Sound barrier, sound barrier assembly structure and manufacturing method of sound barrier
The invention relates to a sound barrier. A preset angle is formed between a sound insulation part and a sound absorption part, the sound absorption part is located in the sound wave reflection direction of the sound insulation part, and the preset angle is smaller than 90 degrees. The invention also relates to a sound barrier assembly structure. At least two sound barriers are sequentially stacked between two installation stand columns in the height direction, and the two ends of each sound barrier are installed on the corresponding installation stand columns respectively. The invention further relates to a manufacturing method of the sound barrier. The method comprises the steps: preparing a monomer mixture of the sound insulation part in proportion, and enabling the monomer mixture to form a prepolymer, wherein the monomer mixture contains organic acid; adding an initiator and a functional aid into the prepolymer, conducting uniform mixing and defoaming, pouring a formed material into a mold, and presetting a reinforcing rib used for being integrally formed inside the sound insulation part in a cavity of the mold; and performing post-polymerization and demolding to obtain the sound insulation part. According to the sound barrier, the preset angle is formed between the sound insulation part and the sound absorption part, multi-dimensional dissipation can be conducted on noise, the noise reduction effect is good, noise reduction and lighting can be considered at the same time, and a good driving environment is created.
本申请涉及一种声屏障，其隔音部分与吸音部分之间呈预设角度设置，且吸音部分位于隔音部分的声波反射方向上，预设角度小于90°。声屏障组装结构，至少两个声屏障在两个安装立柱之间沿高度方向依次叠放，声屏障的两端分别安装在一安装立柱上。声屏障的制作方法，按比例配置制备隔音部分的单体混合物，单体混合物中含有机酸，并将单体混合物形成预聚体；在预聚体中加入引发剂和功能助剂，混合均匀并脱泡后，倒入模具中，模具的型腔内预置用于一体形成在隔音部分内部的加强筋；后聚合，脱模得到隔音部分。本申请的声屏障的隔音部分与吸音部分之间呈预设角度，可以对噪声进行多维耗散，降噪效果好，并可同时兼顾降噪与采光，营造良好的行车环境。
