Background technology

The common grinding tool that is applicable to material surface grindings such as lithotome, artificial board, Ceramic Tiles, refractory material and concrete plate, polishing usefulness is at normal temperatures by the hydration reaction be combined into materials such as magnesia, magnesium chloride, carborundum, the magnesium material that contains wherein accounts for about 60% in product, as disclosing a kind of manufacture method of quick manufacturing grinding and polishing grinding tool among the Chinese patent literature CN1600501A, component and weight proportion that it comprises are: the magnesium chloride solution (MgCl of 28%, 31 ° of Baume degrees of magnesia (MgO) 2) 30%, magnesium sulfate (MgSO4) 2%, liquid phenolic resin 2%, powdered phenol-formaldehyde resin 10%, 240# to 1200# carborundum 15%, alumdum (Al 2O 3) 3%, corundum (Al 2O 3) 10%, in the carborundum, alumdum and the corundum compound abrasive that stir magnesia and other various granularities, add phenol-formaldehyde resin powder, add magnesium chloride again, evenly the liquid phenolic resin allotment.Must have on mould after the product cast and in drying baker, be heated to 185 ℃, make the phenolic resins in the product reach certain intensity and hardness.In addition, carborundum is artificial synthetic, whenever produces 1 ton of finished sand and approximately need consume nearly 10,000 degree electricity, cost of manufacture height.

At the many polissoirs of processing continuously based on 16～24 mills of processing of stone industry, at the many polissoirs based on the continuous processing of 28～40 mills of ceramic processing industry, wherein, each mill is installed 6 grinding tools.With regard to ceramic processing industry, this grinding tool wearability when reality is used that contains magnesium is relatively poor, the energy consumption height, the operating current of each processing polishing grinding pan is 14～20 peaces, pressure is 2～4kg, must change a grinding tool in average per 2 hours, its relative processing cost is higher, it changes frequent in addition, labor intensity of operating staff is big, and every day every production line only because the consumption of grinding tool self just will produce mud and the sewage of approximately amounting to 2 tons of weights of siccative, the processing of these mud and sewage causes great trouble to enterprise, simultaneously also bring bigger negative effect to surrounding enviroment

Summary of the invention

The epoxy resin that technical problem to be solved by this invention is to provide that a kind of cost of manufacture is low, with short production cycle, anti-wear performance is good, intensity is high, operating pressure is little, long service life, energy consumption are low is in conjunction with the grinding tool of abrasive compound, to overcome weak point of the prior art.

The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of epoxy resin is in conjunction with the grinding tool of abrasive compound, the component that it is characterized in that grinding tool comprises epoxy resin, abrasive material and curing agent, its percentage by weight is followed successively by: epoxy resin 15～78%, abrasive material 2～44%, curing agent 4～18%, wherein, abrasive material comprises one or more the combination in diamond, carborundum or the corundum, curing agent comprises 4.4 '-one or more combination in methylene dianiline, solid diaminodiphenyl-methane or the liquid modifying diaminodiphenyl-methane.

The component of above-mentioned grinding tool also comprises other auxiliary material, these other auxiliary material comprise one or more the combination in aluminium oxide, barium chloride, sodium chloride, quartz sand, organobentonite, wetting agent, zirconium silicate, calcium carbonate, graphite powder, garnet, magnesium sulfate, phenolic resins, zinc stearate or the dolomol, wherein, the occupied percentage by weight of other auxiliary material is: 2～66%.

This product can be made into the arbitrary shape identical with existing product, and grinding and polishing applicable to various types of material surfaces such as lithotome, artificial stone, pottery, refractory material, concrete can be applicable to various grinding-polishing equipment, and be applied widely.

Provided by the invention with epoxy resin, abrasive material, curing agent and other auxiliary material in conjunction with and the grinding tool made has characteristics such as energy-conservation, efficient, environmental protection, be embodied in: the work period of this product is 88～100 times of existing product work period, improved production efficiency greatly, both alleviated operating personnel's working strength, also reduce corresponding operating personnel's quantity, reduced cost of manufacture; Owing to use new product, the operating pressure that is applied in its course of work on each mill only is 1～2kg simultaneously, and its operating current is 8～9 peaces, cuts down the consumption of energy about 40% with respect to former existing product 2～4kg operating pressure, 14～20 operating currents of pacifying; Because the reduction of operating pressure, fault rate, the maintenance rate of corresponding production equipment also decline to a great extent, and work noise reduces, and operating personnel's working strength further is reduced; This product anti-wear performance is good, intensity is high, good toughness, average every day, every production line only consumed the grinding tool about 25kg, consequently directly reduce the consumption of grinding tool and the generation of residue, both reduced the difficulty that the user handles discarded object and waste water, also reduced negative effect surrounding environment.

Product provided by the invention has also reduced the use amount to carbofrax material significantly owing to do not re-use magnesium oxide material, for China save mine resources and cut down the consumption of energy provide one can practicable road.

The present invention has that cost of manufacture is low, anti-wear performance good, relative processing cost is low, intensity is high, operating pressure is little, long service life, characteristic of low energy consumption.
