[0044] Correspondingly, the embodiment of the present invention also provides a preparation method of the EVA coarse-cell composite foam material, comprising the following steps:
[0045] Step 1: Take quantitative isotactic polybutene-1 and melt it, and add mass content of 0.05%-0.2% graphene when the melting temperature of isotactic polybutene-1 is 140-170°C, so that both Graphene-modified isotactic polybutene-1 is obtained after mixing; the mixing time is 25-40 minutes, and the temperature is 150-180°C;
[0046] Step 2: taking each component in the material by weight fraction;
[0047] Step 3: Mix the other components weighed in step 2 except the crosslinking agent and foaming agent; the mixing time is 8-15 minutes, and the temperature is 100-110°C.
[0048] Step 4: Mix the material mixed in step 3 with the weighed crosslinking agent and foaming agent in step 2; the mixing time is 3-5 minutes, and the temperature is 110-120°C.
[0049] Step 5: The mixture obtained after kn...
