Abstract

The invention discloses a composite sound insulation board and a production process thereof. The composite sound insulation board is prepared from the following raw materials in parts by weight: 35-40parts of bentonite, 6-15 parts of wood fibers, 5-10 parts of perlite particles, 4-8 parts of activated carbon, 6-11 parts of plant straw powder, 2-5 parts of light calcined magnesia, 3-7 parts of xanthan gum powder, 5-10 parts of expanded vermiculite, 5-7 parts of silica fume, 10-20 parts of polyacrylamide and 5-9 parts of a binder. According to the composite sound insulation board, the characteristics of the bentonite are utilized, common pollutants in air can be adsorbed, and the prepared sound insulation board is good in sound insulation effect, has heat preservation and waterproof performance, is free of radioactive elements and does not generate toxic gas; the composite sound insulation board is simple in preparation process and suitable for industrial mass production; the raw materials are easily available and environment-friendly and accord with the green development trend of China; the composite sound insulation board also has the characteristics of corrosion resistance, moisture resistance, worm damage resistance, no deformation and the like, and can be widely applied to walls, wallboards and sound insulation boards in buildings.

Description

Technical field [0001] The invention relates to a sound insulation board, in particular to a composite sound insulation board and a production process thereof. Background technique [0002] A sound insulation board refers to a board with an average sound insulation (a piece of infinite material is placed between the sound source and the measured point in an infinite space) that exceeds 30dB. General objects have a sound insulation effect, and sound insulation boards are generally high-density materials. According to the classification of civil engineering, it can be divided into two types: sound insulation of buildings and sound insulation of structures. [0003] Most of the sound insulation boards used in architectural decoration are made of cement, which have the disadvantages of heavy weight, poor sound insulation effect, and poor insulation effect. Some building materials using gypsum board as sound insulation boards have low strength, strong water absorption, and impact resis...
