Beschreibung
Zusammenfassung:	The invention discloses hardened polyethylene foam and a preparation method thereof, the composition comprises, by weight, 100 parts of irradiated PE, 3-10 parts of AC foaming agent, 0.1-1 part of foaming promoter, 0.1-1 part of lubricant, 0.1-2 parts of antioxidant and 5-25 parts of filler, the irradiated PE is a, b or a, b and c composition, the a. Irradiated HDPE is formed by irradiating HDPE, the b. LDPE and the c. Irradiated LDPE are formed by irradiating LDPE, and the a is 30-60wt% of the irradiated PE. The preparation method of the polyethylene foam comprises the following steps: S1, mixing the composition, and granulating to prepare particles; s2, preparing an extruded sheet after granulation; s3, carrying out irradiation crosslinking on the extruded sheet; and S4, the irradiated sheet is subjected to pre-foaming, foaming, embossing and rolling, and the hardened crosslinked polyethylene foam is obtained. According to the invention, irradiation HDPE particles and LDPE are blended to solve the problem o
