Description
Technical field
The present invention relates to a kind of ground surface material and preparation method thereof, especially a kind of colored road surface material and its preparation side
Method.
Background technology
Colored road surface has the function of beautifying the environment and warning traffic.Colored road surface is widely used for prompt road in Europe
Which part road user can use period in which.It is widely used in providing an individual vehicle in European colored road surface
Special road user is given in road, such as is exclusively used in the bus zone of public transport, cycle track, and equipment of small motor track is special
The electronic charging station track of holder is demonstrate,proved in emergency services and honored guest.Colored road surface carries out the differentiation of color in some deceleration strips.
It is very practical to distinguish in this way.Traffic violations can be effectively reduced, traffic driving safety is increased.In addition, colored road surface
The universal city that can largely take on a new look image, embody the characteristic in city.It is not only embodied in the apparent change in city,
It is also embodied in the change of urban residential environment.City noise pollution can be made to reduce, this is because Colorful Asphalt Pavement has preferably
Sound-absorbing effect, be effectively improved highway get on the car noise the phenomenon that.
Have many researchs both at home and abroad about colored road surface material, main achievement is：
1）Color paving cementitious matter is made in the pigment of color required for the decoloration of common albertite is added again, then does bone with natural stone
Material is mixed with colored road surface material；
2）Color paving cementitious matter is made with Petropols+polymer+aromatic oil+pigment etc., then does aggregate with natural stone and mixes
Colored road surface material is made in conjunction；
3）Reaction-curable coloured silk is made with resin+curing agent+dilution toughener and spreads cementitious matter, then gathers materials with colour and mixes system
At colored road surface material.
The first is with second of color the characteristics of spreading cementitious matter：It is required for producing under the high temperature conditions, complex process, cost
High, production process pollutes environment and color stone color is not bright-coloured, lasting.
For the third colored road surface material, CN102464863A discloses a kind of color pavement cementing material and its application,
Bisphenol A epoxide resin, polyamide curing agent and polypropylene glycol diglycidyl ether or benzyl alcohol are mixed in the patent
It is even, color pavement cementing material is made.Then gather materials with colour and be mixed and made into colored road surface mixture, for being laid with colored road surface.
While convenient for colored road surface making, the performance of color pavement cementing material is improved, extends the service life of colored road surface.
CN103924496A discloses a kind of laying method of colored ceramic particle anti-skid surface, on the road surface of dry cleansing
On, the good glue of beach mixing dispenses the ceramic particle polish resistant aggregate baked in advance, after dispensing uniformly, utilizes the viscous of primer
Attached property makes aggregate inlay closely, then extrusion face glue, to form the colored ceramic particle road surface of high intensity.
Coloured silk paving material belongs to face layer ground surface material mostly, it usually needs and it is bonding with basic road surface, and basic ground surface material
It is divided into different materials with colorful surface layer material, is made because of the inter-laminar stress that two kinds of material heat sensitivitys are different and generate so having
At pavement destruction problem.
CN102731018A discloses a kind of ceramic sand-like composite phase change material and preparation method thereof.Its by phase-change material with
Pottery sand presses quality 3：7 are uniformly mixed, and miberal powder is added in vacuum drying, obtains composite material.Composite material is immersed into epoxy emulsion, surface
Dispense iron powder.After phase-change material is added, temperature change can be effectively reduced by the phase transition process of phase-change material, and then avoid coloured silk
Color road surface is with basic road surface due to inter-laminar stress problem caused by material heat sensitivity difference.
Since pottery sand is used for road surface, the high-strength pottery sand using high compressive strength is needed.But existing high-strength pottery sand does not have
There is higher porosity, causes phase-change material that cannot all be absorbed by pottery sand, to cause phase-change material to be tied with cementitious matter
It closes, stress concentration phenomenon will occur at each transformation temperature when road surface stress, in turn result in road surface and seriously destroy.Furthermore
In the pottery sand for preparing high porosity, compression strength can be greatly reduced existing method, when being used for road surface, be easy to be rolled over by driving
It is broken.
Therefore, the ceramic particle of high porosity and high compressive strength how is prepared to absorb phase-change material, to avoid
Phase-change material occurs to combine with cementitious matter to be a problem to be solved.
