Problems solved by technology

Although organic thermal insulation materials have the characteristics of small thermal conductivity [about 0.04w / (m·k)] and good thermal insulation performance, their fireproof performance is poor, generally B2 and B3, and the pollution is serious
Because these materials are prone to fire accidents in external insulation engineering, the industry building standards stipulate that the external insulation materials for civil buildings should be grade A or B1 in combustion performance, and for buildings with a height less than 24m, the combustion performance of the insulation materials should not be lower than B2 grade. Set up fire isolation belts, which greatly limits the application range of organic thermal insulation materials in external thermal insulation projects
Inorganic thermal insulation materials such as rock wool, glass wool, foam concrete, vitrified microspheres, etc., although the combustion performance reaches Class A, but the thermal conductivity is relatively high [0.07-0.08w / (m k)], and the thermal insulation performance is poor. It is difficult to achieve energy-saving indicators for external insulation projects
Traditional interior wall coatings have gradually withdrawn from the building materials market due to environmental protection and poor scrub resistance with the enhancement of people's awareness of environmental protection and the improvement of living aesthetics. Instead, water-based environmentally friendly interior wall coatings with low VOC content are used in large quantities. , while the thermal insulation of water-based environmentally friendly interior wall coatings needs to be improved
The traditional construction of internal and external walls is carried out separately, without considering whether the combination of internal and external wall materials and construction is energy-saving, resulting in low energy-saving performance of the wall

Abstract

The invention discloses a construction method for the heat-insulating wall body of a building. The method adopts the combined system of an inner wall heat-insulating decorative material and an outer wall heat-insulating decorative material for the wall body of the building, and comprises the following steps: plastering phase-change energy-storage inorganic / organic heat-insulating mortar, plastering phase-change energy-storage rendering mortar and mesh fabric, puttying phase-change energy-storage flexible water-fast putty, coating permeating-type elastic priming paint through rolling, and coating solar reflection heat-proof exterior wall coating through rolling on the outer wall of the wall body; plastering phase-change energy-storage desulphurized gypsum heat-insulating mortar, puttying temperature-regulating humidifying anti-bacterial flexible putty, and puttying temperature-regulating humidifying anti-bacterial interior wall coating on the inner wall of the wall body; and the like. Through the adoption of the construction method, the wall body has the functions of heat insulation, energy conservation, air purification, solar phase-change temperature adjustment, moisture absorption, moisture discharging, sound absorption, noise reduction, bacterium resistance, mold prevention, water prevention, and ventilation. Therefore, the method has the advantage that the functions of low carbon emission, pollution reduction, energy conservation, beautiful decoration and environment protection of the wall body are realized; and the method is convenient to popularize and apply.

Description

Technical field [0001] The invention relates to the technical field of civil buildings, in particular to a construction method for building thermal insulation walls. technical background [0002] Today, in the field of civil construction, it is a worldwide trend to realize resource conservation, energy conservation and emission reduction, ecological environmental protection, and low-carbon circular economy development model. At present, my country's existing construction area reaches 40 billion m 2 , an annual construction area of ​​3 billion m 2 Among them, high-energy buildings account for more than 95%, and the heating energy consumption per unit area is equivalent to 2-3 times that of developed countries with similar climate conditions. Building energy consumption has accounted for more than 30% of the total energy consumption of the society. There is a huge potential for building energy conservation. Therefore, my country has listed building energy conservation as one ...
