Abstract
The invention provides a fiber polishing wheel. The fiber polishing wheel is formed by soaking fiber felt with binding agent adhered thereon in a mixed material. The mixed material comprises resin, a grinding material, polishing powder, emulsifying agent and microcrystalline wax. The fiber felt is obtained by fiber needling. A production method of the fiber polishing wheel includes needling fibers by needles; applying the binding agent to the fiber felt subjected to needling to obtain the fiber felt with the binding agent; mixing the resin with the grinding material, the polishing powder, the emulsifying agent and the microcrystalline wax to obtain the mixed material; soaking the fiber felt with the binding agent in the mixed material to obtain the fiber polishing wheel. The fiber polishing wheel wears slowly during use, and grinding capability is improved greatly.

Mixed material obtained above is poured in the equipment of compregnate shown in Fig. 2 and carries out compregnate, wherein top roller diameter be 300mm, the angle part that formed of the length rubber roll that is 1500mm, rubber roll two ends baffle plate blocks, and prevents mixed liquor from overflowing.Then round shape bamboo fiber felt obtained above is carried out compregnate in mixed liquor, the mass ratio of bamboo fiber felt and mixed liquor is 1: 4.In compregnate process, initiatively rubber roll turns to the inside, drive driven rubber roll also to turn to the inside, so just fibrofelt after mixed liquor along with the turning handle black corundum of rubber roll, aluminium oxide, non-ionic surface active agent, PP microwax powder and resin are evenly distributed on fibrofelt.
The fibrofelt that 10 layers contain black corundum, aluminium oxide, non-ionic surface active agent, PP microwax powder and resin is superimposed, then the stereotype plate of cooler is put into, surrounding is put into the sizing side's bar being of a size of 2.5cm and is carried out colding pressing pre-setting, obtains superimposed shaping semi-finished product.The time of cooling and shaping is 40 minutes, and pressure is 3mpa.
Be placed in the stereotype plate of hot press by the superimposed shaping semi-finished product obtained, surrounding is put into the sizing side's bar being of a size of 2.5cm and is carried out hot-forming.Hot-forming temperature is 150 DEG C, and pressure is 4mpa, and the time is 40 minutes.To be cooledly to unclamp to when 60 DEG C, obtain shaping flaxen fiber wheel.
Be the hole of 50mm, then deburring at fiber wheel centre drill diameter, obtain the fiber polishing wheel C of finished product.
Existing fiber polishing wheel on the fiber polishing wheel A that the present invention obtains above-described embodiment, fiber polishing wheel B, fiber polishing wheel C and market has done the test of grinding capacity aspect, method of testing and test result as follows:
Test condition: rotating speed is 2800rpm, power is 3KW, and pressure is 2kg.
Table 1 products and marketing existing product of the present invention grinding capacity contrast table
| Title | The grinding time | Stock removal |
| Product A of the present invention | 1 minute | 7.3g |
| Product B of the present invention | 1 minute | 7.5g |
| Products C of the present invention | 1 minute | 7.1g |
| Existing products in markets | 1 minute | 5.1g |
As can be seen from Table 1, the grinding capacity of fiber polishing wheel provided by the invention improves 39% compared with fiber polishing wheel existing on market, is far superior to existing product.
The in use loss of fiber polishing wheel provided by the invention polishing wheel more of the prior art is slow, and grinding capacity improves greatly.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
