改性硫和包含改性硫作为粘合剂的产品
摘要：
本发明提供一种改性硫，其包含硫和基于硫的重量计0.3-25wt％的含多硫化物的有机硅烷，在所述改性硫中，硫和含多硫化物的有机硅烷的组合量占所得改性硫的90-100wt％，和其中所述含多硫化物的有机硅烷具有如下分子通式(1)：(X3Si)mH(2n+1-m)Cn-Sa-Cn′H(2n′+1-m′)(SiX′3)m′，其中a为2-8的整数，X和X′各自独立地为可水解基团，n和n′各自独立地为1-4的整数，和m和m′各自独立地为1至(2n+1)的整数。本发明还提供制备所述改性硫的方法、包含所述改性硫的硫磺水泥产品以及制备所述硫磺水泥产品的方法。
摘要（英）：

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.
