Light pitched roof waterproof tile and preparation method thereof

Abstract

The invention relates to a light pitched roof waterproof tile comprising a first fiber layer, a composite layer and a second fiber layer which are fixedly connected in sequence from the bottom layer to the top layer. The composite layer comprises a reinforcing layer. The first fiber layer and the second fiber layer are each prepared from basic fiber, reinforced fiber and a paper board water repellent agent. The reinforcing layer is a cotton and bast fiber layer or a glass fiber layer, a metal wire layer or a wool fabric material layer. The first fiber layer, the composite layer and the second filter layer are steeped with modified asphalt. The pitched roof waterproof tile has high strength, toughness and impact resistance, not probe to cracking or damage in the installation and using process, good in waterproof effect, not prone to color fading or losing, and capable of being decomposed, recycled and repeatedly used. The invention further relates to a preparation method of the light pitched roof waterproof tile. The preparation method comprises the steps of raw material preparation, body material manufacturing, body material shaping and body material steeping. The method is high in production efficiency, safe in production process and suitable for batch production.

Description

technical field [0001] The invention belongs to the field of waterproof building materials, and in particular relates to a lightweight sloping roof waterproof tile and a preparation method thereof. Background technique [0002] At present, light waterproof materials for sloping roofs in my country mainly use tile materials combined with plant fibers and cement, such as asbestos cement tiles. The asbestos cement tiles have low strength and no toughness; or use tile materials combined with plant fibers and asphalt, such as linoleum. Asphalt tiles or asphalt tiles, the length of the fibers contained in the asphalt tiles or asphalt tiles is relatively short, and the bonding force between the fibers and the asphalt is low, so that the overall strength of the asphalt tiles or asphalt tiles is low, and the fibers in the tiles are prone to peeling off from the matrix. question. When the external force is applied during the construction process, or when the external temperature change...

[0002] At present, light waterproof materials for sloping roofs in my country mainly use tile materials combined with plant fibers and cement, such as asbestos cement tiles. The asbestos cement tiles have low strength and no toughness; or use tile materials combined with plant fibers and asphalt, such as linoleum. Asphalt tiles or asphalt tiles, the length of the fibers contained in the asphalt tiles or asphalt tiles is relatively short, and the bonding force between the fibers and the asphalt is low, so that the overall strength of the asphalt tiles or asphalt tiles is low, and the fibers in the tiles are prone to peeling off from the matrix. question

When the external force is applied during the construction process, or when the external temperature changes and the internal stress is generated inside the tile, the tile material is prone to cracks, and even the problem of tile breakage occurs, causing the tile material to lose its waterproof effect. , the broken part may even fall off from the top of the sloping roof, causing a safety hazard

At the same time, most commonly used waterproof materials change their color by spraying paint on the surface. The paint is difficult to penetrate into the interior of the waterproof tile material and only floats on the surface. In the natural environment, due to various erosions such as wind, sun, rain, etc. effect, there will be fading and fading of the tile material
