为提高竹粉/高密度聚乙烯（HDPE）复合材料的耐水性，研究了塑料含量、偶联剂和微纤化纤维素（MFC）添加量对配方的影响，并对其流变性能和力学性能进行了评价。以等量竹粉和HDPE为基本组分，采用注射成型法制备了竹粉/HDPE复合材料，测定了复合材料的熔融流动性、拉伸强度和拉伸模量。在所有三个测试中都检测到防水性的增加。通过增加塑料含量，观察到负面影响，例如拉伸模量降低。当评价竹粉和塑料之间的相容性，使用偶联剂和MFC添加，注意到的耐水性，熔融流动性和拉伸模量的积极影响。我们还证实，用于增加竹粉和塑料之间的相容性的程序可以很容易地用于工业应用，通过改变偶联剂。总的来说，在添加MFC后观察到新的积极性质（增加的拉伸模量）和增加的耐水性。
To improve the water resistance of bamboo flour/high-density polyethylene (HDPE) composites, the effects of plastic content, coupling agents, and the addition of micro-fibrillated cellulose (MFC) on formulations were studied, and their rheological and mechanical properties were evaluated. The composites were prepared by injecting molding with a basic composition of equivalent amounts of bamboo flour and HDPE, and the melting fluidity of the compounds, tensile strength, and tensile modulus of the composites were determined. An increase in water resistance was detected in all three tests. By increasing the plastic content, negative effects such as a decreased tensile modulus were observed. When evaluating the compatibility between bamboo flour and plastic using coupling agents and MFC addition, positive effects were noted for water resistance, melting fluidity, and tensile modulus. We also confirmed that the procedure used to increase the compatibility between bamboo flour and plastic could easily be used for industrial applications by changing the coupling agents. Overall, a novel positive property (increased tensile modulus) and an increased water resistance were observed after MFC addition.
