Abstract

The invention provides an epoxy adhesive for an LED lamp tube plug, wherein the epoxy adhesive comprises a resin component and a curing agent component with the ratio of 1:1. The resin component comprises, in parts by weight, 160-200 parts of epoxy resin, 1-50 parts of epoxy resin modified by dimeric acid, 35-50 parts of a filler and 7-12 parts of a thixotropic agent. The curing agent component comprises, in parts by weight, 180-220 parts of a mercaptan curing agent, 10-100 parts of a filler, 6-9 parts of a thixotropic agent and 5-80 parts of a polyurea rheological agent. The epoxy adhesive does not need refrigeration, does not need to be back to warm for waiting before use, can be cured at room temperature, does not need heating, and has simple and easy bonding process.

Description

Technical field [0001] The invention relates to the technical field of LED lamp tube manufacturing, in particular to an epoxy glue for LED lamp tube plugs and LED lamp tube glue. Background technique [0002] In the current fluorescent tube market, LED tubes have become mainstream products, such as T5 lamps and T8 lamps. The annual production and sales of such lamps are very huge. The structure of lighting products such as T5 lamps and T8 lamps generally includes LED strips, controllers, glass tubes and metal plugs. In the production process, after fixing the LED light strip and the controller in the glass tube, a small amount of adhesive needs to be applied to the inside of the metal plug to stick the plug to the glass tube. After the plug is attached to the glass tube, a certain bonding strength must be reached within 10 minutes to facilitate subsequent processes. [0003] Most of the existing plugging glues for bonding plugs are made of silica gel, and they are mainly additive...
