As the foundation of the automobile industry, auto parts are a necessary factor to support the sustainable and healthy development of the automobile industry. In particular, the current independent development and innovation in the auto industry, which is in full swing, requires a strong component system to support it. Hebei Messi Biology Co., Ltd. will briefly introduce the application of magnesium oxide in auto parts.
Tires: With the increase of the rubber content of the rubber material, in order to ensure the hardness of the bead steel wire rubber, the amount of carbon black must be increased, which brings great difficulties to the mixing process of the rubber material, and the power consumption during mixing is greatly increased Increase, the temperature of the rubber material rises quickly, and it is easy to scorch. Magnesium oxide mainly plays the role of anti-scorch agent, vulcanization accelerator, acid absorbing agent, high temperature resistance, fire prevention and flame retardant in tires. Magnesium oxide has the effect of inhibiting the reaction between sulfur and rubber, so that the content of free sulfur in the rubber can be kept relatively high, thereby improving the adhesive performance of the rubber and the safety performance of mixing and processing. Hebei Meixi Biological Co., Ltd. conducted a test on the application of magnesium oxide in the bead wire rubber of heavy-duty bias tires, and achieved good results.
Engine oil emulsifier: Magnesium oxide can prevent the fusion of emulsified cores and stabilize the emulsion. Antioxidant magnesium can accelerate the separation of oil and water, prevent the gradual formation of pigments in the emulsion, thereby preventing or slowing down the leakage of aluminum.
Brake pads: Magnesium oxide in brake pads can increase the decomposition temperature of the resin, thereby reducing thermal decay, thereby stabilizing the friction coefficient, improving the compactness of friction materials, and reducing tacit calculations. At the same time, it can improve the wear resistance and high temperature resistance of the friction material, increase its toughness, make the product more stable, and make the brake noise smaller.
