High-temperature-resistant polypropylene woven bag and preparation method thereof

The invention discloses a high-temperature-resistant polypropylene woven bag which is prepared from the following raw materials in parts by mass: 150-160 parts of polypropylene particles, 20-25 parts of glass fibers, 3-5 parts of nano titanium dioxide, 2-4 parts of polyethylene wax, 5-7 parts of ceramic fibers, 2 parts of an ultraviolet light absorber, 1 part of an antioxidant, 1 part of a coupling agent and 0.5 part of turpentine. According to the woven bag, the ceramic fibers and the glass fibers are added into the raw materials, so that the high-temperature resistance of the woven bag body is greatly improved, the nano titanium dioxide has ultraviolet resistance and antibacterial performance, the weather resistance of the woven bag is greatly improved, and the polyethylene wax can improve the high-temperature resistance of the whole polypropylene mixed raw material; the high temperature resistance of the woven bag is improved to 150 DEG C or above, so that the woven bag meets the use requirement in a parti
