Problems solved by technology

[0002] There are problems of oxidation and rust on the metal surface. When the rust reaches a certain level, the problem of perforation and water leakage may occur. The current rust removal methods mainly include physical and artificial rust removal and chemical rust removal. Rust has high efficiency and simple process operation, but the current chemical derusting method uses a large amount of hydrochloric acid, which will generate acid mist, and the generated small molecule hydrogen is easy to enter the metal lattice, resulting in the problem of "hydrogen embrittlement"

Embodiment 1

[0027] The Krustling material provided in this example includes the following components by weight: 42 parts of special copolymer silicone acrylic emulsion, 16 parts of composite organic acid, 0.2 parts of defoamer, 2 parts of triethanolamine, 2 parts of polyacrylamide, surface 5 parts of activator, 4 parts of complexing agent, 0.3 part of anti-flash rust agent, 0.1 part of preservative, 0.1 part of solubilizer, water surplus; Wherein, the weight ratio of oxalic acid and phthalic acid in the composite organic acid is 1: 0.8;

[0028] The preparation method of the said cloxaline comprises the following steps: taking the special copolymer silicone acrylic emulsion and compound organic acid and adding it into water, stirring for 30 minutes at a rotating speed of 300-350r / min, and then adding defoamer, triethanolamine, polyacrylamide , surfactant and complexing agent, and then stirred at a speed of 500-600r / min for 20 minutes, and finally added anti-flash rust agent, preservative ...

Embodiment 2

[0030] The only difference between the clarazole material provided in this example and Example 1 is that the special copolymer silicone acrylic emulsion is 38 parts, and the composite organic acid is 17 parts.

Embodiment 3

[0032] The only difference between the clarazole material provided in this example and Example 1 is that the special copolymer silicone acrylic emulsion is 45 parts, and the composite organic acid is 12 parts.

Abstract

The invention discloses a rust power material as well as a preparation method and application thereof, which belongs to the technical field of materials. The rust power material provided by the invention is prepared from the following components in parts by weight: 35 to 50 parts of silicone acrylic emulsion, 10 to 20 parts of composite organic acid, 0.1 to 0.3 part of a de-foaming agent, 1 to 3 parts of triethanolamine, 1 to 3 parts of polyacrylamide, 2 to 8 parts of a surfactant and 3 to 5 parts of a complexing agent. The composite organic acid is oxalic acid and phthalic acid. According to the technical scheme provided by the invention, acid mist cannot be generated in the rust removal process, and the rust power material has very good seepage force and polymerization fastening force, so that the rust removal speed is high, and meanwhile, it can be guaranteed that the rust-removed metal surface is transparent and bright.

Description

technical field [0001] The invention belongs to the technical field of material synthesis, and in particular relates to a clarazole material and its preparation method and application. Background technique [0002] There are problems of oxidation and rust on the metal surface. When the rust reaches a certain level, the problem of perforation and water leakage may occur. The current rust removal methods mainly include physical and artificial rust removal and chemical rust removal. Rust has high efficiency and simple process operation, but the current chemical derusting method uses a large amount of hydrochloric acid, which will generate acid mist, and the generated small molecule hydrogen is easy to enter the metal lattice, resulting in the problem of "hydrogen embrittlement". Contents of the invention [0003] The object of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a high-efficiency clarazole material that does not g...
