Description

新型抗菌木塑橱柜板及其制备方法
技术领域
本发明涉及一种木塑板，更确切地说，是一种新型抗菌木塑橱柜板及其制备方法。
背景技术
木塑复合材料是一种用木粉、木纤维或植物纤维填充热塑性聚合物经高温高压处理制成的材料，兼有木材和塑料的优点，它的主要原料是农林废弃物(如废弃木材、农作物稻秸秆等)和热塑性塑料。由于木塑材料中的木质纤维并不能被塑料完全包覆，且材料中还有一定的孔隙率，潮湿环境中，水分很容易沿着空隙进入到木质纤维中，导致木质纤维膨胀和发霉，引起木塑材料发霉和腐败、褪色和变色，研究发现，引起发霉的霉菌主要有黑曲霉、绳状青霉、球毛壳霉、绿粘帚霉、出芽短梗霉等，引起腐败的木腐真菌主要包括白腐菌和褐腐菌两大类。这将大大影响木塑材料的美观，降低其实用性和寿命。
发明内容
本发明主要是解决现有技术所存在的技术问题，从而提供一种新型抗菌木塑橱柜板及其制备方法。
本发明的上述技术问题主要是通过下述技术方案得以解决的：

环保稳定剂 3-6份；
润滑剂 0.5-2份；
ACR加工助剂 5-7份；
发泡剂 1-2份；
碳化钨粉末 0.1-0.5份。
作为本发明优选的实施例，所述的复合抗菌剂为纳米TiO2/聚丙烯(PP)复合抗菌剂；
所述的钙质填充剂为1000-1500目的轻质碳酸钙；
所述的增塑调节剂为苯乙烯和己二酸中的至少一种；

所述的润滑剂为硬脂酸；
所述的ACR加工助剂为二辛脂和双甲酯中的至少一种；
所述的发泡剂为小苏打和偶氮酰胺中的至少一种；
所述的碳化钨粉末为200-300目。
本发明还公开了一种制备如前述的新型抗菌木塑橱柜板的制备方法，包含步骤：
1)、将塑料基体与复合抗菌剂送入混料机，在70℃温度下搅拌1.5个小时，得到处理后的塑料基体，冷却备用；
2)、将处理后的塑料基台和其余原料按送入混料机；
3)、将混好的原料加入双层挤出机的进料口，加热至120～200℃挤出，挤出机机筒温度130～200℃，模具温度130～220℃，主机转速8～30转/min,喂料转速8～30转/min，共挤机温度100-230℃，转速5～15转/min；
4)、挤出后经压延成型、牵引和切割。
本发明的新型抗菌木塑橱柜板具有以下优点：具有抗菌性，能够很好的抗菌，防霉，其内里层的抗菌层的孔隙率较低，具有较好的防水性，且原料来源广泛，成本低，节能环保，是取代普通密度板和多层板材的理想浴室装饰板。
具体实施方式
按照下表进行备料：
三个实施例中份分别采用:
将上述备好料的三个实施例分别进行以下加工：
1)、将塑料基体与复合抗菌剂送入混料机，在70℃温度下搅拌1.5个小时，得到处理后的塑料基体，冷却备用；
2)、将处理后的塑料基台和其余原料按送入混料机；
3)、将混好的原料加入双层挤出机的进料口，加热至120～200℃挤出，挤出机机筒温度130～200℃，模具温度130～220℃，主机转速8～30转/min,喂料转速8～30转/min，共挤机温度100-230℃，转速5～15转/min；
4)、挤出后经压延成型、牵引和切割。
分别取实施例1、实施例2和实施例3的产品进行抗菌实验，抗菌实验标准为ASTME2180，选用菌种为黑曲霉菌和白腐菌，实验结果如下表所示：
抑制率 实施例1 实施例2 实施例3
黑曲霉菌 94％ 97％ 99％
白腐菌 93％ 96％ 97％
本发明的新型抗菌木塑橱柜板具有以下优点：具有抗菌性，能够很好的抗菌，防霉，其内里层的抗菌层的孔隙率较低，具有较好的防水性，且原料来源广泛，成本低，节能环保，是取代普通密度板和多层板材的理想浴室装饰板。
由于增加了碳化钨粉末，有效提高了木塑材料的耐磨性。
为了提高本发明的木塑复合材料的强度，在配料时可以加入石墨烯，加入量是PVC树脂粉重量的0.1％-0.5％，制得的板材硬度至少能提高10％，而弯曲弹性模量至少能提高5％。
此外，为了能够进一步提高材料的强度及耐腐蚀能力，可以添加将金属泡沫打成粉体的材料，金属泡沫可以是泡沫镍、泡沫铜、泡沫钛、泡沫铁镍等，优选泡沫钛。
将泡沫钛粉碎为30到50目的粉体，按照实施例1～实施例3，分别添加0.3、0.6和0.9的重量份进行添加，其余制备工艺同上。
由于泡沫钛粉碎后，粉体具有不规则的形状，能够很好地与基底与因此能够更好地固化到基体内。强度与不添加的相比，能够提高10～15％。而钛本身具有很好的耐腐蚀能力，从而能够进一步提高木塑复合材料的耐腐蚀性能。
为了提高本发明的木塑复合材的抗菌性能，在配料时可以加入纳米银，纳米银的粒径在25-50纳米之间，加入量为PVC树脂粉重量的1％-5％，加入纳米银后，制得的板材的抗菌性得到有效提高，经过ASTME2180标准的大肠杆菌抗菌测试，杀菌率达到90％以上。
不局限于此，任何不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。
