Embodiment 1
[0027] Example 1 (to explore the relationship between the mixing mass ratio of phenolic resin and natural fiber rope and the polishing effect).
[0028] Recipe 1:
[0029]
[0030] Sample making
[0031] 1.1 Process route
[0032] 1.2.1 Glue on the hemp rope: Roll and coat a circle of glue on the processed sisal fiber rope (: 65% modified liquid phenolic resin solution, filler: 35%, glue solid content: 75-77% , the amount of glue is: 0.7-0.8g per gram of sisal fiber rope), and then baked at 70±2°C for 30min.
[0033] 1.2.2 Wrap the glued hemp rope on the mold according to the established route, then put it into the mold cavity, press and shape it, and bake it at 120°C for 4-6 hours (the flat grinding wheel is cured for 4 hours, and the circular grinding wheel is cured for 6 hours) , slowly lowered to room temperature and then out of the oven, unmoulded.
[0034] 1.3 The production pattern of this test is: flat polishing wheel: the outer diameter is 4 inches (101.6-103mm...
