The present invention relates to a self-adhesive rubberized asphalt waterproof sheet using a quick-drying rubberized asphalt membrane material including a silane compound and a biaxial-stretching high density poly ethylene film, and a composite waterproofing method using the same. Specifically, according to the self-adhesive rubberized asphalt waterproof sheet, the construction is enabled even though a concrete surface is in wet condition, and the effect of volatilizing a coated surface and an internal solvent at the time of coating and the compatibility between rubberized asphalt and a self-adhesive rubberized asphalt waterproof sheet are increased so as to improve the stability and properties of products. In addition, the self-adhesive rubberized asphalt waterproof sheet uses the acryl silane primer and the quick-drying rubberized asphalt membrane material for improving the adhesive strength in a wet surface, providing a more convenient construction method rather than existing construction methods. The self-adhesive rubberized asphalt waterproof sheet has a high density poly ethylene film which is superior in durability, water resistance, chemical resistance and cold resistance at the upper portion and an asphalt compound at the lower portion so as to increase the adhesive performance with respect to the quick-drying rubberized asphalt membrane material and the watertightness between sheets with respect to each other. In the self-adhesive rubberized asphalt waterproof sheet, a bi-directionally intersecting biaxial-stretching high density poly ethylene (HDPE) film is compressed at the upper portion, rubberized asphalt of which thermal stability at high temperature and the adhesive force at low temperature are improved is provided as a main material in the center portion, and the lower portion is finished by a silicon release paper, such that work efficiency and the adhesion force at low temperature and a vertical wall are maintained to be the maximum. |
