Embodiment 1

[0019] A preparation method of a water-free degreasing antirust agent, comprising the following components in terms of weight percentage: nonionic surfactant containing alkyl alcohol, 1%; ethanolamine, 1%; sodium citrate, 0.1%; Demulsifier, 0.1%; urotropine, 0.1%; deionized water, the balance;

[0020] The specific preparation method is as follows: uniformly mix the non-ionic surfactant containing alkyl alcohol, ethanolamine, sodium citrate, demulsifier, urotropine and deionized water according to the proportioning ratio to obtain the water-free degreasing antirust agent.

[0021] The degreasing antirust agent can be applied to the surface of the material to be treated by soaking, spraying, or smearing. After the coating is completed, the material to be treated should be dried or dried naturally;

[0022] Wherein, the natural drying is air drying at normal temperature, and the drying temperature is 60°C.

Embodiment 2

[0024] A preparation method of a water-free degreasing antirust agent, comprising the following components in terms of weight percentage: nonionic surfactant containing alkyl alcohol, 30%; ethanolamine, 30%; sodium citrate, 10%; Demulsifier, 8%; urotropine, 10%; deionized water, the balance;

[0025] The specific preparation method is as follows: uniformly mix the non-ionic surfactant containing alkyl alcohol, ethanolamine, sodium citrate, demulsifier, urotropine and deionized water according to the proportioning ratio to obtain the water-free degreasing antirust agent.

[0026] The degreasing antirust agent can be applied to the surface of the material to be treated by soaking, spraying, or smearing. After the coating is completed, the material to be treated should be dried or dried naturally;

[0027] Wherein, the natural drying is air drying at normal temperature, and the drying temperature is 60°C.

Embodiment 3

[0029] A preparation method of a water-free degreasing antirust agent, comprising the following components in terms of weight percentage: nonionic surfactant containing alkyl alcohol, 5%; ethanolamine, 5%; sodium citrate, 0.1%; Demulsifier, 5%; urotropine, 5%; deionized water, the balance;

[0030] The specific preparation method is as follows: uniformly mix the non-ionic surfactant containing alkyl alcohol, ethanolamine, sodium citrate, demulsifier, urotropine and deionized water according to the proportioning ratio to obtain the water-free degreasing antirust agent.

[0031] The degreasing antirust agent can be applied to the surface of the material to be treated by soaking, spraying, or smearing. After the coating is completed, the material to be treated should be dried or dried naturally;

[0032] Wherein, the natural drying is air drying at normal temperature, and the drying temperature is 60°C.

Abstract

The invention discloses a preparation method and an application method of a washing-free degreased antirust agent, and belongs to the technical field of antirust. The washing-free degreased antirust agent is prepared by evenly mixing nonionic surface active agent containing alkyl alcohol, ethanolamine, sodium citrate, a demulsifier, urotropine and deionized water according to proportions. The degreased antirust agent can be used in a spray occasion particularly sensitive to foam, sprayed, and impregnated. A layer of clear impenetrable dry film is formed on the surface of metal, and the degreased antirust agent can be directly sprayed without washing and has no influence on the binding force of coating. The degreased antirust agent is compatible with a silane film and can be used with silane in a matched mode, the naked film is high in corrosion resistance, and the indoor rust resistance can last for 10-30 days. The degreased antirust agent is environmentally friendly, does not contain phosphorus, alkali and nitrite, and is simple in wastewater treatment and low in cost.

Description

technical field [0001] The invention relates to a degreasing antirust agent, in particular to the preparation and use method of a water-free degreasing antirust agent, belonging to the technical field of antirust. Background technique [0002] In the process of production and processing, the surface of the workpiece will inevitably be polluted, and in the coating process, the workpiece that needs to be sprayed should be kept clean and free from rust, so it needs to be cleaned with a corresponding cleaning agent to ensure or Improve product quality. The purpose of cleaning is generally to remove grease, organic residues, pigment dirt, covering layers and oxidized substances; in addition, the metal parts produced need to be rust-proofed. The existing degreasing agents can generally achieve degreasing effect but need to be washed with water, while those that can achieve the effect of no-washing and anti-rust can not achieve the degreasing effect, and it is difficult to achieve...
