Problems solved by technology

[0006] Since PET polyester is a crystalline polymer and polycarbonate is an amorphous polymer, the simple blend system formed by the two is prone to phase separation, and the cohesive force of the two-phase interface is poor, making it difficult to improve the notched impact strength.

Abstract

Disclosed is a method for preparing a ball seat material for automobile guide ball pins, comprising the following steps: nano-scale alumina powder is modified by glycidyl methacrylate and a silane coupling agent; PET polyester and alumina particles are co- Mixed modification; polycarbonate and modified PET polyester melt blended ball seat material is injection molded to form a ball seat for automobile guide ball pins. The ball seat not only has high impact strength, but also has a high elongation at break; relevant technical indicators can fully meet the performance requirements of the ball seat used for automobile guide ball pins.

Description

Method of making ball seat material for automotive guide pins technical field The invention belongs to the field of automobile materials; relate to a kind of method of preparing the material used for automobile guide ball pin; More In particular, it relates to a method of making a ball seat material for an automotive ball guide pin. Background technique [0002] The guide ball pin is an important part of the automobile and is used to control the steering of the automobile. For a long time, the knot of the guide ball pin The structure is more complicated, and it needs to be rotated through the shape matching of the ball seat and the cylindrical shell, and the convenience of operation and assembly is poor. To a certain extent, the processing cost of automobiles has been increased. In addition, due to the complex structure, the guide ball pins are subject to long-term tension The wear is increased under the force and pressure load, the service life is short, and it is d...
