为制备符合高速公路防眩板要求的复合材料,在毛竹粉末中添加纳米刚玉粉和烧结环氧树脂粉2种强化复合因子,制备出竹质复合材料,并对其屈服强度、吸水率、断口微观形貌、耐蚀性和耐候性进行分析。结果表明:当纳米刚玉粉和环氧树脂粉的质量分数分别为8.0%和9.8%时,竹质复合材料试件的静曲强度高达81.73 MPa,吸水率仅为0.63%,且其断口形貌组织致密,具有韧性断裂特征;试件经质量分数为10%的NaOH溶液和30%的H_2SO_4溶液浸泡168 h,均未出现起皱、鼓泡、开裂、软化、溶解等现象,达到国家标准对防眩板的耐蚀要求;试件的热失重表现优于纯竹粉温压压坯,其自由水挥发温度高达82 ℃,对高速公路在夏天高温环境...

In order to prepare the composite material that meets the requirement of anti-glare panel of highway,two kinds of reinforce composite factors,sintered epoxy resin powder and nano-corundum powder,were added into the bamboo powder to prepare the bamboo composite material,and its yield strength,water absorption rate,fracture morkhology,corrosion resistance and weather resistance were analyzed.The result show that when the content of epoxy resin powder and nano-corundum powder are 9.8% and 8% respectively,the static bending strength of bamboo compo...
