Abstract

The invention discloses a melamine sponge, and relates to the technical field of the melamine sponge. The melamine sponge is prepared by the following steps: (1) preparing an ethanol / ammonia water mixed solution; (2) modifying nano zeolite powder; (3) preparing a basic treatment solution; and (4) melamine sponge treatment. According to the melamine sponge, the internal aperture ratio is as high as99%, and the prepared melamine sponge has a relatively high sound absorption coefficient, which indicates that the prepared melamine sponge has an excellent silencing effect so that the melamine sponge can be applied to the field of sound insulation and plays a great role in reducing sound and noise.

Description

technical field [0001] The invention belongs to the technical field of melamine sponge, in particular to a melamine sponge. Background technique [0002] Melamine sponge has a three-dimensional network structure, its opening rate is as high as 95%, and it has good flame retardancy, that is, it forms a dense coke layer on the surface of the burning body after contacting an open flame to retard combustion, without Smoke, no dripping, no burning, self-extinguishing away from the fire. Because of its stable chemical and cross-linked structure, melamine sponge has excellent chemical stability, safety and environmental protection. [0003] Although the melamine sponge prepared by the prior art has a certain sound-absorbing effect, its sound-absorbing effect is general and cannot meet the needs of some occasions in the market. Contents of the invention [0004] The purpose of this invention is to provide a kind of melamine sponge, to solve the deficiencies in the prior art. ...
