Embodiment
Describe in the face of the preferred specific embodiment of the present invention down:
In the present embodiment, the main raw material of this low smoke and zero halogen optical cable flame-retardant sheath material is Vilaterm (PE), fire retardant, coupling agent, tenderizer, plastics brightening agent, lubricant, inhibitor, carbon black, each component material therefor and ratio such as following table:
Each component effect is explained respectively as follows:
(1) base-material: MDPE;
(2) fire retardant: white lake and Marinco H;
metal hydroxidess (hydrated metal oxygenant) fire retardant mainly is meant white lake and Marinco H.White lake is hibbsite, and (being called for short ATH) is main inorganic metal oxyhydroxide fire retardant, accounts for more than 80% of inorganic combustion inhibitor consumption, and after ATH was heated, three crystal water can discharge under three different temperature.The fire retardant mechanism of ATH can reduce: one: fill the density loss that ATH can make flammable superpolymer; Two; ATH heat absorption back dehydration, aquation is water vapour absorbing polymeric burning institute liberated heat, and the temperature that suppresses polymkeric substance raises, and the concentration of dilution inflammable gas and oxygen stops combustion reactions to be proceeded; Three: can generate the Al2O3 thermofin on the combustiblematerials surface after the ATH dehydration, stop polymkeric substance to contact, play fire retardation with oxygen.The flame retardant effect of ATH and its addition have very big relation, and generally needing just can have obvious effects more than 50%.So big addition can make the viscosity of plastics increase, and plasticity reduces, and elongation at break descends.In order to address this problem, generally adopt coupling agent treatment ATH, can obtain effect preferably.The granularity of ATH has very big influence to polymkeric substance flame retardant properties and mechanical property, and research shows, the fire retardant of equivalent; Granularity is more little, and specific surface area is big more, and flame retardant effect is good more; The ATH of ultra-fine granularity can strengthen the interaction at interface, effectively improves the mechanical property of multipolymer.Metallic hydrogen Natural manganese dioxide (MH) also is a kind of effective halogen-free flame retardants, and its principle is similar with white lake.Show according to research, adopt magnesium hydroxide flame retardant polyolefine oxygen index can reach 41.The research that with the Marinco H is halogen-free flame retardants is a lot, all obtains effect preferably, and flame retardant of magnesium hydroxide and white lake are similar, also are high additive flame retardant, and for this reason, it is necessary that Marinco H has been carried out various surface treatments.Use a kind of fire retardant generally to be difficult to satisfy the request for utilization of non-halogen flame-retardant cable separately, therefore, usually select for use two or more fire retardant to be used.
are used ATH and Marinco H, can play synergy, though the heat of Marinco H decomposition and absorption is littler than white lake, decomposition temperature is higher, can reach 340 ℃.Marinco H has the polymer surfaces of promotion to become the charcoal effect.Both are used in combination and make flame retardant effect better.
(3) coupling agent: titanic acid ester TC-2 is being a base-material with polyolefine such as PE, does not contain with hydrated aluminum oxide etc. in the protecting sleeve of optical cable of dry flame retardant filler of free-water, adopts monoalkoxy type titante coupling agent comparatively effective;
(4) tenderizer: A6006 is exclusively used in and adds the PE product, and it can increase the snappiness of PE, rebound resilience property, the winter hardiness of increase PE, subduing property;
(5) plastics brightening agent: the modification amide waxe, it has good inside and outside lubricity and surface-brightening property; Good mutual fusibleness and non-stick property; Filler had good dispersiveness; Can improve the vividness and the luminance brightness of sheath material; Has HMP and low viscous peculiar property and good transport property in molten mass;
(6) lubricant: the PE wax lubricant, superpolymer after fusion, have higher viscosity usually, in the course of processing; The fused superpolymer is when extruding, and during through spiral shell thorax and mold runner, polymer melt must produce friction with the processor surface; Some friction is very disadvantageous to the processing of polymkeric substance; These frictions reduce fluidity of molten, and serious friction simultaneously can make jacket surface become coarse, lack gloss or flow liner occurs.For this reason, needing to add to improve oilness, to reduce friction, reduce the interface adhesion property is the purpose auxiliary agent.Here it is lubricant.Lubricant can also play fusion promotor, anti and effects such as antistatic agent, slipping agent except improving flowability.Lubricant can be divided into two kinds of external lubricant and internal lubricants, and the effect of external lubricant mainly is the friction that improves the hot metal surface of polymer melt and processing units.It and polymer phase capacitive are relatively poor, easily in the melt toward external migration, so can form lubricated thin layer at the interface of plastic melt and metal.Internal lubricant and polymkeric substance have good consistency, and it plays the effect that reduces force of cohesion between polymer molecule in polymkeric substance inside, thereby improve the living heat of internal friction of plastic melt and the flowability of melt.External lubricant commonly used is Triple Pressed Stearic Acid and its esters; Internal lubricant is low-molecular-weight polymkeric substance.The lubricant that polyolefins is commonly used has HSt, CaSt, ZnSt, erucicamide, high boiling point paraffin, the right wax of crystallite, PE wax etc.The present invention adopts the PE wax lubricant, is because it and PE base-material homogeneity have better consistency;
(7) oxidation inhibitor: antioxidant 1010 and inhibitor 168, in order to thermo oxidative aging.Adopt 1010 phenols (four [β-(3, the 5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester) oxidation inhibitor as primary antioxidant, 168 phosphorous acid esters (three ［ 2.4-di-tert-butyl-phenyl ］ phosphorous acid ester) oxidation inhibitor is as collaborative oxidation inhibitor.The former can absorb the radical that oxidizing reaction produces, latter's chain reaction then capable of blocking, the carrying out of inhibited oxidation process;
(8) carbon black: channel black, in order to ageing resistance by ultraviolet light, granularity is 15-30nm.Adding base-material with the carbon black master batch form mixes.
the foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this; Can not limit protection scope of the present invention with this, all equivalences that spirit is done according to the present invention change or modification all should be encompassed within protection scope of the present invention.
