Problems solved by technology

This kind of abrasive product has a disadvantage: the abrasive in the coating is mixed with the resin adhesive, and only the abrasive on the surface can play a grinding role. When the abrasive on the surface is blunted, the cutting force of the product will be greatly reduced, resulting in a decrease in the grinding life. It also causes waste of abrasives. Even if the abrasive content is greatly increased, it will not achieve good results. Such products often cannot provide long-lasting and stable high cutting force
This abrasive paper can be used for grinding and polishing many workpieces, but when it is applied to optical fiber connectors, the cutting force is not uniform enough and the cutting effect is not good

Embodiment 1

[0036] (1) Preparation of nano-silica sol: adding 10ml mass concentration to 500ml alcohol-soluble silica (Nissan Chemical, IP-ST) is 10% hydrochloric acid, 20ml surface modifier KH-570, 6g water, slowly stirring, Heating to 70°C, reacting for 8 hours and then evaporating and concentrating to about 200ml to obtain nano-silica sol. The particle size in the nano-silica sol was detected to be about 90nm.

[0037] (2) Pretreatment of the base material: Coating 909 (Nanya epoxy resin) with 1% of the curing agent N3390 (Bayer, Germany) on the PET tape base to form a pre-coating layer, cured at 60°C for 24 hours for later use ;

[0038] (3) After mixing the nano-silica sol obtained in step (1), the second soluble resin and the soluble curing agent, configure the abrasive coating solution according to the consumption in Table 1, wherein the weight content of silicon dioxide after drying is 82%;

Abstract

The invention discloses a nanometer silicon dioxide thin film base polished section and a preparation method of the nanometer silicon dioxide thin film base polished section. The preparation method includes the following steps that (1) nanometer silicone sol is prepared; (2) a precoating is coated on a PET tape base and a processed base material is obtained; (3) the nanometer silicone sol, soluble resin, and a soluble curing agent are mixed and then abrasive coating liquid is obtained; (4) the abrasive coating liquid is evenly coated on the base material processed in the step (2), a semi-finished product is obtained and is solidified under 80 DEG C to 100 DEG C for 40 hours to 60 hours, and the nanometer silicon dioxide thin film base polished section is obtained. The nanometer silicon dioxide thin film base polished section is even in cutting force, and good in polishing effect when the polished section is applied to an optical fiber connector.

Description

technical field [0001] The invention belongs to the field of precision polishing of optical fiber connectors, and in particular relates to a nano silicon dioxide film-based polishing sheet and a preparation method thereof. Background technique [0002] Traditional coated abrasive products are obtained by directly mixing abrasives and adhesives, coating them on the surface of the substrate, and curing them. This kind of abrasive product has a disadvantage: the abrasive in the coating is mixed with the resin adhesive, and only the abrasive on the surface can play a grinding role. When the abrasive on the surface is blunted, the cutting force of the product will be greatly reduced, resulting in a decrease in the grinding life. It also causes waste of abrasives. Even if the abrasive content is greatly increased, it will not achieve good results. Such products often cannot provide long-lasting and stable high cutting force. [0003] The promotion of fiber-to-the-home has greatly...
