Embodiment 1

[0071] The sound-absorbing material of the present embodiment is prepared from the following material:

[0072] Microporous ceramics: Microporous ceramics of different particle sizes are used and mixed in different proportions (as shown in Table 1).

[0073]Modified epoxy resin: 1.84kg, titanium dioxide: 3.22kg, inorganic silicon: 2.88kg, flame retardant: 2.54kg, zirconia: 3kg, water-based silica sol: 3.2kg, ethanol: 3.32kg.

[0074] Curing agent: 2.4kg.

[0075] i) put the flame retardant 2.54kg and the inorganic silicon 2.88kg into the reaction tank in turn, heat it to 175 °C, stir for 20 minutes, cool to 26 °C, to obtain the first mixture;

[0076] ii) to step i) to the first mixture obtained by adding titanium dioxide 3.22kg, aqueous silica sol 3.2kg, zirconia 3kg, modified epoxy resin 1.84kg stirred evenly, to give the 2nd mixture;

[0077] iii) The second mixture obtained in step ii) was ground twice by a stick pin sand mill, and then 3.32 kg of ethanol was added and stirred...

Embodiment 2

[0084] Example 2: Screening test for preparing a mixture of sound-absorbing material C

[0085] Using the weight percentage of the raw material shown in Table 2, 7 mixtures C are configured by the following method:

[0086] i) the flame retardant and inorganic silicon are successively put into the reaction tank, heated to 175 ° C, stirred for 20 minutes, cooled to 26 ° C, to obtain the first mixture;

[0087] ii) to step i) the resulting mixture of titanium dioxide, aqueous silica sol, zirconium dioxide, modified epoxy resin stirred evenly, to give the second mixture;

[0088] iii) the second mixture obtained in step ii) was ground twice by a rod pin sand mill, and then ethanol was added and stirred for 20 minutes to give the mixture C.

[0089] The viscosity, adhesion and impact strength of the obtained mixture C sample 1, 2, 3, 4, 5, 6 and 7 are determined, and the determination method is as follows: The determination of dynamic viscosity is carried out in accordance with GB / T97...

Description

Technical field [0001] The present invention relates to the field of sound-absorbing materials, specifically to a sound-absorbing material and a method and use thereof. Background [0002] At present, noise has become a major environmental pollution, the sound environment of buildings has attracted more and more attention and attention, the selection of good sound-absorbing materials for buildings to absorb sound, sound absorption is one of the important technical measures. The existing material commonly used for sound absorption is sound absorbing cotton. Sound-absorbing cotton is a kind of artificial inorganic fiber, which uses natural ores such as quartz sand, limestone and dolomite as the main raw material, and is made of glass with some chemical raw materials such as soda ash and borax. In the preparation process of sound-absorbing cotton, the raw materials in the melted state are blown into flocculent fine fibers by means of external force, and the fibers and fibers are thr...
