The invention belongs to the technical field of
cement-based waterproof materials and particularly relates to a
cement-based waterproof material and a preparation technology thereof. The
cement-basedwaterproof material comprises, by weight, 15-20 parts of
plant straw, 45-50 parts of cement, 25-30 parts of
quartz sand, 10-15 parts of
inorganic filler, 35-40 parts of polyacrylate solution, 16-20 parts of
phospholipid molecule solution, 0.5-1 part of tetramethyl
thiuram disulfide, and 1-2 parts of polyether modified organosilicone. According to the preparation technology of the cement-based waterproof material, the softened
plant straw is twisted into a thick twist shape through a twisting and segmenting device, besides, segmentation treatment is conducted, and then small twist-shaped plantstalk segments are dispersed in
cement mortar; and in this way, the tensile strength of the cement base can be improved, and the cement-based waterproof material is prevented from
cracking during use.At the same time, the thick
plant straw is of a fluffy porous structure, then the thick plant straw can play a role in
water retention similar to ceramsite, the water inside the plant straw can be released in the later stage of the
cement mortar, so that the cement can be fully hydrated, and then the strength of the cement-based waterproof material is improved.
