Problems solved by technology

[0003] At present, the rubber used for steel wire braided hoses generally adopts neoprene, nitrile rubber or styrene-butadiene rubber. , but the aging resistance and ozone resistance are not very good. Some of the hoses with very strict requirements use EPDM rubber, but the cost is relatively high

Embodiment 1

[0037] Chlorinated polyethylene rubber composition formula:

[0038]

[0039] The method for preparing the chlorinated polyethylene rubber that steel wire braided rubber hose is used is:

[0040] Firstly, weigh the chlorinated polyethylene rubber and various additives according to the formula, put the additives except vulcanizing agent and sulfur and the weighed chlorinated polyethylene rubber into the internal mixer at 60°C, and pass through The cooling water controls the rubber mixing temperature not to exceed 85°C. After 4 minutes of rubber mixing, add vulcanizing agent and sulfur and mix for about 2 minutes to discharge the material. Make 4~5 triangle bags on the open mill and then release the rubber and park it for later use. First preheat the rubber material to 55°C, extrude the hose under the condition that the temperature of the extruder body is 60°C, and the temperature of the head is 80°C. The rubber hose coated with the outer material is wrapped with water cloth...

[0050] The method for preparing the chlorinated polyethylene rubber that steel wire braided rubber hose is used is:

[0051] Firstly, weigh the chlorinated polyethylene rubber and various additives according to the formula, put the additives except vulcanizing agent and sulfur and the weighed chlorinated polyethylene rubber into the internal mixer at 55°C, and pass through The cooling water controls the rubber mixing temperature not to exceed 85°C. After 3 minutes of rubber mixing, add vulcanizing agent and sulfur and mix for about 3 minutes to discharge the material. Make 4~5 triangle bags on the open mill and then release the rubber and park it for later use. Put the rubber material into the extruder to extrude the rubber hose. The temperature from the feed port to the fuselage is 70°C, and the temperature of the die is 75°C. The rubber hose coated with the outer material is wrapped with water cloth by a water cloth wrapping machine, and sent to a steam vulcaniza...

Abstract

The present invention discloses a chlorinated polyethylene rubber composition, which comprises, by weight, 100 parts of rubber type chlorinated polyethylene, 8-10 parts of magnesium oxide, 3-5 parts of calcium stearate, 0.5-1 part of poly(1,2-dihydro-2,2,4-trimethyl-quinoline), 0.5-1 part of 4010Na, 40-50 parts of fast extruding carbon black / or whit carbon black, 1-2 parts of stearic acid, 10-20 parts of Stron Wi, 7-15 parts of dioctyl phthalate, 7-10 parts of an adhesive, 4-4.5 parts of a sulfurization agent, and 0.2-0.4 part of sulfur. The chlorinated polyethylene rubber prepared from the composition has characteristics of good aging resistance, good ozone resistance, good liquid resistance, and other good mechanical properties.

Description

technical field [0001] The invention relates to a chlorinated polyethylene rubber composition, in particular to a chlorinated polyethylene composition for preparing rubber hoses, and more specifically to a chlorinated polyethylene composition for steel wire braided rubber hoses. Background technique [0002] Chlorinated polyethylene rubber is used in many fields, and in different application fields, there are different requirements for the properties of chlorinated polyethylene rubber. For steel wire braided rubber hose, the structural inner rubber layer, middle rubber layer, I or II or III steel wire braided reinforcement layer, outer rubber layer, the rubber used for the inner rubber layer must at least have liquid resistance, and the outer rubber layer The rubber needs to have excellent properties such as weather resistance. Steel wire reinforced hydraulic rubber hose is mainly used for mine hydraulic support and oil field mining, suitable for engineering construction, l...
