Abstract

The invention discloses an economic and environment-friendly damping plate with high damping property. The economic and environment-friendly damping plate with high damping property is prepared from the following raw materials: a polyurethane elastomer, coal ash, mica, hydrogenated C5 petroleum resin, glass fiber, carbon black, an anti-aging agent and an antioxidant in a mass ratio of (200-250):(410-500):(400-475):(40-80):(4-10):(20-100):5:5. The economic and environment-friendly damping plate with high damping property has the advantages that materials are well chosen, waste coal ash is adopted as a functional damping filler, a waste material is changed into things of value, environment-friendly polyurethane is adopted for replacing harmful asphalt, energy conservation, emission reduction and ecological environmental protection are realized, production cost is low, period is short, a production technology is scientific, the economic and environment-friendly damping plate with high damping property is convenient to manufacture, and the product has good damping and soundproof effects, high damping coefficient, strong aging resistance, long service life and wide applicability and is beneficial to large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an economical and environment-friendly damping plate with high damping performance and a preparation method thereof. Background technique [0002] Fly ash is one of the largest industrial wastes in my country. At present, the annual slag discharge in China has reached 30 million tons. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing year by year. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to humans and organisms. Therefore, the processing and utilization of fly ash has attracted widespread attention. Therefore, the state focuses on clearly encouraging and supporting policies from the following five aspects, mainly including...
