Abstract

The invention relates to a coated abrasive tool and a preparation method and application method thereof. The coated abrasive tool comprises a base material and an abrasive material layer. The abrasivematerial layer comprises a primer layer, an abrasive material implanted into the primer layer and a composite glue layer coating the abrasive material and the primer layer. Abrasive particles with the sand implanting angle alpha being larger than or equal to 30 degrees and smaller than 90 degrees in the abrasive material implanted into the primer layer are 20%-50% of all abrasive particles. According to the coated abrasive tool, the sand implanting angle of part of abrasive material is adjusted, the contact angle of the abrasive material and a machined workpiece is optimized during grinding,and tests prove that the grinding efficiency of a product of the coated abrasive tool can be effectively improved by adjusting the sand implanting angle of the abrasive material.

Description

technical field [0001] The invention belongs to the field of coated abrasives, and in particular relates to a coated abrasive and its preparation method and use method. Background technique [0002] Coated abrasives use adhesives to adhere abrasives to flexible substrates, also known as flexible abrasives. Sand planting is an important link in the preparation of coated abrasives. Traditional sand planting methods include gravity sand planting and electrostatic sand planting. Gravity sand planting is to plant sand through the gravity of the abrasive itself, and the sand planting direction of the abrasive is random. At present, the application of electrostatic sand planting is more and more extensive, which can obtain a more consistent abrasive arrangement effect, and its working process (such as figure 1 As shown) is to use the high-voltage electrostatic field provided by the external power supply 1. When the abrasive 2 travels in the direction of the arrow, it relies on th...
