Description
Technical field
The invention belongs to the interleaving techniques field of architectural materials science and electromagnetism science, relate to a kind of light skeletal of using float stone and pearlstone preparation and inhale ripple thermal insulation concrete material and preparation method thereof.
Background technology
Concrete is the maximum material of construction of usage quantity in the current construction work; In order to alleviate buildings deadweight, improve the building thermal-insulation energy-saving effect, to eliminate electromagenetic wave radiation, become the focus of current research for the research of the suction ripple of concrete material and heat-insulating property.At present; Research for the concrete absorbing material both at home and abroad mostly concentrates on materials such as in normal concrete, adding metal-powder, ferrite, fiber, powdered carbon, whisker; Though can improve its absorbing property; But owing to reduced the matching degree with the spatial wave impedance simultaneously, thus the concrete absorbing material of development effectively to inhale the ripple frequency range narrower, the wave absorbing agent absorbing property is low.Do not improve for the characteristics from great, heat-insulating property difference of concrete material in addition yet, can't in the buildings of reality, promote the use of.
Summary of the invention
The invention provides a kind of float stone pearlstone complex building functional materials and preparation method thereof; It utilizes big, widespread float stone of reserves and pearlstone to do aggregate; Utilize general purpose portland cement to do consolidating material; Add the composite multifunction material of construction that radio-radar absorber is processed, have light weight, inhale characteristics such as the ripple frequency range is adjustable, good heat insulating.
Technical scheme of the present invention is following: a kind of float stone pearlstone complex building functional materials is to be the building function material that coarse aggregate and fine aggregate are processed with float stone and pearlstone; Comprise dry material and water, dry material comprises cement, float stone, pearlstone, wave absorbing agent; The weight ratio of cement, water, pearlstone, pumice aggregate, wave absorbing agent is 1: 0.50～0.60: 0.1～0.2: 1.0～2.0: 0.01～0.05.
Pumice aggregate is a natural pumice, particle diameter 5～10mm, and porosity is more than 70%, and pore size distribution is between 7 μ m-140 μ m, and self ultimate compression strength is greater than 4MPa.
Further characteristic, wave absorbing agent can be selected one or more mixing in carbon black, iron carbonyl, ferrite, the superfine iron powder for use.
Pearlstone can be selected particle diameter 0.1-5mm for use, and grating is reasonable, tap density 40～80kg/m
3Pearlstone.
Cement can adopt general purpose portland cement.
Further characteristic is intensity and the toughness that improves above-mentioned complex building functional materials, but also an amount of high efficiency water reducing agent of admixture is cut polypropylene fibre with weak point.
The step for preparing above-mentioned complex building functional materials is:
(1) wave absorbing agent is joined in the cement stirs;
(2) pearlstone is added stirrer and cement, wave absorbing agent stir together; Or polypropylene fibre added stirrer with pearlstone and cement, wave absorbing agent stir together;
(3) stir in the saturated back adding of the pumice aggregate suction stirrer;
(4) add entry or add entry and the mixture of high efficiency water reducing agent separately;
(5) material after will stirring injects mould, waters mold forming, and the demoulding becomes the complex building functional materials goods of net shape.
Test the absorbing property and the heat-insulating property of this complex building functional materials, verify that it is to the absorption of electromagnetic wave ability.Test adopts arc reflection method in no echo darkroom, to carry out, and test result is with absorbing usefulness (dB) expression.Products thickness is different; Prescription is different; Receptivity is also different with the absorption bandwidth, is 1: 0.60: 0.2 with cement, water, pearlstone, pumice aggregate, sooty weight ratio: 1.5: 0.03 preparation compounds, and molding thickness is that the goods of 25mm are example; The thermal conductivity test result is 0.206W/mK, and the absorption of electromagnetic wave performance is shown as follows:
| Frequency, GHz | 2 | 3 | 4 | 5 | 6 | 8 | 9 | 10 | 11 |
| Absorb usefulness, dB | 0.6 | 0.1 | 4.7 | 2.2 | 11 | 10.5 | 6.6 | 7.3 | 13.2 |

| Absorb usefulness, dB | 7.6 | 15.6 | 10.8 | 14.6 | 12.2 | 11.2 | 14.5 |
Effect of the present invention and benefit are:
(1) adopt natural pumice and pearlstone as coarse aggregate and fine aggregate, wide material sources, cheap, be fit to large-scale engineering applications.
(2) because float stone and pearlstone have flourishing pore texture, and apparent density is lower, thereby institute's concrete batching density is low, heat-insulating property is good simultaneously.
(3) production technique of the present invention is simple, does not need specific equipment, and with portland cement concrete basically identical, starting material wide material sources, the finished product price is low, can realize industrialization production.
(4) float stone pearlstone complex building functional materials of the present invention, it is good to have an absorbing property, and it is wide to absorb frequency range, the characteristics of good heat insulating.Those skilled in the art can obtain the float stone pearlstone complex building functional materials of the present invention of different performance through adjustment proportioning and wave absorbing agent volume.
(5) complex building functional materials of the present invention can be done cast-in-situ wall, roof, also can process concrete product, like wallboard, building block, roof boarding etc., has insulation and absorbing property concurrently.
