Abstract

The invention discloses a PA6 buckle material for fixing a sound-absorbing module. The PA6 buckle material is prepared from, by weight, 50-85 parts of injection grade PA6 base material of which the viscosity ranges from 2.6 to 2.9, 15-50 parts of short-cut or continuous glass fibers, 0.1-0.8 part of antioxidant 1010 or 1098, 0.1-0.8 part of antioxidant 168, 0.1-1 part of UV agent 2020 or 770 or 4050, 0.1-1 part of UV agent 234 or 944 or 622, 1-3 parts of carbon black and 0.1-1 part of lubricating agent. According to the PA6 buckle material for fixing the sound-absorbing module, a nylon 6 based high polymer material blending modification technology is adopted, and by means of melting mixing and extruding methods such as glass fiber reinforcing, processing stabilizing and thermal-oxidation stabilizing, the PA6 buckle material for fixing the sound-absorbing module is obtained.

Description

technical field [0001] The invention belongs to the technical field of polymer material processing and application, and in particular relates to a PA6 buckle material for fixing a sound-absorbing module and a preparation method thereof. Background technique [0002] At present, while the construction of light rail and subway in China provides convenient transportation, it also brings about noise pollution. Laying sound-absorbing modules along the road is one of the effective ways to reduce noise pollution. With the continuous innovation and development and application of new polymer material technology, the frame and core layer of sound-absorbing module materials have been completely made of plastic materials, which not only reduces the weight of the module, is easy to construct and operate, but also solves the problem of metal materials. Poor corrosion resistance, affecting service life, increasing maintenance costs and other issues. However, the buckle material of the fi...
