The present invention is for providing a synthetic resin composition capable of effectively deodorizing amine malodor causing substances such as trimethyl amine. In a synthetic resin composition comprising an aqueous medium, a surfactant, and a polymer latex and a filler dispersed in the aqueous medium by the surfactant, a transitional metal supported silica gel having at least one selected from the group consisting of a transitional metal and a transitional metal compound supported by a silica gel and an activated carbon were used as the filler. Since the transitional metal or the transitional metal compound has an performs extremely well as a Lewis acid, it forms a complex with a Lewis base having an unpaired electron. That is, a malodor causing substance such as amines and ammonia having a nitrogen atom with an unpaired electron can be adsorbed efficiently.
本发明旨在提供一种合成树脂组合物,能够有效地去除胺类恶臭物质,如三甲胺。合成树脂组合物由水介质、表面活性剂、聚合物胶乳和由表面活性剂分散在水介质中的填料组成,在合成树脂组合物中,使用了过渡金属支撑的硅胶作为填料,该硅胶具有至少一种从过渡金属和过渡金属化合物组成的组中选出的过渡金属,并由硅胶和活性炭支撑。由于过渡金属或过渡金属化合物具有极佳的路易斯酸性能,因此会与具有未配对电子的路易斯碱形成络合物。也就是说,可以有效地吸附导致恶臭的物质,如胺和具有未配对电子的氮原子的氨。
