Abstract

The invention discloses a nanometer aluminium oxide-modified acrylic resin type powder coating, and relates to the technical field of production of powder coatings. The powder coating is prepared from the following raw materials in parts by mass: 90-100 parts of glycidyl methacrylate, 15-20 parts of nanometer aluminium oxide, 10-12 parts of kieselguhr, 8-10 parts of asbestos powder, 6-9 parts of carboxymethyl chitosan, 5-8 parts of dodecanedioic acid, 4-6 parts of zirconium oxide, 3-5 parts of natrolite, 3-4 parts of superfine transparent iron oxide yellow, 2-3 parts of dibutyl phthalate, 2-3 parts of polyether-modified organic siloxane and 100-120 parts of ethyl alcohol. The coating provided by the invention is nontoxic and free of solvents and volatile and toxic substances, and meets environmental requirements; the raw material utilization ratio can reach 99%; a compact coating layer is generated after spraying, and the coating layer is good in adhesive force and impact resistance, and excellent in weather resistance and corrosion resistance.

Description

Technical field: [0001] The invention relates to the technical field of powder paint production, in particular to a nano-alumina modified acrylic resin powder paint. Background technique: [0002] Powder coating is a new type of solvent-free 100% solid powder coating, which has the characteristics of no solvent, no pollution, recyclable, environmental protection, energy and resource saving, reduced labor intensity and high mechanical strength of the coating film. It is mainly divided into thermoplastic powder There are two types of coatings and thermosetting powder coatings. Thermosetting powder coating refers to the use of thermosetting resin as a film-forming substance, adding a curing agent for crosslinking reaction and heating to form an insoluble and infusible hard coating. At higher temperatures, the coating does not soften like thermoplastic coatings, but only decomposes. Since the resin used in thermosetting powder coatings is a prepolymer with a low degree of poly...
