Light roofing system

Abstract

A light roofing system is formed of a substrate layer and a waterproof surface layer. The waterproof surface layer comprises a functional coating layer made of functional paint and a waterproof layer made of waterproof paint, the functional paint comprises a base material and functional materials, and the functional materials comprise an inorganic flaky material, an inorganic high-rigidity wear-resistant material, and polymer powder with good toughness. The addition amount of the inorganic flaky material accounts for 1% to 8% of the total weight of the functional paint, the addition amount of the inorganic high-rigidity wear-resistant material accounts for 2% to 15% of the total weight of the functional paint, and the addition amount of the polymer powder with good toughness accounts for 1% to 8% of the total weight of the functional paint.

Description

technical field [0001] The invention relates to the technical field of roof structures, in particular to a light roof system with simple structure. Background technique [0002] In recent years, the energy crisis has intensified globally and has become a major theme for the sustainable development of countries and societies. Building energy consumption accounts for about 30% of the total energy consumption in developed countries. Under the general situation of energy conservation and emission reduction, the demand for energy conservation in engineering construction continues to increase. [0003] Such as figure 1 As shown, the existing building roof system, such as the master roof in the "Building Standard Design Architecture Atlas of Central and Southern Regions", consists of a base material layer 1, a slope layer 2, a leveling layer 3, a waterproof layer 4, and heat insulation Layer 5, isolation layer 6, protective layer 7, decorative layer 8 and other multi-layered and ...

AI Technical Summary

Problems solved by technology

[0004] 1. Due to the multi-layer structure composed of various materials, the construction process is complicated and cumbersome, the material consumption is large, the construction period is long, and professional construction personnel are required, so the cost is high;

[0005] 2. Since most of the materials used are mortar, waterproof coiled material, waterproof coating, thermal insulation materials and other construction materials, the load-bearing structure of the house has a heavy burden, and the consumption of steel reinforcement materials and energy and building materials during the construction process are large;

[0006] 3. The multi-layer superimposed structure of different materials is adopted. Due to the inconsistent expansion coefficients of the materials of each layer, it is easy to cause roof cracking and water leakage;

Once the roof structure is damaged artificially or naturally, it is difficult to check and detect. It can only be removed as a whole and resurfaced, which consumes a lot of resources and high maintenance costs;

[0008] 5. Existing roofing systems need to consume a lot of non-recyclable materials during construction and maintenance, and generate a lot of construction waste, which not only consumes excessive resources, but also causes damage to the environment;

[0009] 6. Most of the materials used in the existing roofing system contain flammable materials, especially waterproof and thermal insulation materials, which may even produce toxic smoke when burned, posing a great safety hazard
