Abstract
The invention belongs to the technical field of graphite membrane application, and relates to a concrete material high in heat dissipation performance and used for the field having heat dissipation requirements such as underfloor heating and industrial pipeline. The concrete material includes, by weight, 20-25 parts of pebbles, 30-40 parts of cement, 5-15 parts of a graphite membrane, 1-3 parts of a water reducer, 1-2 parts of nanometer magnesium oxide and 1-2 parts of active calcium oxide, with the balance being water. The objective of the invention is to provide the concrete material high in heat dissipation performance. The strip-shaped, sheet or irregular-shaped graphite membrane is added into the concrete, and heat of a heat source can be rapidly dissipated on the graphite membrane, and therefore the overall heat of the concrete tends to be uniform, and temperatures of the concrete near the heat source and concrete far away from the heat source are homogenized.
Description
Technical field
The invention belongs to graphite film applied technical field, it is related to one kind, for floor heating, industrial pipeline etc., there is heat transfer requirement
Field high radiating concrete material.
Background technology
In recent years, graphite film material, because of characteristics such as its excellent high heat conduction, heat-resisting, corrosion-resistant and high connductivity, extensively should
For technical fields such as electronic product radiating, heat-resistant seal material, heaters.And the graphite film with high thermal conductivity is even more
Be widely used under smart mobile phone and panel computer equidimension, in the handheld terminal such as electronic component is intensive, caloric value is big, by height
Thermal conductivity realizes heat sinking function.
Cement layer in conventional concrete has thermal inertia, and when needing to carry out temperature adjustment, cement layer will delayed about 2-3
Hour just can respond, and loses thermoregulator meaning, therefore conventional cement layer has heat conductivility poor, and heat loss rate is high
's.At present with regard to adopting carbon fiber the heat conduction phase of heat-conduction concrete, carbon fiber price is higher, makes heat-conduction concrete after interpolation more
Cost up, for comparing carbon fiber, graphite acquisition is relatively easy, price is also cheap, has good heat conductivity and chemistry again
Inertia, therefore, graphite can as heat conduction phase material, although graphite can increase the heat conductivility of concrete to a certain extent,
But graphite is distribution in units of point in concrete, heat excessive for local can not be radiated rapidly, still there is thermal source
Nearby temperature is too high, and the concrete temperature away from thermal source is relatively low.
Content of the invention
It is an object of the invention to provide a kind of high radiating concrete material, concrete with the addition of strip or lamellar or not
The heat of thermal source can be spread rapidly on graphite film by the graphite film of regular shape, so that the overall heat of concrete is become
To in homogenization, make near heating sources temperature and the concrete temperature homogenization away from thermal source.
Technical scheme is as follows：
A kind of high radiating concrete material, including following components, each component is by weight：
Preferably, described graphite film is strip, lamellar or irregular shape graphite film.
Preferably, described graphite film is strip graphite film, the size of described graphite film is width 1-3mm, length 5-
30mm.
Preferably, described cobble is natural pebble.
Preferably, cobble for a diameter of 5-12mm for described cobble.
Preferably, described water reducer is polycarboxylate water-reducer.The compatibility with various cement is good, the slump of concrete
Keep performance good, extend the engineering time of concrete；Volume is low, and water-reducing rate is high, shrinks little, can increase substantially the morning of concrete
Phase, later strength, chloride ion content is low, alkali content is low, is conducive to the durability of concrete, and production process is pollution-free, without first
Aldehyde, meets ISO14000 Environmental protection management international standard, is a kind of Green Product.
Preferably, described active calcium oxide is prepared from through calcining by limestone, the particle diameter of described limestone is 80-90
μm, the temperature of described calcining is 900 DEG C～960 DEG C, and the time is 40-45min.Limestone from this kind of specification adopts this technique
The active calcium oxide of condition calcining preparation has excellent expansion effect, is added in cement, when cement setting hardens, therewith
Volumetric expansion, plays to compensate and shrinks and tension reinforcing steel bar generation prestressing force and the effect being sufficient filling with cement gap, and usage amount
Few.
Preferably, the mean diameter of described nano magnesia is 50nm.Nano magnesia is compounded with active calcium oxide,
Can make system in the case of extender usage amount is less, reach more excellent expansion effect.In the present invention, active oxygen
Change calcium and nano magnesia compounds, its total parts by weight just can reach excellent expansion effect under conditions of less than 3 parts.
The invention has the beneficial effects as follows：
A kind of high radiating concrete material of the present invention, with the addition of graphite film in concrete, can be rapidly by local mistake
The heat of heat is spread on graphite film, improves radiating effect and use intensity, and effectively reduces heat loss rate.
A kind of high radiating concrete material of the present invention, it is to avoid using higher materials of price such as carbon fibers, directly adopts
With strip, lamellar or difform graphite film, the cost of material can be reduced to a great extent.And graphite film can take
From producing the waste material cutting during graphite film, reduce further the production cost of concrete.
