Problems solved by technology

This traditional method not only has cumbersome procedures and occupies a large area, but also consumes too much cleaning water and chemicals
In order to solve the above problems and achieve the purpose of simplifying the process and shortening the pretreatment time, it is possible to add appropriate surfactants and other agents to the pickling solution to achieve degreasing and deoxidizing in one step. However, the existing degreasing products , some have disadvantages such as poor corrosion inhibition effect and low oil yield

specific Embodiment 1

[0009] Take 3 parts of sodium lauryl sulfate and 0.1 part of sodium dihexyl succinate sulfonate, add 1000 parts of water and stir to dissolve, then add 25 parts of concentrated sulfuric acid, stir and dissolve to obtain the product. When in use, put the aluminum alloy into the product at room temperature and soak for 1-5 minutes to complete the degreasing process.

specific Embodiment 2

[0010] Take 5 parts of sodium lauryl sulfate, 1 part of sodium dihexyl succinate sulfonate, add 1000 parts of water and stir to dissolve, then add 35 parts of concentrated sulfuric acid, stir and dissolve to obtain the product. When in use, put the aluminum alloy into the product at room temperature and soak for 1-5 minutes to complete the degreasing process.

specific Embodiment 3

[0011] Take 4 parts of sodium lauryl sulfate and 2 parts of sodium dihexyl succinate sulfonate, add 1000 parts of water and stir to dissolve, then add 30 parts of concentrated sulfuric acid, stir and dissolve to obtain the product. When in use, put the aluminum alloy into the product at room temperature and soak for 1-5 minutes to complete the degreasing process.

Abstract

The invention discloses an aluminium alloy surface acid degreasing agent which is characterized by comprising the following components in part by weight: 25 to 35 parts of concentrated sulphuric acid, 3 to 5 parts of sodium dodecyl sulfate, 0.1 to 2 parts of diethyl succinate sodium sulfonate and 1,000 parts of water. The aluminium alloy surface acid degreasing agent can be used for an acid pretreatment tank of products such as an aluminium section, an aluminium alloy and the like, has strong effects of removing oil stain and removing oxide, has slight corrosion to an aluminium base and has good gloss. The aluminium alloy surface acid degreasing agent can be operated at normal temperature, energy is saved and the acid mist overflowing and the acid pickle discharge are reduced, so that the damage to human bodies and the pollution to the environment are reduced in the production link.

Description

technical field [0001] The invention relates to an acid degreaser for the surface of an aluminum alloy, which belongs to the technical field of metal surface cleaning treatment. Background technique [0002] Aluminum alloy or aluminum profile electroplating, degreasing and deoxidizing before coating are the key processes to ensure the quality of coatings and coatings. The traditional degreasing and deoxidizing is to carry out alkaline degreasing first, and then carry out acidic deoxidizing after washing. Degreasing and deoxidizing are carried out step by step. This traditional method not only has cumbersome procedures and takes up a lot of land, but also consumes too much cleaning water and chemicals. In order to solve the above problems and achieve the purpose of simplifying the process and shortening the pretreatment time, it is possible to add appropriate surfactants and other agents to the pickling solution to achieve degreasing and deoxidizing in one step. However, the...
