Description
Technical field
The present invention relates to a kind of environmentally-friendly plastic material of good corrosion resistance.
Background technology
Plastic bottle mainly by the material such as polyethylene or polypropylene and with the addition of what is be made after a variety of organic solvents.Beverage bottle
Majority is plastic products, and both material non-toxics of polyethylene, polypropylene are tasteless, very safe to human body for filled drink etc..But
Polyethylene once will slowly be dissolved, and discharge organic solvent by high temperature or sour corrosion, will do harm to huamn body.
Being largely used to the plastic products of packaging for foodstuff has three kinds：Polyvinyl chloride, polyethylene, polystyrene.It is used for containing food in short time
Oil, is unobstructive to health.But, it is used to contain edible oil for a long time, meeting contaminated food products causes the danger to human body
Evil.Element vinyl chloride in polyvinyl chloride is not only poisonous, and is easy to decompose in acid and grease and to separate out toxicity very big
Hydrogen chloride and chlorine, such as plasticizer added in polyvinyl chloride, Phthalates are all toxic, also with used as stabilizers
Lead, cadmium and organotin, are all poisonous chemical substances, and toxicity is all larger, and is easily soluble in grease.Though plastic polystyrene
So belong to low toxicity material, still, its composition styrene and volatile ingredient ethylbenzene, isopropylbenzene is all poisonous and very soluble
In grease.Plastic polyethylene is in itself without toxicity.But, after it is contacted with grease, precipitation low molecular compound can be decomposed,
These low molecular elements, which are dissolved in grease, can produce toxicity.In recent years, country was directed to some disposable plastics, such as lunch box and bag
Package material, clear stipulaties should using easily reclaiming, can utilize, easily disposal or easily dissolved in natural environment, degradable production
Product.Up to the present, the existing 20 Duo Ge provinces and cities in the whole nation have successively put into effect disabling or have limited the use of the plastic foamed meal of ordinary polystyrene
Tool and less than 25 μm of common polythene packaging bag., will be big if 50% in plastic refuse is replaced using degradation plastic
Alleviate the pollution to environment greatly, therefore degradation plastic technology has larger Social benefit and economic benefit in China.
The content of the invention
The present invention provides a kind of good corrosion resistance with stronger shock resistance, inoxidizability and corrosion resistance advantage
Environmentally-friendly plastic material.
The technical scheme is that：A kind of environmentally-friendly plastic material of good corrosion resistance, comprises the following steps：By extruder
By resin melting plasticizing extrusion tubular parison, parison processing is then subjected to longitudinal stretching to preferable draft temperature, works as parison
When reaching certain length, parison is placed in blow mold, compressed air inflation is used, parison is close to mould inner wall and cool down and determine
Type, opens mould, takes out product, and the resin includes degradable plastic masterbatch, glass fibre, string, epoxy resin.
In a preferred embodiment of the present invention, the blow gas pressure is 0.25 MPa/s.
In a preferred embodiment of the present invention, the overall component of each composition of the resin be degradable plastic masterbatch account for 47%,
Glass fibre, which accounts for 21%, string and accounts for 11%, epoxy resin, accounts for 21%.
The present invention a kind of good corrosion resistance environmentally-friendly plastic material, with stronger shock resistance, inoxidizability and
The advantage of corrosion resistance.
Embodiment
Presently preferred embodiments of the present invention is described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that apparent clearly being defined so as to be made to protection scope of the present invention.
Wherein, comprise the following steps：By extruder by resin melting plasticizing extrusion tubular parison, then parison processing is arrived
Preferable draft temperature carries out longitudinal stretching, and when parison reaches certain length, parison is placed in blow mold, empty with compression
Air-blowing is swollen, parison is close to mould inner wall and cooling and shaping, opens mould, takes out product, and the resin includes degradation plastic
Master batch, glass fibre, string, epoxy resin.
Further illustrate, the blow gas pressure is 0.25 MPa/s, the overall component of each composition of resin is degradable plastic
Material master batch, which accounts for 47%, glass fibre and accounts for 21%, string and account for 11%, epoxy resin, accounts for 21%.
Further illustrating, the extruder temperature of blow molding process key control point 1.：Extrusion temperature general control 160 DEG C~
Between 170 DEG C, and it must assure that head temperature is uniform, extrusion temperature is too high, and resin is easily decomposed, and film embrittlement, especially makes
Longitudinal tensile strength is remarkably decreased;Temperature is too low, then Plastic is bad, it is impossible to sleekly carry out expansion stretching, the drawing of film
Stretch that intensity is relatively low, and the glossiness and poor transparency on surface, or even there is the decorative pattern and unfused crystalline substance as annual rings of timber
Core (flake).2. blow-up ratio is one of key control point of inflation film production technology, refer to that the diameter of film bubble is not with blowing after inflation
Ratio between swollen pipe ring diameter.Blow-up ratio is the lateral expansion multiple of film, is actually to carry out cross directional stretch to film,
Stretching can produce a certain degree of orientation effect, blow-up ratio increase, so that the transverse strength of film is improved to plastic molecules.But
It is that blow-up ratio can not be too big, it is unstable otherwise to easily cause film bubble, and fold easily occurs in film.Therefore, blow-up ratio should
Coordinate suitably with draw ratio, in general, the blow-up ratio of low density polyethylene (LDPE) (LDPE) film should be controlled 2.5~3.0
It is advisable.3. draw ratio refers to the ratio between the hauling speed of film and pipe ring extruded velocity.Draw ratio is longitudinal stretching
Multiple, make film draw take on direction have orientation.Draw ratio increases, then longitudinal strength can also be improved therewith, and film
Thickness it is thinning, but if draw ratio is excessive, the thickness of film is difficult to control to, it could even be possible to can break film, causes to break
Film phenomenon.The draw ratio general control of low density polyethylene (LDPE) (LDPE) film is advisable between 4~6.The present invention provides a kind of resistance to
The good environmentally-friendly plastic material of corrosivity, has the advantages that stronger shock resistance, inoxidizability and corrosion resistance.
The embodiment of the present invention, but protection scope of the present invention is not limited thereto, it is any to be familiar with this area
Technical staff disclosed herein technical scope in, the change or replacement that can be expected without creative work should all be contained
Cover within protection scope of the present invention.Therefore, the protection model that protection scope of the present invention should be limited with claims
Enclose and be defined.
