The invention relates to the technical field of polymer nylon materials, in particular to an environmentally friendly modified nylon material and a preparation method thereof, aiming to solve the problem of poor heat resistance of nylon materials in the prior art. The preparation method of the environmentally friendly modified nylon material includes the following steps: S1. Adding equal amounts of oxalic acid and 1,6-hexanediamine into a reaction kettle, heating to 180～200℃, adding tetrabutyl titanate after uniform stirring, raising the temperature to 250℃ under nitrogen protection, and reacting for 3～4 hours to obtain an initial nylon product; S2. Taking the initial nylon product, adding modified lignocellulose and graphene quantum dot-loaded nano boron nitride thereto, preheating at 70℃ for 1 hour, and mixing uniformly in a high-speed mixer to obtain a mixed material; S3. Feeding the mixed material into a twin-screw extruder, meanwhile adding zinc phytate, an antioxidant and a compatibilizer for extrusion granulation. During extrusion, a 30 wt% triethanolamine solution is added in an amount of 1.5% of the total mass of the mixed material to prepare the environmentally friendly modified nylon material.
