Problems solved by technology

[0003] Existing nylon boards will be subject to friction and impact during use. Due to their poor wear resistance and impact resistance, deep damage will occur on the parts that are rubbed or impacted, which will reduce the service life of the nylon board. Due to the high temperature during use, the nylon board will undergo oxidation reaction, which will reduce its performance and greatly reduce the service life of the nylon board.

Abstract

The invention discloses a reinforced nylon plate based on silicon-aluminum-based hollow microspheres and a preparation process of the reinforced nylon plate. The nylon plate is prepared from the following raw materials in parts by weight: 100-120 parts of caprolactam, 3-5 parts of silicon-aluminum-based hollow microspheres, 3-5 parts of thermally stable filler and 1-3 parts of an antistatic agent.The silicon-aluminum-based hollow microspheres and the thermally stable filler are prepared in the preparation process, silicon ions and aluminum ions are grafted to a glass microsphere so that the friction resistance and the impact resistance of the nylon plate are greatly enhanced and the service life of the nylon plate is prolonged, the thermally stable filler can capture macromolecular free radicals in the nylon plates so that the macromolecular free radicals react with the thermally stable filler to terminate the free radicals and prevent the free radicals from continuing to react, so that a heat-resistant effect is achieved, heat-stable molecules cannot be separated from the body in a long-term use process of the nylon plate, the service life of the nylon plate is prolonged, the nylon plate is not easy to separate out, and environmental pollution is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of plate preparation, and in particular relates to a nylon plate reinforced with silicon-aluminum-based hollow microbeads and a preparation process thereof. Background technique [0002] Polyamide is collectively referred to as nylon (Nylon), and its English name is Polyamide (abbreviated as PA). It is named after the repeated amide group—[NHCO]—in the main chain of the molecule. , a class of basic resin with excellent comprehensive performance. [0003] Existing nylon boards will be subject to friction and impact during use. Due to their poor wear resistance and impact resistance, deep damage will occur on the parts that are rubbed or impacted, which will reduce the service life of the nylon board. Due to the high temperature during use, the nylon board will undergo oxidation reaction, which will reduce its performance and greatly reduce the service life of the nylon board.
