Description

Technical Field

[0001] The invention relates to the technical field of improving the bonding force of abrasive surfaces, and in particular to an abrasive preparation method that utilizes recycled materials to improve the bonding force of abrasive surfaces. Background Art

[0002] At present, the precision grinding of hard and brittle materials basically uses resin bond or metal bond fine-grained diamond abrasives. Both types of abrasives are made by pressing and sintering. Diamond micro-powder abrasives prepared by pressing and sintering have many inherent disadvantages, because in the preparation process of this type of abrasive, when the diamond micro-powder abrasive and the binder powder are mechanically mixed, the diamond micro-powder is impossible to be dispersed. After pressing and sintering to make the abrasive, the distribution uniformity of the abrasive is very poor, which makes it easy to scratch the workpiece during use and affect its processing accuracy; and there is another type of abrasive that makes the abrasive bonded to the substrate to form the abrasive. Since the surface of the abrasive particles is generally smoother, the holding force of the binder on the diamond abrasive is not high, and the exposed height is small, which greatly reduces the processing efficiency and shortens the service life of the abrasive. Summary of the invention

[0003] The purpose of the present invention is to provide an abrasive preparation method for improving the surface bonding force of the abrasive by utilizing recycled materials in order to solve the above problems.

[0004] The present invention achieves the above-mentioned purpose through the following technical solutions: A method for preparing an abrasive by using recycled materials to improve the bonding force of the abrasive surface comprises the following steps: Step S1: collecting recycled materials; Step S2: bonding the recycled material to the abrasive using an adhesive; Step S3: baking the abrasive in a rotary kiln to solidify the recycled material on the surface of the abrasive; Step S4: bonding the finished abrasive to the abrasive tool for use.

[0005] Preferably: the recycled material in step S1 is 40 zirconium corundum powder.

[0006] Preferably, the specific steps of step S2 are: applying primer, gluing recycled materials, drying, re-gluing, and drying.

[0007] Preferably, the adhesive is a water-based glass adhesive.

[0008] Preferably: in step S4, the bonded abrasive tool should be placed for a day and a night before use, and the abrasive tool should be placed in a dry and ventilated place at ordinary times.

[0009] Preferably, the baking temperature in step S3 is 800-900°C.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The surface roughness of the abrasive is increased by bonding the recycled material to the abrasive surface, which improves the bonding firmness between the abrasive and the abrasive tool and greatly improves the durability of the abrasive; 2. The recycled material is 40 zirconium corundum powder, which ensures durability and improves the bonding strength between abrasives and abrasive tools without increasing material input costs too much. Recycling waste materials is practical and improves resource utilization. DETAILED DESCRIPTION
