Abstract

The invention relates to the field of ink and particularly relates to yellowing-resistant photosensitive solder resist ink and a preparation method thereof. The yellowing-resistant photosensitive solder resist ink is prepared from the following components in parts by mass: 50-150 parts of beta-hydroxyethyl acrylate modified melamine-formaldehyde resin, 40-120 parts of reaction diluent, 5-15 parts of polysilazane resin, 15-50 parts of epoxy resin, 4-12 parts of photoinitiator, 120-200 parts of pigment, 4-10 parts of filler and 4-10 parts of auxiliary. The invention provides yellowing-resistant photosensitive solder resist ink for an LED (Light Emitting Diode); compared with the traditional home-produced photosensitive solder resist ink, the solder resist ink prepared by the invention has the advantages of high reflectance and excellent heat resistance, soldering resistance and yellowing resistance, and is particularly suitable for being used as photosensitive solder resist ink for the LED.

Description

technical field [0001] The invention relates to the field of inks, in particular to an anti-yellowing photosensitive solder resist ink and a preparation method thereof. Background technique [0002] At present, China's LED market demand has reached 87.57 billion. In the next three to five years, the market's demand for LEDs will continue to grow. It is estimated that by 2015, China's LED market demand will reach 192.74 billion, and the market size will reach 40.67 billion yuan; from 2013 to 2015, the average annual compound growth rate of China's LED market will reach 14.3%. The growth of the LED market will continue to expand the demand for liquid photosensitive solder resist inks for LEDs. [0003] The substrate used to install LEDs is also called aluminum substrate, which is a metal-based copper clad laminate with good heat dissipation function. It consists of a unique three-layer structure, which is a circuit layer (copper foil), an insulating layer and a metal base lay...
