Abstract
The invention discloses a cement matrix wave-absorbing construction material which is prepared by taking cement as a matrix and adding 55-65 parts of organic wave-transparent aggregate, 8-12 parts of dielectric loss wave-absorbing agent, 0.5-1 part of auxiliary enhancement wave-absorbing agent and 25-35 parts of electromagnetic loss wave-absorbing agent into every 100 parts of cement matrix. In such manner, the cement matrix wave-absorbing construction material disclosed by the invention can effectively shield the radiation of electromagnetic waves to a human body, achieves the purpose of purifying the environment polluted by electromagnetic waves, has favorable wave-absorbing property, stability quality and mechanical property, and is wide in frequency band and low in cost.
Description
Technical field
The present invention relates to the building decoration technology field, particularly relate to a kind of cement matrix and inhale the wave building material.
Background technology
Develop rapidly along with the hyundai electronics science and technology, electronics high frequency, digitizing, electromagnetic radiation etc. are when creating the wealth to the mankind, brought more and more serious harm also for equipment, system and ecotope, therefore, by internationally recognized for being the 4th large public hazards after topsoil, water pollution and sound pollution.In order to prevent outside electromagnetic interference and the leakage of electromagnetic signal, cut down hertzian wave to the injury of human body and the hertzian wave detectivity to buildings, the purifying electric magnetic radiation improves the space electromagnetic environment, eliminate electromagnetic pollution, need to carry out electromagnetic protection to buildings.
At present, mainly adopt wave-absorbing material applied to buildings effectively to realize the electromagnetic protection of buildings.Cement is for carrying and keeps building shape and use comparatively widely material of construction, but, plain cement does not have the shielding electromagnetic waves sorption, usually adopt electromagnetic shielding material to come filling concrete to make it can effectively suppress electromagnetic radiation and leakage, but this material just goes back reflection of electromagnetic wave usually, cause easily secondary pollution, and can not fundamentally weaken and eliminate hertzian wave.And existing absorbing material have frequency band narrow, absorb that usefulness is low, cost is high, the defective such as poor stability, environmental adaptation are poor.
Summary of the invention
The technical problem that the present invention mainly solves is: for the deficiencies in the prior art, provide a kind of cement matrix to inhale the wave building material, shielding electromagnetic wave is to the radiation of human body effectively, reach and purify by the purpose of the environment of Contamination of Electromagnetic Wave, have good absorbing property, stability and mechanical property, and bandwidth, cost are low.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of cement matrix to inhale the wave building material, it is take cement as base material that described cement matrix is inhaled the wave building material, adds organic wave transparent aggregate, the dielectric loss wave absorbing agent of 8-12 part, the auxiliary enhancing wave absorbing agent of 0.5-1 part and the electromagnetic consumable wave absorbing agent of 25-35 part of 55-65 part and make in per 100 parts of cement matrixs.
In a preferred embodiment of the present invention, described organic wave transparent aggregate is closed-cell expanded perlite.
In a preferred embodiment of the present invention, described dielectric loss wave absorbing agent is graphite microparticles.
In a preferred embodiment of the present invention, described auxiliary enhancing wave absorbing agent is continuous basalt fiber.
In a preferred embodiment of the present invention, described electromagnetic consumable wave absorbing agent is a kind of in polycrystalline iron fiber, steel fiber, carbon fiber or the ceramic fiber.
The invention has the beneficial effects as follows: by the organic wave transparent aggregate of reasonable selection, dielectric loss wave absorbing agent, auxiliary wave absorbing agent and the electromagnetic consumable wave absorbing agent of strengthening, adopt rational proportioning to make cement matrix and inhale the wave building material, shielding electromagnetic wave is to the radiation of human body effectively, reach and purify by the purpose of the environment of Contamination of Electromagnetic Wave, have good absorbing property, stability and mechanical property, and bandwidth, cost are low.
