[0030] The present invention firstly provides a method for preparing a self-focusing glass device scratch repair material, the method comprising the following steps:
[0031] 1) Dissolve tetrabutyl titanate in lower alcohol, and prepare a solution with a mass percentage of 1-20%, and mark it as A solution;
[0032] 2) Dissolve the organic acid in pure water, and prepare a solution with a mass percentage of 0.1-10%, and mark it as B solution;
[0033] 3) Put the A solution prepared in step 1) into the autoclave and heat it to 80°C; gradually add the B solution prepared in step 2) into the A solution dropwise, and react to obtain the C solution;
[0034] 4) Dissolve organosiloxane in lower alcohol, and prepare a D solution with a mass percentage of 0.5-5%, and add the D solution to the C solution obtained in step 3) at one time; fill with nitrogen , the pressure range is 0.1-1MPa; keep the reaction at this temperature (80°C) and pressure for 0.5-24h;
[0035] 5) Gradually cool...

[0046] Dissolve tetrabutyl titanate in ethanol to prepare a solution with a mass percentage of 1%, and mark it as A; dissolve malic acid in pure water to prepare a solution with a mass percentage of 0.1%, and mark it as B; Put the A solution in a high-pressure reactor and heat it to 80°C; gradually add B into A dropwise to obtain C, and the dropping time is 0.5h; dissolve methyltriethoxysilane in ethanol to prepare a mass percentage It is a 0.5% solution, which is added to C at one time; then filled with nitrogen, and the pressure range is 0.1MPa; keep the temperature and pressure for 0.5h; gradually cool to room temperature, and age for 48h to obtain the scratch repair material. The scratch repairing material is colorless and transparent, has a pH of 5-6, and a viscosity of 3-5 mPa·s. The material can form a transparent protective layer on the surface of a glass device, meeting the requirements for protecting the device.
