Abstract

The invention provides a high-temperature resistant self-adhesive polymer modified asphalt waterproofing membrane and a preparation method thereof. The high-temperature resistant self-adhesive polymer modified asphalt waterproofing membrane comprises the following raw materials by weight: 50 to 60 parts of No. 100 asphalt, 5 to 10 parts of softening oil, 20 to 30 parts of pulverization reclaimed rubber powder, 6 to 12 parts of rubber powder modifier, 20 to 30 parts of coarse whiting powder, and 2 to 3 parts of pure polypropylene. The preparation method comprises the following steps: taking the No. 100 asphalt and softening oil according to the parts by weight; stirring and mixing the No. 100 asphalt and the softening oil; adding the pure polypropylene when the temperature reaches 190 to 200 DEG C; adding the pulverization reclaimed rubber powder when the pure polypropylene is completely melted; keeping stirring for 120 min when the temperature reaches 200 minus or plus 5 DEG C; adding the rubber powder modifier when the temperature falls to 170 minus or plus 5 DEG C; mixing and stirring uniformly when the coarse whiting powder is added, so as to obtain a finished mixture; and making the finished mixture into modified asphalt waterproofing membranes according to the manufacture procedure. As asphalt is modified to bear temperature higher than 120 DEG C, the invention has the advantages that no sliding phenomenon is generated under a high temperature; the viscosity is higher; and the suitability to construction environments is high.

Description

technical field [0001] The invention relates to a waterproof coiled material and a preparation method thereof. In particular, it relates to a high-temperature-resistant self-adhesive polymer modified asphalt waterproof coiled material made by using modifier modified asphalt mixture and a preparation method thereof. Background technique [0002] Self-adhesive waterproof membrane is a new type of waterproof material with great development prospects. Its application in our country began in the early 1990s. Its standards have gone through self-adhesive rubber asphalt waterproofing membrane (JC 840-1999), self-adhesive polymer modified asphalt polyester tire waterproofing membrane (JC 898- 2002) industry standard to the later waterproof membrane with self-adhesive layer (GB / T 23260-2009), pre-paved / wet-laid waterproof membrane (GB / T 23457-2009), self-adhesive polymer modified bitumen waterproof membrane Material (GB 23441-2009) and other national standards, the variety has grad...
