Description
技术领域
本发明属于建材技术领域,涉及一种具有缓冲功能的抗压PVC装饰板。
背景技术
现代家私中,柜、橱、桌、床多采用装饰板进行加工。此装饰板为一种人造板材,用高温高压胶合剂制成的复合材料,板面具有各种木纹或图案,光亮平整,色泽鲜艳美观。
PVC装饰板是装饰板领域中最常见的一种,具有轻质、隔热、保温、防潮、阻燃、施工简便等特点。但是目前也存在一些缺点,一是自身强度一般,在堆积或碰撞中容易出现变形或损坏等问题,二是安装过程中,主要以底部胶粘为主,相邻的PVC装饰板的接触面是平面,只能靠工人对缝找齐,精度较差。
发明内容
根据以上现有技术的不足,本发明提供了一种具有缓冲功能的抗压PVC装饰板,具有一波浪形加强缓冲层,在挤压或者碰撞的时候可以起到空间的缓冲,避免造成PVC装饰板整体的损坏或者变形,同时,该PVC装饰板还具有抗老化、耐腐蚀、耐磨、防火等特性,并且采用插接结构,易于安装。
本发明所述的一种具有缓冲功能的抗压PVC装饰板,其特征在于,由下至上依次包括基材层、波浪形加强缓冲层、装饰层和耐磨层,所述基材层与波浪形加强缓冲层之间通过PU胶水粘接连接,所述波浪形加强缓冲层与装饰层之间通过热压成型工艺复合,所述装饰层与耐磨层之间通过淋膜工艺复合;其中,所述波浪形加强缓冲层一体成型且为沿水平方向包括两端的水平段和中间的波浪段,所述波浪段有若干个均匀分布的单波组成,每个所述单波的波高和波宽的比例为1:3~4。
其中,优选方案如下:
所述基材层的两侧分别设置有插接槽和插接件,所述插接槽与相邻PVC装饰板的插接件相配合。
所述插接槽为向侧面开设的T型缺口,所述插接件是与T型缺口相配合的T型件。
所述插接槽为向侧面开设的圆弧缺口,所述圆弧缺口的圆心角大于180度,所述插接件是与圆弧缺口相配合的半球形件。
所述基材层为PVC发泡板。
所述波浪形加强缓冲层按照重量份数计,由以下原料制备而成:尼龙-690~120份、导热填料20~40份、玻璃纤维10~15份、阻燃剂20~50份、偶联剂0.2~0.5份、抗氧剂0.1~0.2份;其中,所述导热填料为氢氧化镁、氧化镁、氧化锌、氮化硼、钛白粉中的一种或任意几种的组合,所述的玻璃纤维为无碱玻璃纤维,直径12μm~23μm,所述阻燃剂为聚磷酸铵、磷酸三苯酯或磷酸三异丙苯酯中的一种或任意几种的组合,所述偶联剂为硅烷偶联剂,选自KH-550、KH-560或KH-570中的一种,所述抗氧剂为抗氧剂1010、抗氧剂1790、抗氧剂1098、抗氧剂168、抗氧剂DLTDP中的一种或几种的混合物。制备时,将除玻璃纤维以外的其它原料放入混料机中混合10~20min,使其充分混合,然后将混合物加入到双螺杆挤出机进行熔融,加工温度为200~280℃,螺杆转速350~380r/min,在侧入口喂入玻璃纤维,经双螺杆挤出机塑炼、压延机压延、牵引经真空定型模真空水冷却定型后即得波浪形加强缓冲层。
所述装饰层为压花膜。
所述耐磨层为经紫外线固化的UV涂层。
本发明所述的PVC装饰板的制备工艺按照目前常规工艺生产即可,并无特殊要求。具体是在波浪形加强缓冲层的底部与基材层的接触面上涂覆PU胶水,然后静压成型使波浪形加强缓冲层与基材层复合在一起,在波浪形加强缓冲层先热滚压装饰层,再在装饰层上淋膜UV油、经紫外线固化形成耐磨层。
本发明的优点在于:
(1)具有波浪形加强缓冲层,以尼龙-6为主体制作而成,并且针对PVC装饰板在配方上做了调整,并且添加了玻璃纤维,使其强度和韧性明显高于基材层,经测试,波浪形加强缓冲层的拉伸强度达到130MPa,弯曲强度达到200MPa,缺口冲击强度达到15kJ/m2,起到一定的缓冲作用,在挤压或者碰撞的时候可以起到空间的缓冲,避免造成PVC装饰板整体的损坏或者变形,波浪形加强缓冲层自身的强度又可以保证PVC装饰板本身的形状。配方中添加了阻燃剂,根据DIN5510-2标准,结果如下,燃烧等级达到S5级要求(无产品燃烧破坏长度,无后燃烧时间),冒烟等级达到SR2≤50(%*min),液态等级达到ST2(没有滴落现象)。
(2)耐磨层为经紫外线固化的UV涂层,具有耐化学腐蚀、附着力强、硬度高、耐磨、价格便宜等优点,显著提高了PVC装饰板外表面耐磨性,不易划伤,显著延长了使用寿命。
(3)基材层采用PVC发泡板,价格低廉,具有成本优势。
(4)装饰层为压花膜,可以自由设计图案,如木质图纹、几何图形、仿石图纹等等,装饰效果好。
(5)PVC装饰板采用插接结构,相邻的PVC装饰板依次插接,施工过程中更加简单,并且能够减少胶水能原料的使用。
