Product Description

Silica sol &Colloidal silica

Silica sol is a colloidal solution, odorless and non-toxic. Silica sol is a dispersion of nano-scale silica particles in water or solvent. Since the SiO2 in the silica sol contains a large amount of water and hydroxyl groups, the silica sol can also be expressed as SiO2.nH2O.

Plant fiber-based sound-absorbing materials use plant fibers as raw materials, which have the advantages of being degradable and renewable, and have broad prospects in replacing traditional petroleum-based sound-absorbing materials. However, the relatively fluffy structure of plant fiber-based sound-absorbing materials and the characteristics of raw materials, and the poor mechanical properties and fire resistance of plant fiber-based foam materials restrict their development.
The fiber is modified with silica sol, and the ultra-lightweight, high-strength heat-resistant, recyclable and degradable silica sol-plant fiber Sound-absorbing Material can be quickly prepared through foam forming technology. The amount of sol added has varying degrees of influence on the density, mechanical properties, thermal stability and sound absorption properties of the material.

The silica sol is deposited on the surface of the plant fiber to form an inorganic film, which can effectively delay the heat transfer, so that the final decomposition temperature is prolonged, and the thermal stability of the silica sol-plant fiber sound-absorbing material is improved. Compared with no silica sol, the volume of the silica sol-plant fiber sound-absorbing material is reduced, the internal compactness is improved, and the elastic modulus and yield strength are significantly improved. However, with the increase of the silica sol, the density of the sound-absorbing material Obviously increase, too high addition of silica sol is not conducive to the light weight of sound-absorbing materials.


Benefits of silica sol in the application:
The sound absorption effect of the sound-absorbing material without silica sol is the worst. As the amount of silica sol increases, the sound absorption of the material first increases and then decreases. This is because sound waves enter the sound-absorbing material mainly through diffraction. When the internal porosity is too high, the flow resistance of the sound-absorbing material is small, and the sound wave cannot be attenuated repeatedly inside the sound-absorbing material, and finally the sound absorption is caused by the sound-absorbing material. The effect is not good; and when the internal porosity of the sound-absorbing material is too low, sound waves are more likely to be reflected when they reach the surface of the material and cannot enter the inside of the sound-absorbing material, which reduces the sound-absorbing performance of the sound-absorbing material. The addition of silica sol reduces the porosity of the sound-absorbing material and gradually densifies the interior. Combined with the light-weight application of sound-absorbing materials, the density of the sound-absorbing material should not be too high. By optimizing the amount of silica sol added, the pore structure can be made more compact. The sound absorption performance is optimally balanced.
