Abstract
The invention belongs to the flame-proof cable material technical field, be specifically related to a kind of cable PP Pipe Compound and preparation method thereof, it is characterized by and comprise following component (weight part): basic resin 40-60 part with fire retardation; Fire retardant 20-30 part; Oxidation inhibitor 0.1-0.5 part; Dispersion agent 5-10 part; Coupling agent 0.5-5 part; Lubricant 0.1-0.5 part.Said fire retardant is the mixture of micro encapsulation red phosphorus, white lake and Marinco H, and white lake and Marinco H order number are more than-10000.The good flame retardation effect of product of the present invention, and kept good processing characteristics and mechanical property.
Description
Technical field:
The present invention the invention belongs to the flame-proof cable material technical field, is specifically related to a kind of cable that prevents and prolongs the fire retarding material for cable of combustion.
Background technology:
The fire-retardant problem of electric wire is various countries' question of common concern always, and cable generally is bunchy or many installations and lays that the insulation of cable and sheath are made up of combustible superpolymer mostly.Therefore, in case burning, because the interaction between cable makes flame prolong combustion, fire enlarges rapidly, and the people's life and property brought about great losses.
Existing cable waterproof technology roughly can be divided into two types.One type is to take fire prevention to arrange to common cable to revolve, and for example, to common cable coated waterproof paint, fills fire-retardant material etc. at the communicating pores position of raceway.Another kind of is fire-retardantization of being devoted to cable itself; Producing various cables that can fire-retardant propagation of flames when fire burns, the fire-retardant usefulness of normal cable all be inorganic fire-retarded fillers such as white lake or Marinco H, improved the density of CABLE MATERIALS so to a great extent; When having improved deadweight; Improved the processing request of product, because white lake easy tap under the situation of processing temperature, the product flame retardant properties of making can reduce to a great extent.
Summary of the invention:
The object of the present invention is to provide a kind of density little, processing request is low, the flame retardant cable that flame retardant properties is good.
For realizing the object of the invention, technical scheme of the present invention is:
A kind of fire retarding material for cable, form by the component of following each weight part:
Among the present invention, said basic resin is ethylene-vinyl acetate copolymer (EVA), and ethylene-vinyl acetate copolymer (EVA) can hold more fire retardant, and flame retardant effect is better.
Said fire retardant is the mixture of micro encapsulation red phosphorus, white lake and Marinco H; Wherein micro encapsulation red phosphorus accounts for 70~75% (massfractions) of fire retardant; White lake accounts for 20~25% (massfractions) of fire retardant, and Marinco H accounts for 1~5% (massfraction) of fire retardant.Red phosphorus, white lake and Marinco H respectively have the fire-retardant mechanism of oneself, and three's logotype can be brought into play synergy.Wherein said micro encapsulation red phosphorus has overcome red phosphorus and collective's resinous polymer consistency is poor, be prone to shortcomings such as the moisture absorption and oxidation, and the point of ignition that makes red phosphorus is brought up to 320 ℃ by original 240~250 ℃; Said white lake and Marinco H order number are more than-10000.
Said oxidation inhibitor is 4,4 '-thiobis (the 6-tertiary butyl-3-methylphenol), tris phosphite, a kind of or at least a mixture in four (β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid) pentaerythritol ester.
Said dispersion agent is a kind of or at least a mixture of triethyl hexyl phosphoric acid, sodium lauryl sulphate, methyl amyl alcohol, derivatived cellulose, SEPIGEL 305, guar gum, fatty acid polyglycol ester.
Said coupling agent is the organic chromium complex compound, silane coupling agent, titanate coupling agent, zirconium class coupling agent, one or more in magnesium class coupling agent and the tin class coupling agent.
Said lubricant is a white oil.White oil can lower the frictional coefficient of red phosphorus and material and container and Mixing Machine; Guarantee the operational safety of stir mixing; (general earlier PE; Pellet such as PP and white oil mix earlier, this material and red phosphorus combustion inhibitor low speed (100-200r/min) such as " little red " are mixed again, and successively other material or auxiliary agent are expected to mix therewith again).The thermal conductivity of red phosphorus is merely about 1% of metal, so if do not add white oil, be again high-speed stirring, because of fricative heat accumulate the burning-point that (heat radiation is difficult) reach red phosphorus very soon the red phosphorus pyrophoricity accident takes place; 2) the wetting PE of white oil, can be stained with fine powder above that when fine powder mixes pellet such as PP and " little red ", and this can make the flame retardant resistance of flame retardant products even; 3) white oil can be eliminated the dust of red phosphorus combustion inhibitor, further guarantees production safety; 4) white oil still is a kind of external lubricant and brightening agent, impels and extrudes or inject carrying out smoothly of processing, and make product appearance better.
The flame retardant cable preparation method for material special that proposes among the present invention is: with basic resin is that ethylene-vinyl acetate copolymer (EVA) mixes earlier with white oil; Again low speed (100-200r/min) such as fire retardants such as this material and micro encapsulation red phosphorus, oxidation inhibitor, dispersion agent, coupling agent are mixed; Use the twin screw extruder extruding pelletization again, obtain blend composition.Again blend composition is placed thick framed of 1mm, (180 ℃ of upper and lower mould temperature) preheating 6min on moulding press, the pressure hot pressing 4min with 5.0M Pa colds pressing to normal temperature with 10.0M Pa again, the dry acquisition.
The invention has the beneficial effects as follows:
1, ethene-vinyl acetate vinegar multipolymer (EVA) can hold more fire retardant, good flame retardation effect.
2, be that fire retardant is effective with micro encapsulation red phosphorus, white lake and Marinco H, cost is low.
3, product good mechanical property can not reduce its flame retardant properties when formed product, after adding coupling agent and dispersion agent, fire retardant can be good at combining with basic resin.
Embodiment:
Below in conjunction with specific embodiment the present invention is described further.
