The invention provides a heat insulation pad for an automobile engine. The heat insulation pad comprises a regenerated cellulose fiber layer, a sponge rubber layer, a melamine resin layer, a polyethylene foaming material layer, a flame-retardant glass wool layer and a PVC material layer; the sponge rubber layer is arranged at the upper end of the melamine resin, and the regenerated cellulose fiber layer is arranged at the upper end of the sponge rubber layer; the polyethylene foaming material layer is arranged at the lower end of the melamine resin, the flame-retardant glass wool layer is arranged at the lower end of the polyethylene foaming material layer, and the PVC material layer is arranged at the lower end of the flame-retardant glass wool layer. The selected material layers have high heat resistance, all the layers are bonded together through silica sol, and then the whole is subjected to hot pressing in a hot pressing mode, so that the strength of the melamine resin layer is improved, occupied space is reduced, the whole thickness is reduced, meanwhile, the hardness is higher, higher high temperature resistance is achieved, and the shockproof, sound insulation and heat insulation effects are further enhanced.

    本发明提供一种汽车发动机隔热垫,所述隔热垫包括再生纤维素纤维层、海绵橡胶层、三聚氰胺树脂层、聚乙烯发泡材料层、阻燃玻璃棉层、PVC材料层;所述三聚氰胺树脂上端为海绵橡胶层,所述海绵橡胶层上端为再生纤维素纤维层;所述三聚氰胺树脂下端为聚乙烯发泡材料层,所述聚乙烯发泡材料层下端为阻燃玻璃棉层,所述阻燃玻璃面层下端为PVC材料层。本发明选取的材质层均具有较高的耐热性,先用硅溶胶将各层粘接起来,再通过热压的方式将整体进行热压,增加了三聚氰胺树脂层的强度,减少了空间的占用,整体的厚度变更薄,同时硬度更强,更加耐高温,防震、隔音和隔热效果也更进一步增强。
