Research on sound insulation performance of lightweight composite wood door based on vertical corrugated structure
摘要
Abstract
In this study,a vertical corrugated wood door core filling material was developed,composite boards of diffe-rent structures were made from the material,and the sound insulation performances of the composite boards were tested and compared according to relevant standards.Then the material was used in the core filling of wood doors to compare and the sound insulation performances of the door leaf and the entire door were verified.This study was aimed at achie-ving the wide application of vertical corrugated board in the core layer filling of composite wooden doors with the goal of creating lightweight sound-insulating composite wooden doors.Additionally,it was expected to provide more compre-hensive and systematic data reference and technical support for the mass production of wooden doors.The results showed that,in the sound insulation test of composite panels,the weighted sound insulation of vertical corrugated composite panels was 0.6 dB higher than that of bridge-hole mechanic composite panels and 3.4 dB higher than that of honeycomb composite panels,proving the feasibility of its use as a core layer filler for sound-insulated wooden doors.The sound in-sulation performance can be improved by 0.6 dB through adjusting the arrangement form of the corrugated layers of the vertical corrugated composite panels,and can improve the sound insulation performance by 2.6 dB by replacing the ma-terials of the core interlayer.The results showed that there was a room for improvement in the sound insulation perfor-mance of vertical corrugated composite panels.In the sound insulation test of the door leaf,the sound insulation performance of the wooden door filled with double-layer vertical corrugated panels was 2 dB higher than that of the wooden door filled with the mechanical board of the bridge.In the sound insulation test of the door as a whole,the sound insulation performance of the wooden door filled with double-layer vertical corrugated panels was 1 dB higher than that of the wooden door filled with the mechanical board of the bridge,demonstrating that the core of the wooden door filled with the vertical corrugated structure has good sound insulation performance.关键词
