具体实施方式
本具体实施例仅仅是对本发明的解释，其并不是对本发明的限制，本领 域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造贡献的修改，但只要在本发明的权利要求范围内都受到专利法的保护。
本实施例涉及一种合成磨料，合成磨料包括以下各组分：聚丙烯、聚乙烯、研磨剂以及润滑剂；研磨剂为氧化铝、石英粉、火山灰中的至少一种。
氧化铝磨料硬度较高，与被抛光材料一般不发生化学反应，是一般钢铁试样常用的抛光磨料。石英砂是一种坚硬、耐磨、化学性能稳定的硅酸盐矿物，火山灰能够用于玻璃及眼镜研磨料，软金属及塑料抛光剂，显像管及荧光屏抛光剂，电镀前抛光金属(银、铜，家具、乐器)、清洗和摩擦木质、金属表面、石料。本实施例中将氧化铝等研磨剂与聚丙烯、聚乙烯相混合，在具有高硬度性能，高耐磨性和耐冲击性的同时，还具备合成树脂的微弹性，刚柔相济，能够在进行研磨的时候，减少对被加工工件表面的缓冲，避免对加工工件表面造成刮伤，能够适用于橡塑加工和大部分金属的研磨抛光。
在本实施例中，合成磨料的各组分重量百分比为：聚丙烯10-30％；聚乙烯20-50％；研磨剂30-70％；润滑剂5-15％。其中润滑剂为石蜡、动物蜡、植物蜡中的任意一种。因此该合成磨料能够在自身研磨过程中起到润滑、冷却的作用，同时有利于对待加工工件表面进行抛光，故在该合成磨料的使用中无需再次加入研磨剂，避免了研磨剂污染和清理问题。
在本实施例中，该合成磨料还包括松香，其中松香的重量百分比为3-10％。松香的黏性甚佳，尤其是压敏性、快黏性、低温黏性很好、松香具有增黏、乳化、软化、防潮、防腐、绝缘等优良性能，能够促使该合成磨料快速成型，提高该合成磨料的耐化学腐蚀性能，提高使用寿命。
需要说明的是，本合成磨料中的全部组分均无需耗费木材利于环保，并且由于研磨剂和聚丙烯、聚乙烯的熔点差距较大，因此在多次使用过后可将 该合成磨料回收加工再利用，进而有利于节约生产成本，促进可持续发展。
在本实施例中，各组分重量百分比优选为：聚丙烯15％，聚乙烯25％，研磨剂42％，润滑剂15％，松香3％，从而得到具有高耐磨性、高弹性且化学性能稳定，使用寿命长的合成磨料。润滑剂在研磨过程中能够逐渐软化起到润滑、冷却的作用，同时有利于对待加工工件表面进行抛光，从而得到较好的研磨和抛光效果。
基于以上合成磨料，本实施例还涉及一种合成磨料的制备方法，所述方法包括：
S1:配料，按下述重量比称重各种原材料：聚丙烯10-30％；聚乙烯20-50％；研磨剂30-70％；润滑剂5-15％、松香3-10％；
S2:混料，将S1中称取的原料加入搅拌桶，充分搅拌均匀；
S3:加热，放入挤出机中加热，加热温度为130-300℃；
S4:挤出成型，通过切割或造粒制出所需形态。
本发明的工作原理大致如下述：本发明通过采用聚乙烯、聚丙烯以及研磨剂相混合，研磨剂由氧化铝、石英粉、火山灰中的至少一种构成，从而具有高硬度性能，聚乙烯和聚丙烯具有良好的高耐磨性和耐冲击性，同时还具备植物磨料的弹性，刚柔相济，耐磨性好，并且通过直接在磨料中添加润滑剂，能够在研磨过程中起到润滑、冷却的作用，因此无需再次加入研磨剂，避免了研磨剂污染和清理问题，能够适用于橡塑加工和大部分金属的研磨，无需耗费木材利于环保，多次使用过后废料可回收加工再利用，有利于节约生产成本。并且该合成磨料的制备方法，原料易得、混合方便，具有优良的化学稳定性，优异的耐化学腐蚀，溶剂浸泡性。且制备过程中能够快速成型，易制成各种形状，容易进行二次加工，可满足用户对形状尺寸的要求。
