In order to study the effect of different types of vulcanizing agents on the properties of high temperature resistant flame retardant silicone rubber, we applied four kinds of vulcanizing agents, BIPB, DCBP, BP and DCP, to rubber production, and the elongation at break of flame retardant silicone rubber, The hardness, tensile strength, and flame retardancy are compared. The results show that when the amount of vulcanizing agent used in flame retardant silicone rubber increases, the hardness of silicone rubber increases, but the elongation at break is reduced. There is no significant change in the oxygen index and tensile strength of silicone rubber.

After secondary vulcanization, compared to BIPB, DCBP, and DCP, the use of BP vulcanizing agents reduces the elongation at break and tensile strength of silicone rubber, but its hardness increases, while other vulcanization The agents all improve the tensile strength of silicone rubber. In addition, these four vulcanizing agents have improved the flame retardancy of silicone rubber to a certain extent, and further proved that different types of vulcanizing agents have a greater impact on the heat resistance of silicone rubber.
