substitute ceramics.One significant benefit of polymer is that they can be injection-molded and thus provide considerable design
Flexibility.LED application requirement has the polymer composition of good opaqueness and outstanding reflection characteristic.About for manufacturing
The problem that the polymer composition of LED component is noticed is that they are easy to turn to be yellow when being exposed in light and high temperature.Example

When operation, at a temperature of LED component is also exposed to higher than 260 DEG C.In addition, in use, LED component such as automobile component is pressed
Convention is subjected to the temperature higher than 80 DEG C.This exposure in high temperature causes the combination of polymers for being used to form LED component
The jaundice of object.
It is desirable that the reflector panel of LED and the last polymer composition for also manufacturing them, it should meet a variety of
It is required that notably including high light reflectivity (the generally reflectivity of visible light), high whiteness, good processable
Property (for example, good moldability), high dimensional stability (being notably low linear expansion coefficient), high machinery
Intensity, high heat deflection temperature and high heat resistance (low colour fading and low reflection loss when being exposed to high temperature).
Unfortunately, the various prior art polymer compositions used in LED application are when being exposed in light and heat
It is easy to turn to be yellow.
WO 2007/033129 discloses light-emitting diode component shell, these shells include poly- (terephthalic acids Isosorbide-5-Nitrae-ring
Hexane diformazan alcohol ester) (PCT) composition.More specifically, WO 2007/033129 is related to light-emitting diode component outer casing composition,

At least one inorganic strengthening agent or filler and at least one oxidisability stabilizer from 0 to 3wt.%, wherein these are heavy
Measuring percentage is the total weight based on the composition.
It will be appreciated by those of ordinary skill in the art that the further improvement pair of thermal stability, molding performance and reflectivity
It is advantageous in the development of LED component.
The inventors have found that two kinds of presence for being especially added with agent greatly strengthen polymer blend in a collaborative manner
Be subjected to and meanwhile light and heat exposure when behavior.

Albedo measurement
Behavior of the component in LED component made of composition of the invention is simulated, is by the way that sample is sudden and violent
It is exposed at 180 DEG C of light lower 12 days.Therefore, about using each composition preparation in example E4 and comparison example CE1-CE3
The disk of 50mm diameter and about 1.6mm thickness.
Disk is placed in 180 DEG C of baking ovens equipped with lamps and lanterns 12 days, the lamps and lanterns include a lamp 400W UV F/2 and
OptivexTMUV filter.With BKY-Gardner spectrometer, measure reflectivity.After the moulding on the disk of original sample and in light
With exposed 12 days under high fever (180 DEG C) after disk on reflectivity results be summarized in table 6, there are also under 460nm wavelength
Reflectivity percent retention.
Table 6: reflectivity retention rate measurement
| Reflectivity (%) under 460nm | (CE1) | (CE2) | (CE3) | (CE4) | (CE5) | (E6)(E7) |
| After molding as former state | 91.0 | 85.2 | 92.0 | 93.4 | 95.3 | 93.793.7 |
| After light and heat processing | 57.4 | 44.0 | 59.8 | 58.6 | 55.9 | 64.662.4 |
| Reflectivity retention rate (%) | 63 | 52 | 65 | 63 | 59 | 7067 |
As a result
The composition of E6 and E7 unexpectedly shows and is moulding compared with comparison example CE1 to CE5 according to the present invention
As former state and it is exposed to higher reflectivity retention rate after light and lower 12 days of high fever afterwards.
The data summarized in table 6 be well demonstrated that bi-ester of phosphite such as626 or
P-EPQ and hindered amine compound are such asThe synergistic effect observed between S-EED.Composition according to the present invention exists
It on the molded articles of original sample and is already subjected to realizing outstanding light characteristic in the identical items that light and heat is handled, at the light and heat
Reason is intended to simulate these materials may be exposed to condition therein in the manufacturing process of LED component.
Comparison example CE1 and CE3 provide evidence, it was demonstrated that individual trivalent phosphorous compound is not enough to provide with according to this hair
Bright example outstanding light characteristic obtained.
Comparison example CE2 and CE5 clearly illustrate that cannot effectively the composition be provided by only existing hindered amine compound
The enough stability when long-term (12 days) are exposed under light and high fever (180 DEG C).
Example E6 and E7 be combined with trivalent phosphorous compound (626 stabilizers orP-
EPQ) and hindered amine compound (Both S-EED), it realizes after light and high heat exposure with regard to reflectivity retention rate
For unpredictable consequence.Even if will also be obtained using the lower additive total amount compared with being measured used in CE1 and CE3
Obtain this result.
A variety of requirements that embodiment according to the present invention E6 and E7 are proposed before meeting (notably have good processable
Property, high dimensional stability, high mechanical strength) and also unexpectedly have the feature that anti-after light and heat processing
Rate is penetrated greater than 62%.Therefore these compositions are the excellent candidates for manufacturing LED component.
