技术领域
本发明涉及PP纤维织物增强材料技术领域,具体涉及一种PP纤维织物叠层复合片材的制备方法及该方法获得的片材。
背景技术
聚丙烯(Polypropylene,PP)纤维增强聚丙烯基复合材料是一种自增强热塑性复合材料,它是将PP聚合物熔融后进行高度拉伸取向,再冷却形成高度取向的PP 纱线或带,将PP纱线或带编织成织物,并与熔点较低的PP薄膜层层叠,在控制温度和压力下,使PP纱线或带保持原形,同时使熔点较低的PP树脂熔融渗透PP 织物,对PP纱线或带充分浸润并与之结合,然后冷却形成单聚合物的复合片材。该材料具有轻质、可回收的优点,且具有良好的力学性能和优异的低温抗冲击强度, 然而,该材料的刚度较低且生产工艺复杂,限制了材料的发展。
玻璃纤维增强聚丙烯复合材料是以聚丙烯为基体树脂,玻璃纤维作为增强体的复合材料。根据玻璃纤维的形态可分为连续玻璃纤维增强PP单向带、玻璃纤维织物增强PP片材、玻璃纤维毡增强的热塑性聚合物复合材料(Glass Mat Reinforced thermoplastics)等,连续玻璃纤维增强聚丙烯材料中保存了玻璃纤维宏观的完整性,因此能够完全发挥玻璃纤维所拥有的优良力学性能,使该复合材料广泛的适用于汽车工业、运输业及建筑行业。然而,玻璃纤维增强PP片层具有密度大、抗冲击性能低的缺点,使该材料的使用受限。
PP纤维自增强复合材料和玻璃纤维增强PP材料在使用过程中,由于均存在一定的缺点,导致材料的通用性受限,不利于材料更广泛的使用,因此提供一种综合性能优良的材料具有重要的意义。

(2)制备PP纤维织物:将PP纤维作为经纱平行卷绕在经轴上,然后将经轴安装在整经机上整经;将整经后的经轴安装在织机上,在织机上用梭子带动纬纱在上下开合的经纱开口中穿过,一纱一纱的构成交叉的结构,获得PP 纤维织物。
优选的,在上述PP纤维织物叠层复合片材的制备方法中,制备PP薄膜采用吹膜设备或流延膜设备。
优选的,在上述PP纤维织物叠层复合片材的制备方法中,将玻璃纤维增强PP片材、PP纤维织物和PP薄膜叠层后,采用等压式双钢带压机或平板压机进行加压和加热处理,获得PP纤维织物叠层复合片材;其中,压力在0.5-1.0MPa 之间,加热温度在100-180℃之间;
将PP纤维织物和PP薄膜以及玻璃纤维增强PP片材叠放后,使用等压式双钢带压机或平板压机加热并施加压力,使PP薄膜融化并渗透到PP纤维织物中,玻璃纤维增强PP片材通过融化的PP薄膜与PP纤维织物粘结为整体,形成PP纤维织物叠层复合片材。
一种PP纤维织物叠层复合片材,包括至少一层核心层,所述核心层包括玻璃纤维增强PP片层、两层PP薄膜层和PP纤维织物层;所述玻璃纤维增强 PP片层、一层PP薄膜层、PP纤维织物层和一层PP薄膜层依次叠放;然后使用上述方法在核心层的上面和下面同时加压、加热后获得;
在加压、加热过程中,PP薄膜层成熔融状态,渗入PP纤维织物层内部,与玻璃纤维增强PP片层贴合的PP薄膜层在渗入PP纤维织物层内部的同时,将玻璃纤维增强PP片层与PP纤维织物层粘合为核心层。
优选的,所述玻璃纤维增强PP片层的厚度为0.2-2mm,PP薄膜层的厚度为2-10μm,PP纤维织物层的厚度0.1-0.5mm。
优选的,为提高叠层复合片材的强度,核心层设有三层,三层核心层的叠放顺序为上一层核心层的玻璃纤维增强PP片层与下一层核心层的PP薄膜层贴合;该设置使叠层形成叠块后,直接在叠块的上表面和下表面同时加压、加热即可使PP薄膜层在渗入PP纤维织物层的同时实现玻璃纤维增强PP片层与PP 纤维织物层粘合,进而形成高强度的叠层复合片材。
相对于现有技术,本发明的有益效果在于:
1、在PP纤维自增强复合材料的制备过程中,将玻璃纤维增强PP片材作为特殊的铺层***其中,与PP纤维织物自增强复合材料形成整体,制备成新型PP纤维织物叠层复合片材。
2、使用本发明提供的PP纤维织物叠层复合片材,与自增强PP纤维织物复合材料相比,刚性显著提高,拉伸模量可提高2-10倍,成本显著降低,成本可降低30%-60%;与玻璃纤维增强PP复合材料相比,密度更低,冲击强度明显提高,可提高2-5倍。
3、本发明提供的PP纤维织物叠层复合片材,具有更好的可设计性,根据材料应用的实际需求,对叠层复合材料中玻璃纤维增强PP复合材料和PP纤维进行设计,具有力学性能更广的设计范围。
4、通过设置核心层,可根据对材料的性能需求进行多层核心层叠层;通过设置玻璃纤维增强PP片层、一层PP薄膜层、PP纤维织物层和一层PP薄膜层并按顺序依次叠放,使该核心层在经过加压、加热后形成整体,使该叠层复合片材在密度低的前提下具有良好的刚度和抗冲击性能,提高该叠层复合片材的实用性。

(2)制备PP纤维织物:将PP纤维作为经纱平行卷绕在经轴上,然后将经轴安装在整经机上整经;将整经后的经轴安装在织机上,在织机上用梭子带动纬纱在上下开合的经纱开口中穿过,一纱一纱的构成交叉的结构,获得PP纤维织物。
6.如权利要求1所述的PP纤维织物叠层复合片材的制备方法,其特征在于,制备PP薄膜采用吹膜设备或流延膜设备。
7.如权利要求1-6任一项所述的PP纤维织物叠层复合片材的制备方法,其特征在于,将玻璃纤维增强PP片材、PP纤维织物和PP薄膜叠层后,采用等压式双钢带压机或平板压机进行加压和加热处理,获得PP纤维织物叠层复合片材;其中,压力在0.5-1.0MPa之间,加热温度在100-180℃之间。
8.一种PP纤维织物叠层复合片材,其特征在于,该PP纤维织物叠层复合片材采用实施例1-7任一项所述的制备方法获得,该PP纤维织物叠层复合片材包括至少一层核心层,所述核心层包括玻璃纤维增强PP片层、两层PP薄膜层和PP纤维织物层;所述玻璃纤维增强PP片层、一层PP薄膜层、PP纤维织物层和一层PP薄膜层依次叠放;然后在核心层的上面和下面同时加压、加热后获得。
9.如权利要求8所述的PP纤维织物叠层复合片材,其特征在于,玻璃纤维增强PP片层的厚度为0.2-2mm,PP薄膜层的厚度为2-10μm,PP纤维织物层的厚度0.1-0.5mm。
10.如权利要求8所述的PP纤维织物叠层复合片材,其特征在于,核心层设有三层,三层核心层的叠放顺序为上一层核心层的玻璃纤维增强PP片层与下一层核心层的PP薄膜层贴合。
