[0039] The preparation method of modified asphalt of the present invention, comprises the steps:

[0040] Add the petroleum asphalt into the mixing tank, stir and heat up to 150°C;

[0041] Adding the nano-silica and the nano-zeolite into the stirring tank, stirring at 150-160° C. for 1.5-2.5 hours to obtain a mixture;

[0042] The mixture is sheared and ground for 1 to 1.5 hours through a colloid mill at a temperature of 150-160°C and a rotational speed of 2900-3600r / min.

[0043] Preferably, the step of adding the petroleum asphalt into the stirring tank also includes adding a softener and a tackifier to the stirring tank; adding the nano silicon dioxide and the nano zeolite to the stirring tank It also includes adding a thermoplastic elastomer into the mixing tank.

[0044] The addition of the thermoplastic elastomer, softener and tackifier can improve the comprehensive performance of the modified asphalt.

[0045]The present invention also provides a nano-reactive adhes...

Abstract

The invention discloses modified asphalt, a method for preparing the modified asphalt and a nanometer reaction adhesive waterproof roll. The modified asphalt comprises petroleum asphalt and nano particles, wherein the nano particles include nano-silica and nanosized zeolite, and the weight ratio of nano particles to petroleum asphalt is (36-44):100. By adding nano-silica and nanosized zeolite to petroleum asphalt, the high temperature resistance of petroleum asphalt is improved.

Description

technical field [0001] The invention relates to the technical field of asphalt modification, in particular to a modified asphalt, a preparation method thereof, and a nano-reactive adhesive waterproof membrane using the modified asphalt. Background technique [0002] At present, most asphalt is often exposed to sunlight for a long time as a waterproof material. Its waterproof layer often slides, drips, and flows due to sunlight, so that its waterproof layer is damaged, damaged or even invalid, and generally has the defect of poor high temperature resistance. Contents of the invention [0003] The main purpose of the present invention is to provide a modified bitumen, aiming at improving the high temperature resistance of the bitumen. [0004] In order to achieve the above object, the modified asphalt proposed by the present invention includes petroleum asphalt and nanoparticles, and the nanoparticles include nano-silicon dioxide and nano-zeolite, and the weight ratio of th...
