| titleOfInvention | A kind of high refractive index LED liquid casting glue tackifier and preparation method thereof |
| abstract | The present invention provides high refractive index LED liquid casting glue tackifier and preparation method thereof, the preparation method is using the organosiloxane with hydrolyzable alkoxy grp as monomer, under organic solvent dispersion, cohydrolysis polycondensation under the action of catalyst, a kind of water white transparency polymethyl-benzene base silicones oligomer solution is obtained after washing, then by polymethyl-benzene base silicones oligomer solution and with active function group silane coupling agent, under the effect of the catalyst, ester exchange reaction occurs, after filtering or catalyst neutralisation, after removed under reduced pressure lower-molecular substance, a kind of suitable high refractive index LED liquid casting glue tackifier are prepared.The tackifier refractive index of the present invention is greater than or equal to 1.50, has good compatibility with high refractive index LED liquid casting glues.The present invention has many advantages, such as simple for process, reproducible and structural controllability.The tackifier of the present invention can play an important role in the encapsulation field of LED light emitting diodes. |
