Description
Technical field
The invention belongs to highway pavement patching material field, and in particular to a kind of strong road casting glue of corrosion resistance and its
Preparation method.
Background technology
Crack is the principal mode of road surface early damage, and water penetration causes roadbed into sub-surface structure in order to prevent
Irreversible damage, it is frequently with one of measure remedied using sealing adhesive for crack, that is, casting glue fill up.Rationally utilize
Sealing adhesive for crack can prevent pavement crack from further deteriorating, and extend the service life on road surface.In different types of crack repairing
In packing material, it is the most common type patching material to vulcanize pitch sealing adhesive for crack, its construction is simple, setting time are short,
The usual cementation of fissures is after twenty minutes solidifiable open to traffic, and cheap, cheap compared to cold-penetration sealing more than 50%.
It is to be noted, however, that water in nature, air circulation all can have certain corruption to exposure material therein
Erosion, road gap-grouting glue are no exception.Bituminous paving exposes in atmosphere, and vehicle is by various corrosive substances (such as kerosene, vapour
Oil) it is covered in by wheel on bituminous paving, crack material for repairing is also unable to escape misfortune.The corrosion of empty gas and water, corrosive substance
The repair efficiency of meeting fracture patching material is had a greatly reduced quality, and therefore, road casting glue needs good corrosion resistance.
The content of the invention
For the shortcoming of existing road casting glue, it is an object of the invention to provide a kind of strong road of corrosion resistance
Casting glue and preparation method thereof.
The present invention provides a kind of strong road casting glue of corrosion resistance, it is made of the raw material of following parts by weight：
Preferably, the pitch selects No. 90 matrix pitches.
Preferably, the discarded aramid fiber passes through pulverization process.
Preferably, the particle diameter of the silicon powder is less than 200 mesh；The particle diameter of the rubber powder and carbon dust is in 20-40 mesh.
The preparation method of road casting glue according to the present invention, comprises the following steps：
(1) match somebody with somebody according to parts by weight and take each component；
(2) by asphalt heating to 160-170 DEG C, and it is stirred continuously, successively adds SBS modifier, stirring reaction thereto
40-45 minutes；
(3) 180-190 DEG C is warming up to, polystyrene is added into system, is stirred 30-40 minutes；
(4) 190-200 DEG C is increased the temperature to, uniformly mixed silicon powder, rubber powder and carbon dust are added in system, stirring is anti-
Answer 50-60 minutes；
(5) 180-190 DEG C is cooled to, discarded aramid fiber is added into system, stirs 60-70 minutes, waits to cool to
120-130 DEG C can pack, and road casting glue is prepared.
Preferably, speed of agitator is 2000rpm described in step (2), step (3), step (4) and step (5).
Preferably, the casting glue is repaiied for the sealing of common road, highway, airfield runway crack and seam
It is multiple.
Elaboration to the present invention and its advantage：Road gap-grouting glue prepared by the present invention has good corrosion resistance
Can, it can be weakened significantly by corrosion damage degrees such as empty gas and water, corrosive substances, the use longevity of casting glue is filled in crack
Life extends, it is necessary to safeguard that the cycle of reparation also increases；Wherein, pitch is modified with SBS modifier, enhances the glue of pitch
Stickiness energy, so as to preferably be binded with crack；Polystyrene has preferable acid-alkali-corrosive-resisting performance, and can be with aramid fiber
Fiber interaction, forms elastic anti-corrosion erosion protective layer, avoids the casting glue in filled crack from being corroded easily, especially right
Water, air and faintly acid corrosive deposit are by preferable defence capability；The main composition of silicon powder is silica, can be resisted usually
Soda acid corrode, the present invention in silicon powder particle diameter be far smaller than rubber powder or carbon granules, silicon is micro- when three is uniformly mixed
Powder can be adsorbed in the surface of rubber and carbon granules, and adding in the system containing polyethylene makes silicon powder tight bond and bulky grain table
Face, is then further fixed by aramid fiber, rubber powder or carbon grain surface is protected by silicon powder, so as to reduce pair
Its directly etching, can effectively strengthen the service life of casting glue；Using discarded aramid fiber from superseded in the present invention
The materials such as rope, gloves, protective garment, realize and the effective of waste are recycled.
