Abstract

The invention discloses an anti-cracking crack filling composition and a preparation method thereof and relates to the technical field of wall materials. The anti-cracking crack filling composition isprepared from the following raw materials: 70-90 parts of styrene-butadiene latex, 70-90 parts of cement, 30-45 parts of molding agent, 20-30 parts of silicon micro powder, 15-25 parts of calcium oxide concrete expansion agent, 10-15 parts of polyacrylamide, 10-15 parts of vinyl acetate and ethylene copolymerized emulsion powder, 10-15 parts of filler, 5-10 parts of modified penicillin fungi residue filtrate, 5-10 parts of litsea cubeba oil, 2-6 parts of sodium citrate, 2-6 parts of sodium lauryl sulfate, 1-5 parts of dispersant and 30-60 parts of water. The anti-cracking crack filling composition has excellent permeability and adhesion, and is rapid in molding speed.

Description

technical field [0001] The invention relates to the technical field of wall materials, in particular to an anti-cracking joint filling composition and a preparation method thereof. Background technique [0002] In the current construction projects, the concrete floor or wall still needs to be leveled after it is solidified. When the ground and wall are further repaired and leveled, it is a necessary link to repair the pinholes and small cavities generated on the ground. Workers are required to fill the gaps on the ground and walls one by one, but the existing gap filling materials are not stable enough, the strength is not high, and the adhesion is not good enough to meet the repair requirements, resulting in secondary repairs and increased Construction difficulty and construction volume. Contents of the invention [0003] The purpose of the present invention is to provide an anti-cracking joint filling composition and its preparation method, which have excellent permeabi...
