Abstract

The invention discloses a self-adhesion modified asphalt waterproofing coil coating material, a preparation method thereof and a passive special self-adhesion asphalt waterproofing coil for buildings.The raw materials for preparing the self-adhesion modified asphalt waterproofing coil coating material include the following components: mixed asphalt, polyethylene wax, a stabilizer, a linear SBS modifier, a powder SBR modifier, tackifying resin and inorganic filler, wherein the mixed asphalt is a mixture of petroleum asphalt and softening oil, and the stabilizer is a mixture of polyphosphoric acid and a phosphotriester. The self-adhesion asphalt waterproofing coil has a longitudinal-transverse tensile value of >= 1000 N and elongation of >= 2%, and the modified asphalt is special-made modified asphalt, and is characterized by good compactness and high temperature resistance; and compared with ordinary self-adhesion modified asphalt, the modified asphalt is delicate, and has no bubbles and resistance to a high temperature of 100 DEG C.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and more specifically relates to a self-adhesive modified asphalt waterproof membrane coating material and a preparation method thereof, and a self-adhesive asphalt waterproof membrane specially used for passive buildings. Background technique [0002] The current standards for waterproofing membranes are far from those of passive houses, mainly due to the differences in the materials themselves and the essential differences in the structure of the waterproofing system. [0003] With the rapid development of passive house projects, more and more well-known domestic waterproof companies are eager to enter this field. However, as a new type of building, the waterproof material index in passive house buildings must be higher than that of existing products in order to meet higher waterproof effects and durability. [0004] Currently, conventional modified asphalt waterproofing membranes...
