包含改性硫的粘结材料以及制备包含改性硫的材料的方法
摘要：
本发明提供了一种制备包含改性硫的粘结材料的方法，所述粘结材料可提供优异的阻燃性、机械强度、水密封性能和对硫氧化细菌的耐性，且可用于密封家庭和工业废物。本发明还提供了一种使用所述粘结材料、通过简单控制来制备包含改性硫的材料的方法。所述制备粘结材料的方法包括以下步骤：提供用于改性硫的原料，所述原料由100质量份硫和0.1-25质量份亚乙基降冰片烯(ENB)组成；将所述原料于120-160℃下以熔融态混合；和在所得熔融混合物于140℃下的粘度为0.050-3.0Pa·s时，将所述熔融混合物冷却至不高于120℃的温度。所述制备包含改性硫的材料的方法包括以下步骤：在制备了所述粘结材料后，将10-50％质量粘结材料与50-90％质量骨材于120-160℃下混合，同时保持所述粘结材料于140℃下的粘度为0.050-3.0Pa·s；和将所得混合物冷却至不高于120℃的温度。
摘要（英）：

A modified-sulfur-containing binder which can impart excellent ignition resistance, mechanical strength, water-barrier properties, and resistance to sulfur-oxidizing bacteria and is utilizable for sealing general and industrial wastes therewith; and a production process by which a modified-sulfur-containing material can be obtained with the binder with simple control. A process for producing the modified-sulfur-containing binder is provided which comprises: a step in which raw materials for modified sulfur comprising 100 parts by mass of sulfur and 0.1-25 parts by mass of ethylidenenorbornene(ENB) are prepared; a step in which the raw materials are melt-mixed at 120-160 DEG C; and a step in which after the viscosity at 140 DEG C of the molten mixture has reached 0.05-3.0 Pas, the molten mixture is cooled to 120 DEG C or lower. The process for producing a modified-sulfur-containing material comprises: a step in which after the binder is prepared, 10-50 mass% the binder is mixed with 50-90 mass% aggregate at a temperature of 120-160 DEG C while keeping the viscosity at 140 DEG C of the binder in the range of 0.05-3.0 Pa.s; and a step in which the mixture is cooled to 120 DEG C or lower.
