Sound absorbing decorative gypsum board and production method thereof

Abstract

The invention provides a sound absorbing decorative gypsum board and a production method thereof, and relates to a decorative panel. The sound absorbing decorative gypsum board comprises an aluminiumfoil (1), a paper-faced gypsum board (2), and an embossing relief (3). The paper-faced gypsum board (2) is prepared by the following raw materials according to the proportioning rate: 60 parts of desulfurization gypsum, 4 parts of modified starch, 1 part of foaming agent, namely lauryl sodium sulfate, 1 part of glass fiber and 34 parts of water. The product is manufactured by the following steps:rotary drum embossing, film adhering of coating and drying. Compared with the existing sound absorbing board with the material quality, such as sound absorbing fiber or mineral wool and the like, thesound absorbing decorative gypsum board has the advantages of simple manufacturing process, high strength, dampproof performance, long service life and good effect of noise reduction and sound absorption.

Description

technical field [0001] The invention relates to decorative boards for buildings, in particular to a sound-absorbing decorative gypsum board and a production method thereof. Background technique [0002] Existing building decoration sound-absorbing design generally adopts three-dimensional sound-absorbing, or directly uses fiber sound-absorbing panels, mineral wool sound-absorbing panels, and silicon-calcium panels. These measures have the disadvantages of complex construction, high project cost, and slow progress. Among them, fiber sound-absorbing panels and mineral wool sound-absorbing panels have good sound-absorbing and noise-reducing properties, but due to the influence of their constituent substrates, their impact resistance and water resistance are poor, and the board surface will sag and yellow over time. and other phenomena, the decorative effect is reduced and the service life is short; the calcium-silicon board has good flame resistance, impact resistance and durab...

Problems solved by technology

[0002] The sound-absorbing design of existing building decoration generally adopts three-dimensional sound-absorbing, or directly uses fiber sound-absorbing panels, mineral wool sound-absorbing panels, and silicon-calcium panels. These measures have the disadvantages of complex construction, high project cost, and slow progress.

Among them, fiber sound-absorbing panels and mineral wool sound-absorbing panels have good sound-absorbing and noise-reducing properties, but due to the influence of their constituent substrates, their impact resistance and water resistance are poor, and the board surface will sag and yellow over time. and other phenomena, the decorative effect is reduced and the service life is short; the calcium-silicon board has good flame resistance, impact resistance and durability, but its weight is heavy, construction is inconvenient, efficiency is low, and its price is high, which is not conducive to popularization and use.

The existing decorative sound-absorbing panels are prone to moisture and deformation, which is difficult to solve for a while
