AI Technical Summary
In existing flame-retardant ink systems, benzidine yellow pigment has poor compatibility with resin substrates and uneven dispersion of flame-retardant components, which makes the coating easy to burn at high temperatures and release toxic fumes, making it difficult to meet safety standards for high-end scenarios.
Hyperbranched flame-retardant polymers are combined with benzidine yellow pigments. Through a multi-step reaction, hyperbranched flame-retardant polymers with fluorine-containing long-chain units as the backbone are constructed, which encapsulate the benzidine yellow pigments to form a uniform nanoscale composite. The flame-retardant components and pigments form a dense protective layer at high temperatures, which hinders heat transfer.
It improves the flame retardancy and dispersibility of pigments, maintains the high tinting strength of pigments, significantly enhances the dispersibility and compatibility of pigments in substrates, extends the service life of pigments, and inhibits oxidative fading at high temperatures.
