一种三元共聚物弹性颗粒调剖材料及其制备方法
摘要：
本发明公开了一种三元共聚物弹性颗粒调剖材料及其制备方法，其中三元共聚物结构为TPV/TPES/SEBS‑g‑MAH，该颗粒是以TPV/TPES为原料，以SEBS‑g‑MAH接枝改性，在175~185℃温度下密炼5‑15min，155~165℃温度5‑10MPa压力下热压5~20min，自然冷却后，以水冷方式旋切造粒，得到白色圆柱形或椭圆形弹性颗粒，粒径为2~10mm，密度为0.9~1.1g/cm3，邵氏硬度为0~20°，模量为0.5~5MPa，断裂伸长率为100~1000%。本发明制得的弹性颗粒调剖材料具有韧性好、变形能力强、不易破碎断裂、化学稳定性好的特点，施工方便，可提高调剖有效期。
摘要（英）：

The invention discloses a terpolymer elastic granular profile control material and a preparation method thereof. A terpolymer is of a TPV/TPES/SEBS-g-MAH structure. TPV/TPES serve as raw materials and are subjected to graft modification with SEBS-g-MAH, mixing is carried out for 5-15 min at the temperature of 175-185 DEG C, hot pressing is carried out for 5-20 min at the temperature of 155-165 DEG C and the pressure of 5-10 MPa, rotary-cutting granulation is carried out in a water cooling mode after natural cooling, and cylindrical or oval white elastic granules are obtained. The granule size is 2-10 mm, the density is 0.9-1.1 g/cm<3>, the shore hardness is 0-20 degrees, the modulus is 0.5-5 MPa, and the elongation at break is 100-1000%. The obtained elastic granular profile control material has the advantages of being good in tenacity, strong in deformability, not likely to break or facture and good in chemical stability, construction is convenient, and the useful life of profile control can be prolonged.
