摘　　要：聚合物的复合好坏主要取决于本体材料与填料之间的表面性质。因此,填料的表面改性就成为材料复合的关键。本工作用丁羟胶和甲苯二异氰酸酯在填充剂表面反应形成不可逆聚合层,即在填充剂表面包覆了一层聚氨酯高分子层。实验证明,拉伸强度最大害到30.4 MPa,抗冲击强度最大达到18.9 MPa,这有效地提高了复合材料的物理性能。The fastness of polymer composite is mainly depended on the surface properties between the body material and filler.Therefore,surface modification of packing is the key for fastness of material composite.In this paper,we used hydroxyl-terminated polybutadiene and toluene diisocyanate reacted in the filler surface to form irreversible aggregation layer.It coated with a layer of polyurethane polymer on the filler surface.Experiments showed that tensile strngth is maximum at 30.4 MPa,and the biggest impaet strength is 18.9 MPa.This effedively improved the physical properties of the composite material.
