Title:
MANUFACTURING METHOD FOR POROUS WEATHER-RESISTANT AND ABRASION-RESISTANT SOUND-DEADENING COATING FOR EXTERNAL WALLS
Document Type and Number:
WIPO Patent Application WO/2021/051831
Kind Code:
A1
Abstract:
A porous weather-resistant and abrasion-resistant sound-deadening coating for external walls and a manufacturing method therefor. The porous weather-resistant and abrasion-resistant sound-deadening coating for external walls consists of three layers of structures. The bottom layer is a ceramic structure that is formed by mixing montmorillonite and kaolin according to a mass ratio of (3-3.5):(8-10) and then mixing the mixture and grid-like carbonized fibers under electrothermal pulse and penetrates into cement of a wall body; the middle layer is a mullite-like porous ceramic structure obtained by mixing silica micropowder, zircon powder, rutile powder, montmorillonite, and kaolin according to a mass ratio of (5-6):(0.2-0.3):(0.1-0.2):(21-24.5):(56-70) and then performing electrothermal pulse treatment; and the surface layer is a silica gel membrane. The coating has high water resistance, a high sound absorption coefficient, high weather resistance, a self pore-forming property, environmental friendliness, no pollution, and good wall surface adhesion.
