Abstract

The invention belongs to the technical field of alloy materials and discloses a polyethylene terephthalate (PET)/polycarbonate (PC) alloy material as well as a preparation method and application thereof. The PET/PC alloy material comprises the following components in parts by weight: 5-40 parts of PET, 50-85 parts of PC, 4-30 parts of a flexibilizer, 4-30 parts of a compatilizer, 0.1-4 parts of an ultraviolet-resistant agent and 0.1-2 parts of a stabilizer. The prepared PET/PC alloy material has excellent characteristics of vibration reduction, low-temperature impact resistance and fatigue resistance; the tensile strength is 75.6MPa, and the bending strength is 120.6MPa. The PET/PC alloy material is easily processed and molded, can be used for preparing high-performance whole steel rail concealed parts and is applied to urban rail transit.

Description

technical field [0001] The invention belongs to the technical field of alloy materials, in particular to a PET / PC alloy material and its preparation method and application. Background technique [0002] Urban rapid rail transit, including subways and light rails, is the backbone of public passenger transport in large cities. It is a popular, large-capacity, and independent urban passenger transport system with dedicated tracks. At the same time, it is also a large-scale basic project of the city, which occupies a very important position in the overall planning of urban construction. Rail transit is popular among citizens for its large capacity, fast speed, safety, reliability, and punctual and comfortable technical performance. Therefore, the construction of urban rail transit systems will become the development direction of public transportation in large cities in my country. The buckles, fastener pads and insulating buckles used in the existing urban rail transit as insul...
