Abstract

The invention discloses a zirconia-doped rare earth-modified acrylic resin type powder coating, and relates to the technical field of powder coating production. The powder coating is prepared from the following raw materials in parts by mass: 90-100 parts of glycidyl methacrylate, 15-20 parts of zirconia, 5-8 parts of rare earth, 10-12 parts of diatomite, 8-10 parts of asbestos powder, 5-8 parts of dodecanedioic acid, 4-6 parts of white carbon black, 3-5 parts of natrolite, 3-4 parts of ultra-fine transparent yellow iron oxide, 2-3 parts of dibutyl phthalate, 2-3 parts of polyester-modified organosiloxane, 1-2 parts of sodium metaborate and 100-120 parts of ethanol. The coating provided by the invention is non-toxic and free of solvents and volatile toxic substances, and complies with environmental requirements; the raw material utilization rate reaches 99%; a dense coating is formed after spraying, and high adhesion, good impact resistance, and excellent weather resistance and corrosion resistance are realized.

Description

Technical field: [0001] The invention relates to the technical field of powder coating production, in particular to a zirconia-doped rare earth modified acrylic resin type powder coating. 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 wit...
