preparation example Construction
[0025] In another aspect of the present invention, the present invention provides a preparation method of the aforementioned electromagnetic radiation absorbing material for construction. According to an embodiment of the present invention, refer to figure 1 , the preparation method of electromagnetic radiation absorbing material for building comprises:
[0026]S100: Evenly stirring the wave absorbing agent and the porcelain stone particles, so as to attach the wave absorbing agent to the surface of at least a part of the porcelain stone particles. Therefore, the wave absorber can be more smoothly and quickly attached to the surface of the porcelain stone particles under the stirring condition.
[0027] According to an embodiment of the present invention, the step of uniformly stirring the wave absorber and the porcelain stone particles includes: stirring the wave absorber and the porcelain stone particles in a mixer for 30 to 40 minutes, such as 30 minutes, 32 minutes, 34 mi...
Embodiment 1
[0037] The steps of preparing the porcelain stone-based electromagnetic radiation absorbing material for construction include:
[0038] Screen the porcelain stone particles with a particle size of 0.5 to 2 mm;
[0039] Mix 200 mesh graphite and porcelain stone particles in a mixer for 30 minutes at a rate of 100 rpm;
[0040] The product of mixing graphite and china stone particles and Portland cement are continuously stirred in a mixer for 30 minutes to obtain a mixed powder, wherein the volume ratio of Portland cement, porcelain stone particles and graphite is 1:3:1;
[0041] The mixed powder and water were mixed in a volume ratio of 1:2 and stirred for 6 minutes, so as to obtain an electromagnetic radiation absorbing material for construction.
[0042] The electromagnetic radiation absorbing material for construction prepared in Example 1 was coated on the base material to obtain an electromagnetic radiation absorbing layer with a thickness of 1 mm. SE / dB), see the test r...

Abstract
The invention provides an electromagnetic radiation absorbing material for construction based on porcelain stone and a preparation method thereof. The electromagnetic radiation absorbing materials for construction based on porcelain stone mainly include: gel materials, porcelain stone particles and wave absorbers. The gel material mainly ensures the mechanical properties of the porcelain stone-based electromagnetic radiation absorbing material for construction; the porcelain stone particles are dispersed in the gel material, which can improve the electromagnetic impedance matching of the building material, and help electromagnetic waves in the building. scattering inside the material, and provide an attachment surface for the absorbing agent; the absorbing agent is attached to the surface of at least a part of the porcelain stone particles, which can increase the contact area between the absorbing agent and the electromagnetic wave per unit volume, and then more effectively realize the electromagnetic wave. absorption and attenuation to achieve the best electromagnetic absorption effect. The construction material preparation method has simple process and is suitable for large-scale production. The building material is convenient for preparation and construction, and after being coated on the building, it is also convenient for later maintenance.
Description
technical field [0001] The invention relates to the technical field of construction, in particular, to a porcelain stone-based electromagnetic radiation absorbing material for construction and a preparation method thereof. Background technique [0002] With the advent of the information age, the application of electromagnetic radiation in medical, industrial and communication industries has become increasingly widespread, and the impact of electromagnetic radiation on human health has attracted widespread attention. Physical protection is the most direct and effective way to protect against electromagnetic radiation for professionals who work in electromagnetic radiation environment for a long time and the public who live in electromagnetic radiation environment for a long time. Among them, buildings constructed with electromagnetic radiation absorbing materials can effectively protect the people who work or live in them. However, the cost of the existing electromagnetic ra...
