Inorganic A outer wall external heat-preserving reflective insulation system

Abstract

True heat preservation refers to warm keeping in winter and heat insulation in summer; and the realization of heat preservation needs heat insulation, and the form of heat insulation is heat preservation. Heat preservation and heat insulation of building design are decided by different preferred targets of design personnel, but absolute heat preservation which is not related to heat insulation does not exist. The invention relates to a pure inorganic A outer wall external heat-preserving reflective insulation system, which can be used for realizing outer wall external heat preservation of grade A in fire-protection rating through a mortar layer, and can be used for realizing a heat insulating function by reflecting sunlight rays through an inorganic finishing coat. A pure inorganic A five-in-one outer wall external heat-preserving reflective insulation system which is as long as a building in service life is characterized by consisting of: (1) a wall body layer, (2) a mortar layer having the functions of trowel finish leveling and heat-preserving and fire-proofing, (3) an anti-crack mortar layer of MU10 in compressive strength smeared instead of a gridding cloth protective layer according to design requirements, and (4) an inorganic coating layer with a heat reflection heat insulating effect and an energy-saving function for buildings.

Description

technical field [0001] The invention relates to a pure inorganic A-external wall thermal insulation reflective heat insulation system which can not only realize the functions of external thermal insulation of external walls and A-level fire prevention through the mortar layer, but also realize the thermal insulation function by reflecting sunlight through the decorative layer.

[0002] Conventional thermal insulation materials are mainly based on increasing void ratio, increasing thermal resistance, and reducing heat conduction. Various materials have different degrees of defects and deficiencies. Elevation, and the insulation layer is relatively thick; hard inorganic insulation materials are mostly profiles, with many joints, and the construction is not convenient. and other shortcomings; new thermal insulation materials such as vermiculite or diatomaceous earth or vitrified microbeads are mainly used to prepare lightweight thermal insulation mortar, which can be directly used as lightweight plastering mortar on various base wall materials. To a certain degree of thermal insulation effect, but this type of product has high requirements on the construction environment, under several conditions such as strong wind (>5 grade), direct sunlight, and low temperature (≤5°C), cracking will occur during construction

In addition, the construction process of this product is also relatively complicated, and it is necessary to put mesh cloth on the surface of the thermal insulation mortar or paint an additional protective layer and finishing layer to achieve good thermal insulation effect.
