Problems solved by technology

[0002] According to the problems found in the production process and market surveys in recent years, the current performance of steel wire braided / wound hydraulic hoses is insufficient, resulting in poor pulse performance of the finished hydraulic hoses, which are prone to phenomena such as non-sticking of the outer glue, bubbling, and appearance cracks, especially in the cold Areas, due to the poor low temperature resistance of the rubber hose, it seriously affects the normal use of the product
Patent CN201310753223.0 discloses a cold-resistant chlorohydrin rubber composition, whose low-temperature resistance reaches minus 30°C, but it still cannot meet the demand in some extremely cold regions with lower temperatures

Abstract

The invention discloses an ultralow-temperature woven / wound outer rubber mixed material for hydraulic rubber hoses, which is prepared from polyvinyl chloride, butyronitrile 26, neoprene 322, chlorinated polyethylene, sulfur, zinc oxide, stearic acid, magnesium oxide, an accelerator DM, microcrystalline wax, coumarone, high-wear-resistance carbon black, semi-reinforcing carbon black, white carbon black, argil, an anti-aging agent, dioctyl decanedioate, dibutoxyethyl adipate, an adhesive AS-88 and an anti-aging agent 4010NA. The outer rubber for hydraulic rubber tubes can greatly enhance the ultralow-temperature freezing resistance and aging resistance of the hydraulic rubber tube, increase the number of times of pulses in the product use process, lower the permanent deformation in the use process, avoid generating the phenomena of pinholes, liquid leakage and cracking in the use process and prolong the service life of the hydraulic rubber tube in an ultralow temperature environment; the low-temperature freezing resistance can reach -45 DEG C; and thus, the outer rubber is suitable for extremely cold regions.

Description

technical field [0001] The invention belongs to the field of rubber materials, in particular to an outer rubber mixed material for ultra-low temperature weaving / winding hydraulic rubber hoses. Background technique [0002] According to the problems found in the production process and market surveys in recent years, the current performance of steel wire braided / wound hydraulic hoses is insufficient, resulting in poor pulse performance of the finished hydraulic hoses, which are prone to phenomena such as non-sticking of the outer glue, bubbling, and appearance cracks, especially in the cold In regions, due to the poor low temperature resistance of the rubber hose, it seriously affects the normal use of the product. Patent CN201310753223.0 discloses a cold-resistant chlorohydrin rubber composition, whose low-temperature resistance reaches minus 30°C, but it still cannot meet the demand in some extremely cold regions with lower temperatures.
