Description
Technical field
The present invention relates to packing material technical field, more particularly to a kind of preparation method of PVC packaging materials.
Background technology
Polyvinyl chloride, English abbreviation PVC is in initiators such as peroxide, azo-compounds；Or pressed certainly under light, heat effect
The polymer being polymerized by base polymerization reaction mechanism.Ryuron and vinyl chloride copolymer system are referred to as vinyl chloride tree
Fat；PVC is the white powder of impalpable structure, and the degree of branching is smaller, relative density 1.4 or so, 77 ~ 90 DEG C of glass transition temperature, 170
DEG C or so start to decompose, the stability to light and heat is poor, more than 100 DEG C or through long-time exposure in sunshine, will decompose and produce
Raw hydrogen chloride, and further autocatalysis is decomposed, and causes discoloration, physical and mechanical properties also declines rapidly, in actual applications must
Stabilizer must be added to improve the stability to light and heat.
Packaging film is main to be formed by the polyvinyl resin mixing extrusion of several different trades mark, and with puncture resistant, super-strength is high
Performance, packaging is wound to the goods being deposited on supporting plate, packing material is more consolidated clean and tidy, more superpower waterproof action, quilt
Widely use, in foreign export, papermaking, hardware, plastics chemical industry, building materials, food pharmaceuticals industry.
Polyvinyl chloride can be substituted reaction by ethene, chlorine and catalyst and be made.Due to the effect of its fireproofing and heat resistant, polyvinyl chloride
It is widely used in all trades and professions product of all kinds：Wire outer skin, optical cable coating, footwear, handbag, bag, jewelry, signboard and advertisement
Board, building decoration articles for use, furniture, ornament, roller, trunnion, toy, door curtain, rolling door, medical assistance articles for use, gloves, some foods
Tin foil.
Industrial PVC molecular weight is general in the range of 50,000~110,000, with larger polydispersity, molecular weight with
The reduction of polymerization temperature and increase；Without definite melting point, 80~85 DEG C start softening, and 130 DEG C are changed into viscoelastic state, and 160~180 DEG C are opened
Beginning is changed into viscous state；There are preferable mechanical performance, tensile strength 60MPa or so, there are excellent dielectric properties.
PVC was once the general-purpose plastics of yield maximum in the world, using widely.In construction material, industrial product, daily
In terms of product, flooring laminate, floor tile, artificial leather, tubing, electric wire, packaging film, bottle, expanded material, encapsulant, fiber
It is widely used.
PVC typically will first be modified granulation, be prepared into Screw Extrusion unit after particle, and plasticizing is more abundant, and processing is also more held
Easily, especially technique is the product of injection.Screw extruder is one of topmost equipment of plastics processing, and it passes through outside
Power transmits the Solid Conveying and Melting with the heat transfer progress plastics of external heat element, compacting, melting, shearing mixing extrusion shaping.Spiral shell
Strictly speaking bar extruder all occupies critical role as plasticizing granulation machinery or processing and forming machinery, there is special want
The PVC product asked, PVC modified formulas, makes to measure according to customer requirement.Also it is exactly the copolymerization in PVC production processes
Derivative, the kind of such modification has vinyl chloride copolymer, polyvinyl chloride blend and chliorinated polyvinyl chloride etc..
PVC is prepared with radical addition polymerization method, and polymerization is broadly divided into suspension polymerization, emulsion polymerization and sheet
Body polymerization, based on suspension polymerization, accounts for 80% or so of PVC total outputs.By pure water, liquefied VCM monomers, dispersant
It is added in reactor, then adds initiator and other auxiliary agents, is warming up to VCM monomers after certain temperature and occurs radical polymerization
Reaction generation PVC granule.Lasting stirring causes the epigranular of particle, and the particle of generation is suspended in water.In addition,
Also useful microsuspending method production PVC paste resin, properties of product and good into paste property.
Thermal stability of polyvinyl chloride and light resistance are poor.Start to decomposite hydrogen chloride at 150 DEG C, with plasticizer loading
How much generation adverse reactions.In addition, influence of the pigment to PVC, be embodied in pigment whether with PVC and composition PVC product its
Its component reacts and pigment resistance to migration itself, heat resistance.Some of colouring agent composition may promote resin
Degraded.If iron ion and zinc ion are the catalyst of polyvinyl chloride resin degradation reaction.Therefore, using iron oxide（It is red, yellow, brown and black）
Pigment or zinc oxide, zinc sulphide and lithopone off-white color pigment can reduce the heat endurance of polyvinyl chloride resin.Some colouring agents may
Had an effect with the catabolite of polyvinyl chloride resin.As ultramarine class pigment acid resistance it is poor, therefore PVC coloring process in, understand with
PVC, which decomposes the hydrogen chloride produced, to be occurred interaction and loses due color.Therefore for PVC colorings, it is contemplated that used
The feature of resin and related auxiliaries, with reference to the characteristics of pigment.
PVC material is a kind of amorphism material.PVC material is frequently added stabilizer in actual use, lubricant, auxiliary
Helps processing agent, colorant, impact modifier and other additives.PVC material have low flammability, high intensity, resistance to climate variability with
And excellent geometrical stability.PVC has very strong resistance to oxidant, reducing agent and strong acid.But it can be by dense oxygen
Change the acid such as concentrated sulfuric acid, concentrated nitric acid and corrode and also do not apply to the occasion contacted with aromatic hydrocarbon, chlorinated hydrocabon.PVC is molten in processing
It is a very important technological parameter to change temperature, if this parameter is improper will to cause the problem of material is decomposed.PVC flowing is special
Property is mutually on duty, and its processing range is very narrow.The PVC material of particularly macromolecule is more difficult to processing, therefore usually used is all
The PVC material of small-molecular-weight.PVC shrinkage factor is at a fairly low, and generally 0.2 ~ 0.6%.
