Rubber coated anchor chain, and preparation method thereof

Abstract

The invention provides a rubber coated anchor chain, and a preparation method thereof. The rubber coated anchor chain is composed of a anchor chain skeleton prepared from metal and a rubber coating layer; the anchor chain skeleton is of an iron solid structure; the periphery of the anchor chain skeleton is provided with a plurality of strip-shaped grooves; the width of each strip-shaped groove ranges from 3 to 15mm, and the depth ranges from 3 to 9mm; and the anchor chain skeleton is coated by the rubber coating layer. The surface of the anchor chain skeleton is coated with the rubber coatinglayer, so that the anchor chain skeleton can be protected effectively, surface corrosion and damage are avoided, the service life is prolonged, and damages on clamping plates and anchor gears in usingprocess of the rubber coated anchor chain are reduced; the surface of the anchor chain skeleton is provided with the grooves, so that the basic area of the anchor chain skeleton with relative to therubber coating layer is enlarged greatly; the coating firmness of the rubber coating layer on the anchor chain skeleton is increased; and in addition, a resin adhesive layer is adopted, so that the rubber coating layer is glued onto the anchor chain skeleton effectively, and local shedding and swelling are avoided.

Description

technical field [0001] The invention relates to a rubber-coated anchor chain and a preparation method thereof, in particular to a rubber-coated anchor chain with a rubber coating and a preparation method thereof. Background technique [0002] As a common shipbuilding industry product, anchor chain has a long history of use. Since the anchor chain needs to be used and placed in a humid environment for a long time, its oxidation and corrosion problems are major problems that plague the entire industry. The usual solution to the existing technology is to improve metal materials, and use a large number of alloys or replace them. Iron that is easy to rust, although the use of this kind of metal to make anchor chains solves the problem of rust, but its reprocessing process is complicated and the production cost is high; another solution is to apply coating on the surface of the metal To prevent the occurrence of oxidation and corrosion, although the problem of high cost is solved...

Problems solved by technology

Since the anchor chain needs to be used and placed in a humid environment for a long time, its oxidation and corrosion problems are major problems that plague the entire industry. The usual solution to the existing technology is to improve metal materials, and use a large number of alloys or replace them. Iron that is easy to rust, although the use of this kind of metal to make anchor chains solves the problem of rust, but its reprocessing process is complicated and the production cost is high; another solution is to apply coating on the surface of the metal To prevent the occurrence of oxidation and corrosion, although the problem of high cost is solved, the coating and metal often have the problem of adhesion, and the adhesion effect is poor, and because the anchor chain will continue to occur internally and externally during use and placement. The friction of the coating is easy to damage, resulting in a decline in the protective effect. Corrosion will first occur in the damage of the coating, and then cause damage to the coating from the inside, resulting in a decrease in the resistance of the entire chain.

In addition, the anchor chain is shaken by sea water or ships all the year round, and the links of the anchor chain collide with each other, causing friction, which exposes the metal to the outside, and the metal is more likely to rust and oxidize under the immersion in seawater; the links of the anchor chain move with each other , produce friction, and go round and round, the diameter of the anchor chain will be reduced, the tensile strength will be reduced, and its service life will be shortened
