Description
Technical field
The present invention relates to a kind of replacement aluminium alloy light pole anodic oxidation formula and techniques, belong to metal material surface engineering
Field.
Background technology
Aluminium alloy light pole specific strength is high, is readily transported, and the service life is long compared with irony light pole, and can 100% recycling, while can
Different shapes is made by spinning process, meets aesthetic, has generally been used in the country such as America and Europe at present.But aluminium closes
The corrosion resistance of gold is poor, is required to improve its protective and decoration by anode oxidation process generally for aluminium alloy light pole
The functions such as property.But use anodic oxidation to aluminium alloy light pole carry out processing there are some drawbacks, such as part electric energy to convert
For heat so that the operating temperature of electrolyte increases, causes the porosity of the oxidation film obtained to increase, reduce corrosion resistance；It is big simultaneously
The electric energy consumed when batch production is more, and electrolyte is unfavorable for recycling, and increases the cost of product.
Invention content
The purpose of the present invention is to provide a kind of for the chemical surface treatment technique of aluminium alloy light pole to substitute anode
Oxidation, in the case that cold so that one layer of fine and close oxidation film of aluminium alloy light pole Surface Creation, its is resistance to reach raising
The purpose of corrosion.
The present invention provides a kind of method substituting aluminium alloy light pole anodic oxidation, this method includes：
Step 1：To being washed twice after aluminium alloy light pole spray industrial cleaning agent carries out oil removing, weak base washes processing；
Step 2：By following recipe configuration treatment fluid, in formula, per 1000ml solution in contain following component：
| Ingredient | Content |
| Hydrogen peroxide | 200ml |
| Oxalic acid | 50-80g |
| Citric acid | 40-50g |
| Lactic acid | 10-20g |
| Surfactant E1310 | 1-10g |
| Imidazoline inhibitor | 1-5g |
| Polyethylene glycol PEG600 | 20-40g |
| Water | It is remaining |
Step 3：The processed aluminium alloy light pole of step 1 is placed in being formulated described in step 2, keeps 10-25 DEG C for the treatment of temperature,
Processing time 3-10 min；
Step 4：By step 3 treated aluminium alloy light pole drying and processing.
Compared with the prior art, the advantages of the present invention are as follows：One side processing procedure need not be powered, and save the energy, together
Shi Chengben is only the 30%-40% of anodic oxidation；On the other hand the surface porosity factor obtained by this technique is low, does not need later stage envelope
Processing is closed, improves efficiency, while the treatment fluid is free of any heavy metal ion, can recycle completely, safety and environmental protection.
Specific implementation mode
【Embodiment 1】677 parts of pure water will be measured first, and 40 parts of citric acids and 50 parts of oxalic acid are added in water and are stirred
It mixes, 1 part of imidazoline inhibitor and 10 parts of lactic acid is added thereto and continues to stir later, by 200 parts of hydrogen peroxide（30wt%）It is added
In continue to stir, further add 20 parts of polyethylene glycol PEG600, be eventually adding 2 parts of surfactant E1310.
It is washed twice after carrying out oil removing pretreatment to light pole in industrial cleaning agent, then by processed street lamp
Bar is put into the treatment fluid configured according to the above ratio, 25 DEG C, processing time 10min for the treatment of temperature is kept, by the road after processing
Lamp stand is dried at 85 DEG C can
【Case study on implementation 2】Formula is shown in Table 1, and preparation process is identical.
【Case study on implementation 3】Formula is shown in Table 1, and preparation process is identical.
