The first and second mentioned in this application are only for describing different parts, and do not indicate their sequence order; the Z twist direction and the S twist direction are merely two opposite twist directions, and if the first strand is Z twist direction, the second strand is S twist direction.
In some embodiments, the high-strength casting umbrella rope with the anti-burning and micro-buffering functions is formed by weaving a plurality of S-lay-direction first strands and a same number of Z-lay-direction second strands; the first rope strand is formed by twisting a plurality of ultra-high molecular weight polyethylene fiber filaments, and the fineness of the first rope strand is 1500-3000D; and the first strand is treated with a scorch retarder; the second rope strand is formed by twisting a plurality of aramid 1414 fiber filaments, and the fineness of the second rope strand is 1000-3000D; the anti-burning agent comprises 15-30% of silicone oil, 5-10% of adhesive, 5-12% of penetrating agent and the balance of water, wherein the percentage content is mass percent.
As an alternative, the number of first strands is set to 2, 3, 4, 6, 8 or 12.
As an alternative, the number of second strands is set to 2, 3, 4, 6, 8 or 12.
In an alternative embodiment, the number of the ultra-high molecular weight polyethylene fiber filaments is set to 1 to 3, and the twist is 30 to 110 twists/m.
As an optional embodiment, the number of the aramid 1414 fiber filaments is set to be 2-4, and the twisting twist is 30-110 twists/m.
Generally, the silicone oil has good heat resistance, weather resistance and hydrophobicity and smaller surface tension, and after the strands of the ultrahigh molecular weight polyethylene fiber are treated by the anti-scorching agent containing the silicone oil, the anti-scorching performance of the ultrahigh molecular weight polyethylene fiber umbrella rope is effectively enhanced by the excellent physical and chemical properties of the anti-scorching agent.
Further alternatively, the silicone oil may be modified to have better anti-scorching properties, such as dimethyl silicone oil, carboxyl-modified silicone oil, polyether-modified silicone oil, amino-modified silicone oil, and epoxy-modified silicone oil.
The amino modified silicone oil is polydimethylsiloxane containing amino in a side chain or a terminal group, has good adsorbability and compatibility, and can increase the softness of the fiber material when the amino silicone oil is emulsified into microemulsion by a proper surfactant.
The epoxy modified silicone oil is silicone oil containing epoxy in the side chain or end group of polydimethylsiloxane, and can improve the elasticity of the fiber rope, and if the silicone oil is matched with polyether modified silicone oil for use, the flexibility of the fiber rope after finishing is better.
The polyether-modified silicone oil is polydimethylsiloxane having a polyether group (e.g., polyoxyethylene group, polyoxypropylene group, fatty alcohol polyoxyethylene polyoxypropylene ether group) in a side chain or a terminal group, and can improve moisture absorption performance of post-finishing of a fiber rope. The introduction of the polyether group also increases the antistatic property and easy decontamination property of the finished fiber or fiber rope, can prevent static accumulation and prevent static from generating electric sparks.
The shuttle-modified silicone oil is polydimethylsiloxane containing a shuttle group in a side chain or a terminal group, can improve durability, and particularly has better effect when being used together with amino silicone oil.
The dimethyl silicone oil is a colorless and transparent novel synthetic polymer material, and has special smoothness, flexibility, hydrophobicity, good chemical stability, excellent electrical insulation property and high and low temperature resistance. The anti-burning performance of the ultra-high molecular weight polyethylene fiber rope can be effectively improved.
As an alternative embodiment, the silicone oil is a silicone oil microcapsule. The silicone oil is prepared into the silicone oil microcapsules, the silicone oil can be sealed in the microcapsule shell to prevent volatilization, the influence of moisture absorption on the performance of the microcapsule shell is reduced, the capsule shell is broken under the action of external forces such as mutual friction and collision of the umbrella rope and the umbrella coat in the use process of the microcapsule, the silicone oil sealed in the capsule shell is leaked out, the anti-burning effect of the microcapsule can be exerted, and the storage life and the service life of the umbrella rope are prolonged. For example, the umbrella rope can be treated by preparing a silicone oil microcapsule emulsion with a shell layer of silicon dioxide, and preparing the emulsion with a binder, a penetrating agent and water into an anti-burning agent according to a certain proportion. Silicone oil/silicon dioxide microcapsules are adhered to the surface of the treated rope fiber; for example, polyurea coated dimethicone nanocapsules can be prepared as the silicone oil component of the antipyrotic; for example, calcium alginate coats silicone microcapsules as the silicone oil component of the antipyrotic.
As an alternative embodiment, the modified silicone oil can be prepared into a microcapsule form for use.
In an alternative embodiment, the particle size of the microcapsules is set to 50 to 150 nm. Further as an optional embodiment, the nano-microcapsule with the particle size of 100-150 nm is selected. Further as an optional embodiment, the nano-microcapsule with the particle size of 50-100 nm is selected.
Further, as an alternative embodiment, a proper amount of nano carbon material, such as at least one of nano modified graphite, nano carbon black or graphene, can be added into the anti-burning agent, so that the heat conduction and the electric conduction performance of the fiber rope are increased, the surface friction resistance of the fiber rope is reduced, static electricity is prevented, the anti-burning performance and the durability of the fiber rope are improved, and the service life is prolonged. In an alternative embodiment, the amount of the nanocarbon material is set to 3 to 8% by mass.
As an alternative embodiment, anionic penetrants may be chosen as penetrants, e.g. RCOO-, -SO3ˉ、-OSO3ˉ、-PhSO3ˉ、-OPO3-a-component; as an alternative embodiment, a non-ionic surfactant, such as a polyoxyethylene ether surfactant, may be selected.
As an alternative embodiment, ethyl acetate or the like may be selected as the binder.
Further, in some embodiments, the outer surface of the high-strength parachute cord is coated with a layer of anti-burn agent. After the first strand of the throwing umbrella rope is treated by the anti-burning agent, the anti-burning agent covers the surface of the ultra-high molecular weight polyethylene fiber, so that the throwing umbrella rope has a certain anti-burning function, after the first strand and the second strand are woven into the umbrella rope, the surface of the umbrella rope is usually in direct contact with other umbrella ropes, umbrella covers and the like in the using process, the friction and collision and other effects occur, the damage to the surface of the umbrella rope is more serious, and therefore, the anti-burning agent can be coated on the outer surface of the throwing umbrella rope, so that the anti-burning capacity of the surface of the umbrella rope is improved.
