Embodiment 1

[0037] Each component quality is in the embodiment one:

[0038]

[0039]

[0040] The preparation method is:

[0041] (1) Put epoxy resin E-44 into a container, put it into a water bath and raise the temperature to about 50°C.

[0042] (2) Take out the container and add xylene and use a glass rod for preliminary stirring. After stirring evenly, add absolute ethanol, also use a glass rod for preliminary stirring, and cool to room temperature.

[0043] (3) Weigh aluminum tripolyphosphate and put it into the container after grinding, and use a glass rod for preliminary stirring until the stirring is uniform.

[0044] (4) Weigh the zinc phosphate and grind it into the container, and use a glass rod for preliminary stirring until it is evenly stirred.

[0045] (5) Add iron oxide red to the container after weighing and grinding, and stir evenly with a glass rod.

[0046] (6) Weigh the zinc molybdate and add it into the container, and stir evenly with a glass rod.

Embodiment 3

[0055]

[0056]

[0057] See Example 1 for the preparation methods of Example 3 and Example 2, and will not repeat them here. The performance parameters of the final prepared coating are: the hardness of the paint film is expressed as 3H in pencil hardness, the adhesion level is 0, and the impact strength According to the GB / T1732-1993 standard test, the drop height of the weight is 50CM, and the paint film has no cracks, wrinkles and peeling off. The salt water resistance test is soaked in 5% NaCl solution for 48 hours at room temperature without foaming.

Abstract

The invention discloses stable permeation composite type rust coating and a preparation method thereof. The stable permeation composite type rust coating is formed by mixing epoxy resin E-44, xylene, absolute ethyl alcohol, aluminum triphosphate, zinc phosphate, iron oxide red, zinc molybdate, penetrant epoxy phosphate, a dispersing agent, a defoaming agent and a curing agent. Antirust agents are aluminum triphosphate, zinc phosphate and zinc molybdate. Triphosphate radical ions can have a stronger chelating ability with various metal ions, and a passive film is formed on the surface of a coated object; zinc phosphate and ferric ions have a higher condensation ability, phosphate anions react with iron anodes, a firm protection film with ion phosphate as a main body can be formed, and the compact purification film is insoluble in water, high in hardness and excellent in adhesive force; zinc molybdate can release molybdic acid ions, a composite insoluble substance formed on the surface of steel has an anti-rust effect; in this way, the anti-corrosion performance of the coating is excellent through the synergistic effect of the components.

Description

technical field [0001] The invention relates to an anticorrosion coating for metal, in particular to a novel coating suitable for rusty metal substrates. Background technique [0002] Affected by the rapid development of the modern metal industry, various metal industries have begun to focus on the anti-corrosion and protection of metal materials. According to statistics, one-fifth of the world's total annual metal output is damaged due to metal corrosion and rust, and the economic loss caused by corrosion is about 6.5 trillion yuan. Every year, one twenty-fifth of my country's gross national product is lost due to the corrosion of metal materials, which has far exceeded the sum of losses caused by natural disasters. [0003] The traditional anti-corrosion coating must first carry out strict treatment on the metal surface to remove rust. However, due to the influence of construction conditions, etc., it is difficult to obtain an ideal metal surface, and the cost is high. ...
