Description

TECHNICAL FIELD

[0001] The utility model belongs to building decoration material technical field, concretely relates to a self -cleaning aluminium veneer. BACKGROUND

[0002] In the field of building decoration and curtain wall, aluminium veneer is widely used as a common decoration material. However, in the process of use, dust, stains and other pollutants are easy to accumulate on the surface of aluminium veneer, especially in outdoor environment, the adhesion of pollutants is more prominent under the influence of natural environmental factors such as wind sand, rainwater, bird droppings and the like. These pollutants not only affect the appearance of aluminium veneer and reduce the overall appearance quality of the building, but also may cause corrosion on the surface of aluminium veneer and shorten its service life. The traditional cleaning method of aluminium veneer mainly relies on manual regular cleaning, which not only needs to consume a lot of manpower, material resources and time cost, but also has great safety risk in manual cleaning on some high-rise buildings or complex structure buildings, and it is difficult to achieve timely cleaning work.

[0003] Therefore, it is urgent to provide a self-cleaning aluminium veneer to solve the problems in the background art. SUMMARY

[0004] The utility model aims at providing a self-cleaning aluminium veneer to solve the technical problem that the traditional cleaning method of aluminium veneer mainly relies on manual regular cleaning, which not only needs to consume a lot of manpower, material resources and time cost, but also has great safety risk in manual cleaning on some high-rise buildings or complex structure buildings, and it is difficult to achieve timely cleaning work.

[0005] In order to solve the above technical problems, the utility model provides a self-cleaning aluminium veneer, which comprises: an aluminium veneer body, a plurality of first inclined grooves and second inclined grooves are arranged on the aluminium veneer body, the first inclined grooves and the second inclined grooves are symmetrical to each other and uniformly distributed on the surface of the aluminium veneer body, the outer surfaces of the first inclined grooves and the second inclined grooves are all trapezoidal, and the upper end opening is longer than the lower end opening, and the inclination angles of the two inclined sides of the trapezoidal of the first inclined groove are 50° and 60° respectively.

[0006] As a further elaboration, the upper end of the first inclined groove and the second inclined groove is deeper than the lower end.

[0007] As a further elaboration, the surface of the aluminium veneer body and the first inclined groove and the second inclined groove is provided with a composite lubricating layer.

[0008] Compared with the prior art, the utility model has the advantages of:

[0009] 1. The first and second inclined grooves are symmetrically arranged on the aluminum veneer body, and the upper end of the trapezoidal groove is longer than the lower end, forming a flow guide structure to enhance the scouring effect of water flow or air flow, making it easier for pollutants to slide off and improving the self-cleaning efficiency by more than 40% (referring to GB / T 9780-2013 test standard). This unique structure makes it difficult for pollutants to attach smoothly on the surface. By calculating the maximum rainwater scouring efficiency and the critical angle of dust sliding, the two inclined angles of the trapezoidal first inclined groove are set to 50° and 60°, respectively. When encountering natural wind, rainwater scouring and other conditions, pollutants are more likely to slide down along the inclined angle of the inclined groove, greatly improving the possibility of natural detachment of pollutants compared to traditional flat aluminum veneer, reducing the frequency of manual cleaning.

[0010] 2. The upper end of the first and second inclined grooves is deeper than the lower end, and this upper-deep and lower-shallow groove design forms a "funnel"-like structure. Under the action of natural forces, pollutants entering the deeper upper end of the groove will more easily slide along the inclined and gradually shallower groove bottom, and are less likely to accumulate in the groove, thereby effectively improving the discharge efficiency of pollutants and keeping the surface of the aluminum veneer clean.

[0011] 3. The surface of the aluminum veneer body and the first and second inclined grooves is provided with a composite lubricating layer, which has a low surface friction coefficient and can significantly reduce the adhesion between the pollutants and the surface of the aluminum veneer. This makes it more difficult for pollutants to adhere firmly when they come into contact with the surface of the aluminum veneer, further promoting the natural detachment of pollutants, reducing the corrosion of pollutants on the surface of the aluminum veneer, effectively prolonging the service life of the aluminum veneer, and maintaining the cleanliness and beauty of the building appearance.

[0012] Other features and advantages of the present application will be set forth in the following description of the application, and in part will become apparent to those skilled in the art upon examination of the following or can be learned by practice of the application.

[0019] To make the purpose, technical scheme and advantage of the utility model embodiment clearer, the technical scheme of the utility model will be described clearly and completely below in conjunction with the drawings, obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the scope of protection of the utility model.

[0020] Referring to Figs. 1-2 A self-cleaning aluminum veneer, comprising: an aluminum veneer body 1, a plurality of first inclined grooves 2 and second inclined grooves 3 are arranged on the aluminum veneer body 1, the first inclined grooves 2 and the second inclined grooves 3 are symmetrical to each other and uniformly distributed on the surface of the aluminum veneer body 1, the outer surfaces of the first inclined grooves 2 and the second inclined grooves 3 are all trapezoidal, and the upper end opening is longer than the lower end opening, and the inclination angles of the two inclined sides of the trapezoidal first inclined grooves 2 are 50° and 60° respectively. The first inclined grooves 2 and the second inclined grooves 3 are arranged on the aluminum veneer body 1, and the upper end opening of the trapezoidal groove is longer than the lower end opening, forming a flow guide structure, enhancing the scouring effect of water flow or air flow, making the pollutants more easily slide off, and the self-cleaning efficiency is improved by more than 40% (referring to GB / T 9780-2013 test standard). This unique structure makes it difficult for pollutants to adhere smoothly on the surface; by calculating the rainwater scouring efficiency maximization and the dust sliding critical angle, the inclination angles of the two inclined sides of the first inclined grooves 2 are set to 50° and 60° respectively, when encountering natural wind force, rainwater scouring and other conditions, the pollutants are more easily slide off along the inclined angle of the inclined groove, compared with the traditional flat surface aluminum veneer, the possibility of natural falling off of the pollutants is greatly improved, and the frequency of manual cleaning is reduced.

[0021] As Figs. 1-2 shown, the upper end of the first inclined groove 2 and the second inclined groove 3 is deeper than the lower end. This upper-deep and lower-shallow groove design forms a structure similar to a "funnel". Under the action of natural force, the pollutants entering the deeper upper end groove will more easily slide along the inclined and gradually shallow groove bottom, and are not easy to accumulate in the groove, thereby effectively improving the discharge efficiency of the pollutants and keeping the surface of the aluminum veneer clean.

[0022] As Figs. 1-2As shown, the surface of the aluminum veneer body 1 and the first chute 2 and the second chute 3 is provided with a composite lubricating layer. The composite lubricating layer contains graphene nanosheets and molybdenum disulfide particles, wherein the content of graphene is 0.3-1wt%, and the content of molybdenum disulfide is 1-2wt%. The lubricating layer has a low surface friction coefficient, and can significantly reduce the adhesion between pollutants and the surface of the aluminum veneer. This makes it more difficult for pollutants to firmly adhere when they come into contact with the surface of the aluminum veneer, further promoting the natural shedding of pollutants, reducing the corrosion of pollutants on the surface of the aluminum veneer, effectively prolonging the service life of the aluminum veneer, and maintaining the cleanliness and beauty of the building appearance.
