Abstract

The invention discloses a tackifier, a silicone packaging glue composition and a silicone packaging glue. The tackifier is used for silicone encapsulation, and the tackifier is formed by a borosiloxane polymer, and the general formula of the borosiloxane polymer is expressed as: (R 1 R 2 2 SiO 1 / 2 ) x (R 2 R 3 SiO 2 / 2 ) y (R 3 SiO 3 / 2 ) z (SiO 4 / 2 ) i (BO (3‑k) / 2 ) j (OR 4 ) k . Among them, R 1 is a hydrogen atom or an alkenyl group with a carbon number of 2 to 6, R 2 and R 4 Each is independently an alkyl group with a carbon number of 1 to 6, and R 3 It is an aromatic group having 6 to 12 carbon atoms. Wherein, x, y, z, i, j and k each independently represent a mole fraction, x, y, z, i and j are each independently a non-negative number less than or equal to 1, x+y+z+i=1 and x is greater than 0.

Description

technical field [0001] The invention relates to a tackifier and its application, in particular to a tackifier used in the field of light-emitting diode packaging and its application. Background technique [0002] Light-emitting diodes (light-emitting diodes, LEDs) are semiconductor components that can efficiently convert electrical energy into light energy, and have the advantages of long life and power saving. Therefore, light emitting diodes are widely used in various products. [0003] In order to protect the LED and make it possible to assemble the LED with other components in the future, the LED will be packaged first after manufacture. During the packaging process, the light-emitting diodes are arranged on a frame to be connected with external circuits. In addition, the light-emitting diode is also covered by a packaging material to prevent external water vapor from infiltrating and contacting the light-emitting diode, thereby achieving the effect of prolonging the s...
