Description
Technical field
The invention belongs to highway pavement patching material field, and in particular to a kind of strong asphalt sealant of non-deformability 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%.
Road has the debris such as many stones, chip during operation and falls into road, when vehicle passes through these debris by
Vehicle influences to squeeze into crack, and the fissured structure filled up can be destroyed, it is therefore desirable to which sealing adhesive for crack has good resist
Foreign matter embeddability, i.e. non-deformability, to prevent foreign matter quilts under the action of wheel such as the chip of sandstone on road surface, nature
Destroy in press-in joint sealing material and fill up effect,
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 drip of non-deformability
Blue or green fluid sealant and preparation method thereof.
The present invention provides a kind of strong asphalt sealant of non-deformability, it is made of the raw material of following parts by weight：
Preferably, the pitch selects No. 90 matrix pitches.
Preferably, the metal dust is the one or more in cobalt, copper, iron, manganese, lead, nickel.
Preferably, the glass fibre selects continuous glass fibre；Content of triglyceride in the recycled wood materials
More than 70%.
The preparation method of asphalt sealant 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 thereto and discard edible
Grease, stirring reaction 40-45 minutes；
(3) 200-210 DEG C is increased the temperature to, glass fibre and rubber powder, stirring reaction 50-60 are successively added into system
Minute；
(4) maintain temperature to add polyurethane into system at 200-210 DEG C, stir 60-70 minutes；
(5) 130-140 DEG C is cooled to, adds metal dust, is stirred 20-30 minutes, cooling to 120-130 DEG C can wrap
Dress, is prepared asphalt sealant.
Preferably, the speed of agitator described in step (2), step (3) and step (4) is 2000rpm；In step (5)
The speed of agitator is 200rpm.
Preferably, the fluid sealant 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：Asphalt sealant prepared by the present invention has excellent resistance to deformation energy
Power, is not easy to be extruded or occurred substantial amounts of deformation under external force, can effectively prevent sandstone on road surface, nature
The foreign matters such as chip are pressed under the action of wheel in joint sealing material fills up effect so as to destroy crack；Wherein, with SBS modifier
During modified pitch matrix, recycled wood materials are added, because its main component is triglycerides, can effectively reduce pitch and its
Bonding resistance between remaining fluid sealant component, and enhance the toughness of fluid sealant；The glass fibers added in fluid sealant raw material
Dimension can high temperature resistant, while be used as linear fibre, attachment force and intensity inside fluid sealant can be strengthened, make it in hot conditions
Lower energy is anti-extrusion without being easily extruded crack；The component maximum to the contribution of fluid sealant non-deformability is polyurethane and metal powder
End, polyurethane is disperseed under the hot conditions more than 200 DEG C and is uniformly mixed with components such as pitch, glass fibre, rubber, is then dropped
Low temperature, metal dust is added into system, and metal dust disperses not reacting only in system at this time, should using
During Road sealant, because being hot type Road sealant, need fluid sealant being heated at more than the 190 DEG C progress cementation of fissures
Reason, metal dust can react with the double bond in polyurethane at this time, when gradually being cooled down after glue filling chink to be sealed, with metal
The polyurethane of powdered reaction cures, and can obtain the pointing of high rigidity, be not susceptible to deformation；Deposited at the same time in cured polyurethane
In continuous glass fibre as elastic skeleton, it can make sealant that there is elastic and certain ductility under severe cold weather, drop
Low embrittlement.
