Chinese patent 02157782.X "High specific gravity sound insulation composite material"; CN1654537A "flame retardant sound insulation felt"; CN101343391A "polymer based metal powder flame retardant sound insulation felt"; CN101735530A "flame retardant sound insulation composite material and sound insulation components "; CN1583864A "Preparation Method of Sound-insulating Damping and Noise-Reducing Sheets for Cars" etc. have announced some polymer-based sound-insulating composite materials, but metal powder and other high-density fillers are generally added to the materials, resulting in a relatively large overall density of the material. The screw wear of the extrusion equipment is serious. At the same time, the stability of the material is closely related to the treatment effect of the metal powder. The treatment of the oxide on the surface of the metal powder is complicated.
In addition, the flame retardant and environmental performance of the material need to be further improved.

Abstract

The invention discloses a multi-layer composite environment-friendly flame retardant sound-insulating coiled product. The multi-layer composite environment-friendly inflaming retardant sound-insulating coiled product is formed by alternately overlaying and compounding a material A and a material B, wherein the material A comprises the following components in part by weight: 100 parts of PVC (Polyvinyl Chloride), 10-25 parts of an environment-friendly plasticizer, 25-50 parts of a filler, 3-10.5 parts of a flame retardant smoke-suppression agent, and 10-17 parts of an accessory ingredient, the material B comprises the following components in part by weight: 100 parts of PVC, 20-45 parts of an environment-friendly plasticizer, 25-45 parts of a filler, 3-10.5 parts of a flame retardant smoke-suppression agent, 0.5-5 parts of a foaming agent and a modifier, and 10-17 parts of an accessory ingredient. The sound-insulating coiled product disclosed by the invention has the advantages of being high in sound-insulation, low in density, flame retardant, non-toxic and environment-friendly, good in flexibility, great in strength, capable of performing dry construction and few in occupied space, and not affecting the indoor decorative effect.

Description

technical field [0001] The invention relates to a sound-insulating and flame-retardant new material and a preparation method, in particular to an environmentally friendly flame-retardant and sound-insulating coil product with a multi-layer superimposed composite structure and a preparation method thereof. Background technique [0002] With the rapid development of China's social economy, the problem of environmental pollution has become an increasingly prominent contradiction in economic development. High-intensity noise harms people's bodies, makes people feel tired, produces negative emotions, and even causes diseases in the nervous system, cardiovascular system, endocrine system, digestive system, and vision. Noise pollution, water pollution, air pollution, and solid waste pollution are regarded as four major environmental problems in the world, which are extremely harmful. Therefore, the prevention and control of noise has become one of the important problems to be solv...
