摘　　要：氮化硼(BN)因其优异的导热性和化学稳定性成为提高复合材料热传导性能的理想填料,而丙烯酸酯胶粘剂尽管存在诸多优点,但热传导性能相对较差、不耐高温,从而限制了其在高温环境下的应用。本文在丙烯酸酯胶粘剂中引入导热填料氮化硼,通过制备工艺简单的方法——直接热压法制备了丙烯酸酯胶粘剂基氮化硼/松木粉末复合板(BN/SMF复合板)。研究了氮化硼用量对BN/SMF复合板导热性能、硬度、抗冲击性能以及阻燃等性能的影响。研究结果表明:(1)傅里叶变换红外光谱测试表明,丙烯酸酯胶粘剂固化反应完全。(2)随着氮化硼用量增加,BN/SMF复合板的导热系数也相应增加。(3)无机成分氮化硼在高温下不易分解,且能起到很好的物理阻隔作用,提高了BN/SMF复合板的分解温度。(4)随着氮化硼用量的增加,BN/SMF复合板的冲击强度和硬度都会增加。但当氮化硼用量达到一定值时,由于粒子团聚,破坏了复合基体的连续性,冲击强度和硬度都下降。(5)随着氮化硼用量增加,BN/SMF复合板的热传导性能、阻燃性能均有所提高。Boron nitride(BN),due to its excellent thermal conductivity and chemical stability,has become an ideal filler for enhancing the thermal conductivity of composite materials.Although acrylate adhesive has many advantages,it has relatively poor thermal conductivity and is not resistant to high temperature,which restricts its application in high-temperature environment.In this paper,the thermally conductive filler boron nitride was introduced into the acrylate adhesive,and the acrylate adhesive-based boron nitride/pine wood powder composite panels(BN/SMF composite panels)were prepared by the simple preparation process,namely the direct hot pressing method.The effects of the amount of boron nitride on the thermal conductivity,hardness,impact resistance,and flame retardancy of BN/SMF composite panels were studied.The research results showed that,(1)Fourier transform infrared spectroscopy testing indicated that the curing reaction of acrylate adhesive was complete.(2)With the increase in the amount of boron nitride,the thermal conductivity coefficient of BN/SMF composite panels also increased accordingly(.3)The inorganic component boron nitride was not easy to decompose at high temperature and could play an excellent physical barrier role,thus increasing the decomposition temperature of BN/SMF composite panels.(4)As the amount of boron nitride increased,the impact strength and hardness of BN/SMF composite panels increased.However,when the amount of boron nitride reached a certain value,due to the agglomeration of particles,the continuity of the composite matrix was disrupted,and both the impact strength and hardness decreased(.5)With the increase in the amount of boron nitride,both the thermal conductivity and flame retardancy of BN/SMF composite panels were improved.
