The invention relates to a preparation method of flame-retardant high-performance polypropylene and an automobile foot mat prepared from the same. The material comprises the following components in parts by weight: 100-120 parts of a polypropylene matrix; 9-12 parts of a flame retardant; 0.1 to 2.5 parts of an antioxidant; wherein the polypropylene matrix is a high-molecular polymer matrix with a net structure, which is obtained by cross-linking polypropylene with a first copolymer of polyacrylate and then cross-linking polypropylene with a segmented copolymer; the flame retardant is a hydrotalcite flame retardant with a self-crosslinking group, the flame retardant is controlled in a matrix under the action of positive and negative charges and crosslinking, the dispersing performance and compatibility of the flame retardant are remarkably improved, polypropylene is endowed with excellent flame retardant property, and the mechanical property of the material is greatly improved. According to the polypropylene composite material prepared by the technical scheme, the foot mat hardened at a low temperature still has good rigidity and toughness, is not easy to deform in a treading stress process, and can be used for manufacturing an automobile foot mat.
一种阻燃高性能聚丙烯制备方法及其制备的汽车脚垫。该材料包含以下组分及重量份数:聚丙烯基体100~120份;阻燃剂9~12份;抗氧剂0.1~2.5份;其中,聚丙烯基体,是由聚丙烯交联聚丙烯酸酯的第一共聚物,再交联嵌段共聚物得到的高分子的网状结构聚合物基体;阻燃剂为带自交联基团的水滑石阻燃剂,通过正负电荷和交联的作用,使得阻燃剂被控制在基体中,其分散性能和相容性能都显著提高,赋予聚丙烯优异的阻燃性能,并大幅提高材料的力学性能。通过本技术方案制备的聚丙烯复合材料,低温下变硬的脚垫仍然具体良好的刚性和韧性,在踩踏受力过程中不容易变形,可用于制作汽车脚垫。
