Nylon grinding block formula

Abstract

The invention belongs to the technical field of grinding materials, and provides a nylon grinding block formula. The nylon grinding block formula comprises the raw materials, by weight, 25-35% of epoxy resin, 10-20% of curing agents, 5-10 % of wetting agents, 1.2-1.7% of coupling agents, 3-7% of diamonds, 23-27.5% of silicon carbide, 7-9% of polyamide resin, 4-6% of zinc oxide and 1.5-2.5% of PVC resin sand. A nylon grinding block obtained through the nylon grinding block formula is high in hardness, good in tenacity, strong in grinding force, resistant to abrasion, good in heat resistance and long in service life, the machining cost of the unit area is lowered greatly, machining efficiency is improved, holding force is good, and grinding materials cannot drop easily in work.

Description

technical field [0001] The invention relates to a formula of nylon grinding blocks, belonging to the technical field of grinding materials. Background technique [0002] At present, the grinding block used for grinding and polishing bricks and stones in the building materials industry usually consists of 35% silicon carbide, 30% epoxy resin, 20% low molecular curing agent and 15% toluene. The grinding block prepared by using this formula has low hardness, weak grinding force, poor toughness, poor wear resistance and heat resistance. The grinding block wears a lot during work, and its service life is very short when used for processing. It can only grind and polish about 70 meters. When performing large-scale grinding and polishing, the grinding block needs to be replaced frequently. The production cost is high and the efficiency is low. At the same time, the polishing quality cannot be guaranteed, especially in the occasion of batch continuous operation. ;In the actual pro...

[0002] At present, the grinding block used for grinding and polishing bricks and stones in the building materials industry usually consists of 35% silicon carbide, 30% epoxy resin, 20% low molecular curing agent and 15% toluene. The grinding block prepared by using this formula has low hardness, weak grinding force, poor toughness, poor wear resistance and heat resistance. The grinding block wears a lot during work, and its service life is very short when used for processing. It can only grind and polish about 70 meters. When performing large-scale grinding and polishing, the grinding block needs to be replaced frequently. The production cost is high and the efficiency is low. At the same time, the polishing quality cannot be guaranteed, especially in the occasion of batch continuous operation. ;In the actual production of the above formula, the bonding force between the epoxy tree finger and silicon carbide is poor, and the holding force of the abrasive is not enough after the combination, and the abrasive is easy to fall off when the grinding block is working, which further shortens the service life of the grinding block and reduces the polishing efficiency; use Toluene is not environmentally friendly as an organic solvent for resins, and it is harmful to health. Long-term exposure can cause neurasthenia syndrome, hepatomegaly, dry skin, dermatitis, etc.
