Description

Universal white master batch and preparation method thereof
Technical field
The present invention relates to field of plastic coloring, be specifically related 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 to some extent through heat treatment performance.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 and coloration efficiency and cost widely, environmentally safe.
But coloring plastic is many because of the color of kind, and different materials is not quite similar to the requirement of Masterbatch.The Masterbatch that so just 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 to the monitoring of quality product, warehousing management buying etc. all link higher requirement is all arranged, thereby cause 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 is few
(being generally 1%), thus favor in the painted market that extensively is subjected to 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, main because existing general Masterbatch bad dispersibility, concentration is low, and its carrier mostly is polyethylene, though with polyethylene, polyacrylic consistency is good, but with acrylonitrile-butadiene-styrene copolymer (ABS), polystyrene (PS), the consistency of high-impact polystyrene (HIPS) is poor, so when the general Masterbatch that with the polyethylene is carrier added in the above-mentioned materials, peeling very easily appearred in material, layering, degradation phenomenon under the impact property.Particularly require highly when product whiteness, surface gloss, as 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 to be solved in the present invention is to provide the universal white master batch that a kind of dispersiveness is high, shock-resistant, concentration is high, it is painted that this Masterbatch can be used for polyethylene (PE), polypropylene (PP), polystyrene (PS), high-impact polystyrene (HIPS), acrylonitrile-butadiene-styrene copolymer five big general-purpose plastics such as (ABS), can overcome degradation shortcoming under peeling that the product that uses the traditional common Masterbatch easily produces, layering, the impact property.
Another technical problem that the present invention solves provides a kind of preparation method of above-mentioned general Masterbatch.
Universal white master batch of the present invention is made up of the component of following weight percentage: vector resin 15～20%, pigment 40～80%, dispersion agent 5～10%, processing aid 0～5%, thermo-stabilizer 0～2%, weighting agent 0～40%.
Above-mentioned vector resin is one or both the mixture in polyethylene-ethylene butene-styrol copolymer and the ethylene vinyl acetate.These polymkeric substance all have good consistency as vector resin and polyethylene (PE), polypropylene (PP), polystyrene (PS), high-impact polystyrene (HIPS), acrylonitrile-butadiene-styrene copolymer (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 and can play the effect toughness reinforcing to body material on the contrary, and the processing characteristics of this vector resin is good, can improve the interpolation content of pigment greatly.
Above-mentioned pigment is one or both the mixture in Rutile type Titanium Dioxide or the anatase thpe white powder.Titanium dioxide has fabulous light stability, specific refractory power height, opacifying property is good and tinctorial strength is high has pure white advantages such as color and luster, is applied to product and particularly can gives performances such as the outward appearance of product grace and shading in the white domestic appliances.
Above-mentioned dispersion agent is one or both the mixture in polyethylene wax, oxidized polyethlene wax or three kinds of materials of ethylene-vinyl acetate copolymer wax.The preferential fusion and be coated on surface of pigments in the course of processing of these low-molecular-weight components can be played the lubrication that promotes dispersing of pigments and add man-hour.
Above-mentioned processing aid is one or both the mixture in stearate or the ethylene bis stearamide.As Zinic stearas.This processing aid can play lubrication, reduces the skin friction force of material and barrel, mould, increases the surface gloss of product and the problem that solves the product stripping difficulty.
Above-mentioned thermo-stabilizer is a kind of in phenol antioxidant or the phosphorous acid esters.Phenolic antioxidant is as BHT, 1010,1076; Phosphorous acid esters are as 168.The adding of thermo-stabilizer can prevent the degraded of resin in the Masterbatch course of processing and the jaundice of pigment effectively, thereby reaches the stability that keeps the Masterbatch color.
Above-mentioned filler is one or more the mixture in lime carbonate, talcum powder or the wollastonite.Filler can reduce cost and prevent the thermal contraction of product effectively, keeps the dimensional stability of product.
The preparation method of universal white master batch of the present invention is: each component is prepared burden in proportion, in mixing machine, carry out low speed pre-mixing 0～10min, and then high-speed mixing 5～25min, adopt the twin screw extruder melt blending to extrude, temperature is controlled at 190～220 ℃, rotating speed is within 80～400r/min, is uniformly dispersed in vector resin by the shearing of screw rod, the mixing pigment that makes, and carries out granulation then, drying obtains universal white master batch of the present invention.
Remarkable advantage of the present invention and beneficial effect: the present invention adopts the mixture of polyethylene-ethylene butene-styrol copolymer and ethylene vinyl acetate to replace polyethylene of the prior art and does carrier, the Masterbatch of preparation have high dispersive, shock-resistant, concentration is high and the advantage of the highly versatile in different materials, has avoided degradation phenomenon under peeling that material in use is prone to, layering, the impact property.
