Abstract

The invention discloses two-component glue for blending fluorescent powder. The glue is composed of an agent A and an agent B, wherein the weight ratio of the agent A to the agent B is 1:1; the agentA is composed of the following components in parts by weight: 45-55 parts of modified epoxy resin, 43-52 parts of aliphatic epoxy resin and 1.5-3 parts of an assistant; and the agent B is composed ofthe following components in parts by weight: 97-99 parts of imported methylhexahydrophthalic anhydride and 1-3 parts of an accelerant. The two-component glue for blending fluorescent powder provided by the invention has the advantages of good adhesive strength, aging resistance, light degradation resistance, good ultraviolet resistance and the like. When applied to LED light fittings, the two-component glue for blending fluorescent powder can effectively improve the luminous quality and service life of the LED light fittings.

Description

technical field [0001] The invention relates to a glue, in particular to a two-component fluorescent powder-adjusting glue and a preparation method thereof. Background technique [0002] There are three main methods for LED lamps to use phosphor powder to achieve white light: 1. Coating yellow phosphor powder that can be excited by blue light on the blue LED chip, the blue light emitted by the chip and the yellow light emitted by the phosphor complement each other to form white light; 2. Coat green and red phosphors on the blue LED chip, and combine the blue light emitted by the chip with the green light and red light emitted by the phosphor to obtain white light; 3. Coat three primary colors or multiple colors on the purple or ultraviolet LED chip The fluorescent powder of different colors uses long-wave ultraviolet light (370nm-380nm) or purple light (380nm-410nm) emitted by the chip to excite the fluorescent powder to achieve white light emission. [0003] At present, th...
