Abstract
The invention belongs to the field of materials, and particularly relates to high polymer modified asphalt, a waterproof coiled material, and preparation methods and applications thereof. The petroleum asphalt and the natural rock asphalt are selected and used in a compounding way, and the blended SBS is used as the modifier, so that the prepared modified asphalt has the characteristics of high tensile strength and high elongation, and strong adaptability to base shrinkage, deformation and cracking. The waterproof coiled material prepared by compounding the modified asphalt with the glass fiber reinforced polyester tire, the polyester composite polyester tire and the steel wire reinforced polyester tire has good anti-crushing property, anti-rolling property and thermal dimensional stability, has strong anti-permanent deformation capability in the high-temperature heavy-load operation process, is particularly suitable for bridge deck engineering of related projects of railway construction, and is simple and rapid in construction.
Description
Technical Field
The invention belongs to the field of materials, and particularly relates to high polymer modified asphalt, a waterproof coiled material, and preparation methods and applications thereof.
Background
As one of the national key project construction waterproof materials, the modified asphalt waterproof coiled material special for the railway bridges and culverts plays an important role in railway waterproof construction.
At present, most of waterproof coiled materials used in the market are modified asphalt waterproof coiled materials special for common railway bridges and culverts, and on one hand, the material strength cannot meet the repeated rolling force in the high-temperature heavy-load operation process of railway bridge floors; on the other hand, the tear resistance of the material is poor, and the crushing force of the material generated by the environment or other factors cannot be resisted; in the third aspect, the material produced by the polyester tire has poor dimensional stability, and the short side is easy to shrink after hot melting construction; in the fourth aspect, the durability of the material is poor, and the waterproof service life requirement of railway construction cannot be met. Therefore, it is urgently needed to develop a waterproof roll material which can ensure that the waterproof roll material has certain crushing resistance and crushing resistance, can ensure that the material has excellent aging resistance, has good dimensional stability, and can ensure that short-edge shrinkage does not occur along with the lapse of time or the change of environmental temperature difference after the hot melting construction of the material is completed.
Disclosure of Invention
The invention aims to provide a high polymer modified asphalt, a waterproof coiled material, a preparation method and application thereof.
In order to achieve the above object, a first aspect of the present invention provides a polymer-modified asphalt comprising: 40-50 parts of petroleum asphalt, 10-15 parts of natural rock asphalt, 18-20 parts of blended SBS, 5-8 parts of polyethylene wax, 3-5 parts of reinforcing agent, 3-5 parts of viscosity reducer, 3-5 parts of anti-aging agent and 5-15 parts of inorganic filler;
