Description of the drawings
Fig. 1 is the flow chart of the preparation method of the concrete finishing slab of an embodiment.
Specific embodiment
For the ease of understanding the present invention, the present invention is described more fully below with reference to relevant drawings.In accompanying drawing
Give the preferred embodiment of the present invention.But, the present invention can be realized in many different forms, however it is not limited to herein
Described embodiment.On the contrary, the purpose for providing these embodiments is to make the understanding to the disclosure more saturating
It is thorough comprehensive.
The invention provides the concrete finishing slab of an embodiment.The concrete finishing slab includes concrete, boundary
Surface layer and decorative layer.
The raw material of concrete includes concrete and phase-change accumulation energy granule.The quality of phase-change accumulation energy granule and concrete
Than for 2%～10%.Phase-change accumulation energy granule is added in concrete so that the concrete of formation is in temperature compared with Gao Shitong
Cross phase-change accumulation energy granule and undergo phase transition heat absorption, when indoors temperature is relatively low, phase change grains can be released heat by phase transition process again
Release, so as to improve the cold-resistant heat resistance of its own, and then improve its durability.The concrete finishing slab is especially fitted
Use in interior, so as to play a part of constant room temperature, improve comfort level.In addition the mass content of phase-change accumulation energy granule needs tight
Lattice are controlled, it is to avoid add the intensity of excessive impact concrete.It is furthermore preferred that the quality of phase-change accumulation energy granule and concrete
Than for 3%～7%.
Preferably, the water absorption rate of hydroscopic high-molecular resin is 300-500 times.
In another embodiment, the raw material of concrete also includes hydroscopic high-molecular resin.Hydroscopic high-molecular resin
It is 2%～5% with the mass ratio of concrete.Hydroscopic high-molecular resin is added in concrete so that the xoncrete structure of formation
Layer is larger in humidity or have the environment of water in a large number to absorb moisture, and can maintain moisture and do not outflow, and can also compare
Dry environment increases the dampness of environment, and then improves the durability of concrete finishing slab.The concrete finishing slab is particularly suitable for
Interior uses, and then can preferably adjust the humidity of interior, improves comfort level.It is furthermore preferred that hydroscopic high-molecular resin and coagulation
The mass ratio of soil is 2.5%～3.5%.Preferably, hydroscopic high-molecular resin is the hydroscopic high-molecular resin through soaked process,
Hydroscopic high-molecular resin can so be made in water suction poised state, it is to avoid mix dry hydroscopic high-molecular resin with concrete
Cause it to be combined with the water in concrete and then affect the performance of concrete or because water suction volume expansion causes xoncrete structure
Layer problems of crack.It is furthermore preferred that the time of soaked process is 0.5～2h.
In another embodiment, the raw material of concrete also includes aglite.The matter of aglite and concrete
Amount is than being 2%～10%.Aglite is added in concrete so that the deadweight of the concrete of formation is reduced, and then
Improve the portability of concrete finishing slab, it is to avoid itself because deadweight causes to come off the problems such as breakage, while aglite is also
With deadening.It is furthermore preferred that the mass ratio of aglite and concrete is 3%～7%.Preferably, aglite is glass
Change microballon and at least one in granular polystyrene.It is furthermore preferred that the particle size range of aglite is 40～70 mesh.
So concrete finishing slab is by resistance to water, thermostability and mitigates the combination of many aspects such as deadweight, improves durable
Property.The concrete finishing slab is particularly well-suited to interior decoration, can increase substantially the comfort level of interior.
Preferably, concrete is super high strength concrete, and concrete is super high strength concrete structure sheaf, and then is ensured
It has preferable mechanical property and weather resistance.The concrete of grade of compressive strength C100 and the above is thought into superelevation in industry
Reinforced concrete.On the one hand because super high strength concrete intensity is high and degree of compaction is big, therefore the rupture of phase-change accumulation energy granule can be reduced
Rate, even if its rupture can also avoid the phase-change material seepage in phase-change accumulation energy granule；Another aspect super high strength concrete is due to this
Body has certain viscosity, and it need not add cellulose ether to improve viscosity, using super high strength concrete and phase-change accumulation energy granule
Directly mix, just can prevent phase-change accumulation energy granule from floating, and then ensure that it is uniformly dispersed in concrete.Preferably,
Concrete is 3～8mm.
Preferably, phase-change accumulation energy granule is phase-change microcapsule.Boundary layer is for network structure and located at concrete.Boundary
Surface layer can Concrete Structure decorative panel intensity, and then the thickness of concrete finishing slab can be reduced.In addition boundary layer is netted knot
Structure, so that concrete can be connected with decorative layer.
Preferably, boundary layer is at least one in fibrous mesh cloth and bar-mat reinforcement.
Decorative layer is on boundary layer.The raw materials by weight portion meter of decorative layer, including 300～550 parts of cement, 20～40
700～950 parts of mesh quartz sand, 240～310 parts of 40～70 mesh quartz sand, 15～22 parts of water reducer, 0.1～0.7 part of cellulose ether
And 190～240 parts of water.Wherein by taking 20～40 mesh quartz sands as an example, screen size is referred to, that is, 20～40 mesh sieves can be passed through
The quartz sand of the particle diameter in mesh screen hole.
The raw material of above-mentioned decorative layer is high with the decorative layer intensity that level is obtained, and cellulose ether can improve decorative layer each component
Between cohesive force and water retention property, and then play a part of to prevent the bleeding that ftractures and prevent.In addition the decorative layer and concrete
Structure sheaf solidification connection fastening, it is to avoid easy to crack under the adverse circumstances that thermal coefficient of expansion difference between layers is caused and stripping
From problem, further increase the intensity of concrete finishing slab, reduce its breakage rate, and then improve its durability and subtract
Little its thickness, is effectively reduced later maintenance workload, reduces cost.
It is furthermore preferred that the raw materials by weight portion meter of decorative layer, including 350～500 parts of cement, 20～40 mesh quartz sands
750～850 parts, 250～290 parts of 40～70 mesh quartz sand, 16～18 parts of water reducer, 0.4～0.6 part of cellulose ether and water 190
～220 parts.Wherein by taking 20～40 mesh quartz sands as an example, screen size is referred to, that is, 20～40 eye mesh screen sieve apertures can be passed through
Particle diameter quartz sand.
Preferably, cement is white cement.
Preferably, water reducer is polycarboxylate water-reducer.
Preferably, the raw materials by weight portion meter of decorative layer, also including 290～330 parts of 325 mesh quartz sand.Using 20～
The level of 40 mesh quartz sands, 40～70 mesh quartz sands and 325 mesh quartz sands matches somebody with somebody quartz sand, is conducive to the tightly packed of slurry component,
According to the available higher mechanical strength of theory of high packing.Secondly the mechanics that the quartz sand of this three classes particle size range is not only obtained
Performance is good, and its Financial cost is low.It is furthermore preferred that 325 mesh quartz sands are 300～310 parts.
Preferably, the raw materials by weight portion meter of decorative layer, also including 2～8 parts of phase-change accumulation energy granule.So can be further
The cold-resistant heat resistance of Concrete Structure decorative panel and the effect of its constant room temperature.Additionally, the decorative layer intensity that should match somebody with somebody level is high,
Degree of compaction is big, it is possible to decrease the rupture rate of phase-change accumulation energy granule, even if its rupture can also avoid the phase transformation material in phase-change accumulation energy granule
