Problems solved by technology

Metal sound insulation materials are not only expensive, but because of their relatively weak rigidity, their sound insulation performance is not ideal, and their anti-corrosion performance cannot meet the requirements of use.
[0003] Cement fiber sound insulation board is a board made of wood fiber mixed with inorganic hydraulic cementitious materials such as cement and sand, which is pressurized. Because it contains wood fiber, it has poor waterproof performance and can only be used in dry indoor environments. If it is wet, its sound insulation performance will be greatly reduced, and its appearance quality is not good, generally it cannot be used directly as an exterior wall
And the cement-based gelling material will form micropores when it is evaporated and solidified. The existence of micropores not only reduces the waterproofness of the cement fiber sound insulation board, but also affects its sound insulation.

preparation example Construction

[0035] The preparation method of the particle sound insulation board comprises the following steps:

[0036] (1) Stir and mix the binder pre-added with the coupling agent and the particles of different particle sizes separately, and place it for 0.2-0.5 hours; the particle composition is 40-45 parts of φ0.8mm particles, 40-45 parts of φ0.4mm particles Parts, 3.5-7 parts of φ0.2mm particles, 7-14 parts of φ0.1mm particles; the amount of binder added is 4-6% by weight of particles, and the amount of coupling agent added is 1% by weight of binder -5%; the binder is selected from epoxy resins, phenolic resins, urea-formaldehyde resins and furfuryl alcohol resins, and the coupling agent is selected from silane coupling agents and coupling agents containing isobutyl functional groups.

[0037] (2) Lay a layer of φ0.8mm particle vibration compaction in the mold;

[0038] (3) Lay two layers of φ0.4mm particle vibration compaction in the mold of step (2);

[0039](4) Add φ0.2mm parti...

Embodiment 1

[0044] Examples 1, 2, and 6 were prepared by uniformly mixing the particles once, and Examples 3-5 were prepared by the preparation method of the present invention.

[0045] 2. After testing, the sound insulation and water resistance of the above-mentioned embodiments are shown in the following table:

[0046]

[0047] Therefore, it can be seen from the above table that the particle sound insulation volume of the particle sound insulation board prepared by the method of the present invention meets the requirements of the sound insulation board, and has excellent sound insulation performance, waterproof and anti-corrosion properties. Compared with Example 6 of the particle voids, not only the amount of binder used is greatly reduced, the production cost is reduced, but also the sound insulation is improved. Compared with Examples 1 and 2, which adopt the preparation method of one-time uniform mixing, the sound insulation board prepared by the preparation method of the presen...

Abstract

The invention discloses a micro-particle sound-insulating plate. Micro-particles are adopted as a substrate for the sound-insulating plate and the micro-particle sound-insulating plate comprises a skeleton and a filling material, wherein gaps of the skeleton are filled with the filling material; and the skeleton is formed by binding skeleton micro-particles and the filling material comprises filling micro-particles, a binder and a coupling agent. The micro-particle sound-insulating plate has the advantages of good sound absorption performance as well as good corrosion and water resistance, can be directly used as external walls and meanwhile, since the sound-insulating plate has the color of the micro-particles, the requirement of customers on aesthetic feeling of the appearance of the sound-insulating plate can be met by combining micro-particles with different colors. In addition, the invention also discloses a preparation method of the sound-insulating plate through compaction by jolting in layer-by-layer and step-by-step manners, through the preparation method, gaps among the micro-particles are staggered, small-sized micro-particles are added in some times so that small-sized micro-particles enter the gaps among large-sized micro-particles so as to achieve filling effect and ensure that the micro-particle sound-insulating plate is dense and seamless.

Description

technical field [0001] The invention relates to a sound insulation and noise reduction engineering material, in particular to a particle sound insulation board and a preparation method thereof. Background technique [0002] Noise pollution in modern society has become a major problem of environmental pollution, and sound insulation panels are the most commonly used products in noise control projects. Sound insulation board, as the name suggests, refers to a board that can isolate, isolate and separate the noise transmitted in the air. Generally speaking, materials with a certain quality have a certain sound insulation performance, and the sound insulation board should weaken the transmitted sound energy and block the transmission of sound. big weight. Metal materials (such as steel, aluminum, etc.) and non-metal materials (such as cement sound insulation boards, etc.) are generally used as sound insulation materials in noise reduction projects, but there are many problems ...
