The invention adopts magnesium hydroxide and aluminum hydroxide of the halogen free flame retardant, and avoids the use of a halogenous flame retardant, thereby not only effectively improving the flame retardant property of the cable material, but also ensuring that the cable material has better mechanical property.
Description
Technical field
The present invention relates to the cable in a kind of cable technology field, especially relate to a kind of low-smoke halogen-free combustion-preventing cable insulation and sheath material and manufacture method thereof.
Background technology
Flame-proof cable sheath material belongs to a kind of matrix material, and it normally is equipped with suitable weighting agent by matrix resin forms, and requires also should have the comparison excellent flame-retardant except having higher physical and mechanical properties.Superpolymer itself does not generally have fire retardancy, and the flame retardant properties method commonly used that improves polymer materials is additive flame retardant to be filled into prepare flame-proof composite material in the polymer materials.Fire retardant commonly used has: halogen-containing compounds, phosphorous compounds, hydrated metal oxide and zinc borate compounds.
Red phosphorus is a kind of fire retarding synergist the most efficiently of hydrated metal oxide.At present, there is the efficient synergy of utilizing red phosphorus and hydrated metal oxide to reach the method for flame retardant effect.Yet chemical reaction slowly can take place with air in red phosphorus in a humid environment, produces the phosphuret-(t)ed hydrogen (PH of severe toxicity
3) gas, and red phosphorus dust explosive, can so that lead to disaster because of the high heat spontaneous combustion in inside when storing in a large number.For this reason, red phosphorus must could use safely and effectively through surface treatment.In addition, the inherent red-purple of red phosphorus own has limited the application of phosphorous CABLE MATERIALS greatly.And the fire-resistant cable material that contains red phosphorus all can be emitted irritating smell during in process of production with burning in large quantities.
Hydrated metal oxide belongs to hydrate and hydrate and the formed double salt of other element or the compound of the metallic element oxide compound of IA family in the periodic table of elements, II A family, group III A, IVA family and IVB family.Prepare flame-proof composite material with hydrated metal oxide (normally magnesium hydroxide and aluminium hydroxide) as fire retardant, can avoid because the variety of problems that interpolation halogen or red phosphorus based flame retardant cause.No matter which kind of conventional superpolymer matrix resin is, measure the flame retardant properties of flame-proof composite material with testing vertical flammability, when the addition of magnesium hydroxide or aluminium hydroxide had only 60% (mass percent) of surpassing, matrix material vertical combustion grade just can reach the FV-0 grade.A large amount of fillings of magnesium hydroxide or aluminium hydroxide will inevitably greatly reduce every physicals of matrix material.So, not adopting special technique, matrix material is difficult to take into account simultaneously to have high mechanical property and excellent flame-retardant.
Because the hydrated metal oxide surface energy is than higher, with surface energy polymer difference great disparity.When being adopted as through the hydrated metal oxide of surface modification,, can produce the uneven phenomenon of dispersion because of the poor compatibility of inorganic particulate and polymkeric substance with the matrix resin blend.The physical and mechanical properties of matrix material will show and reducing.So, hydrated metal oxide is carried out surface modification, introduce organic group on its surface, improve and polymkeric substance between compatibility, thereby improved the dispersive ability of hydrated metal oxide, and then improved every physical and mechanical properties of matrix material.The surface treatment method of hydrated metal oxide is a lot.According to the difference of treatment process, can be divided into wet processing and dry process.Different surface treatment agents is to hydrated metal oxide surface-treated effect difference, because different surface treatment agent molecules has different structures, different with reactive force between hydrated metal oxide or the polymer molecular chain, thus cause the reactive force power that exists between hydrated metal oxide and the polymkeric substance different.
In addition, when matrix resin is polyethylene, need to adopt crosslinked (chemically crosslinked or radiation crosslinking) technology sometimes especially existing the preparation in the method for non-halogen flame-retardant cable, can improve the temperature capacity and the tensile strength of non-halogen flame-retardant cable like this.But this crosslinking process can prolong the production time of product, increases production cost of products, thereby has limited promoting the use of of non-halogen flame-retardant cable.
Summary of the invention
The object of the present invention is to provide a kind of halogen-free flame-proof cable sheath material.Its components in mass portion is represented mainly to comprise:
