Preparation method of aluminum alloy anticorrosive material

Abstract

The invention discloses a preparation method of an aluminum alloy anticorrosive material. The preparation method specifically comprises the following steps: S1, sequentially weighing 10-15 parts of zinc oxide in parts by weight, placing the weighed zinc oxide in a zinc sulfate solution, and dropwise adding an ammonium carbonate solution under the stirring effect of a magnetic stirrer until the pHvalue of the solution reaches 7-7.5; S2, filtering the solution obtained in S1, drying the filtered upper layer substance in an oven for 10-15 h, adjusting the temperature to be 230-270 DEG C, takingthe upper layer substance out of the oven after drying is completed, and placing the upper layer substance in a fume hood for natural cooling the upper layer substance to room temperature; and S3, calcining the material obtained in S2 in a muffle furnace for 5-8 h to obtain magnetic zinc oxide. The magnetic zinc oxide particles can generate a gravitation effect with iron, cobalt and nickel simplesubstances in aluminum alloy, an adsorption effect in the early stage is realized by modified carboxyl-terminated nitrile rubber, after the anticorrosive material is solidified, the gravitation effectcan be achieved, and the stability of adhesion of the anticorrosive material and the aluminum alloy material is enhanced by 20% or above.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion materials, in particular to a method for preparing an aluminum alloy anti-corrosion material. Background technique [0002] At present, since humans began to smelt metals and use metal products, the problems of metal corrosion and protection have come along with them. Metal corrosion has caused huge losses to society. According to statistics, people smelt about 1 / 3 of the metals produced each year. 10 is damaged by corrosion, which is equivalent to about 1 / 10 of the smelters doing useless work due to the existence of corrosion every year; and the damage of metal products affected by 1 / 10 of the metal damaged by corrosion is far greater than that of metal The value of itself; and the loss of work stoppage, production stoppage and personal injury and death caused by it is incalculable, so the problem of metal corrosion and protection has attracted people's great attention. [0003] After ret...

Problems solved by technology

[0005] The purpose of the present invention is to provide a method for preparing an aluminum alloy anti-corrosion material. By adding magnetic zinc oxide particles, when applied to the surface of the aluminum alloy, the magnetic zinc oxide particles can generate an attractive force with the iron, cobalt, and nickel elements in the aluminum alloy. As a result, the modified carboxyl-terminated nitrile rubber has achieved the early adsorption effect. After the anti-corrosion material is solidified, it can produce the gravitational effect, so that the stability of the adhesion between the anti-corrosion material and the aluminum alloy material is strengthened by more than 20%. Existing aluminum alloy anti-corrosion materials are all adhered to aluminum alloy materials by glue or adhesive, which has poor stability. When used in areas with high temperature and high pressure or large temperature difference all the year round, it is easy to cause cracking of anti-corrosion materials Or fall, which leads to the problem of corrosion of the exposed aluminum alloy in the later stage
