[0037] 在又另一个方面,该嵌段共聚物可以包括至少约3000g/mol的摩尔质量。 [0037] In yet another aspect, the block copolymer may comprise at least about 3000g / mol the molar mass. 具体地说,该摩尔质量可以是至少约3100g/mol、至少约3200g/mol、至少约3300g/mol、至少约3400g/mol、或至少约3500g/mol。 In particular, the molar mass may be at least about 3100g / mol, at least about 3200g / mol, at least about 3300g / mol, at least about 3400g / mol, or at least about 3500g / mol. 另一方面,该摩尔质量可以是至少约10000g/mol、至少约15000g/mol、至少约20000g/mol、至少约25000g/mol、至少约30000g/mol、至少约35000g/mol、至少约40000g/mol、至少约45000g/mol、或至少约50000g/mol。 On the other hand, the molar mass may be at least about 10000g / mol, at least about 15000g / mol, at least about 20000g / mol, at least about 25000g / mol, at least about 30000g / mol, at least about 35000g / mol, at least about 40000g / mol , at least about 45000g / mol, or at least about 50000g / mol. [0038] 在使用结合了这些增韧域到其中的研磨轮的过程中,这些增韧域可以作为减震器起作用。 [0038] In the combination of these processes wherein the toughening domains to the grinding wheel, the toughening domains can act as a shock absorber. 换言之,在使用结合了这些增韧域在其中的研磨轮的过程中,这些增韧域可以吸收能量。 In other words, the combination of the toughening domains during which the grinding wheel, the toughening domains can absorb energy. 减振或能量吸收可以归因于这些增韧域与粘合剂之间硬度上的差异。 Damping or energy absorption may be due to the difference in hardness between the adhesive and the toughening domains. [0039] 转到制造该粘结的研磨工具的方法,一种粘合剂粉末、一种两亲性嵌段共聚物粉末、以及一种磨料颗粒形成了一种共混的粉末。 [0039] Go to the bonded abrasive tool manufacturing method, a binder powder, one amphiphilic block copolymer powder, and a powder of abrasive particles form a blended. 该粘合剂粉末可以包括一种固体酚醛树脂或一种固体环氧树脂。 The adhesive powder may comprise a solid phenolic resin or a solid epoxy resin. 该两亲性嵌段共聚物粉末可以包括一种固体两亲性嵌段共聚物。 The amphiphilic block copolymer powder may comprise a solid amphiphilic block copolymer. 该固体两亲性嵌段共聚物可以包括一种粘合剂易混合的嵌段以及一种粘合剂不互混的嵌段。 The solid amphiphilic block copolymer may include a binder miscible block and a binder immiscible block. 在一个实施例中,该共混的粉末可以包括从约15wt%至约50wt%的粘合剂,从约lwt%至约15wt%的两亲性嵌段共聚物,以及从约50wt%至约80wt%的磨料颗粒。 In one embodiment, the blended powder may comprise from about 15wt% to about 50wt% of binder, the amphiphilic block copolymer is from about lwt% to about 15wt%, and from about 50wt% to about 80wt% abrasive particles. [0040] 该共混的粉末可以成形为一种粘结的磨料的形式。 [0040] This powder may be blended in the form of a bonded abrasive shape. 在一个实施例中,可以用该共混的粉末来填充一个模具空腔,并且可以在该模具内压缩该共混的粉末。 In one embodiment, the blended powders may be used to fill a die cavity and the powder blend may be compressed within the mold. 例如,可以通过冷压来压缩该共混的粉末,或可以在压制的过程中将热量添加到该粉末上,例如通过热压。 Heat in the process, for example, can be compressed by cold pressing the blended powders, or may be added to the pressed powder, for example by hot pressing. [0041] 在成形之后,可以将该基体材料成形的粉末固化从而形成一种研磨工具。 [0041] After the molding, the base material can be shaped so as to form a powder of the cured abrasive tool. 例如,可以通过将该共混的粉末加热到一个固化温度,例如至少约200° C,来将该基体材料固化。 For example, by heating the blended powder to a curing temperature, e.g., at least about 200 ° C, to cure the matrix material. 在一个实施例中,在保持在该模具空腔内时,可以将该基体材料基本上固化。 In one embodiment, when held in the mold cavity, the matrix material can be substantially cured. 在另一个实施例中,可以将该基体材料部分地固化到足以维持该研磨工具的形状的一个点(当从该空腔中移出时)。 In another embodiment, the matrix material may be partially cured to a point sufficient to maintain the shape of the abrasive tool (when removed from the cavity). 该研磨工具可以经受另外的固化以在从该模具空腔中移出之后基本上固化该基体材料。 The abrasive tool can be subjected to additional curing so as to substantially cure the matrix material after removal from the mold cavity. [0042] 在此所述的研磨工具可以具有使该研磨工具适合于改进的研磨和/或切削应用的某些特征。 [0042] The abrasive tools herein may have the abrasive tool is adapted to enable improved grinding / cutting or certain features and applications. 值得注意地,该粘结的研磨工具的断裂韧性得以改进。 Notably, the fracture toughness of the bonded abrasive tool is improved. 例如,可以通过测量引起该研磨工具中形成开裂所需要的力(指定SG1C),或通过测量特定的除去力(specificwork off force) (SpffOF)(它相应于将一个部件折断离开该粘结的研磨工具所需要的力)来确定断裂韧性。 For example, the force required to tear the abrasive tool is formed by causing measurement (designated SG1C), or by measuring the specific force is removed (specificwork off force) (SpffOF) (which corresponds to a part broken away of the bonded abrasive power tool required) to determine the fracture toughness. 与常规的磨料物品相比较,在此的实施例的磨料物品证明了改进的百分比增加的G1C以及百分比增加的SpWOF。 Compared with a conventional abrasive article, the abrasive article embodiment of this example demonstrate the increased percentage SpWOF G1C and improved percentage increase. 值得注意地,为了比较的目的,这些常规的磨料物品包括相同设计的磨料,具有包括树脂而不添加两亲性嵌段共聚物的基体材料。 Notably, for purposes of comparison, these conventional abrasive article includes abrasive same design, comprising a resin having a matrix material without the addition of the amphiphilic block copolymer. 根据经验性证据,该研磨工具可以具有超过一种类似的无两亲性嵌段共聚物的研磨工具至少约20%的百分比增加的匕(:。该百分比增加是基于公式((Gn-Gc)/Gc X 100%),其中Gn表示包括该两亲性嵌段共聚物的研磨工具的G1C,并且G。表示无该两亲性嵌段共聚物的研磨工具的G1C15在其他实施例中,该百分比增加G1C可以是至少约30%,例如至少约40%,例如至少约50%,甚至至少约60%。在一个实施例中,该百分比增加G1C可以是不大于约500%。[0043] 另外地,经验性证据还证明该研磨工具可以具有超过类似的无两亲性嵌段共聚物的研磨工具至少约10%的百分比增加的SpWOF。另外,百分比增加SpWOF可以是至少约15%,例如至少约20%。该百分比增加是基于公式((SN-S。)/S。X 100%),其中Sn表示具有该两亲性嵌段共聚物的研磨工具的SpWOF,并且S。表示无该两亲性嵌段共聚物的研磨工具的SpWOF。 The empirical evidence, the abrasive tool may have more than a similar non-amphiphilic block copolymer abrasive tool about 20% increase in the percentage of at least dagger (: This percentage increase is based on the equation ((Gn-Gc) / Gc X 100%), where Gn represents G1C abrasive tool comprising the amphiphilic block copolymer, and G. indicating no amphiphilic block copolymer abrasive tool G1C15 in other embodiments, the percent increase G1C may be at least about 30%, such as at least about 40%, such as at least about 50%, even at least about 60%. in one embodiment, the percent increase G1C may be not greater than about 500%. [0043] Further , the empirical evidence also demonstrated that the abrasive tool may have more than a similar non-amphiphilic block copolymer is at least about 10% of the abrasive tool of the percentage increase SpWOF. further, SpWOF percent increase can be at least about 15%, such as at least about 20% increase in the percentage is based on the equation ((SN-S.) / S.X 100%), wherein Sn represents an amphiphilic block copolymer abrasive tool SpWOF, and without the two represents S. SpWOF abrasive tool of amphiphilic block copolymer. 其他实施例中,该百分比增加SpWOF可以是不大于约500%。[0044] 液体两亲性嵌段共聚物,例如在美国公开物2009/0082486A1中所述的,被用于对用于多种应用中(例如层压)的环氧树脂进行增韧。这些应用依赖于包括聚(氧化乙烯)(PEO)和聚(氧化丁烯)(PBO)的一种两亲性嵌段共聚物。然而,使用液体树脂体系会引起产生粘结的磨料物品的问题,例如这些磨料颗粒在该液体中部分沉降。这可能导致磨料颗粒的不均匀分布以及不均匀的研磨性能。使用固体两亲性嵌段共聚物粉末为形成粘结的磨料物品提供了特别的优点。[0045] 另外,在某些实施例中,可以用于增加研磨轮应用中所使用的粘合剂的强度、或韧性的嵌段共聚物量值可以是这样一个小的量值,当与该粘合剂材料比较时,当将这样一种聚合物的液体形式与一种粘合剂粉末混合时,这个量值往往是极其难以得到基 In other embodiments, the percent increase SpWOF may be not greater than about 500%. [0044] Liquid amphiphilic block copolymers, for example, in the publication 2009 / 0082486A1 in the United States, are used for a variety of applications (e.g., laminated) to toughen epoxy resins. these include applications rely on a poly (ethylene oxide) (the PEO) and poly (butylene oxide) (a PBO) an amphiphilic block copolymer. However, using a liquid resin system can cause problems produced bonded abrasive article, the abrasive grains, for example, portions in the liquid settle. this can result in an uneven distribution of the grinding performance of abrasive particles and uneven. solid amphiphilic block the copolymer powder to provide the bonded abrasive article formed of particular advantage. [0045] Additionally, in certain embodiments, it may be used to increase the strength of the grinding wheel used in the application of adhesive, or toughness block such copolymer may be the magnitude of a small magnitude, when compared with the binder material when mixed form a liquid polymer with a binder powder, this is often extremely difficult to measure get base 上均匀分散的。然而,将这样一种嵌段共聚物的粉末形式进行混合可以允许在从该嵌段共聚物/粘合剂粉末混合物形成磨料物品之前将该嵌段共聚物均匀分散到该粘合剂粉末中。[0046] 实魁[0047] 形成了数种类型的磨料物品并且进行测试以将某些性能参数(包括临界能释放率(GlC)以及特定的除去力(SpWOF))进行比较。GlC是引起测试磨料物品开裂所需要的力的一个测量值,并且SpWOF是引起该测试磨料物品的一部分折断所需要的力一个测量值。[0048] 对比实例I是通过将一种酚醛树脂粉末压制到一个模具中并且将它加热到200° C的温度持续I小时而制备的一种基于酚醛树脂的配制品。 Uniformly dispersed. However, such a block copolymer in powder form are mixed may allow the abrasive article prior to forming the block copolymer / powder mixture from the adhesive block copolymer is uniformly dispersed into the adhesive the powder mixture.
