一种汽车内饰用天窗遮阳板复合材料及其制造工艺
技术领域
本发明涉及一种汽车内饰用天窗遮阳板复合材料及其制造工艺。
背景技术
目前常用的汽车内饰件中的小天窗遮阳板多采用湿法、喷涂、浇注等方法生产，其中湿法PU泡绵法生产出来的产品以其优良的性能、较低的价格越来越受到天窗系统厂家的重视。但是目前湿法工艺主要三次工法和两次工法热压而成，先进行基材的压制，在压合上背层无纺布和面料，浪费工时，也不利于连续生产。而一次法生产的天窗遮阳板容易出现透胶，材料铺设时间长等缺点，遮阳板在压合成型之后还需要使用水刀进行切割，时间长，切割精度低。
发明内容
有鉴于此，本发明的目的是提供一种可有效解决透胶问题，提高良品率的汽车内饰用天窗遮阳板复合材料及其制造工艺。
本发明采用以下方案实现：一种汽车内饰用天窗遮阳板复合材料，包括自下而上依次叠放无纺布、第一隔胶膜、第一玻纤毡、PU泡绵、第二玻纤毡、第二隔胶膜和面料层。
进一步的，无纺布克重为180g/M²、第一隔胶膜克重为30g/M²、第一玻纤毡克重为200g/M²、PU泡绵克重为32KG/M³、第二玻纤毡克重为 200g/M²、第二层隔胶膜克重为36g/M²；PU泡绵通过聚氨酯胶与第一玻纤毡和第二玻纤毡粘接在一起。
一种如上所述汽车内饰用天窗遮阳板复合材料的制造工艺，包括以下步骤：（1）将无纺布和第一隔胶膜预先复合，第二隔胶膜和面料层预先复合；（2）先在PU泡绵的两面涂布一层聚氨酯胶，然后在聚氨酯胶表面喷涂一层水；（3）按自下而上依次为无纺布、第一隔胶膜、第一玻纤毡、PU泡绵、第二玻纤毡、第二隔胶膜和面料层的顺序进行叠放，然后送入油压机的模具中进行热压成型。
进一步的，步骤（2）中，聚氨酯胶的涂胶量为170~190g/M²，喷涂的水量为75~85g/M²；步骤（3）中，热压的温度为135℃，热压时间为60s。
与现有技术相比，本发明具有以下有益效果：本发明汽车内饰用天窗遮阳板复合材料通过改变遮阳板成型的材料，采用胶膜和无纺布复合材料，面料层与胶膜复合材料，有效解决透胶问题，提高良品率，节约工时，有利于连续生产。
为使本发明的目的、技术方案及优点更加清楚明白，以下将通过具体实施例和相关附图，对本发明作进一步详细说明。
附图说明
图1是本发明实施例断面图；
