Description

一种硅钙塑瓦楞复合纸板及其制备方法
技术领域
本发明属于瓦楞纸品技术领域，具体涉及一种硅钙塑瓦楞复合纸板及其制备方法。
背景技术
瓦楞纸板又被称为波纹纸板，是由多层材料粘合而成的纸板。瓦楞纸板由中间至少一层类似于瓦楞状的波纹芯纸(纸质材料或塑料材料)和至少一层纸板(牛皮纸)粘制而成。在机械性能方面，它具有非常好的延展性和弹性，和非常高的机械强度，能够承受运输过程中的摔跌和碰撞，主要用于包装中的纸箱产品。瓦楞纸箱在实际应用中的主要性能取决于以下三个因素：1、芯纸：纸质或塑料制成的瓦楞芯纸；2、面纸板的特性(两面牛皮纸)；3、纸箱本身的结构。
传统意义上的瓦楞纸板主要是由纸质材料构成，这种纸质材料虽然具有简单、方便、温度影响小的特点，而且耐光照、遮光性能也相当的出色，但是耐潮、耐湿的性能却比较差，如果将这种材料放在湿度较大的环境中使用，会严重影响其机械强度。
发明内容
本发明的目的是提供一种硅钙塑瓦楞复合纸板及其制备方法。
一种硅钙塑瓦楞复合纸板，由硅钙塑波纹芯纸和至少一层牛皮纸粘制而成；所述硅钙塑波纹芯纸以重量份计包括以下原料：聚乙烯30-45份，聚碳酸酯3-5份，碳酸钙50-65份，硅藻土2-5份，层状硅酸盐1-4份，壳聚糖1-2份，偶联剂2-4份，抗氧剂1-2份，增塑剂3-5份，硬脂酸锌2-4份。
优选地，所述聚乙烯为高密度聚乙烯，重均分子量在150000-200000。
优选地，所述碳酸钙为轻质碳酸钙。
优选地，所述层状硅酸盐选自膨润土、钠基膨润土或镁皂石。
优选地，所述偶联剂为硅烷偶联剂，选自TM-12、TM-13、TM-30、TM-42、TM-69、KH-550、KH-560或KH-570。
优选地，所述抗氧剂为受阻酚类抗氧剂，选自抗氧剂264、抗氧剂1076、抗氧剂1010或抗氧剂1098。
上述硅钙塑瓦楞复合纸板的制备方法，包括以下步骤：
步骤1，将聚乙烯、聚碳酸酯、碳酸钙、硅藻土、层状硅酸盐、壳聚糖、偶联剂、抗氧剂、增塑剂和硬脂酸锌混合，混料导入密炼机进行密炼，取出后压片，再对片材开炼、压片，冷却后，得到硅钙塑瓦楞片材；
步骤2，将硅钙塑瓦楞片材在瓦楞辊上制成硅钙塑波纹芯纸；
步骤3，在硅钙塑波纹芯纸上涂抹粘合剂，进行加热固化，形成粘结层，然后在粘结层上压合牛皮纸，制成硅钙塑瓦楞复合纸板。
本发明采用聚乙烯作为基料，添加聚碳酸酯、碳酸钙、硅藻土、层状硅酸盐后制成硅钙塑片材，再粘合牛皮纸得到瓦楞纸板。聚碳酸酯可以增强聚乙烯的强度，混入硅烷偶联剂的碳酸钙一方面可以增强片材的强度，另一方面可以促进聚碳酸酯与聚乙烯的融合；硅藻土的加入，可以防止碳酸钙的聚集，并缓解片材的冲击压力。本发明制得的瓦楞纸板具有优异的耐破强度和粘合强度，且无翘曲现象，还可以确保制得纸箱产品后具备优异的防水性能和抗冲击性能。
