Problems solved by technology

In this method, the refractive index distribution curve of the self-focusing lens must first be known, and then it can be processed. For a lens truncated by a self-focusing fiber, there may be a variety of refractive index curve distributions, and it is impossible to test each one and then improve it.
In addition, this method is very complicated and must be treated with high-temperature molten salt, which requires high temperature control

Abstract

The invention discloses a preparation method of a repairing material for scratches on a self-focusing glass device. The preparation method comprises the steps: 1, dissolving tetrabutyl titanate in low alcohol to prepare a 1-20 percent solution; 2, dissolving organic acid in pure water to prepare a 0.1-10 percent solution B; 3, heating the solution A to 80 DEG C, gradually dropping the solution B in the solution A to obtain a solution C; 4, dissolving organosiloxane in the low alcohol to prepare a 0.5-5 percent solution D, once adding the solution D in the solution C, filling nitrogen with a pressure range of 0.1-1 MPa, reacting for 0.5-24 hours at the temperature of 80 DEG C and the pressure of 0.1-1 MPa; and 5, cooling to a room temperature, and ageing. The invention provides the preparation method of the repairing material for the scratches on the surface of a self-focusing lens, the surface of a self-focusing optical fiber and the surfaces of other glass devices with a self-focusing function.

Description

technical field [0001] The invention belongs to the field of material preparation and application, and relates to a method for preparing a self-focusing glass device scratch repair material, a scratch repair material formed based on the method, and a scratch repair method based on the scratch repair material. Background technique [0002] Self-focusing fiber is a kind of fiber whose refractive index distribution changes radially. The principle is that when light travels in the air and encounters different media, the direction of propagation will be changed due to the difference in the refractive index of the media. The refractive index of the self-focusing fiber increases gradually from the cylindrical surface to the center, so the path of light transmission inside it is sinusoidal. The self-focusing fiber is truncated according to N times of its focal length (N≧1, rounded as an integer) to form a self-focusing lens, which has the functions of focusing and imaging. The dif...
