The phosphate-based additive is homogeneously distributed in the abrasive medium. The invention also relates to a method for producing corresponding thermosetting resin-bonded grinding disks.
Description
The present invention relates to being filled out by abrasive particle, thermosetting adhesive and optional other of thermosetting bondingExpect the abrasive of composition, and prepare the method for the abrasive of corresponding thermosetting bonding.
The abrasive of the application's thermosetting bonding can be the abrasive disk by thermosetting bonding, butAlso can be other abrasives, for example abrasive on base material.
Abrasive disk is made up of abrasive particle substantially, and it is pressed into abrasive disk by binding agent. Often makeWith thermosetting resin, particularly phenolic resins, phenol-formaldehyde resin modified, for example epoxy and/or rubberThe phenolic resins of modification is as binding agent. In addition, abrasive disk can also contain other fillers. ItCan be to grind active (for example cooling agent), and be therefore conducive to process of lapping orAct on the reinforcing (rupture strength, flexibility) of abrasive disk.
Abrasive on base material is made up of abrasive particle and binding agent equally substantially. But, this grindingMill mixture be not to be pressed into self-support, but as thin layer be applied to backing material (as paper,Fabric or plastics) on. For this reason, first on supporter, apply the bonding using as adhesive layerAgent layer. Then, conventionally, under the effect of electric field, abrasive particle is directionally applied on adhesive layer.In order to reinforce, second layer adhesive layer will be spread again on abrasive particle afterwards.
EP0855948 relates to abrasive, as is covered with the abrasive disk of phosphate-containing coating. At this,Described abrasive disk can be for example abrasive disk by synthetic resin bonding, its conventionally by with binding agentBe configured as together the abrasive particle composition of abrasive disk. Described coating is made up of binding agent equally, describedIn binding agent, be dissolved with not hydrogeneous inorganic metal phosphate. Therefore, phosphate additive only wrapsBe contained in the outer surface of abrasive disk. Described abrasive disk provides at gold under the energy consumption reducingThe upper available nonferromagnetic substance of metal surface (for example titanium).
DE2324222 relates to the abrasive disk with ceramic bonding, and wherein vitrified bonding contains phosphoric acidSalt additives. In order to reduce ceramic solidification temperature, in the pottery of being everlasting, add phosphate. LogicalCross and in vitrified bonding, add 10 to 20 alkali metal of % by weight or the phosphate of alkaline-earth metal,Can improve extraly the adhesive force of binding agent on abrasive particle, and the mechanical strength of milling tool. InstituteState abrasive disk solidifies at the temperature of height to 1280 DEG C.
WO2010/040472A2 relates to the abrasive particle piece of ceramic bonding. Binding agent contains aluminium conventionallySilicate, waterglass and water. In addition, binder mixtures can also contain inorganic phosphateSalt and other grinding aids or filler. In order to manufacture described abrasive particle piece, by mixed to abrasive particle and binding agentClose, wherein the primary granule of abrasive material piece flocks together. Afterwards, abrasive material piece is dry and at heightTo the temperature of 400 DEG C, solidify.
Common general knowledge in abrasives industry, abrasive particularly abrasive disk has that certain is oldChange effect. The seemingly material of the abrasive disk suction-operated to moisture of the reason of this kind of aging effect.At this, according to concept now, moisture diffusion weakened abrasive particle and its surrounding bonding matrix itBetween interface, this has caused the slight fracture of abrasive particle. Reaction is alkaline Binder Composition aggravationThis phenomenon, this is conducive to the decomposition of phenolic resin as matrix resin. Seriously shadow of this kind of aging effectRing the life-span of traditional abrasive disk.
Research (C.Stang before; " formula and moisture grind phenolic resin bonded cuttingThe impact in the life-span of mill; Plastics technology teaching post 2009, at RhodiusSchleifwerkzeugeGmbH obtains and studies) show, abrasive disk is conventionally 8 to 12After the storage time of individual month, its moisture of combination in matrix has reached saturated the putting down with environmentWeighing apparatus state. According in the moist alternation weather of DIN50016, it has 14 to 21 daysAdaptation time. Based on standardized method of testing, only just make to grind by this kind of aging effectThe average effect of mill is reduced to the about 40% to 50% of its initial effect, wherein in the starting stageEffect loss is obviously stronger, and curve flattens gradually until saturation point.
At this, it is relatively irrelevant with resin system and abrasive grain layer used that described aging effect seems.In the cycle tests stretching, by resin system, abrasive grain layer and different grinding activityTraditional modification of filler can not obtain the positive shadow of the effect maintenance aspect of life or abrasive diskRing.
So far, attempt by the aging phenomenon of suitable packaging prevention abrasive disk, for example, grindingDish is sealed in plastic foil. But, certainly only in the situation that packaging is sealing, by thisJust can avoid a bit aging effect. If packaging is opened or the diffusion impervious layer packed has exceeded and hasThe time of effect, aging effect is exactly inevitable so. Can seal again, diffusion sealingPackaging is more expensive relatively.
The object of this invention is to provide grinding of a kind of grinding effect with longer life-span and Geng GaoAbrasive material, and the use that significantly improves and do not make described abrasive that there is no a manufacturing expense is moreComplicated.
This object is by adding based on phosphatic additive solution in the abrasive to described beforeCertainly. Describedly be included in abrasive based on phosphatic additive with the concentration of 1 to 10 % by weightIn output mixture, and be uniformly distributed in abrasive.
In a preferred embodiment, described based on phosphatic additive with 1 to 5 % by weightConcentration be included in output mixture, preferably with the concentration of about 4 % by weight.
Another preferred embodiment in, with respect to the abrasive particle containing in output mixture,The described weight content based on phosphatic additive is 2 to 10 % by weight, preferably 5 to 7% by weight.
Preferably, the described phosphate that contains alkaline-earth metal based on phosphatic additive, as phosphorusAcid magnesium, calcium phosphate, strontium phosphate and barium phosphate, ferrous phosphate, ferric phosphate, manganese phosphate, phosphoric acidAluminium and trbasic zinc phosphate, phosphate synthetic or mineral, and their mixture. Particularly preferablyGround, described is calcium phosphate based on phosphatic additive,, as Dicalcium Phosphate or its acid anhydrides,Or monetite or brushite, tricalcium phosphate or hydroxyapatite or triphosphate hydroxy pentacalcium(Ca5(PO4)3OH), fluor-apatite, di(2-ethylhexyl)phosphate magnesium, tricresyl phosphate magnesium, biphosphate magnesium, or itMixture. Preferably, described is water-fast based on phosphatic additive, andIn the time preparing abrasive, there is not chemistry or physical change.
Abrasive of the present invention uses any thermosetting resin as binding agent. Preferably, useSynthetic resin is as the phenolic resins of phenolic resins or modification, the phenol of for example epoxy and/or modified rubberUrea formaldehyde is as binding agent.
Preferably, in the output mixture of abrasive, the content of binding agent is 1 to 40 % by weight,Preferably 5 to 30 % by weight, and be particularly preferably 10 to 20 % by weight.
Can use sodium cryolite, elpasolite, potassium aluminum fluoride, iron sulfide, zinc sulphide, sulphurChange manganese, manganese chloride, copper sulfide, chalcopyrite, pyrite, ferrous oxide, iron oxide, four oxygenChange three-iron, lime, chalk, the variant of carbon is as graphite, carbon black, coal, and theyMixture is as filler.
So far, in food industry for example, use tricalcium phosphate (TCP) as acid regulator, strongAgent or release agent. For fear of the discrete material caking to moisture-sensitive, also can use itAs so-called " sprinkling auxiliary agent ". Wherein, the concentration using is conventionally in percentage positionIn scope. In addition, well known to a person skilled in the art to be, due to the ratio table of large powder particleArea is (up to 70m2/ g), TCP can reversibly adsorb based on particle self at particle surfaceWeight is up to the moisture that exceedes 10%.
Experiment is widely verified, by adding based on phosphatic additive, can improve rootAccording to life-span and the effect of abrasive of the present invention. Be apparent that, phosphate additive has stoped logicalCross the intrusion of moisture and corrode and damage the bonding between abrasive particle and binding agent.
Be known that the adsorption capacity of the moisture that for example TCP had. But because moisture is logicalCross TCP only to adsorb potentially or reversibly, so those skilled in the art do not expect to lead toCross and add this kind and can improve the abrasive boning by synthetic resin based on phosphatic additiveLife-span. Especially, do not expect and also not accurately do not explain so far, by this kind of sideFormula makes to be improved according to the nonferromagnetic substance of abrasive of the present invention.
That phosphate additive is in the system of abrasive according to another advantage of abrasive of the present inventionIn standby, there is not physics or chemical change. So can be by X-ray diffraction the ash at abrasiveChange the apatite phase that detects clearly crystal in residue. In addition can spread out by X ray,Penetrate exactly quantitatively phosphatic content in ash residue, and therefore calculate basisThe phosphatic content of abrasive composition.
Abrasive of the present invention can be abrasive or other grindings arbitrarily on abrasive disk, base materialMaterial. At this, the output mixture of the abrasive on base material and the abrasive using (abrasive particle,Binding agent, additive) weight percentage weight indicate relevant. Wherein, the weight of base materialAmount is not very done the weight of output mixture.
In addition, the application's content is prepared with abrasive disk based on phosphatic additive in additionMethod, is wherein saidly included in and grinds with the concentration of 1 to 10 % by weight based on phosphatic additiveIn the output mixture of mill, and be uniformly distributed in abrasive. Described method comprises preparationThe step based on phosphatic additive of powder type, by powder type based on phosphaticThe step that additive and abrasive particle, binding agent and other optional fillers mix, by output mixtureInject the step of the mould of for this reason preparing in advance, add the step of glass fabric, mixture is pressedMake the step of base substrate, and curing base substrate obtains the step of abrasive disk.
Preferably, preparation according in the method for abrasive disk of the present invention, first by powder typeMix with abrasive particle based on phosphatic additive. Afterwards, by this mixture and binding agent with appointOther fillers of choosing mix. By strongly mixing, phosphate additive is in output mixtureWith all distributions equably in the abrasive disk completing.
Conventionally be exactly conventional abrasive according to the preparation of the abrasive on base material of the present invention,Preparation on base material. But be noted that at this additive in abrasive reaches equalEven distribution. Particularly in the time that abrasive particle is applied on base material by electrostatic means, in order to ensure to grindBeing uniformly distributed of additive in abrasive material, by mixed to additive and adhesive layer and tectal binding agentIt can be favourable closing.
According to figure below, further illustrate abrasive of the present invention and prepare its method. Figure has:

The preparation of abrasive disk
For the favourable characteristic according to abrasive of the present invention is described, contrast is had to phosphateThe grinding effect of the phenolic resins abrasive disk of the grinding effect of the abrasive disk of additive and tradition preparationReally. In table 1, provide the general introduction of the abrasive disk of research.
Table 1: the abrasive disk of research
The abrasive disk (experiment numbers 13290.1 and 13290.2) of embodiment 1 and 2 comprise toThe alumina grain with granularity F46 and F60 of 65 % by weight. First by abrasive particle and 4 % by weight(corresponding 3 to 5 μ TCP m) mixes the particle diameter D50 that has of fine-powdered. Afterwards to mixtureIn add the liquid phenolic resin of 7.5 % by weight. Then this mixture is added and has 10.5 weightsPhenolic resins and active filler (the namely ice crystal of 10 % by weight and 3 of the powder type of amount %The potassium aluminum fluoride of % by weight) container in, and wish machine,massing strong stirring by Airy30 minutes. In order to remove bulk, by the granular output mixture 2mm so preparingThe sieve screening of sieve aperture. Afterwards the particle of weighing is distributed in mould, adds glass fabric, markLabel and flange ring are also pressed into idiosome. Finally by little idiosome co-curing 18 under the high temperature of 185 DEG CTime. The abrasive disk of embodiment 1,2,4 and comparative example 1 has radius and the 1mm of 125mmThickness.
By identical method preparation contrast abrasive disk 1 and 3, wherein this contrast disks is not having certainlyHave in the situation of TCP additive and prepare. In other words, this kind of dish correspondingly contains more fillers.
The abrasive disk of embodiment 2 uses the component identical with the abrasive disk of embodiment 1. But,The abrasive disk of embodiment 2 is prepared some improvement of method. Not to sneak into abrasive particle by TCP,But sneak into the mixture being formed by phenolic resins and the active filler of powder type.
Conventionally, as with the abrasive disk abrasive disk of Preparation Example 4 in the same manner of embodiment 1. ButBe, the abrasive disk of embodiment 4 uses different phosphate additives, namely Dicalcium Phosphate acidAcid anhydride (CaHPO4). DCP acid anhydrides is also referred to as phosphoric acid hydrogen one calcium, and with monetite or calcium thoroughlyThe natural form of phosphorus stone is contained.
The abrasive disk of embodiment 3 and comparative example 3 has the size of 230 × 1.9mm.
The research of the grinding effect to abrasive disk
In order to analyze the grinding effect of abrasive disk, abrasive disk is carried out to standardized measure of merit,Namely automatically test and manual test. At this, abrasive disk is all by identical grinding testProgram.
The auto testing instrument using in automatic test is by forming with lower device, wherein angle grinding machine(Flex company, 1400W) be contained on lever arm and lever arm by motor and fixing enteringMaterials device moves up and down together. At this, in the time declining, cut about 2 to 3mm wide one sectionSteel pipe (V2A15 × 15 × 1.5mm). After rising, supplement pipe by automatics,Make to cut again one section of steel pipe while once declining upper. Auto testing instrument is the residue of mensuration dish constantlyDiameter, and record the number of times of cutting process. In the time that the residual diameter of abrasive disk reaches 95mm,Auto testing instrument stops test.
In manual test, tester's operation angle grinding machine (Flex company, 1400W). WithThe cutting quantity of before setting is cut complete material V2A. At this, described complete material (fourRib rod V2A, 25 × 25mm) be installed on vice. At this, grinding effect exists by contrastLap diameter before test and is afterwards measured. At this, it is grinding effect that average mill damagesMeasure.
In Fig. 1, displaying be embodiment 1 and 2 and the abrasive disk of comparative example 1 at pipe V2A15The result of the automatic test on × 15 × 1.5mm.
To a part of abrasive disk, grind test and carry out immediately after preparation. At this time pointUpper, the grinding effect of abrasive disk is maximum. In order to study the impact of moisture on grinding effect,The abrasive disk of other parts is hung and stored separately in environmental chamber, and apply according to DIN50016 moist alternation weather. In this kind of environmental chamber, storing 14 to 21 days about correspondences grindsMill stores 8 to 12 months in common Europe, middle part weather conditions. As discussed above, by phenolic resin bonded abrasive disk after this storage time, with abrasive disk materialIn conjunction with moisture conventionally reach poised state, and the grinding effect level that reaches capacity.
After the different storage times of 3,7,14 and 21 days, test body is taken out respectively alsoMake it similarly through grinding test program. In Fig. 1, show standardized effect value phaseTo the diagram in storage time. The abrasive disk (storage time: 0 day) of testing immediately after preparationShow the highest grinding effect. The quantity of the cutting that can carry out with this abrasive disk can be markedStandard turns to 100%. Learnt by Fig. 1, the grinding effect of contrast abrasive disk 1 (namely carries outThe quantity of cutting) along with the increase in storage time reduces constantly, and in the time of the storage of 21 daysBetween after approached 50% grinding effect of approximately initial effect. The abrasive disk of embodiment 1 and 2Grinding effect reduce along with the increase in storage time equally. But described test clearlyDemonstrate, compared with the saturated grinding effect of the contrast abrasive disk 1 of preparing with conventional method, grindThe amount of the reduction of effect is less and after the storage time of 21 days, reach higher higher than 60%Saturated grinding effect.
Unexpectedly, the abrasive disk of embodiment 1 shows other favourable effects. Embodiment1 abrasive disk has and compares the initial grinding effect higher than abrasive disk 1. Embodiment's 1After preparation, the abrasive disk of test has stood 237 times reaching before the residual diameter of 95mm immediatelyCutting. Relatively, 1 of abrasive disk of contrast may be realized 208 cuttings. This explanation is according to thisThe abrasive disk of invention has about 14% effect promoting than contrast abrasive disk 1.
From above-described embodiment 1 (experiment numbers: the abrasive disk that repeats test 13290.3) existsAutomatically in test, show and on pipe V2A15 × 15 × 1.5mm, there is the initial of 241 cuttingsEffect. In order to study saturated grinding effect, this dish is placed in environmental chamber to 69 days (2 months1 week again). Even after being exposed to so for a long time in alternation weather, standardized residueEffect still old original effect 59% (pipe V2A15 × 15 × 1.5mm upper in automatic testIn there is 141 cuttings). This shows, and is placed on the effect of the grinding after 21 days in alternation weatherThe saturated grinding effect really of fruit, even and if still do not occur after the longer time of stayingDue to the significant change of the grinding effect of condition of storage.
Interestingly, the abrasive disk of embodiment 2 can only carry out 189 cuttings. AlsoBe to say, the initial effect of the abrasive disk of embodiment 2 is lower by 10% than the initial effect of traditional dish.Significantly, when its reason is to prepare abrasive disk, add the mode of TCP additive. Although implementExample 1 has respectively and compares the effect retention that traditional abrasive disk improves with 2 abrasive disk,But the abrasive disk that only has embodiment 1 provides the additional advantage of higher initial effect.
The standard of the abrasive disk that Fig. 2 has shown Fig. 1 on complete material V2A25 × 25mmThe effect value of changing. In this test, carry out respectively 10 cuttings, measure afterwards the surplus of abrasive diskRemaining diameter. The result of the automatic test that result is described with Fig. 1 qualitatively conforms to. At manual testIn also show, the grinding effect of the abrasive disk of embodiment 1 and 2 substantially higher than contrast grindThe grinding effect of dish 1. Especially, the result after storing for 21 days shows, contrast abrasive disk 1Saturated grinding effect be approximately and be less than 50%, on the contrary, the abrasive disk of embodiment 1 and 2Saturated grinding effect has the value of approximately initial effect 60% all the time.
The possibility of result that some waves in manual test is because abrasive disk takes out from environmental chamberTime point. Because (particularly) in the time that the storage time is less than 21 days, may also not reachMoisture absorption saturated, so may in the time taking out abrasive disk, be occupied the majority at this grinding effectMoisture effects. In addition also must consider, tester's state.
The grinding of abrasive disk and the contrast abrasive disk 3 of embodiment 3 has been described in the diagram of Fig. 3The result of performance. In this test, measure according to the material V2A25 × 25mm completeOn the effect of abrasive disk of manual test and aging. At this, each abrasive disk carries out 20 times and cutsCut, and test the wearing and tearing of dish measuring diameter dish before and afterwards by measurement. Result also againDemonstrate the active influence that TCP additive keeps the effect of abrasive disk. In addition contrast disks,3 cut to carry out 19 times only after the storage of 21 days again, and residual diameter does not allow completeMaterial V2A25 × 25mm on cut again. As described in Fig. 3, lack in concernIn the situation of cutting, traditional abrasive disk only reaches afterwards and compares initial grinding effect the storage of 21 daysThe grinding effect of fruit less than 15%. Relatively, the grinding effect of the abrasive disk of embodiment 3 is 21After it, reach about 50% saturated grinding effect.
In addition, this test shows again, and initial grinding effect, namely according to of the present inventionThe grinding effect (storage time: 0 day) that abrasive disk is tested immediately after preparation is than contrastThe initial effect of abrasive disk 3 is higher. The abrasive disk of embodiment 3 only has after 20 cuttingsThe wearing and tearing of 15.7mm, and contrast abrasive disk 3 has the wearing and tearing of 16.2mm. More unexpected, contrast abrasive disk has than the abrasive particle of many 4 % by weight of the abrasive disk of embodiment 3, and thusWhat expect is the initial effect of higher contrast abrasive disk. Because initial nonferromagnetic substance also not byThe moisture absorption impact that abrasive disk material is possible, so better grinding effect can not only pass throughThe characterization of adsorption of TCP additive is explained. Certainly have much other effects, TCP adds thusAdd the grinding effect that agent has improved synthetic resin abrasive disk.
The abrasive disk of embodiment 4 is carried out to identical measure of merit. As previously discussed, this grindsThe formula of mill is identical with the formula of the abrasive disk of embodiment 1, except using DCP acid anhydrides to replaceTCP. At this, DCP is added to abrasive particle equally. The initial grinding effect of the abrasive disk of embodiment 4Automatically thering is the cutting of 258 times in test, namely than the abrasive disk of aforesaid embodimentInitial effect is higher. But, in the automatic test at pipe on V2A15 × 15 × 1.5mmAfter 14 days aging, do not demonstrate obvious good effect. In this test, average residueEffect is 52% of initial effect.
The result of the grinding test of the abrasive disk of embodiment 4 has been described in the diagram of Fig. 4. RightMore identical with the contrast disks of Fig. 2 than dish. But in manual test (at complete material V2A25The upper cutting of × 25mm 10 times), 78% standardized effect ratio of the initial effect after seven days56% the residual effect of this time of comparative example is obviously higher. After 14 days aging, 66% surplusResidual effect fruit is more significantly higher than 32% residual effect of comparative example. Until the application's applicationDay, these experimentalists and technicians still do not complete, and this makes to provide the abrasive disk 21 of embodiment 4Grinding effect after it.
Aforesaid embodiment only relates to the abrasive disk of synthetic resin bonding. But set out thus, phosphorusThe abrasive of other thermosettings bondings of salt additives to the abrasive on base material for example also existsFavourable effect.
