Abstract

The present invention relates to a polymer-based film waterproofing agent mixed with cement which is coated on a structure requiring waterproofing and water leakage prevention so as to show excellent chemical resistance, weather resistance, crack resistance and impact resistance and high tensile strength in addition to waterproofness by preventing penetration of water into the structure, and a preparation method thereof. The polymer-based film waterproofing agent mixed with cement of the present invention comprises: 65-75 wt% of an acrylic emulsion; 12-20 wt% of micro-cement; 10-18 wt% of quicklime; 0.02-0.2 wt% of a superplasticizer; 0.02-0.2 wt% of an antifoaming agent; and 0.02-0.2 wt% of an expansion agent. The preparation method comprises: the first step of preparing 65-75 wt% of an acrylic emulsion in a liquid state in a first circular container; the second step of preparing 12-20 wt% of micro-cement in a powder state, 10-18 wt% of quicklime, 0.02-0.2 wt% of a superplasticizer, 0.02-0.2 wt% of an antifoaming agent, and 0.02-0.2 wt% of an expansion agent in a second circular container; and the third step of pouring the contents prepared in the second circular container into the first circular container to dilute the same with an electric mixer.

Embodiment

[0044] Embodiments for achieving the object of the present invention are described below.

[0045] First, a commercially available liquid-state acrylic emulsion is prepared.

[0046] In addition, small packages of superfine cement (MS8000) and quicklime that do not react with each other are prepared in advance, and the above-mentioned additives (superplasticizer, defoamer, expansion agent) are also packaged in small packages at the same time, to be prepared.

[0047] Measure the weight of each of the above materials, prepare 70% by weight of acrylic emulsion, 16% by weight of superfine cement, 13.8% by weight of quicklime, 0.06% by weight of superplasticizer, 0.1% by weight of defoamer, and 0.04% by weight of expansion agent. The above-mentioned acrylic emulsion in liquid state is poured into the first drum, and other ultra-fine cement, quicklime, superplasticizer, defoamer and expansion agent in powder state are poured into the second drum, and the lid is closed for storage. ...
