摘要
Abstract
The crosslinking mechanism and the associated influence factors of sulphonated methyl phenolic resin(SMP) at high temperatures were investigated. And two control methods of high-temperature crosslinking for SMP were proposed. It is found that the crosslinking is promoted with higher pH value, bigger salinity, higher reaction temperature and longer time. The solid nuclear magnetic resonance (NMR) and infrared results indicate that the crosslinking is a dehydration condensation reaction between the hydroxymethyl and active hydrogen on the phenol ring, which forms methylene bridge. Hence, oxidant and sulfonating agent can be utilized to reduce the hydroxymethyl amount on the phenol ring. In this way, the crosslinking re-action of SMP at high temperature could be controlled, through which the stability of polysulfonate drilling fluid at high tem-perature is improved.关键词
