The invention relates to the field of preparation of high polymer materials, in particular to a flexible irradiation crosslinking polyethylene foam material with high tensile strength and a preparation method thereof. According to the method, an elastic grafted polyion brush functional component is compounded with low-density polyethylene, so that the flexibility and tensile strength of the polyethylene foam can be effectively improved, and the polyethylene foam material with flexibility, high tensile strength and no corona gluing is obtained. The method disclosed by the invention has the following advantages: (1) the product is good in flexibility and high in tensile strength, and when the apparent density is lower than 0.1 g / cm < 3 > and the thickness is 1mm, the elastic modulus is below 0.8 MPa, the tensile strength is more than 1.6 MPa, and the elongation is more than 250%; (2) the cohesiveness of the product is high, the surface tension can reach 39 mN / m or above, the requirement of a gluing process is met, and the surface tension can be maintained for 6 months or above; and (3) the obtained product has wide application in the fields of precision mechanical shock absorption, electronic equipment, electronic screen protection and the like.
