Abstract

The invention discloses a production method of an anticorrosion wear-resistant marine anchor chain. The production method includes: weighing the components, by weight, of titanium carbide, silicon oxide, copper oxide, cobalt powder, tricalcium phosphate, tungsten carbide and silicon nitride, mixing, adding the mixture into a medium-frequency heating furnace, heating in vacuum to allow melting to obtain mixed melt A; soaking carbon fiber in plant extract, refrigerating at a low temperature for 48 hours, and getting ready for use; 4, mixing maleic anhydride and phenethyl alcohol, stirring well,adding the carbon fiber treated at the low temperature and nano aluminum, charging the mixture into an extruder, and extruding master batch for use; adding the master batch into the mixed melt A, stirring, adding ethylene-propylene-diene monomer rubber and oxidized paraffin, pouring the hot mixture into an anchor chain mold with an antirust coating, and demolding after solidifying to obtain the marine anchor chain. The marine anchor chain produced via the single-step forming process is produced with the simplified process, the equipment requirement is low, and the produced marine anchor chainis good in compression resistance and corrosion resistance and rarely layers.

Description

technical field [0001] The invention relates to the field of ship anchor chain preparation, in particular to a method for preparing a corrosion-resistant and wear-resistant ship anchor chain. Background technique [0002] The anchor chain is the chain connecting the anchor and the hull or marine engineering equipment. With the continuous utilization and development of marine resources by humans, marine energy development devices such as marine mineral resource exploration and development projects, offshore tidal power stations, wave power stations, and temperature difference power stations, etc. Continuously put into use to provide new energy for human beings. These engineering structures anchored in the ocean are positioned in the sea through the marine engineering mooring anchor chain. Therefore, the marine engineering mooring anchor chain is an important outfitting piece related to the safety of marine engineering. Due to the long service life of marine engineering moori...
