Abstract

The invention discloses an epoxy resin composition for a high heat-resisting aluminum substrate as well as a preparation method and application of the epoxy resin composition. The epoxy resin composition for the high heat-resisting aluminum substrate is prepared from the following raw material components in parts by weight: 55 to 65 parts of phenolicepoxy resin, 20 to 24 parts of phenolic resin and 17 to 21 parts of a diluent. An LED (Light-Emitting Diode) aluminum substrate circuit board prepared by the epoxy resin composition for the high heat-resisting aluminum substrate has the advantagesof higher heat resistance, and the capabilities of meeting the requirement of welding processing on heat resistance and ensuring the reliability of welding.

Description

technical field [0001] The invention relates to an epoxy resin composition for an aluminum substrate, in particular to a preparation method of an epoxy resin composition for a high heat-resistant aluminum substrate and an LED aluminum substrate circuit board. Background technique [0002] Generally, the material of the circuit board is glass fiber, but because the LED generates a lot of heat, the circuit board used in the LED lamp is generally an aluminum substrate, which can conduct heat quickly. [0003] The aluminum substrate generally adopts bisphenol A type epoxy resin to react with a curing agent, and the heat resistance of the prepared aluminum substrate is not very good. For circuit board processing and soldering assembly, lead-free soldering of circuit boards will become a foregone conclusion. The melting point of solder is higher than that of lead-containing solder. In order to ensure the reliability of soldering, the materials to be soldered must have higher heat ...
