Problems solved by technology

Hazard 4: High doses of electromagnetic radiation will also affect and destroy the original bioelectric current and biomagnetic field of the human body, making the original electromagnetic field in the human body abnormal
[0004] For the above-mentioned technical problems, anti-radiation wall panels have been studied in the prior art. For example, the Chinese patented technology "light-weight anti-radiation thermal insulation wall panels" discloses a kind of anti-radiation wall panels. Its composition includes: cement layer, benzene board layer, graphite layer , the benzene plate layer and the graphite layer are embedded in the cement layer, the two sides of the benzene plate layer are respectively coated with the graphite layer, and the cement layer is horizontally arranged with Barbed wire; the preparation method of the above-mentioned wall panels is cumbersome, and the radiation protection effect is poor

[0037] The performance parameter test detection of the wallboard composite material prepared by the present invention:

[0038] Comparative test: PVC boards commonly used in the market; wallboards prepared in Example 1 of the present invention; both take 10mm thickness as an example. Determination of water absorption: use a balance to accurately weigh the weight m of a completely dry test piece, then soak the test piece in water at about 30 degrees Celsius, take it out of the water after 1 hour, wipe off the surface moisture with a dry towel, and weigh the test piece again. Weight n, water absorption rate is obtained by multiplying (n-m) / m by 100%; compressive strength refers to B / T17669.3-199 standard; sound insulation test refers to "Classification and Testing Method of Airborne Sound Insulation Performance of Building Doors and Windows" GB / T 8485-2008, see Table 1 for specific results.

Abstract

The invention belongs to the field of a building material, and discloses a ray-proof composite wallboard for an electric power dispatching machine room. The ray-proof composite wallboard comprises the following raw materials in parts by weight: 1-2 parts of a ray-proof agent,1-2 parts of a fire retardant, 2-3 parts of a foaming agent, 3-5 parts of graphite powder, 30-50 parts of polypropylene resin, and 50-70 parts of polystyrene particles. The composite wallboard has good flame retardation and insulation effects, has good electromagnetic shielding function, and is suitable for being used in the electric power dispatching machine room.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a radiation-proof composite wallboard for a power dispatching machine room. Background technique [0002] The power dispatching room generally refers to the place where servers are stored in telecommunications, Netcom, mobile, dual-line, electric power, government or enterprises, etc., and IT services are provided for users and employees. The small ones are tens of square meters, and generally twenty or thirty cabinets are placed. There are thousands of cabinets, or even more, in a large tens of thousands of square meters. Various servers and minicomputers are usually placed in the computer room, such as IBM minicomputers, HP minicomputers, SUN minicomputers, etc. The temperature and humidity of the computer room and the anti-corrosion Static radiation protection measures have strict requirements, and non-professional project personnel are generally not allowed to ente...
