An inorganic nanomaterial for continuous formaldehyde removal includes the following components in part by mass: 20-30 parts of water, 0.1-0.3 parts of cellulose, 0.1-0.2 parts of a defoamer, 0.3-0.6 parts of a dispersant, 0.3-0.6 parts of a wetting agent, 20-25 parts of titanium dioxide, 5-10 parts of kaolin, 10-15 parts of heavy calcium, 30-40 parts of modified inorganic hybrid resin, 0.1-1 part of a film-forming additive, and 0.1-1 part of propylene glycol. After inorganic hybrid modification, an ammonia group is introduced, which can continuously and effectively decompose formaldehyde in the environment. A coating film not only has good anti-mildew, anti-algae, fire prevention, and heat insulation functions, but also has a continuous formaldehyde removal function. The formaldehyde removal efficiency is greater than 95%. The durability of formaldehyde purification effect is 90%.

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.

The present invention provides an amide acid oligomer which has specific composition and which is capable of providing a cured product having excellent physical properties, in particular, an excellent glass transition temperature, etc.

A coating composition contains silica fine particles having an average particle size of 3 nm or more and 25 nm or less, a solvent having a boiling point of 150° C. or higher and 300° C. or lower, and water. The content of the silica fine particles is 0.1 mass% or more and 5 mass% or less. The content of the solvent is 20 mass% or more and 70 mass% or less.
