Problems solved by technology

[0003] However, since the polishing agent smoothes the surface of the material by scraping, the inevitable problem is that as the surface flatness of the polished object increases, it is scratched by the abrasive particles in the polishing agent. The chances are also increasing
[0004] In addition, since the existing polishing machines all adopt the motion mode of circular rotation, the abrasive particles in the polishing agent tend to be displaced to the edge of the grinding disc of the polishing machine due to the effect of centrifugal force, which will bring two problems. The polishing effect at the central position decreases, and the second is that the surface of the object at the edge of the disc is more likely to be scratched by dense abrasive particles

[0020]

[0021] As grinding progresses, tetraethyl orthosilicate gradually decomposes to form SiO 2 , SiO 2 with Fe 3 o 4 And the microstructure on the surface of the carbon fiber is a crystallization nucleus, forming a large number of microcrystals, thereby forming more refined abrasive particles, so as to effectively prevent the possibility of causing larger scratches on the previously ground flat surface, and because the microcrystals are finer, Therefore, the surface finish can be further improved to achieve the effect of killing two birds with one stone.

Abstract

The invention provides a glass polishing agent which is characterized by comprising the following components by weight: 60-80 parts of water; 2-6 parts of isopropyl alcohol; 10-20 parts of silica micropowder; 8-15 parts of Fe3O4 powder with the particle diameter range of 0.3-1.2 microns; 1-3 parts of a frothing agent; 0.01-0.03 part of carbon black; 1-3 parts of short carbon fiber with the length range of 0.2-1.5 mm. As Fe3O4 is taken as a grinding agent, and Fe3O4 has magnetic property, during a grinding process, the grinding agent is prevented from dispersing under the action of centrifugation due to own magnetism and can be distributed more evenly on the surface of an object to-be-polished under the action of pushing of an external force.

Description

technical field [0001] The invention relates to a glass polishing agent, which belongs to the field of chemical industry. Background technique [0002] Polishing agent is a common agent to improve the flatness of glass surface. The basic principle is to reduce the roughness of the glass surface through repeated scraping of fine polishing particles, so as to achieve a smooth and smooth visual effect. Existing polishing agents mostly use tiny abrasive particles and various suspending agents for polishing operations. [0003] However, since the polishing agent smoothes the surface of the material by scraping, the inevitable problem is that as the surface flatness of the polished object increases, it is scratched by the abrasive particles in the polishing agent. The probability is also increasing. [0004] In addition, since the existing polishing machines all adopt the motion mode of circular rotation, the abrasive particles in the polishing agent tend to be displaced to the...
