Magnesium Oxide Used in Adhesive

   The active magnesium oxide is one of the important raw material of chloroprene rubber adhesive agent. The activity of magnesium oxide reflects the reaction capacity between magnesium oxide and chloroprene rubber adhesive agent. The activity of active magnesium oxide is usually presented by iodine absorption value(mgT2lg). It is low activity when the iodine absorption value is lower than 40(mgIz/g). The middle activity is between 40 to 100 of the iodine absorption value. When the iodine absorption value is higher than I0, it is the high activity. Generally speaking, the high quality neoprene adhesive needs magnesium oxide with high activity.

   The polychloroprene adhesive is an important type in fluoro rubber adhesive with large production and extensive use. It has many advantages, such as large initial adhesion, high bonding strength, flexible adhesive layer and good elasticity. What’s more, it has impact resistance, water resistance, oil resistivity, alkali resistance, acid resistance and solvent resistance. Of course, it has good anti-ozone, ageing resistant, durability and fire resistance. Therefore, it can bond many metal material and non-metallic material. For example, it can be used to bond rubber, leather, fabric, artificial leather, wood, beton, asbestos and so on. It is especially appropriate for the bonding between above materials and different materials like metal, plastic and so on. In addition, it has three types. There are solvent type, emulsion type and non-solvent type. Among the three, the solvent type of chloroprene rubber adhesive agent has the widest applications. And the he solvent type of chloroprene rubber adhesive agent can be divided into heat curing type and cold bonding type. At present, the most widely-used neoprene adhesive is solvent and cold bonding type adhesive.

   Meishen Technology is a professional magnesium oxide manufacturer which can produce various of magnesium oxide. The special magnesium oxide used in adhesive is one of the brand magnesia in the company. The market share of it is more than 90%. The market share in rubber and cable industry is always more than 80% in Shandong, Hebei,Shanghai, Jiangsu and other industries. From 1995 to 2006, this company, which is a famous brand in magnesium salt industry, leads the light magneisum oxide and active magnesium oxide market used in domestic adhesive industry.
