High self-cleaning inorganic heat insulation composite system

Abstract

The invention relates to a high self-cleaning inorganic heat insulation composite system comprising a substrate wall body, as well as interface mortar, a heat insulation layer, an anti-cracking protection layer and a veneer layer in sequence from the substrate wall body to the outside. The invention has the advantages of simple structure, comprehensive functions, favorable heat insulation effect, strong anti-cracking and shock resistance, obvious fireproof and antiflaming effect, favorable high temperature stability, high self-cleaning and the like. Anti-cracking mortar is selected for the anti-cracking protection layer and alkaline-resistant fiberglass gridding cloth or an AJ hot zinc-plating electrowelding net is arranged in the mortar, therefore, the anti-cracking and shock resistant effects are better; the polystyrene particles of the heat insulation layer are made from recycled polystyrene plates, therefore, the processing is simple, a large number of white pollution can be solved, and the heat insulation property of the material can be greatly improved due to excellent heat insulation property of the polystyrene particles per se; and an energy-saving coating material has the advantages of favorable visible light and near infrared light reflectivity, higher thermal infrared emissivity, excellent high temperature stability, high intensity, high temperature resistance, wear resistance, high tenacity, convenience for construction and cost saving.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a high self-cleaning inorganic thermal insulation composite system. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people have higher and higher requirements for the performance of buildings in all aspects. Whether the composite wall of the building has environmental protection and energy saving, sound insulation, heat insulation, fire prevention, earthquake resistance, and space utilization of the building is becoming more and more important. Whether the composite structure of the building wall is reasonable directly affects the above effects, and the rationality of the frame structure as the installation carrier of the composite wall panels also affects the above effects.

AI Technical Summary

Problems solved by technology

[0003] At present, the more common thermal insulation materials on the market mostly use polystyrene board, dense polystyrene board and thermal insulation mortar, which have many technical defects that are difficult to overcome and cannot really meet the thermal insulation requirements.

[0004] Polymer coating materials have penetrated into various sectors of the national economy and are an indispensable product for agriculture, industry and the tertiary industry. Environmental protection and energy saving are the main content of the national environmental protection and energy conservation policies. An important part of sustainable development, the existing coating materials in my country only have one or more of the functions of environmental protection, flame retardancy, and heat preservation, and rarely have self-cleaning functions, and there are a small number of coating materials with self-cleaning functions , it is also difficult to have the functions of environmental protection, flame retardancy and heat preservation at the same time

Although some technologies have a self-cleaning function, they are limited to the self-cleaning effect of the wall dust through the rainwater, and there is nothing that can be done to the oil stains attached to the wall and the dust on the oil stains.
