Description
The application is a divisional application of a patent application with the application date of 2016, 4 and 20, and the application number of 201610250403.0, and the name of the invention is 'modified asphalt for waterproof coiled materials and a preparation method thereof'.
Technical Field
The invention relates to modified asphalt and a preparation method thereof, in particular to modified asphalt for waterproof coiled materials and a preparation method thereof.
Background
Since the middle of the 80 s of the 20 th century, with the rapid development of infrastructure in China, the demand of the infrastructure on modified asphalt waterproof materials is larger and larger, and the requirements on waterproof coiled materials are higher and higher. Among them, polymer modified asphalt has become an effective way to improve the low-temperature flexibility of asphalt, but its price is high and its cost is high. Therefore, it is necessary to add a softening agent during the preparation of the modified asphalt to improve the low-temperature flexibility of the modified asphalt.
At present, the modified asphalt softener commonly used in China is petroleum hydrocarbon, such as three-line oil, recovered waste engine oil, two-line oil and the like. In recent years, the external and internal quality of finished products in the modified asphalt waterproof coiled materials meet the national standards during factory detection, but after a period of time, the coiled materials have oil separation phenomenon, such as yellowing or rust spots on the surfaces of the coiled materials, so that the low-temperature flexibility of the coiled materials is unqualified, and the service life of the products is reduced; meanwhile, the preparation is complex and the production cost is high. Therefore, the development of the modified asphalt waterproof coiled material with high-stability low-temperature flexibility, good aging resistance and longer service life has great significance for improving the waterproof coiled material.
Disclosure of Invention
The invention aims to solve the technical problem of providing modified asphalt for waterproof coiled materials, which has high-stability low-temperature flexibility, good aging resistance and longer service life, and a preparation method thereof.
The technical scheme adopted for solving the technical problems is that the modified asphalt for the waterproof coiled material comprises the following components in parts by weight:
wherein the softening agent is polyethylene glycol, glycerol, pentaerythritol oleate or pentaerythritol acrylate.
Further, the modified asphalt for the waterproof coiled material comprises the following components in parts by weight:
further, the modified asphalt for the waterproof coiled material comprises the following components in parts by weight:
further, the petroleum asphalt is No. 70 or No. 90 base asphalt.
Further, the stabilizer is a polymeric monoolefin.
Further, the polymer monoolefin is polypropylene.
Further, the filler is talcum powder.
According to the technical scheme for further solving the technical problems, the preparation method of the modified asphalt for the waterproof coiled material comprises the steps of stirring the petroleum asphalt and the softening agent, heating to 160-170 ℃, adding the SBS modifier and the stabilizer, mixing for 2-3 hours at the rotating speed of 1000-2000 rpm/min, adding the filler, and stirring for 50-70 minutes.
The modified asphalt for the waterproof coiled material prepared by the novel softener is greatly improved in flexibility stability and aging resistance at low storage temperature compared with the modified asphalt prepared by the petroleum hydrocarbon softener, and has the advantages of simple preparation steps, low production investment and remarkable economic and social benefits.
The action mechanism of the novel softener is as follows:
the network structure of SBS modified asphalt is a process of polymer adsorption and swelling for phase inversion. Novel softener and SBS are fine in the modification process and dissolve mutually and form intertwine and reach network structure, and effectual improvement its stability avoids producing and is only the individual molecule dispersion of simple high temperature, then mixes loose structure, meets the heat back a little, leads to intensity to reduce, and the adhesion worsens, and aromatic oil from it is appeared, influences the inherent quality and the appearance quality of coiled material.
Compared with the prior art, the invention has the following outstanding characteristics:
1. the low-temperature flexibility of the waterproof coiled material is slowly attenuated, and the service life of the product is ensured.
2. The appearance of the coiled material does not have the phenomena of yellowing and rusty spot.
3. In the production process of the coiled material, less waste oil smoke is generated, and the coiled material is more environment-friendly.
Experiments prove that the original low-temperature limit of the waterproof coiled material prepared by the modified asphalt is-29.0 ℃, the low-temperature limit after 30 days of use can reach-28.4 ℃, and the low-temperature limit of thermal aging can reach-26.5 ℃; compared with the modified asphalt waterproof coiled material prepared by replacing the same scheme with the common petroleum hydrocarbon softener, the original low-temperature limit of the modified asphalt waterproof coiled material is-29.0 ℃, the low-temperature limit after 30 days of use can reach-25.0 ℃, and the low-temperature limit of thermal aging can reach-17.4 ℃, so that the improvement on the aspect of low-temperature flexible storage stability is remarkable.
