Abstract
The invention discloses a wire insulating layer plastic composition which is prepared from the following raw materials in parts by weight: 20-30 parts of PVC (Polyvinyl Chloride) resin, 5-8 parts of boric acid, 3-6 parts of stearic acid, 6-8 parts of magnesium oxide, 5-10 parts of nano calcium carbonate, 2-5 parts of starch, 3-7 parts of antioxidant and 10-20 parts of oxidized polyvinyl ester. The wire insulating layer plastic composition is high in tensile strength which can be 12 MPA (Mean Pulmonary Arterial Pressure), and high in application temperature, so that the composition can be applied to wires of 105 DEG C, and moreover as the optioned halogen fire retardant is environment-friendly without biphenyl compound, no dioxin which is harmful to living creatures is emitted when the composition is combusted.
Description
Technical field
The invention belongs to insulating plastics technical field, relate in particular to a kind of electric wire insulation layer plastics composite.
Background technology
At present electric wire is widely used in the transmission of energy and information, and the insulation layer of the electric wire made from traditional macromolecular material or sheath are in use easy to, because circuit thermal value is excessive or short circuit etc. is former thereby burn, cause fire.And limit heavy metal, biphenyl compound etc. in electrical equipment, wire type product in many regions such as European Union, the U.S..It is because meeting discharges dioxin, harmful to biology when traditional halogen flame burns.Therefore environment amenable electric wire will be a kind of development trend.Tradition halogen and antimony are compound system.Inorganic fire-retarded system, common is magnesium hydroxide.The problem of this system is, flame retarding efficiency is low, and addition is large, and Strength retention is low.Phosphorus, nitrogen compound system.This system is not suitable in non-polar material.The problem existing is, resistance to separating out, poor heat resistance.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is, provides that a kind of tensile strength is high, high temperature resistant, can not discharge the electric wire insulation layer plastics composite to the harmful dioxin of biology during burning.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of electric wire insulation layer plastics composite, it is characterized in that, by the raw material of following weight part, made: polyvinyl chloride resin 20-30 part, boric acid 5-8 part, stearic acid 3-6 part, magnesium oxide 6-8 part, part nano-calcium carbonate 5-10 part, starch 2-5 part, oxidation inhibitor 3-7 part, oxidic polyethylene ester 10-20 part.
Above-mentioned negative ion antibiotic plastics, is characterized in that, by the raw material of following weight part, are made: 25 parts of polyvinyl chloride resins, 7 parts of boric acid, 5 parts of stearic acid, 7 parts, magnesium oxide, 7 parts of part nano-calcium carbonates, 4 parts of starch, 5 parts, oxidation inhibitor, 15 parts of oxidic polyethylene esters.
The advantage of electric wire insulation layer plastics composite of the present invention is: tensile strength of the present invention is higher, can reach 12MPA, and use temperature is higher, can be used as 105 ℃ of lines and uses.And the halogen flame of selecting is environment-friendly type,, containing biphenol compound, during burning, can not discharge the harmful dioxin of biology.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
An electric wire insulation layer plastics composite, is characterized in that, by the raw material of following weight part, is made: polyvinyl chloride resin 20-30 part, boric acid 5-8 part, stearic acid 3-6 part, magnesium oxide 6-8 part, part nano-calcium carbonate 5-10 part, starch 2-5 part, oxidation inhibitor 3-7 part, oxidic polyethylene ester 10-20 part.
The preferred embodiment of the present invention is: a kind of electric wire insulation layer plastics composite, by the raw material of following weight part, made: 25 parts of polyvinyl chloride resins, 7 parts of boric acid, 5 parts of stearic acid, 7 parts, magnesium oxide, 7 parts of part nano-calcium carbonates, 4 parts of starch, 5 parts, oxidation inhibitor, 15 parts of oxidic polyethylene esters.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, change, interpolation or replacement, all should belong to protection scope of the present invention.
