Plasticizer and manufacturing method thereof
The invention discloses a plasticizer with high surface tension and a manufacturing method thereof, and the manufacturing method of the plasticizer comprises the following steps: mixing binary acid, dihydric alcohol and a catalyst to form a reaction mixture, and enabling the reaction mixture to react in a temperature range of 130-220 DEG C to form a semi-finished product. A blocking alcohol is added to the semi-finished product, and a reaction is carried out in a temperature range of 205 DEG C to 220 DEG C to form a crude plasticizer. The crude plasticizer is purified in a pressure range of 760 to 5 topples to obtain the plasticizer. The molar ratio of the dibasic acid to the dihydric alcohol to the terminated alcohol is 1: 0.6-0.9: 0.3-0.6. The dibasic acid comprises a first dibasic acid and a second dibasic acid, the second dibasic acid is adipic acid, the dibasic alcohol comprises diethylene glycol and 2-methyl-1, 3-propylene glycol, and the terminated alcohol comprises isooctyl alcohol, isodecyl alcohol or 2-propyl heptanol.
本发明公开一种高表面张力的可塑剂及其制造方法，可塑剂的制造方法包括：混合二元酸、二元醇以及催化剂，以形成一反应混合物，使反应混合物在130℃至220℃的温度范围中进行反应，以形成一半成品。于半成品中添加封端醇，在205℃至220℃的温度范围中反应，以形成一粗可塑剂。将粗可塑剂在760托耳至5托耳的压力范围中进行纯化，以获得可塑剂。二元酸：二元醇：封端醇的摩尔比例为1：0.6至0.9：0.3至0.6。二元酸包括一第一二元酸与一第二二元酸，第二二元酸是己二酸，二元醇包括二乙二醇及2‑甲基‑1,3‑丙二醇，封端醇包括异辛醇、异癸醇或2‑丙基庚醇。
