High-strength and wear-proof PP plastic rope

Abstract

The invention discloses a high-strength and wear-proof PP plastic rope. The high-strength and wear-proof PP plastic rope is prepared from raw materials by weight: 110-140 parts of modified polypropylene, 5-8 parts of dimethyl phthalate, 6-8 parts of trimethyl ethyl acetate, 15-22 parts of filler, 0.5-1.2 parts of plasticizer, 1.5-3 parts of paroline and 0.5-1 part of lubricant. The polypropylene is modified, organosilicone and rigid functional group naphthalene rings are introduced in a bound manner, specifically, firstly, propylene monomers are pre-polymerized in an emulsion polymerization manner, then a modifier is added, double bonds on the modifier and the propylene are co-polymerized and then embedded into the polypropylene, the polypropylene with the organosilicone is obtained, due to introduction of the organosilicone, on one hand, the unit density of polypropylene chain segments is improved, the mechanical strength of the polypropylene is greatly improved, the bearing stress isenhanced, then the wear-proof performance of the PP rope is improved, and due to introduction of the rigid functional group naphthalene rings, the mechanical strength of the polypropylene is furtherimproved.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to a high-strength and wear-resistant PP plastic rope. Background technique [0002] Most of the plastic ropes on the market now use polypropylene (PP) as the raw material, 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, stiffnes...

AI Technical Summary

Problems solved by technology

In traditional wear-resistant plastics, relevant wear-resistant additives are added to the polypropylene matrix to improve the wear resistance of plastic filaments. However, a large amount of wear-resistant additives can achieve a good wear-resistant effect. However, this large amount of additives Addition will greatly reduce the mechanical properties and flexibility of the plastic body
