[0027] A preparation method of LVT floor, comprising the above-mentioned LVT floor, comprises the following steps in turn:
[0028] Step 1: Stir and mix the raw materials for the first time: put PVC resin powder, carbon black, and stabilizer into the mixer in proportion to mix, and add plasticizer to the mixer during the mixing process, and the mixing time is 10 minutes;
[0029] Step 2: Stir and mix the raw materials for the second time: add stone powder to the mixture stirred in Step 1 and stir for 30 minutes;
[0030] Step 3: Internal mixing: transport the mixture mixed in step 2 to the internal mixer for heating and internal mixing to form through the conveyor belt. The internal mixing time is 4 minutes, and the internal mixing temperature is 165°C to 175°C;
[0031] Step 4: Cutting: Cool the raw materials formed in Step 3 and cut them into block-shaped bottom and middle materials;
[0032] Step 5: Hot pressing: Put the bottom material and middle material cut in step 4 in...
