Nylon composite material and preparation method thereof

The invention relates to a nylon composite material which comprises the following components in parts by weight: 10-40 parts of short carbon chain nylon; 10-40 parts by weight of long carbon chain nylon; 10-40 parts by weight of glass fiber; 0.1-1 part by weight of a chain extender; 0.5 to 10 parts by weight of a compatilizer; 0.1-1 part by weight of an anti-hydrolysis agent; 0.1-1 part by weight of an anti-UV agent; 0.1-1 part by weight of an antioxidant; 0.1 to 0.3 part by weight of a coupling agent; and 0.1-0.3 part by weight of a lubricant. A product prepared from the glass fiber reinforced nylon composite material is excellent in comprehensive performance, especially excellent in hydrolysis resistance, free of floating fiber on the surface, good in appearance and relatively low in price, and can meet the requirements of development of the instrument industry such as the water meter industry. 本发明涉及一种尼龙复合材料，以重量份计，该材料包括：短碳链尼龙10-40重量份；长碳链尼龙10-40重量份；玻璃纤维10-40重量份；扩链剂0.1-1重量份；相容剂0.5-10重量份；抗水解剂0.1-1重量份；抗UV剂0.1-1
