The invention discloses an easily melted foamed polyethylene bead with strong temperature tolerance and a preparation method thereof. Low density polyethylene with a Vicat softening point of 90 to 105DEG C and high density polyethylene are compounded, at the same time, an inorganic compounding foaming aid is adopted, and through the synergistic effect generated by three components, goals of easily melting and high temperature tolerance are realized. Through the cooperation of formula and technology, the size of inner pores of primarily foamed EPE beads is controlled in a range of 200 to 230 [mu]m, after foaming, no thermal insulation device is needed, and a step of introducing steam with a certain air pressure into a pipe for delivering polypropylene resin particles is not needed either.The moulding steam pressure is obviously reduced, the melting stability between particles is excellent, and the curing degree is 95% or more. Because the inner pores in the beads are increased, and the pore uniformity is increased, the polyethylene bead can tolerate a certain moulding temperature, the stiffness of pores in the surface of a moulded product is improved, and the beauty of the surfaceof a EPE bead moulded product is obviously improved.
