Abstract
The invention relates to the technical field of refrigerating process, in particular to an online oxidization process for extruded aluminum pipes. The online oxidization process includes cooling the extruded aluminum pipes with water until temperature of the extruded aluminum pipes is equal to the room temperature, draining, soaking the extruded aluminum pipes in treatment liquid for 8-15 seconds, drying the extruded aluminum pipes at the temperature of 80-120 DEG C for 4-10 seconds. The treatment liquid comprises, by weight, 350-450g of polyurethane, 350-400g of acrylic resin, 150-250g of diluents and 50-100g of curing agents. In the online oxidization process, on the basis of a high-polymer material film formation mechanism, essential components of high-polymer materials and other diluents are screened and compounded, and an antiseptic treatment liquid product utilizing the high-polymer material as the essential film formation substance and containing no harmful substances such as aromatics is studied out. The extruded aluminum pipes are subjected oxidization treatment, and accordingly have high salt spray resistance and heat and humidity resistance, have antiseptic capacity much higher than that of other types of primers, and also have high seepage force so that corrosion resistance of the surfaces of the aluminum pipes is improved greatly.

Further, described treatment solution is comprised of the raw material of following weight proportion:
Preferably, the raw material by following weight proportion forms:
Preferably, described thinner is lacquer thinner.
Further, the preparation method of described treatment solution is characterized in that, step is as follows:
1., the part thinner is added in the urethane, be dispersing and mixing in the high speed dispersor of 1500～1800rpm at rotating speed;
2., will remain thinner and be added in the acrylic resin, be dispersing and mixing in the high speed dispersor of 1500～1800rpm at rotating speed;
3., mix 1. and 2., add simultaneously solidifying agent, be dispersing and mixing in the high speed dispersor of 1500～1800rpm at rotating speed, and get final product.
Extruded aluminum tube on-line oxidation technique of the present invention, on the basis of macromolecular material membrane formation mechanism, by the major ingredient such as macromolecular material and other thinner screening and composite, work out the treatment solution product take macromolecular material as main film forming substance, the objectionable impuritiess such as aromatic free class.Extruded aluminum tube is carried out oxide treatment, make it have superpower salt spray resistance, wet-hot aging performance, its antiseptic power is also far above the priming paint of other types.Simultaneously, seepage force is higher, has greatly improved the erosion resistance of aluminum tube surfaces.
