Abstract

The invention belongs to the technical field of macromolecule commixing and molding processing and provides an extrusion-grade polycarbonate alloy material as well as a preparation method and application thereof. The extrusion-grade polycarbonate alloy material is prepared from the following components in percentage by weight: 30-90wt% of a polycarbonate resin, 5-60wt% of a rubber grafted polymer,1-20wt% of a polyolefin polymer, 0.1-10wt% of a compatilizer and 0-20wt% of a flame retardant, wherein the total weight of the components in percentage by mass is 100wt%. The preparation method comprises the following steps: (1) mixing the components; (2) putting the mixture of the step (1) into a double-screw extruder, melting and extruding materials, and carrying out bar drawing and pelletizing. Due to addition of the polyolefin polymer, the strength of a melt of the obtained polycarbonate alloy material can be remarkably improved while good physical and mechanical properties are ensured.

Description

technical field [0001] The invention belongs to the technical field of polymer blending and molding, and in particular relates to an extrusion-grade polycarbonate alloy material and its preparation method and application. Background technique [0002] Products such as wire and cable ducts and building panels are not suitable for injection molding due to their large thickness and long length, so they are generally prepared by extrusion. Therefore, the choice of extrusion process requires materials with high melt strength. Although the melt strength of the PC / ABS alloy is relatively high, it cannot fully meet the requirements of the extrusion process, and quality problems such as dimensional instability, uneven product surface, and bubbles often occur. [0003] With the improvement of people's safety awareness and the requirements of national laws and regulations, the performance requirements of materials in construction, electrical and electronic fields have gradually increa...
