Abstract

The invention discloses a sound absorption plate and a preparation method thereof. The sound absorption plate is prepared from the following raw materials in parts by weight: 30 to 50 parts of gypsum powder, 20 to 30 parts of bamboo carbon fiber, 8 to 15 parts of glass fiber, 1 to 5 parts of attapulgite clay, 5 to 10 parts of blast furnace slag, 1 to 3 parts of magnesium oxide, 0.6 to 2.8 parts of an inorganic adhesive, 0.5 to 1.6 parts of a water repellent and 0.2 to 0.8 part of a flame retardant. The preparation method of the sound absorption plate comprises the steps of purification of the attapulgite clay, preparation of a substrate material, preparation of a molding blank and natural maintenance. The components of the sound absorption plate are safe and environment-friendly, and the sound absorption plate is good in waterproofing and flame retardancy effect and can isolate sound and heat; the intensity and the hardness of a gypsum board are retained.

Description

technical field [0001] The invention relates to the field of decorative materials, in particular to a sound-absorbing panel and a preparation method thereof. Background technique [0002] Sound-absorbing panel is an ideal sound-absorbing decorative material, which has the advantages of sound absorption, environmental protection, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, mosaic, simple construction, good stability, good impact resistance, and high cost performance. There are a variety of colors to choose from, which can meet the needs of different styles and levels of sound-absorbing decoration. Among them, gypsum board is a commonly used sound-absorbing board, which is widely used in building decoration materials because of its light weight, high strength, sound insulation, heat insulation, fire prevention, and easy processing. [0003] The invention patent of authorized notification number CN 104386999B discloses a fire-pro...
