Problems solved by technology

And the elastic modulus is large, the creep is small, and the bonding force is strong, which can reduce the influence of the stress on the optical fiber ring when the temperature changes.
However, the prior art still cannot meet the above-mentioned performance requirements.

Abstract

The invention discloses adhesive glue for an optical fiber ring and a preparation method of the adhesive glue. The adhesive glue is characterized by being prepared by mixing the following components in parts by mass: 35-60 parts of flexible amino resin, 35-60 parts of flexible epoxy group acrylic resin and 1-5 parts of a coupling agent modified heat-conduction inorganic nanofiller. The viscosity of the adhesive glue is 5000cps-5500cps at 25 DEG C, and the glass-transition temperature is (-60)-(-40) DEG C; the elasticity modulus is 50MPa-60MPa at 23 DEG C, the cure shrinkage rate is 0.1%-0.5%,and the heat conductivity is 0.8W(m.K)-1.2W / (m.K); and the adhesive glue can be completely cured within 5-8 hours at 50-90 DEG C. The adhesive glue for the optical fiber ring is high in viscosity, elasticity modulus and heat conductivity, low in glass-transition temperature and cure shrinkage rate, adjustable in curing period and applicable to the adhesion of optical devices.

Description

technical field [0001] The invention belongs to adhesive glue for optics and its devices and its preparation, in particular to an adhesive glue for optical fiber ring and its preparation method.
