Definitions
- the invention relates to a transparent casting resin composition for potting optoelectronic components.
- Casting resin as a capsule and assembly material for potting optoelectronic components based on an acid-anhydride-curable epoxy compound which is produced by mixing an A component consisting of at least one epoxy compound and at least one multifunctional epoxy novolac resin, and optionally others Additives, and a B component consisting of at least one carboxylic anhydride.
- the transparent epoxy cast resin formulations according to the invention can advantageously be processed in established packaging technology and meet the optical, electrical and thermomechanical quality requirements of future product generations in optoelectronics and, above all, have glass transition temperatures above 130 ° C. According to the current state of knowledge, the toxic hazard potential of the starting materials is low, so that health risks can be excluded as far as possible.
- the A component preferably has further additives, such as a reactive thinner, an alcohol, an adhesion promoter, a leveling agent, an agent for degassing, a diffuser paste, and a component for adjusting the color number / coloring.
- additives such as a reactive thinner, an alcohol, an adhesion promoter, a leveling agent, an agent for degassing, a diffuser paste, and a component for adjusting the color number / coloring.
- an epoxy casting resin component according to the invention is preferably composed as follows:
- multifunctional epoxy casting resins ⁇ 80 wt. -%
- Diffuser paste (pigment in epoxy- ⁇ 10 wt.% Casting resin) adhesion promoter: ⁇ 5 wt. - Leveling agents: ⁇ 1 wt. -
- the carboxylic anhydride can be, for example, a hexahydrophthalic anhydride, as in DE 26 42 465.
- the glass transition temperature of a molding material from the aforementioned embodiment with a mixing ratio A: B of 100:90 is 140 ° C. Under manufacturing conditions, 135 ° C was obtained on the component. All functional and component-specific qualifications according to the latest automotive electronics standards have been passed.
- the viscosity of the epoxy resin component at 25 ° C is ⁇ 15,000 mPas.
- the viscosity of the A: B reaction resin mixture at 25 ° C is ⁇ 3,000 Pas.
- the shelf life of the epoxy cast resin component is at least 1 year at temperatures up to 30 ° C.
- the service life of the A: B reaction resin mixture at 25 ° C is at least 6 h.
- the favorable reactive behavior of the A: B reaction resin mixture enables fast curing cycles with reliable component potting in mass production processes with quantities of several 100 million per year.
- the glass transition temperature of the molding materials is> 130 ° C. Water absorption after 2 weeks of water storage at 23 ° C is ⁇ 0.5% by weight
- the transmission of a 1 mm thick molding material in the visible range of light is> 88%.
- the color shift after thermal aging 130 ° C after 6 weeks is ⁇ 10.
- the lenses produced in this way prove to be radiation-resistant in bright LEDs with, for example, 1.4 Im / 50 mA.
- the present molding material development is characterized by exceptional fracture mechanical properties, with K IC 1.34 MPaV and Gic 577 J / m 2 ; the encapsulated products can be used in all SMT processes and are also suitable for applications in the automotive sector (Tg> 130 ° C!)
- the mass reduction up to 300 ° C is ⁇ 2% (thermo balance, 10 K / min, nitrogen).
