Description
Technical Field
The invention belongs to the technical field of waterproof building materials, and particularly relates to a high-performance high-yield modified asphalt waterproof coiled material and a preparation method thereof.
Background
The heat resistance of the modified asphalt is the capability of the asphalt coiled material test piece vertically hanging at a specified temperature, and the coating layer does not slide more than 2mm compared with the matrix. There is a certain correlation between the softening point and the heat resistance, and the technical personnel need to increase the softening point heat resistance of the modified asphalt by 10-20 ℃ to ensure enough heat resistance. In this case, the high-temperature performance modifier is mostly a polymer compound such as rubber and plastic or polymer wax.
The polymer compound has an important parameter, i.e., melt index or melt flow rate, and when it is used as an asphalt modifier, the melt index of the polymer compound has a direct influence on the fluidity of the modified asphalt. A high molecular weight substance having a low melt index means poor flowability under the same conditions. When the temperature of the modified asphalt is lowered to the vicinity of the softening point of the modifier, the modifier molecules substantially lose fluidity or have poor fluidity, thereby resulting in an increase in the consistency of the modified asphalt, making blanking and coating difficult. At this time, if the temperature of the modified asphalt is simply raised to obtain proper fluidity, the high temperature of the modified asphalt may cause a series of quality and cost problems such as high-temperature aging of the modifier, film burning of the coil, difficulty in cooling, increase in energy consumption and the like. Therefore, it is urgently needed to develop a modified asphalt waterproof coiled material which can solve the above disadvantages and has the advantages of productivity and cost.
