Glass fiber reinforced nylon 66 and nylon 612 composite material and preparation method thereof

The invention relates to a glass fiber reinforced nylon 66 and nylon 612 composite material. The composite material is composed of the following raw materials by weight: 30-40 parts of nylon 66 resin, 20-40 parts of nylon 612 resin, 3-5 parts of a compatilizer, 20-40 parts of glass fiber, 0.5-1.0 part of an antioxidant, and 0.5-1.0 part of a lubricant. The glass fiber reinforced nylon 66 and nylon 612 composite material has the high rigidity effect of nylon 66 under normal temperature, also has high impact effect resistance, changes the defects of low temperature and easy brittleness, and the use temperature of the product is increased from the traditional 0DEG C-90DEG C to 60DEG C-180DEG C. 本发明属于种玻纤增强尼龙66、尼龙612复合材料，由下述重量份数的原料组成：尼龙66树脂30-40份、尼龙612树脂20-40份、相容剂3-5份、玻璃纤维20-40份、抗氧剂0.5-1.0份，润滑剂0.5-1.0份。本发明的玻纤增强尼龙66、尼龙612复合材料既具有常温下尼龙66的高刚性效果，也具备了-60℃温度下的高抗冲效果，改变了低温易脆的缺陷，使制品的使用温度从传统的0℃到90℃，提高到-60℃到180℃。
