Problems solved by technology

[0004] At present, most of the sound-absorbing panels used on roads are wooden sound-absorbing panels. Wooden sound-absorbing panels are composed of facings, core materials and sound-absorbing thin felts. They come from a wide range of sources, but they have the disadvantages of low flame retardancy and poor corrosion resistance.

Abstract

The invention discloses a highway composite acoustic panel material and a preparation method thereof, and relates to the field of acoustic panels. The highway composite acoustic panel material is prepared from the following raw materials in parts by weight: 20-30 parts of waste polypropylene plastic particles, 8-15 parts of polypropylene, 8-15 parts of vinyl-vinyl acetate copolymer, 6-12 parts ofglass bead, 15-20 parts of expanded perlite, 5-10 parts of mica powder, 4-8 parts of fiberglass, 3-6 parts of nano titanium dioxide, 3-6 parts of nano silicon nitride, 10-18 parts of lignocellulose, 3-5 parts of hydroxymethyl cellulose, 2.5-3.6 parts of silane coupling agent, 1.8-3.5 parts of antioxidant and 2.8-4.2 parts of flame retardant. The acoustic panel material is prepared by taking the waste polypropylene plastic particles as a main raw material, the waste is recycled, the production cost is low, the material is excellent in flame resistance, corrosion resistance, water resistance andsound insulation property, and the preparation method is simple.

Description

technical field [0001] The invention relates to the field of sound-absorbing panels, in particular to a composite sound-absorbing panel material for roads and a preparation method thereof. Background technique [0002] Urban noise seriously affects the normal life and personal health of urban residents. Urban noise mainly refers to traffic noise, factory noise, construction noise and social life noise. It has become one of the conspicuous urban environmental pollution problems. The most direct harm of noise to the human body is hearing damage. When people enter a strong noise environment and are exposed for a period of time, they will feel uncomfortable in both ears, and even have headaches and other sensations. [0003] The noise on the road includes the sound of motor vehicle horns and engines, as well as the sound of surrounding construction. Due to the rapid increase in the number of motor vehicles, traffic noise has become the main noise source in cities. The usual ...
