High-strength, high-insulation exterior wall heat-preservation face brick compounded by aluminum plastic and nanometer materials

Abstract

The invention provides an exterior wall heat-preservation face brick compounded by aluminum plastic and nanometer materials, belongs to the technical field of building materials, and particularly relates to the nanometer materials in application of building an exterior face wall heat-preservation system. The face brick is composed of an outer aluminum plate or aluminum-plastic plate layer, an adhesive layer and a basement heat-preservation layer made of inorganic lightweight materials mixed with nano-particles. The method for producing the face brick includes adding and uniformly mixing the nanometer materials with particle sizes at the nanoscale in a mixed system of cement, auxiliary cementing materials, high polymer adhesives, the inorganic lightweight materials, fibers and water, and pressurizing and molding the mixed system prior to being cross-linked by high polymer materials and hydration drying of the cement, adding the adhesive layer having adhesive function in the basement heat-preservation layer, and adhering the aluminum plate or aluminum-plastic plate to the adhesive layer. With the method, the exterior wall heat-preservation face brick is excellent in fireproof performance, high in crush resistance, tensile strength and adhesive strength and good in heat-preservation effect, and has very good decorative effect.

Description

technical field [0001] The technology belongs to the field of building materials, in particular to the application of nanometer materials in building exterior wall insulation systems. Background technique [0002] The development of energy-saving buildings is an important way to solve resource and energy problems. Taking China as an example, there are 44 billion square meters of existing buildings in China, and energy consumption is generally high. Building energy consumption generally accounts for 30% of the total energy consumption of the society, plus the consumption of the production process of building materials, the proportion of the total energy consumption of the society reaches 46% to 47%. Among them, the heating energy consumption per unit area of ​​buildings in the northern region is 1.5 to 2 times higher than that of European countries with similar climate conditions. Among the nearly 2 billion square meters of completed area each year, only 50 to 60 million sq...

Problems solved by technology

However, these materials are porous and have low strength. With the current production process, the strength of the external wall insulation board / brick made of these materials is correspondingly low, which can neither meet the engineering needs, but also easily cause safety hazards. In order to improve its strength, it is necessary to Adding excessive cementitious materials and auxiliary cementitious materials will greatly increase its thermal conductivity
