A hydrolysis-resistant glass fiber reinforced high-insulation PBT composite material, a preparation method thereof and a processing device thereof

Abstract

This invention relates to a PBT engineering plastic resin composite material, specifically to a hydrolysis-resistant glass fiber reinforced high-insulation PBT composite material and its preparation method and processing equipment. Based on the existing PBT engineering plastic composite material raw material formulation, this invention adds a block polymer containing carbodiimide and carboxyl-based liquid nitrile rubber segments, along with a higher content of insulating agent. The added block polymer and insulating agent work synergistically with the original raw materials to prepare a PBT composite material with hydrolysis resistance, good mechanical properties, and good insulation. This invention effectively slows down the decay rate of tensile strength, flexural strength, and insulation performance of the hydrolysis-resistant glass fiber reinforced high-insulation PBT composite material, ensuring the effective performance of the hydrolysis-resistant glass fiber reinforced high-insulation PBT composite material products throughout their lifespan.
