Spun-bonded nonwoven fabric capable of adsorbing harmful gases and preparation method thereof



The invention discloses a spun-bonded nonwoven fabric capable of adsorbing harmful gases and a preparation method thereof. The spun-bonded nonwoven fabric is prepared from the following raw materials in parts by weight: 80 to 90 parts of polypropylene, 10 to 20 parts of high adsorption master batch, 1 to 2 parts of coupling agent, 1 to 2 parts of dispersing agent and 0.1 to 0.2 part of antioxidant. The preparation method comprises the steps of: placing various raw materials into a high-speed mixer according to the mass weight, and uniformly mixing and stirring the raw materials to obtain a mixture; placing the mixture into a spun-bonded nonweaving device, melting, extruding, crosswind cooling, stretching by slit airflow, laying, hot rolling and reinforcing. The high adsorption master batch containing synthetic porous calcium silicate is added into the polypropylene spun-bonded nonwoven fabric, so that the prepared nonwoven fabric not only has the advantages of good filter performance, uniformity in laying, stability in gram weight, good surface glossiness and the like, but also has certain adsorption capacity for harmful gases such as formaldehyde, benzene and xylene.
