The present invention relates to a waterproof sheet using a water-soluble acryl polymer and to a method for producing the same. More specifically, a waterproof sheet is provided, wherein a top coating layer of unfading acryl urethane is formed by bonding a glass fiber mesh fabric and a synthetic fiber non-woven fabric which have excellent durability with a waterproof layer of a water-soluble acryl polymer waterproof agent and a silicic acid layer of a silica dioxide liquid. Accordingly, even though the waterproof sheet is used for a long time, deterioration can be prevented and waterproof functions can be maintained for a long time. A glass fiber mesh fabric, a synthetic fiber non-woven fabric, and a glass fiber mesh fabric are sequentially prepared on the top of a paper sheet having releasing properties. An EVA double-faced tape is prepared on the top and bottom of the glass fiber mesh fabric on the top thereof, so that a bank unit is formed. The waterproof layer of the water-soluble acryl polymer waterproof agent and the silicic acid layer of the silica dioxide liquid are prepared, are compressed by means of a roller, and are dried through a drying furnace, so that a waterproof sheet is provided, a top coating layer of non-fading acryl urethane is formed on the top of the silicic acid layer. By means of the glass fiber mesh fabric, durability is improved, and deterioration can is prevented despite long-term use, so that waterproof functions can be maintained for a long time. At the same time, the price as a waterproof sheet is cheap, properties are very excellent, and perfect waterproofing effects can be obtained. |
