Application Analysis of Ceramic Micropowder instead of Titanium Dioxide in Waterborne Coatings

In response to the development needs of the times, new materials continue to emerge in the development of the coating industry, and are rationally used by innovative manufacturers, in order to continuously innovate their own products and open up the market. And possess a dominant role, and bring huge business opportunities and profit space for it, which puts forward higher requirements for the research and development of new materials.
In order to meet the needs of the development of the times, Huijing has developed a new type of functional material that can replace titanium dioxide—ceramic powder and active ceramic powder; it can not only improve the product’s high temperature resistance, corrosion resistance, wear resistance, Weather resistance can reduce production costs to a certain extent. Now the mature applications are: coating, engineering plastic modification, special rubber, papermaking and other fields. The following is a brief description of the application of ultrafine ceramic powder in coatings:
The main components of composite ceramic powder are SiO2 and Al203, with good dispersibility, high hiding power, whiteness up to 94 or more, low density, good light scattering, and refractoriness up to 1300 degrees or more. The material composition of aluminum silicate makes it have good acid and alkali resistance, corrosion resistance and insulation properties, and has a good reflection and heat insulation function. Therefore, active ceramic powder is widely used in architectural coatings and industrial maintenance coatings and reflections.Insulation coating.
The characteristics of ceramic powder make it have the characteristics of titanium dioxide. It can partially replace the amount of titanium dioxide and reduce the production cost to a certain extent. The ultrafine ceramic powder of 6000 mesh can replace the amount of titanium dioxide in a large amount, which can reduce the cost while eliminating The photo-flocculation phenomenon caused by the use of titanium dioxide prevents yellowing of paint, especially water-based paint. Suggested use ratio: 10-30%, can be used together with other ordinary fillers, with good compatibility and obvious effect. The thixotropy of ultra-fine materials makes it have good UV shielding performance, and it is very effective for reflective heat insulation coatings! .
Experiments and applications show that as a new functional filler material, ceramic powder plays a very good role in improving the overall cost performance of the coating: it improves the coating’s anti-corrosion, high temperature resistance, weather resistance, insulation, reflective heat insulation and surface properties. Scratch resistance, scrubbing resistance, and greatly reduce the production cost of enterprises; ceramic micropowder is a new type of functional environmentally friendly filling material that is worthy of attention.
