Problems solved by technology

[0003] At present, there are no targeted solutions for moisture-proof materials in China. The indoor moisture-proof treatment usually uses materials with water-resistant properties (such as: waterproof materials, waterproof mortar, water-resistant putty, water-resistant paint, water-resistant wallpaper, etc.) for so-called moisture-proof treatment. These materials can't solve the appearance of moisture at all, but only improve the water resistance of the material itself, but can't solve the condensation water formed by the condensation of indoor and outdoor air, and its essence can't fundamentally solve the moisture-proof problem

Abstract

The invention relates to a dampproof slab. The dampproof slab comprises a dampproof slab body, wherein the dampproof slab body comprises heat insulating layers, and a waterproof layer which is coated on two sides of the heat insulating layers. The dampproof slab is formed by combining a heat-insulating material and a waterproof material, wherein the heat-insulating material can be used for preventing the temperature of the surfaces of an architectural construction and a decorative covering from dropping, so that the surface temperature is higher than a dew point, and dew cannot be formed on the surfaces of the architectural construction and the decorative covering; the waterproof material has the functions of preventing extraneous moisture of a building from penetrating and protecting the heat insulating property of the heat-insulating material. Through the application of the dampproof slab, obvious water cannot be generated on the surfaces of the architectural construction and the decorative covering, so that the problem of generating dampness and mildew is fundamentally solved; the comfort of an interior space is improved, and the service life of the architectural construction and the service life of a decoration material are prolonged.

Description

technical field [0001] The invention relates to the field of industrial and civil buildings, in particular to a moisture-proof board that can solve the moisture problem caused by condensation and moisture penetration in buildings, including building floors, basements, and tunnels. Background technique [0002] Humidity problems on the indoor and outdoor structures and decorative surfaces of buildings are common, mainly caused by the condensation of water vapor in the air; secondly, it is caused by external penetration. [0003] At present, there are no targeted solutions for moisture-proof materials in China. The indoor moisture-proof treatment usually uses materials with water-resistant properties (such as: waterproof materials, waterproof mortar, water-resistant putty, water-resistant paint, water-resistant wallpaper, etc.) for so-called moisture-proof treatment. These materials can't solve the problem of moisture at all, but only improve the water resistance of the materi...
