Examples
Embodiment 1
[0029] The total weight is 1000 parts, add 200 parts of epoxy resin, 1 part of diethyl phthalate and 1 part of bentonite into a reaction vessel containing 598 parts of deionized water, dissolve until there is no obvious block or flake in the system Materials, and finally obtain a uniform emulsion, which is recorded as liquid A; 0.2 parts of isobutylpropylamino-POSS is dissolved in 197.8 parts of deionized water, which is recorded as liquid B. Add liquid B to liquid A dropwise, and ultrasonicate for 10 minutes while adding; then at 80°C, use a 2mm film applicator to evenly coat the paint on the surface of nitrile rubber, and finally transfer the rubber to a 100°C constant temperature drum In an air drying oven, cure and keep warm for 24 hours.
Embodiment 2
[0031] The total weight is 1000 parts, add 200 parts of epoxy resin, 1 part of diethyl phthalate and 1 part of bentonite into a reaction vessel containing 598 parts of deionized water, dissolve until there is no obvious block or flake in the system materials, and finally obtain a uniform emulsion, which is recorded as liquid A; 0.4 parts of isobutylpropylamino-POSS are dissolved in 197.6 parts of deionized water, which is recorded as liquid B. Add liquid B to liquid A dropwise, and ultrasonicate for 10 minutes while adding; then at 80°C, use a 2mm film applicator to evenly coat the paint on the surface of nitrile rubber, and finally transfer the rubber to a 100°C constant temperature drum In an air drying oven, cure and keep warm for 24 hours.
Embodiment 3
[0033]The total weight is 1000 parts, add 200 parts of epoxy resin, 1 part of diethyl phthalate and 1 part of bentonite into a reaction vessel containing 598 parts of deionized water, dissolve until there is no obvious block or flake in the system Materials, and finally obtain a uniform emulsion, which is recorded as liquid A; 0.6 parts of isobutylpropylamino-POSS is dissolved in 197.4 parts of deionized water, which is recorded as liquid B. Add liquid B to liquid A dropwise, and ultrasonicate for 10 minutes while adding; then at 80°C, use a 2mm film applicator to evenly coat the paint on the surface of nitrile rubber, and finally transfer the rubber to a 100°C constant temperature drum In an air drying oven, cure and keep warm for 24 hours.
