Description
Technical field
The present invention relates to modifying polyamide polymers compositions field, more particularly to a kind of reflecting plate polyamide compositions
Thing.
Background technology
LED is because it exceedes many advantages of conventional light source and is increasingly being used as light source.LED generally with white heat
Light source is compared with other light sources, is consumed less power, is required lower operating voltage and has to mechanical shock good
Resistance.Therefore, LED/light source is positive in many purposes substitutes incandescent source and other light sources and has been used to the neck that differs
In domain, such as traffic signals, inside and outside illumination, mobile phone display screen, automobile display screen and flash lamp.
LED component, such as shell and reflection support require that material has excellent colour stability and high temperature resistance discolouration.,
Ceramics can meet requirements above, but not only price is high but also needs higher working process technology for ceramics, and processing efficiency is low.Thermoplastic
Property polymer because it may be used as injection molding, it is succinct, flexibly, efficiently, therefore polymer composition has been carried out widely
Research and develop to substitute ceramics as the material of lower cost.The requirement of LED reflection stent applications has good light tight
Property and outstanding reflection characteristic.But generally thermoplastic polymer is easy to jaundice when in light and high temperature.For example sealed in LED
During dress, LED parts are heated at about 180 DEG C so as to cured epoxy resin or silicon encapsulant.Carrying out reflow soldering
During operation, at a temperature of LED parts are also exposed to higher than 260 DEG C.In addition, in use, LED light source block such as automobile is big
Lamp, temperature in use is higher than 80 DEG C of temperature.This exposure in high temperature causes the polymer group for forming LED parts
The jaundice of compound.
Therefore the thermoplastic polymer composition applied to LED reflection support, it should meet and a variety of require to include high light
Reflectivity（The reflectivity of visible ray）, high whiteness, good machinability（Such as good moldability）, high size
Stability（Low linear expansion coefficient）, high mechanical strength and high heat resistance（It is low when exposed to high temperature to fade and low
Reflection loss）.
As it was previously stated, in LED encapsulation process, LED component is heated to certain temperature so that silica gel solidifies.This is LED
The essential link of encapsulation, and be vital link.Research is found, is easy to produce silica gel solid in this process
Change the problem of not solidifying completely even not exclusively, causing the production process in later stage can not be carried out, and product can not be used.For how
LED reflection support is solved the problem of whiteness and reflectivity decline when in light and heat, has more patent and document to enter
Row description；But rarely have and refer to the problem of silica gel solidifies in LED encapsulation process, more do not refer to LED reflection support to silica gel solid
The influence of change.
The content of the invention
The silica gel solidification occurred in order to solve LED component to be easy in encapsulation process can not exclusively or even completely consolidate
The technical problem of change, can realize that later stage silica gel solidifies complete reflecting plate polyamide it is an object of the invention to provide one kind
