Description
Technical field
The present invention designs a kind of big hollow blow molding (more than 200l) modification high-density polyethylene resin, further, is related to
A kind of relatively low yellow colour index, non-oxidizability preferable modification high-density polyethylene resin and preparation method thereof.
Background technology
Hollow plastic product because having the advantages that the aspects such as the big, recoverable of light weight, inexpensive, durable, design freedom,
Be increasingly entering the life of people, chemically reagent, the transport of pharmaceutical reagent, packaging arrive again daily life food,
The packaging of washing agent, cosmetics etc..Hollow container product is divided into Large Hollow Container (big by the size according to hollow container volume
In 200l), medium-sized container (20～200l), small containers (below 10l), with the fast development of automobile, packaging industry,
Plastic hollow product develops to specialized, variation, maximization, compared to middle-size and small-size plastic packaging containers, Bulk plastic bag
The features such as packaging container has convenient transportation, convenient in carrying, storage and freight are few, filling and discharge are convenient, Liquid Residue is few.
Therefore, Large Hollow Container will become one of important directions of following plastic packaging containers development.
Hdpe (high density polyethylene (HDPE)) is that a kind of degree of crystallinity is high, nonpolar thermoplastic resin, has excellent resistance to great majority
Life and the characteristic of chemicals for industrial use.With the fast development of packaging industry, plastic hollow product to specialized, variation,
Maximize development, compared to middle-size and small-size plastic packaging containers, Bulk plastic packing container have convenient transportation, convenient in carrying,
The features such as storage and freight are few, filling and discharge are convenient, Liquid Residue is few.Therefore, Large Hollow Container will become future
One of important directions of plastic packaging containers development.Ton packing plastics collecting barrelling (ibc) has uvioresistant, anti-aging, Yi Qing
Wash, non-toxic, creep resistance, the advantage such as wear-resistant, resisting environmental stress and cracking, can repeatedly use, in filling, accumulating
With during transport can not only reduces cost, and 28.3% memory space compared with 220l Plastic Drum, can be saved.
Import material used in the market mainly has a basell company lupolen4261, and 5261, philips company of the U.S.
Marlex-tr571, tr570, tr550, great Lin company of Korea S tr520 etc., domestic big hollow resin special material is mainly
Qilu Petrochemical dmd1158, Maoming Petrochemical tr580m, Dushanzi 5420, CSPC 4261 etc., some downstream producers also can
By a certain percentage domestic material is mixed with import material, the properties of product prepared are preferable and cost is relatively low, in actual production processing
During, ibc manufacturer reacts some products appearance yellowish, and compared with the resin that staving turns white, during anti-oxidant induction
Between also can decrease, in addition some producers select reclaimed materials produce more than 200l bucket, staving jaundice phenomenon more notable,
Thus affecting product appearance and service life.This phenomenon can be caused by many reasons, such as: heat, ultraviolet light, machinery should
Power, high-energy radiation, electric field etc., its result is that plastic material molecular structure changes.Yellow colour index be characterize water white transparency,
Translucent or subalbous macromolecular material deviates the degree of white, or the degree of jaundice, can intuitively reactor product face
Color situation, if on the occasion of representing that material is in yellow, negative value represents that material assumes blueness, due to the test of plastics yellow colour index
The yellow degree observed under sunlight with plastics can be coincide well, thus by the yellow colour index of test sample,
Can be used to evaluate the degree of macromolecule material aging, in laboratory, typically also judge the color distortion of resin with this numerical value.
The reason product turns to be yellow is probably base resin intrinsic colour Huang partially it is also possible to be that resin particle is subject in process engineering
Heat and the effect of shearing force and lead to product appearance to show slightly yellow, in order to ensure raw particles outward appearance examination criteria, in theory may be used
Its discoloration in granulation process is controlled with the method by adjusting auxiliary antioxidant, its difference with the primary antioxidant mechanism of action
It is that auxiliary antioxidant can suppress, delay the generation of free radical in elicitation procedure, hydroperoxide decomposition, passivation remains in
Metal ion in polymer, is contributed largely in process；And primary antioxidant then can be with free radical r., roo. reacts,
Interrupt the growth of living chain, be contributed largely in storing process.
Hollow blow molding product requirement raw material has good non-oxidizability, impact property and resisting environmental stress and cracking (escr) property
Can, there is good processing characteristics, stable parison and inflation performance simultaneously.High density polyethylene (HDPE) be a kind of degree of crystallinity high,
Nonpolar thermoplastic resin, has excellent resistance to great majority life and the characteristic of chemicals for industrial use, is difficult to be corroded, and
Water vapor that is non-hygroscopic and having had, can be used for packaging applicationss, in high molecular weight grades, there is fabulous impact resistance,
All such under normal temperature even -40f low temperature.Therefore high density polyethylene (HDPE) can become the resin dedicated basic material of big hollow.
Currently for the big hollow blow molding preparation method of modification high-density polyethylene resin, patent is all little with document.As:
The patent of invention of publication number cn102942733a (Application No. 201210411796.0), disclosed " a kind of big hollow container blows

0.03～0.05, focusing on by the various process conditions such as comonomer ethylene, hexene and catalyst of this patent, control
Make big hollow construct blow-molded and there is rational molecular weight, density and molecular weight distribution, the processing characteristics of adjustment resin and mechanical property
Can, product appearance color is not improved.
The patent of invention of publication number cn102432935b (Application No. 201010502795.8), a kind of disclosed " extrusion-blown modling
With modification high-density polyethylene composition and preparation method thereof ", this patent comprises the following components being blended: high density polyethylene (HDPE)
100 parts by weight, butylbenzene powdered rubber 0.5～15 parts by weight, lubricant 0.1～1.0 parts by weight, the weight of this patent
Point is to improve toughness and the processing characteristics of product by adding butylbenzene powdered rubber and lubricant, not to product appearance color
Improved.
The patent of invention of publication number cn102585324a (application number 201110009202.9), disclosed " one kind is improved yellow and is referred to
The polyethylene composition of number and glossiness and its manufacture method ", the polyethylene composition that this patent is related to is characterised by comprising 100
The polyethylene of mass parts, the antioxidant of 0.2～0.5 mass parts, the halogen-absorber of 0.05～0.3 mass parts and 0.05～1.0
The inorganic nanometer powder filler of mass parts, polyethylene composition has suitable with base-material or slightly raising mechanical property, heat
Performance and the yellow colour index being obviously reduced, and increase substantially surface gloss.But because nanoparticle surface can be larger,
It is not easy in the base to disperse, the reunion of particle affects the mechanical property of material.
