所述XPE层与车体表面相配合，所述阻尼隔音毡位于所述XPE层的上表面，所述防静电发泡EVA层位于所述阻尼隔音毡的上表面，所述硅橡胶层位于所述防静电发泡EVA层的上表面，所述硅橡胶层上均匀设置有通气孔7，所述通气孔7内塞有化纤品碎纤维6；所述抗静电无纺布层5位于本发明的外表面；
本发明的制备方法为：
a.通过硅溶胶粘接抗静电无纺布层和硅橡胶层；向硅橡胶层上的通气孔内塞入化纤品碎纤维，通过硅溶胶将防静电发泡EVA层粘接于硅橡胶的另一外表面，形成本发明的半成品一；
b.通过硅溶胶粘接XPE层与阻尼隔音毡，形成本发明的半成品二；
c.将阻尼隔音毡与防静电发泡EVA层的接触面涂上粘结剂，通过模压机将半成品一与半成品二模压复合，将六个结构层复合为一体；
d.水切割:将模压复合为一体的六个结构层经切割成型，形成本发明产品件。
进一步的，所述XPE层的厚度为3～5mm，所述阻尼隔音毡2的厚度为0.8～1.2mm，所述防静电发泡EVA层3的厚度为3～5mm，所述硅橡胶层4的厚度为5～7mm，所述抗静电无纺布层的厚度为2～3mm。
进一步的，所述通气孔7的孔径为8～12mm。
本发明的有益效果为：本发明设XPE层为底层，该底层泡孔细、抗拉强度高、弹性好，可与发动机很好的贴合，提高了的产品的安装质量，避免出现产品与发动机之间的缝隙，使隔热垫具有优良的吸音、隔音、隔热效果；采用阻尼隔音毡，使本发明隔音效果有非常好地保证；采用的防静电发泡EVA层、硅橡胶层、抗静电无纺布层使本发明有非常好的防静电功能，回收利用化纤品碎纤维，透气隔音，节约生产成本；在制备方法上，本发明采用热压一次成型，保证了各层间的连接质量。本发明质量轻，吸音、隔热、减震效果好，所采用的材料在封闭的空间使用无刺鼻异味，环保无污染。
