20～50 parts of fire retardants;
2～7 parts of steel fibers;
0.2～2 part of stablizer;
1～3 part of tinting material;
1～4 part of lubricant.
Further be that lubricant is any one perhaps both mixing in polyethylene wax and the paraffin.
Further be that stablizer is calcium zinc stabilizer or compound lead stabilizer.
Further be that steel fiber is a Stainless Steel Fibre.
Further be that tinting material is the rutile titanium white powder.
Further be that coupling agent is a titanate coupling agent.
Further be that fire retardant is a Marinco H.
Another technical problem that will solve of the present invention provides a kind of working method of fire-retardant electromagnetic shielding pvc material.
The present invention also provides a kind of working method of fire-retardant electromagnetic shielding pvc material; Raw material counterweight ratio according to above-mentioned fire-retardant electromagnetic shielding pvc material at first mixes SE, coupling agent, fire retardant, stablizer, tinting material and lubricant; Carry out drying treatment then; At last with said mixture and steel fiber mixing moulding.
Further be that mixing moulding is realized through extrusion moulding.
Another technical problem that will solve of the present invention provides a kind of electrical casing pipe of fire-retardant electromagnetic shielding pvc material.
The electrical casing pipe that provides of the present invention is tubular, and this electrical casing pipe is processed by above-mentioned fire-retardant electromagnetic shielding pvc material.
The invention has the beneficial effects as follows: fire-retardant electromagnetic shielding pvc material provided by the present invention has excellent flame-retardant and capability of electromagnetic shielding; Oxygen index can reach more than 32.7; It is under the condition of 30MHZ～1500MHZ; Shield effectiveness can reach more than the 62dB, can satisfy insulation and electromagnetic shielding needs.Working method according to fire-retardant electromagnetic shielding pvc material provided by the invention can be easily with steel fiber and other material mixing moulding, and this needs existing installation to accomplish.
Embodiment
Below in conjunction with embodiment the present invention is described further.
Coupling agent is any one or more than one the mixing of organic chromium complex compound, silicane, titanate ester and aluminic acid compound.
Fire retardant is any one or more than one the mixing in white lake, Marinco H, monoammonium phosphate, diammonium phosphate, ammonium chloride, boric acid, halogenated flame retardant, phosphate flame retardant, the halogenated phosphate fire retardant.Decomposition and absorption combustionmaterial surface heat takes place to fire retardation in Marinco H (340-490 degree) when being heated; Discharge the oxygen on large quantity of moisture dilution combustion thing surface simultaneously, the activated magnesia that decomposes generation is attached to the combustiblematerials surface and has further stoped incendiary to carry out again.Marinco H not only has no objectionable impurities to produce in whole fire-retardant process; And the product of its decomposition can also absorb obnoxious flavour and smog that polymer burnings such as rubber, plastics are produced in a large number in fire-retardant; Activated magnesia constantly absorbs imperfect combustion fusing residue; Eliminate smog when burning is stopped very soon, stop molten drop, therefore, adopting Marinco H is the preferred mode of the present invention as fire retardant.
Steel fiber is steel fiber, copper fiber, preferably uses Stainless Steel Fibre.
Stablizer is any one or more than one the mixing of compound lead stabilizer, metallic salt, rare earth class stablizer.In the calcium zinc stabilizer and the polyvinyl chloride resin course of processing good dispersiveness, consistency, processing fluidity are arranged, wide adaptability, product surface smooth finish is excellent; Stabilising effect is good, and consumption is few, has multifunctionality; In white goods, whiteness is better than its like product.So preferred calcium zinc stabilizer of the present invention.
Tinting material is inorganic and pigment dyestuff, and particularly the rutile titanium white powder is with the coating that white titanium pigment is made, bright in luster; Opacifying power is high, and strong coloring force is low-consuming; Wide in variety, can play a protective role to the stability of medium, and can strengthen the physical strength and the sticking power of paint film; Prevent crackle, prevent that ultraviolet ray and moisture from seeing through, and prolongs the paint film life-span.
Lubricant is any one or more than one the mixing in Triple Pressed Stearic Acid and ester class thereof, stearates, polyethylene wax, OPE, paraffin, stearic amide, the amine hydroxybenzene.As preferably, the present invention adopts the mixture of polyethylene wax and paraffin, and as lubricant, the chemical property of polyethylene wax is stable, electrical property is good.Compare for PVC and other exterior lubricant, polyethylene wax has stronger internal lubrication effect
The working method of fire-retardant electromagnetic shielding pvc material provided by the invention.Need not when mixing, just steel fiber to be mixed with other raw material; Therefore adopt original mixing equipment can realize mixing; And needn't worry that steel fiber destroys equipment or causes and can't mix, after other raw materials mix are intact, again according to the needs of moulding; Mixed raw materials and steel fiber are added molding device, thereby accomplish moulding.In forcing machine, screw rod can well mix other raw material and steel fiber, and forcing machine itself can this type of moulding the product of band fiber, therefore can successfully produce the product that fire-retardant electromagnetic shielding pvc material is processed.
Electrical casing pipe provided by the invention; Be tubular; Adopt fire-retardant electromagnetic shielding pvc material provided by the present invention to process, it is effective when industries such as communication, IT connect up, to make the threading cover, because steel fiber can increase the intensity of electrical casing pipe; Thereby make electrical casing pipe also have enough intensity possessing under excellent flame-retardant and the capability of electromagnetic shielding condition, thereby can apply to the poorer place of working condition.
