Abstract
The invention relates to the technical field of coloring of plastics and specifically relates to a blue masterbatch for coloring BOPS (biaxially oriented polystyrene) sheets and a preparation method thereof. The blue masterbatch comprises 60%-99% of carrier resin, 0.01%-2% of solvent type dye, 0.1%-28% of dispersant and 0.5%-20% of compatibilizer. The special blue masterbatch for the BOPS sheets is obtained through a physical or chemical method, and the blue masterbatch can prepare a base color of the BOPS sheets according to the requirements of customers. When the BOPS sheets are normally produced, the light yellow color of the BOPS sheets can be eliminated by adding the blue masterbatch, then the color of the sheets becomes light blue, and the transparency is increased; and by adopting the method, the production cost can be greatly reduced, the blue masterbatch can flexibly respond to the requirements of different customers on blue transparency of the sheets and the sanitary standard, the shutdown time is reduced, and the economic benefits are obvious.
Description
Technical field
The present invention relates to the coloring plastic technical field, be specifically related to a kind of blue master batch for the painted use of BOPS sheet material and preparation method thereof.
Background technology
The raw material polystyrene that present BOPS sheet production is used is generally General Purpose Polystyrenre (GPPS), and the BOPS sheet material primary colours that adopt GPPS to produce are faint yellow.Due to the general pure transparent BOPS sheet material of preference on market, and the partially yellow BOPS sheet material color after making Blister product of primary colours is still partially yellow, and the accumulation aberration that Blister product stacks generation makes the client often think that this BOPS sheet material is to have adopted sordid waste material production, and Huang is partially old partially.For the transparency that improves the BOPS sheet material and make after Blister product still transparent fine, start to adopt the polystyrene raw material of blue modification in the processing of BOPS sheet production, but the BOPS Blister product is mostly as food container, in case adopt the polystyrene raw material after blue modification will not meet export food packaging polystyrene products formed hygienic standard, and blue transparency is single non-adjustable.Therefore aforementioned production method is difficult to meet the requirement of client to blue transparency and hygienic standard in the face of different client the time, and blue modified polystyrene cost of material is more than the twice of GPPS simultaneously, causes higher production run cost.
Summary of the invention
The present invention, in order to solve the problems of the technologies described above the shortcoming of middle existence, provides special-purpose blue master batch of a kind of BOPS sheet material and preparation method thereof, and this blueness master batch can improve the transparency of BOPS sheet material and make Blister product afterwards still transparent fine.
The technical scheme that solves the problems of the technologies described above is:
The special-purpose blue master batch of a kind of BOPS sheet material consists of:
Further, described vector resin is one or both the mixture in GPPS, HIPS.
Further, described solvent dye is one or more the mixture in solvent blue 35, solvent blue 36, import solvent blue, transparent blue GP.
Further, described dispersion agent is one or more the mixture in polyamide wax (EBS), modification EBS, Poly Propylene Wax, polyethylene wax.
Further, described compatilizer is one or more the mixture in paraffin oil, turps, glycerine.
The preparation method of the special-purpose blue master batch of a kind of BOPS sheet material comprises the following steps:
(1) first vector resin is put in stirrer, then slowly add under stirring at low speed account for vector resin weight 0.55% ?25% compatilizer (weight percent), stir 10 ?30 minutes fully moistening to the vector resin surface, stop stirring;
(2) take account for vector resin weight 0.015% ?2.5% (weight percent) solvent dye and account for vector resin weight 0.15% ?the dispersion agent of 30% (weight percent), drop into the stirrer stirring at low speed to mixing;
(3) mixture that step (2) is made slowly adds in the vector resin that is wrapped with compatilizer that step (1) makes under stirring at low speed, stirring at low speed 10 ?30 minutes, treat that the vector resin surface uniform is enclosed with the mixture that step (2) makes, then high-speed stirring 2 ?5 minutes;
(4) the vector resin mixture that step (3) is made drops into vented extruder and carries out melt blending, temperature is controlled at 200-230 ℃, screw speed 30-60r/min,, by screw rod shearing, mixing making in the vector resin that solvent dye is dispersed in melting, then extrude tie rod pelletizing, drying, pack to obtain blue master batch.
Low speed and be at a high speed the conventional techniques means that those skilled in that art can regulate according to actual production situation.
Adopted such scheme, obtained the special-purpose blue master batch of a kind of BOPS sheet material, this blueness master batch can be allocated BOPS sheet material primary colours voluntarily according to customer requirement.Add a certain amount of blue master batch and can eliminate the faint yellow of BOPS sheet material when the BOPS sheet material is normally produced; make the sheet material color be little blueness; increase transparency; adopt this method greatly to reduce production costs; the requirement of the different clients of reply to the blue transparency of sheet material and hygienic standard flexibly; reduce stop time, economic benefit is obvious.
