Azufre modificado
Un azufre modificado que comprende azufre y un organosilano que contiene polisulfuro en una cantidad en el intervalo de 0,3 a 25% en peso basándose en el peso de azufre, en cuyo azufre modificado la cantidad combinada de azufre y organosilano que contiene polisulfuro alcanza el intervalo de 90 a 100% en peso del azufre modificado obtenido y en donde el organosilano que contiene polisulfuro tiene la fórmula molecular general: (X3Si)mH(2n+1-m)Cn-Sa-Cn'H(2n'+1-m')(SiX'3)m' (1) en donde a es un número entero en el intervalo de 2 a 8, X y X' son cada uno, independientemente, un grupo hidrolizable, n y n' son cada uno, independientemente, un número entero en el intervalo de 1 a 4, y m y m' son cada uno, independientemente, un número entero en el intervalo de 1 a (2n + 1).
The invention provides modified sulphur comprising sulphur and a polysulphide-containing organosilane in an amount of in the range of from 0.3 to 25 wt % based on the weight of sulphur, in which modified sulphur the combined amount of sulphur and polysulphide-containing organosilane make up in the range of from 90 to 100 wt % of the obtained modified sulphur and wherein the polysulphide-containing organosilane is of the general molecular formula (1): (X3Si)mH(2n+1−m)Cn-Sa-Cn′H(2n′+1−m′)(SiX′3)m′; wherein a is an integer in the range of from 2 to 8, X and X′ each are, independently, a hydrolysable group, n and n′ each are, independently, an integer in the range of from 1 to 4, and m and m′ each are, independently, an integer in the range of from 1 to (2n+1). The invention further provides a process for preparing such modified sulphur, a sulphur cement product comprising the modified sulphur and a process for preparing such.
