Abstract

The invention discloses UV powder mixed silica gel and a preparation method and application thereof. The UV powder mixed silica gel comprises 30-50 parts of UV resin serving as a main body, 25-40 parts of silicon-modified photocuring monomer, 25-40 parts of photocuring monomer and 1-8 parts of photoinitiator. The UV powder mixed silica gel can be resistant to the high temperature of 280 degrees without yellowing, the high refractive index is achieved, furthermore, quite good toughness and air-tightness are achieved, and the problem that due to raising of the refractive index of traditional powder mixed silica gel, an adhesive layer is hardened, so that chalking occurs easily in the using process is effectively avoided; energy consumption is greatly lowered, the curing time is only 1 / 1800 that of the traditional powder mixed silica gel, the defects that the traditional powder mixed silica gel is high in energy consumption, long in curing time and the like are effectively overcome, and productivity is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of polymer materials, in particular to a UV powder mixing glue and its preparation method and application. Background technique

[0002] LED packaging glue is a kind of glue that covers the LED lamp bead. Its function is to protect the LED lamp bead. At present, the powder mixing glue for LED lamp bead packaging is basically two-component silica gel or two-component epoxy glue. Their curing conditions are generally baked in a high-power electric oven at 150°C for 5 hours, which consumes a lot of energy. At the same time, each batch of lamp beads needs to be baked for about 5 hours, and its efficiency is very low. In addition, the refractive index of the traditional powder-mixed silica gel is relatively low, and the increase of the refractive index usually causes the hardening of the adhesive layer, which makes it easy to pulverize during use.

[0003] UV glue is mainly composed of base resin, active monomer...
