Embodiment Construction
[0014] A strip-shaped metal aluminum pigment with enhanced anti-oxidation, made of the following raw materials in parts by weight (kg): 70 flake aluminum powder, 14 methacryloxypropyl trimethoxysilane, an appropriate amount of absolute ethanol, three Methylol propane triacrylate 28, acrylic acid 1, azobisisobutyronitrile 0.09, polyvinylpyrrolidone 1.75, N, N ethylene bisricinoleic acid amide 2.5, polypropylene 17, antioxidant 10101.5, thio Diethylene glycol 3, lauric acid 2, p-toluenesulfonic acid 0.05.
[0015] The strip-shaped metallic aluminum pigment of described a kind of anti-oxidation enhancement is made by the following specific steps:
[0016] (1) Dissolve methacryloxypropyltrimethoxysilane in 4 times the amount of absolute ethanol, then add flake aluminum powder, heat to 55°C, react for 1 hour and wash with absolute ethanol several times, vacuum drying to obtain coupling modified aluminum powder;
[0017] (2) Add 2 times the amount of absolute ethanol to the coupli...
