Abstract

The invention relates to a nylon corrugated pipe composite material for a vehicle. Through cooperative use of PA6, a flame retardant, a stabilizer, a flexibilizer, a lubricant, an odor adsorbent, a melting conditioning agent and color masterbatch, the weight is reasonably selected, and during use in the middle and later period, due to the synergistic effect of the heat stabilizer and a light agingagent, the anti-thermal-oxidation-aging performance and light-oxidation-aging prevention performance of the material are obviously superior to that of a traditional composition. The odor of the nyloncorrugated pipe composite material for the vehicle is lower than 3.0, the material is superior to existing congeneric products, has high-temperature and low-temperature resistance and flame retardance and is low in odor and suitable for extrusion processing, and the application range of corrugated pipe products in the vehicle industry is greatly enlarged. In addition, the preparation method of the nylon corrugated pipe composite material for the vehicle is easy to operate, and the material is low in cost and extremely suitable for industrialization mass production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a nylon bellows composite material for vehicles and a preparation method thereof. Background technique [0002] Nylon 6 (PA6) resin is rich in sources, and PA6 plastic has excellent properties such as good rigidity, high strength, corrosion resistance, good electrical insulation, and adjustable softness and hardness, so it is widely used. How to overcome the decomposition and aging of materials caused by heat, light and oxygen is the key to the use of PA6 in some high-temperature and high-humidity environments. The bellows material is formed by extrusion, and the PA6 raw material has a high melting index, which is not conducive to extrusion, and cannot meet the flame retardant requirements, heat aging resistance, and low temperature resistance requirements of the bellows. [0003] CN 106810856A discloses a corrugated material, but it can only meet the aging requirement...
