Problems solved by technology

[0003] However, this kind of coating has several major defects: first, the construction equipment and construction technology requirements are high, the implementation cost is high, and the quality is unstable; Beautiful; the third is that the surface of this coating is uneven, and because the coating itself is low in strength, not wear-resistant, it is easily damaged by external forces; the fourth is that the sound absorption coefficient is low, which can only be compensated by thickening the coating thickness (generally about 5mm), It leads to poor adhesion on the wall; fifth, the paint itself is alkaline, and it is easy to burn people's skin during construction, and it is not resistant to acid rain and ultraviolet rays in daily use, so its use is limited

Embodiment 1

[0024] ①Mix 320kg of montmorillonite and 930kg of kaolin evenly, add 250kg of polyvinyl alcohol aqueous solution with a concentration of 2%, heat to 52°C-55°C, and stir them evenly to obtain wet heat clay;

[0025] ②Apply 450kg of hot and humid clay evenly on the surface of the exterior wall with a coating thickness of 0.5mm-1mm, and then let it stand for 2 days on a sunny day. Until porosity and cracks appear on the coating surface;

[0026] ③ Evenly spray the root canal algae spore concentration of 1 × 10 on the dry cracked coating surface 6 cfu / ml-1×10 8 Cfu / ml of seawater until the average water content of the coating rises to 30%-40%, and then continue to sprinkle water every half an hour to maintain humidity until the coating is covered with brown moss-like algae;

[0027] ④Bake the paint with an open flame until the paint dries again, and the brown moss is carbonized into a black fluff-like substance, and spread 40kg of aluminum wire 4 with a diameter of 0.1mm-0.5mm o...

Abstract

The invention discloses porous weather-resistant abrasion-resistant sound-proof paint for external walls and a manufacturing method of the paint. The porous weather-resistant abrasion-resistant sound-proof paint for the external walls is composed of a three-layer structure, wherein the bottom layer is a ceramic structure which is formed by mixing montmorillonite and kaolin according to a mass ratio of (3-3.5):(8-10), mixing the obtained mixture and grid-like carbonized fibers and performing electric heating pulse and extends into wall body cement; the middle layer is a mullite-like porous ceramic structure obtained by mixing silicon dioxide 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 performing electric heating pulse treatment; and the surface layer is a silica gel membrane. The paint has the advantages of high water resistance, a high sound absorption coefficient, high weather resistance, self pore forming, environmental protection, no pollution, and good binding force with the walls.

Description

technical field [0001] The invention relates to the technical field of environmental protection coatings, in particular to a method for manufacturing a porous weather-resistant, wear-resistant and sound-insulating coating for exterior walls. Background technique [0002] The sound-proof coatings in the prior art, also known as sound-absorbing coatings, generally use biological fibers, mineral fibers, etc. It is sprayed out and attached to the inner roof and wall to form a cotton-like coating material with a thickness of 2-10 mm and apparently porous. [0003] However, this kind of coating has several major defects: first, the construction equipment and construction technology requirements are high, the implementation cost is high, and the quality is unstable; Beautiful; the third is that the surface of this coating is uneven, and because the coating itself is low in strength, not wear-resistant, it is easily damaged by external forces; the fourth is that the sound absorptio...
