Description
[technical field]
The present invention relates to field of plastic coloring, relate in particular to a kind of universal white master batch and preparation method thereof.
[background technology]
The method of coloring plastic have toner painted, dyeing painted, the painted three kinds of methods of Masterbatch.Directly toner is painted very simple, but has shortcomings such as color dot, aberration, production environment pollution.Dyeing granulation coloring effect is good than toner, but cost height and material can descend through heat treatment performance to some extent.The employing Masterbatch is painted, and the pigment process is pre-dispersed, and is evenly dispersed in the vector resin, and it is low to have improved dispersing of pigments property and coloration efficiency and cost widely, environmentally safe.
Coloring plastic is many because of the color of kind; Material different is not quite similar to the requirement of Masterbatch; The Masterbatch that causes same manufacturer to use is various in style, and the material of a plurality of parts on a product just needs to use a plurality of special color master batch not simultaneously especially.Like this links such as the monitoring of quality product, warehousing management buying all there is higher requirement, thereby causes the increase of the production cost of manufacturer, fraction defective also to raise greatly.
Under such market background, a kind of general Masterbatch of high density has just appearred on the market.The characteristics of general Masterbatch are that same Masterbatch can use in multiple plastics, thereby have remedied the deficiency of special color master batch, and its addition few (being generally 1%), thereby favor in the painted market that extensively receives with low cost.But along with plastics industry constantly develops; Various engineering plastic applications scope constantly enlarges; Existing general Masterbatch and preparation technology thereof can not satisfy the demand of plastics at aspects such as physical strength and dispersivenesses, and main because existing general Masterbatch bad dispersibility, whiteness are low, and mostly its carrier is Vilaterm; Though it is good with Vilaterm, polyacrylic consistency; But poor with the consistency of acrylonitrile-butadiene-phenylethylene multipolymer (ABS), PS (PS), HTPS (HIPS), so when the general Masterbatch that with the Vilaterm is carrier added in the above-mentioned materials, material occurred very easily that flow liner, whiteness are low, degradation phenomenon under the impact property.Particularly require highly when product whiteness, surface gloss, like white domestic appliances etc., along with the increase of existing general Masterbatch addition, then above-mentioned phenomenon can be more serious, directly has influence on the quality of the finished product.
[summary of the invention]
The technical problem that the present invention will solve provides a kind of good dispersivity, universal white master batch that whiteness is high; This Masterbatch can use main general-purpose plastics painted, can overcome to use the painted the finished product of traditional common Masterbatch to produce flow liner, whiteness is low, impact property descends shortcoming.
The technical problem of another solution of the present invention provides a kind of preparation method of above-mentioned general Masterbatch.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopts is, a kind of universal white master batch is composed of the following components by weight percentage:

The above universal white master batch preparing method's technical scheme may further comprise the steps:
Weight percent by above-mentioned takes by weighing raw material, and raw material is carried out low speed pre-mixing 5-15min in mixing machine, then at mixed at high speed 5-25min; Adopt the twin screw extruder melt blending, disperse equably in vector resin through the shearing of screw rod, the mixing pigment that makes, and then carry out granulation, drying, make Masterbatch of the present invention.
Universal white master batch good dispersivity of the present invention, whiteness height; Can be used to multiple coloring plastics such as Vilaterm, Vestolen PP 7052, PS, high-impact polystyrene, acrylonitrile-butadiene-phenylethylene multipolymer; With good by the consistency of coloured plastics; The finished product do not have flow liner, whiteness is high, impact property is good, are particularly suitable for being applied to whiteness, the demanding white domestic appliances product of surface gloss.
[embodiment]
In following embodiment, vector resin is Vilaterm-ethylene butene-styrol copolymer and ethylene vinyl acetate.The flow rate of Vilaterm-ethylene butene-styrol copolymer melt is 7.5-8.5g/10min under 230 ℃/2.16kg condition, selects Sumitomo chemical industry SEBS for use; The flow rate of ethylene vinyl acetate melt is 4.5-5.5g/10min under 230 ℃/2.16kg condition, and ethylene vinyl acetate is selected DSM EVA for use.These polymkeric substance all have good consistency as vector resin and Vilaterm (PE), Vestolen PP 7052 (PP), PS (PS), high-impact polystyrene (HIPS), acrylonitrile-butadiene-phenylethylene multipolymer (ABS) etc.: because of its molecule has fabulous kindliness; Thereby adding is the general Masterbatch of carrier with this polymkeric substance; The impact property of product can not significantly decrease can play the effect toughness reinforcing to body material on the contrary; The processing characteristics of this vector resin is good, can improve the interpolation content of pigment greatly.
Pigment is one or both the mixture in Rutile type Titanium Dioxide or the anatase thpe white powder, and above-mentioned white titanium pigment is Rutile type Titanium Dioxide R706 of Du Pont or R900.White titanium pigment has that fabulous light stability, specific refractory power are high, opacifying property is good and tinctorial strength is high has pure white advantages such as color and luster, is applied to the performances such as outward appearance and shading that product particularly can be given the product grace in the white domestic appliances.
Dispersion agent is one or both the mixture in polyethylene wax, the OPE, and polyethylene wax and OPE are low-molecular-weight wax, molecular weight ranges 500-1000.The preferential fusion and be coated on surface of pigments in the course of processing of these low-molecular-weight components can be played and promotes dispersing of pigments to process the lubrication that is.
Processing aid is one or both the mixture in stearate or the ethylene bis stearic amide.Like Zinic stearas S400, Korea S EBS120.This processing aid can play lubrication, reduces the skin friction force of material and barrel, mould, increases the surface gloss of product and solves the difficult problem of product stripping
Thermo-stabilizer is a kind of in phenol antioxidant or the phosphorous acid esters.Phenol antioxidant is like PHT, 1010,1076; Phosphorous acid esters are as 168, and the adding of thermo-stabilizer can prevent the degraded of resin in the Masterbatch course of processing and the jaundice of pigment effectively, thereby reach the stability that keeps the Masterbatch color.
Coupling agent is silane coupling agent KH-560, can effectively handle the inorganics surface, makes filler and white titanium pigment and resin compatible good.
Weighting agent is one or more the mixture in lime carbonate, talcum powder or the wollastonite, and said weighting agent is active 2500 orders.Weighting agent can reduce cost and prevent the thermal contraction of product effectively, keeps the dimensional stability of product.
