Present invention firstly provides a kind of resin wheel formula, including mass fraction be 27.29% resin, 16.01%
Diamond, 17.21% silicon carbide, 6.86% diamantane, 9.22% ice crystal, 5.53% dolomite, 8.31%
Titanium oxide and 9.56% cerium oxide.
For its manufacturing process, can manufacture in the following manner:
1, cold-press process: mainly including mixing and compacting and curing schedule.
The bonding agent that cold-press process uses has wetting agent and powdered resin, and be typically used as wetting agent has liquid phenolic tree
Rouge, furfural, furfuryl alcohol, cresols etc., most is liquid phenolic resin.
Determine liquid resin and powdered resin use ratio (being generally termed liquid powder ratio) because being known as: abrasive grain is distributed,
Wire feeding, amount of filler, the viscosity of liquid resin, property of powdered resin etc..
If the viscosity of liquid resin is bigger, abrasive surface is coated completely and just needs more liquid resins；It abrasive material and fills out
The granularity of material is smaller, and specific surface area is bigger, and the dosage of liquid is also more.
The molecular weight of powdered resin is higher, free phenol is lower, poorer with the adhesive force of liquid resin, the liquid needed
It measures more.Above several situations are both needed to improve liquid powder ratio.
Generally make wetting agent with liquid resin, liquid powder is than selecting 1:2 to 1:4, and with the mixing of furfural or furfuryl alcohol and carbolineum
Object makees wetting agent, and liquid powder is than selecting 1:6 to 1:8.
Batch mixer will pass through process certification, can reach ideal mixed effect and not damage abrasive material and be preferred.
Mixing time after fine powder is added is generally 2 to 5 minutes, too short to cannot be guaranteed that mixing is uniform, too long resin film
It is easy to fall off, and material temperature is caused to increase, resin gives solidification.
1. mixing program: first by abrasive material, usually combination grain, give mixed, add wetting agent, uniform wet mill
After material, then mixed powdered resin addition will be given with other fleuts, continuesd to mix to uniform.Mixed abrasive material to have compared with
Good plasticity and mobility, material cannot be overly wet, is otherwise easy agglomeration, can not have powder ball, while guaranteeing the flowing having had
Property, to guarantee that injection molding is abundant, the general method using sieving removes agglomeration.Judging the method for material plasticity quality is: grabbing one
Mixed material, being gently pinched with hand agglomerating will be preferred.
Granular material is generally added to powder ball easy to form in the abrasive material soaked, is gradually eliminated at present, is used now
It is more be double pot mixing methods, be exactly first to mix abrasive material in a batch mixer with wetting agent, while another mixing
Powdered resin and other fleuts are mixed in machine, then the abrasive material soaked is poured into powder, is uniformly mixed.Double pots
The advantages of mixing is can not only to generate powder ball, but also be avoided that pollution, is readily cleaned material pot.
After mixed material is sieved, it can for suppressing.
2. compaction procedure: mold being installed, the required abrasive material measured is weighed and inserts mould cavity, suppressed after striking off.It needs
Place being put into as required for enhancing glass mesh sheet.Then it pressurizes at room temperature, the pressure limit being generally cold-pressed is 15 to 30N/
Mm2, preferably 15 to 25N/mm2.The selection of pressure size depends on the plasticity of material and grinding wheel requires the density reached.No
Excessively high pressure is preferably used, otherwise abrasive material can be crushed.Pressing time is generally 5 to 50 seconds, preferably 5 to 30 seconds, and the time is long
The quality of the short density and shape and the plasticity of material for requiring to reach depending on grinding wheel.Then grinding wheel can be taken out into
The operation of row next step is to having cured.
3. program curing: curing operation can be placed in fixed curing oven and carry out, can also be solid in the tunnel type of flowing
Change and is carried out in kiln.Solidified with curing oven, the riding position of grinding wheel is especially important, generally by grinding wheel steel or the disk of pottery
It is fixed, to guarantee that grinding wheel is indeformable in the curing process, be uniformly placed in furnace, to have air circulation in furnace so that each position by
It is hot uniform, then start temperature program and is solidified；Solidified with tunnel type curing kiln, first by grinding wheel steel or the circle of pottery
Disk is fixed, then is placed into trolley, is pushed into tunnel, is run by setting speed.General initial temperature is 60 to 80 DEG C, final temperature 160
To 190 DEG C, entire solidification process needs the used time 20 to 25 hours, is finally cooled to 40 to 60 DEG C, opens fire door, that is, can be taken off grinding wheel
?.
Physical and chemical changes occur in entire heating process, following react mainly occurs for each temperature stage:
Resin starts to melt at 80 DEG C, has moisture content to steam, and curing reaction starts；
It decomposes at 110 DEG C and the resin of melting is promoted to crosslink for six times, while releasing the gases such as ammonia gas and water；
110 to 180 DEG C of resins be crosslinked until being fully cured, a large amount of ammonia release.
High-temperature region overlong time will lead to crossing for resin and solidify, and while Wheel hardness increases, lead to the intensity of grinding wheel
Decline generally requires to select different cure profiles and solidification final temperature according to the different of grinding wheel.
Final temperature is 165 to 170 DEG C, grinding wheel good toughness firmly；Final temperature is 175 to 180 DEG C, and grinding wheel is hard；Final temperature be 185 to
190 DEG C, grinding wheel is hard and crisp.
2. half heat pressing process:
The press temperature of half heat pressing process is generally 50 to 65 DEG C, remaining technique and cold-press process are completely the same.At this
The viscosity of liquid resin becomes smaller under press temperature, can be good at combining together powdered resin, makes the stream of entire resin system
Dynamic property improves, it is easier to sufficiently penetrate each space, even if the pressure of press is less high, also can be good at forming, when pressure maintaining
Between do not need yet it is too long, especially suitable for the automation pressing production line worked continuously.
3. heat pressing process:
Heat pressing process is generally used for the grinding wheel of manufacture greater density, and the density of plain wheel is generally 2.4 to 2.7g/cm3,
Highest 2.9g/cm3, and the density of high density grinding wheel will reach so high density up to 3.1 to 3.5g/cm3, heat pressing process
It is most suitable.The mixing requirement of heat pressing process is different from cold-press process, generally uses dry pigmentation, or with less than abrasive material weight
1% furfural of amount makees wetting agent and moistens abrasive material, then is uniformly mixed with powdered resin.Powdered resin generally selects fluidity small
, suitable range is 15 to 20mm even more small, cannot be because of heat using the big powdered resin of liquid resin and fluidity
Excessive rouge is easy when pressure.
Compaction procedure: press temperature range is 160 to 170 DEG C, and the pressing time is 30 to 60 seconds/millimeters of grinding wheel thickness, example
The grinding wheel of a 60mm thickness is such as suppressed with reference to claimed below:
Pressure: 20 to 40N/mm2；Press temperature: 150 to 170 DEG C；Pressing time: 30 to 60 minutes.
In pressing process, to deflate once or several times in 4 to 8 minutes after giving pressure.
Program curing: the grinding wheel after hot pressing has had comparable intensity, but to reach optimal performance still will be into
Row curing process.Solidification temperature is 160 to 180 DEG C, curing time 8 to 12 hours.
After using above-mentioned formula and manufacturing process, the present invention is also manufactured that a kind of resin wheel, is particularly convenient for
The processing of ceramic mobile phone shell.
Specifically, as shown in Figure 1 and Figure 2, including prismoid section, it is set to the grinding ring of frustum big end, is set to frustum small end
