Abstract

The invention discloses an inorganic water-repellent thermal insulation board, which comprises a board body, the board body is composed of several water-repellent units, the water-repellent unit includes an inner core and a multi-layer outer shell completely wrapping the inner core, the inner core is porous mineral, and the outer shell at least includes cement layer and the sodium silicate layer completely wrapped within the cement layer. The porous mineral of the present invention is used to form the core of a single-particle multi-layer shell structure. Because the porous mineral has stable physical and chemical properties and good expansion performance, it is often used as the base material of the insulation board and meets the requirements of the core. At least the cement layer is selected for the shell, because the cement is mixed with water to form a slurry, which can be hardened in the air. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water, and has the functions of water resistance and reinforcement. At least the sodium silicate layer is selected for the outer shell. The sodium silicate has strong cohesive force, high strength, good acid resistance and heat resistance, and can be used as a bonding layer between the cement layer and the porous mineral.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to mortar containing reaction products of inorganic binders. Background technique [0002] In order to realize the insulation of buildings, it is necessary to install insulation boards on the outer walls of buildings. The existing insulation board materials can be divided into organic and inorganic materials. When organic materials and inorganic materials are used as outer wall insulation boards, there are certain Disadvantages: The flame retardancy of organic materials is poor, and the water absorption rate of inorganic materials is high. Therefore, the applicant thought of improving the hydrophobicity of the porous mineral (a kind of inorganic material) so that it can meet the requirements of being an inorganic insulation board material for external walls. [0003] The previous invention patent with publication number "CN 102448719B" titled "Hydrophobic Material Prepar...
