Abstract

The present invention is one kind of large rubber ship fender and its making process. The technological scheme of the present invention is that the hollow conic rubber ship fender has built-in nuts and steel plate skeleton in the front plane and holes for screws in the back plane. The hollow conic rubber ship fender is made through the following steps: 1. cutting steel plate, sanding to derust, brushing metal adhesive and coating the steel plate with rubber; 2. mixing raw rubber 50-58 wt%, vulcanization accelerator 2-2.6 wt%, carbon black 35-50 wt%, softening agent 3-5 wt% and antiager 2-3 wt%; and 3. co-extruding the mixture obtained in the step 2 and the skeleton steel plate obtained in the step 1, vulcanizing, demolding and trimming. The present invention is applied for guarding berth and ship, and has high stiffness, high bending and shearing strength, high corrosion resistance and other advantages.

Description

Technical field: [0001] The invention belongs to a rubber fender and a manufacturing method thereof, in particular to a large-scale conical rubber fender for impact protection for berths and ships in ports and wharves and a manufacturing method thereof. Background technique: [0002] At present, in ports and wharfs, in order to prevent damage to ships and berths in ports and wharves, wooden stakes or waste tires are generally set around the outer sides of ships and berths. Obviously, wood piles are easy to waste wood and manpower for installation, and waste tires do not have good resistance to bending and shearing. Invention content: [0003] The purpose of the present invention is to propose a large-scale conical rubber fender and a technical solution for its manufacturing method to solve the problems existing in the background technology: wooden piles are easy to waste wood, and waste tires do not have good bending and shearing resistance. ability to cut. The technical...
