Embodiment 1

[0039] The rust-removing and antirust agent of the present embodiment comprises the components of the following parts by weight: 38 parts of PSHAD, 4 parts of stearic acid, 5 parts of oleic acid, 5 parts of nano zinc oxide, 4 parts of aluminum metaphosphate, 2 parts of vinyl acetate , 4 parts of potassium pyrophosphate, 6 parts of triethanolamine, 4 parts of diethanolamine, 6 parts of laurate, 4 parts of ethyl methacrylate, 4 parts of butyl methacrylate, 6 parts of dimethyl siloxane, 8 parts of water share.

[0040] Its preparation method comprises the following steps:

[0041] (1) Mix PSHAD, stearic acid, oleic acid, nano-zinc oxide, aluminum metaphosphate, potassium pyrophosphate, and water evenly, and place it under ultrasonic conditions for 10 minutes to obtain mixture A;

[0042] (2) At a temperature of 25°C-45°C, triethanolamine, diethanolamine, laurate, ethyl methacrylate, and butyl methacrylate are sequentially added to vinyl acetate and stirred evenly to obtain a mixtu...

Embodiment 2

[0046] Compared with Example 1, the difference is only: the composition and content of the rust remover and antirust agent are different, and the rust remover and antirust agent of the present embodiment includes the following components by weight: 32 parts of PSHAD, 5 parts of stearic acid, oil 6 parts of acid, 6 parts of nano zinc oxide, 5 parts of aluminum metaphosphate, 2 parts of vinyl acetate, 4 parts of potassium pyrophosphate, 6 parts of triethanolamine, 5 parts of diethanolamine, 6 parts of laurate, 5 parts of ethyl methacrylate 4 parts, 4 parts of butyl methacrylate, 6 parts of dimethyl siloxane, 8 parts of water.

Embodiment 3

[0048] Compared with Example 1, the difference is only: the composition and content of the rust remover and antirust agent are different, and the rust remover and antirust agent of the present embodiment includes the following components by weight: 40 parts of PSHAD, 4 parts of stearic acid, oil 5 parts of acid, 5 parts of nano zinc oxide, 4 parts of aluminum metaphosphate, 2 parts of vinyl acetate, 4 parts of potassium pyrophosphate, 5 parts of triethanolamine, 4 parts of diethanolamine, 5 parts of laurate, 4 parts of ethyl methacrylate 4 parts, 4 parts of butyl methacrylate, 6 parts of dimethyl siloxane, 8 parts of water.

Abstract

The invention relates to a rust removal and prevention agent as well as a synthesis process and application thereof. The rust removal and prevention agent is prepared from PSHAD, stearic acid, oleic acid, nano-zinc oxide, aluminum metaphosphate, vinyl acetate, potassium pyrophosphate, triethanolamine, diethanol amine, laurate, ethyl methacrylate, butyl methacrylate, a coupling agent and water, wherein the ratio of m1 to m2 to m3 is (47-53): (18-22): (15-17). M1 is the total mass of PSHAD, nano zinc oxide, aluminum metaphosphate and potassium pyrophosphate, m2 is the total mass of stearic acid, oleic acid, triethanolamine and diethanol amine, and m3 is the total mass of vinyl acetate, laurate, ethyl methacrylate and butyl methacrylate; pSHAD is a mixture of phosphoric acid and aluminum zinc phosphate. The rust removing and preventing agent can effectively remove rust on the metal surface at the same time, enables the rusted metal surface to be bright and flat, and can generate a compact protective film on the metal surface to prevent the metal surface from making contact with the outside.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to a rust remover and antirust agent and its synthesis process and application. Background technique [0002] It is estimated that the annual corrosion rate of steel products and metal equipment in the world is as high as 9.85%, which is equivalent to the economic loss of about 850 billion U.S. dollars due to steel corrosion problems caused by improper protection or lack of protection every year, accounting for about 10% of the total national economic production. Not only that, the equipment will be damaged due to corrosion, which will cause the factory to stop production, reduce product quality, and even cause serious casualties or huge environmental pollution. Rust has become the biggest enemy of steel. Therefore, how to protect steel, prevent it from rusting and deterioration, and increase its service life has become a problem of general concern in the current soc...
