Embodiment Construction

[0026] Such as figure 1 As shown, the paper sound-absorbing panel with loofah as the core material in this embodiment includes a surface layer, a back layer and a core layer that are bonded to each other. The back layer is formed by bonding the bottom corrugated paper 5 and the silica gel layer 4, and the core layer is composed of vertically arranged loofah segments 3, which are filled with a mixture of polylactic acid clathrate and polycarbonate.

[0027] Wherein, the preparation method of the mixture of polylactic acid clathrate and polycarbonate comprises the following steps:

[0028] (1) Compounding of polylactic acid inclusion compound: Dissolve cyclodextrin in dimethyl sulfoxide to obtain the first mixed solution, dissolve polylactic acid in chloroform to obtain the second mixed solution; then mix the first mixed solution with the second mixed solution The two mixtures are mixed and stirred, and suction filtered to obtain a precipitate, which is dried and ground to obta...

Abstract

The invention discloses a paper acoustic panel with loofah sponge as a core and a preparation method. The paper acoustic panel comprises a surface layer, a back layer and a core layer, wherein the surface layer, the back layer and the core layer are adhered to one another; the surface layer is made of surface plate corrugated paper (2) and a diatom ooze coating (1) through bonding; the back layeris made of a bottom plate corrugated paper (5) and a silica gel layer (4) through bonding; the core layer consists of vertically arranged loofah sponge sections (3) through combination; and the loofahsponge sections (3) are filled with a mixture of a polylactic acid inclusion compound and polycarbonate. The paper acoustic panel disclosed by the invention has properties of being good in sound absorption effect, environment-friendly, large in strength, and the like.

Description

technical field [0001] The invention relates to a sound-absorbing board and a preparation method, in particular to a paper sound-absorbing board with loofah pulp as a core material and a preparation method. Background technique [0002] With the development of industrial production, transportation, urban construction, and the increase of population density, the increase of household facilities (audio, air conditioner, television, etc.), environmental noise is becoming more and more serious, and it has become a major public hazard that pollutes the human social environment. Noise not only affects hearing, but also has adverse effects on the human cardiovascular system, nervous system, and endocrine system. [0003] The types of sound-absorbing panels currently on the market include wooden sound-absorbing panels, mineral wool sound-absorbing panels, and fabric sound-absorbing panels. Contents of the invention [0004] Purpose of the invention: The purpose of the invention i...
