Abstract
The invention discloses a high-wear-resistance PP rope. The high-wear-resistance PP rope comprises the following raw materials in parts by weight: 100 to 150 parts of modified polypropylene, 15 to 20parts of a filler, 6 to 12 parts of ethylene propylene diene monomer, 0.5 to 1.2 parts of a plasticizer, 0.3 to 0.5 part of an antioxidant, 1.5 to 3 parts of paraffin oil and 0.5 to 1 part of a lubricant. According to the invention, polypropylene is modified, and organic silicon is introduced in a bonding manner. Specifically, an emulsion polymerization mode is adopted; a propylene monomer is pre-polymerized, then a modifier is added, and double bonds on the modifier are copolymerized with propylene so as to be embedded into polypropylene, so the polypropylene containing organic silicon is obtained; and due to introduction of the organic silicon, the unit density of a polypropylene chain segment is increased, the mechanical strength and the flexibility of the polypropylene are greatly improved, and the bearing stress of the polypropylene is enhanced, so the wear resistance of the PP rope is further improved.
Description
technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to a high wear-resistant PP rope. Background technique [0002] Most of the plastic ropes on the market today are based on polypropylene (PP), which has been the fastest growing major thermoplastic, especially in fiber and filament, film extrusion, injection molding processing, etc. Polypropylene's excellent flow properties and wide range of flow rates, combined with other unique polymer properties, give it excellent processability. The lower flow rate can meet the processing requirements of extruded tape, tape filament and monofilament, etc., and can also make the finished product have tensile strength and low elongation, while maintaining sufficient transverse integrity, so that the winding machine guide device The splitting and dusting conditions are kept to a minimum. Main features: non-toxic, odorless, low density, strength, stiffness, hardness and heat resistanc...
