一种新型沙土治理剂的研制
Preparation of a Novel Sand Control Agent
摘要
Abstract
In order to develop a sand control polyurethane prepolymer with longer curing time,PPG,HTPB and MDI were used as raw materials,influences of the ingredient ratio,reaction temperature,reaction time on the product performances were investigated. The following conditions suitable for preparing qualified polyurethane prepolymer were obtained: the molar ratio of PPG and HTPB:1 : 2,the molar ratio of NCO and OH:3 : 7,reaction temperature: 80℃ , reaction time:50 to 60 min. The preparation process of a new type sand control agent was thus established.关键词
