Abstract
The invention discloses a preparation method for an anti-ageing PE tube. The anti-ageing PE tube is composed of the following raw materials by weight: 95.0 kg-99.0 kg of PE resin, 0.5 kg-2.0 kg of an anti-oxidant, 0.1 kg-1.5 kg of an ultraviolet ray screener, 0.2 kg-0.5 kg of an ultraviolet ray absorber, 0 kg-0.2 kg of a quenching agent, and 0.2 kg-0.8 kg of a radical scavenger. In the anti-ageing system, the additives mutually have good synergic effect, the anti-oxidation property is strong, the volatility is small, and the compatibility with PE resin is good; and the mechanical properties of the material are not influenced, high temperature is resisted, and the thermal stability is good.
Description
Technical field
The present invention relates to a kind of PE tubing preparation method, be specifically related to a kind of preparation method of anti-aging PE tubing.
Background technology
Polyethylene is typical thermoplastics, because PE tubing has nontoxic, tasteless, odorless, good cold-resistant, thermotolerance and chemical stability, higher rigidity and toughness, and good mechanical property, the plurality of advantages such as easy for installation, be widely used in building give, draining, the fields such as buried drain pipe, pneumatic tube and telecommunications engineering.
Polyethylene chemical stability is better, at ambient temperature can be acidproof, but the corrosion of not powerful oxidation corrosion resistance.But due to PE tubing self structure, its ageing resistance is poor, thus in use, improving its ageing resistance is one of index of most critical.Thus need to improve PE tubing, make it have good ageing resistance, extend working life and expansion use range.
The method improving PE tubing ageing resistance mainly adds photostabilizer or oxidation inhibitor in PE resin, or will both and use, by shielding UV-light, absorb UV-light, anti-light aging and thermal-oxidative aging property that the approach such as free radical, decompose hydroperoxide of catching improves PE and mixture thereof.But how selecting suitable anti-aging system to meet to require the anti ageing property of differing materials, is the key of problem.
Summary of the invention
This practicality invention technical problem to be solved is to provide a kind of anti-aging PE tubing, overcomes the defect of the anti-aging system instability of existing PE tubing.
In order to solve the problem, technical scheme provided by the invention:
A kind of anti-aging PE tubing, is characterized in that being made up of the raw material of following weight
Described antioxidant can be the one in 1,3,5-trimethylammonium-2,4,6-(3,5-di-t-butyl-4-hydroxyphenylmethyl) benzene, thio-2 acid two (stearyl alcohol) ester, butylated hydroxytoluene, butylated hydroxy anisole; Described ultraviolet screening agent can be the one in nano silicon, nano titanium oxide, nano-silicon nitride;
Described UV light absorber can be the one in 2-(2 '-hydroxyl-5 '-aminomethyl phenyl) benzotriazole, Octabenzone;
Described quencher can be the one in dithiocarbamic acid nickel salt, phosphine acid monoester ni-type.
Described radical scavenger can be the one in 2-methyl-2-nitrous butane, phenyl t-butyl oxynitrides, 2-ethoxycarbonyl-2-methyl isophthalic acid-pyrroline-N-oxide compound;
A kind of anti-aging PE tubing preparation method: add antioxidant, ultraviolet screening agent, UV light absorber, quencher and radical scavenger and mix in PE resin, heat and to extrude through twin screw extruder after 210 DEG C-240 DEG C, cooling vacuum is shaped.
PE polymkeric substance photooxidation mechanism: the photoaging of PE polymkeric substance is the autoxidation process in the presence of UV-light and oxygen, this process is otherwise known as photoxidation and photodegradation.Its process is divided into initiation reaction, transfer reaction and chain termination reaction three phases, along with the fracture of polymer molecular chain and crosslinked, causes the change of its mechanical property and outward appearance.The free radical generated again with polymkeric substance generation transfer reaction, make breaking polymer chains, generate new free radical, between free radical, then chain termination reaction occurs, polymkeric substance is occurred crosslinked.
The effect of ultraviolet screening agent absorbs or light reflection ultraviolet, make light can not direct projection to polymeric inner, thus suppress photoaging, the effect of UV light absorber is to absorb UV-light, and become by its energy conversion harmless heat energy to release, thus protection polymkeric substance is not by the initiation of UV-light; Quencher is also referred to as passivator, and its effect can be eliminated by energy from the polymer molecule of being excited (P-H), makes polymkeric substance get back to steady state from the excited state of instability, be not decomposed into living radical further; The effect of radical scavenger is then caught by the living radical (P, POO, PO, PCO) that excited polymer decomposes, and becomes stable compound, thus stops the further generation of oxidizing reaction.
Useful technique effect: (1) additive has good synergy each other, oxidation-resistance is strong, and volatility is little, good with PE resin-phase dissolubility; Do not affect material mechanical performance, high temperature resistant, Heat stability is good.
(2) insensitive to metal ion.
(3) selected additive is nonflammable, non-explosive, nontoxic, and use safety is harmless.
(4) absorb visible ray hardly, be specially adapted to water white transparency and light color article.
(5) there is strong sorption to UV-light, do not turn yellow under alkaline condition, oil resistant.
(6) volatility is low, and in the course of processing, loss is few.
(7) there is maximum provide protection to polymkeric substance, and contribute to reducing color and luster, delay yellowing and retardance loss of physical properties simultaneously.
