Description
技术领域
本发明涉及塑木地板技术领域,尤其涉及一种可适应超高重压的户外用塑木地板。
背景技术
木塑复合材料(Wood~polymer Composites,缩写WPC),是以木纤维或植物纤维为主要组分,经过预处理使之与热塑性塑料树脂或其他材料结合而成的一种新型材料。这种材料能够充分发挥材料中各组份的优势,克服单一材料的缺点,不仅能够改进材料的物理力学性能和加工性能,降低成本并扩大应用范围,还提高了材料的附加值。由于产品呈结晶态(木纤维或植物纤维)和无序态(树脂)的多相状态,使其既具有木纤维或植物纤维的高强度、高弹性,又具有聚合物基体的高韧性,并且抗冲击强度高、热伸缩性和吸水性均比木材小、尺寸稳定性好、耐磨、耐化学腐蚀、不怕虫蛀、非易燃、兼具木材和塑料的双重加工性能。其可以通过如热压成型、注塑成型、挤出成型等成型工艺,而制得木塑复合材料的制品,即木塑复合型材。
传统的户外用木塑复合材料比较关注防晒、高强度、耐磨等技术参数,但是部分户外用塑木地板需要承受重型开车或者重型机械等重物的高压,故有必要研究一种可适应超高重压的户外用塑木地板。
发明内容
基于背景技术存在的技术问题,本发明提出了一种可适应超高重压的户外用塑木地板。
本发明的技术方案如下:
一种可适应超高重压的户外用塑木地板,按重量份计由以下成分组成:聚乙烯 100份、木粉30-45份、马来酸酐接枝聚乙烯 12-15份、滑石粉 12-15份、无机增强剂 8-15份、水泥熟料5-15份、色粉5-15份、硅烷偶联剂1-2份、煅烧高岭土2-8份、硅酸乙酯1-3份、脱模剂0.1-0.8份、抗氧化剂 3-8份、抗紫外光吸收剂2-3份、抗冻剂1-2份、防霉剂3-5份和玻璃纤维 25-35份。
优选地,所述的无机增强剂为博耐特和棕刚玉的混合物。
进一步优选的,所述的博耐特和棕刚玉的质量比为1:(6-10)。
优选的,所述的硅烷偶联剂为硅烷偶联剂kh550或硅烷偶联剂kh570。
优选的,所述的抗氧化剂为受阻酚类抗氧剂。
优选的,所述的博耐特和棕刚玉的粒径为800目。
马来酸酐接枝聚乙烯通过化学反应的手段在聚乙烯分子链上接技数个马来酸酐分子,使产品既具有聚乙烯的良好加工性和其它优异性能,又具有马来酸酐极性分子的可再反应性和强极性,利于作为偶联剂和再反应改性剂使用,在塑料领域具有广泛的用途。一般可以用于聚丙烯、高密度聚乙烯的填充、玻纤增强的偶联剂,色母粒的载体树脂,工程塑料的增韧改性剂、塑料共混物的增容剂、防雾地膜的延长防雾期改性剂等。
博耐特基于六铝酸钙(CA6)矿物相的一种新型合成致密耐火骨料。六铝酸钙是CaO-Al2O3二元系统相图中Al2O3含量最高且熔点最高的化合物,属于六方晶系,在垂直于C轴方向优先形成片状和板状结构。理论密度是3.79g/cm3,熔点为1875℃,热膨胀系数为8.0×10-6℃-1。六铝酸钙作为一种拥有优良性能的新型耐火材料,使其已经成功应用在炼钢和炼铝工业当中。
本发明的有益之处在于:本发明的可适应超高重压的户外用塑木地板,按重量份计由以下成分组成:聚乙烯 100份、木粉30-45份、马来酸酐接枝聚乙烯 12-15份、滑石粉12-15份、无机增强剂 8-15份、水泥熟料5-15份、色粉5-15份、硅烷偶联剂1-2份、煅烧高岭土2-8份、硅酸乙酯1-3份、脱模剂0.1-0.8份、抗氧化剂 3-8份、抗紫外光吸收剂2-3份、抗冻剂1-2份、防霉剂3-5份和玻璃纤维 25-35份。本发明的户外用塑木地板,为了达到更好耐水浸泡效果,加入了水泥熟料、硅烷偶联剂和玻璃纤维,可以有效提升塑木地板的强度;本发明中还加入了博耐特和棕刚玉组成的无机增强剂,可以有效提升塑木地板的致密性,从而进一步提升塑木地板的抗压强度。
