Description
Technical field
The invention belongs to road maintenance field of material technology, and in particular to a kind of high polymer chance water for crack repairing
Sealing material and preparation method thereof is in particular to used for cement concrete cracks, joint-cutting, asphalt concrete pavement, road
Crack recovery project in terms of bridge.
Background technique
Cement concrete pavement is one of the road surface of most widely used application in highway engineering.In actual use, due to
Concrete quality is bad, construction wrong, weather, the hydration reaction of cement, the drying shrinkage action of cement concrete and temperature stress etc.
Reason, it is the main reason for influencing service life of road surface that cement concrete pavement, which generates disease caused by crack and joint-cutting,.
Asphalt concrete pavement is most widely used another kind road surface in highway engineering.In actual use, ground
The reasons such as base and foundation settlement difference, Material shrinkage, pitch and the contracting of coagulation soil temperature cause transverse crack；Ground, subgrade construction, water
Infiltration erosion damage, connect the reasons such as stubble and cause longitudinal crack；Unreasonable, ageing of asphalt and automobile is designed seriously to overload, occur
Laterally or longitudinally the reasons such as packing cause chicken-wire cracking not in time in crack.If these cracks are handled not in time, road will affect
Normal usage function.
If these crack diseases cannot be repaired timely, it will lead to more serious pavement disease, serious shadow
Service life of road surface is rung, will finally pave the way again less than in design period, and cause more huge economic loss.Therefore, in order to prolong
The service life on long concrete road surface increases its service life, studied from the Producing reason in crack it is a kind of it is organic with it is inorganic
The hard and soft patching material combined, preferably applies and repairs in cement concrete pavement, asphalt concrete pavement and road and bridge
Equal more areas again.
Currently, cement pavement and bituminous pavement have respective crack repairing glue, it can be not only applicable in cement pavement, but also can use
In bituminous pavement crack repairing glue report and it is few.Cement pavement crack patching material mainly has inorganic and organic two major classes.
Organic material includes epoxy resin, polyurethane, water expandable waterstop, rubber asphalt etc., but generally existing durability is poor, high temperature
The disadvantages of easy fracture, aging and higher cost.Inorganic material includes geopolymer, fast setting concrete etc., but there is repairing interface
Linking new and old concrete performance is poor, and most of is all finished product, and no and slotted wall carries out any physical-chemical reaction, and open to traffic
The limitations such as the time is longer.There are mainly three types of the crack repairings of bituminous pavement: hot type casting glue, normal temperature type casting glue, chemistry
Class casting glue.Hot type casting glue has modified pitch, rubber asphalt, fiber asphalt, has performance good, open to traffic morning etc. excellent
Point, but its complicated construction technique, heating temperature is high, is easy to produce pernicious gas etc. and is gradually replaced by normal temperature type casting glue；Often
Warm type casting glue is mainly emulsified asphalt, biggest advantage be can construct at normal temperature, time is short, construction technology is simple
It is single, but de-emulsification speed is influenced by environmental temperature, causes open to traffic late by certain limitation；Chemical classes casting glue master
If thio resin class and silicones class, are easy to produce environmental problem.Need to develop at present a kind of organic high polymer with it is inorganic
Powder obtains one kind by physical-chemical reaction and is suitble to various types of cracks repair materials particularly important.
In the prior art, a kind of geopolymer base cement pavement crack is mentioned in Chinese patent CN108424087A quickly to repair
Material is mended, most prominent advantage is intensity height, but its raw material complex process, operation difficulty are high, and main raw material(s) is nothing
Machine binder, does not have flexibility；And the production of powder is generally intended to simple process, raw material are easy to get, and crack glue has
Certain flexibility.
Acrylic compounds patching material has many advantages, such as that viscosity is low, curing time is fast, but is typically all to polymerize organic high score
Sub- material is suitble to bituminous pavement, is unfavorable for environmental protection and the cracks such as cement pavement, and that there are volume contractions is big, ageing time is short
Problem.
