Embodiment Construction

[0019] Below in conjunction with specific embodiment, this case is described in further detail.

[0020] The invention relates to an artificial stone grinding disc, which is prepared by uniformly mixing diamond particles and a carcass binder and forming by hot pressing. The carcass binder is mainly made of the following components in weight ratio: melamine formaldehyde resin 40-60%, filler 25-40%, silicon carbide 0-15%, white corundum 0-5%.

[0021] Diamond is the main abrasive, which has the greatest grinding effect, and the weight is preferably 5-15%, which can meet the grinding requirements and take into account that the production cost will not be too high. The particle size of diamond particles is preferably 50-2000 mesh. At this time, it is desirable that the weight ratio of the diamond particles is 10%, and the particle size of the diamond particles can also be selected according to actual requirements. The shape of silicon carbide is irregular, relatively brittle, an...

Abstract

The invention discloses a method for preparing an artificial stone grinding sheet. The method comprises the steps that (1) melamino-formaldehyde resin and filler are dosed according to the weight ratio of (40%-60%):(25%-40%); (2) carborundum and white corundum are added according to the weight ratio of (0-15%):(0-5%), mixing is carried out, and a matrix binding agent is prepared; (3) then diamondparticles are added into the matrix binding agent according to the weight ratio of 5%-15%, full stirring is carried out for more than 10 hours, and evenly mixed powder is prepared; and (4) the evenlymixed powder is put in a steel mold, leveling is carried out, nylon hook cloth is put in the steel mold, finally a pressing head is put in, the steel mold and the pressing head are put on an oil pressto be heated, sinter molding is carried out. The use sharpness of the grinding sheet special for artificial stone polishing is greatly improved, the service life of the grinding sheet is greatly prolonged, and the sharpness and the service life are more than two times those of a traditional grinding sheet, and the traditional grinding sheet can be replaced well; and the beneficial effects that dyeing and burning are avoided, the polishing effect is good, the yield is high, and the machining efficiency is remarkably improved are achieved.

Description

[0001] This application is for an application whose application number is "201610103079.X" and the application date is 2016.2.25 and the subject is "a Artificial stone grinding disc and its preparation method” filed a divisional application. technical field [0002] The invention relates to the field of artificial stone abrasive tools for grinding and polishing, in particular to a preparation method of a special grinding plate for artificial stone. Background technique [0003] Artificial stone is a kind of synthetic decorative material, which is a kind of polymer material polymer, and its main components are resin, aluminum powder, pigment and curing agent, so it is also generally called resin board artificial stone. At present, there are no grinding discs dedicated to artificial stone grinding and polishing on the market, and they are all related abrasive tools for grinding and polishing of granite natural stone. In the actual use process, people found that it has such ...
