Abstract

Disclosed is an abrasive for use in moisture blasting. The disclosed abrasive is formed from spherical polymer particles derived from a monomer mixture containing 0.1-20 parts by weight of a (meth)acrylate monomer containing either an ether group and a hydroxyl group, or an ester group and a hydroxyl group, and 100 parts by weight of a vinyl monomer other than the (meth)acrylate monomer. When polymerisation to the surface of the spherical polymer particles takes place, the attached number of emulsions and / or microparticles which are secondarily generated is not greater than 9 (here the number of attached substances is the average value for five visual fields of an arbitrary region of 6[mu]m * 5[mu]m of the polymer particles).

Description

Technical field

[0001] The invention relates to an abrasive used for wet sandblasting and a manufacturing method thereof. More specifically, the present invention relates to an abrasive for wet sandblasting and a method for manufacturing the same, which can make less particles (abrasive) float in wet sandblasting. Background technique

[0002] A method for removing excessive burrs and paint adhering to the article by spraying abrasives on the article is known. This method is generally called sandblasting. This kind of sandblasting is used to remove burrs generated in, for example, resin molded objects, die-cast products, semiconductor molds, and automobile parts, and to peel off paint on automobiles and airplanes.

[0003] In sandblasting, various materials have been used as abrasives for a long period of time. For example, known inorganic abrasives such as silicon carbide, alumina, silica, ceramics and diamond powder. However, during grinding, these inorganic abrasives may com...
