Abstract

The invention discloses a modification method for aluminum proximate matter for a building. The modification method comprises the steps that zinc powder, magnesium powder, ganister powder, iron blocks, rhenium ingots, titanium ingots, boron powder, copper blocks, indium ingots, chromium powder and cerium ingots are smelted to obtain alloy liquid, aluminum zirconium wrapped titanium dioxide and zirconium wrapped silicon dioxide mixed powder is added, then pouring into a die is carried out, and a casting is subject to heat treatment to obtain the aluminum proximate matter; a modifying agent is prepared and comprises the following raw materials including sodium fluoride, ammonium bifluoride, potassium permanganate, sodium dimethylnaphthalene sulfonate, polychlorinated polyethylene, potassiumchromate, zinc phosphate, sodium nitrate, praseodymium chloride, edetic acid, malic acid, sodium dodecyl benzene sulfonate, nickel sulfate, triethanolamine, zinc phosphate, magnesium oxide, nanometertitania, a silane coupling agent KH-570, chlorinated polypropylene and water; and then the modifying agent is used for enabling the aluminum proximate matter to be subject to two times of soaking andtwo times of drying to obtain the modified aluminum proximate matter. The aluminum proximate matter prepared through the method has the excellent high temperature corrosion resisting property.

Description

【Technical field】 [0001] The invention belongs to the technical field of aluminum profile preparation, and in particular relates to a method for modifying aluminum profiles for construction. 【Background technique】 [0002] The aluminum profile titanium plating process belongs to the coating technology. It adds pre-plating and electroplating process steps on the basis of the conventional titanium plating process. The aluminum profile process is to place the activated plated parts in an aqueous solution of salt and hydrochloric acid for chemical treatment. Although aluminum profiles have certain anti-corrosion properties, their anti-corrosion properties cannot meet the requirements of anti-corrosion properties under high-temperature conditions during use. [0003] Chinese patent application document "A method for modifying aluminum profiles for construction (application publication number: CN103820776A)" relates to the modification of aluminum profiles, in particular to a meth...
