Hyperbranched polymer delustering agent as well as preparation method and application thereof

The invention discloses a hyperbranched polymer delustering agent and a preparation method and application thereof.The preparation method comprises the steps that natural clay of a lamellar structure serves as a raw material and is evenly mixed with a hyperbranched polymer with carboxyl at the end group, heating is conducted, so that hydroxyl on a stripped clay lamellar layer and carboxyl of the hyperbranched polymer completely form hydrogen bonds or are subjected to an esterification reaction, and the hyperbranched polymer delustering agent is obtained; the clay composite hyperbranched polymer microspheres are constructed by utilizing the three-dimensional characteristics of the hyperbranched polymer, and the matting agent with a flame-retardant effect is obtained by combining the flame retardance of the clay. In addition, nano antibacterial particles can be added to construct microspheres carrying the antibacterial particles, so that the delustering agent has a good antibacterial effect, and the problem of
