The effects of different brands of magnesium oxide on the vulcanization and mechanical properties of rubber and the effects of light magnesium oxide and active magnesium oxide on the vulcanization and mechanical properties of rubber were studied.

　　The results show that in CPE and CR, the maximum torque of active mGO is greater than that of light MGO. The properties of magnesium oxide with the same activity are also different in different rubber. Magnesium oxide and zinc oxide are mainly used in rubber to play a fluidity and antioxidant capacity, increase the tensile strength and impact resistance of rubber.

　　Secondly, in the vulcanization process, the reaction of zinc oxide as a surfactant with organic accelerator, stearic acid and sulfur occurs on the surface of zinc oxide particles.

　　Due to the high electron affinity of zinc oxide, the ability to adsorb accelerator is strong, under the action of stearic acid can be dissolved in the accelerator zinc salt, so as to improve its solubility, and amine or fatty acid to form a zinc complex, so that the accelerator more active.

　　Sulfur yellow added to the complex, through the induction of activation to form a strong vulcanizing agent. In this process, the surface of znO particles continuously reacts, the particle size decreases, and the zNO is consumed until the rubber is fully vulcanized.

　　Meishen is the world's leading producer of magnesium oxide, Magnesium oxide is an oxide of magnesium, an ionic compound. It is a white solid at room temperature. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. Magnesium oxide is white or light yellow powder, odorless, tasteless, this product is insoluble in water and ethanol, melting point 2852 ° C, boiling point 3600 ° C, magnesium oxide has high refractory insulation properties. It can be converted into crystal by burning at a temperature above 1000 ° C. If it rises above 1500 ° C, it will form a burnt magnesia or sintered magnesia.

　　Magnesium oxide can be used in the manufacture of metallurgy, smelting, advanced magnesia bricks, refractory materials and moisturizing materials. It is also widely used in rubber, rubber sheet, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, glass fiber reinforced plastics and Surface coating of silicon steel sheet, paper production, steel ball polishing, leather treatment, insulation materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc.

　　Hebei Meishen Chemical Technology Group is the main magnesium oxide producer in the world. It is also the largest magnesium salt producer in China and has won the ISO9002 quality system certification. It also has GMP-Certification.

　　With rich experience in the research, development, production, management and operation of magnesium oxide products, Meishen Group has always attached great importance to the research and development of new products and strict requirements on product quality. Meishen has a high-level sales team. The business covers more than 20 countries and regions around the world. It is widely welcomed by new and old customers.
