Description

改性环保PVC复合木塑颗粒
技术领域
本发明涉及高分子材料领域，特别是改性环保PVC复合木塑颗粒。
背景技术
PVC木塑复合材料(Wood-Plastic Composites,WPC)是国内外近年蓬勃兴起的一类新型复合材料，指利用聚氯乙烯，与木粉、稻壳、竹粉等植物纤维混合成新的木质材料，混配和造粒而制备的复合材料颗粒。再经挤压、模压、注射成型等塑料加工工艺，生产出的板材或型材。在环保方面PVC木塑制品满足一些特定性能和工艺成型范围要求方面越来越高，PVC制品最早是直接用聚氯乙烯和木粉及助剂混合后，直接用混合后的粉体经热挤压而成型的工艺基本被淘汰。取而代之的是，先将混合物充分混配，然后经双螺杆造粒机造粒，也就是生产成PVC木塑颗粒，然后再经挤压、模压、注射成型等塑料加工工艺，生产出的板材或型材。这种用颗粒制备成的型材，工艺稳定，性能大幅提高。尤其是环保PVC木塑制品，基本上都是用PVC颗粒来生产的。
发明内容
为解决上述问题，本发明的目的是提供一种尺寸稳定性好，重量轻，不会产生变形、龟裂、曲翘、不会虫蛀、发霉、防腐蚀、耐老化、易清洁、阻燃；可锯、可刨、可钉二次加工性能好的改性环保PVC复合木塑颗粒。
为实现上述目的，本发明的技术方案：
改性环保PVC复合木塑颗粒，包括树脂、木粉、稳定剂、白炭黑、碳酸钙、增强剂、增韧剂、丙烯酸、硬脂酸、钛白粉、碳酸氢钠，其特征在于，所述的树脂54-58重量份，木粉18-22重量份、稳定剂3-5重量份、白炭黑1-4重量份、碳酸钙4-6重量份、增强剂3-5重量份、增韧剂2-5重量份、丙烯酸1-3重量份、硬脂酸1-3重量份、钛白粉1-4重量份、碳酸氢钠1-2重量份。
作为优选，所述的树脂为PVC树脂。
作为优选，所述的稳定剂为环保稳定剂型号为K132B。
作为优选，所述的增强剂为MBS。
作为优选，所述的增韧剂为CPE。
本发明的有益条件在于：与木材比，尺寸稳定性好，不会产生变形、龟裂、曲翘、不会虫蛀、发霉、防腐蚀、耐老化、易清洁、阻燃；可锯、可刨、可钉、可上漆二次加工性能好；与塑料比，具有天然的芳香，木质感和木纹。
具体实施方式
下面结合实施例对本发明作进一步的描述。
