Abstract

The invention relates to elastic putty for outer walls. The elastic putty is composed of the following components proportionally in percentage by mass relative to the total mass: 40-60% of elastic emulsion, 0.1-0.3% of dispersing agent, 0.2-1% of propylene glycol, 0.1-0.3% of cellulose, 0.1-0.3% of defoaming agent, 20-30% of calcium carbonate, 3-3.5% of wollastonite in powder, 0.1-0.3% of preservative, 0.3-0.7% of thickener and the balance of water. The product of the elastic putty disclosed by the invention has stronger elasticity and superstrong binding power at normal temperature, has a superior waterproof performance, is a high-quality embedded material for the outer walls of buildings, and can be used for covering craquelures of wall surfaces so as to prevent the wall surfaces from looseness or further cracking, and protecting cavity reinforcing steel bars from oxidation.

Description

technical field [0001] The invention relates to a building coating, in particular to an elastic putty for exterior walls. Background technique [0002] On the walls that have been painted with primer or topcoat, cracks and unevenness will occur due to various reasons, which will not only damage the appearance of the wall, but also cause water seepage on the wall, greatly reducing the waterproof performance. If the remedial measures are taken, the wall will be loose and further cracked, causing irreparable losses. Contents of the invention [0003] In order to solve the above problems, the present invention provides an elastic putty for external walls with good elasticity, good cohesive force and excellent waterproof performance. [0004] The technical scheme of the present invention is: be made up of elastic emulsion, dispersant, propylene glycol, cellulose, antifoaming agent, calcium carbonate, wollastonite powder, preservative, thickener and water, each composition acco...
