Abstract
The present invention relates to a grinding and polishing material. It is composed of (wt%) 28-78% of synthetic abrasive, 20-60% of resin adhesive, 1-15% of loosening agent and 0.1-15% of hardening agent. Said invented synthetic abrasive-stone is simple in making method, low in cost, and suitable for radiation and cutting of various grinding processes, and its cutting machinability is excellent, so that it can obtain optimum rubbing and grinding effect.
Description
The invention belongs to a kind of abrasive polishing materials, particularly the emery wheel used of gravure plating attrition process.
The ground finish of the copper flower roller critical process that is absolutely necessary in the fields such as color printing of textile printing and dyeing, paper printing, plastic film, grinding stone is the critical material in the grinding technics.Gritstone is cheap, but impure in the grinding stone, scratches the version roller easily, the cutting force instability, and out-of-shape is used inconvenience, and easy-weathering is deposited inconvenience.Development along with the plate-making industry in order to overcome the deficiency of gritstone, the cellular plastic grinding stone occurred, its structure is meticulous, rubbing down subject range is extensive, and the grinding accuracy height gets final product the dry type ground finish, again can warm formula ground finish, but plastics stone complex manufacturing, the cost height, cutting force is less simultaneously, efficient is not high, and the life-span is short.
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of manufacturing process simple, product cost is low, efficient height, the synthetic grindstone that the life-span is long.
Synthetic grindstone of the present invention is made up of compound abrasive, resin glue, raising agent and solidifying agent, and its proportioning (weight ratio) is: compound abrasive 28-78%, resin glue 20-60%, raising agent 1-15%, solidifying agent 0.1-15%.Abrasive material in the grinding stone requires to have suitable hardness, granularity and precision, and the different purposes of foundation can be selected the abrasive material of different model, specification, as: brown corundum (Al
2O
3), white fused alumina (Al
2O
3), chromium corundum, single alundum, microcrystal fused alumina, green silicon carbide (SiC), black silicon carbide (SiC).
Abrasive material need connect into grinding stone integral body with binding agent, and binding agent should have good surface wettability with abrasive sand, and enough adhesive fastness are arranged, and should be suitable for various working conditions in addition, as water-soaked, high temperature, low temperature, acidity, alkalescence etc.But, if abrasive material is bonding firm excessively, when it the cutting edge blunt after, still staying does not come off on the grinding element just can't work again.Grinding stone should have the function of making a fresh start, and promptly abrasive material will have suitable cohesive strength, after grinding for some time, blunt sand grains should come off voluntarily, making newly has sand grains to expose out.It is too fast to make a fresh start, and grinding stone self abrasion are strengthened, and it is slow to make a fresh start, and then cutting effect is not good.Resin glue can satisfy these requirements well, as urea-formaldehyde resin, trimerization chloramines formaldehyde resin, Melamine resin sheet, aniline formaldehyde resin etc., wherein especially based on urea-formaldehyde resin or from adhesive effect the best of urea-formaldehyde resin.
Grinding stone can produce very big heat in the high-speed grinding process, must in time take away, and in addition, the metal that grinding is got off or the smear metal of other material must be cut off rapidly, could guarantee that like this grinding carries out continuously, guarantees smooth finish and precision simultaneously.These just require that suitable gap and pore are arranged between abrasive material.And gap or air holes need to add raising agent in grinding stone.Raising agent can be selected following a kind of or several mixture wherein: powder, titanium dioxide, potato powder, starch, ultra-fine wood powder, ultra-fine wheat-flour, Semen Maydis powder, peanut hull meal on Paris white, talcum powder, the high mountain range.
Tackiness agent solidifies as early as possible in the synthetic grindstone in order to impel, and needs to add solidifying agent, and solidifying agent can be selected hexamethylenetetramine, ammonium sulfate, ammonium chloride.
Synthetic grindstone of the present invention during fabrication, at first to select abrasive material, resin glue, raising agent and solidifying agent, be mixed in proportion, stir into the pasty state uniform mixture, inject mould, under the condition of heating or not heating, aftershaping depanning through about 2-15 hour, machining and shaping gets final product after going out needed size.
Synthetic grindstone of the present invention can be selected varigrained abrasive material for use, makes the synthetic grindstone 60#-2000# of multiple model, can finish complete processings such as the corase grind in the use, middle mill, correct grinding.
Synthetic grindstone of the present invention has following advantage:
1, manufacture method is simple, and is with low cost, is suitable for the heat radiation and the chip breaking of various process of lapping, and cutting ability is good, can reach best ground effect, easily makes different shape, carries out secondary processing easily, can satisfy the requirement of user to geomery.
2, caking agent and abrasive material content are moderate, have suitable wear resistance ratio; Have enough physical strengths, be suitable for the grinding of dry type, the various conditions of wet type.
3, have excellent chemical stability, excellent resistance to chemical attack, solvent soaking and have water tolerance does not constitute corrosion to version roller and equipment.
Be three embodiment of the present invention below, used raw material not only limits to these three kinds, just for illustrating.
Embodiment 1:
Palm fibre corundum 1400 grams, aniline formaldehyde resin 2750 grams, potato powder 400 grams, ammonium chloride 400 grams, mixing and stirring is gone into mould, and under 50 ℃ of conditions, after 15 hours, the material forming depanning goes out needed physical dimension through mechanical specific equipment shaping and gets final product.
Embodiment 2:
White fused alumina 3900 grams, urea-formaldehyde resin 1000 grams, starch 50 grams, six its time of first amine 50 grams, mixing and stirring is gone into mould, and manufacture method is with embodiment 1.
Embodiment 3:
Silicon carbide 1000 grams, urea aldehyde Melamine resin sheet 3000 grams, Semen Maydis powder 750 grams, ammonium sulfate 750 restrain, mix, and manufacture method is with embodiment 1.
