Embodiment 1

[0048] (1) Weigh 400 grams of nano-silica methanol solution MA-ST-M from Nissan Corporation of Japan, 100 grams of nano-silica isopropanol solution IPA-ST-L from Nissan Corporation of Japan, and mix two kinds of nanometer silica Silicon dioxide alcohol solution, slowly add the second nanometer silicon dioxide alcohol solution to the first nanometer silicon dioxide alcohol solution, each addition is 20 grams and stir for 2 minutes, after all mixing, disperse with ultrasonic oscillator for 15 minutes minute;

[0049] (2) Weigh 46.7 grams of polyester modified silicone resin SM1062-40 from Jiangsu Sanki Chemical Co., Ltd., and 8.5 grams of blended modified rubber T8010 of EPDM rubber and methyl vinyl silicone rubber from Japan Synthetic Rubber Company. gram, under the condition of 100℃ water bath, use homogeneous dispersant to disperse for 15 minutes. Add the prepared modified silicone binder containing silicon-oxygen bonds to the siloxane alcohol solution obtained in step (1) a...

Embodiment 2

[0057] The operation is basically the same as in Example 1, except that 450 grams of the nano-silica methanol solution MA-ST of Japan Nissan Co., Ltd. is weighed, the average particle diameter of the nano-silica is 10-15 nanometers, and the solid content of the silica 30-31%, 150 grams of nano-silica isopropanol solution IPA-ST from Nissan Japan, the average particle size of nano-silica is 10-15 nanometers, and the solid content of silica is 30-31%. Compared with Example 1, the nano-silica particle size of Example 2 is smaller, and the solid content of silica in the silica sol is small. The polishing film made of it is used to polish the pre-grinded fiber end ferrule end face, and the polishing parameters are as shown in Table 1 above. It shows that under a 200x microscope, the end face of the optical fiber head before polishing is as image 3 As shown in (a), the end face of the optical fiber head after polishing is as follows image 3 As shown in (b), it can be seen from th...

Embodiment 3

[0059] The operation is basically the same as in Example 1, except that 1,200 grams of the nano-silica methanol solution MA-ST-M of the Nissan Company of Japan is taken, and 1,200 grams of the nano-silica isopropanol solution IPA-ST-L of the Nissan Company of Japan are taken. 300 grams, compared with embodiment 1, example 3 has improved the ratio of nano-silica, and the optical fiber head ferrule end face of pre-grinding is polished with the polishing film that it is made, and polishing parameter is as shown in above table 1, under 200 times of microscopes , the end face of the fiber optic head before polishing is as Figure 4 As shown in (a), the end face of the optical fiber head after polishing is as follows Figure 4 As shown in (b), there are still a lot of scratches on the surface, and the polishing efficiency is low. This is because the proportion of the modified silicone binder in the abrasive coating is reduced. The binder cannot effectively hold the abrasive grains, ...

Abstract

The invention discloses a nano-silica polishing film adopting a modified organosilicone binder and a preparation process of the nano-silica polishing film. The preparation process comprises steps as follows: (1), nano-silica alcoholic solutions with two grain sizes are mixed, and the grain size ranges from 10 nanometers to 500 nanometers; (2), the modified organosilicone binder containing silicon oxygen bonds is prepared, added to the nano-silica alcoholic solutions obtained from the step (1) and stirred, a curing agent is added, and the mixture is subjected to ultrasonic oscillation dispersion for 30 minutes; (3), a film substrate surface is subjected to surface modification treatment; (4), the film surface obtained from the step (3) is coated with a coating solution obtained from the step (2); (5), the coated film obtained from the step (4) is cured for one hour in a vacuum oven at the temperature of 70 DEG C, and the nano-silica polishing film is obtained. The nano-silica polishing film has the characteristics of uniform distribution of grains, high polishing efficiency and good workpiece polishing quality.

Description

technical field [0001] The invention belongs to the field of precision grinding and polishing, and relates to a nano-silicon dioxide polishing film, in particular to a nano-silicon dioxide polishing film using a modified organic silicon binder and a manufacturing process thereof. Background technique [0002] In daily life, optical fibers are used for long-distance information transmission because the loss of light in optical fibers is much lower than that of electricity in wires. With the advent of 4G and 5G networks, the optical fiber industry has once again ushered in a good opportunity for development. [0003] As an important component of the optical fiber, the optical fiber head directly affects the quality of optical fiber signal transmission. At present, the main process of processing the end face of the 2.5mm jumper fiber optic head is D30 glue removal for 30 seconds, D9 grinding for 35 seconds, D3 grinding for 35 seconds, D1 grinding for 35 seconds, and ADS polish...
