Embodiment 1
[0038] First, mix and grind 1 part of azodicarbonamide, 0.6 part of benzenesulfonyl hydrazide and 0.6 part of sodium bicarbonate to more than 600 meshes to become special foaming additives, then mix 100 parts of polyvinyl chloride resin, 2 parts of dilauric acid Put di-n-butyltin, 70 parts of bis(2-ethylene)ethyl phthalate, 1 part of simethicone, 12 parts of calcium carbonate and ground foaming additives into a high-speed mixer and mix for 3 minutes. Unloading; then put the mixed material into the internal mixer, masticate for 2 minutes at 175°C, and then put it into a double-roller plastic mixer with a constant temperature of 160°C to form a molten sheet; put the molten sheet into Carry out calender molding on the calender, and combine the substrate of the gluing machine (auxiliary machine) to form a rubber cloth; foam the formed rubber cloth through a foaming furnace at 195°C for 1 minute; the foamed rubber cloth is surface modified, rolled and obtained the final product. T...
Embodiment 2
[0040] First, mix and grind 2 parts of azodicarbonamide, 3 parts of 4,4'-oxobisbenzenesulfonyl hydrazide, and 20 parts of calcium oxide to a size above 600 mesh to become a special foaming additive, and then mix 100 parts of polyvinyl chloride Resin, 3 parts of di-n-butyltin dilaurate, 70 parts of di(2-ethylene) ethyl phthalate, 10 parts of diisooctyl azelate, 2 parts of ethyl silicone oil, 15 parts of kaolin and ground hair Put the special foam additive into the high-speed mixer, mix for 3.5 minutes, and unload; then put the mixed material into the internal mixer, masticate at 160°C for 2.5 minutes, and then put it into a double-roller masticator with a constant temperature of 150°C Make it form a molten sheet material; calender the molten sheet material on a calender, and combine it with the substrate of the pasting machine (auxiliary machine) to form a rubber cloth; pass the formed rubber cloth through a foaming furnace at 185 ° C. Soak for 0.5 minutes; the foamed adhesive ...
Embodiment 3
[0042] First, mix and grind 2 parts of p-4,4'-oxobis(benzenesulfonylsemicarbazide), 3 parts of p-toluenesulfonyl hydrazide, 1 part of ammonium bicarbonate, 2 parts of zinc oxide, and 2 parts of stearyl alcohol to 600 mesh The above becomes a special foaming agent, and then 100 parts of polyvinyl chloride resin, 3 parts of di-n-octyltin maleate, 1 part of zinc stearate, 60 parts of bis(2-vinyl)ethyl phthalate, 20 parts Put 20 parts of diisooctyl azelate, 20 parts of calcium carbonate and ground special foaming additives into a high-speed mixer, mix for 4 minutes, and unload; then put the mixed materials into an internal mixer, and Plasticizing at 175°C for 3 minutes, and then put into a double-roller plastic mixer with a constant temperature of 170°C to form a molten sheet material; the molten sheet material is calendered on the calender, and combined with the basic paste machine (auxiliary machine) The sheet is formed into a tape; the formed tape is foamed in a foaming furnace...
