Abstract

A rigid polyvinyl chloride sound barrier comprises raw materials of 70-90 parts of polyvinyl chloride, 2-12 parts of anti-impact modifier, 4-14 parts of filler, 6-7 parts of composite stabilizer, 0.5-1 parts of ultraviolet inhibitor, 0.5-2 parts of lubricant and 0.01-2 parts of colorant. The preparation includes adding polychloroethylene into heating blend agitator with low rotate speed, increasing rotate speed, adding anti-impact modifier, filler, composite stabilizer, ultraviolet inhibitor, lubricant, and colorant, mixing, heating to the temperature of 100-140 DEG C., discharging the material to cold blend agitator, decreasing temperature to 50 DEG C., discharging, filtering, delivering to extrusion group, cooling and pressing by plate die to produce special plate for sound barrier, which includes back board, front board and connecting board, punching sound absorption holes on front board with a opening ratio ranging 8-30%, a diameter ranging 1-4 millimeters, assembling to form the sound barrier. The sound barrier is light in weight, easy to process, good in corrosion resistance, low in price, easy to install, great heat durability, reusable, with long life and small workload of maintenance.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a sound insulation barrier made of rigid polyvinyl chloride for preventing noise pollution. Background technique [0002] Today, when noise pollution is serious, the application range of sound insulation barriers is quite wide. At present, there are roughly two types of base materials for sound insulation barriers used: one is made of steel plates, which are expensive and difficult to process, and their Long-term use under natural environmental conditions is prone to rust, heavy maintenance workload, and short service life; the other is made of glass fiber reinforced plastics, which is relatively difficult to process, and it is easy to cause glass fiber breakage when opening holes on it. The section is easily eroded by rainwater, the overall strength of the board is much lower, and the service life is short. Contents of the invention [0003] The main purpose ...
