Abstract

The invention relates to the technical field of PC composite materials, in particular to a preparation method of a low-temperature-resistant impact-resistant PC composite material, which comprises the following steps: step 1, preliminary mixing; step 2, high-temperature melting of mixed materials; step 3, preliminary cooling of liquid; step 4, extrusion of soft materials into rods; step 5, complete hardening of the materials; step 6, cutting of PC rods; step 7, detection of the PC materials; and step 8, packaging and storing of qualified products. According to the preparation method of the PC composite material, the efficiency is higher, the PC composite material is excellent in texture and very suitable for industrial automatic production, toner is gradually injected in a liquid state, the prepared PC composite material has good color appearance, efficient and rapid cooling is achieved through a temperature control mechanism in the machining process, and the high toughness of the PC composite material is ensured.

Description

technical field [0001] The invention relates to the technical field of PC composite materials, in particular to a method for preparing a low-temperature-resistant and impact-resistant PC composite material. Background technique [0002] Polycarbonate in the prior art is a high molecular polymer containing carbonate groups in the molecular chain, and can be divided into aliphatic, aromatic, aliphatic-aromatic and other types according to the structure of the ester group. Among them, due to the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates, which limit their application in engineering plastics, only aromatic polycarbonates have been industrialized. Due to the special structure of polycarbonate, it has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. [0003] With its unique characteristics of high light transmittance, high impact resistance, dimensional stability and easy processing and mo...
