Abstract
The invention relates to a high-gloss and low-odor reinforced nylon composite material and the preparation method thereof. The composite material is characterized in that the composite material contains, by weight percentage, PA66 resin, PA6 resin, glass fiber, inorganic minerals, micro-beads, compatibilizer, antioxidant, lubricant, etc. The preparation method comprises the following steps: mixing the above materials in a high-speed mixer; discharging, and extruding and granulating the mixed material in a screw extruder. Compared with common fiber glass reinforced PA and mineral reinforced PA, the PA composite material prepared by the method has the advantages of high gloss, high strength, low odor, etc., and can be widely used for exterior trimming parts such as electric tool housing and motor housing and for interior parts.
Description
technical field [0001] The invention relates to a high-gloss, low-odor, reinforced nylon composite material and a preparation method thereof, which can not only be widely used in exterior decoration parts, such as electric tool casings, motor casings, etc., but also can be applied to some interior decoration parts, belonging to engineering plastics technology field. Background technique [0002] Nylon 6 and nylon 66 are widely used in various industries due to their excellent comprehensive properties. Glass fiber and mineral-filled modified nylon has good properties such as high strength, high heat resistance, high fatigue resistance, and low molding shrinkage, so it is widely used. Automobiles, machinery, home appliances, aviation and military components and other fields, and has developed into the world's largest engineering plastics. [0003] Nylon modified materials currently on the market are mainly glass fiber and mineral-filled modified composite materials. Although...
