specific Embodiment approach
[0086] A kind of preparation method steps of antibacterial non-slip plastic sheet cutting board is as follows:
[0087] A. Add inorganic fillers such as calcium carbonate, talcum powder, lithopone, and polyethylene low-molecular wax directly into the polypropylene polymer material resin 1, mix through a high-speed mixer 2, and put the mixture into the twin-screw extrusion after initial mixing Machine melt mixing 3;
[0088] The process is as follows: first pour the above-mentioned raw materials mixed in proportion into the mixing chamber of the high-speed mixer, first run at low speed for 30 seconds and then switch to high-speed rotation, when the temperature of the material rises to 70 degrees, the mixing is completed, and after the material is slightly cooled, it will be rotated under the action of the impeller Discharged from the discharge port;
[0089] After the temperature reaches the requirement, pour the mixture into the hopper of the twin-screw extruder, turn on the ...
