Abstract
By using (wt%) 5-20% of Al2O3, 5-25% of SnO2, 25-45% of Cr2O3, 15-35% of phenol formaldehyde resin and 10-15% of epoxy resin as raw material said invention adopts the main steps of uniformly mixing raw materials according to its formula, placing them into a preheated mould, pressing for 3-15 min. at 140-190 deg.C and 4-8 MPa and hardening to obtain the invented grinding tool for polishing granite. Said product possesses good grinding performance, stable quality, strong adaptability, and the surface glossiness of the granite polished by said product is stable and up to above 85 deg. and its product cost is low.
Description
The polishing grinding that the present invention relates to the building decoration stone material is handled, and specifically is meant granite polishing apparatus and manufacture method thereof.
Granite is very big, a kind of natural ornamental stone of having many uses of consumption in the construction material.The height of granite glossiness is directly connected to the height of stone material quality.Polishing abrasive tool is last a kind of grinding tool that facing granite grinding-polishing uses, and also is the crucial grinding tool of granite polishing.The quality of polishing abrasive tool is directly connected to the height of granite stone polishing glossiness.For this reason, the surface of granite polishing is the problem that people pay close attention to always.Granite polishing apparatus mainly is made up of polish abrasive, resinoid bond and filler etc. both at home and abroad, and the product overwhelming majority adopts pouring forming technology.Because raw material sources, prescription are different with manufacturing condition, the quality and the performance of the polishing grindstone of being produced also are not quite similar.Mainly be according to its practical effect to the quality evaluation of polishing various granite polishing grindstones at present.Therefore many engineers and scientific worker are all the time in the final glossiness of considering how to improve as early as possible surface of granite.
In recent years, constantly release new polishing abrasive tool both at home and abroad, for example: though Japanese butterfly board polishing abrasive tool people generally believe that result of use is better, not only price is expensive for it, and service life is short.Domestic research to polishing abrasive tool also has many reports and constantly has new grinding tool to release, but quality is generally stable not as imported product.
The objective of the invention is to overcome the deficiencies in the prior art part, providing a kind of can stablize polished granitic surface gloss to reach more than 85 °, price long relatively granite polishing apparatus in lower and service life, and a kind of manufacture method of granite polishing apparatus is provided.
The objective of the invention is to be achieved through the following technical solutions:

Step 2: precompressed
The raw material that mixes pack into cleaning, scribble and take off grinding agent and in the mould of preheating, the pressure head of moulding press is slowly depressed, temperature remains in 120～140 ℃ of scopes when touching abrasive material, squeeze time 1～6 minute;
Step 3: compacting
Under the pressure of 140～190 ℃ temperature, 4～8MPa, suppressed 3～15 minutes after the precompressed;
Step 4: post processing
Carry out the demoulding after finishing compacting, and carry out cure process, asked during cure process 7～15 hours hardening furnace furnace temperature＜150 ℃, granite polishing apparatus.
The present invention compared with prior art has following outstanding advantage:
1, the granite polishing apparatus that adopts manufacture method of the present invention to produce, polished granite surface gloss can be stablized to be reached more than 85 °, not only satisfy the requirement of attractive, decorative, also improved the class of processing of stone industry product simultaneously, can create bigger economic benefit.
2, the prescription of granite polishing apparatus provided by the invention is reasonable, and it mixes use according to a certain ratio with multiple abrasive material, and they are made up for each other's deficiencies and learn from each other, and has complementary functions; Abrasive material and resin proportioning are suitable in the grinding tool in addition, between them in conjunction with firmly, in process of lapping, grinding ratio height, grinding tool long service life.
3, the grinding tool performance of the present invention's manufacturing is good, steady quality, adaptability is strong, this grinding tool uses on middle mountain construction material head factory and middle mountain Shi Ye Products Co., Ltd production line, prove that this grinding tool all has good adaptability to most of imports and homemade stone material, polishing glossiness meets or exceeds the level of import like product, is more than 85 °, and what have reaches 90 °; And the wearability of this product is than the height of import, and service life is than the length of import; Price only is 1/5 of an imported product simultaneously, can save user's production cost greatly.
4, manufacture method of the present invention is simple, convenient, easy to operate, as long as undertaken by processing step of the present invention, just can implement the present invention preferably.
