Problems solved by technology

Under low temperature conditions, the covering rubber of the conveyor belt tends to harden and become brittle, loses elasticity, and the surface of the conveyor belt will crack
Due to the low temperature, the adhesion between the steel wire rope and the rubber will be greatly reduced, which will seriously affect the conveying effect and service life of the belt

Embodiment 1

[0021] As shown in the drawings of the description, an oil-resistant and cold-resistant steel cord conveyor belt according to the present invention includes an upper covering rubber layer 1, a crack-resistant intermediate rubber 2, a high-adhesive core rubber 5, a steel wire rope 3 and a lower covering rubber layer 4 . Made by following steps:

[0022] 1 Mixing: The main rubber is mixed with carbon black as the main reinforcing agent, anti-aging agent, vulcanizing agent, plasticizer and other additives are mixed in a high-performance internal mixer according to the two-stage method, and the rubber is mixed in the first stage. Accelerators are added to make oil-resistant and cold-resistant rubber. The whole condition is completed under automatic conditions to ensure the uniformity and stability of rubber mixing.

[0023] 2. Calendering: The rubber compound obtained by mixing is extruded and calendered, and bonded with the skeleton material. The process strictly controls pr...

Abstract

The invention discloses an oil-resistant and cold-resistant steel wire rope core conveyer belt. The problems that an existing steel wire rope core conveyer belt is not oil-resistant, not cold-resistant and not crack-resistant are solved. The conveyer belt comprises covering adhesive layers, middle adhesive, high-adhesion core adhesive and framework materials. The framework materials are evenly distributed in the high-adhesion core adhesive, the covering adhesive layers are divided into an upper covering adhesive layer and a lower covering adhesive layer, the middle adhesive is arranged between the covering adhesive layers and the high-adhesion core adhesive, and the framework materials are steel wire ropes. The covering adhesive of the oil-resistant and cold-resistant steel wire rope core conveyer belt is good in oil-resistant and cold-resistant performance; the core adhesive is high in adhesive strength, and therefore the problem that the adhesive strength of sizing materials and the steel wire ropes is low at low temperature is solved; crack-resistant adhesive is arranged between the covering adhesive and the high-adhesion core adhesive, surface cracking is effectively prevented from spreading downwards along cracks, low-temperature air is effectively prevented from being transmitted to the high-adhesion core adhesive and the steel wire ropes, and therefore service life of the conveyer belt is prolonged.

Description

technical field [0001] The invention relates to a steel cord conveyor belt, in particular to an oil and cold resistant steel cord conveyor belt. Background technique [0002] Oil-resistant conveyor belt is a kind of special-purpose conveyor belt. It is mainly used to transport materials containing mineral oil or animal and vegetable oil. The oil-resistant belt is used in large quantities in oilfield mining, and it mainly transports a large amount of oil sand produced in the mining process. Since many oil sand production areas are located in alpine regions, the lowest temperature in winter reaches -60°C. Under low temperature conditions, the covering glue of the conveyor belt tends to harden and become brittle and loses its elasticity. Cracks will occur on the surface of the conveyor belt and the cracks will extend downward as the use time prolongs, and the conveyor belt is easy to break. Due to the low temperature, the adhesion between the steel wire rope and the rubber wil...
