Problems solved by technology

[0002] Grinding and polishing are one of the commonly used processing methods for metal materials. At present, abrasive materials similar to grinding wheels are most used, but rigid grinding wheels are only suitable for processing flat metal workpieces. There are many For parts with special-shaped and complex surfaces, when the surface finish needs to be improved, grinding wheel grinding is powerless

Abstract

The invention discloses a resin matrix composite for flexible grinding and polishing, belongs to the technical field of composites, and relates to a preparation method of the resin matrix composite for flexible grinding and polishing. The preparation method of the resin matrix composite comprises the following steps of: mixing cement, quartz sand of 100 to 200 meshes and alumina powder of 100 to 200 meshes according to a certain weight percentage ratio, adding water and a polycarboxylic acid water reducer, stirring in a mortar mixer for 3 to 5 minutes, coating slurry on the surface of resin foam to allow the slurry to enter the resin foam, and curing in a standard curing box at the temperature of between 19 and 21 DEG C and the humidity of more than 90 percent for 3 to 7 days, wherein the composite can meet grinding and polishing requirements. The method is simple in process, low in production cost, and high in application value in grinding and polishing the surface of a special-shaped complex workpiece and improving the surface finish of the special-shaped complex workpiece.

Description

technical field [0001] The invention specifically relates to a method for preparing a resin-based composite material for flexible grinding and polishing, which is used for grinding and polishing treatment of special-shaped complex surfaces. Background technique [0002] Grinding and polishing are one of the commonly used processing methods for metal materials. At present, abrasive materials similar to grinding wheels are most used, but rigid grinding wheels are only suitable for processing flat metal workpieces. There are many When it is necessary to improve the surface finish of parts with special-shaped and complex surfaces, grinding wheel grinding is powerless. The abrasive tool material capable of flexible grinding and polishing obtained by the invention can solve such problems. Contents of the invention [0003] The invention provides a method for preparing a resin-based composite material for flexible grinding and polishing. The preparation process of the resin-bas...
