摘要
Abstract
Dimethyl benzene sulfonic acid curing agent was prepared from xylene and strong sulfuric acid. The effect of water-carrying agent on the synthesis and the influence of inorganic acids and inorganic salts on the curing performance of moulding sand were investigated. The results show that toluene could carry most water produced during the synthesis and make synthesis react thoroughly. The prepared dimethyl benzene sulfonic acid curing agent has lower sulfur content of 7%. The partial substitution of sulfonic acid with inorganic acids and inorganic salts improved the curing performance of moulding sand; as a result, the tensile strength of the sand mold was over 1.8 Mpa.关键词
