摘　　要：为了进一步提高建筑装饰用氰酸酯树脂的力学性能,采用石墨烯(KNG-G5)改性氰酸酯树脂(CE),研究不同石墨烯添加量对氰酸酯树脂材料性能的影响。研究结果表明:当剪切速率>1 s-1时,纯氰酸酯进入了稳定的黏性区间。随着GNPs的加入,试样黏性迅速增大,体系黏度降低,并出现了明显的稀化现象。随着GNPs添加量的增加,材料拉伸强度和断裂延伸率下降,力学强度上升。当GNPs添加量为10%时,试样拉伸强度和拉伸模量比纯氰酸降低了12.5%,拉伸模量则增加了16.46%,试样截面处出现了一个较大范围的凹痕,具有优异的承载性能。In order to further improve the mechanical properties of cyanate resin for architectural decoration,graphene(KNG-G5)was used to modify cyanate resin(CE).The effects of different graphene content on the properties of cyanate resin were studied.The results showed that the pure cyanate entered a definite viscosity interval when the shear rate was greater than 1 s-1.With the addition of GNPs,the viscosity of the sample increases rapidly,and the viscosity of the system decreases and obviously dilute.With the increase of GNPs,the tensile strength and fracture elongation of the material decreased,and the mechanical strength increased.When the GNPs content is 10%,the tensile strength and tensile modulus of the sample are reduced by 12.5%and the tensile modulus is increased by 16.46%compared with that of pure cyanic acid.A large range of dents appear at the cross section of the sample,showing excellent bearing performance.This research is helpful to improve the service life of polymer materials for building decoration and has a high energy saving effect.
