Abstract
The invention discloses a preparation method of an antibacterial and moisture-proof sound absorbing plate, and belongs to the technical field of decorative materials. Kaolin and montmorillonite whichare used as raw materials have a large specific surface area, a high porosity and a high compressive strength, so that the sound absorbing plate has an excellent sound absorbing effect; lemon peel isused as a raw material, and is crushed, lemon essential oil is extracted from the crushed lemon peel with an ethanol solution, and the lemon essential oil has hydrophobic and moisture-proof properties; ramie fibers used as a raw material are treated with an alkali solution, and then are alkylated with isopropyl alcohol as an alkylating agent; holly leaves are used as a raw material, the holly leaves contain protocatechuic acid and some flavonoids, so the holly leaves have antibacterial and antibiotic effects; and the alkylated ramie fibers, peanut oil and holly leaves are blended and fermented, the peanut oil is decomposed into fatty acids and glycerin, the alkylated ramie fibers and the holly leaves are combined together according to the compatible principle of substances with similar polarity, and the obtained mixture is placed in a mold, and undergoes hot-pressing molding to obtain the antibacterial and moisture-proof sound absorbing plate. The antibacterial and moisture-proof soundabsorbing plate has a broad application prospect.
Description
technical field [0001] The invention discloses a preparation method of an antibacterial, moisture-proof and sound-absorbing panel, which belongs to the technical field of decorative materials. Background technique [0002] Sound-absorbing materials are materials that absorb incident sound energy by virtue of their own porosity, thin-film action or resonance. According to their physical properties and sound-absorbing methods, they can be divided into two categories: porous sound-absorbing materials and resonant sound-absorbing structures. . [0003] The structural feature of porous sound-absorbing materials is that there are a large number of interpenetrating and open micropores inside the material. The principle of sound absorption is that after sound waves enter the pores of the material, the air in the pores and the tiny fibers of the material vibrate, resulting in friction and friction. Viscous resistance, sound energy is converted into heat energy and absorbed. There ar...
