Abstract

The invention discloses nano-powder for a photochromic coating. The nano-powder is prepared from the following components in parts by weight: 10 parts of epoxy-terminated polyether amine-coated nano-silica, 1-5 parts of epoxy-terminated polyether amine-coated purple sand and 5-10 parts of a modified sulfonated polyether amine-hyperbranched polypyrrolone copolymer, wherein the modified sulfonated polyether amine-hyperbranched polypyrrolone copolymer is obtained by enabling polyquaternium and graphene oxide to react with a sulfonated polyether amine-hyperbranched polypyrrolone copolymer. The invention also discloses the photochromic coating using the nano-powder.

Description

technical field [0001] The invention belongs to the technical field of nanometer powder, and more specifically, the invention relates to a nanometer powder used for photochromic paints and a photochromic paint obtained therefrom. Background technique [0002] Photochromic coating is a new type of functional coating, which can present good indication effect and beautification effect. Fire fighting equipment, military, camping facilities, etc. have a wide range of uses. Existing photochromic coatings have the following disadvantages: [0003] (1) The weather resistance and water resistance of the product generally cannot meet the requirements; [0004] (2) In the event of a fire, the film-forming substances of these fire-resistant coatings cannot withstand the sharply rising temperature and are quickly burned, and cannot play the role of fire prevention; [0005] (3) Poor properties such as anti-corrosion, acid and alkali resistance, and antibacterial properties. [0006] ...
