Abstract

The invention discloses an inorganic hydrophobic heat preservation plate which comprises a plate body, wherein the plate body consists of a plurality of hydrophobic units; each hydrophobic unit comprises an inner core and a multi-layered outer housing completely covering the inner core; each inner core is formed by porous minerals; each outer housing at least comprises a cement layer and a sodium silicate layer completely covered with the cement layer. According to the inorganic hydrophobic heat preservation plate provided by the invention, the porous minerals are used for forming the inner cores of single-particle multi-layered housing structures as the porous minerals have stable physical and chemical properties and better expansibility, are generally used as base materials of the heat preservation plate and meet the requirements for inner cores; the outer housings at least adopt cement layers as cement is added with water to be stirred to be formed into slurry, can be hardened in air, is higher in strength after being hardened, is also resistant to fresh water or saline water erosion, and has the waterproofness and reinforcing effect; the outer housings also at least adopt sodium silicate layers as sodium silicate is high in binding force, higher in strength and excellent in acid resistance and heat resistance, and can be used as bonding layers between cement layers and porous minerals.

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...
