Description

High strength thick wall special-shaped ethylene profile and production method thereof
Technical field
The present invention relates to a kind of high strength thick wall special-shaped ethylene profile and production method thereof, belong to the technical field of ethylene profile technical recipe and production method thereof.
Background technology
After last century, the fifties Frenchman invented the PVC section bar, last century, the nineties China domestic enterprise just began large-scale production and sale.And even product develops into foam PVC section bar by original PVC section bar and has developed thick wall special-shaped ethylene profile synchronously.Because of the facility investment of foam section bar is big, subsidiary material composition corrodibility is big in its prescription, to equipment mould seriously corroded, and also easily aging, supporting power is little, and therefore poor toughness is not adopted by enterprise.So Development and Production is a kind of have high strength, anti-aging, supporting power is big, good toughness, it is promising important that the special-shaped ethylene profile that production cost is low shows.
Summary of the invention
A kind of high strength thick wall special-shaped ethylene profile and production method thereof have been the object of the present invention is to provide.That the present invention has is anti-aging, hardness is high, good toughness, supporting power is big, colour-fast, non-corrosibility strong, waterproof, fire-retardant, advantage such as the secondary re-workability is strong, and precision and glossiness height, easy for installation, greatly reduces production cost.
In order to achieve the above object, technical scheme of the present invention is:
A kind of high strength thick wall special-shaped ethylene profile, formulated by the component of following weight per-cent: high density polyethylene(HDPE) 20～25%, carbon black 38～46%, clorafin 4～11%, zinc borate 10～18%, silane coupling agent 4～8%.
Described compositions in weight percentage preparation is preferably: high density polyethylene(HDPE) 24%, carbon black 45%, clorafin 9%, zinc borate 16%, silane coupling agent 6%.
Described silane coupling agent adopts the chain alkyl Trimethoxy silane.
High density polyethylene(HDPE) (HDPE) is a kind of TPO that is generated by ethylene copolymer, and HDPE is a kind of degree of crystallinity height, nonpolar thermoplastic resin.The milky appearance of ortho states HDPE is to a certain degree translucent in meagre cross section.Have the good anti-great majority life and the characteristic of chemicals for industrial use.This polymkeric substance is non-hygroscopic and have a good steam-preventing.HDPE also has good electrical property.
Carbon black is exactly a carbon simple substance, and chemical formula is exactly C " under the normal temperature, the chemical property torpescence of carbon, carbon is subjected to sun exposure or contacts with air, moisture, all is difficult for changing ".Atomic structure of carbon, outermost electron number have 4 just, in the chemical reaction at normal temperatures, are not easy to lose outermost 4 electronics, also are not easy to obtain 4 electronics and become a kind of rock steady structure.Here it is at normal temperatures, the inactive reason of the chemical property of carbon.People have the outermost electron of atom the atomic structure of 4 electronics usually, are called " semi-stability structure ", have the simple substance of the element of semi-stability structure, and at normal temperatures, chemical property is torpescence all generally.Anything all has relativity, and carbon is no exception.At high temperature, it is lively that the chemical property of carbon just becomes, and can follow many material generation chemical reactions.Physical properties: black powder shape solid.Chemical property has: 1, burning promptly has combustibility 2, with reactive metal oxide reductibility is arranged promptly in oxygen.
Clorafin, chemical name: C 24H 44C 16, be the aqueous or arborescens product of a kind of water white or yellow thickness (solid generally all grinding powder), water insoluble, do not fire, not quick-fried, nontoxic, non-volatile, can be dissolved in many solvents.Have better fire-retardant persistence, and have protection against the tide, antistatic, anti-softening, incompressible, low volatility concurrently; Fire-retardant, electrical insulating property is good, and lubricated and anti-skidding characteristics are arranged, and toughness reinforcing tackify and radiation resistance are arranged, and waterproof, insect protected and corrosion proof function are arranged.
Zinc borate is random white or pale yellow powder, and water insoluble, ethanol, propyl carbinol, benzene are soluble in sulfuric acid, methyl-sulphoxide, and Heat stability is good easily disperses, and is nontoxic.
It is long chain silane coupling agent HD-1 that silane coupling agent adopts the chain alkyl Trimethoxy silane, molecular formula: CnH 2n+1Si (OCH 3) 3N=7～12; Outward appearance is colourless to pale yellow transparent liquid, content 〉=90.0%, and density is 0.8870～0.8910 (p 20) g/cm 3Refractive index is 1.3000 ± 0.0050 (n 2D 5), boiling point is 117～121 ℃/1.7mmHg.This product is soluble in the general organic agent such as hydrocarbon, ether, ketone, and facile hydrolysis, condensation form polysiloxane.
The production method of described high strength thick wall special-shaped ethylene profile runs up 30～50 minutes for being placed on after at first each component being prepared by above-mentioned weight percent in the mixing machine, then mixed each component is put in the barrel of twin screw extruder, open twin screw extruder, engine speed is that per minute 0.6～1 changes, each component is transmitted simultaneously by screw rod, in extrusion die, form blank, setting head temperature is 150～170 ℃, and extrude, extrusion temperature is 165～180 ℃, again through the stock mould plastotype, and last inlet chest cooling, cooling temperature is 10～15 ℃, is high strength thick wall special-shaped ethylene profile after the cooling.
The time of running up is preferably 40 minutes in the described mixing machine, and head temperature is preferably 160 ℃, and extrusion temperature is preferably 170 ℃, and cooling temperature is preferably 12 ℃.
Beneficial effect of the present invention is: high strength thick wall special-shaped ethylene profile of the present invention, have anti-aging, hardness is high, good toughness, supporting power are big, colour-fast, non-corrosibility is strong, waterproof, fire-retardant, advantage such as the secondary re-workability is strong, and precision and glossiness height, easy for installation, greatly reduce production cost.
