Abstract

The invention discloses an ultraviolet (UV) light LED (light emitting diode) lamp bead packaging glue and a preparation method thereof. The UV light LED lamp bead packaging glue comprises the following components of vinyl-terminated organic polysiloxane, liquid vinyl MQ silicon resin, linear methyl hydrogen polysiloxane, a platinum complex catalyst, an inhibitor and a tackifier. The ultraviolet LED lamp bead packaging glue has the advantages that the formula is reasonable, the bond energy of silicon oxygen bond of organosilicone main chain is high, the breaking is avoided under the condition of irradiation by high-energy UV light, and the sticking effect is good; the organosilicone can maintain higher transparency rate in the wider wavelength range, the high and low temperature-resistant and anti-aging properties are realized, the transparency is high, the forming property is good, the sticking property is good, the curing condition is mild, and the comprehensive property is better; the ultraviolet light LED lamp bead packaging glue is quickly prepared by the preparation method, the technological steps are simple and concise, the implementing is easy, and the productivity is high.

Description

technical field [0001] The invention relates to the technical field of glue for packaging LED lamp beads, in particular to a glue for packaging ultraviolet light LED lamp beads and a preparation method thereof. Background technique [0002] Ultraviolet light source (UV) has fluorescence effect, biological effect, photochemical effect and photoelectric effect, and is widely used in the fields of industry, agriculture, national defense and medical treatment. While traditional UV lamps have the disadvantages of short service life, heavy metals such as mercury, and long response time, LED UV light sources have the advantages of long service life, fast response time, low heat, energy saving and environmental protection. With the requirements of energy conservation and environmental protection in the 12th Five-Year Plan of the country and the progress of science and technology, LED UV chips have gradually matured, so it is imminent to develop a glue for LED UV light source packagi...
