Abstract
The present invention relates to an environmental protection cable wire coating composition which comprises 100 parts by weight of base material polymer, 100 to 200 parts by weight of flame retardant, 1 to 4 parts by weight of antioxidant, 1 to 5 parts by weight of processing agent, and 5 to 20 parts by weight of polyethylene (PE) modifier, wherein the base material polymer is a composition of ethylene-vinyl acetate copolymer (eva) and low-density polyethylene (LDPE), and the polyethylene (PE) modifier is a graft polymer formed by grafting maleic anhydride on polyethylene.
Description
Technical field
The relevant a kind of cable wire coating composition of the present invention refers to a kind of environmental protection cable wire coating composition especially.
Background technology
Cable is widely used in power line, connection and optical fiber cable etc., and its flame resistivity influences the security of superelevation building, rapid transit, market, office block etc.In case cable is impaired because of fire, then the take refuge required fume exhaust system of escape, warning system, reporting chain etc. can't operate, and not only influence is escaped and also is unfavorable for the disaster rescue.Therefore, the material that lining is used outside the cable must be particular about flame resistivity especially.
The outer lining of existing cable is mainly with polyvinyl chloride (PVC, polyvinyl chloride) be base material, can disengage chlorion or spirit of salt etc. during owing to the PVC material combustion, it can catch the free radical that causes fire spread, reach the effect that suppresses chain reaction, so can slow down fire spread.Yet, not only produce dioxin poison gases such as (Dioxin) during the PVC material combustion, also can produce a large amount of black smokes and corrosive gases, the dense smoke that the scene of fire produces hinders take refuge escape and rescue work to carry out, corrosive gases can make the people suffer from pulmonary edema even death after sucking, simultaneously also corrode machinery equipment, cause greatest property damage.
In order to improve the problem that the PVC material combusting is caused, develop at present with polyolefin resin, polyethylene, polypropylene or its co-polymer (ethene-vinyl acetate polymkeric substance for example, (ethylene-vinyl acetatecopolymer is to call the EVA resin in the following text) is the cable serving of base material.Yet, these materials itself have combustibility, therefore must additionally add flame retardant to reach anti-combustion effect, because flame retardant is inorganic particle mostly, and substrate polymer is an organism, the consumption of inorganic particle very high (be generally substrate polymer 0.5 to 2 times), inorganic particle is difficult for being scattered in the substrate polymer, so the adulterant that is generated is heterogeneity phase (heterogeneity), when moulding, easily produce hole, cause the physical strength of cable serving to descend.The general way of compatibility that improves is for to carry out surface treatment with inorganic flame retardant with compounds such as stearic acid or oleic acid, with the dispersiveness that improves incombustible agent (referring to United States Patent (USP) the 4th, 671, No. 896), though this kind mode can solve inorganic particle and the not good problem of substrate polymer compatibility, its shortcoming is that required stearic acid or oleic processing cost are quite high.
Therefore, the invention provides a kind of environmental protection cable wire coating composition, to solve above-mentioned shortcoming.
Summary of the invention
The purpose of this invention is to provide a kind of environmental protection cable wire coating composition, the amount of being fuming during its burning is low far beyond the PVC plastics.
Another object of the present invention provides a kind of environmental protection cable wire coating composition, does not produce dioxin (Dioxin) and corrosive gases during its burning, to ensure HUMAN HEALTH and property device security.
Another purpose of the present invention provides a kind of environmental protection cable wire coating composition, and it has callable characteristic, to meet environmental benefit.
A further object of the present invention provides a kind of environmental protection cable wire coating composition, and it not only can guarantee safety and environmental protection, and does not damage the physical properties of made product.
Another object of the present invention provides a kind of environmental protection cable wire coating composition, and it can promote compatible and escapable cost between inorganic particle and the substrate polymer.
For achieving the above object, environmental protection cable wire coating composition of the present invention, it comprises:
A) substrate polymer of 100 weight parts, it is the mixture of ethylene-vinyl acetate copolymer (EVA) and new LDPE (film grade) (LDPE);
B) flame retardant of 100 to 200 weight parts;
C) antioxidant of 1 to 4 weight part;
D) silicone oil of 1 to 5 weight part, Microcrystalline Wax or stearate; And
E) polyethylene of 5 to 20 weight parts (PE) modification agent, it is the graftomer of maleic anhydride graft on polyethylene.
Embodiment
According to environmental protection cable wire coating composition of the present invention, mainly comprise following five kinds of compositions.
Composition A
Composition A according to the present invention is substrate polymer (Base Polymer), it comprise ethylene-vinyl acetate copolymer (Ethylene-vinylacetate copolymer, EVA) and new LDPE (film grade) (LDPE).
Consumption with composition A is a benchmark, and EVA accounts for 40 to 90 weight %, and is preferably 60 to 80 weight %.
(melting index MI) is preferably between 0.5 to 10 gram/10 minutes the melting coefficient of LDPE, is more preferred between 1 to 5 gram/10 minutes.The melting coefficient of EVA is preferably between 0.5 to 10 gram/10 minutes, and the best is between 1 to 5 gram/10 minutes.
The content of the acetic ester among the EVA (vinyl acetate) is preferably 18 to 33 weight %, is more preferred from 20 to 30 weight %.
Composition B
Composition B according to the present invention is inorganic flame retardant.Utilizing inorganic flame retardant retarded combustion is that the present technique field is familiar with.The inorganic combustion inhibitor of composition B according to the invention is preferably W 4600 (Al (OH)
33H
2O) or hydronium(ion) oxidation magnesium etc., these hydrated things at high temperature thermal endothermic decomposition are oxide compound and water vapour, and the fire extinguishing effect that can reach cooling and suffocate also can discharge positively charged ion simultaneously, can suppress the free radical that combustion processes produces, so that slow down chain reaction.
Composition C
Composition C according to the present invention is an antioxidant, its function series is in order to slow down the macromolecular material automatic oxidation rate, and the condition of selecting for use is to have good oxidation-resistance, good with the macromolecular material compatibility, stable under processing temperature (with other auxiliary agent reaction, nondiscoloration), nontoxicity, do not influence high molecular other characteristic.The antioxidant that is fit to is for example phenols (for example comprising single phenol, polyphenol, Resorcinol, thiobisphenol) used always of present technique field, amine (pentanoic, Ursol D), thioesters class and composition thereof.

Comparison sheet three and table four, can find that the amount of being fuming, poison gas and dioxin (Dioxin) content that the made cable wire coating of environmental protection cable wire coating composition of the present invention is produced is low far beyond adopting the made person of PVC base material when combustion test, oxygen index value and burning gas potential of hydrogen are then higher, therefore cable wire coating tool returnability uses the made cable wire coating of constituent of the present invention to have environmental protection and security concurrently simultaneously.
Quite high with required stearic acid of the inorganic flame retardant of surface treatment or oleic processing cost in the prior art, and in the environmental protection cable wire coating composition of the present invention, substrate polymer with 100 weight parts is a benchmark, only need the PE modification agent of 5 to 20 weight parts, and its cost only is about surface-treated 50%.In addition, the elongation of the cable wire coating that constituent of the present invention is made and tensile strength also show quite high level, and susceptible of proof PE modification agent can effectively be promoted the compatibility of base material polymerization and inorganic flame retardant.
