Beverage-container of the present invention is to use the painted shaping resin that contains shaping resin and masterbatch and the beverage-container that is shaped, it is characterized in that masterbatch contains vibrin (A), surface-treated alpha-ferric oxide (B), as the hydroxycarboxylic acid metal-salt (C) and the methyne based dye (D) of dispersion agent
Surface-treated alpha-ferric oxide (B) is to coat the material that alpha-ferric oxide forms with polyvalent alcohol and organopolysiloxane.
The median size of the alpha-ferric oxide of Shi Yonging is 0.01~0.06 μ m in the present invention, preferred 0.03~0.05 μ m.During median size less than 0.01 μ m, may produce particles aggregate, disperse badly, when surpassing 0.06 μ m, the surfaceness that may have the shaping thing is excessive, and surface smoothing, the transparency reduce the bad order of the shaping thing that the alpha-ferric oxide aggegation causes.Here, median size be meant with minor axis, major diameter on average as particle diameter, show the peaked value of size-grade distribution.
And the alpha-ferric oxide of Shi Yonging is that aspect ratio is 0.2~1.0 non-acicular substance in the present invention, can open flat 8-59398 communique disclosed method by the spy and obtain.Here, said aspect ratio is meant the minor axis that utilizes electron microscope observation and the ratio (minor axis/major diameter) of major diameter.In order to obtain the shaping thing of the transparency, favorable dispersity, proper sphere shape (minor axis/major diameter=1.0) most preferably.
In the present invention, use polyvalent alcohol and organopolysiloxane surface treatment agent jointly as alpha-ferric oxide.
Utilize the surface-treated purpose of the alpha-ferric oxide of polyvalent alcohol to make particle surface hypopolarization and the aggegation again that prevents particle.
Object lesson as polyvalent alcohol, can exemplify out ethylene glycol, propylene glycol, 1, polyoxyalkylene diols such as aklylene glycols such as 3-butyleneglycol, tetramethylene glycol or glycol ether, triglycol, polyoxyethylene glycol, dipropylene glycol, tripropylene glycol, polypropylene glycol or glycerol, TriMethylolPropane(TMP), trihydroxy-ethane, tetramethylolmethane, sorbyl alcohol, 1,2, polyvalent alcohols such as 6-hexanetriol, Inositol nf12 99, polyvinyl alcohol.Preferred TriMethylolPropane(TMP) (TMP), trihydroxy-ethane (TME).These polyvalent alcohols can with a kind of or mix two kinds with on use.
The surface-treated purpose of utilizing the alpha-ferric oxide of organopolysiloxane is to make the particle surface hydrophobization, improves the wettability of particle and resin, suppresses reduction, the maintenance rerum natura of molecular resin amount.
As the object lesson of organopolysiloxane, can use various sex change polysiloxane such as polysiloxane such as dimethyl polysiloxane or methylhydrogenpolysi,oxane, methyl phenyl silicone, pure sex change polysiloxane, ether sex change polysiloxane, fluorine sex change polysiloxane.These organopolysiloxanes can with a kind or mix 2 kinds with on use.Preferable methyl hydrogen polysiloxanes, dimethyl polysiloxane.
And above-mentioned illustrative methylhydrogenpolysi,oxane is wished and can be represented with following formula.
(in the formula, n represents positive integer, and is preferred below 12.)
The amount of polyvalent alcohol and organo-siloxane is preferably with respect to the total amount of surface-treated alpha-ferric oxide (B), and 0.01~10 weight % respectively does for oneself.Surpass 10 weight %, do not have economy, and in manufacturing process, can produce polyvalent alcohol and organo-siloxane self decomposition etc., in the shaping thing of making, produce foaming and gathering etc.Less than 0.01 weight %, the polyvalent alcohol of iron oxide surface and the covering amount of organo-siloxane are insufficient, are unfavorable for the dispersion in resin, cause bad rerum natura in the shaping thing sometimes.More preferably 0.1~2 weight %, preferred especially 0.5~1 weight %.
The method that coats alpha-ferric oxide with above-mentioned surface treatment agent can be utilized known method such as wet processed or dry process.
Wet processed has alpha-ferric oxide and surface treatment agent added in the polar solvent of alcohol such as water or ethanol floods, after using high shear force mixing machines such as Henschel mixer, high-speed mixer to carry out the homogeneous mixing, revaporization, the dry method of desolvating of removing, or surface treatment agent is dispersed or dissolved in the solvent, then alpha-ferric oxide is mixed into the method for this solution etc.
In wet processed, in the surface treatment or when handling the back, preferably have the heat drying operation of alpha-ferric oxide, because can reduce the water content that moisture absorption etc. causes significantly.The ferric oxide of the low water content that so obtains be because during mixing dispersions, can suppress the resin deterioration in resin, suppress that the molecular resin amount reduces and the multiple advantages such as mechanical properties of maintenance shaping thing so have.
Dry process is added surface treatment agent when pulverizing alpha-ferric oxide with fluid energy pulverizer such as injector-type mill, micronizer mill or stirrers such as high-speed mixer, Henschel mixer.As the fluid of described fluid energy pulverizer, use pressurized air, heated compressed air, steam etc. usually.And, when polyvalent alcohol is solid at normal temperatures, the polyhydric alcohol solutions that is dissolved in the solvent can be used for above-mentioned treatment process.Can exemplify out as the ethanolic soln of TriMethylolPropane(TMP) or water-ethanol (1: 1) solution etc.
In the surface treatment of alpha-ferric oxide, utilize the preferred wet processed of coating of polyvalent alcohol, utilize the coating preferred dry of organopolysiloxane to handle.And, after the surface treatment, pulverize the agglutination particle that produces by surface treatment procedure with brute forces such as airflow milling, can improve dispersiveness more.
The surface treatment of alpha-ferric oxide can be used polyvalent alcohol and organopolysiloxane simultaneously, perhaps also can bring into use organopolysiloxane, and then uses polyvalent alcohol.
Can exemplify out moisture as one of alpha-ferric oxide agglutinative reason.Because the particle surface of alpha-ferric oxide has than higher wetting ability, so at first by coating the hydrophilic radical of handling particle surface with polyvalent alcohol, feasible effect with the moisture absorption that prevents operation subsequently.And the alpha-ferric oxide after polyvalent alcohol is handled is by heat drying, can reduce the water content that moisture absorption etc. causes significantly.
If coat alpha-ferric oxide after polyvalent alcohol is handled with the hydrophobicity organopolysiloxane, then can suppress particle aggegation again, obtain the surface-treated alpha-ferric oxide (B) of favorable dispersity.
And, surface-treated alpha-ferric oxide (B) with the operation of the thermoplastic resin melting mixing of polyester etc. in, can suppress thermal thermocoagulation, so can be scattered in well in the thermoplastic resin formed thing, the transparency raising aspect of shaping thing is good.
And the surface water component of the alpha-ferric oxide (B) that preferred surface is handled is few, because can suppress to add the influence to thermoplastic resin such as water decomposition.More preferably the amount of moisture less than 0.3%.
And the covering amount of above-mentioned surface treatment agent is by adopting known method, change the processing weight of alpha-ferric oxide and the supply concentration or the supply flow rate of surface treatment agent, thus it can be adjusted into fixed covering amount.
