为了实现上述目的,本发明采用的技术方案如下:
一种汽车车厢隔音垫的制备方法,具体包括以下步骤:
(1)各层原材料混合:所述隔音垫包括从下至上依次设置的第一饰面层、第一隔音层、混合中药层、第二隔音层及第二饰面层,将各层原材料按重量份直接混合;其中所述混合中药层主要由以下重量份原料制成:紫苏10-20份、接骨木15-25份、稠李15-20份、皂荚10-15份、桃叶10-20份、黄瓜5-10份、夹竹桃叶10-20份、毛花洋地黄10-15份、丁香10-20份、麝香10-15份、艾蒿10-30份及香蒲10-30份;
(2)注入模具:将步骤(1)中的各层混合原材料按顺序依次通过垂直落棉装置注入下模内,上模固定在成型位置处;
(3)合模成型:将步骤(2)中注入混合原料的下模移动至成型位置处,并与上模合为一体,然后加热定型,冷却后得到所述汽车车厢隔音垫。
优选地,步骤(1)中所述第一饰面层采用塑料材料制成,所述第二饰面层采用棉质材料制成。
优选地,步骤(1)中所述第一隔音层的原材料主要包括铝箔复合材料及铅的复合材料;所述第二隔音层的原材料主要包括废棉纤维、玻璃纤维、毛毡纤维棉及椰糠中的一种或多种混合而成。
优选地,步骤(1)中所述混合中药层主要由以下重量份原料制成:紫苏15份、接骨木20份、稠李17份、皂荚13份、桃叶15份、黄瓜7份、夹竹桃叶15份、毛花洋地黄13份、丁香15份、麝香13份、艾蒿20份及香蒲20份。
优选地,步骤(1)中所述混合中药层的制备方法为:按重量份准确称取紫苏、接骨木、稠李、皂荚、桃叶、黄瓜、夹竹桃叶、毛花洋地黄、丁香、麝香、艾蒿及香蒲除杂并清洗干净,置于50-70℃烘箱内烘至水分小于5%,粉碎后过筛,混合均匀后制得所述混合中药层。
优选地,步骤(3)中所述加热定型分为两个阶段进行加热:第一阶段的加热温度为180-230℃,第二阶段的加热温度为130-180℃。
