Polymer noctilucent rubber fender

Abstract

A macromolecule rubber fender includes a macromolecule strength rubber fender body which is a hollow or solid type; at least one of the materials of 5 to 24kg of natural rubber, 5 to 24kg of styrene-butadiene rubber, 5 to 24kg of 3-polybutadiene rubber and 4 to 18kg of polyurethane rubber, and 3 to 5kg of carboform reinforcing materials CF, 5 to 10kg of the polyester fiber or nylon fiber of a macromolecule reinforcing material, 6 to 12kg of Haloflex, 3 to 4.5kg of zinc oxide, 1 to 1.5kg of stearic acid, 20 to 24kg of calcium bicarbonate, 28 to 35kg of carbon soot, 0.4 to 0.8kg of coumarone, 3 to 5kg of pine tar, 0.9 to 1.5kg of sulphur powder, 0.8 to 1.2kg of accelerant DM or 0.3 kg of accelerant D, 0.6 to 1.0kg of age inhibitors RD or 1.0 to 1.5kg of age inhibitors D are uniformly mixed and smelted, shaped by a die and then are vulcanized by a known vulcanization technique, thus obtaining the finished product. Compared with the prior art, the macromolecule rubber fender has the advantages of high bounce, corrosion resistance, high anti-impact force, uneasy aging, no cracking, long service life, and the like. Besides, the macromolecule rubber fender is adaptive to the fenders with various shapes.

Description

technical field [0001] The invention relates to an anti-collision device, in particular to a rubber fender suitable for ships and docks, and between ships. Background technique [0002] In order to prevent ships or wharf buildings from being damaged, it is necessary to install fender protection equipment between ships and wharfs, and between ships and ships. Traditional fenders generally use wooden piles, planks, old pneumatic tires, etc. With the modern ship With the development of the wharf, the traditional simple fenders have been replaced by rubber fenders, and have become excellent anti-collision equipment for wharf ships. The rubber fenders are fixed on the docks and docks with iron chains or bolts when in use to ensure the safety of operations when the ship is berthing or moving. At present, most of the rubber fenders at home and abroad are made of pure rubber, and their internal structures have not changed. , there are defects such as small compression deformation, ...

[0002] In order to prevent ships or wharf buildings from being damaged, it is necessary to install fender protection equipment between ships and wharfs, and between ships and ships. Traditional fenders generally use wooden piles, planks, old pneumatic tires, etc. With the modern ship With the development of the wharf, the traditional simple fenders have been replaced by rubber fenders, and have become excellent anti-collision equipment for wharf ships. The rubber fenders are fixed on the docks and docks with iron chains or bolts when in use to ensure the safety of operations when the ship is berthing or moving. At present, most of the rubber fenders at home and abroad are made of pure rubber, and their internal structures have not changed. , there are defects such as small compression deformation, high reaction force, low energy absorption, easy aging, poor anti-collision force, easy breakage, and short service life. When the ship is berthing or moving, the compression deformation generated by the fender cannot follow The movement of the hull rotates, so the shear force and friction are very large, which often damage the iron chains, bolts and other joints that fix the fender, and the paint on the hull is often scraped or damaged, which not only affects the operation and safety of the ship. , and it is also very difficult to replace and maintain, which cannot meet the needs of modern docks and shipyards.
