| titleOfInvention | LAS-series microcrystalline glass abrasive binding agent formula, preparation method and application thereof |
| abstract | The invention discloses a formula of a bonding agent for LAS microcrystalline glass abrasive, a preparation method and application thereof, belonging to the field of microcrystalline glass abrasive tools. The LAS microcrystalline glass abrasive bond is prepared from the following components in percentage by mass: 4-9% of Li 2 O，14～20％Al 2 O 3 ，48～58％SiO 2 ，8～16％B 2 O 3 ，0.8～2.2％Na 2 O，0.8～1.2％K 2 O，1～4.5％MgO，1～3％ZnO，0.5～1.5％BaO，3.5～4.5％TiO 2 . The melting temperature is 1200-1300 ℃, the sintering temperature is 600-780 ℃, the thermal expansion coefficient is small, the adjustable characteristic is realized, the wettability is good, the grinding tool is suitable for preparing grinding tools from abrasive materials such as white corundum, green silicon carbide, artificial diamond and the like, the density of the grinding tool is moderate, the water absorption rate is low, the apparent porosity and the flexural strength are high, a good chip containing space is provided, the holding force on the abrasive materials is good, and the grinding tool is not easy to fall off in the processing process. |
