Example Embodiment
[0018] Example 1
[0019] Plasticizing and mixing 100 parts of fluororubber, 10 parts of magnesium hydroxide, 15 parts of calcium hydroxide, 3 parts of antioxidant, 5 parts of vulcanizing agent, and 30 parts of titanium dioxide to form a rubber compound;
[0020] Calendering the mixed rubber to prepare a continuous tape with a thickness of 0.15mm, the calendering temperature is 80°C, and the speed is 20m / min;
[0021] The mesh fabric is placed between two layers of rubber cloth, and drum vulcanization is performed at a temperature of 170° C. for 10 minutes, so that the calendered rubber cloth and the mesh fabric are vulcanized and bonded to form a fluororubber rubber cloth.
[0022] The fluororubber tape prepared by the above method has a thickness of 0.40mm and a weight of 550g / m 2 . The peeling fastness to the base fabric is 0.81N / m, the limiting oxygen index is 29, the breaking strength can reach 350N / 5cm, it is resistant to 98% sulfuric acid, 40% sodium hydroxide, 61% nitric acid,...
Example Embodiment
[0023] Example 2
[0024] 100 parts of fluororubber, 15 parts of calcium hydroxide, 2 parts of antioxidant, 6 parts of vulcanizing agent, and 20 parts of titanium dioxide are masticated and kneaded to form a rubber compound.
[0025] The rubber compound was calendered into a continuous rubber cloth with a thickness of 0.18mm by calendering, the calendering temperature was 80°C, and the speed was 20m / min.
[0026] Vulcanization bonding: Put the aramid mesh fabric between the two layers of fluoroelastomer tape, and vulcanize in the drum. The three layers of materials are all slightly tensioned to ensure the flatness when entering the vulcanizing equipment. The vulcanization temperature is 180°C, and the guaranteed vulcanization time is 10 minutes.
[0027] The thickness of the fluororubber tape made in this embodiment is 0.45mm, the limiting oxygen index is 36.4, the breaking strength can reach 500N / 5cm, it is resistant to 98% concentrated sulfuric acid, 40% sodium hydroxide, 60% nitric...
