采用室温硫化(RTV)硅橡胶粘结剂作氨气缓释材料骨架,采用碳酸氢铵作为释放氨气的活性物质并将其分散到硅橡胶骨架中,再添加补强剂气相SiO2改变硅橡胶的结构以改善其性能。观察气相SiO2的形貌,考察气相SiO2对氨气缓释材料力学性能、缓释性能等的影响。室温下,当补强剂加入量为2.5 g、捏合时间大于或等于1h时,所制得的缓释材料的力学性能最好,邵尔硬度和拉伸强度分别达到60°和1.59 MPa。 A room temperature curing (RTV) silicone rubber adhesive was used as a framework for the ammonia release material. Ammonium bicarbonate was used as an active material to release ammonia and dispersed into a silicone rubber skeleton. Then, a reinforcing agent was added to change the silicon rubber Structure to improve its performance. The morphology of the gas phase SiO2 was observed, and the influence of the gas phase SiO2 on the mechanical properties and sustained-release properties of the ammonia sustained-release material was investigated. At room temperature, when the amount of the reinforcing agent is 2.5 g and the kneading time is greater than or equal to 1 h, the mechanical properties of the sustained-release material are best, and the Shore hardness and tensile strength reach 60 ° and 1.59 MPa, respectively.
