Abstract

The invention relates to a PBT / ABS resin composition for automotive trim and a preparation method thereof. The PBT / ABS resin composition is composed of PBT, ABS, a low-smoke-density auxiliary agent, ahigh-oxygen-index auxiliary agent, a low-odor auxiliary agent and a processing auxiliary agent. According to the invention, PBT / ABS resin is endowed with better comprehensive performance by selectionof a plurality of auxiliary agents, so the PBT / ABS resin composition can be widely applied to automotive trim materials.

Description

technical field [0001] The invention belongs to the field of resin compositions, in particular to a PBT / ABS resin composition used for automobile interior decoration and a preparation method thereof. Background technique [0002] Due to its good chemical resistance and good thermal stability, PBT resin has been widely used in various fields, such as household appliances, electrical components, and automobile industry. However, as a semi-crystalline polymer, it has disadvantages such as poor dimensional stability and low-temperature impact performance. ABS resin has become one of the most widely used general-purpose plastics due to its excellent low-temperature impact performance and good dimensional stability. Combining the advantages and disadvantages of the two, it has become a trend to prepare alloy materials with excellent comprehensive properties. , in the automotive industry, as more and more OEMs have higher and higher requirements for flame retardancy of interior ma...
