The rubber roller usually uses metal as the core and the outer rubber. The rubber used in different occasions is different from that used in the rubber roller. The rubber roller used in printing equipment such as printing, printing and dyeing, chemical fiber, papermaking and textile has long been exposed to oil or aromatic hydrocarbons. Solvents, which require good oil resistance, use nitrile rubber. In recent years, many oil-resistant rubber roller manufacturers have begun to add nitrile-butadiene rubber powder to rubber-coated rubber rollers. Why? What is the role of adding nitrile rubber powder to the oil roller?
Nitrile rubber is widely used in the production of various oil resistant rubber rollers due to its good oil resistance and electrical conductivity. However, the price of nitrile rubber as the main material is high, and there will also be certain price fluctuations, nitrile rubber and various The price of rubber auxiliaries has risen. The production cost of nitrile rubber rollers is difficult to control. The raw material of nitrile rubber powder is the waste plastic nitrile rubber product with high rubber content. The price is low and the oil resistance is excellent. It is added to the oil-resistant nitrile rubber roller. Reduce the amount of nitrile rubber used as the main material in production to reduce the cost of raw rubber roller rubber.
From a performance point of view, the nitrile rubber powder has good heat resistance, cold resistance, abrasion resistance and solvent resistance, and can further improve the abrasion resistance, oil resistance, aging resistance, and ozone resistance of the oil roller, and can be improved to a certain degree. The service life of the oil roller is extended; the mesh structure of the nitrile rubber powder can change the original radial tight structure of the oil roller, and the oil roller with a loose mesh structure can not only accept various surface treatment agents, These surface treatment agents can also penetrate deeper in the surface of the roller, thereby improving the solvent resistance and adaptability of the oil-resistant roller in the oil medium or aromatic hydrocarbons.
The nitrile rubber powder itself can also improve the permanent deformation of the oil-resistant rubber roller and various physical and mechanical properties. It can be used not only in the production of rubber roller with nitrile rubber as the main material, but also to reduce raw material costs and improve the overall performance of the rubber roller. , It can also be blended with rubber rollers made of natural rubber as raw materials to improve the oil resistance and abrasion resistance of natural rubber rollers. It should be noted that the compatibility of nitrile rubber powder and natural rubber is very low, so the amount of nitrile rubber powder should not be too much.
The use of an appropriate amount of nitrile rubber powder in the oil-resistant rubber roller can not only reduce the production cost of the rubber roller, but also improve the wear resistance, oil resistance, aging resistance, ozone resistance performance of the nitrile rubber roller, and improve the rubber roller in the oil environment. The adaptability; in addition to adding nitrile rubber powder, reducing the production cost of oil roller can also be part of the nitrile rubber with nitrile rubber reclaimed rubber to reduce raw material costs.
