Description
Technical field
The present invention relates to the preparation method of a kind of aging resistance low-density polyethylene film, belong to plastic technology of preparing neck
Territory.
Background technology
Low Density Polyethylene is the thermoplastic resin that a kind of degree of crystallinity is relatively low, english abbreviation LDPE, the general 5-50 of molecular weight
Ten thousand, density is 0.910-0.9259/cm3, and softening point is relatively low, and moulding processability is fine, and flexibility is good, toughness,
Lower temperature resistance is fine, can be at-60 DEG C--work at 80 DEG C.The mechanical strength of LDPE is poor, and thermostability is the highest, and chemical stability is excellent
Show, the most stable to acid, alkali, salt, organic solvent.LDPE is mainly used for making film product, as thin in agricultural film, daily packaging
Film, Archtectural Coatings, industrial film etc..Additionally, LDPE is additionally operable to injection-molded item, such as everyday articles, medical apparatus, extruded pipe,
Sheet material, container, electric wire etc.；
Low Density Polyethylene is easy thermo-oxidative ageing and photooxidation resistance under daylight and heat effect, and these ageing results cause low
Density polyethylene generation degradation reaction is main irreversible chemical reaction, and makes its performance depreciation or even completely lose use valency
Value.Low Density Polyethylene is inflammable, can burn away after fire, can melt during burning, has liquid to drip.
Wollastonite raphioid fiber is a kind of anorthic system, thin platelike crystal, and aggregation, in radiation needle-like or threadiness, is to mould
Material, rubber preferable aging resistance packing material, can improve plastics, the impact strength of rubber, strengthen mobility with
And improve tensile strength, impact strength, linear stretch and mould shrinkage factor, nontoxic, resistance to chemical attack, heat stability and dimensionally stable
Well, there are glass and pearly luster, low water absorption and oil factor, mechanical property and electrical property excellent and there is certain reinforcement work
With.
White carbon can uv reflectance consumingly, add to and polyvinyl resin can greatly reduce ultraviolet to polyethylene
Degradation, thus reach to delay the purpose of material aging.Silica particles is less 100 1000 times than SiO2, is added
It is added in polyvinyl resin, is conducive to melted membrane.Due to high fluidity and the small-size effect of white carbon, make material surface more
Add densification the cleanest, in addition the high intensity of nano-particle, make film strength be greatly enhanced.
Montmorillonite is a class by the surface of nano thickness electronegative silicate lamella, relies on the electrostatic interaction of interlayer and heap
The long-pending earthy mineral together constituted, the structure cell in its crystal structure is by one layer of alumina octahedral of folder in the middle of two-layer silicon-oxy tetrahedron
Body is constituted.There is one-dimensional layered nano-structure and the cation commutativity characteristic of uniqueness, thus give the many modifications of montmorillonite
May be with the expansion of application.The montmorillonite being modified has a strongest absorbability, and good dispersive property can be extensive
Application macromolecular material industry, as the additive of nanometer polymer macromolecular material, improves shock resistance, resisting fatigue, dimensionally stable
Property and gas barrier property etc., thus play the effect strengthening polymer comprehensive physical performance, improve materiel machining performance simultaneously.
Application in the polymer can be added when polymer, it is also possible to is blended when melted and adds.
Whisker is the diameter the least (0.1-10um) with single crystal form growth, atomic arrangement high-sequential, intensity
Close to perfect crystal theoretical value, have the fibrous material of certain draw ratio (5-1000), add in thermoplastic macromolecule material
A small amount of whisker, just not only can strengthen but also toughness reinforcing, also can improve other performances such as thermostability.
Magnesium borate crystal whisker has another name called pyroboric acid magnesium whisker, and outward appearance is white fluffy solid, and basis of microscopic observation is threadiness
Crystal, diameter 0.2-10 μm, length 10-100 μm, price is only the 1/20-1/30 of silicon carbide whisker, be current composite
It is hopeful one of wide variety of whisker.It is widely used in military affairs, aviation with the composite of whisker reinforcement in developed country
Space material, building, machinery, bridge, automobile, macromolecular material, sports equipment and aluminum base, magnesium base alloy strengthen, and plastics are multiple
The fields such as condensation material strengthens, and ceramic composite strengthens, macromolecular material enhancing.Magnesium borate crystal whisker have lightweight, high intensity,
High elastic modulus, high rigidity, the excellent properties such as high temperature resistant, corrosion-resistant and good mechanical strength and electrical insulating property, nontoxic nothing
Evil is pollution-free.Magnesium borate crystal whisker reinforced plastics molding good fluidity, close to packless resin, whisker can reach appointing of parts
Meaning corner, has the advantages such as high, strong, the smooth surface of part stability of formed precision.Plastics with magnesium borate crystal whisker as reinforcement
Material has been succeeded application on accurate engineering plastics parts and ultra-thin-wall zero device.The resistance to highly basic of magnesium borate crystal whisker,
Solvent has good dispersibility, is suitable for further surface and processes.
Aluminium borate whisker is a kind of whiskers fiber, belongs to the crystal of structure of right angle intersection, diameter 0.5-1 μm, length 10-
30μm.This whisker has high elastic modelling quantity, good mechanical strength, thermostability, chemical proofing, acid resistance, electricity absolutely
