MANUFACTURING METHOD OF ECO-FRIENDLY SOUND INSULATION MATERIAL EXCELLENT IN FLAME RETARDANCY AND SOUND INSULATION

摘要

The present invention relates to a method for manufacturing an eco-friendly sound insulating material having excellent flame retardancy and sound insulation, and more particularly, a first grinding step of pulverizing a high flame retardant rubber-based foam, a second crushing step of pulverizing a high flame retardant polyolefin-based foam; A raw material mixing step of mixing the first pulverized product prepared through the first pulverizing step, the second pulverized product prepared through the second pulverizing step and an adhesive, and the mixture prepared through the raw material mixing step is put into a mold, It consists of a molding step of molding and a cutting step of cutting the molded product formed through the molding step. The method for manufacturing an eco-friendly sound insulation material with excellent flame retardancy and sound insulation through the above process is an environmentally friendly, light weight and excellent sound insulation performance by recycling discarded foam. to provide.
