Description
Technical Field
The invention relates to the technical field of thermosetting packaging molding materials, in particular to a prepolymer, packaging resin containing the prepolymer and application of the packaging resin.
Background
As a light Emitting semiconductor, an led (light Emitting diode) has become an irreplaceable photoelectric device in the fields of illumination, active RGB display, LCD backlight, vehicle lighting, and the like. The LED lighting and RGB display device packaging mostly adopts an LED packaging structure that a reflecting cup is pre-molded on a resin substrate and a metal support, then liquid packaging materials are poured or filled in the reflecting cup in a dispensing mode, and the packaging materials and the reflecting cup are integrated after thermal curing. The reflecting cup is a carrier of a liquid packaging material, and simultaneously bears the light emission of the reflecting LED chip to form an upward direct-emitting (Top View) single-side light-emitting structure. The white light illuminating device adopts a white reflecting cup package to enhance the light extraction efficiency, and the RGB display device adopts a black reflecting cup to improve the contrast ratio of the display.
The white light LED adopts a blue light chip with the emission wavelength of 450-470nm as a light source, yellow light is emitted by exciting yellow fluorescent powder mixed in the packaging resin, and finally the yellow light and the blue light are synthesized into white light. PPA (polyphthalamide resin) materials are used for the first time as the reflecting cup of the white light device, and the PPA (polyphthalamide) materials are used as thermoplastic materials, so that the PPA materials are easy to injection mold, strong in flexibility, low in cost and the like, and are very suitable for packaging low-power white light LEDs of 0.5-1W. And the blue light chip has strong photodegradation effect on PPA resin to cause yellowing of the material, so that the reflectivity of the reflective cup material is reduced, and the light emitting of the LED chip is damaged. In addition, when the white light LED chip is applied to a lamp, the reflow soldering surface mounting process at the high temperature of 260 ℃ at most needs to be carried out, and the thermoplastic PPA is easy to generate deformation and thermal expansion stress at the high temperature to damage the LED lamp bead.
Later on, thermosetting epoxy resin reflecting cup materials taking triazine derivative epoxy resin or alicyclic epoxy resin as a core component appear on the market, and are called as 'EMC supports'. The epoxy resin does not contain a benzene ring structure, so that the blue light resistance of the EMC bracket is greatly improved compared with that of a PPA material, the reflow soldering resistance and thermal deformation resistance are also excellent due to the thermosetting material, and the white light chip packaged by the material is called as an EMC lamp bead by the industry. Although the EMC reflector cup holder has obvious advantages of blue light resistance and heat resistance compared with PPA thermoplastic materials, the blue light resistance problem still exists in the LED products with stronger power (2-3W), and yellowing of epoxy resin is still a major focus problem under long-term high temperature and blue light irradiation.

The present invention is described below by way of specific embodiments, but is not limited to the specific embodiments given below.
In order to solve the above problems, a first aspect of the present invention provides a prepolymer prepared from the raw materials comprising:
(A) a compound having a structure as shown in formula 1, formula 1:wherein R is1、R2、R3Each independently selected from vinyl or epoxy;
(B) organosiloxanes containing phenyl and Si-H groups;
(C) a platinum catalyst.
In some preferred embodiments, R is1、R2、R3At least one of which is vinyl; further preferably, R is1、R2、R3At least one of which is a vinyl group and at least one of which is an epoxy group.
As examples of (A) the compound having a structure represented by the formula 1, DA-MGIC (diallyl monoglycidyl isocyanurate, CAS number: 20395-16-8), MA-DGIC (monoallyl diglycidyl isocyanurate, CAS number: 69731-45-9) are specifically exemplified.
In some preferred embodiments, the phenyl group in the (B) organosiloxane having phenyl and Si — H groups is located in a side chain of the organosiloxane.
In some preferred embodiments, the (B) organosiloxane containing phenyl and Si-H groups has Si-H groups located in the side chains and/or end groups of the organosiloxane.
The organosiloxane of the present invention may be commercially available, for example, RH-309 manufactured by Ningbo Runza Gaoka materials science and technology Co., Ltd, a benzene-based crosslinking agent series product manufactured by Anbia Special Silicone (Nantong) Co., Ltd, and the like.
In some preferred embodiments, the molar ratio of the Si-H group content in the (B) phenyl and Si-H group-containing organosiloxane to the vinyl group content in the (A) compound having the structure shown in the formula 1 is (0.2-1): 1; more preferably, the molar ratio of the Si-H group content in the phenyl and Si-H group-containing organosiloxane (B) to the vinyl group content in the compound (A) having the structure shown in the formula 1 is (0.25-0.95): 1.
in order to solve the problem that the packaging epoxy resin is easy to yellow in an LED product, the inventor introduces a siloxane structure into the material, and because the Si-O-Si siloxane structural bond energy of the organic silicon is larger than the C-C bond energy of the epoxy resin, the yellowing can be effectively improved, and meanwhile, the heat resistance of the material is improved, however, the organic siloxane and the epoxy resin have larger property difference, and the compatibility between the organic siloxane and the epoxy resin is poor. The inventor finds that the compatibility of the organic siloxane in an epoxy resin system can be greatly improved by preparing a prepolymer from a specific epoxy compound and the organic siloxane and introducing the prepolymer into the packaging resin, so that the operating performance and the UV resistance of the packaging resin are improved. The inventor has further unexpectedly found that the organosilicon containing phenyl groups is beneficial to reducing the processing viscosity of the packaging resin and facilitating the packaging operation, the phenyl groups are easy to be oxidized to form quinone, the material is yellowed, however, the steric effect of the phenyl groups can reduce the interaction force among molecular chains and increase the migration performance of the molecular chains, and therefore, in order to balance the operability and the UV resistance of the material, the proportion of the raw materials of the prepolymer needs to be controlled within a certain range.
