摘要
根据纳米碳酸钙的特点及填充补强机理，将白燕华ＣＣ填充于ＮＲ，ＳＢＲ及ＢＲ胶料中，测试其补强填充效果。结果表明，随白燕华ＣＣ用量的增大，ＢＲ和ＳＢＲ胶料的拉伸强度明显上升，而ＮＲ胶料则表现为先缓慢上升，在白燕华ＣＣ用量大于６０份后明显下降；ＳＢＲ和ＢＲ胶料的撕裂强度则不如ＮＲ胶料增长显著。在ＳＢＲ和ＢＲ胶料中随白燕华ＣＣ用量的增大，硫化时间明显缩短。纳米碳酸钙可部分或大部分替代炭黑和白炭黑作补强填料，具有填充量大，补强、增白效果好等特点，适宜在浅色橡胶制品中应用。
The reinforcing effect of Calcene CC in NR,SBR or BR was determined.The results showed that the tensile strength of BR or SBR compounds increased remarkably as the level of Calcene CC increased;the tensile strength of NR compound increased slowly at first as the level of Calcene CC increased,but started to decrease significantly as the level of Calcene CC increased to 60 phr;the tear strength of NR compound improved more significantly than that of SBR or BR compounds.The curing cycle shortened significantly as the level of Calcene CC in SBR or BR compounds increased.Nano calcium carbonate could be used as reinforcing filler partly instead of carbon black or silica,and it featured higher loading level,better reinforcing and whitening effects,and was suitable to be used in the light color rubber products.
