Description
Technical field
The present invention relates to PE field of material technology, particularly relate to a kind of PE agricultural film and preparation method thereof.
Background technology
The performance of polyethylene depends on its polymerization methods.That carry out under middle pressure (15-30 atmospheric pressure) organic compound catalytic condition that Ziegler-Natta is polymerized is high density polyethylene (HDPE) (HDPE).Under the conditions of this, the polyethylene molecule of polymerization is linear, and strand is the longest, and molecular weight is up to hundreds of thousands.If in high pressure (100-300MPa), high temperature (190 210C), radical polymerization under the conditions of peroxide catalyzed, that produce is then Low Density Polyethylene (LDPE), and it is side chain chemical combination structure.
Polythene material is difficult to printing (unless carrying out this modifies or surface modification), therefore is colourless or light color article mostly, has good resistance to environmental aging performance due to it the most again, and the artificial turf on sports ground is manufactured by polyethylene mostly.Simplest discrimination method lights a fritter sample, sample meeting sustained combustion with gas burner (such as lighter) exactly, has cigarette, and has the taste burning wax candle.With fingernail the most standardized under, have cut for Low Density Polyethylene (LDPE), the most then be high density polyethylene (HDPE) (HDPE).
Polyethylene is typical thermoplastic, is odorless, tasteless, nontoxic flammable white powder.The PE resin of processing and forming is all the wax-like particulate material of extruded pelletize, and outward appearance is creamy white.Its molecular weight is in the range of 10,000 one loa ten thousand.Molecular weight is then ultra-high molecular weight polyethylene f UHMWPE3 more than 100,000.Molecular weight is the highest, and its physical and mechanical property is the best, closer to the requirement level of engineering material.But molecular weight is the highest, the difficulty of its processing increases the most therewith.Polyethylene fusing point is that its resistance to low temperature of 100-130C is excellent.At-60 DEG C, still can keep good mechanical property, but use temperature at 80 ~ 110 DEG C.
Polyethylene chemical stability is preferable, is resistant to the solution such as dust technology, dilute sulfuric acid and the hydrochloric acid of any concentration, Fluohydric acid., phosphoric acid, formic acid, acetic acid, ammonia, amine, hydrogen peroxide, sodium hydroxide, potassium hydroxide under room temperature.But the not corrosion of powerful oxidation corrosion resistance, such as the mixed liquor of oleum concentrated nitric acid, chromic acid and sulphuric acid.The most above-mentioned solvent can produce corrosion function slowly to polyethylene, and at 90-100 DEG C, concentrated sulphuric acid and concentrated nitric acid can corrode polyethylene rapidly so that it is destroys or decomposes.
Polyethylene is under the effect of air, sunlight and oxygen, it may occur that aging, variable color, chaps, becomes fragile or efflorescence, loses its mechanical property.At a temperature of processing and forming, also can be because of Oxidation so that it is melt degree of killing declines, there is variable color, striped occurs, so should give attention when processing and forming and use process or selection.Just because of polyethylene has as above speciality, being easily worked molding, therefore the regeneration of polyethylene is reclaimed and is had the most far-reaching value.
