Pressure-resistant, flame-retardant and waterproof asphalt roofing shingle

Abstract

The invention discloses a pressure-resistant, flame-retardant and waterproof asphalt roofing shingle, and belongs to the technical field of building waterproof materials. A flame-retardant layer is additionally arranged between a hydrophobic diversion layer and a glass fiber felt, and a plurality of flame-retardant cores are distributed between the flame-retardant layer and the glass fiber felt. Under normal conditions, the flame-retardant layer is matched with the flame-retardant cores, so that the pressure resistance of the asphalt roofing shingle is improved, and the asphalt roofing shingle can resist the impact of rainstorm to a certain extent. In case of an abnormal condition such as fire, external high temperature is transmitted to the flame-retardant cores through the hydrophobic diversion layer and heat-conducting anchoring nails, flame-retardant gas on the inner side of the flame-retardant cores is sprayed out from the heat-conducting anchoring nails to the hydrophobic diversion layer in a high-temperature and high-pressure environment, pores are generated in the hydrophobic diversion layer due to high temperature, the sprayed flame-retardant gas overflows in the hydrophobic diversion layer and is matched with vitrified rock particles to achieve a better flame-retardant effect, a fire source is blocked, and a fire extinguishing effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of building waterproof materials, in particular to a pressure-resistant and flame-retardant waterproof felt tile. Background technique [0002] Linoleum tiles have the characteristics of waterproof, decorative functions, rich colors, and easy construction. Mainly used for sloping roofs of residential and commercial buildings. At the end of the twentieth century, Shanghai and other coastal cities promoted "flat to slope", and colored asphalt tiles became the preferred roofing material, which not only changed the urban landscape, but also improved the drainage and heat insulation performance of the roof. The current promotion prospect of asphalt tiles is good. . [0003] The linoleum tile is a new type of sheet-shaped roof waterproof tile made of glass fiber felt as the matrix, after dip-coating high-quality petroleum asphalt surface, one side is covered with colored mineral particles, and the other side is ...

AI Technical Summary

Problems solved by technology

In the prior art, although the surface of asphalt tiles is supplemented with refractory mineral particles, the effect is negligible and it is difficult to solve the fundamental problem; and the impact resistance of the existing asphalt tiles needs to be improved
