木塑复合材料具有植物纤维和塑料的双重优点,具有绿色环保、可循环利用的特点,目前被广泛应用于建筑、装饰及户外景观等领域。但木塑复合材料存在颜色单一、附加值低等问题。对木塑复合材料的原料来源、工艺参数和使用场所的环境条件等影响材料外观颜色的主要因素进行了综述,同时对制备彩色木塑复合材料的研究方法进行了系统的介绍,提出了未来木塑行业将向功能化和智能化的方向发展。 WPC has the dual advantages of plant fiber and plastic, has the characteristics of green and recyclable, and is widely used in the fields of construction, decoration and outdoor landscape. However, the existence of single-color WPC composite materials, low value-added and other issues. The main factors that affect the appearance color of materials, such as the origin of raw materials, the process parameters and the environmental conditions of the wood-plastic composites, are summarized. Meanwhile, the research methods of preparing color wood-plastic composites are systematically introduced, Plastic industry will be functional and intelligent direction.
