Abstract

The invention discloses a thermoplastic resin composition with a low density characteristic and a preparation method and an application thereof, composite hollow microspheres wrapped by a water-based polymer have low density performance and good shear resistance and pressure resistance, the material is applied to preparation of the thermoplastic resin composition, the condition that the low-density inorganic hollow microspheres are extremely easy to damage in screw extrusion blending processing can be obviously improved, so that the prepared thermoplastic resin composition has the characteristic of low density.

Description

technical field [0001] The invention relates to the technical field of polymer materials, and more specifically, relates to a thermoplastic resin composition with low density characteristics, a preparation method and application thereof. Background technique [0002] With the highly developed productivity in the world today, and people's increasing awareness of environmental protection. Energy saving and emission reduction has been the common pursuit of people, which has also aroused attention to the topic of lightweight materials. For many vehicles, it is particularly meaningful to achieve lightweight, because reducing weight can not only effectively reduce the energy consumption of the vehicle, but also effectively improve the mobility of the vehicle under the same driving force. It is especially obvious on high-end vehicles such as sports cars and sports cars. Since the birth of polymer materials, they have played an increasingly important role in our world. Among them,...
