Abstract

The invention relates to a sun-shading fabric and a preparation method thereof, in particular to a halogen-free flame-retardant sun-shading fabric with a self-cleaning function and a preparation method of the sun-shading fabric, and belongs to the technical field of high polymer materials. The sun-shading fabric comprises fiber threads forming a double-warp and double-weft structure, the structurecomprises rectangular or square gaps, and the fiber threads are made from a halogen-free polyolefin composite material, wherein the halogen-free polyolefin composite material is prepared from, by weight, 50-70 parts of linear low-density polyethylene, 15-20 parts of an ethylene-vinyl acetate copolymer, 20-30 parts of a halogen-free flame retardant, 3-5 parts of expansible graphite, 1-5 parts of aflame-retardant synergist, 10-20 parts of a flow modifier, 1-3 parts of polyvinylidene fluoride, 1-3 parts of nanometer titania, 3-8 parts of a compatilizer and 2-5 parts of other auxiliaries. The sun-shading fabric has highly flame-retardant and self-cleaning functions.

Description

technical field [0001] The invention relates to a sunshade fabric, in particular to a halogen-free, flame-retardant and self-cleaning sunshade fabric and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] The sunshade fabric is a kind of fabric obtained by covering yarn (the fiber thread obtained by covering the surface of polyester fiber, polypropylene fiber, glass fiber, etc. with polymer plastic) or directly using various fiber threads through weaving. Most of the covered yarn fabrics. At present, most of the fiber threads used in traditional sunshade fabrics on the market are polyvinyl chloride (PVC) coated polyester fibers, which are mainly used in the building sunshade industry. PVC is a widely used general-purpose high-halogen polymer plastic with excellent processing performance. Its high halogen content makes it have good flame retardant performance, but its harm to the environment is also huge: haloge...
