Metal and asphalt composite tile for special-shaped roof and preparation method thereof

Abstract

The invention relates to a metal and asphalt composite tile for special-shaped roofs, comprising an asphalt base and a metal layer with a surface coating, and a surface for bonding is provided between the asphalt base and the metal layer with a surface coating. The bonding layer between the metal layer of the coating and the asphalt base, and the lower part of the asphalt base is provided with a protective film. Its beneficial effects are: the present invention has great advantages in terms of flexibility, fixing method, light-weight property and rich colors, and is very suitable for the application of special-shaped roofs, such as curved roofs such as spherical surfaces and conical surfaces; An adhesive layer is provided between the metal layers with surface coating to make the metal layer with surface coating and the asphalt base firmly bonded; by providing a surface coating, the metal with surface coating can be protected The role of layer and decoration; through the metal layer with surface coating, there is a flange for wrapping the asphalt base layer, so as to avoid the waterproof material from being directly exposed to the sun and rain to accelerate its aging.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a metal and asphalt composite tile for special-shaped roofs and a preparation method thereof. Background technique [0002] my country's urban and rural construction is developing rapidly, and the construction area of ​​houses built every year in the country has reached 1.6-1.9 billion square meters 2 , while the existing construction area in urban and rural areas across the country has exceeded 36 billion m 2 , of which only 140 million m 2 , Building energy consumption has accounted for 27.8% of the country's total energy consumption, so building energy conservation is necessary for the development of my country's buildings. [0003] The traditional roof tiles are usually made of clay. The roof tiles made of clay are only for decoration. Not only is the color monotonous, but the installation and laying of the roof tiles on the roof is more complicated and the const...

Problems solved by technology

[0003] The traditional roof tiles are usually made of clay. The roof tiles made of clay are only for decoration. Not only are the colors monotonous, but also the installation and laying of the roof tiles on the roof is cumbersome and the construction period is long; (The performance of roof tiles in terms of waterproofing can not meet the requirements of the construction industry; the safety of asphalt tiles is not strong, and the aging is serious; the style of color steel composite panels is monotonous; because the variety and quality of domestic coatings cannot fully meet the requirements, the cost of imported coatings is too high. At present, there is a lack of composite boards with thick coating, good functionality, high strength and rich colors

[0004] Moreover, when constructing special-shaped roofs, such as spherical and conical surfaces, traditional hard tiles, such as terracotta tiles, cement tiles, and metal tiles, cannot change with the curved surface of the roof. Therefore, traditional hard tiles should be used to make The roof cannot meet the design requirements, and its fixing method is very hidden and dangerous
