Hybrid mode is a mechanically mixing.
Mechanically mixing adopts mixes continuously or intermittently mixes, and mixing process is carried out under normal pressure, and Heating temperature is 210 ℃～240 ℃.
The present invention compared with prior art has following advantage and effect:
(1) preparation technology is simple, and cost is lower;
(2) stronger reactive force between nanoparticle and the matrix in the matrix material need not nano particle is carried out finishing and realize that nanoparticle is uniformly dispersed and strong interfacial bond in macromolecule matrix;
(3) matrix material is white in color, and the dyeing behavior that component phase PTT is good is fit to dyeing;
(4) matrix material has higher tension, modulus such as curved, the use field of having widened material;
(5) matrix material has good creep-resistant property, lower water-intake rate, is suitable as the engineering materials of outdoor life-time service;
(6) be 0.5%～5%, over-all propertieies such as matrix material tension, curved intensity are increased substantially when the inorganic particulate mass content.
