Abstract

The invention discloses a self-healing type non-self-adhesive modified asphalt waterproof coiled material which is characterized by consisting of a modified asphalt coating material, a tire body and an isolation material, wherein the modified asphalt coating material consists of the following components in percentage by mass: 40-50% of petroleum asphalt, 3-6% of machine oil, 8-12% of high polymer material, 15-20% of expanding material, 0.2-0.6% of active agent, 10-20% of cement and 5-15% of filler. During preparation, the coating material is uniformly mixed and then is coated on the tire body, and then the tire body is covered with the isolation material to obtain the self-healing type non-self-adhesive modified asphalt waterproof coiled material. By virtue of tests performed according to relevant national or industrial test methods, the waterproof coiled material disclosed by the invention has good mechanical properties and excellent self-healing performance.

Description

technical field [0001] The invention relates to a waterproof coiled material for construction, in particular to a self-healing non-self-adhesive modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Asphalt is widely used in building waterproofing materials due to its excellent hydrophobicity. In the 1920s, asphalt waterproof felt was available in Europe. In the 1930s, developed countries in Europe and the United States modified asphalt with plastic or rubber to make waterproof membranes, and achieved good application results. Since the 1990s, modified asphalt waterproofing membranes have developed rapidly in China. According to industry statistics in 2012, modified asphalt waterproofing membranes account for half of the waterproofing materials, which shows the importance of its waterproof status. [0003] In the mid-1990s, real estate developed rapidly in China, and there were many high-rise buildings. In the past, wate...
