A silicone-acrylic binder is made from a combination of I) a first aqueous emulsion containing a soft acrylic polymer, II) a second aqueous emulsion containing a silicone resin. The silicone-acrylic binder can be used to prepare a thermal insulation coating composition that may be applied on a metal (e.g., steel) substrate or primed substrate. A thermal insulation coating prepared by drying the thermal insulation coating composition provides the metal or primed substrate with resistance to corrosion under insulation.

The present disclosure belongs to the technical field of coatings, and in particular relates to a graphene-modified silicon-titanium nano-polymer slurry, and a preparation method and use thereof. When the graphene-modified silicon-titanium nano-polymer slurry provided by the present disclosure is added to a polymer coating, the high resistance of graphene to gas and liquid permeation and the silicon-titanium graphene network structure can significantly increase the resistance of a formed coating layer to medium permeation; due to the corrosion resistance of graphene, titanium, and silicon nanoparticles, a formed coating layer has very high stability, is not easy to react with various media such as an acid, an alkali, and a salt, is not easily consumed to form pores, and is not easy to react with corrosive media to generate soluble salts or cathodic loose and expanded products, which ensures the long-term stability of a composition and a structure of the coating layer.
