Problems solved by technology

Although the film-coated aluminum alloy formwork prepared by this method has a smooth surface after demoulding, it does not stick to concrete and does not react with concrete. During use, it was found that when the aluminum alloy formwork is used on site, it will often collide with each other, and it will also scratch the coating layer when other hard materials such as steel bars are pulled. These scratched parts are very easy to use. Corroded, after a period of use, the scratched parts need to be repaired, which slows down the turnover efficiency of the aluminum alloy formwork and increases the workload during construction

Abstract

The invention relates to the technical field of building materials, and discloses a film-coated aluminum alloy formwork and a film coating technology thereof.The construction face of an aluminum alloy formwork body is sequentially provided with an adhesion layer, a toughening layer and a high-strength lubricating layer; the technology comprises the steps that laser drilling is conducted on the aluminum alloy formwork, raw materials of the adhesion layer are heated to 190-200 DEG C, and the raw materials are evenly sprayed to the construction face of the aluminum alloy formwork; the raw materials of the toughening layer are heated to 190-200 DEG C and evenly sprayed to the construction face of the aluminum alloy formwork; mixing titanium-based/nickel-coated aluminum powder, aluminum oxide powder, graphite powder and polypropylene powder, heating to 190-200 DEG C, uniformly stirring, adding glycerol, uniformly stirring, naturally cooling to 70-80 DEG C, adding a defoaming agent, a dispersing agent and hydrophobic powder, stirring at 70-80 DEG C for 40-60 minutes, heating to 190-200 DEG C after stirring, spraying on the toughening layer, and drying to obtain the titanium-based/nickel-coated aluminum composite material. And then placing in an environment of 120-140 DEG C for standing. When the aluminum alloy formwork is scratched and rubbed, the aluminum alloy formwork has high toughness and hardness, and the risk that the construction face of the aluminum alloy formwork is scratched is reduced.

Description

Technical field [0001] The present invention relates to the technical field of building materials, in particular to a coated aluminum alloy template and a coating process thereof. Background [0002] Aluminum alloy formwork is a formwork suitable for concrete engineering made of aluminum alloy profiles as the main material, which is made by machining and welding. It is mainly composed of three parts system of aluminum panel, bracket and connector, with a complete set of common accessories for use, can be combined into different sizes of the complex overall mold base, is a kind of assembly, industrial construction of the system template, greatly improved the construction efficiency. [0003] During the construction process, aluminum alloy formwork will be affected by many climatic factors such as ultraviolet rays, rain, snow, frost, high temperature in summer, low temperature in winter, etc. in the natural environment, and is also susceptible to concrete erosion, impact, drag and ...
