The vitreous brick buffing wheel comprises grinding abrasive materials, binding agents and auxiliary filling materials. In the present invention, buffing powder and silicon carbide are used as the grinding abrasive materials; magnesite cement and thermoplastic phenolic resin are used as the binding agents; rare earth and the oxide thereof, stearic acid and light calcium carbonate are used as the auxiliary filling materials. The present invention has the advantages of low price, simple manufacture technology, high speed of glossiness enhancement, and long glossiness duration time, and simultaneously, low grinding temperature can not cause workpiece break.
Description
Technical field
The present invention relates to the composition of vitreous brick buffing wheel.
Background technology
The vitreous brick is meant that with clay, feldspar, quartz or clay, feldspar (porcelain stone), talcum etc. be primary raw material, is pressed into the ceramic product that base, high temperature sintering form through ball milling, mist projection granulating, height.Its Mohs' hardness and wearability all are higher than marble and general granite.According to the difference of manufacturing process etc., the vitreous brick can be divided into artificial granite brick, brindled brick and pattern permeating tile or the like again.
The high rigidity of vitreous brick and wearability, poor thermal shock resistance, crisp fritter, characteristics such as can not fix, make that the grinding and polishing processed finished products rate of vitreous brick is lower, surface gloss is inhomogeneous.Our experimental study shows that vitreous brick grinding and polishing processing is adopted with granite and processed similar equipment and processing technology, and stone material grinding and buffing wheel and processing technology, and be not suitable for processing vitreous brick.
Suitable vitreous brick grinding and polishing processing technology should be to add man-hour at abrasive grinding wheel at corase grind, can excise a large amount of workpiece materials, but be unlikely to produce deep torn grain.Add man-hour at half correct grinding, the processing pit that abrasive grinding wheel should make former procedures produce shoals, and produces enough plasticity grooves, improves the preceding crudy of fine finishining; The fine finishining abrasive grinding wheel should make polish the surface and tiny plasticity groove be main, the raising surface smoothness, the surface microstructure glassy surface is exposed.
Buffing wheel must make crystal gloss improve, and reduces surperficial light scattering degree by the roughness that reduces the surface, makes the surface present certain gloss; In the process, must prevent that buffing wheel from stopping up and cooling is not enough, cause possible grinding temperature too high, produce crack due to thermal stress and workpiece fragmentation.
The polishing efficiency of buffing wheel and polishing glossiness have directly influenced the quality of vitreous brick product; The cost of buffing wheel has been determined the machining tool cost of grinding and polishing operation to a great extent.The buffing wheel composition of open report is exemplified below:
Chinese patent publication number CN1260334A has proposed a kind of vitreous brick grinding and polishing prescription; it is characterized in that adopting vitrified bond; behind the batch mixing pulping, inject abrasive tool moulding; using the high temperature sintering finished product at last. it is the processing of stone grinding tool of abrasive particle with white fused alumina micro mist and Cr that Japan Patent JP2002-361562 discloses a kind of; also having adopted sintering process. the sintering process of these grinding tools makes grinding tool manufacturing process complexity; manufacturing cost improves. and Chinese patent publication number CN1016892A has proposed a kind of stone grinding or composition for use in polishing and manufacture method thereof; mainly use by abrasive material and bond and chemical grinding or polishing oxide lead oxide in the polishing part; oxalic acid is formed. be applicable to that mainly main component is the polishing of the materials such as marble of calcium carbonate. and Chinese patent publication number CN1275601A proposes a kind of grinding tool of crystallized glass; relate generally to the manufacturing process of corase grind grinding tool; to improve grinding productivity ratio is main target. Chinese patent publication number CN1387976A has proposed a kind of poultry hair that contains; the stone material grinding tool of graphitic lubricant and rare earth metal and oxide, the polishing stone material is obtained higher glossiness.
Summary of the invention
The objective of the invention is the polishing process characteristics at brokenization brick, a kind of composition of vitreous brick buffing wheel is provided, this emery wheel has high polishing efficiency and polishing glossiness.
The invention provides a kind of composition that is used for vitreous brick buffing wheel, it contains grinding abrasive material, binding agent and auxiliary packing; Adopt polishing powder and carborundum as the grinding abrasive material, magnesia cement and novolac resin are as binding agent, and rare earth and oxide thereof, stearic acid, precipitated calcium carbonate are as auxiliary packing.It is as follows that it forms the percentage by weight ratio:
Component ratio (percentage by weight %)
MgO 32.4-33.8
MgCl
2 40-46
Phenolic resins 1.5-5
SiC 7-12
Al
2O
3 5-9
Precipitated calcium carbonate 1.3-4
Stearic acid 0.3-0.8
Rare earth and oxide 0.5-2.0 thereof
The present invention adopts magnesia cement as binding agent, because our experimental study shows that its technology is simple, cheap and have certain intensity simultaneously, can reach good polishing effect.
The present invention adopts the bond strength of novolac resin raising magnesia cement, increases the elasticity of grinding tool simultaneously, reduces polish temperature and brings the possibility on burn vitreous brick surface thus.
The present invention is also adding precipitated calcium carbonate and stearic acid aspect raising emery wheel mechanical performance and the self-sharpening energy.
The present invention adopts SiC and Al
2O
3As polish abrasive.The a small amount of polishing scratch that utilizes the good cutting power of SiC further correct grinding to be stayed is removed; Simultaneously, Al
2O
3The micro-cutting effect of abrasive material; after making that polishing is processed; vitreous brick surface is made up of pit (pore), flat surfaces and trickle plasticity groove etc.; the crystal glassy surface exposes; add the specific physical chemical action that interpolation rare earth and oxide cmp emery wheel thereof bring; make grinding skin smooth, glossiness improves.Our experimental study shows, does not generate any new structure of matter or polished film, SiC, Al at polished surface
2O
3With the mechanical micro-cutting of rare earth and oxide cmp thereof and physics chemical action be the main cause that vitreous brick surface obtains glossiness.
The manufacture method of emery wheel of the present invention is as follows: at first with abrasive material SiC, Al
2O
3, rare earth and oxide, precipitated calcium carbonate, stearic acid, phenolic resins and magnesia (MgO) stir together, adds MgCl again
2, the material that will stir again at last is poured in the plastics mould, and the demoulding after 3-4 hour can be used in maintenance 12-15 days.The removal of contamination that must sieve such as abrasive material and MgO.MgCl
2Answer removal of contamination after the dissolving, and before stirring, stir well even.
MgO/MgCl
2, ratio should suitably adjust according to the spice situation, guarantee to stir evenly moulding of material, but the proportion of composing scope can not exceed above-mentioned scope, to guarantee enough grinding tool intensity and performance.Simultaneously, throwing preceding vitreous brick glossiness should be more than 20.
The invention has the advantages that: it is fast that low price, manufacturing process are simply, glossiness improves speed, the gloss longer duration, and grinding temperature is low simultaneously can not cause workpiece to break.
