Abstract
The invention provides an asphalt binder for producing a pre-paved and wet-paved waterproof roll as well as a preparation method and an application of the asphalt binder. The asphalt binder comprises the following components in percentage by mass: 65-75% of asphalt, 20-30% of rubber oil and 5-10% of SBS. Compared with asphalt, the modified asphalt binder provided by the invention has the advantages that the ductility, softening point and penetration degree of the asphalt binder are remarkably improved, while the low-temperature flexibility, high-temperature resistance and stripping property (between glue and glue and between glue and an aluminum plate) of a corresponding waterproof roll product are also remarkably improved, and particularly, the low-temperature flexibility is more remarkable.
Description
Technical field
The invention belongs to modified asphalt technology field, being specifically related to a kind of asphalt size, preparation method and its usage for the production of overlaying wet paving waterproof roll.
Background technology
Pitch is a kind of product of Crude Oil Processing, at normal temperatures the thick liquid of black or chocolate or solid, and it is the organic material as a form of gel of a kind of brownish black, comprises rock asphalt, petroleum pitch, shale tar pitch and coal-tar pitch etc. four kinds.The main component of pitch is bituminous matter and resin, the compound of next oxygen, sulphur and the chlorine that have high boiling point mineral oil a small amount of.Pitch has gloss semi-solid state, and during low temperature, matter is crisp, and cohesiveness, water resistance and antiseptic property are fine.
Overlay/wet paving waterproof roll, be proposed by Chinese architecture material federation, specifically see GB/T23457-2009 standard.Pitch, be widely used in road, waterproofing work and anticorrosion on.But because pitch is not fine in performances such as high temperature resistant, resistance to flow, low temperature flexibility and weathering resistancies, make on effect, there is a lot of problem, such as waterproof roll low temperature flexibility, high temperature resistant and force of cohesion is not ideal enough, coiled material is very crisp at low temperatures to make waterproof roll factory coiled material, easily broken, there is trickling in temperature height, drippage is difficult to dyestripping, and force of cohesion is low can not provide the power with structure basal plane, easily departs from basal plane.
Modifying asphalt sizing material is admixture rubber, resin, high molecular polymer, levigate rubber powder or other fillers etc. are outer mixes crowded (properties-correcting agent) or takes, to measures such as pitch mild oxidation processing, to make pitch or asphaltic binder.In recent years, along with the widespread use of properties-correcting agent in pitch, be combined material modified with traditional asphalt, then add suitable softening oil, bitumen ductility and low temperature flexibility can be significantly improved, promote the cohesiveness of waterproof roll, resistance to low temperature and weathering resistance.
Summary of the invention
Based on this, the object of the present invention is to provide a kind of asphalt size for the production of overlaying wet paving waterproof roll, this modifying asphalt is used for overlay/wet paving waterproof roll major ingredient, the low temperature flexibility of waterproof roll, high temperature resistant and force of cohesion can be improved, there is excellent water resistance.
