Abstract
The invention mainly relates to the field of polymer materials, especially relates to a polymer material function master batch, and concretely relates to a low-smoke-and-halogen flame-retardant polyvinyl chloride cable material. The cable material comprises, by mass, 100 parts of polyvinyl chloride, 20 parts of dioctyl phthalate, 20 parts of dioctyl terephthalate, 15 parts of chlorinated paraffin, 4 parts of lead sulfate tribasic, 3 parts of dibasic lead phosphite, 0.5 parts of stearic acid, 0.5 parts of paraffin, 30 parts of calcium carbonate, 5 parts of antimony trioxide, 60 parts of aluminum hydroxide and 5 parts of zinc borate. The cable material adopting the above formula has the advantages of efficient flame retardation, inhibition of the smoke generation, excellent flame retardation performance, and no secondary pollution after combustion.
Description
Technical field
The present invention relates generally to polymeric material field, especially macromolecular material functional master batch, particularly low-smoke low-halogen polyvinyl chloride fire-resistant cable material.
Background technology
PVC CABLE MATERIALS has been widely used in wires and cables industry, and the oxygen index of resin itself is 45, has the feature of high flame retardant material.But while using as the Insulation Material of cable and sheath material, need in polyvinyl chloride resin, add a large amount of Synergist S-421 95 (as softening agent, thermo-stabilizer etc.), its flame retardant properties is declined greatly, oxygen index drops to 24 left and right.Common flame retarding PVC composition for cable, can produce a large amount of black smokes during burning, produces a large amount of poisonous corrosive gasess simultaneously, and human body and apparatus are caused to " secondary harm ".Along with expanding economy, some high-grade, precision and advanced plant and instrument, subway, Highrise buildings, power house etc. have proposed some new requirements to the flame retardant resistance of the PVC electric wire using, PVC electric wire is not only required fire-retardant, and will fall low-smoke and toxic gas content.At present, the main dependence on import of low-smoke halogen-free flame-retardant electric wire and cable material of China, expensive, application is subject to certain restrictions.Along with the fast development of China's economic construction, the raising that safety performance is required, increasing to the demand of low-smoke halogen-free flame-retardant electric wire and cable.
For this problem, we have developed low smoke and low halogen wire cable insulating material, have significantly improved the combustionproperty of common flame retarding PVC composition for cable, greatly reduce the burst size of smoke density and the HCI of material.
Summary of the invention
The object of this invention is to provide a kind of low-smoke low-halogen polyvinyl chloride fire-resistant cable material, the effective allotment by formula, can realize highly effective flame-retardant, suppresses the object of smoke creating.
A kind of low-smoke low-halogen polyvinyl chloride of the present invention fire-resistant cable material, it consists of according to the mass fraction:
Adopt the CABLE MATERIALS of above-mentioned formula, can realize highly effective flame-retardant, suppress the object of smoke creating, flame retardant properties is good, and burning can not produce secondary pollution.
Embodiment
The invention will be further described below.
A kind of low-smoke low-halogen polyvinyl chloride of the present invention fire-resistant cable material, it consists of according to the mass fraction:
Above-mentioned lead sulfate tribasic molecular formula is: 3PbOPbSO4H2O, relative molecular weight is: 990.87.
Above-mentioned dibasic lead phosphite molecular formula is: 2pbO.pbHpO
3.H
2o, relative molecular weight is: 742.57.
In above-mentioned formula, aluminium hydroxide addition is larger, after aluminium hydroxide is heated, can produce kinetics, discharges crystal water, absorbs a large amount of heat, and reduces the temperature of polymer surfaces, slows down or suppresses the burning of superpolymer, and promote charing and press down cigarette.
Being used in conjunction with of zinc borate and antimonous oxide, can make oxygen index improve, and can suppress the generation of smog.
