Abstract
The invention discloses a chloroprene rubber flow guide sleeve, and relates to the field of ocean towing systems. The chloroprene rubber flow guide sleeve is prepared from the following raw materials: 100 parts of chloroprene rubber, 30-55 parts of ethylene propylene dienemonomer, 6-12 parts of silane modified organic montmorillonite, 3-6 parts of a vulcanizing agent, 2-4 parts of an accelerant, 5-8 parts of an active agent, 5-12 parts of a foaming agent, 50-80 parts of a reinforcing agent, 3-8 parts of an anti-aging agent and 1-3 parts of an auxiliary agent. The vulcanizing agent is prepared from zincoxide, DCP and odorless DCP according to the weight ratio of 2: (0.5 to 0.7): (0.5 to 1.5); the accelerant is formed by compounding an accelerant ETU and an accelerant DM according to the weight ratio of 1: 1.5. The chloroprene rubber is adopted as a matrix, and formula materials such as the ethylene propylene dienemonomer and the silane modified organic montmorillonite are added for mixing and mould pressing foaming, so that the obtained chloroprene rubber flow guide sleeve has the density similar to that of seawater, high elasticity, good mechanical property, seawater resistance and wear resistance, and has excellent tear resistance, is suitable for being applied to ocean towing cables.
Description
technical field [0001] The invention belongs to the field of marine towing systems, and in particular relates to a neoprene rubber diversion sleeve and a preparation method thereof. Background technique [0002] The diversion sleeve includes the sum of all rubber parts, plastic parts, fasteners, etc. installed on the trailer; in a narrow sense, the diversion sleeve specifically refers to the streamlined rubber parts that provide diversion function (originally made of plastic, this patent is rubber material). The diversion sleeve can significantly increase the submersion depth of the underwateracoustic equipment in the towing system, reduce the resistance and flow noise of the towline, and increase the service life of the towline. [0003] Patent CN208028551U discloses an armored cable diversion sleeve structure and its loading and unloading device, which mentions that the tow cable is a common way to connect the ship and the underwater tow body, and the tow cable will gene...
