Description
技术领域
本发明涉及汽车内饰材料技术领域，尤其涉及一种汽车内饰用防水环保型纸蜂窝复合板及其制备方法。
背景技术
随着世界经济的高速发展和人民生活水平的稳步提高，汽车作为人类社会的一种代步工具，把人们带入现代化的文明社会。汽车工业的迅速发展也带动了相关行业的发展，其中汽车内饰材料就呈蓬勃发展之势。汽车内饰是汽车的一个重要组成部分，通常要求具有美观、柔软、舒适、保暖、弹性好、无异味等特点。
目前，国内汽车内饰材料多为硬质聚氨酯板、麻纤板或ABS板，在梅雨季节时易生菌霉变，低温发脆比较严重，耐潮性差，遇水易变形；而且近年来，车室内VOC的排放问题引起了人们的高度关注，VOC是常温下易于挥发的有机物，包括甲醛、甲苯、苯乙烯等。车内VOC主要来源是各个零部件共同挥发而产生，主要挥发的内饰材料有塑料件、泡沫、皮革制品和涂料等。当气温达到一定高度时，汽车内饰材料会释放出这些挥发物质，产生令人不舒服的气味，甚至引起头疼、干咳和过敏等不适反应，对乘员的身体造成伤害。
发明内容
本发明的目的是克服现有技术的不足，提供一种汽车内饰用防水环保型纸蜂窝复合板及其制备方法，具有低气味低VOC、耐低温、耐热老化、永久耐湿防潮、防霉无异味等特点，长期使用不变形、无异味、无霉变，符合环保要求，无气味和散发性良好，界面结合牢固，易于成形。
为了实现上述目的，本发明采用如下技术方案：
一种汽车内饰用防水阻燃环保型纸蜂窝复合板，所述复合板自下而上由无纺布、热熔胶膜、竹纤维毡、热熔胶膜、纸蜂窝芯、热熔胶膜、GMT毡、热熔胶膜复合而成；
所述热熔胶膜原料按重量份计，包括三元共聚聚丙烯20-30份、乙烯-丙烯共聚物10-20份、C5/C9共聚树脂5-10份、高分子量PP蜡2-4份、抗氧剂1-2份；
所述竹纤维毡按重量份计，包括竹纤维40-50份、水镁石粉5-10份、海泡石粉5-8份、脲醛树脂胶黏剂10-15份、硅丙乳液7-12份、纳米二氧化钛1-2份、蓖麻油4-6份；制备方法：将水镁石粉、海泡石粉、纳米二氧化钛混合后加入蓖麻油于120-150℃条件下搅拌处理1-2小时，再与脲醛树脂胶黏剂、硅丙乳液混合搅拌均匀，加入竹纤维中，再干燥处理，经过机械铺装成型，热压、冷却、裁切处理后得竹纤维毡。
所述纸蜂窝芯是由六边形孔格和三角形孔格组成的蜂窝状结构。
所述GMT毡由重量比为6:4的无碱玻璃纤维和改性聚丙烯纤维采用真空浸润技术制得。
所述热熔胶膜克重为80-100g/m2。
所述的汽车内饰用防水阻燃环保型纸蜂窝复合板的制造方法，包括以下步骤：在复合机的传送带上自下而上依次放卷、平铺、叠放无纺布与热熔胶膜、竹纤维毡，再放置热熔胶膜和纸蜂窝芯，在纸蜂窝芯上方放卷热熔胶膜，铺放GMT毡，再平铺叠放热熔胶膜，并在180-200℃、0.5-1MPa下进行热压复合，冷却、切割，得到纸蜂窝复合板。
所述热熔胶膜采用现有技术的制备方法制备。
与已有技术相比，本发明的有益效果如下：
(1)本发明的汽车内饰用防水环保型纸蜂窝复合板，具有低气味低VOC、耐低温、耐热老化、永久耐湿防潮、防霉无异味等特点，长期使用不变形、无异味、无霉变，符合环保要求，无气味和散发性良好，界面结合牢固，易于成形。
(2)本发明的热熔胶膜采用三元共聚聚丙烯改性的热熔胶能满足低温不开胶的环境要求，而且在高温下可以牢固复合，粘接强度高，满足纸蜂窝复合板不软化变形、低温不开裂的情况，使纸蜂窝复合板结构层之间的粘接强度高，避免在压力下蜂窝夹层结构的塌陷，增强了复合板的屈服强度、剪切强度，提高复合板承载能力。
(3)本发明增加了竹纤维毡，竹纤维毡通过纳米二氧化钛对纤维材料复合改性使材料具有天然的抗菌防菌、发生负离子、净化空气、去除异味功能，再结合水镁石粉、海泡石粉的添加，提高耐候性、防火阻燃性，提高安全性，同时具有减轻疲劳、去除异味、净化空气的作用，实用性强。
