Abstract

The invention discloses sound-absorbing wallpaper base paper and a preparation method thereof, and belongs to the field of wallpaper preparation. The sound-absorbing wallpaper base paper is prepared from the following components in parts by weight: 30-45 parts of wood pulp fibers, 25-40 parts of sea-island fibers, 10-20 parts of latex, 3-10 parts of PVC paste resin, 1-6 parts of a plasticizer, and0.01-1 part of a foaming agent. According to the preparation method provided by the invention, the prepared sound-absorbing wallpaper base paper forms a structure with a soft and rough outer surfacethrough adding the sea-island fibers, coating a PVC foaming material at the outer surface of the base paper, and performing foaming, a large number of pores are formed in the base paper, sound waves enter the pores and are propagated inwards, the sound waves have the friction function with a material to make sound energy converted into heat energy, so that the purpose of absorbing sound is achieved; and the sound-absorbing wallpaper provided by the invention has an average sound absorption coefficient of greater than 0.45, and belongs to sound-absorbing materials with better sound-absorbing effects.

Description

technical field [0001] A sound-absorbing wallpaper base paper and a preparation method thereof belong to the field of wallpaper preparation. Background technique [0002] In today's society, noise pollution is becoming more and more serious, and noise in the living environment has become a major factor affecting people's quality of life, especially residents living in urban areas, who are deeply affected by various machine sounds, horns, and noises from morning to night. Therefore, ensuring the quiet environment in the room has become a major problem to be solved urgently. [0003] In recent years, the wallpaper with sound-absorbing function has been favored and sought after by many people. The wallpaper with sound-absorbing function can reduce the noise in the room and protect people's health. In the prior art, sound-absorbing wallpapers are mostly made of a sound-absorbing layer on the basis of wallpaper base paper, and the sound-absorbing layer is mostly made of sound-ab...
