         With the rapid development of modern chemical industry and continuous improvement of technology,many new materials have been widely used in various fields.Among them,magnesium oxide has been widely applied in the adhesive industry due to its advantages of stable chemical properties,good thermal stability,good adhesion and strength.

          Taking chloroprene adhesive as an example,magnesium oxide has various functions in chloroprene adhesive,including acid absorption,pre reaction,anti scorching,and vulcanization.These functions make magnesium oxide an indispensable and important component of chloroprene adhesive,playing a crucial role in improving the performance and quality of the adhesive.

           The pre reaction of magnesium oxide with resin can effectively improve the heat resistance of the adhesive and prevent delamination and precipitation.The addition of magnesium oxide can accelerate the drying of the adhesive film,significantly improve the initial bonding force and bonding strength,and improve the transparency of the adhesive.In addition,magnesium oxide can also increase the viscosity and consistency of the adhesive,making it easier to bond and apply.Compared with other fillers,magnesium oxide has a regular shape and a smooth surface,which can be better mixed into other materials,achieving a more efficient filling effect.

            However,it is important to pay attention to the amount of magnesium oxide used.The dosage of magnesium oxide has an impact on the reaction effect and the performance of the adhesive.With the increase of magnesium oxide dosage,the high-temperature strength will be improved,but the stability of the adhesive will correspondingly decrease.But if controlled properly,it can not only effectively increase the characteristics of the adhesive,but also make it have better tensile strength and heat resistance.In some high-temperature and high-pressure environments,magnesium oxide can still maintain its stability,which can effectively increase the service life of the adhesive.Therefore,it is widely used in the preparation of high-temperature adhesives,such as in aerospace,automotive manufacturing,electronics and other fields.

            In summary,magnesium oxide has very high application value in adhesives.Magnesium oxide,as a key raw material,will play an increasingly important role in the field of adhesives.
