Abstract

The invention discloses a modified asphalt adhesive and a preparation method thereof. The preparation method comprises the following steps: pumping fused asphalt in a stirring kettle; starting a stirring paddle, wherein, the stirring speed is 60-200 revolutions/min, and the material temperature is 120-150 DEG C; stirring for 10-30min; adding styrene-butadiene block copolymer (SBS) and styrene butadiene rubber (SBR) and continuously stirring; heating to 160-180 DEG C; stirring for 1-2h; keeping the stirring temperature and the stirring speed; adding tackifier; continuously stirring for 30-60min; adding rubber powder and filler in sequence; continuously stirring for 30-60min; and grinding by a colloid mill to obtain the modified asphalt adhesive with good performance.

Description

technical field [0001] The invention relates to the field of waterproof materials, in particular to a modified asphalt adhesive with good adhesive performance, excellent high-temperature resistance and low-temperature resistance. Background technique [0002] With the vigorous development of national large-scale infrastructure construction and municipal engineering, waterproof engineering has become the top priority of these projects, and waterproof issues have attracted much attention. A variety of new waterproof materials emerge in endlessly. The performance of waterproof materials directly affects the success or failure of waterproof projects, and then affects the quality of use of the entire project. Therefore, users are very cautious in choosing waterproof materials during waterproof construction. With the higher and higher requirements for the quality of waterproofing projects, at the same time, the development potential of the field of waterproofing materials has also...
