Abstract
The invention discloses a prescription of halogon-free fire retardant steel framework plastic compound pipe material. The halogon-free fire retardant modified plastic for producing steel framework plastic compound pipe is composed of following material by weight: 60-90 shares of HDPE polyethylene, 10-30 shares of superfine zinc borate, 1-5 shares of boracic acid triethanolamine, 0-20 shares of EVA resin and 5-15 shares of ammonium polyphosphate APP. The modified plastic has a good fire retardant characteristic to make the steel framework plastic compound pipe with more broad applications. Meanwhile, the material can be used for other halogon-free fire retardant plastic products. The pipe produced by such material has a good corrosion resistance, heat resistance, stability and a long service life.
Description
Technical field:
The present invention relates to a kind of modified plastics, especially a kind of halogen-free inflaming retarding steel framework plastic composite tube raw material formulation.
Background technology:
Steel skeleton plastic clad pipe is a kind of NEW TYPE OF COMPOSITE pressure tubing.Can be widely used in the gas of industries such as oil, chemical industry, municipal administration, building, agricultural, medicine, the conveying of liquid, be the ideal substitute of common steel tube and galvanized steel pipe, product is widely used in industries such as oil, chemical industry, combustion gas, water supply, blowdown, mining, seawater conveying with its distinctive anticorrosion, wear-resisting, withstand voltage, creep resistance, easy for installation and high cost performance etc.Steel skeleton plastic clad pipe is as a kind of novel metalloid tubing of extensive use, and cost is few, save a large amount of metallic substance, steady performance.
But nearly all plastics are easy firing all, and some of them also can produce a large amount of obnoxious flavour and smog in when burning, and the disaster hidden-trouble that brings has thus become the problem that the whole world is paid close attention to.Need fire-retardant occasion at some, because its combustibility has limited its range of application.Adding effective fire retardant at present is more general method in prevention burning and the technology that produces smog.Fire retardant various in style can be divided into two big classes by chemical composition: i.e. organic fire-retardant and inorganic combustion inhibitor; Can be divided into reactive flame retardant and additive flame retardant by using method.Representative fire retardant is bromine system, phosphorus nitrogen system, phosphorus system and aluminium hydroxide, magnesium hydroxide, antimonous oxide etc.The characteristics of halogenated flame retardant are the flame-retarded efficiency height, and addition is few, and are less relatively to the mechanical property influence of plastic material, therefore are widely used; But the shortcoming that it exists is a large amount of black smoke and the toxic gas of burning generation, and escape and fire extinguishing when being unfavorable for presence of fire produce secondary harm and pollution.Can cause merely the corrosion of the Circuits System switch that can not be caused by fire institute and other metal objects to reach in addition pollutes environment; To the harm of human respiratory tract and other organ even because of the life-threatening safety of suffocating.In recent years, states such as the U.S., Britain, Norway, Australia had formulated or had promulgated a decree, and the use of halogen flame is limited.The exploitation halogen-free flame retardants replaces the development trend that halogen flame has become world's flame retardant area.
Adding inorganic combustion inhibitor is developing direction, what use at present is to add inorganic substance such as aluminium hydroxide, magnesium hydroxide, yet the necessary heavy addition of the flame retardant effect that reaches expection, addition even reach more than 40% ~ 50%, the adding of a large amount of inorganic particles causes great injury to poly mechanical property, processing characteristics, and, increased substantially the cost of modifying material because the big processing difficult forming of add-on will add a large amount of auxiliary agents.
Summary of the invention:
In order to overcome the deficiency in the background technology, the invention provides a kind of halogen-free inflaming retarding steel framework plastic composite tube raw material formulation.This modified plastics has good flame retardant property, makes steel skeleton plastic clad pipe have purposes widely, and these starting material also can be used in other halogen-free fire retardant plastic goods simultaneously.The tubing of making of this material has erosion resistance, thermotolerance, can stablize characteristics such as reaching standard-required and life-span length.
The technical solution adopted in the present invention is: this halogen-free flameproof modified plastics that is used to make steel skeleton plastic clad pipe is made by following raw materials according, following raw materials according by mass percentage: 60～90%HDPE polyethylene, 10～30% superfine zinc borates, 1～5% triethanolamine borate, 0～20%EVA resin and 5～15% polyphosphoric acid amine APP.
Above-mentioned superfine zinc borate average diameter of particles is 30-100nm; The ethylene content 15%～18% of EVA resin.
The present invention has following beneficial effect: this modified plastics has good flame retardant property, makes steel skeleton plastic clad pipe have purposes widely, and these starting material also can be used in other halogen-free fire retardant plastic goods simultaneously.The tubing of making of this material has erosion resistance, thermotolerance, can stablize characteristics such as reaching standard-required and life-span length.The fire-retardant starting material of this modification not only are used to make the starting material of steel skeleton plastic clad pipe, also can be used for making purely moulding pipeline and other is the plastic conduit or the goods of raw material with the polyethylene.Be applicable to transfer oil, Sweet natural gas and various processed oil, and be applied to must fire-retardant occasion, low cigarette, nontoxic advantage are arranged.
