Abstract

The invention provides an active filler pore-forming agent which contains aluminum hydroxide. According to the active filler pore-forming agent, the aluminum hydroxide is used as a pore-forming agent,a micropore tissue structure is formed in the resin grinding tool in the grinding process, grinding tool chip removal is facilitated, the problem of sliding caused by blockage of a grinding tool in the grinding process is solved, the abrasive edge forming effect of the resin grinding tool is effectively improved, the cutting force of the resin grinding tool is improved, and the stability of the cutting force of the resin grinding tool is ensured. The invention further provides the resin grinding tool comprising the active filler pore-forming agent, and specifically, the resin grinding tool comprises an abrasive, filler, a resin binder, a coupling agent and the active filler pore-forming agent. By applying the resin grinding tool, the cost is low, the resin grinding tool is god in stability of the cutting force, and the surface quality of a product can be effectively improved. The invention further discloses a manufacturing method of the resin grinding tool. The manufacturing method comprises the steps of mixing, forming and curing, the technology is simple, technological parameters are easy to control, and the obtained resin grinding tool is good in stability of the cutting force.

Description

technical field [0001] The invention relates to the technical field of cutting processing, in particular to an active filler pore-forming agent for cutting processing of glass, ceramics, etc., a resin abrasive tool containing the pore-forming agent and a manufacturing method thereof. Background technique [0002] At present, 3M Company of the United States and some other domestic manufacturers have successively developed grinding pads for rough grinding and fine grinding of glass planes, replacing the free grinding process of adding brown corundum to the cooling liquid. The old brown corundum grinding process is stable. Poor performance, large pollution, not environmentally friendly, low cutting efficiency, low yield rate of processed products, difficult post-processing and other problems. Using grinding pads to grind glass is more environmentally friendly and safe, with high processing efficiency and high yield rate of processed products. However, as the update speed of to...
