Problems solved by technology

[0002] With the rapid development of the rope industry, its application range covers various fields. In climbing training occasions, people often use both hands to directly pull the rope body up and down. This climbing method basically relies on human hands for up and down movements. Because the rope surface in the prior art is all smooth, such climbing rope obviously cannot carry out this kind of action on a large scale and for a long time, especially when climbing a large slope, these shortcomings just seem to be more prominent. The risk factor of climbing is greatly increased, and the expansion rate of some ropes is not enough to make the climber cause sports injuries to himself due to the large force in an emergency

Embodiment 1

[0015] The present invention carries out according to the following steps:

[0016] 1) Melt the PET, then add hydroxylic acid ester to it first, so that the hydroxylic acid ester is evenly dispersed in the PET melt, and then stand still for 10-30min;

[0017] 2) Then inject zinc stearate into the above molten liquid, inject zinc stearate into the molten liquid from the upper part and the lower part respectively, form convection, make it evenly disperse in the molten liquid, and then let it stand for 20 minutes;

[0018] 3) Configure reinforcing fluid, which is made of high-strength high-modulus polyethylene and wear-resistant masterbatch;

[0019] 4) Inject the enhancement liquid into the liquid formed in 2), and inject it from the upper part and the lower part separately to make it evenly dispersed, and let it stand for 18 minutes.

[0020] The added amount of the hydroxylic acid ester is 6% of the type of PET melt.

[0021] The zinc stearate add-on is 6% of the PET melt ty...

Embodiment 2

[0025] The present invention carries out according to the following steps:

[0026] 1) Melt the PET, then add hydroxylate to it first, so that the hydroxylate is evenly dispersed in the PET melt, and then stand for 25 minutes;

[0027] 2) Then inject zinc stearate into the above molten liquid, inject zinc stearate into the molten liquid from the upper part and the lower part respectively, form convection, make it evenly disperse in the molten liquid, and then let it stand for 15 minutes;

[0028] 3) Configure reinforcing fluid, which is made of high-strength high-modulus polyethylene and wear-resistant masterbatch;

[0029] 4) Inject the enhanced liquid into the liquid formed in 2), and inject it from the upper part and the lower part separately to make it evenly dispersed, and let it stand for 20 minutes.

[0030] The added amount of the hydroxylic acid ester is 5% of the type of PET melt.

[0031] The zinc stearate add-on is 8% of the PET melt type.

[0032] The injection...

Abstract

The invention relates to a preparation technology of a wear resistant and tensile rope. Through improvement of the technological preparation method and selection of materials, the invention enhances the mechanical properties of the rock climbing rope and greatly increases the wear resistance of the rope. The production process enables uniform dispersion of the raw materials and comprehensive distribution of the rope performance, and does not cause obvious weak point, greatly improves the safety performance of the rope, and achieves very good technical effects after actual use.
