摘要:
以聚异丁烯丁二酸酐(PIBSA)、聚乙二醇(PEG)200为原料合成了可作为乳化炸药乳化剂的聚异丁烯丁二酸聚乙二醇酯。用红外光谱对产物进行结构表征;采用单因素变量法对影响反应的一系列条件(温度、催化剂、原料组成比例等)进行探索,确定合成聚异丁烯丁二酸聚乙二醇酯的最佳工艺条件。结果表明,采用酯化温度为190 ℃、酯化时间6 h、酯化催化剂2%(质量分数)NaHCO3为合成条件时,能够得到优良的聚异丁烯丁二酸聚乙二醇酯。该乳化剂的乳化力优于Span80,制备出的乳胶基质的热稳定性优于以Span80和T152作为乳化剂制备的乳胶基质。
Abstract:
Polyisobutylene succinic anhydride (PIBSA) and polyethylene glycol (PEG) 200 were used as raw materials to synthesize polyisobutylene succinic polyethylene glycol ester which could be used as emulsifier in emulsion explosives. The structure of the product was characterized by infrared spectroscopy. Single factor variable method was used to examine a series of conditions that affect the reaction, such as temperature, catalyst, composition ratio of raw materials and so on. The optimal process conditions for synthesizing polyisobutylene succinic polyethylene glycol ester were determined. Results show that, when esterification temperature is 190 ℃, esterification time is 6 hours, and esterification catalyst is NaHCO3 with a mass fraction of 2%, polyisobutylene succinic polyethylene glycol1 ester in high quality can be obtained. The emulsifying power of this emulsifier is better than Span80, and the thermal stability of the prepared latex matrix is better than that of the latex matrix prepared with Span80 or T152.
