The invention relates to a superfine
abrasive biomacromolecule flexible
polishing film and a preparing method of the
polishing film and belongs to the field of combination between biomacromolecule material and super-precision
machining. The
polishing film is characterized in that a substrate of the polishing film is made of degradable biomacromolecule material, the mechanical performance of the polishing film is enhanced through selected filling agents, water carrying agents, pore forming agents and other
drying control chemical additives, and superfine abrasives can be evenly dispersed and effectively held in the polishing film with a
coupling agent
surface chemical modification method. Compared with a traditional chemical and mechanical polishing mode, the problems that free abrasives are seriously wasted, and the environment is polluted by a corrosive polishing solution are avoided. Compared with a commercial polishing film product, the biomacromolecule substrate has certain flexibility,
abrasive particles can be soaked in the biomacromolecule substrate, scratches and mechanical damage are avoided, and super-precision undamaged
machining can be achieved. The degradable superfine
abrasive biomacromolecule flexible polishing film has the advantages of being simple in preparing technology, good in polishing effect, high in
machining efficiency, capable of making a workpiece convenient to wash,
environmentally friendly and the like.
