Abstract
The invention provides a resin-based grinding wheel material and a preparation process thereof and belongs to the field of materials. The resin-based grinding wheel material is prepared from raw materials such as phenolic resin and epoxy resin, and multiple ingredients have a synergistic effect, so that the resin-based grinding wheel material has the advantages of good stability, high rigidity, excellent friction resistance and the like; all the ingredients have a synergistic effect, so that the resin-based grinding wheel material is not only good in rigidity, but also good in tenacity; a preparation method is simple and convenient in technological process and convenient in operation, thus improving the production efficiency.
Description
Technical field
The present invention relates to a kind of emery wheel material, particularly, relate to a kind of resin-based emery wheel material and preparation technology thereof.
Background technology
Resin-based emery wheel has the features such as sharp, wear-resisting, good processing accuracy because of it, and the share that occupation ratio is larger on superhard material grinding tool market is because the phenolic resins emery wheel life-span is lower, makes it use and is subject to certain limitation.Determine that the factor of resin wheel grinding performance mainly contains three: the interface cohesive force of adamantine performance, diamond and bonding agent and the performance of bonding agent.
Resin abrasive cutting wheel take resin as binding agent, and loose abrasive material bonding got up, be consolidated into the disc wheel of definite shape, it is mainly used in the cutting processing of the shapes such as round steel, band steel, steel pipe, angle steel, channel-section steel, rail.Along with developing rapidly of China's mechanical industry, unexpectedly striving of grinding materials and grinding tool market is more and more fierce, price war is inevitable development trend, therefore, most of manufacturer of China adopts the brown corundum abrasive that price is lower to manufacture resin abrasive cutting wheel, by the restriction of its performance, the cutting ability of this emery wheel can not meet the needs that mechanical industry develops rapidly.
If brown corundum abrasive calcination and inorganic or organic material are carried out surface treatment to improve its cutting ability, will inevitably complex manufacturing be caused like this, increase production cost.For this problem, according to the characteristic according to abrasive material, the black silicon carbide grain of a small amount of price lower than white fused alumina will be added to manufacture the abrasive cut-off wheel of resinoid bond mixed materials in Brown Alundum, be intended to the stock-removing efficiency and the durability that improve emery wheel, and don't obviously increase the production cost of product, become the technical problem of restriction resin sand extensive use.Resin-based emery wheel material of the present invention not only has good hardness, has again good adhesive property.Therefore there is good cutting force.
