Abstract

The invention relates to the technical field of polishing consumables, in particular to a glass polishing pad and a preparation method thereof. Including a base pad and an abrasive adhesive attached to the surface and gap of the base pad, the abrasive adhesive includes the following raw materials in parts by weight: 15-30 parts of polyether monomer, 1-5 parts of isocyanate, 25-40 parts of abrasive , 3-7 parts of pore-forming agent, 15-30 parts of solvent. In the glass polishing pad of the present invention, abrasives are bonded on the base pad with an adhesive as a medium, so that the fibers of the base pad and between the gaps contain abrasives, and the abrasives and the base pad fall off synchronously during the polishing process of the polishing pad. The water acts at the same time to achieve a better polishing effect than the polishing liquid, and can improve the service life and efficiency of the polishing pad, reduce environmental pollution, reduce human hazards, and have a good polishing effect.

Description

technical field [0001] The invention relates to the technical field of polishing consumables, in particular to a glass polishing pad and a preparation method thereof. Background technique [0002] Rare earth polishing powder has the advantages of less dosage, fast polishing speed and high polishing efficiency, and can change the polishing quality and operating environment. Generally, rare earth glass polishing powder mainly uses cerium-rich oxide. The reason why cerium oxide is an extremely effective polishing compound is that it can simultaneously polish glass in two forms of chemical decomposition and mechanical friction. Rare earth cerium polishing powder is widely used in the polishing of cameras, camera lenses, TV picture tubes, eyeglass lenses, etc. In recent years, the field of 3C electronic products such as glass mobile phone shells, screens, integrated circuit boards, etc. has developed rapidly, and glass polishing materials have a wide range of applications. prosp...
