Embodiment 1

[0021] A transparent flexible layer with a thickness of 50 μm was formed on the upper surface of the No. 45 steel substrate by roller coating, and a transparent protective film layer of polytetrafluoroethylene with a thickness of 10 μm was arranged on the transparent flexible layer. The transparent flexible layer consists of 8.0wt% zinc powder, 10.0wt% zinc oxide, 5.0wt% nano zinc aluminum hydrotalcite, 2.0wt% aminoalkyltrimethoxysilane, 2.0wt% N-(2 -Mercapto-1-carboxyethyl) acrylamide, and the composition formed by the remainder acrylic resin.

Embodiment 2

[0023] A transparent flexible layer with a thickness of 50 μm was formed on the upper surface of the No. 45 steel substrate by roller coating, and a transparent protective film layer of polytetrafluoroethylene with a thickness of 10 μm was arranged on the transparent flexible layer. The transparent flexible layer is composed of 12.0wt% zinc powder, 8.0wt% zinc oxide, 4.0wt% nano zinc aluminum hydrotalcite, 2.0wt% aminoalkyltrimethoxysilane, 2.5wt% acrylic acid 2-mercapto -1-carboxyethyl ester, and the balance of acrylic resin composition.

Embodiment 3

[0025] A transparent flexible layer with a thickness of 50 μm was formed on the upper surface of the No. 45 steel substrate by roller coating, and a transparent protective film layer of polytetrafluoroethylene with a thickness of 10 μm was arranged on the transparent flexible layer. The transparent flexible layer is made of 10.0wt% aluminum, 10.0wt% zinc oxide, 5.0wt% nano zinc aluminum hydrotalcite, 2.0wt% aminoalkyltrimethoxysilane, 2.5wt% N-(2- Mercapto-1-carboxyethyl) acrylamide, and the remainder of the composition formed by acrylic resin.

Abstract

The invention relates to a building roof waterproof layer and belongs to the technical field of building technologies. The building roof waterproof layer comprises a metal substrate which is provided with a transparent flexible layer. A transparent protection layer is arranged on the transparent flexible layer which integrates the waterproof function and the function of providing cathode protection for the metal substrate. The transparent flexible layer can generate free electrons through light by means of the photoelectric effect. The building roof waterproof layer adopts the metal substrate with a cavity, so that an excellent heat preservation effect is achieved, and accordingly temperature control energy consumption in winter or summer can be reduced, and comfort is improved. The flexible layer adopted by the building roof waterproof layer integrates the waterproof function and the cathode protection function, the corrosion rate of the metal substrate can be greatly delayed, and the safety service life of a building roof can be prolonged remarkably. The building roof waterproof layer can be applied to roofs of commercial buildings such as markets and shopping centers, industrial buildings like industrial plants, and other buildings such as subways, airports and stations.

Description

technical field [0001] The invention relates to the technical field of automobile design and manufacture, more specifically, the invention relates to a building roof waterproof layer. Background technique [0002] The metal roof has the advantages of simple structure, light weight, safety, strong wind resistance, and safe, simple and fast construction, so it has been used in large-scale building roofs such as airports, railway stations, convention centers, gymnasiums, and small-area roofs such as villas. more and more applications. However, in order to obtain performances such as waterproofing, heat preservation and long life, the metal plates used are usually galvanized stainless steel plates, titanium plates, and copper plates, etc., and the price is relatively high; and if ordinary carbon steel is used, its service life is short. Contents of the invention [0003] In order to solve the above-mentioned technical problems in the prior art, the object of the present inven...
