摘　　要：介绍了以甲苯2,4-二异氰酸酯(TDI)和环氧树脂作为改性剂对废弃聚苯乙烯泡沫塑料进行改性制备再生胶粘剂的方法。同时,就改性剂的选择、溶剂的选择、溶剂比的确定、改性剂的用量、两种改性剂的配比、改性反应时间的优选以及填料的加入量等诸多影响再生胶粘剂性能的因素进行了讨论,确定出了最佳的改性方案。所制得的这种再生胶粘剂质优价廉,固含量在40%左右,旋转粘度大于1 5Pa·s,常温拉伸剪切强度可达4 8MPa,游离甲醛、苯、甲苯、二甲苯等有害物质限量全部达到标准要求。可作为非结构胶粘剂用于粘结金属、玻璃、陶瓷、塑料、木材等。这是一条将废聚苯乙烯泡沫塑料变废为宝的较佳途径。Using recycling polystyrene foam as raw material,epoxy resin and tolylene diisocyanate as modifiers,an adhesive was prepared.Factors affected on properties of the adhesive,such as the quantity of the modified,solvent ratio, quantity of the filler,reaction temperature and time were discussed and determined.It had good properties and low cost.Its solid content was 40%,viscosity I=was 1.5Pa.s,shear strength reached 4.8MPa and no formaldehyde,benzene,tolylene and some other hazard.It could be used to bond metal,glass,ceramics,plastics,wood.
