[0037] Test detection of performance parameters of wallboard composite material prepared by the invention:

[0038] Comparative test: PVC panels commonly used in the market; wall panels prepared in Example 1 of the present invention; all with a thickness of 10 mm as an example. The water absorption rate is determined as follows: accurately weigh the weight of the completely dry test block with a balance m, then put the test block 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 block again The weight n is obtained by multiplying (nm) / m by 100% to obtain the water absorption; the compressive strength refers to the B / T17669.3-199 standard; the sound insulation detection refers to the "classification and detection method of air 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...
