With the continuous advancement of green and low-carbon concepts and environmental protection regulations, water-based coatings are becoming more and more widely used in the fields of building decoration, wood furniture, automobile manufacturing, etc. However, water-based coatings also face some pain points, such as poor sagging, insufficient wear resistance, low coating strength, fast settlement and delamination .
The highly dispersible nanocellulose dispersion developed and produced by Nanjing Tianlu Nano Technology Co., Ltd. provides a new solution to these problems - adding a small amount of nanocellulose to aqueous coatings can significantly improve rheological performance, improve coating film strength, and extend product storage life.
Nanocellulose is a green nanomaterial derived from plant fibers. The fiber diameter is only 5-50 nanometers, the length can reach several microns, and has an extremely high aspect ratio and specific surface area. In aqueous coating systems, it can form a three-dimensional network structure, giving the coating excellent thickening, suspension and enhancement effects.
The main mechanisms of action include:
The three-dimensional network of rheology-controlled
nanocellulose can support the pigment filler when static to prevent settlement; it is quickly deconstructed during shear (stirring or construction), ensuring the fluidity of the paint and smooth construction.
Enhance the strength of the coating.
Nanocellulose forms hydrogen bonds and physical crosslinks with the resin matrix, thereby improving the tensile strength, wear resistance and adhesion of the coating.
Improve storage stability and
high dispersion nanocellulose can remain suspended for a long time, reduce coating layering and agglomeration problems, and extend shelf life.
Environmentally friendly and safe
nanocellulose is naturally non-toxic, degradable, and does not produce VOC and microplastic pollution, and meets green building and environmentally friendly coating standards.
Project: | No nanocellulose added | added 1% nanocellulose dispersion |
---|---|---|
Leveling | Medium, easy to slim | Excellent, smooth construction |
Pigment settlement | Apparent settlement stratification | Basically no settlement |
Coating hardness | HB | 2H |
Wear resistance | ordinary | Increased by more than 30% |
Storage stability | Easy to stratify in 3 months | Stable suspension for 12 months |
The above data comes from the laboratory test of Nanjing Tianlu Nano Technology Co., Ltd., and the actual effect varies according to the formula.
