The preparation method comprises the following steps: step 1: take calcium aluminate and mechanically ball mill it in a ball mill; step 2: take 19-28 parts of acrylate emulsion by weight , Gum Arabic 3‑8 parts, glycerin 2‑6 parts, triethanolamine 4‑7 parts, ethylene glycol butyl ether acetate 2‑6 parts, aminopropylamine dioleate 2‑5 parts, polyoxypropylene glyceryl ether 1 ‑4 parts, mixed in a mixing tank, the temperature in the mixing tank is 40‑60 °C, the stirring speed is 100‑200r / min, stirring for 30‑50min; Step 3: Add cetyl palmitic acid to the mixing tank in step 2 2-6 parts of ester, 1-4 parts of calcium aluminate, 2-5 parts of nano-calcium oxide, 2-5 parts of phthalocyanine green G, and then stirred for 20-40 minutes, cooled to form a composite nano-acrylic pigment.

Description

technical field [0001] The invention belongs to the field of pigments and relates to a composite nano acrylic pigment and a preparation method thereof. Background technique [0002] Acrylic paint is a synthetic polymer pigment, invented in the 1950s, made of pigment powder mixed with acrylic latex. Acrylic latex is also known as acrylic resin polymerized latex. There are many kinds of acrylic resins, such as methacrylic resins, and therefore, there are many kinds of acrylic paints. Foreign pigment manufacturers have produced acrylic series products, such as matt acrylic paint, semi-matt acrylic paint and glossy acrylic paint, as well as acrylic matte oil, glazing oil, molding ointment and so on. The works of acrylic paint have a longer durability, and the oil film in oil painting is easy to oxidize after a long time, and it will turn yellow and harden, which will easily cause cracks in the picture. The characteristics of acrylic paint superior to other kinds of paint are:...
