Nonflammable light-weight panel by advancing the water-proofing and wear resistance and producing method thereof

Abstract

The present invention relates to a nonflammable light-weight panel by advancing the water-proofing and wear resistance and a producing method thereof. In the present invention, expanded perlite is used to improve the water-proofing and wear resistance. The nonflammable light-weight panel is manufactured by three steps: a fixing molding step of molding a lightweight product into a specific shape by mixing a power binder consisting of gypsum hemihydrate and white cement, water, and expanded perlite; a curing step of curing the molded product at 60-120 degrees C for 1-2 hours; and a surface reinforcing step of forming a surface-reinforcing layer by spreading a magnesia phosphate salt-based spreading agent onto the surface of the cured product. The nonflammable light-weight panel provided by the utility model can reduce the fixed load of buildings, improves the fire-proofing and flame retardation performance for fire fighting, and improves the heat insulation and sound insulation properties and convenience of construction, thereby being applicable to inner walls and outer walls of buildings for thermal insulation, heat insulation, sound insulation, moisture resistance and antibacterial effects.

Description

technical field [0001] The invention relates to a strong water-resistant, wear-resistant, flame-retardant light-weight board manufacturing material and its manufacturing method, which can reduce the fixed load of the building, enhance the fire resistance and flame retardancy corresponding to fire, improve heat insulation, sound insulation and The construction is convenient, so the inner and outer walls used in buildings can be insulated, not conductive, and can prevent fires. Background technique [0002] Recently, the world's requirements for light weight and fire resistance of buildings are increasing day by day, especially for internal partition walls and decorative panels of buildings, as well as external decorative walls and decorative panels. For this reason, the lightweight sandwich Light hardened bodies such as boards, ALC boards / blocks, lightweight aggregates (expanded perlite or expanded vermiculite, etc.). [0003] The above-mentioned lightweight sandwich board i...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned lightweight sandwich board is made of materials such as foamed polystyrene or urethane, which is very light, relatively cheap, and has very good thermal insulation performance, so it is the main building material commonly used in industrial buildings. However, as verified by previous fire cases, Because the material is relatively flammable, when a fire breaks out, the flame spreads rapidly and is difficult to control. What's worse is that a large amount of harmful gas is produced during combustion, which can cause people to suffocate and die. There are many other problems.

[0004] The above-mentioned ALC board / block is aerated concrete made of raw materials such as silicon dioxide, lime and foaming agent through high temperature and high pressure. It absorbs water easily, so it has poor water resistance and is not suitable for places affected by moisture, which is its disadvantage

[0005] The above-mentioned lightweight hardened body using lightweight aggregate (expanded perlite or expanded vermiculite, etc.) is made by combining lightweight aggregate with various binders (cement, gypsum, or sodium silicate, etc.). Lightweight, heat insulation, sound insulation and other characteristics, no toxic gas will be released in case of fire, but the water absorption (wet) is relatively strong, the hardness is not enough, so the wear resistance and scratch resistance are not good, easy to break, the surface is uneven, The adhesion of the corners is low, so the corners are easily damaged during handling and construction, which is its shortcoming
