Preparation raw material of cable rubber for electric welding machine used outdoors in north

Abstract

The invention discloses a preparation raw material of cable rubber for an electric welding machine used outdoors in the north. The preparation raw material of the cable rubber for the electric welding machine used outdoors in the north is prepared from raw materials in parts by weight as follows: 40-55 parts of silicone rubber, 25-35 parts of ethylene propylene rubber, 20-32 parts of butyl rubber, 5-8 parts of zinc oxide, 1-4 parts of stearic acid, 0.5-2 parts of paraffin, 3-7 parts of an anti-aging system, 20-50 parts of a reinforcing system, 1.2-2.5 parts of sulfur and 1.5-2.5 parts of an accelerant CZ. The preparation raw material has the benefits as follows: the cable-coating rubber required by the electric welding machine used in cold environments outdoors in the north has excellent cold and hot tear resistance, excellent flex resistance and excellent wear resistance, is applicable to environments with cold and hot temperature difference changes and is a cable-coating rubber raw material capable of keeping physical performance.

Description

technical field [0001] The invention relates to a rubber raw material, in particular to a raw material for preparing cable rubber of outdoor electric welding machines in the north. Background technique [0002] The natural landscape of Northeast China shows cold and wet characteristics, and its formation and development are closely related to its geographical location. Northeast China is the region with the highest latitude in my country. It is cold in winter. Although high latitude is the basic factor, its relative location also plays a significant role. Its north and the "cold pole" of the northern hemisphere - Verkhoyansk-Oymyakon East Siberia, where it is located, is adjacent, and the cold wave from the Arctic Ocean often invades, causing the temperature to drop sharply. To the west is the Mongolian Plateau, which is as high as 1,000 meters. The Siberian polar continental air mass often strikes the northeast region directly from a high position. Therefore, the winter tem...

Problems solved by technology

[0003] The temperature in the region is cold, and there are many ice and snow affected by the climate, which is easy to accumulate on the transmission network. Because the high towers of the transmission network are mostly made of steel structures, due to the influence of low temperature and cold environment, the hardness of steel is brittle. The impact leads to cracking or even damage. If it is not repaired in time, the entire tower will collapse and cause major accidents, which will affect the operation of power transmission

[0004] In the process of repairing the high tower, the repair of the high tower requires the use of an electric welding machine to weld the cracks or fractures for repairing. However, the electric welding machine consumes a lot of electricity, which may easily cause the welding machine cable to heat up and become soft. When it is stopped, it will be affected by the ambient temperature. , the cable rapidly cools and hardens, and the integrity of the rubber covering the cable is easily damaged by thermal expansion and contraction. In order to facilitate transportation, the cable needs to be wound and stored when the electric welding machine is stored. In a low-temperature environment, the hardness of the rubber is relatively high, and it bends when winding and storing. Folding will cause the rubber to break
