Abstract
The present invention provides a kind of high folding packaging plastics of the reliable LED of cohesive, is made up of the material of following mass percentage content：Phenyl vinyl MT resins (ethylene contents for 3% 9%) 45~80%, phenyl-vinyl silicon oil 10~30%, platinum group catalyst 0.02~0.04%, tackifier 0.5~2%, benzene cross-linking agent 5~25%, inhibitor 0.1~0.5%.The beneficial effects of the present invention are have excellent adhesive property and cold-resistant thermal shock resistance properties, sulfidation-resistance energy, resistance to elevated temperatures, and cost is relatively low.
Description
Technical field
The present invention relates to a kind of high folding packaging plastics of the reliable LED of cohesive.
Background technology
LED light source turns into the most important light source of lighting field because it possesses the advantages that energy-efficient, green.Encapsulation
A ring essential as LED light source, the more and more higher also required its material property, such as require that closed material has and absorb
Light, do not scatter, have good cohesive with various base materials such as element, lead frame, substrate and frameworks.Hydrosilylation reactions are consolidated
The cured silicone combination of change is used as the photosemiconductor components such as photoelectrical coupler, light emitting diode, solid state image sensor most
Conventional packaging protection material, cost is relatively low, but it has cementability deficiency.
The content of the invention
To solve the above problems the invention provides a kind of high folding packaging plastics of the reliable LED of cohesive, there is excellent glue
Performance is connect, and cost is relatively low.
Technical scheme provided by the present invention is：A kind of high folding packaging plastics of the reliable LED of cohesive, by following quality percentage
Material than content is made：
The beneficial effects of the present invention are resistance to excellent adhesive property and cold-resistant thermal shock resistance properties, sulfidation-resistance energy
High-temperature behavior, and cost is relatively low.
Embodiment
Embodiment 1：
The phenyl vinyl MT resins of above-mentioned percentage by weight are weighed, phenyl-vinyl silicon oil, in reaction vessel, are stirred
Uniformly, platinum group catalyst and tackifier are added, is stirred, benzene cross-linking agent is then added, inhibitor, stirs, very
Empty deaeration, obtain the high folding encapsulation glue compositions of the reliable LED of cohesive.
Embodiment 2：
The phenyl vinyl MT resins of above-mentioned percentage by weight are weighed, phenyl-vinyl silicon oil, in reaction vessel, are stirred
Uniformly, platinum group catalyst and tackifier are added, is stirred, benzene cross-linking agent is then added, inhibitor, stirs, very
Empty deaeration, obtain the high folding encapsulation glue compositions of the reliable LED of cohesive.
Embodiment 3：
The phenyl vinyl MT resins of above-mentioned percentage by weight are weighed, phenyl-vinyl silicon oil, in reaction vessel, are stirred
Uniformly, platinum group catalyst and tackifier are added, is stirred, benzene cross-linking agent is then added, inhibitor, stirs, very
Empty deaeration, obtain the high folding encapsulation glue compositions of the reliable LED of cohesive.
Respectively by embodiment 1, embodiment 2, the composition of embodiment 3 does contrast test with two commercially available material, 5 groups
LED encapsulates glue composition dispensing or tank glue on component to be packaged, carries out light transmittance, high temperature resistant, red ink, cohesive etc.
The test of aspect, as a result as shown in table 1.
The high folding encapsulation glue composition test results of the reliable LED of the cohesive of table 1
The present invention is explained in detail above in conjunction with embodiment, but the present invention is not limited to above-described embodiment.In ability
, can also be on the basis of each composition effect basis mechanism is well understood that in the those of ordinary skill's possessed knowledge of domain
Do not depart from the premise of present inventive concept that various changes can be made, come under protection scope of the present invention.
