Analysis of inorganic coatings alternative organic coatings

It is understood that for a long time, organic coatings have been widely used for their good decoration, variety of varieties and low prices. However, due to the fact that the raw materials for organic coatings are non-renewable materials, they are currently deficient. The main raw materials for organic architectural coatings originate from coal, petroleum, natural gas and other resources. During processing, a large amount of by-products, volatile solvents, and excess monomers are generated, which causes environmental pollution and wastes a lot of resources and energy. At the same time, the organic coating finish forms a coating film on the wall surface and exterior wall, and the pressure generated by the air and moisture is affected by the temperature and generates movement on the airtight inner and outer wall surfaces, and continuously acts on the coating film of the coating, after a period of time. , will make the wall coating film hollowing, blistering and even peel off.

Compared to these defects in organic coatings, inorganic coatings have good air permeability, anti-pollution and excellent comprehensive environmental performance. With the increasingly stringent requirements on the performance of building coatings and environmental protection, developed countries attach great importance to the research and production applications of inorganic coatings, and have done a lot of work in these areas. Our country started late in this regard, but its starting point is relatively high.

Inorganic coating is a new generation of interior and exterior wall coatings based on the latest international research field of cement-based inorganic water hardening and natural plant rubber powder. At the same time, it adopts oxidation-modified water-based mineral coatings, green environmental protection, and has a broad spectrum of antibacterial properties. The bacterial and mold inhibition rate reached 99.98% in 2 minutes.

When inorganic coatings are applied on the surface of cement mortar, concrete and masonry, they are firmly bonded to the wall through petrochemical reaction and have no obvious interface. This is fundamentally different from the previous film-forming principles of organic coatings.
