Embodiment 1
[0031] Add 15kg of toluene, 20kg of dimethylformamide, and 7kg of methyl ethyl ketone into a large tank and add 3kg of cellulose acetate butyrate under stirring. After the addition, control the stirring speed to 800-1500 rpm, and control the temperature not to exceed At 50°C, fully dissolve cellulose acetate butyrate to obtain a transparent liquid. After the dissolution is complete, add 8 kg of stress-changing wax powder, disperse evenly, and filter it into another large tank with 200 mesh.
[0032] Then add 0.5kg of sodium lauryl sulfate dispersant, 0.5kg of polyether siloxane leveling agent, and 37kg of modified aliphatic polyurethane resin in turn, then stir, and add 2kg of fumed silica thickening powder at a low speed And 7kg of yellow nylon fluff powder, after adding all the materials, increase the rotation speed at a stirring speed of 800-1000 rpm, and pay attention to controlling the temperature not to exceed 50°C for high-speed dispersion for about 20 minutes.

Embodiment 2
[0035] Add 10kg of toluene, 25kg of dimethylformamide, and 7.5kg of methyl ethyl ketone into a large tank and add 2.5kg of cellulose acetate butyrate under stirring. After the addition, control the stirring speed to 800-1500 rpm and control the temperature. Not exceeding 50°C, fully dissolve the cellulose acetate butyrate to obtain a transparent liquid, add 8 kg of stress-changing wax powder after the dissolution is complete, disperse evenly, and filter it into another large tank with 200 mesh.
[0036] Then add 0.5kg of sodium lauryl sulfate dispersant, 0.5kg of polyether siloxane leveling agent, and 37.5kg of modified aliphatic polyurethane resin in turn, then stir, and add 1.5kg of fumed silica at a low speed. For the thick powder and 7kg of yellow nylon fluff powder, after adding all the materials, increase the rotation speed at a stirring speed of 800-1000 rpm, and pay attention to controlling the temperature not to exceed 50°C for high-speed dispersion for about 20 minute...
Embodiment 3
[0039] Add 10kg of toluene, 25kg of dimethylformamide, and 7kg of methyl ethyl ketone into a large tank and add 2kg of cellulose acetate butyrate under stirring. After the addition, control the stirring speed to 800-1500 rpm, and control the temperature not to exceed At 50°C, fully dissolve cellulose acetate butyrate to obtain a transparent liquid. After the dissolution is complete, add 8 kg of stress-changing wax powder, disperse evenly, and filter it into another large tank with 200 mesh.
[0040] Then add 0.5kg of sodium lauryl sulfate dispersant, 0.5kg of polyether siloxane leveling agent, and 40kg of modified aliphatic polyurethane resin in turn, then stir, and add 1kg of fumed silica thickening powder at a low speed And 6kg of yellow nylon fluff powder, after adding all the materials, increase the rotation speed at a stirring speed of 800-1000 rpm, and pay attention to controlling the temperature not to exceed 50°C for high-speed dispersion for about 20 minutes.
