The invention discloses a single-
package organic
silicon rubber packaging
adhesive for a high-power type white LED (light-emitting
diode) and a preparation method of the single-
package organic
silicon rubber packaging
adhesive. The preparation method of the single-
package organic
silicon rubber packaging
adhesive for the high-power type white LED comprises the following steps: uniformly stirring 100-120 parts by weight of high-
viscosity self-crosslinked phenyl organic
silicon rubber, 0.001-0.005 part by weight of a catalyst, 0.002-0.005 part by weight of an inhibitor and 4-8 parts by weight of a reinforcing agent; and, then, deaerating the components in vacuum for 15-30 minutes to obtain the single-package organic
silicon rubber packaging adhesive, with a high
refractive index and high light
transmittance, for the high-power type white LED, wherein the single-package organic
silicon rubber packaging adhesive is transparent after being cured, and has
shore A
hardness of 53-77. The preparation method is simple, environment-friendly and efficient. The single-package organic silicon rubber packaging adhesive is used for
high polymer material fields such as high-power
LED packaging, is used for filling and sealing of electrical elements, filling and sealing of high-pressure parts and
moisture-proof
coating of circuit boards, packaging, insulation protection and the like of electronic LED indoor and outdoor display panels, LED traffic signals, and the like.
