Embodiment 2
[0039] Present embodiment 2 is basically the same as embodiment 1, and its difference is:
[0040] In this embodiment 2, the composite cladding material includes the following components in parts by weight:
[0041] 100 parts of PVC powder;
[0042] 20 parts of TPU powder;
[0043] 60 parts of dioctyl phthalate;
[0044] 6 parts of epoxidized soybean oil;
[0045] 4 parts of calcium zinc composite heat stabilizer;
[0046] 10 parts of heavy calcium carbonate.
[0047] Performance testing was performed on the wear-resistant and cold-resistant modified PVC / TPU composite lightweight conveyor belt prepared in Example 2 above. The test results are shown in Table 1.
