Abstract

The invention discloses a novel epoxy aluminum alloy fireproof decorative coating, and relates to the technical field of coatings. The coating is prepared from the following raw materials in parts byweight: 30-60 parts of epoxy resin, 10-25 parts of acrylic resin, 10-15 parts of talcum powder, 20-40 parts of bentonite, 17-23 parts of asbestos powder, 13-15 parts of expanded graphite, 26-33 partsof pigment filler, 1-5 parts of a defoaming agent and 18-22 parts of an auxiliary agent, wherein the auxiliary agent is one or two of ceramic zinc borate or aluminum hydroxide. By adding ceramic zincborate and / or aluminum hydroxide into the formula of the coating, the coating is endowed with excellent flame retardancy and higher strength, and the expanded graphite can expand in case of a fire, sothat a heat source is isolated, and the purpose of fire prevention is achieved; and meanwhile, the prepared fireproof coating is safe, environmentally friendly, high in strength, good in adhesive force, simple in preparation method and suitable for industrial use.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a novel epoxy aluminum alloy fireproof decorative coating. Background technique [0002] Epoxy aluminum alloy is generally obtained by using TRI to treat the surface of the aluminum alloy. A layer of metal oxide film is formed after the surface of the aluminum alloy is soaked in a liquid medicine. The joint surface has good sealing performance and excellent waterproof performance. [0003] At present, fire retardant coatings are more and more widely used in petrochemical, electric power, industrial and civil construction, machinery and other industries. Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. [0004] Therefore, coating the surface of epoxy aluminum alloy with fireproof...
