Embodiment 1

[0010] Embodiment 1: A waterproof sealing silicone ring for LED lighting fixtures, comprising the following components and the mass percentage of each component is: 33% of silica gel, nano-TiO 2 12%, ZnO9%, epoxy resin 19%, vinyl silicone oil 12%, boron nitride 7%, graphite powder 6%, silane coupling agent 0.5%, thixotropic agent 0.5%, toughening agent 0.6%, stabilizer 0.4%.

[0011] Further, the thixotropic agent includes benzoyl peroxide.

[0012] Further, the stabilizer includes hydroquinone.

[0013] The present invention uses nano-TiO 2 and ZnO as antibacterial agents, while nano-TiO 2 ZnO and ZnO are antibacterial agents with photocatalytic activity. This antibacterial agent has a good bactericidal effect under the external light of LED light and the presence of oxygen. It uses epoxy resin and vinyl silicone oil as a heat-conducting substrate. Graphite powder, Boron nitride is used as a thermal conductivity agent, and boron nitride, nano-TiO 2 It acts as a flame ret...

Abstract

The invention relates to a waterproof seal silica gel ring for an LED illuminating lamp. The waterproof seal silica gel ring is prepared from the following components in percentage by mass: 28-38% of silica gel, 8-15% of nano TiO2, 6-12% of ZnO, 16-24% of epoxy resin, 8-15% of vinyl silicone oil, 5-10% of boron nitride, 4-10% of graphite powder, 0.3-1% of a silane coupling agent, 0.2-1% of a thixotropic agent, 0.3-1% of a flexibilizer and 0.3-1% of a stabilizer. The waterproof seal silica gel ring has high-and low-temperature resistant characteristics, a thermal conduction characteristic and a flame-retarding characteristic, and is safe in use and long in service life.

Description

technical field [0001] The invention relates to LED lighting fixtures, in particular to a waterproof sealing silicone ring for LED lighting fixtures. Background technique [0002] LED lighting fixtures refer to appliances that can transmit light, distribute and change the light distribution of LED light sources. With the further maturity of LED technology, LED will achieve more and better development in the field of design and development of living room lighting fixtures. The design of modern room lighting will be based on LED lighting design, and at the same time fully reflect the development trend of energy-saving, healthy, artistic and humanized lighting, and become the leading room lighting culture. The LED lighting fixture is provided with a silicone ring that acts as a waterproof seal for the LED lamp. The existing waterproof sealing silicone ring for LED lighting fixtures is mainly made of silica gel as the main raw material, but this waterproof sealing silicone ring...
