Description
Technical field
The present invention relates to silicone resin technical fields, are to be related to a kind of vinyl polysiloxane and its preparation side more specifically
Method and application.
Background technique
Light emitting diode (LED) is referred to as forth generation lighting source, since it is long, small in size with the service life, low energy consumption, opens
The advantages such as dynamic fast, luminous efficiency height, be widely used to liquid crystal display, illumination, traffic lights, detector, electronic equipment, etc.
Field.
Organosilicon material has many advantages, such as excellent heat-resisting and ultraviolet light and aging performance, and high transparency, low internal stress are recognized
To be ideal LED encapsulation material, just gradually substituted epoxy resinae encapsulating material, wherein the high refractive index silica gel containing phenyl
(refractive index > 1.5) has higher smooth extraction efficiency, more preferably high-low temperature resistant, resistance to vulcanization, the resistance to performances such as ultraviolet.But by
It is unsatisfactory in pure organic silica gel itself and the adhesive effect of LED support substrate, how to improve the viscous of LED packaging silicon rubber and substrate
Effect is connect, is always that silica gel producer and research institution research and develop improved direction, lamp bead can be improved in the raising with substrate bonding power
Impact, it is resistance to infiltration, it is resistance to vulcanization etc. performance indexess.
In recent years, the patent of invention for improving LED packaging silicon rubber bonding force gradually increases.It wherein, is greatly logical
The cementability for adding related tackifying assistant to improve silica gel is crossed, this method exists and base rubber poor compatibility, Yi Yinqi catalyst poisoning
The problems such as.As the Chinese patent of Publication No. CN103805128A disclose a kind of high refractive index LED packaging plastic bonding agent and
Its synthetic method, this method is using organotin catalyzed terminal hydroxy group methyl vinyl phenyl silicone oil and KH560 dealcoholization condensation reaction system
Standby tackifier；But the tackifier be used for LED packaging silicon rubber when, organotin therein may make to lead to Pt catalyst poisoning,
Influence solidification.For another example the Chinese patent of Publication No. CN106008983A discloses a kind of silicon boron tackifier, Publication No.
The Chinese patent of CN106397771A discloses a kind of containing acrylate-based, epoxy group organic silicon rigidity-increasing stick；But such increasing
The index of refraction of stick is lower, using muddy the case where whitening is easy to appear in high refractive index silica gel, to will affect product
Transparency.In addition, being to improve the bonding force of silica gel by increasing the bonding group in base rubber molecule, but prepare there are also one kind
Process is relative complex, and technology stability is not good enough, is easy to get the product of applied defect.Such as Publication No. CN108384010A
Chinese patent discloses a kind of epoxidation modification methyl phenyl silicone resin and preparation method thereof, and this method uses 3- glycidol ether
Oxygroup hydroxypropyl methyl dimethoxysilane and aminomethyl phenyl dimethoxysilane are raw material, pass through hydrolysis-condensation reaction synthesizing epoxy
Change modifying methylphenyl silicone resin；But the preparation of this method is the molecule of D structure, structure is relatively simple, has in practical applications
Certain limitation.For another example the Chinese patent of Publication No. CN104877138A discloses a kind of silicone resin with adhesive property
And preparation method thereof, this method uses trialkoxy silane, dialkoxy silicane, epoxy group hydrocarbyl si lanes, acryloxy silicon
Alkane, boron-containing compound and end-capping reagent are reacted under the action of acid as catalyst under water and organic solvent environment, by drift
It washes, dry, obtained colorless and transparent organic siliconresin；But a variety of alkoxy silanes hydrolyze together in this method, due to various
Alkoxy silane hydrolysis rate is different, is easy to get the wide product of mixed and disorderly molecular structure and molecular weight distribution, and urge in acid
Effective dehydrating condensation process is not carried out after changing hydrolysis, is easy that there are a certain amount of silicone hydroxyls in resulting silicone resin, especially
In the biggish phenyl polysiloxane of preparation steric hindrance, the silicone hydroxyl contained in silicone resin will affect the properties of packaging silicon rubber.
In conclusion developing, a kind of preparation process is simple, stablizes, good compatibility and silicon tree with Efficient Adhesive Promotion itself
Rouge, can not only save the process and risk of addition tackifying assistant, but also packaging silicon rubber can be improved to the cementability of substrate, become this
Field technical staff technical problem urgently to be resolved.
