The invention relates to an identification method of an abrasion-resistant plastic particle. The method comprises the following steps: taking a plastic particle in a high-precision weighing tool and weighing the plastic particle to obtain the mass of the plastic particle; viewing exterior color, transparency, texture and particle size of the plastic particle to be identified through naked eyes and/or magnifying lenses; sensing strength and toughness of the plastic particle by using manners of pulling via hands, pressing and striking; respectively putting the plastic particle in a water solution, an industrial alcohol solution and an industrial salt water solution, and judging the density of the plastic particle by observing the suspension degree of the plastic particle; clamping the plastic particle over open fire by using a clamping tool and calcining the plastic particle for 1-5 seconds, then taking the combusted plastic particle away from the open fire, and judging elements in the plastic particle by observing the sustained combustion time and the combustion color of the plastic particle and combining the quality of the plastic particle.
