Abstract

The invention discloses an LED light strip material with excellent heat resistance and a preparation method thereof. The LED light strip material with excellent heat resistance is prepared from the following ingredients: 35-45 parts of PTT, 20-30 parts of epoxy resin, 15-25 parts of a plasticizer, 12-18 parts of organophosphorus ester, 0.3-0.8 part of a lubricant, 20-28 parts of calcium carbonate,10-16 parts of polyether amine, 0.5-2 parts of maleic anhydride, 3-8 parts of polyethylene glycol, 0.5-1.5 parts of azodiisobutyronitrile, 18-25 parts of TPU and 0.8-1.8 parts of a light absorber. The LED light strip material has the characteristics of high strength and aging resistance.

Description

technical field [0001] The invention relates to the field of lamp materials, in particular to an LED lamp strip material with good heat resistance and a preparation method thereof. Background technique [0002] The light strip refers to the assembly of LEDs on a strip-shaped FPC (flexible circuit board) or PCB hard board, which is named for its product shape like a strip. Because of its long service life (generally, the normal life span is 80,000 to 100,000 hours) and environmental protection, it has gradually emerged in various decoration industries. But at present, the LED light strip mainly has the disadvantage of yellowing after long-term use. Contents of the invention [0003] The object of the present invention is to provide a LED light strip material with good heat resistance and a preparation method. The invention has the characteristics of high strength and aging resistance. [0004] The present invention is achieved like this. A LED light strip material with ...
