- Abstract
The dealcoholized room temperature vulcanized (RTV-1) silicone sealant was prepared with α, ω-dihydroxy-polydimethylsiloxane as the base rubber, and fillers, crosslinking agents, coupling agents, and self-made titanium complex catalysts. The influence of the types of titanium complex catalyst on the viscosity, vulcanization rate, and mechanical properties of the sealant was investigated. The results show that compared to the primary titanium catalyst complex, the dealcoholized RTV-1 silicone sealant is not thicken significantly with the secondary titanium complexes. Instead, it has a higher the vulcanization rate, tensile strength, elongation at break, and storage stability. It has 8 minutes of surface drying time, the curing depth of 4. 9 mm after 24 hours, the tensile strength of 1.30 MPa, the elongation at break of 335%, and it also has the same surface drying time when cured at 65°C for 7 days in accelerated aging, and the mechanical performance retention rate is higher than 90%, showing good performance.
