Abstract

The invention relates to an adhesive for an LED lamp tube plate, which comprises the following components in parts by weight: 15-45 parts of halogen-free epoxy resin which is low-hygroscopicity epoxy resin; 15-45 parts of nitrile rubber; 0.1-8 parts of a curing agent; 5-60 parts of a phosphorus-containing composite flame retardant; and 0.1-5 parts of an auxiliary agent. The halogen-free epoxy resin with low hygroscopicity is adopted, conventional straight-chain resin is omitted, the moisture absorption condition is avoided, on one hand, the copper-clad plate does not need to be curled due to the moisture absorption condition, the production efficiency of the follow-up lamp bead pasting process is guaranteed, on the other hand, deformation of the LED lamp tube plate caused by curling of the copper-clad plate is avoided, the lamp tube plate material is not prone to curl in the using process, adverse effects on use of the LED lamp tube plate are avoided, and the service life of the LED lamp tube plate is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of LED lamp tube boards, and in particular relates to an adhesive used for LED lamp tube boards. Background technique

[0002] At present, single-sided copper-clad laminates are mostly used for LED lamp tube boards. When manufacturing single-sided copper-clad laminates, straight-chain bisphenol A resin is used and cured with imidazole. As a result, both the PI film and the adhesive are easier to absorb moisture. On the one hand, during the production and storage of ordinary single-sided copper-clad laminates, the polyimide film and epoxy glue will absorb moisture, causing the copper-clad laminates to curl and affect the subsequent lamp bead paste process, especially after reflow soldering. The curling situation is more serious, which greatly reduces the production efficiency of the lamp bead sticking process. On the other hand, it causes the LED lamp tube board to curl during use, which affects the use. Co...
