Wall body intelligent heat-insulation building envelope

Abstract

The invention discloses a wall body intelligent heat-insulation building envelope, which is characterized in that the building envelope comprises an outer wall thermal reflecting coating layer, a plaster layer, a foamed cement infrared-shielding heat-insulation layer, an adhesive layer, a wall body base material layer, an inner wall leveling mortar layer, a putty layer and a phase-change inner wall coating energy storage layer sequentially from outer side to inner side, wherein a glass fiber net layer is covered in the plaster layer. The outer surface of the outer wall thermal reflecting coating layer is coated with a photocatalyst purification layer. The arranged outer wall thermal reflecting coating layer has a heat-insulation effect, and meanwhile the arranged foamed cement infrared-shielding heat-insulation layer realizes integration of safe, energy-saving, durable, green and environment-friendly performances and has a better heat-insulation effect; the phase-change energy-storage building material has greater phase-change latent heat, and can store and release heat energy so as to realize an intelligent heat-insulation effect; finally, the outer surface is coated with the photocatalyst purification layer which has an outer wall purification and cleaning effect.

Description

technical field [0001] The invention relates to a wall structure, in particular to an intelligent wall thermal insulation enclosure structure. Background technique [0002] my country's energy saving started late, the awareness of energy saving is not strong, and the waste of energy consumption is very serious. Taking residence as an example, compared with developed countries with the same climate conditions, the external wall is generally 4 to 5 times, the roof is 2.5 to 5 times, and the external window 1.5 to 2.2 times, the air permeability of doors and windows is 3 to 6 times, and the total energy consumption is 3 to 4 times. [0003] The State Council, Development and Reform Commission, Ministry of Construction, State Environmental Protection Administration and other relevant departments put forward strict requirements that during the "Eleventh Five-Year Plan" period, building energy conservation should save 101 million tons of standard coal and reduce more than 400 milli...

Problems solved by technology

[0007] Although foamed cement has its unique advantages as a thermal insulation layer, not only has the advantages of high compressive strength, low thermal conductivity, stable chemical properties, environmental protection, and no change in shape, but foamed cement is not factory production. It needs to be operated and constructed on the construction site, so there are great differences in product quality. Some foamed cements cannot reach the due physical performance indicators at all, and the following problems mainly exist in the construction of the foamed cement: firstly, the foamed cement Excessive water consumption leads to a decline in the overall quality of foamed cement; secondly, excessive cement consumption prevents thermal insulation performance from being guaranteed; finally, the quality of foamed water is uneven and poor in stability

In addition, the common thermal insulation materials used in our country, such as EPS, XPS, polyurethane foam board, etc., are all organic materials. Although they have good thermal insulation performance, they not only have high refurbishment costs due to problems such as low fire resistance, poor durability, and high energy consumption in production. , and has brought a great security risk
