Embodiment Construction

[0007] The present invention relates to a manufacturing method of an aging-resistant polymer strength rope, which comprises the following steps: step 1, preparing polymer high-modulus HSHM-PE fibers, and processing the HSHM-PE fibers on a braiding machine to form a load-bearing core; step 2 , the aramid fiber is woven on the outer surface of the bearing core by a braiding machine to form an aramid fiber sleeve as a heat-insulating protective sleeve; step 3, inject a PVC layer on the outer surface of the aramid fiber sleeve through an injection molding machine as an anti-aging sleeve, and the injection molding time The temperature is 150-200°C. The aging-resistant polymer strong rope prepared by the present invention includes a load-bearing core, the load-bearing core is HSHM-PE load-bearing core, there is a heat-insulating protective sleeve on the outer coat of the load-bearing core, and the heat-insulated protective sleeve is an aramid sleeve. The jacket of the sleeve has an ...

Abstract

The invention discloses a method for making an aging-proof high molecule strength rope. The method comprises the following steps that: 1. HSHM-PE fibers are prepared, and the HSHM-PE fibers are processed into bearing cores by a knitting machine; 2. aramid fibers are weaved to form aramid sleeves outside the outer surfaces of bearing cores by the knitting machine, which are used as heat insulation protective sleeves; 3. the outer surfaces of aramid sleeves are injected with PVC layers to be used as aging-proof sleeves by an injection machine. The aging-proof high molecule mightiness rope made by the method of the invention can greatly reduce strength loss due to aging so as to prolong the service life.

Description

technical field [0001] The invention relates to a manufacturing method of an aging-resistant polymer strong rope. technical background [0002] At present, the load-bearing part of the polymer strong rope used in the world is directly exposed to harsh environments such as air, sunlight, wind and rain, salt spray, etc., so the strong rope is easy to age over time, and the breaking force drops very quickly, so it is easy to security incident. Contents of the invention [0003] The invention provides a method for making an aging-resistant polymer strong rope. The aging-resistant polymer strong rope produced by the method can greatly improve the strength of the rope body and prolong the service life. [0004] The present invention adopts the following technical solutions: a method for making an aging-resistant polymer strong rope, which includes the following steps: Step 1, preparing HSHM-PE fibers, and processing the HSHM-PE fibers on a braiding machine to form a bearing cor...
