摘 要:以木質(zhì)素和白泥為原料,在球磨機上以一定的轉速并按照一定的配比混合濕法球磨制備了木質(zhì)素-白泥(lignin-lime mud)復合物,并將其用于丁腈橡膠(NBR)中,通過(guò)共混制備了木質(zhì)素-白泥(lignin-lime mud/NBR)丁腈橡膠復合材料?疾炝四举|(zhì)素-白泥(lignin-lime mud)復合物配比對丁腈橡膠復合材料力學(xué)性能的影響。在確定m(木質(zhì)素)∶m(白泥)=1∶2后,研究了不同填料份數對丁腈橡膠復合材料力學(xué)性能的影響。研究結果表明:當m(木質(zhì)素)∶m(白泥)=1∶2時(shí),填料用量為120份時(shí),丁腈橡膠的力學(xué)性能較佳,其拉伸強度、 斷裂伸長(cháng)率、300%定伸應力分別達到11.1 MPa、1 403.6%、3.00 MPa。SEM實(shí)驗結果表明,木質(zhì)素-白泥復合物與橡膠之間有較好的相容性。

Abstract:The lignin-lime mud/NBR composites were prepared by mechanical blending of NBR with lignin-lime mud complex, a mixture obtained from lignin and lime mud prepared by ball-milling. The study of the ratio of lignin to lime mud, the different loadings of lignin-lime mud on the mechanical properties of the rubber composites were examined. The experimental results indicated that the comprehensive performance was obtained at lignin to lime mud ratio of 1 to 2 and lignin-lime mud loading of 120 phr; the tensile strength, the elongation at break and the 300% modulus of rubber composites were 11.1 MPa, 1 403.6% and 3.00 MPa, respectively. And the result of SEM indicated that lignin-lime mud complex had good compatibility with NBR.
Key words:NBR; lignin; lime mud; composites
