A durable sign coating is prepared from raw materials in parts by weight as follows: 6-9 parts of alkyd resin, 3-6 parts of graphene, 5-8 parts of ethyl acetate, 2-4 parts of aluminum oxide, 4-7 parts of amino resin, 8-11 parts of sepiolite powder, 5-7 parts of methallyl alcohol, 3-5 parts of ethylene glycol, 1-3 parts of a plasticizer, 2-4 parts of copper alloy powder, 4.5-8 parts of alcohol-soluble resin, 3-7 parts of stearic acid, 2-5 parts of calcium carbonate, 1-5 parts of bougainvillea speetabilis sawdust, 6-14 parts of chlorinated paraffin, 1-2 parts of barium sulfate and 2-5 parts of phosphor. The coating has the benefits as follows: the sign coating has a certain fluorescence effect, is particularly good in night effect and can resist acid, base and sunshine corrosion. |
