Problems solved by technology

Since the 1990s, some people have used it in metal surface protection, and found that silane coupling agent has a better metal protection effect, but the silane superhydrophobic film is uniform and dense, which can effectively prevent the invasion of corrosive media, but this The durability of the film-like layer is poor, and once it is damaged, the entire film layer will quickly fail. As a catho

Embodiment Construction

[0012] A water-based cleaning agent for the surface of aluminum profiles, prepared from the following raw materials in parts by weight (kg): benzotriazole 0.5, cerous nitrate 5, sodium fluoride 1, hydrogen peroxide 1.5, vinyl triethoxy Silane 20, polyvinyl alcohol 1, nano-titanium dioxide 1, nano-zirconia 2, water-based polyurethane 5, maleic anhydride 2, lanthanum nitrate 0.6, octylisothiazolinone 0.2, fenugreek gum 0.3, propylene alcohol 0.7, Stalactite powder 0.6, deionized water 100.

[0013] The water-based cleaning agent for the surface of aluminum profiles is prepared through the following specific steps:

[0014] (1) Mix vinyltriethoxysilane, deionized water and absolute ethanol evenly according to the volume ratio of 5:5:90, then drop in acetic acid to adjust the pH value to 6.5, stir and hydrolyze at room temperature for 48 hours for later use;

[0015] (2) Dissolve polyvinyl alcohol with 5 times the amount of deionized water, add nano-titanium dioxide and nano-zirc...

Abstract

The invention discloses a water-based cleaning agent for the surface of an aluminum profile. The water-based cleaning agent is prepared from, by weight, 0.5-1 part of benzotriazole, 5-6 parts of cerous nitrate, 1-2 parts of sodium fluoride, 1.5-2 parts of hydrogen peroxide, 20-24 parts of triethoxyvinylsilane, 1-2 parts of polyving akohol, 1-2 parts of nanometer titania, 2-3 parts of nanometer zirconium dioxide, 5-6 parts of waterborne polyurethane, 2-3 parts of maleic anhydride, 0.6-0.8 part of lanthanum nitrate, 0.2-0.3 part of OIT, 0.3-0.5 part of trigonella bean gum, 0.7-1 part of allyl alcohol, 0.6-0.8 part of stalactite powder and 100-130 parts of deionized water. The water-based cleaning agent is low in cost, simple in preparing process and short in film formation time; the surface of a film layer is even and flat, and the bonding force on an aluminum alloy base body is good; and the corrosion resistance of the aluminum alloy surface can be improved well, and the environment or equipment is not polluted.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a water-based cleaning agent for the surface of aluminum profiles. Background technique [0002] Aluminum is one of the most widely used non-ferrous metals. It has the characteristics of light weight, high mechanical performance, good thermal and electrical conductivity, and corrosion resistance in the atmosphere. It is widely used in petroleum, aviation and light industry and other fields. Due to the relatively active nature of aluminum, a dense aluminum oxide film is formed on the surface when high temperature is applied during the forming process. At the same time, aluminum alloy profiles will be contaminated with a lot of oil, dust and other pollutants during transportation and storage. The presence of the molten metal will hinder the good combination between the formation of inclusions, while absorbing moisture in the air to destroy the continuity and uniformity o...
