Abstract
The invention discloses manufacture method of a kind of hermetic collar with flame-retarding characteristic and products thereof.The composition of this product comprises neoprene, magnesium oxide, zinc oxide, precipitated calcium carbonate, carbon black, age resistor, promoter, stearic acid, process oil.This cutting ferrule uses at cabinet cable import and export, and the isolation flammable explosive gas is arranged, the effect of protection cable.Can be applicable in the cabinet of oil, chemical system.
Description
The invention discloses a kind of hermetic collar manufacture method and product with fire resistance, it belongs to technology and the application of electrical engineering with rubber plastic spare.
Up to the present in the electric equipment, import and export, be all no sealing device such as cables such as switch cubicle, distribution boards.This is the hidden danger that fire and explosion accident take place for oil, chemical system.In a single day petrochemical system, flammable explosive gas are revealed in the space, fill the air in power distribution station and cable trench, tend to scurry in the electric devices such as switch cubicle, distribution board along the cable import and export.The electric arc of opening, being produced when breaking of electric switch is very easily ignited these gases, causes heavy economic losses and human casualty accident.
This cutting ferrule is applicable to the import and export of petrochemical system high and low pressure switch cubicle cable and other local cable discrepancy place.The sealing cable is imported and exported, and can stop flammable explosive gas effectively.In case fire takes place, cutting ferrule can also stop further spreading of the condition of a disaster, the scope that the minimizing accident takes place.
The stock of this cutting ferrule can add an amount of fire retardant and other auxiliary agent by thermoplastics or rubber and make.Material component used in the present invention is by weight: 100 parts of neoprenes; 5～20 parts of chlorinated paraffin waxs; Sb
2O
32～5 parts; 1～5 part in magnesium oxide; 1～5 part in zinc oxide; 20～80 parts of precipitated calcium carbonates; 10～50 parts of carbon blacks; 5～25 parts of stearic acid; Process oil is an amount of.
The manufacturing of cutting ferrule is, after at first neoprene and other auxiliary agent being weighed up according to quantity, carries out low temperature and open refining in mill.To open the refining neoprene earlier when opening refining, then promoter, age resistor, fire retardant, vulcanizing agent, precipitated calcium carbonate be added.Carbon black adds wherein behind the process oil dipping again.Sizing material is opened refining and is finished, and is cut into adhesive tape by specification, and the mould of packing into vulcanizes on vulcanizing press at last.Curing temperature is greatly about 150～160 ℃, 6～10 minutes time.
This cutting ferrule profile, similar garden platform or turriform.On the cutting ferrule specialized designs groove, for closely contacting, support the usefulness of cutting ferrule with panel.The cutting ferrule inner surface is smooth, and outer surface is the garden ring-type of projection, and its effect one is thinner at the wall of ring junction, garden, is easy to cutting during construction, so that cutting ferrule adapts to the cable of different size; Be intensity and elasticity in addition, it can be cooperated with panel and cable better, play good sealing function in order to increase cutting ferrule.
This cutting ferrule can also be protected cable effectively, is unlikely because of mechanical external force makes cable to sustain damage at import and export, has both made cable because of extraneous factor breakage take place, and relies on the insulation of cutting ferrule, also is unlikely punch-through over the ground to occur, thereby guarantees equipment safety operation.
The best design that this fire retardant hermetic collar is formed is by weight:
100 parts of A, neoprenes
10 parts of B, chlorinated paraffin waxs
C, Sb
2O
35 parts
4 parts in D, magnesium oxide
5 parts in E, zinc oxide
60 parts of F, precipitated calcium carbonates
35 parts of G, carbon blacks
2 parts of H, promoter
2 parts in I, age resistor
10 parts of J, stearic acid
K, process oil are an amount of
This fire retardant hermetic collar, ageing-resistant, oil resistant, anti-ozone and flame resistance are good, flexible.Fire resistance, oxygen index are greater than 30.
