To be different from the existing polishing disc, the rare earth polishing disc mainly comprises rare earth polishing powder, resin, magnesium sulfate or white sugar, curing agent and accelerating agent, wherein the rare earth polishing powder comprises the following compositions in percentage by weight: more than or equal to 60 percent but less than or equal to 99.99 percent of cerium oxide, and more than or equal to 0.01 percent but less than or equal to 40 percent of lanthanum oxide, the content of the rare earth polishing powder can achieve 65 percent, the relative particles of the rare earth polishing powder is small, the brightness of a polished object can be greatly improved compared with the original polishing disc, and the polishing time of the surface of a product can be shortened to be about 0.6 second, so that the working efficiency is improved, the wear resistance property is greatly improved, 1,000-1,200 NO.40 crystal balls can be polished by the original polishing disc with the same size, while the rare earth polishing disc can polish 4,000 NO.40 crystal balls.
Description
Technical field
The present invention relates to a kind of rare earth polishing disk.
Background technology
Polishing disk is mainly in various glass surfaces and side; Water bores; Use in the polishing such as Crystal ornaments; Also be that the high-grade glass handicraft is processed requisite polishing abrasive tool, the at present main practice is polishing disk to be fixed on the rotating disk of polishing machine crystal, Glass Craft etc. are polished processing, can be used for monolithic and become dish process and streamline on processing in batch.Polishing disk in the past is main body with the rare earth cerium oxide mainly, makees binding agent with the fiber twine, adds promoter; Grinding aid, the PH stabilizing agent is made, and this polishing disk often exists stock removal rate low; The not high shortcoming of surface brightness is polished a product needed long period, inefficiency; And wearability is not high, and service life is shorter, needs often to change the waste ample resources.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes prior art, and the rare earth polishing disk that a kind of stock removal rate is high, wearability is good, surface brightness is high is provided.
The technical scheme that the present invention adopted is: the rare earth polishing disk that the present invention relates to is to be made by following component:
A component: polishing powder from rare earth;
B component: resin;
C component: magnesium sulfate or white sugar;
D component: curing agent and promoter;
Wherein the composition of polishing powder from rare earth comprises by mass percentage: 60%≤cerium oxide≤99.99%, 0.01%≤lanthana≤40%.
Polishing disk of the present invention is different according to its manufacture craft; Can be divided into following dual mode; The ratio of the two corresponding each component is also different, and wherein cast-type rare earth polishing disk is that each component is mixed, and is poured in the mould; Be finished product after the moulding, said according to the mass fraction each component ratio of cast-type rare earth polishing disk is: A component 50～60; B component 10～20; C component 17～27; D component 0.05～0.1.
The polishing disk of another kind of production method is a compacting formula rare earth polishing disk, mixes through each component with the rare earth polishing disk, and in certain process conditions pressed moulding, said according to the mass fraction each component ratio of compacting formula rare earth polishing disk is: A component 55～65; B component 7～13; C component 25～35; D component 0.05～0.15.
In such scheme; Said resin is meant the wherein a kind of of phenolic resins, epoxy resin, unsaturated polyester resin or the like; And the D component: curing agent and promoter are to adopt common curing agent and the promoter in market; Also can be identical with promoter with the curing agent that adds in the existing polishing disk manufacture craft, be meant unsaturated polyester resin like common curing agent.
The invention has the beneficial effects as follows: rare earth polishing disk of the present invention adopts new prescription and unique processes to be made, and with respect to polishing disk in the past, following advantage is arranged:
(1) wearability is good: in the past can only polish 1000 ~ 1200 of the crystal balls of 40# of onesize polishing disk, the present invention can reach the level of 4000 of polishings.
Pressure is little when (2) polishing: the present invention adds curing agent, can make polishing disk sturdy and durable, thereby need not to press polishing disk, breaks to prevent polishing disk.
(3) stock removal rate is good: make the polishing time of product surface shorten about 0.6 second, improved operating efficiency.
(4) brightness is high: in preferred version of the present invention, be that the polishing powder from rare earth that main material is processed is a primary raw material to contain rare earth, particle is little, can improve the brightness that needs the polishing object greatly with respect to polishing disk in the past.
