Nano magnesium oxide is a kind of magnesium oxide product with extremely high content. Nano magnesium oxide has obvious small size effect, surface effect, quantum size effect and macro tunnel effect. After modification, there is no agglomeration phenomenon. It has many special functions and important application value in optics, catalysis, magnetism, mechanics, chemical industry, etc.
Nano magnesium oxide has been perfectly applied in coatings, mainly including interior walls, exterior walls, primers, etc. Because of the integration of nano magnesium oxide technology, the product performance has been greatly improved. Because it has amphiphilicity, does not stick to oil, has strong adhesion and elasticity, has a service life of more than ten years, and has unique self-cleaning function and air purification.
Nano magnesium oxide has a broad prospect and is also a new material in the 21st century. It is widely used in ceramics, oil products, coatings and other fields. Different industries have different effects. It can be used as a flame retardant in the chemical fiber and plastic industries. In the textile industry, it plays the role of a flame retardant. With the increasing demand for high-performance flame retardant and avant-garde fire prevention, it is an ideal material for fire retardant coatings.
Specific applications of nano magnesium oxide in coatings:
1. Fire retardant coatings:
Nano magnesium oxide is used in fire retardant coatings to improve the fire resistance and flame retardancy of the coating. It can block the spread of heat and release water vapor to absorb heat.
2. High temperature coatings:
Nano magnesium oxide is used in high temperature coatings to protect metal surfaces from high temperature damage. It can withstand extreme temperatures and prevent oxidation and corrosion.
3. Anti-ultraviolet coatings:
Nano magnesium oxide is used in anti-ultraviolet coatings to protect coatings from sunlight damage. It can reflect ultraviolet rays and prevent coatings from discoloration, fading and cracking.
4. Anti-corrosion coatings:
Nano magnesium oxide is used in anti-corrosion coatings to protect metal and concrete surfaces from corrosion. It can neutralize acidic substances and form a dense protective layer.
5. Anti-fouling coatings:
Nano magnesium oxide is used in anti-fouling coatings to prevent the growth of microorganisms on the surface of the coating. It can release alkaline ions to inhibit the reproduction of microorganisms.
6. Wear-resistant coatings:
Nano magnesium oxide is used in wear-resistant coatings to improve the hardness and wear resistance of the coating. It can enhance the coating’s scratch and impact resistance.
7. Barrier coatings:
Nano magnesium oxide is used in barrier coatings to block moisture and gas from penetrating the coating. It can form a dense, porous protective layer to prevent penetration damage.
