摘要： The present application discloses a preparation method of SM non-woven fabrics for roof anti-slip, which belongs to the technical field of roofing materials, comprising preparing spunbond non-woven fabric raw materials, preparing spunbond non-woven fabrics, preparing meltblown non-woven fabric raw materials, preparing primary SM non-woven fabrics, and post-processing; the spunbond non-woven fabric raw materials are prepared by uniformly mixing polypropylene with a low melt flow index, polypropylene with a high melt flow index, sodium alginate, antioxidant 1010, zinc stearate, ultraviolet absorber UV-531, polyvinyl alcohol, reinforcing agent, adhesive agent, and nano titanium dioxide. The present application can avoid the problem that the SM non-woven fabrics cannot be fully bonded together and are easy to delaminate when being combined, can also solve the problem of fabric breakage during high-speed production, and can also improve the wear resistance, strength, and stiffness of SM non-woven fabrics. The prepared SM non-woven fabrics have low production costs, are easy to recycle, and have good environmental performances.
