Description

多层在线贴合式石塑板 技术领域
本发明涉及到一种多层在线贴合式石塑板。
背景技术
石塑板作为新型板材，具有以下优点：原料环保，甲醛释放量为零；材质轻薄，且具有超强的耐磨性、高弹性和超强抗冲击能力；并具有优异的防滑、阻燃、防水、防噪性能，施工安装也很方便。因此，石塑板材可作为地板、墙板、家具面板、墙线等等使用，其应用范围越来越广。而且，石塑板可回收再利用，在成本降低以及环境保护方面有很大优势。
石塑板存在一个很严重的问题，就是在经受比较大的冷热变化的时候，其放大收缩率会比较大，导致石塑板的变形或拱起。现有的石塑板如图1所示，自下而上由缓冲层100、石塑层200、装饰层300、耐磨层400和油漆层500组成。耐磨层通常是带有氧化铝的三聚氰胺甲醛树脂或聚氨酯，油漆层是在石塑板的主体形成后，在石塑板表面辊涂油漆后固化而成，在干燥的过程中，油漆材料会收缩，同时影响到下层的耐磨层同样发生收缩，导致石塑板两端上翘，如图2所示，影响板材的质量。且在板材背面贴上软木、发泡材料、木板或竹板均无法解决此问题。另外，单层的石塑板在长期使用过程中，石塑板底部和地面接触，表面和空气接触，底部和表面存在温度差，会导致石塑板受热不均，产生上翘现象。
中国专利文献CN107031136A已经公开了一种树脂复合板材及其生产方法，采用共挤方式在一台模具中挤出分层的树脂复合板材。但是共挤的方式会导致以下问题：1、挤出的树脂看似分层，但是从一台模具中挤出，一次成型，实际上还是一块树脂板材，只是树脂上中下层的材质可能会有不同，在这种情况下，树脂板材内部的应力比较大，特别是在上中下层的材质不同的情况下，更会导致树脂板材内部的应力增大，影响到树脂板材的机械性能以及平整度；2、共挤会浪费挤塑机的产能，CN107031136A的方法中如果树脂分为上下两层，需要两台挤塑机进行共挤，但是其综合产能仅有一台挤塑机的120-125％左右。
发明内容
本发明的目的是提供一种多层在线贴合式石塑板，可以克服石塑板容易上翘的缺陷。
本发明采用的技术方案为：一种多层在线贴合式石塑板，自顶层至底层依次包括上石塑层、中石塑层、下石塑层，所述上石塑层、中石塑层和下石塑层分别挤出，厚度比上石塑层：中石塑层：下石塑层＝0.5～1.5：3～4.5：0.9～1.5，上石塑层中PVC与石粉的比例为 1：2.7～1：3.5，中石塑层中PVC与石粉的比例为1：3～1：6.4，下石塑层中PVC与石粉的比例为1：2.7～1：3.8，且中石塑层中石粉的比例高于上石塑层及下石塑层中石粉比例至少0.3个点，例如上石塑层中PVC与石粉的比例为1：3.5时，则中石塑层中PVC与石粉的比例小于等于1：3.8，所述上石塑层与中石塑层之间设有玻纤布或无纺布加强层，另一玻纤布或无纺布加强层设于中石塑层与下石塑层之间，或者下石塑层下方。
优选的，所述上石塑层按重量份由以下原料组成：
Figure PCTCN2019118322-appb-000001
优选的，所述上石塑层中还添加有DOTP，DOTP的添加量为4～10份，添加DOTP时，增韧剂的重量份改为0～10份。
优选的，所述上石塑层中还包括100～150份的生产回料，添加生产回料时，调整各原料的加入量，使得计入生产回料中各原料的量后，原料的配比仍在上述的配比范围内。
优选的，所述中石塑层按重量份由以下原料组成：
Figure PCTCN2019118322-appb-000002
优选的，所述中石塑层中还添加有DOTP，DOTP的添加量为4～10份，添加DOTP时，增韧剂的重量份改为0～10份。
优选的，所述中石塑层中还包括100～150份的生产回料，添加生产回料时，调整各原料的加入量，使得计入生产回料中各原料的量后，原料的配比仍在上述的配比范围内。生产回料通常是指在生产过程中产生的废料或未达标的产品，生产回料中同时包括上中下石 塑层，生产回料中各组分的配比在上下石塑层与中石塑层之间，因此加入生产回料时需要预先计算生产回料中各组分的配比，并调整加入的其他组分的重量，以使各层的配比落入预设的配比范围内。
含有玻纤网的生产回料可能会对产品造成不利的影响，比如较长的玻璃纤维突出在上石塑层表面，可能会产生将脚刺伤的风险。为此，对生产回料进行粉碎加工，使其粒径小于10目，在粉碎加工的过程中，同时采用风选的方式，将大部分玻璃纤维吹离生产回料，小部分已粉碎至尺寸在10目以下的玻璃纤维加入配方中，可以起到增强石塑板的冲击强度、挠曲强度、拉伸强度、断裂伸长率等性能的作用。
优选的，所述下石塑层按重量份由以下原料组成：

所述挤出装置通常包括高速混料机、低速混料机、料仓和挤出机，挤出机为平行双螺杆挤出机、锥形双螺杆挤出机或单螺杆挤出机。物料在高速混料机中进行高速搅拌混合，混料温度在130-160℃，使得PVC包裹石粉颗粒，然后送入低速混料机中进行冷却，冷却到30℃以下或者冷却到室温，再送入料仓储存，料仓中的物料送入挤出机中挤出成层状结构。
本发明的有益效果如下：
1、本发明是在专利文献CN107031136A的基础上发展起来的。本发明将石塑层分成石粉含量不同的三层，之间可用玻纤布或无纺布分隔并起到加强作用。中石塑层厚度大，石粉含量高，不但可以降低板材的成本，而且中石塑层PVC含量低，不容易受到热胀冷缩的影响，收缩率较低；上石塑层和下石塑层PVC含量高，弹性强，加强层会嵌合到石塑层内，使得石塑层结合成一个整体，可以对抗耐磨层和油漆层的收缩力以及冷热不均导致的内应力，增强板材的稳定性，减少收缩率，使板材保持平衡，防止板材翘曲。本发明采用分别挤出各层，再热压贴合的方式，分别挤出的两层或三层结构的石塑板的应力明显降低，且将玻纤布或无纺布热压到各层之间，可以明显使各层平衡和对称，制得的石塑板平整、稳定，不易产生翘曲。而且分别挤出的时候，使用三台挤塑机，产能即为一台挤塑机的300％，没有产能上的损失，节约成本。另外，采用分别挤出的方式，可以严格控制各层的配比和厚度，确保在使用不同厚度的耐磨层时，保证整体板材的稳定和平整。
2、挤出的石塑材料温度较高，使得石塑层之间以及加强层与石塑层之间可以很好的结合在一起，各层之间的结合力强。将装饰层、耐磨层、缓冲层覆在石塑材料上，石塑材料的余温可以使覆材很好的贴合在石塑材料上，加强层可以使各层之间更好的结合到一起。缓冲层可以起到缓冲静音的作用。
3、在上石塑层中添加DOTP，可以使上石塑层柔软度和弹性更好，作为地板时具有良好的脚感。
4、通常而言，石塑层中的PVC包裹在石粉即碳酸钙颗粒外，包裹成圆形或椭圆形，临近的PVC颗粒表面结合在一起，提供石塑板成型的附着力。由于中石塑层中PVC含量 低，无法完好的包裹碳酸钙颗粒，可能会将碳酸钙颗粒包裹成纺锤型或不规则形状，导致中石塑层临近的PVC颗粒之间接触的面积小，附着力也小，使得中石塑层比较脆，容易断裂破损。在中石塑层中加入DOTP增塑剂，可以使PVC更好的包裹住石粉，PVC颗粒之间接触的面积变大，石塑板内部附着力更强，中石塑层韧性更高，不容易断裂破损。
5、本发明采用石塑材料挤出和各层的辅材铺设一体成型的方法和生产系统，可简化生产流程，进一步降低成本。每铺设一层玻纤布或石塑层后均及时用加热辊压的方式使各层之间在石塑材料尚未硬化的时候就结合在一起，使得各层材料之间的结合更紧密。小辊和第五对辊为冷辊，因为石塑板为热板，冷辊印在其上，可以使面纹和背纹的纹路更清晰，也可以起到使石塑层逐步降温硬化的作用，石塑板的韧性更强。
6、通常的操作先挤出下石塑层、再挤出中石塑层，最后挤出上石塑层，但这不是唯一的顺序，也可以先挤出中石塑层并贴上上下层的玻纤布或无纺布，然后在中石塑层的上方挤出上石塑层，下方挤出下石塑层再辊压贴合也是可行的。
7、上石塑层和下石塑层中PVC含量较高，材质柔软。对于该生产系统而言，同时配置三台挤出机需要的厂房空间相当之大，为节约空间，也可以将上石塑层和下石塑层预制好，做成所需厚度的卷材，采用挤出机挤出中石塑层后再将上石塑层和下石塑层铺上后加热辊压，刚挤出的中石塑层具有较高的温度，通过加热辊压的方式，使上石塑层和下石塑层处于软化的状态，各层之间可以很好的粘合到一起。
8、上中下三层石塑层的板可用于开槽制作锁扣型板，但毕竟成本比较高，也可以只用上下两层石塑板，制成厚度虽薄，但富有弹性且不易产生形变的板材。
9、在下石塑层表面压出背纹后再粘合缓冲层，一是背纹可以在石塑板上起到加强筋的作用，对石塑板各部位起到拉结的作用，使石塑板成为一个整体，更不易变形；二是粘合缓冲层时，胶水或涂布的发泡PVC糊状材料会填充入背纹之间的缝隙中，提高胶水或发泡PVC与缓冲层之间的接触面积，使缓冲层粘合更牢固，静音效果更佳。
