▎ 摘  要

NOVELTY - Glue comprises component A comprising 40-60 pts. wt. low-viscosity epoxy resin, 0.15-0.6 pts. wt. curing agent, 2-4 pts. wt. graphene and 1-3 pts. wt. antioxidants, and component B comprising 20-40 pts. wt. silica gel, 20-30 pts. wt. inorganic nanoparticles and 1.5-2.5 pts. wt. coupling agent. USE - The glue is useful for red LED lights (claimed). ADVANTAGE - The glue: protects the lamp beads; is colorless and transparent; has light transmittance of more than 95%; increases the thermal conductivity; improves the stability of the glue; does not have severe thermal expansion and contraction; reduces the risk of wire breakage; and ensures that the glue has excellent adhesion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the glue, comprising (i) taking 40-60 pts. wt. low-viscosity epoxy resin, 0.15-0.6 pts. wt. curing agent, 2-4 pts. wt. graphene and 1-3 pts. wt. antioxidant, and stirring and heating at 100-120 degrees C until the graphene is completely dissolved to obtain the component A, and (ii) taking 20-40 pts. wt. silica gel, 20-30 pts. wt. inorganic nanoparticles and 1.5-2.5 pts. wt. coupling agent, and uniformly mixing to obtain component B.
