Embodiment 1

[0021] Embodiment 1: the composition of the present invention is respectively 35-45% 90# base asphalt by mass fraction, 35-50% Butonite (BRA), 8-12% SBS (Chinese is: styrene-butadiene Diene-styrene block copolymer), 3-5% naphthenic oil, 2-5% polypropylene (PP), 0-10% talc.

[0022] Preparation method of the present invention:

[0023] Take 43% of 90# matrix asphalt and heat it to 135°C, mix in 37% of the treated Butonite (BRA), and stir at 300r / min for 0.5h, so that the Butonite (BRA) is evenly dispersed in the matrix asphalt, That is to get Buton rock (BRA) modified asphalt, then raise the temperature of Buton rock (BRA) modified asphalt to 185°C, add 10% polymer SBS, continue to stir for 2 hours, so that polymer SBS is uniformly dispersed in the modified Then add 5% naphthenic oil, 3% polypropylene (PP), and 2% talcum powder to the asphalt and continue to stir for 5 hours to prepare an elastomer-modified asphalt waterproof membrane coating material.

Embodiment 2

[0024] Embodiment 2: The difference between this example and Example 1 is: the preparation method of this example is as follows:

[0025] Take 40% of the 90# base asphalt and heat it to 130°C, mix in 47% of the treated Buton rock (BRA), and stir at 300r / min for 0.5h, so that the Buton rock (BRA) is evenly dispersed in the base asphalt, That is to get Buton rock (BRA) modified asphalt, then raise the temperature of Buton rock (BRA) modified asphalt to 200°C, add 8% polymer SBS, continue to stir for 2 hours, so that polymer SBS is uniformly dispersed in the modified Then add 3% naphthenic oil and 2% polypropylene (PP) to the asphalt and continue to stir for 5 hours to prepare an elastomer-modified bitumen waterproof membrane coating material.

Embodiment 3

[0026] Embodiment 3: The difference between this example and Example 1 is: the preparation method of this example is as follows:

[0027] Take 41% of 90# matrix asphalt and heat it to 140°C, mix in 40% of the treated Butonite (BRA), and stir at 300r / min for 0.5h, so that the Butonite (BRA) is evenly dispersed in the matrix asphalt, That is to get Buton rock (BRA) modified asphalt, then raise the temperature of Buton rock (BRA) modified asphalt to 190°C, add 12% polymer SBS, continue stirring for 2 hours, so that polymer SBS is uniformly dispersed in the modified Then add 5% naphthenic oil and 2% polypropylene (PP) to the asphalt and continue to stir for 5 hours to prepare an elastomer-modified bitumen waterproof membrane coating material.

Abstract

The invention provides a Buton rock-modified asphalt waterproof rolling material coating material and a preparation method thereof, and belongs to the technical field of waterproof materials. The coating material is prepared from, by mass, 35%-45% of 90#matrix asphalt, 35%-50% of Buton rock, 8%-12% of SBS, 3%-5% of naphthenic oil, 2%-5% of polypropylene and 0%-10% of talcum powder. According to the Buton rock-modified asphalt waterproof rolling material coating material and the preparation method thereof, the Buton rock is treated and then doped into the matrix asphalt to prepare Buton rock-modified asphalt, and then the SBS modifier is added to prepare SBS-Buton rock composited modified asphalt; compared with the process that the asphalt is modified by the SBS singly, by adding the Buton rock, the production cost can be reduced, the high temperature resistance and the separation property of the modified asphalt are improved, and not only is the effect of replacing part of the SBS modifier achieved, but also the properties of the modified asphalt can be improved; due to the fact that the Buton rock contains 70% or above of carbonate, part or even all fillers such as the talcum powder can be replaced by doping the Buton rock.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and in particular relates to a Buton rock modified asphalt waterproof membrane coating material and a preparation method thereof. Background technique [0002] At present, my country's building waterproof material industry is developing rapidly, and the product structure has also been greatly improved. As a major category of asphalt-based waterproof membranes, modified bitumen waterproof membranes have rapidly increased their share in the waterproof material market. At the same time, with the increase of permanent buildings and the commercialization of residential buildings, people have higher and higher requirements for building waterproofing, and the accelerated promotion of high-grade waterproof materials has become inevitable. However, with the popularization of modified asphalt waterproofing membranes, many problems follow. Due to the high cost of polymer modified bitumen water...
