Abstract

The invention relates to a double-component transparent epoxy resin LED (light emitting diode) patch packing adhesive. The double-component transparent epoxy resin LED patch packing adhesive is characterized by consisting of two components, namely an A component and a B component, wherein the A component and the B component are mixed to be applied to construction according to the proportion of 1:(0.9-1.0), the A component consists of cycloaliphatic epoxy resin, silicone resin intermediate, reactive diluent, transparent blue and purple dye color paste, a defoaming agent and a flexibility agent, and the B component consists of a curing agent, an accelerating agent, an ultraviolet absorbent, polyalcohol and an antioxidant. The invention provides transparent cycloaliphatic epoxy resin patch adhesive with small viscosity, strong cohesive force, difficulty in cracking, high temperature resistance, high corrosion resistance and low temperature resistance, overcomes the defects that the current epoxy resin patch adhesive has brittleness, high hygroscopicity, low light transmittance, poor ultraviolet resistance and the like, is more suitable for outside LED and high-power LED packing adhesive, has the advantages of being simple in manufacturing process, lower in production cost and advanced technique in country, and is suitable for industrial large-scale production.

Description

technical field [0001] The invention relates to an LED chip packaging glue, in particular to a two-component transparent epoxy resin LED chip packaging glue. Background technique [0002] Light-emitting diodes (LEDs), as the third-generation semiconductor lighting source, are widely used in lighting, radiation sources, and displays because they have advantages in all aspects compared with incandescent lamps and fluorescent lamps. LED packaging materials must have high light transmittance, refractive index, excellent processability, moisture resistance, solvent resistance, thermal discoloration resistance, UV aging resistance and other necessary mechanical and thermal properties. [0003] With the development of the electronics industry, electronic appliances are developing toward miniaturization, light weight, multi-function, and high performance, and the application of surface mount technology SMT is becoming more and more common. Surface mount technology, its process invo...
