Description

一种碳纤维复合墙板及其制备工艺
技术领域
本发明涉及板材技术领域，尤其涉及一种碳纤维复合墙板及其制备工艺。
背景技术
传统复合墙板一般采用玻璃钢与硬质泡沫复合的结构，其中强度低、密度大，墙板自重较大，造成装配困难，整车重量上升。
因此需要设计一种碳纤维复合墙板及其制备工艺解决以上问题。
发明内容
本发明的目的是，提供一种碳纤维与纸蜂窝的夹层结构装饰板，以克服目前现有技术存在的上述不足。
为了实现上述目的，本发明采用了如下技术方案：
一种碳纤维复合墙板，其包括炭纤维层、气凝胶毡、硬质泡沫、饰面板，所述炭纤维层、气凝胶毡、硬质泡沫、饰面板自上而下通过粘结剂依次粘接设置，且通过袋压成型工艺压合而成。
优选的，所述硬质泡沫采用PU泡沫。
优选的，所述饰面板可根据要求选择不同材质花纹饰面板。
一种碳纤维复合墙板制备工艺，制备工艺具体为以下步骤：
S1、材料的选择、准备,碳纤维层选用0.5-2mm厚度，由4层3K预浸料进行制备；气凝胶毡选用2-4mm厚度；硬质泡沫选用密度为100Kg/m3；饰面板可根据要求选择不同材质花纹饰面板；粘接剂选用常温双组份聚氨酯胶；
S2、裁切，将S1准备好的材料按照尺寸要求配合机器进行裁切；
S3、模具摆放，将S2裁切好的材料放置到平板模具上，先将碳纤维板放置于平板模具上，且在表面涂覆一层粘接剂；
S4、滚轴预压，将S2裁切好的气凝胶毡置于S3涂好粘接剂的碳纤维板上，并用滚轴预压紧后再表面涂覆一层粘接剂，
S5、粘接，将硬质泡沫放置于S4涂好粘接剂的气凝胶毡上，然后表面涂粘接剂，再将实木饰面板放置于硬质泡沫之上，完成粘接；
S6、袋压成型工艺，将S5粘接好的材料的模具装进定制的硅胶带中，并进行封装，然后进行袋压成型工艺，先抽真空后保压，其中负压压力为-0.8～-0.9bar，保压时间120min，温度为常温；
S7、取料，将经过S6步骤的模具取出，拆封模具，取出制备完成的复合墙板，完成加工。
优选的，所述碳纤维层选用1mm厚度，气凝胶毡选用3mm厚度。
本发明的有益效果是：本发明采用真空袋压法，将产品先放置到模具中，并进行粘接，使其与模具之间形成密闭空间，将组合体放入热压罐或热箱中，在加热的同时对密闭空间抽真空形成负压，进行固化，由于粘接剂是树脂材料，大气压力的作用可以消除树脂中的空气，减少气泡，排除多余的树脂，使制品表面更加致密；本发明与现有技术相比，解决了传统墙板重量大，强度低的问题，并且在表层碳纤维板与硬质泡沫之间增加气凝胶膜，具有更好的保温、防火性能，重量相比传统复合墙板降低30％～40％；强度相比传统复合墙板提高2倍；增加了气凝胶膜，具有更好的保温及防火性能。

碳纤维层据不同要求可选用3-6层的碳纤维布进行制备。碳纤维的强度和刚度远高于玻璃钢，可以大幅提升复合墙板的强度，并减轻重量。
采用气凝胶毡，使得板具有良好的保温及防火性能。
所述硬质泡沫采用PU泡沫。采用一种高分子材料，无毒无害，具有高强度，耐溶剂等特点。
所述饰面板可根据要求选择不同材质花纹饰面板，如实木饰面板、PU饰面板等。根据需要进行选择，提高美观度，适用于不同地方，提高产品的实用性。
一种碳纤维复合墙板制备工艺，制备工艺具体为以下步骤：
S1、材料的选择、准备,碳纤维层选用0.5-2mm厚度，由4层3K预浸料进行制备；气凝胶毡选用2-4mm厚度；硬质泡沫选用密度为100Kg/m3；饰面板可根据要求选择不同材质花纹饰面板；粘接剂选用常温双组份聚氨酯胶；
S2、裁切，将S1准备好的材料按照尺寸要求配合机器进行裁切；
S3、模具摆放，将S2裁切好的材料放置到平板模具上，先将碳纤维板放置于平板模具上，且在表面涂覆一层粘接剂；
S4、滚轴预压，将S2裁切好的气凝胶毡置于S3涂好粘接剂的碳纤维板上，并用滚轴预压紧后再表面涂覆一层粘接剂，
S5、粘接，将硬质泡沫放置于S4涂好粘接剂的气凝胶毡上，然后表面涂粘接剂，再将实木饰面板放置于硬质泡沫之上，完成粘接；
S6、袋压成型工艺，将S5粘接好的材料的模具装进定制的硅胶带中，并进行封装，然后进行袋压成型工艺，先抽真空后保压，其中负压压力为-0.8～-0.9bar，保压时间120min，温度为常温；
S7、取料，将经过S6步骤的模具取出，拆封模具，取出制备完成的复合墙板，完成加工。
所述碳纤维层选用1mm厚度，气凝胶毡选用3mm厚度。
本发明的有益之处，本发明采用真空袋压法，将产品先放置到模具中，并进行粘接，使其与模具之间形成密闭空间，将组合体放入热压罐或热箱中，在加热的同时对密闭空间抽真空形成负压，进行固化，由于粘接剂是树脂材料，大气压力的作用可以消除树脂中的空气，减少气泡，排除多余的树脂，使制品表面更加致密；本发明与现有技术相比，解决了传统墙板重量大，强度低的问题，并且在表层碳纤维板与硬质泡沫之间增加气凝胶膜，具有更好的保温、防火性能，重量相比传统复合墙板降低30％～40％；强度相比传统复合墙板提高2倍；增加了气凝胶膜，具有更好的保温及防火性能。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。

S5、粘接，将硬质泡沫放置于S4涂好粘接剂的气凝胶毡上，然后表面涂粘接剂，再将实木饰面板放置于硬质泡沫之上，完成粘接；
S6、袋压成型工艺，将S5粘接好的材料的模具装进定制的硅胶带中，并进行封装，然后进行袋压成型工艺，先抽真空后保压，其中负压压力为-0.8～-0.9bar，保压时间120min，温度为常温；
S7、取料，将经过S6步骤的模具取出，拆封模具，取出制备完成的复合墙板，完成加工。
5.根据权利要求4所述的一种碳纤维复合墙板制备工艺，其特征在于：所述碳纤维层选用1mm厚度，气凝胶毡选用3mm厚度。
