Corrosion-resistant aluminum alloy door and window and preparation method thereof

Abstract

The invention discloses a corrosion-resistant aluminum alloy door and window and a preparation method thereof. The corrosion-resistant aluminum alloy door and window comprises an aluminum alloy door and window body, wherein the aluminum alloy door and window body is provided with a glass frame and a window frame; the glass frame is hinged to the window frame; an oxidation film, a resin-based composite material layer and a corrosion-resistant coating are sequentially arranged on the surface of the aluminum alloy door and window body from inside to outside; and the aluminum alloy door and windowbody comprises the following raw materials in parts by weight: 95-100 parts of aluminum, 1-3 parts of silicon powder, 2-5 parts of zinc powder, 2-5 parts of copper powder, 1-3 parts of magnesium powder, 0.5-1.5 parts of tin powder, 0.5-1.5 parts of strontium powder, 0.5-1.5 parts of manganese powder, 0.5-1.5 parts of iron powder and 0.5-1.5 parts of rare earth elements. According to the corrosion-resistant aluminum alloy door and window disclosed by the invention, some tin powder, strontium powder, manganese powder, iron powder and the like are added into the components of the aluminum alloydoor and window body, so that the mechanical properties of the aluminum alloy door and window body are effectively improved, and the tensile strength, corrosion resistance and strength effects of thealuminum alloy door and window body are remarkable; and the rare earth elements are added into the aluminum alloy door and window body, so that the casting fluidity of aluminum alloy liquid is improved, and the casting properties of aluminum alloy are improved.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy doors and windows, in particular to a corrosion-resistant aluminum alloy door and window and a preparation method thereof. Background technique [0002] Due to its light weight and high specific strength, aluminum alloys are widely used in various fields of national economy and national defense construction. At present, more door and window materials on the market are mainly aluminum alloy, color steel, and PVC materials, and aluminum alloy is favored by the market because of its high hardness, light weight, non-aging, beautiful and practical after color coating, and the market demand is increasing. more and more exuberant. However, at present, there is often a contradiction between the strength and casting performance of aluminum alloy profiles for doors and windows. When the alloy strength and toughness of aluminum alloy profiles meet the requirements, the casting performance is poor, wh...

Problems solved by technology

However, at present, there is often a contradiction between the strength and casting performance of aluminum alloy profiles for doors and windows. When the alloy strength and toughness of aluminum alloy profiles meet the requirements, the casting performance is poor, which is specifically manifested in the tendency of hot cracking and poor fluidity. , Feeding is difficult. In addition, aluminum alloy profiles with poor casting performance have poor corrosion resistance and tend to have intergranular corrosion. Aluminum alloy doors and windows will corrode when placed at room temperature for a long time, seriously affecting the service life of aluminum alloy doors and windows; with the development of modern industry and national defense, people put forward higher requirements for the quantity and quality of aluminum alloy materials, aluminum alloy doors and windows In the actual use process, there is a certain gap between the window frame and the glass frame of aluminum alloy doors and windows. Especially after long-term use, in rainy and snowy weather, rainwater and moisture can easily enter the room through the gap, which brings great harm to daily life. After the aluminum alloy doors and windows are used, insects in nature can easily fly into the room through the windows after the doors and windows are opened. The aluminum alloy doors and windows have relatively simple functions and cannot effectively repel mosquitoes. In order to meet the needs of people, in order to solve the above problems, a kind of corrosion-resistant aluminum alloy doors and windows and its preparation method are designed
