Description

一种PVC板及其制造方法
技术领域
本发明属于装饰板材技术领域，主要涉及的是一种新型PVC板及其制造方法。
背景技术
PVC板具有很多优良特性，比如防潮、防霉、防水、耐磨等，在室内使用不容易老化和变形。PVC板可制成PVC地板和PVC墙板，PVC地板表面有一层透明耐磨层，其耐磨转数可达30万转远高于其它地板。同时还有较好的吸音降噪效果，吸音可达20分贝，所以在需要安静的环境如病房、图书馆、报告厅、影剧院等用PVC地板，就可以避免高跟鞋与地面敲击的声响。此外，PVC地板具备木材的各项加工性能，握钉力好，可进行钻、锯、钉、刨、粘等加工。其安装施工非常快捷，不需要做龙骨架，地面条件好的用专用环保黏结剂黏合，24小时后就可以使用。PVC地板花色品种比较丰富，但多数是走高仿真路线，包括仿地毯纹、石材纹、木地板纹等，纹路逼真美观，色彩丰富绚丽。可以任意裁剪，同时突破了普通地板的材质限制，可以用不同花色的材料组合拼接，所以可让人充分发挥创意，满足不同装饰风格的个性化需求，达到其他地板难以达到的装饰效果。脚感舒适，有弹性抗冲击，遇水发涩，不易滑倒。
但现有PVC板生产工序为混料：PVC粉、增塑剂、稳定剂、润滑剂、填充剂等原材料按一定次序投料混合；密炼：把均匀混合后的料投入密炼机进行密炼；开炼：压延制成片状半成品，即此工序生产中间层、下底层料；面料及透明料的裁切：将产品生产过程所需透明耐磨层、印刷装饰层依产品尺寸进行裁切；铺模：依产品结构配方、客户花色要求按标准作业规范进行铺设摆放并重叠整齐；热压：热压成型后，使产品层与层之间较牢固地粘接在一起；淋膜：将热压成型后的半成品经PU涂层固化处理，使产品耐磨、免上光打蜡，方便易洁之功效；回火：产品经热压成型后产品未趋于稳定，经火热处理产品物性具有较好的稳定性；养生：即静置，此工序为产品应力完全消除之关键工序，是将回火后之半成品置于恒温室冷却、静置，使每张半成品温度较为均匀后方可成型；成型：依客户要求，可成型不同规格之产品，长条方块产品等形状，均能满足客户需求。
由此可见现有PVC板的生产工艺复杂。此外现有PVC板含有增塑剂会产生迁移对人体有一定的危害。
发明内容
本发明的目的在于克服现有技术中的不足之处，提供了一种新型PVC板及其制造方法，该新型PVC板采用PVC弹性抗冲改性剂代替增塑剂解决地板弹性问题更环保性能更优。该制造方法减少了生产工序，提高了生产效率。
本发明一种新型PVC板，其特征在于该新型PVC板由上至下分别为PVC透明耐磨层、PVC仿真花纹膜层、PVC底层，其中PVC底层中含有PVC弹性抗冲改性剂。
本发明中PVC底层为PVC实心层或PVC发泡层，PVC实心层使用了聚氯乙烯(PVC)树脂、PVC弹性抗冲改性剂、碳酸钙、钙锌复合稳定剂和润滑剂，具体组分及重量份为：
PVC发泡层使用了聚氯乙烯(PVC)树脂、PVC弹性抗冲改性剂、碳酸钙、钙锌复合稳定剂、发泡剂、发泡调节剂和润滑剂，具体组分及重量份为：
本发明新型PVC板的制造方法为：将PVC底层、PVC仿真花纹膜层和PVC透明耐磨层一起至于头辊和二辊之间，通过滚压形成复合层，复合层经过进一步处理形成PVC板。
上述制造方法中的所述复合层进一步处理的方法包括：将复合层至于二辊和三辊之间，进行进一步的滚压。
上述制造方法中的所述复合层进一步处理的方法中：二辊和三辊之间采用热滚压。
上述制造方法中的头辊为复合光辊，二辊为版纹辊，通过滚压使PVC透明耐磨层表面形成仿真版纹。
上述制造方法中的二辊为版纹辊，三辊为底纹辊，复合层经热辊压后，使PVC透明耐磨层表面形成仿真版纹，PVC底层底面形成底纹。
上述制造方法中的所述PVC底层形成的方法为：按照PVC底层原料加入混合机热混搅拌到一定温度后冷却，然后加入PVC双螺杆挤出机挤出。
上述制造方法中按照PVC底层原料加入混合机热混搅拌到110-120℃放入冷混搅拌冷却到40℃，然后加入PVC双螺杆挤出机挤出。
上述制造方法中的所述PVC底层为PVC实心层或PVC发泡层，PVC实心层使用了聚氯乙烯(PVC)树脂、PVC弹性抗冲改性剂、碳酸钙、钙锌复合稳定剂和润滑剂，具体组分及重量份为：
PVC发泡层使用了聚氯乙烯(PVC)树脂、PVC弹性抗冲改性剂、碳酸钙、钙锌复合稳定剂、发泡剂、发泡调节剂和润滑剂，具体组分及重量份为：
一种PVC墙板，其特征在于：其通过将上述PVC板冷却定型牵引切割形成。
一种PVC地板，其特征在于：将上述PVC板冷却定型牵引切割，将切割后的PVC板裁切开槽形成地板。
本发明的本发明的有益效果是：通过本发明的制造方法通过滚压直接形成复合层，工艺简单。
此外，通过再次滚压使PVC透明耐磨层表面形成仿真版纹，PVC底层表面形成压花。该制造方法减少了生产工序，提高了生产效率，PVC板更加结实，纹路和压花更加清晰，漂亮。
此外，该新型PVC板采用PVC弹性抗冲改性剂代替增塑剂解决地板弹性问题更环保性能更优。
