Abstract

The invention discloses a hot seam rubber tube resisting the temperature of 208 DEG C and a preparation method of the hot seam rubber tube resisting the temperature of 208 DEG C. The hot seam rubber tube comprises manufacture methods of an inner rubber tube, an outer rubber tube and a whole tube. The preparation method of the material of the inner rubber tube comprises the following steps of: weighting inner rubber raw materials of the inner rubber tube in parts by weight, plasticating chlorinated butyl rubber in an internal mixer, adding high-activity magnesium oxide, nano-zinc oxide, antiager and paraffin oil into the internal mixer for mixing, adding white carbon black, carbon black, light calcium carbonate, stearic acid and antioxygen, mixing, rubber sheet unloading and stopping, discharging rubber and vulcanizing; the preparation method of the material of the outer rubber tube comprises the following steps of: weighing raw materials of the outer rubber layer in parts by weight; plasticating ethylene-propylene diene copolymer in the internal mixer, adding high-activity magnesium oxide, nano-zinc oxide, antiager and paroline into the internal mixer for mixing, adding white carbon black, carbon black, light calcium carbonate, stearic acid and antioxygen for mixing, adding a vulcanizing agent, an accelerant and iron oxide red, rubber sheet unloading and stopping, and discharging rubber; and preparing the inner rubber layer and outer rubber layer of the inner rubber tube, and then preparing the hot seam rubber tube resisting the temperature of 208 DEG C.

Description

technical field [0001] The invention relates to a rubber hose, in particular to a rubber hose suitable for 208°C hot steam, and also to a preparation method of the rubber hose. Background technique [0002] At present, most of the rubber hoses for transporting steam or high-temperature water or oil are suitable for high temperatures of 100-170°C, and no matter how high the temperature is, they cannot adapt. Moreover, the research on using chlorinated butyl rubber as the main material to manufacture and transport 208°C hot steam rubber hose has always been a blank in the rubber application industry. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a 208°C heat-steam-resistant rubber hose and its preparation method. The present invention provides a 208°C heat-steam-resistant inner glue formula and outer glue formula design and a rubber hose skeleton layer design, and then Developed into a heat-resista...
