[0035] see figure 1 , the preparation method of above-mentioned deformation material, comprises the following steps:
[0036] S110. Stir 20-40 parts of SEEPS and 10-25 parts of white oil until the SEEPS completely absorbs the white oil.
[0037] In one embodiment, the stirring is carried out in a high-speed mixer, the stirring speed of the high-speed mixer is 250r / min-400r / min, and the stirring time is 10min-15min.
[0038] S120. Add 15-35 parts of petroleum resin and 0.2-0.3 parts of antioxidant to the SEEPS that has completely absorbed the white oil and continue stirring.
[0039] In one embodiment, the stirring is carried out in a high-speed mixer, the stirring rate of the high-speed mixer is 250r / min-400r / min, and the stirring time is 3min-5min.
[0040] S130, adding 10-30 parts of plasticizer and continuing to stir to obtain a premix.
[0041] In one embodiment, the stirring is carried out in a high-speed mixer, the stirring rate of the high-speed mixer is 250r / min-400...
Embodiment 1
[0047] Stir 20 parts of SEEPS and 10 parts of paraffin oil in a high-speed mixer for 10 minutes until SEEPS completely absorbs the paraffin oil. The rotational speed of the mixer is 400r / min. Add 35 parts of carbon-5 hydrogenated petroleum resin and 0.2 part of (3,5-di-tert-butyl-4-hydroxyphenyl) propionate octadecanoate to the SEEPS that has completely absorbed paraffin oil and continue stirring for 3 minutes . Add 10 parts of diisononyl cyclohexane 1,2-dicarboxylate and continue to stir to obtain a premixture, and the stirring time is 3 minutes. The premix is plasticized, extruded and granulated in a twin-screw extruder to obtain a deformed material. The temperature of the twin-screw extruder is 60° C., and the rotation speed is 700 r / min.
Embodiment 2
[0049]Stir 20 parts of SEEPS and 25 parts of paraffin oil in a high-speed mixer for 12 minutes until SEEPS completely absorbs the paraffin oil. The rotational speed of the mixer is 250r / min. Add 15 parts of carbon-9 hydrogenated petroleum resin, 5 parts of PE wax and 0.3 part of tris(2,4-di-tert-butylphenyl)phosphite to the SEEPS that has completely absorbed paraffin oil and continue stirring for 5 minutes. Then add 20 parts of diisononyl phthalate and continue to stir to obtain a premix, and the stirring time is 5 minutes. The premix is plasticized, extruded and granulated in a twin-screw extruder to obtain a deformed material. The temperature of the twin-screw extruder is 80° C., and the rotation speed is 500 r / min.
