Abstract
The present invention relates to a flat fibre flame retardant rope of polyhydrocarbonlon, which belongs to protective articles for enhancing the safety of freight trains. The rope is prepared from the raw materials of the following weight percentage: 20% of polyethylene, 80% of polypropylene, BDDP with the dosage accounting for 3% of the total dosage of polyethylene and polypropylene, and diantimony trioxide with the dosage accounting for 2% of the total dosage of polyethylene and polypropylene according to the following methods: mixing and stirring the polyethylene and the polypropylene; adding the BDDP and the diantimony trioxide to the mixture; making the new mixture enter a drawbench through a feed hopper, and heating; cooling threads drawn by the drawbench by a cooling water tank and successively stretching the cooled threads into an oven by a primary draw machine; stretching the thread from the oven by a secondary draw machine to obtain qualified threads; finally, obtaining the flame retardant rope by threading twisting, rope combining and rope releasing. The rope has the characteristics of fire resistance, abrasion resistance, strong pulling force, etc. and is mainly used for fire prevention and fire retardant of freight trains.
Description
Technical field
The present invention relates to a kind of flat-fibre flame-retardant rope of polyhydrocarbonlon, belong to the protective articles technical field, be applied to the goods train protection.
Background technology
Be the protection goods, the compartment of existing goods train is provided with fire-retardant paulin mostly and carries out lid, with common rope (net) harness, is blown up to prevent paulin on fire-retardant paulin, and up, down train are produced potential safety hazard.But, this common rope (net) poor fire, during in train operation or in marshalling yard, fire line is poor.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this invention is to provide a kind of flat-fibre flame-retardant rope of polyhydrocarbonlon, to improve the security of goods train.
Technical scheme of the present invention is: this flat-fibre flame-retardant rope of polyhydrocarbonlon, it is characterized in that, by following weight percentages, make as follows: raw material is, the consumption of polyethylene 20%, polypropylene 80%, eight bromo ether is 3% of relative polyethylene and a polypropylene consumption sum, and the consumption of antimonous oxide is 2% of polyethylene and a polypropylene consumption sum; With polyethylene mix with polypropylene stir after, add eight bromo ether and antimonous oxide, enter in the wire drawing machine by feed hopper and to heat, the silk thread that is drawn by wire drawing machine cools off through the cooling water water tank, stretch through the one-level hauling machine and enter baking oven, the silk thread that is come out by baking oven stretches through the secondary hauling machine, gets satisfactory silk thread, after twist thread, close rope, put rope, this flame-retardant rope.
Described wire drawing machine is five thermals treatment zone, and 1 district is the end of heating for heating head end, 5 districts; 1 district's heating-up temperature is 140 ℃, and 2 districts are 160 ℃, and 3 districts are 250 ℃, and 4 districts are 500 ℃, and 5 districts are 600 ℃;
The water temperature of described water tank is controlled to be 40 ℃;
The rotating speed of described one-level hauling machine roller is 800 rev/mins, and the roller rotating speed of secondary hauling machine is 1200 rev/mins;
Described temperature of oven is 400 ℃.
The invention has the beneficial effects as follows: have characteristics such as anti-flammability, ABRASION RESISTANCE, pulling force be big.The main application fire protection flame retarding.
The rupture pull force of flame-retardant rope is not less than 1.5KN, and the percentage elongation during 80% rupture pull force is not more than 15%.
Rope has fire resistance, all is not more than its afterflame, ignitor firing time 10S.
The anti-wear performance of rope: rope per minute on frictional testing machine rubs 60 times, and friction 30min does not rupture.
Description of drawings
Accompanying drawing is a production technology block diagram of the present invention.
The specific embodiment
As figure, the flow sheet of flame-retardant rope: batching-wire drawing-cool off-draw-toast-draw-twist thread-the close rope-packing of restricting-put.
Raw material (percentage by weight): the consumption of polyethylene 20%, polypropylene 80%, eight bromo ether is 3% of relative polyethylene and a polypropylene consumption sum, and the consumption of antimonous oxide is 2% of polyethylene and a polypropylene consumption sum.
With polyethylene mix with polypropylene stir after, add eight bromo ether and antimonous oxide, enter in the wire drawing machine by feed hopper and to heat, the silk thread that is drawn by wire drawing machine cools off through the cooling water water tank, stretch through the one-level hauling machine and enter baking oven, the silk thread that is come out by baking oven stretches through the secondary hauling machine, gets satisfactory silk thread, after twist thread, close rope, put rope, this flame-retardant rope.Twist thread, close rope, to put operations such as rope same as the prior art.
Wire drawing machine is five thermals treatment zone, and 1 district is the end of heating for heating head end, 5 districts; 1 district's heating-up temperature is 140 ℃, and 2 districts are 160 ℃, and 3 districts are 250 ℃, and 4 districts are 500 ℃, and 5 districts are 600 ℃.The water temperature of water tank is controlled to be 40 ℃.The rotating speed of one-level hauling machine roller is 800 rev/mins, and the roller rotating speed of secondary hauling machine is 1200 rev/mins.Temperature of oven is 400 ℃.
Said temperature parameter and rotary speed parameter value all can in ± 5% scope.
The diameter of flame-retardant rope is 3 (± 0.3) millimeters.
The rupture pull force of net muscle and tether is not less than 1.5KN, and the percentage elongation during 80% rupture pull force is not more than 15%.
Rope has fire resistance, and its afterflame, duration of fire resistance all are not more than 10S.
The anti-wear performance of rope: rope per minute on frictional testing machine rubs 60 times, and friction 30min does not rupture.
