When the dosage of magnesium oxide is below 200, the thermal conductivity and tensile strength of the silicone rubber filled with magnesium oxide with small particle size are greater than that of the silicone rubber filled with magnesium oxide with large particle size.

On the other hand, the elongation at break of silicone rubber is contrary to the maximum l of the thermal conductivity of silicone rubber when the ratio of mg //I particle size is 100/100. The addition of an appropriate amount of silane coupling agent is conducive to improving the thermal conductivity of silicone rubber, and the optimal dosage is about 0.5% of the dosage of mg //I particle size.

The heat-conducting filler is alumina or mixed particles of alumina, magnesium oxide and boron nitride, with good heat-conducting and insulating properties. Due to its flexibility, it can be closely fitted between power devices and heat-dissipating aluminum/copper sheet or machine shell, thus achieving good heat conduction and heat dissipation. At present, it has been directly used in microprocessors, DC converters, relays, UPS, automotive electronics, projection lamps and other electronic products.

At present, more research and good thermal conductivity and insulation properties of thermal insulation rubber packing aluminum oxide, silicon nitride, etc. The thermal conductivity of magnesium oxide is slightly better than that of alumina and the rubber pad with higher thermal conductivity can be prepared.

As an excellent thermal insulating rubber packing, its electrical properties are inferior to alumina, but it still meets the requirements of insulating rubber packing for common electronic and electrical products. This work USES mixed silicone rubber as the matrix and magnesium oxide as the thermal conductive filler to prepare the flexible thermal conductive adhesive pad, and its properties are studied.

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.
