  The foam sheet of the present invention is biodegradable, can be recycled, has good processability, is lightweight, exhibits excellent appearance, has practically satisfactory heat resistance and is more acceptable to the environment. There is provided a crosslinked biodegradable resin continuous foam sheet comprising biodegradable resin, and has an expansion rate of about 1.5 to about 50 and a gel fraction of about 3% or more. There is further provided a method for producing the foam sheet comprising the steps of: (1) preparing a sheet from a resin composition comprising a biodegradable resin, a thermal decomposable blowing agent and a crosslinking promoter; (2) irradiating the resulting sheet with an ionizing radiation to crosslink the resin composition; and (3) subjecting the crosslinked sheet to heat treatment to continuously prepare a crosslinked foam sheet. Thus, the foam sheet of the present invention can be used in a wide range of practical applications such as, for example, interior materials for an automobile, thermal insulators such as a pipe covering, cushioning materials such as a tape core and the like.

  本发明的泡沫板可生物降解、可回收、加工性好、重量轻、外观极佳、耐热性几乎令人满意，对环境更容易接受。 本发明提供了一种交联生物可降解树脂连续泡沫塑料片材，它由生物可降解树脂组成，膨胀率约为 1.5 至 50，凝胶部分约为 3% 或更多。 还提供了一种生产泡沫片材的方法，包括以下步骤(1) 用包含可生物降解树脂、可热分解发泡剂和交联促进剂的树脂组合物制备片材；(2) 用电离辐射照射所得片材，使树脂组合物交联；以及 (3) 将交联片材进行热处理，以连续制备交联泡沫片材。 因此，本发明的泡沫片材可广泛应用于各种实际领域，例如汽车内饰材料、管道覆盖层等隔热材料、胶带芯等缓冲材料等。
