Detailed description of the invention
With reference to accompanying drawing, abrasive brush of the present invention is described.
As shown in Figure 1, abrasive brush 10 comprises multiple bristle 11, and multiple bristle 11 comprises the diamond particles as abrasive grains.
Bristle 11 is by combined around the bond material 12 of their periphery 11a, and wherein, the end 11b of the multiple bristles 11 through combining is kept by brush retainer 13.
In the present embodiment, brush retainer 13 comprises patchhole 13a and holding member 13b, the end 11b of multiple bristle 11 is inserted in each patchhole 13a, holding member 13b is easily fastened to the driver part of abrasive brush device (clamp structure 21 in Fig. 2 corresponds to this driver part) or is removed from the driver part of abrasive brush device, and this driver part drives abrasive brush.The end 11b of multiple bristle 11 is fastened to patchhole 13a by such as adhesive.
Bristle 11 is the monofilament be made up of mylar, and this monofilament has circular cross section and comprises abrasive grains, and abrasive grains is diamond particles, and the surface coverage of diamond particles has nickel or the metal alloy primarily of nickel formation.By melt spun polyester resin after mylar is mixed with the abrasive grains of scheduled volume and therefore manufactured these monofilament by melt-spun by making mylar extend in the case of necessary.
Use the mylar of the abrasive brush 10 of thus obtained bristle 11 than be conventionally used as into monofilament nylon resin more firmly and more flexible.Therefore, it has larger grinding force.In addition, diamond particles can have the grinding force of increase, and this diamond particles has high hardness, and is exposed on the surface of monofilament.
The mylar used in the present invention comprises PEN (polyethylenenaphthalate), PETG (polyethylene terephthalate), poly terephthalic acid methylene ester (polymethylene terephthalate), poly terephthalic acid tetramethylene ester (polytetramethylene terephthalate), polytrimethylene-terephthalate (polypropylene terephthalate), poly-naphthalenedicarboxylic acid methylene ester (polymethylenenaphthalate), poly-naphthalenedicarboxylic acid tetramethylene ester (polytetramethylenenaphthalate), poly-naphthalenedicarboxylic acid propylidene ester (polypropylene naphthalate), or comprise in these mylar any one as Main Ingredients and Appearance copolyester.
The mylar used in an embodiment of the invention is the polymer of NDA second diester (ethylene-2, the 6-naphthalate) unit comprising 60mol% (molar percentage) or more.Therefore, suitable PEN resin can be used.Because of the monofilament be made up of the mylar of NDA second two ester units comprising 60mol% or more, there is higher rigidity and grinding force therefore can be made to increase, so preferably use this monofilament.If PEN resin is less than 40mol%, mylar can comprise dicarboxylic acids composition and the such as ethylene glycol of such as terephthalic acid (TPA), M-phthalic acid and phthalic acid and so on, the diol component of propane diols and tetramethylene glycol (tetramethylene glycol) and so on.
The metal alloy that the abrasive grains of bristle 11 is formed as making the surface coverage of diamond particles to have nickel or form primarily of nickel.The abrasive grains used in the present embodiment is diamond particles, and the surface of this diamond particles is coated with nickel by plated by electroless plating.
Usually, diamond particles without any the configuration determined and the recessed and evagination (roughness) on surface be restricted.Therefore, as fruit granule mixes with resin material with this configuration, then the adhesion between particle and resin material is little, and particle is often easy during grinding comes off from bristle.When by nickel or primarily of nickel form metal alloy cover time, define the recessed and evagination larger than the recessed and evagination on the surface of diamond particles, thus, create effect particle being fixed to resin material, make particle be not easy to come off from bristle.By this way, abrasive brush of the present invention can continue grinding in a long time, and keeps high grinding force.
The various method on the surface in order to cover particle except plated by electroless plating can be used, as performed plated by electroless plating after the spray application and physically nickel or metal alloy being attached to diamond particles by means of mechanical presses (ironing).
The 45-65wt% (percentage by weight) of the total amount of abrasive grains is preferably for the nickel that covers or the amount of metal alloy that forms primarily of nickel.If described amount is lower than 45wt%, then on the surface of abrasive grains, fully do not form recessed and evagination, and adhesion between abrasive grains and bristle is little.Therefore, will come off during grinding than relatively large abrasive grains, and the efficiency of grinding will decline.If described amount is higher than 65wt%, then the ratio on the abrasive grains surface exposed will reduce.Therefore, the efficiency of grinding will reduce.
If the diameter of diamond particles is comparatively large, then grinding force increases, and causes grinding efficiency to improve.If the diameter of diamond particles is less, then can not obtain large grinding force.But the roughness that it is possible to the surface making to be ground object becomes more level and smooth.The average diameter of diamond particles is preferably 5-150 μm (micron).If described average diameter is less than 5 μm, then can not obtain enough grinding forces.If described average diameter is greater than 150 μm, the intensity of the monofilament of bristle reduces, and they become easy fracture.
With 100pts.wt (weight portion) for benchmark, the amount being included in the abrasive grains in bristle 11 is preferably the 10-40pts.wt of bristle 11 (mylar).If described amount is lower than 10pts.wt, then on the surface of bristle 11, do not expose the abrasive grains of q.s, and enough grinding forces can not be obtained.If described amount is higher than 40pts.wt, then the intensity of the monofilament of bristle reduces, and they become easy fracture.
The diameter of bristle 11 (monofilament) is preferably in the scope of 0.4-1.0mm (millimeter).If described diameter is less than 0.4mm, then bristle 11 rigidity step-down and thus can not obtain enough grinding forces.If described diameter is greater than 1.0mm, then the rigidity of bristle will be too high, and bristle will become frangible and easily rupture.
The bond material 12 be made up of the resin material of such as rubber, silicon rubber and Corvic and so on combines bristle 11 by covering bristle 11 around the periphery 11a of bristle 11.In the present embodiment, the tip portion of bristle 11 is shown as in FIG and is slightly exposed.This illustrates the vestige that the erection component (not shown) of the tip portion of constraint bristle 11 is set in the periphery 11a around bristle 11 is with the process of resin material covering bristle 11.After the bond material 12 of the periphery 11a (being painted on the periphery 11a of bristle 11) covering bristle 11 becomes dry and solidifies, remove erection component.Rope, rubber ring etc. can be used as erection construction material.
Even if the bond material formed thus 12 also can produce enough rigidity at the top end of bristle 11 when bristle 11 becomes longer.This is because bond material 12 can stop bristle along the Direction distortion of grinding in conjunction with bristle 11.By this way, abrasive brush 10 can produce high grinding force.In addition, according to the wearing and tearing on the top of bristle 11, the top of bristle 11 always can be exposed during grinding.This is because when bond material 12 is made up of resin material, and when the tip portion of bristle 11 is worn and torn in grinding process, bond material 12 little by little breaks according to the wearing and tearing on the top of bristle 11 or weares and teares.This makes the top of bristle 11 can have the rigidity of expectation, and grinding is performed when the top of bristle 11 is always exposed.
Bond material 12 can not be formed by means of only with resin material coating bristle 11, and by heating band or pipe and be attached to bristle 11 and formed.In addition, if can enough rigidity be obtained, then do not need to cover along the total length of bristle around the periphery 11a of bristle.Can freely determine bond material 12 length or should be combined the position of periphery 11a of bristle.
