The invention discloses an anticorrosion stable anti-aging plastic plate. The anticorrosion stable anti-aging plastic plate is prepared from the following raw materials in parts by weight: 0.7-1 part of calcium stearate, 2-3 parts of octyl isothiazolinone, 2-3 parts of sucrose acetate isobutyrate, 0.7-1 part of glycereth-n cocoate, 1-2 parts of trithiocyanuric acid, 110-160 parts of polyvinyl chloride, 1-2 parts of triphenylphosphine, 10-13 parts of polyisoprene, 27-30 parts of dimethyl nylon acid, 0.5-1 part of fulvic acid, 0.1-0.2 part of zinc pyrithione, 4-6 parts of dimethyl fumarate, 10-14 parts of sea-foam stone powder, 0.5-1 part of potassium citrate, 0.6-1 part of diisopropyl ethanol amine, 3-4 parts of rosin alcohol, 0.1-0.5 part of aluminum potassium sulfate and 0.1-0.3 part of a silane coupling agent KH560. The anticorrosion stable anti-aging plastic plate disclosed by the invention has the advantages that anticorrosion capability of the plate finished product can be effectively improved as octyl isothiazolinone, dimethyl fumarate and the like are added, the added triphenylphosphine and the like can improve antibacterial property, the added zinc pyrithione, calcium stearate and the like can improve stability of the plate finished product, the raw materials are reasonably treated, and the anticorrosion stable anti-aging plastic plate has high anticorrosion capability and antibacterial property and superior overall performance.
