Description
Technical field
The present invention relates to PE coil pipe field of material technology, specially a kind of preparation method of uvioresistant PE coil pipe material.
Background technique
PE coil pipe is widely used in the sides such as field irrigation, gas conveying as the term suggests being the PE tubing of coiling together
Face, it has the characteristics that installation is simple and convenient, low in cost, recycling is convenient, flexibility is good and abrasive resistance is strong.And PE coil pipe is certainly
Uniqueness physicochemical property possessed by body depends primarily on PE coil pipe material.
And in existing PE coil pipe material, that there are oxidation resistances is weak, flexing when fatigue strength it is low, and do not have
Anti-ultraviolet ability.If being exposed under violent illumination condition for a long time, PE coil pipe material can be made gradually to change colour, become
It is crisp；Simultaneously in the long-term use process, corrosion and decomposing phenomenon easily occurs, and then influences normal service life；And in flexing
When, easily cracked and zone of fracture, load performance are poor.
In view of the above problems, therefore, it is necessary for designing a kind of preparation method of uvioresistant PE coil pipe material.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of uvioresistant PE coil pipe material, by modified antioxidant
Existing triphosphite ester and 2,4-DTBP both with antioxidative substance, and two kinds of substances can play
Synergistic effect, first is that by the living radical generated in capture degradation process, to prevent or inhibit chain initiation reaction and chain from increasing
Long reaction, so that free chain reaction is terminated, second is that by generated peroxide after decomposition further degradation, and generate
Stable nonactive product interrupts chain reaction to prevent oxidation process from continuing, thus achieve the effect that 1+1 is greater than 2, with
Exempt from the long-term use process, influences normal service life because corrosion occurs with decomposing phenomenon, greatly improve the PE disk
The oxidation resistance of tube material；
In the present invention in drawing and setting processing, by cross section and the similar non-individual body of Oral incision in the same direction into
The hyposynchronous opposite stretched operation of row three, and tractive force each time and draw-down rate are all the same, stretching ratio each time and
Draft temperature shows a increasing trend, and then makes the macromolecular chain of its inside, segment axially and circumferential orderly arrangement, significantly
The degree of orientation of cross section Yu the similar non-individual body of Oral incision is improved, so that the fatigue when tensile strength and flexing of product is strong
Degree greatly increases in the orientation direction, in case during flexing, cracked and zone of fracture, and influence the pressure-bearing property of product
Energy；
According to the peculiar structure of ESCALOL 567 in the present invention, hydroxyl hydrogen on phenyl ring and adjacent
Between ketonic oxygen, intramolecular hydrogen bond can be formed and constitute chelate ring, after absorbing ultraviolet light, thermal vibration, hydrogen bond quilt occur for molecule
It destroys so that chelate ring is opened, compound is in unstable upper state at this time, stablizes shape being restored to original low energy
During state, extra energy is released, thus high energy, harmful ultraviolet light become low energy, harmless thermal energy, in order to avoid when long
Between be exposed under violent illumination condition so that the PE coil pipe material gradually changes colour, becomes fragile, substantially increase anti-ultraviolet
