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

Abstract

The invention relates to a metal and asphalt composite tile for a special-shaped roof, comprising an asphalt base layer and a metal layer provided with a surface coating, wherein a bonding layer usedfor bonding the metal layer provided with the surface coating and the asphalt base layer is arranged between the asphalt base layer and the metal layer provided with the surface coating, and a protective film is arranged on the lower portion of the asphalt base layer. The metal and asphalt composite tile has the beneficial effects that the metal and asphalt composite tile has great advantages in the aspects of flexibility, a fixing mode, light weight and rich colors, and is very suitable for being applied to special-shaped roofs, such as spherical roofs and conical roofs; the bonding layer isarranged between the asphalt base layer and the metal layer provided with the surface coating, so that the metal layer provided with the surface coating is firmly bonded with the asphalt base layer; by arranging the surface coating, the effects of protecting the metal layer provided with the surface coating and decorating are achieved; a flanging used for wrapping the asphalt base layer is arranged on the metal layer provided with the surface coating, so that the waterproof material is prevented from being directly exposed in the sun and rainwater to accelerate the aging of the waterproof material.

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.

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
