Description
Technical Field
The invention relates to a preparation method of a high-strength inorganic sound insulation board, and belongs to the field of building materials.
Background
With the gradual depth of sustainable development concept, the harm of noise is more and more emphasized, and building, especially urban building, is often subjected to noise interference including traffic noise, industrial noise, crowd noise and the like because of being built nearby noise generating sources such as roads, the most common noise reduction method is to increase the density or thickness of a wall body, but the area and the quality of a single-layer wall body are doubled, the sound insulation amount is only increased by 6dB, the wall body quality is only increased by the thickness or density of the wall body within the bearing allowable range of structural load, and in many cases, the key of building sound insulation falls on selecting and using proper sound insulation materials, and the practice shows that the method is the simplest and effective method.
The sound insulation board is a sound insulation material commonly used in noise control engineering, and is generally divided into three categories of inorganic, metal and organic, wherein the metal sound insulation board is expensive, and is poor in strength due to the fact that the metal sound insulation board is generally thinner, the metal sound insulation board needs to be composited with other materials for use, the organic sound insulation board is made of acrylic materials, the compact surface of the metal sound insulation board is good in sound insulation effect, but the metal sound insulation board can be aged rapidly outdoors, the metal sound insulation board is not suitable for being used as an outer wall material, the inorganic sound insulation board is made of various inorganic materials with different particle sizes through bonding of an adhesive, the cost is low, the sound insulation effect is good, micropores are formed in the surface of the inorganic sound insulation board, the metal sound insulation board has certain sound absorption performance, noise reduction can be achieved through two modes of sound absorption and sound insulation, but when the metal sound insulation board is used as an outer wall material, moisture and rainy and snowy weather can cause the metal sound absorption, strength loss can be caused, and when the metal sound insulation board is used indoors, and the metal sound insulation board is too high in humidity.
In summary, in the inorganic sound insulation board in the prior art, the irregular inorganic particles increase the pores on the surface of the inorganic sound insulation board, so that the inorganic sound insulation board has sound absorption performance, and the inorganic sound insulation board absorbs water in humid weather, so that the strength is reduced.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and the blank plate is sandblasted after being pressed by leaching the raw materials with ionic liquid and compounding rubber, so that the sound insulation plate is finally prepared, and the strength loss of the sound insulation plate in a humid environment is reduced while the sound absorption performance of the sound insulation plate is ensured.
In order to solve the technical problems, the invention adopts the following technical scheme:
the preparation method of the high-strength inorganic sound insulation board comprises the steps of ion liquid leaching, composite rubber, bonding pressing and sand blasting.
The following is a further improvement of the above technical scheme:
crushing perlite into particles with the particle size of 1.8-2.2mm, leaching by using a 1-butyl-3-methylimidazole tetrafluoroborate solution with the temperature of 42-47 ℃ and the leaching dosage per minute accounting for 4.5-5.5 weight percent of the total weight of the 1-butyl-3-methylimidazole tetrafluoroborate solution, washing by ethanol, and drying to obtain the perlite particles treated by the ionic liquid;
