The most commonly used flame-retardant conveyor belt is in coal mines. The product features a strong belt body, low elongation, and impact and tear resistance.

The product structure is divided into PVC type and PVG type, both of which are whole core flame-retardant conveyor belts with rubber surface. The execution standard of the product is MT914-2002.

The product performance of PVG belts is suitable for conveying materials in environments with inclination angles below 20 degrees, while PVC flame-retardant conveyor belts are suitable for conveying materials in environments with inclination angles below 16 degrees.

The PVG belt has strong belt body quality and a complete range of product types and models. It is distinguished according to the rubber surface of the product and the material of the belt. The execution standard for the whole core flame-retardant conveyor belt is MT/914-2008.

Flame retardant principle

The processing and production of the belt use flame-retardant rubber products, and the laminated flame-retardant PVG conveyor belt adhesive flame-retardant system uses a combination of antimony trioxide, chlorinated paraffin, zinc borate, and aluminum hydroxide. Natural rubber and styrene butadiene rubber are prone to flame retardancy. In order to achieve better flame retardancy, they exhibit strong flame retardant effects when used in combination with chlorinated compounds. The surface material of the belt, antimony trioxide and chloride containing compounds, can exert their characteristics when transporting flammable materials. Volatile antimony chloride and antimony oxychloride have good effects.

Its material can absorb a certain amount of heat when it evaporates, and the generated gas can serve to isolate oxygen and flush combustibles. Chlorinated paraffin on the surface of the body: flame retardant. The combination of chlorine atoms produced by the decomposition of chlorinated paraffin at high temperatures and polymers produces hydrogen chloride, which reacts with highly active hydroxyl radicals or hydrogen atoms to produce water, breaking the process of oxygen and slowing down combustion until it stops. Therefore, flame retardants and carbon black are added to meet the requirements of flame retardancy.
