Description
Technical field
The present invention relates to the polyester resin particle for the raw material for being suitable for extrusion and blow molding, its manufacturing method and by it
Obtained molded product.
Background technique
The spies such as the transparency, mechanical characteristic, gas barrier property, the every flavour property of the polyester resin such as pet resin
Property is excellent.In addition, for polyester resin, wholesomeness few to the worry of residual monomer, harmful additive when forming molded product
It is also excellent with safety.Therefore, for polyester resin, their characteristic is efficiently used, was used always in the past as replacement
Vinyl chloride resin resin, be widely used as in recent years for holding fruit juice, cold drink, seasoning, oil, cosmetics, washing
The hollow container of agent etc. uses.
As the forming method for manufacturing the hollow molded article formed by polyester resin, it is known that following extrusion-blown modling at
Type method: it is squeezed out by die hole through the resin of melting plasticising as cylindric parison, is in the soft state phase in the parison
Between, it is clamped with mold, is internally blown into the fluids such as air and is formed.This method is compared with injection-blow molding forming method, work
Sequence is simple, and the production and molding of mold do not need the technology of height, therefore, cost of equipment, mold manufacturing cost etc. just
Preferably, it is produced on a small quantity suitable for multi items.Moreover, with thin object, deep object, big object, the complicated shape with handle etc. can also be manufactured
Molded product the advantage that.
On the other hand, the usual melt viscosity of general polyester resin is low, thus to carry out extrusion and blow molding, then it squeezes out
Drawdown obviously occurs for parison afterwards, it is difficult to carry out figuration.Therefore, for typically for extrusion-blown modling bottle laminac,
Assign resistance to drawdown using method for adding micro crosslinking agent etc., even if can form, the molded product that obtains sometimes it is resistance to
Impact is also insufficient.In addition, for typically for polyester resin, when carrying out melt molding or whens when solid phase etc.,
If be heated for a long time, it is easy to happen oxidation, yellow coloring occurs, molecular weight and molecular weight, generates the heat deteriorations such as gel-like constituent.
In order to solve these problems, in the past, it proposes about the polyester resin for being suitable for extrusion and blow molding, thermoforming etc.
Various motions.As one of such conventional art, it is known that the technology of addition hindered phenolic antioxidant is (referring to patent document 1
~3).
In patent document 1, a kind of copolyester is described, the copolyester is with terephthalic acid units, ethylene glycol list
Member and 1,4-CHDM unit are principal component, and the content of hindered phenolic antioxidant is 0.2~1.0 mass %, Germanium
Meet defined condition with the content of antimony element (catalyst).It is described in patent document 1 by using with defined composition
Catalyst and hindered phenolic antioxidant, can inhibit decomposition reaction when polymerization, polymerize and quickly carry out, tone, the transparency are not
Deteriorate, the polyester of high polymerization degree can be obtained, and may also suppress thermal decomposition when molding, therefore, after also not causing molding
Tone deteriorate.A kind of polyester and resin composition is described in patent document 2, in the polyester and resin composition, in 100 weight
In part polyester resin, be combined with 0.05~1 parts by weight hindered phenolic antioxidant, the polyester resin contain dicarboxylic acid units and
Diol units, 1~60 mole of % in diol units are the diol units with cyclic acetal skeleton.Moreover, in patent document 2
It describes by adding aforementioned antioxidant, can inhibit the generation of yellow coloring, gel component.However, by patent document 1 and 2
The impact resistance that the polyester resin of middle record carries out molded product obtained from extrusion and blow molding is insufficient.
Describe a kind of manufacturing method of particle formed by polyester and resin composition in patent document 3, in the method,
By carrying out melt polymerization, to respectively obtain of the polyester (A) based on terephthalic acid units and ethylene glycol unit
The particle of grain and the polyester (B) based on terephthalic acid units, ethylene glycol unit and cyclohexanedimethanol unit, then,
By the particle of polyester (A), the particle of polyester (B) and hindered phenolic antioxidant melting mixing, solid phase is then carried out.So
And this method is since process number is more, therefore, it is difficult to which productivity manufactures particle well.In addition, the molding obtained using the particle
The transparency of product is sometimes insufficient.
