Problems solved by technology

[0002] The various polishing wheels currently produced have the following defects: ①Low polishing efficiency, such as hemp wheels (several layers of sisal are sewn together, and only the end face participates in grinding)
There is following shortcoming in the sisal fiber buffing wheel prepared with this kind of method: one, because the sisal fiber length used has only 4-12cm, thereby buffing wheel comes off easily in use sisal fiber, makes the service life of buffing wheel shortening; 2. Due to the limitation of needle punching density, it is impossible to ensure that any part of the polishing wheel can be tightly bonded, which will also affect the use effect of the polishing wheel
The polishing wheel produced by this method is molded and has no porous material, so the whole structure is very dense and has no gaps, which will easily cause the surface temperature of the grinding wheel to rise during the entire grinding process. The workpiece to be ground will also have a large surface temperature rise, which will cause stress concentration and may contaminate the surface of the workpiece to be ground

Embodiment 1

[0039] Example 1 (exploring the relationship between the volume ratio of hollow microspheres and natural fibers mixed with the polishing effect)

[0040] Recipe 1:

[0041]

[0042] 1 sample production

[0043]1.1 Mixing: according to the ratio of each style formula in formula 1, weigh the natural fibers in turn, (such as making a plane polishing wheel for flat polishing, use a fine number, and make a circumferential polishing wheel for circumferential polishing, then use a thick number), in the stirring state Then add the processed hollow microspheres to ensure uniform stirring; finally add the modified liquid phenolic resin in the stirring state and stir evenly. Throughout the mixing process, it is necessary to ensure that the mixing is uniform (no agglomeration or agglomeration).

[0044] 2.2 Pressing and solidification: According to the forming density of 0.6-0.7g / cm3, according to the volume of the polished wheel, calculate the weighing. Spread the weighed material ...

Abstract

The invention discloses a preparation method for a polishing wheel containing natural fibers and hollow microspheres. The preparation method includes the following steps: the natural fibers, the hollow microspheres and binder are mixed and uniformly stirred; the material is uniformly paved in a mould cavity; and the material is pressed to be shaped for two times by a hydraulic oil press.

Description

technical field [0001] The invention relates to a preparation method of a polishing wheel containing natural fibers and hollow microspheres, belonging to the field of abrasive tools. Background technique [0002] The various polishing wheels currently produced have the following defects: 1. The polishing efficiency is low, such as hemp wheels (several layers of sisal are sewn together, and only the end faces participate in grinding). Chinese patent CN1238254A discloses a sisal fiber polishing wheel, and discloses that its preparation method is: using a needle loom to make sisal short fibers into felt-like blanks, and then laminating 2-4 layers of sisal felt-like blanks , Sewn into a sisal fiber polishing wheel. There is following shortcoming in the sisal fiber buffing wheel prepared with this kind of method: one, because the sisal fiber length used has only 4-12cm, thereby buffing wheel comes off easily in use sisal fiber, makes the service life of buffing wheel 2. Due to ...
