Basalt fiber reinforced nylon 66 composite material and preparation method thereof

The invention belongs to the technical field of polymer processing, and discloses a basalt fiber reinforced nylon 66 composite material and a preparation method thereof, the basalt fiber reinforced nylon 66 composite material comprises nylon 66, maleic anhydride grafted hydrogenated styrene-butadiene-styrene elastomer, aminated basalt fiber and aminated silicon dioxide; the interface bonding force is improved through hydrogen-bond interaction formed by amino groups on the surfaces of the basalt fibers and the silicon dioxide and amino groups on a nylon 66 molecular chain; in addition, the compatibility is improved by reacting maleic anhydride of the hydrogenated styrene-butadiene-styrene elastomer with amino groups on the surface of silicon dioxide and amino groups at the molecular chain end of nylon 66. The basalt fiber and the silicon dioxide are used for reinforcing the nylon 66 by virtue of a hydrogen bond reinforced interface effect; the hydrogenated styrene-butadiene-styrene elastomer improves the tough
