Abstract

The invention discloses a high-wear-resistance high-weather-resistance polyamide composition as well as a preparation method and application thereof. The polyamide composition comprises the followingcomponents: polyamide resin, a toughening agent, methyl triallyl isocyanurate, glass fibers and an auxiliary agent. According to the invention, methyl triallyl isocyanurate is used as an assistant cross-linking agent to promote efficient intermolecular cross-linking of the polyamide material under irradiation, and the toughening agent and the glass fibers have a synergistic effect, so the comprehensive performance of the polyamide composition is improved. The polyamide composition has excellent wear resistance and weather resistance, and a polyamide product prepared through irradiation crosslinking treatment is suitable for being used as a wear-resistant part in the automobile industry or rail transit in a severe environment with large temperature difference.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyamide composition with high wear resistance and high weather resistance, a preparation method and application thereof. Background technique [0002] Polyamide materials are widely used in rail transit, electric tools and other industries. With the continuous development and progress of science and technology, the performance of materials in various industries has been continuously improved, especially for the rail transit industry. With the continuous advancement and deepening of new infrastructure, rail transit Construction involves a wider area and faces more complex climatic conditions, so the requirements for the comprehensive performance of materials are higher. Especially in some alpine or high-altitude areas, such as the Sichuan-Tibet line, the high altitude and large temperature difference between day and night put forward higher requirements for the wear ...
