Application of high surface carbon black dispersant in coatings
High surface carbon black dispersant significantly improves coating performance by reducing the interaction
between carbon black particles. The specific application effects are as follows:
I. Core mechanism
Dispersion
Through the chemical bonding between the anchoring group and the active site on the carbon black surface,
the carbon black particles are evenly dispersed in the coating system to avoid agglomeration and sedimentation
in combination with the steric hindrance effect.
Stabilization
Form a protective film on the surface of carbon black particles to prevent particles from reaggregating, extend the
storage life of the coating, and reduce problems such as flocculation and stratification sedimentation.
Viscosity reduction
Through the steric hindrance effect of high molecular weight dispersants, the viscosity of the coating system is
reduced, the construction fluidity is improved, and the production efficiency is improved.
II. Optimization of coating performance
Improve gloss and flatness
Enhance the uniformity of the dispersion of carbon black particles, form a smoother microstructure on the coating
surface, improve gloss and anti-yellowing properties, and extend the service life of the coating film.
Enhance hiding power and durability
Evenly dispersed carbon black particles can effectively absorb light and improve hiding effect. At the same time,
by reducing ultraviolet penetration, the weather resistance and aging resistance of the coating film can be enhanced.
Improve construction performance
Reducing viscosity can reduce splashing and sagging during construction, improve the adhesion of the coating to the
substrate, and ensure uniform coating.
III. Application advantages and value
Improve product quality
By solving the problem of carbon black being difficult to disperse, avoiding defects such as color difference and floating
color, the quality stability of the coating can be significantly improved.
Reducing production costs
Optimizing the dispersion process can shorten the grinding time, reduce the amount of dispersant, improve production
efficiency, and reduce energy consumption and raw material costs.
Enhance market competitiveness
Meet the stringent requirements of high-end coatings for gloss, hiding power and durability, increase product added
value, and expand application areas.
IV. Application scenarios
Architectural coatings: Enhance the weather resistance and decorativeness of exterior wall coatings.
Automotive coatings: Improve the gloss and scratch resistance of car paints.
Industrial coatings: Improve the hiding power and chemical resistance of anti-corrosion coatings.
Plastic coatings: Enhance the conductivity and wear resistance of plastic products.
V. Technology development trends
Environmentally friendly dispersants: Develop water-based and solvent-free dispersants to reduce VOC emissions.
Multifunctional dispersants: Integrate multiple functions such as dispersion, stabilization, and flow to simplify formula
design.
Intelligent dispersion technology: Combine nanotechnology and AI algorithms to achieve precise control of the dispersion
process.
High surface carbon black dispersants significantly improve the gloss, hiding power, durability and construction performance
of coatings by optimizing carbon black dispersibility. They are indispensable key additives in the modern coatings industry.
With technological advances, their application scope will continue to expand, driving the coatings industry towards high
performance and environmental protection.
