Super-hydrophobic corrosion-resistant composite tile and method for manufacturing same

Abstract

The invention discloses a super-hydrophobic corrosion-resistant composite tile and a method for manufacturing the same. The super-hydrophobic corrosion-resistant composite tile comprises a color steelsurface layer, a polyurethane foam core, a color steel bottom layer, a top hydrophobic layer and a bottom hydrophobic layer. The top hydrophobic layer and the bottom hydrophobic layer cover the uppersurface and the lower surface of the color steel surface layer, the top surface of the polyurethane foam core is adhered on the lower side of the bottom hydrophobic layer, and the bottom surface of the polyurethane foam core is adhered on the upper surface of the color steel bottom layer; the thickness of the color steel surface layer ranges from 0.1 cm to 0.5 cm; the thickness of the polyurethane foam core ranges from 1.0 cm to 5 cm; the thickness of the color steel bottom layer ranges from 0.3 cm to 1.0 cm; the thicknesses of the top hydrophobic layer and the bottom hydrophobic layer rangefrom 0.3 micrometer to 10 micrometers; the top hydrophobic layer and the bottom hydrophobic layer 5 are made of alodine liquid, fluorine-containing polyurethane, dimethylbenzene and nanometer SiO2; the thickness of the super-hydrophobic corrosion-resistant composite tile ranges from 1.5 cm to 5 cm. The super-hydrophobic corrosion-resistant composite tile and the method have the advantages that thehydrophobicity and the corrosion resistance of the super-hydrophobic corrosion-resistant composite tile can be enhanced, and the service life of the super-hydrophobic corrosion-resistant composite tile can be prolonged.

Description

technical field [0001] The invention relates to the field of civil construction, in particular to a superhydrophobic, corrosion-resistant and long-life superhydrophobic corrosion-resistant composite tile and a manufacturing method thereof. Background technique [0002] With the continuous development of my country's economy in recent years, it has promoted the development of the construction industry. Modern buildings are gradually developing towards high quality and high grade, and their functional requirements are constantly improving. Traditional roofing materials can no longer meet the requirements of the development of the construction industry, and various new materials have emerged as the times require. [0003] The commonly used roofing materials are: asbestos tiles, cement tiles, composite tiles, etc. Among them, asbestos tiles not only contain carcinogenic ingredients, but also have a short service life, are perishable, and have certain pollution to the environmen...

AI Technical Summary

Problems solved by technology

Among them, asbestos tiles not only contain carcinogenic ingredients, but also have a short service life, are perishable, and have certain pollution to the environment; cement tiles have disadvantages such as complex construction, heavy structure, water absorption and water seepage; and composite tiles that have emerged in recent years have excellent load-bearing capacity. Light weight and other advantages, but usually weak in waterproof and corrosion resistance
