Aluminum alloy template with self-lubricating film layer and processing method of aluminum alloy template

Abstract

The invention discloses an aluminum alloy template with a self-lubricating film layer and a processing method of the aluminum alloy template. The aluminum alloy template comprises an aluminum alloy template base material and the self-lubricating film layer formed on the surface of the aluminum alloy template base material. The self-lubricating film layer includes a carbon nano tube, nano polytetrafluoroethylene and nano SiO2, and the thickness of the self-lubricating film layer ranges from 40 micrometers to 60 micrometers. According to the aluminum alloy template, the Al2O3 / polytetrafluoroethylene composite oxidation film layer is formed on the surface of the aluminum alloy template through anodic oxidation, the self-lubricating function is achieved under the action of nano polytetrafluoroethylene, and the film layer is uniform and compact; corrosion resistance and friction hardness are high, and the friction coefficient is low; corrosion of cement can be borne, wear of concrete to the template in the pouring process can be reduced, the adhesion of the concrete on the surface of the template is weak, and the aluminum alloy template can be easily separated from a pouring object; and the flatness of a pouring wall body is high, after use, the building aluminum alloy template only needs to be cleaned with water, and the situation that a large quantity of manpower and releasing agents are put to remove cement attached to the building aluminum alloy template is not needed.

Description

technical field [0001] The invention relates to the technical field of building templates, in particular to an aluminum alloy template with a self-lubricating film layer and a processing method thereof. Background technique [0002] The building formwork is composed of a panel and a support system. The panel is the part that makes the concrete shape; the support system is the structural part that stabilizes the position of the panel and bears the upper load. The quality of the formwork is related to the quality of the concrete project, and the key lies in accurate size, firm assembly, tight joints, and convenient assembly and disassembly. Appropriate formwork should be selected according to the form and characteristics of the building structure in order to achieve good technical and economic results. [0003] With the development of the national economy and the gradual improvement of people's living standards, people's requirements for living and working places are also inc...

Problems solved by technology

1. The most traditional wood formwork, poplar wood formwork and pine wood formwork are more common. This kind of formwork is relatively light and the cost is slightly lower, but its strength is low, not waterproof, easy to mildew and rot, and the reuse rate is low. It needs to consume wood resources, which is not conducive to the protection of the ecological environment and forest resources; the disadvantage of bamboo formwork is that the reuse rate is low and it is not recyclable

2. Steel formwork, as the name implies, is made of steel, which is very strong and requires a large amount of release agent, and the construction progress is affected by the weather. After the formwork is removed, the concrete performance is very good but the weight is too heavy. The construction needs the assistance of mechanical equipment and is easy to rust , and it is easy to bond with the concrete during the concrete pouring process, it is difficult to demould, and it takes a lot of labor and materials

3. Plastic formwork, not afraid of water, durable, but poor rigidity, easy to change, and high cost

However, the existing aluminum alloy formwork also has the problems of the steel formwork. One is that the part combined with the concrete is easily corroded by the concrete. Affect the recycling of aluminum alloy formwork
