Colourful noctilucent rubber fender

Abstract

The invention relates to a colorful luminous rubber shipboard fender which is a semicircular hollow shipboard fender, circular hollow shipboard fender, square hollow shipboard fender or semicircular solid shipboard fender. The finished product of the colorful luminous rubber shipboard fender is prepared from raw materials including at least one of 15 to 25kg of natural rubber, 15 to 25kg of styrene-butadiene rubber and 18 to 22kg of polybutadiene rubber as well as 13 to 18kg of polyurethane rubber, 2 to 3.5kg of afterglow luminescent powder (fluorescer), 6 to 10kg of light-reflecting powder, 2.3 to 4kg of zinc oxide, 1.0 to 1.5kg of stearic acid, 0.4 to 1.0kg of coumarone, 20 to 25kg of calcium bicarbonate, 28 to 35kg of carbon black, 3 to 5kg of pine tar, 1 to 1.5kg of sulfur powder, 0.8 to 1.2kg of accelerant DM or 0.2 to 0.4kg of accelerant D, 0.6 to 1.0kg of age inhibitor RD or 1.0 to 1.5kg of age inhibitor D and 3 to 5kg of toner through even blending, mold molding and sulfuration by means of the currently known sulfuration process. Moreover, the toner can be selected according to user requirements and the top of the semicircular hollow shipboard fender has a plurality of ventholes. The colorful luminous rubber shipboard fender has ageing resistance and ideal visual sensation and can prevent unexpected collision; moreover, the shipboard fender has excellent performance, elegant appearance and the cost not higher than that of a common rubber shipboard fender.

Description

Technical field: [0001] The invention relates to a method for preparing protective rubber fenders between ships and wharves or between ships on a port wharf. Background technique: [0002] At present, seaports and wharves need to take protective measures between ships and wharves in order to prevent damage to wharves and ships due to ship impact force when ships are berthing or stopping. That is to set a pad, usually using wood blocks, waste tires and steel string protection materials. In my country, the berthing ship type and tonnage of ports and wharves are relatively complex. Large ships such as oil tankers, bulk carriers and containers need to increase the loading capacity and sailing speed of ships, thin hulls, outer drums, large displacement, deep draft and wharf construction. Pile pier structures are required and moved to the deep sea for sufficient safety, often causing the ship and wharf and liner to be bruised or seriously damaged. Due to the poor braking performa...

AI Technical Summary

Problems solved by technology

Due to the poor braking performance of small ships and the high berthing speed, the impact force of the ship often causes deformation or damage to the fender

It brings difficulties to maintenance and loading and unloading, and the existing liner has poor corrosion resistance and wear resistance, and has a short service life and needs to be replaced frequently. Although the steel widening material is durable, the disadvantage is that the hull is easily damaged, and maintenance after damage is also difficult. Very difficult

In addition, during nighttime operations, due to dead lights or insufficient lighting, poor visibility, collision accidents are prone to occur, or ships need to berth repeatedly to be accurate, which lacks both safety and accuracy
