Problems solved by technology

[0007] The purpose of the present invention is to overcome the disadvantages that the polyurethane coating used for the existing pay-off reel is easy to rub against the wire to generate heat, resulting in a decrease in the hardness of the coating, stickiness on the surface, and even tearing and peeling, which further affects the normal use of the pay-off reel. Provided are a pay-off reel, its rubber covering material and a preparation method of the rubber covering material

Abstract

The invention discloses a paying-off wheel and rubber-coating material and a preparation method of the rubber-coating material, and belongs to the rubber material and the preparation method thereof. The paying-off wheel rubber-coating material is prepared from the following components in mass percent: 50-55% of ethylene-propylene-diene monomer, 30-35% white carbon black, 1-2% of coupling agent, 4-6% coloring agent, 1-3% of paroline, 4-6% of oligomer ester, 1.5-2% of dicumyl peroxide, 1-1.5% of sulfur; the preparation step is as follows: mixing masterbatch, sulphurating the masterbatch; pre-molding; pre-curing; and post-curing. The paying-off wheel rubber-coating prepared by the invention has the advantages of being small in surface friction coefficient, good in elasticity and abrasion resistance, and large in compression modulus, and has excellent mechanical strength and good weather aging resistance.

Description

technical field [0001] The invention belongs to the technical field of rubber materials and a preparation method thereof, and more particularly relates to a material with ethylene propylene diene rubber as a matrix, which can be used for encapsulating a pay-off wheel and a preparation method thereof. Background technique [0002] As the main carrier of electric energy transmission, cables are used and laid a huge amount of work. When laying cables in the traditional power system, it mainly relies on manpower to remove the cables from the cable reels and then lay the cables, which is time-consuming and labor-intensive, and the work efficiency is low. Especially when laying large quantities of cables, a lot of human resources are often wasted. Increase the construction cost and delay the construction progress. With the continuous development of UHV technology in my country, the pay-off wheel has been widely used to pay off the cable, that is, the cable is wound on the pay-off...
