Thermal-insulating waterproof spray-coating building envelope structure

Abstract

The invention relates to a thermal-insulated waterproof sprayed protective structure, which is formed by a thermal-insulated layer and a protective layer above it. Wherein, said thermal-insulated waterproof layer is made by spraying the thermal-insulated waterproof liquid via foaming device on the main structural working surface of building; said thermal-insulated waterproof liquid contains multifunctional polyether polyatomic alcohol, polyester polyol mixture, mellow, sugar as initiator polyether polyatomic alcohol, ethanediamine as initiator polyether polyatomic alcohol, combustion inhibitor, foam uniform agnet, foaming agent, postassium acetate, triethylene diamine, acetal mixture, dibutyl dielaurate, ultraviolet adsorbent, and isocyanate; and the protective layer can be the common protective layer, strengthen protective layer, flameproof protective layer or the functional protective layer. The invention can save material, insulate heat, avoid leakage, and prolong the service life of building, etc.

Description

technical field [0001] The invention belongs to the technical field of buildings, in particular to a thermal insulation and waterproof spray coating enclosure structure of a building. Background technique [0002] Building energy conservation is a hot technical issue in the global construction industry, and it has a long way to go for our country. my country's construction market is the largest in the world, equivalent to the sum of Europe and the United States. my country's annual urban and rural construction area is about 2 billion square meters, of which 80% are high-energy buildings. The existing buildings are nearly 40 billion square meters, and more than 95% are high-energy buildings. Buildings make the energy supply more and more tense. The "leakage" of buildings has always plagued the construction industry and has always been a hot topic of concern. Leakage and seepage resistance is a technical problem in the construction industry. Building energy efficiency has led...

Problems solved by technology

All kinds of thermal insulation materials (such as porous bricks, aerated concrete, cement perlite, etc.) and waterproof materials (polymer organic materials) in China are single in performance and complicated in construction procedures. Building energy-saving projects and building waterproof projects are Separate design and separate construction, thermal insulation materials are not waterproof, waterproof materials are not thermal insulation, once the waterproof material leaks, thermal insulation materials will fail, and vice versa

[0003] The existing heat insulation structure usually has two kinds of heat insulation structures: roof and wall. The wall has inner and outer heat insulation structures. It is an internal heat insulation structure located on the inner side of the main structure of the building. When the internal heat insulation structure is used, the main structure of the building will be exposed to the natural environment. As a result, cracks and water leakage occur on the interior surface of the exterior wall, and due to the influence of "cold bridge heat festival", local condensation, humidity, and mildew occur, which in turn affects the performance of building energy conservation, people's living and living environment, etc.; When the external heat insulation structure is adopted, it is usually necessary to make the heat insulation layer and the finishing layer by drawing steel wire mesh and mechanical anchoring, etc., which not only results in a decrease in performance and an increase in cost, but also increases the construction cost. In addition, the current internal and external heat insulation structures are usually not waterproof, and a waterproof layer is required during production, resulting in cumbersome production processes and increased production costs.
