Problems solved by technology

Although the existing red light LED can achieve the effect of emitting red light, the red light color rendering index produced is not high due to the disadvantages of poor thermal conductivity, poor light transmittance, obvious thermal expansion and contraction, and relatively long life. Not long, the color area is discrete, it is difficult to guarantee product quality and meet the requirements of mass production

Abstract

The invention belongs to the technical field of adhesives and preparation, and provides glue for a red light LED lamp and a preparation method thereof. The glue for the red light LED lamp comprises acomponent A and a component B. The weight ratio of the component A to the component B is 1: 1-2, and the component A comprises 40-60 parts of low-viscosity epoxy resin, 0.15-0.6 part of a curing agent, 2-4 parts of graphene and 1-3 parts of an antioxidant, and the component B comprises 20-40 parts of silica gel, 20-30 parts of inorganic nanoparticles and 1.5-2.5 parts of a coupling agent. The gluefor the red-light LED lamp is mixed and then filled into LDE and the like, lamp beads can be effectively protected, the two components are colorless and transparent, the light transmittance reaches 95% or above, the heat-conducting property of the glue can be effectively improved by adding graphene in the component A, and the service life of the glue is prolonged. The inorganic nanoparticles areadded into the component B, so that the stability of the glue is improved, the phenomenon of severe thermal expansion and cold contraction is avoided, the risk that the wire is broken is reduced, andother components ensure that the glue has good adhesion.

Description

technical field [0001] The invention belongs to the technical field of adhesives and preparations, and in particular relates to an adhesive for red LED lamps and a preparation method thereof. Background technique [0002] LED comes from the abbreviation of LIGHTEMITTINGDIODE in English, which means light-emitting diode. The structure of the simplest light-emitting diode includes P-type semiconductor, N-type semiconductor and the PN junction formed between them. When the current passes through the diode, charge carriers are generated at the above-mentioned PN junction, that is, electrons and Holes, electrons and holes combine and release energy in the form of photons. Adding specific semiconductor chemicals at the PN junction can make the diode emit light of a specific color, such as adding indium gallium nitride (In0.2Ga0.8N ) can produce pure blue light, adding gallium nitride (GaN) can produce green light, etc., the light-emitting diode is packaged and the positive and ne...
