Outer wall heat insulation face brick with glaze-imitating surface and preparation method thereof

Abstract

The invention claims an outer wall heat insulation face brick with a glaze-imitating surface and a preparation method thereof. The outer wall heat insulation face brick consists of a heat insulation layer basal body and a glaze-imitating surface layer integrated with the heat insulation basal body into a whole, wherein the glaze-imitating surface layer is prepared from phthalic anhydride-propanediol resin, silicon oxide particle, Portland cement, silica solution, inorganic short fibre, stearic acid, ammonium persulfate, benzoin, nanoscale titanium oxide superfine micro powder and nanoscale silicon oxide superfine micro powder. The preparation method ensures that the heat insulation layer and a decorative layer are firmly bonded, has high intensity and can effectively prevent the decorative layer from cracking and falling off; and besides, the decorative layer has the advantages of light weight, ageing resistance, long service life, water and moisture protection, good appearance effect, energy saving, environment protection, resource saving, and the like.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building walls, and relates to an imitation glazed external wall thermal insulation facing brick and a preparation method thereof. Background technique [0002] With the further standardization of the "standards" for energy-saving design of civil buildings and the implementation of the State Council's "Regulations on Energy Conservation of Civil Buildings", higher requirements are put forward for new building materials and wall insulation systems, which require both good thermal insulation performance and It has outstanding compressive, tensile, and anti-aging properties; it must not only have reliable protective properties to fundamentally block fire hazards, but also have the characteristics of waterproof, impermeable, and permanent service life; it must be green and environmentally friendly, non-toxic and non-toxic. Harmful, but also beautiful and elegant, decorative en...

Problems solved by technology

At present, most of the external wall decoration materials sold in the market are coated with paint on the thermal insulation wall for protection and decoration. This kind of paint layer has poor heat insulation, waterproof and self-cleaning performance, and is easy to be contaminated with dust and stains. The decorative effect is not ideal, especially the anti-aging performance is poor. Generally, fading or discoloration, wrinkling and other problems will appear in 3 to 5 years. The service life is short and the maintenance is difficult.

In addition, there is another problem that is difficult to overcome, that is, the construction procedure is complicated and the quality of the construction link is difficult to control, which makes it difficult to guarantee the quality of the external wall project.

Some use bonded ceramic tiles as the decorative protective layer, and their decorative protective performance has been improved to varying degrees. However, the bonding fastness between the heat insulation layer and the decorative protective layer in this way is poor, and the weight of the surface tiles is relatively large. It not only increases the overall weight of the wall, but also is easy to crack and fall off, bringing various adverse consequences
