Abstract

The invention discloses a high-strength keelless La Nina mineral wool board, prepared by mixing a slurry A and a slurry B in equal proportion and stirring uniformly, molding, drying, conducting surface treatment, and packaging. According to the invention, the produced La Nina mineral wool board needs no keel and is directly stuck onto roofs and wall surfaces, and has the effects of tidiness and beauty; the produced La Nina mineral wool board has the advantages of high strength, no warp, no deformation, environmental protection, and recyclable property, and effectively solves the technical problems of need for keel fixation, easiness in warp and deformation, etc. in existing ceiling.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a keelless mineral wool board. Background technique [0002] Mineral wool board generally refers to mineral wool decorative sound-absorbing board, which is a building decoration material processed by molding, drying, cutting, embossing and other processes with mineral wool as the main raw material and adding an appropriate amount of binder. Mineral wool board has excellent fireproof, waterproof, moisture-proof, sound insulation, heat insulation, easy deep processing and other properties. It is widely used in decorative ceilings of public buildings, and can also be used in industrial plants, high-end residences and high-rise buildings. However, at present, most of the mineral wool boards produced in China need to be fixed by keels, and they also have disadvantages such as low strength, easy warping, and deformation. Contents of the invention [0003] The purpose of the present ...
