Above-mentioned a kind of preparation method for poly high performance filled master batch, comprises the following steps:
(1), each component is weighed up stand-by by weight ratio;
(2), polyethylene, compatilizer, dispersion agent, coupling agent and oxidation inhibitor are added to high speed agitator stirring at low speed 1～3 minute;
(3) add, more compound acicular powder and process white, after mixing with step (2) in high speed agitator high-speed stirring 10～15 minutes;
(4), zeolite powder is added in the mixed material of step (3), in high speed agitator stirring at low speed 2～5 minutes;
(5) material, after step (4) is stirred adds that twin screw extruder is extruded, after granulation, drying, pack and obtain a kind of for poly high performance filled master batch.
The invention has the beneficial effects as follows:
1, the present invention adopts polyethylene as carrier, can eliminate polyethylene is carried out to the bad problem of improved consistency, also can significantly reduce the cost of master batch simultaneously.
2, the present invention adopts the inorganic powder filler of compound acicular powder, process white and zeolite powder blend, make the filling-modified polyethylene products of this master batch there is high-performance, high brightness and absorption function of odor removal strong, obviously enhance product performance, its comprehensive mechanical property is good, surface-brightening is attractive in appearance, and taste removal is effective.
3, the compound acicular powder that the present invention adopts has wollastonite (acicular structure) and talcum powder or rhombspar (laminate structure) apokoinou construction, there is good toughening functions and transparent functional, and surface activation process (oil-absorption(number)) and dispersiveness and processing fluidity in resin, significantly better than wollastonite, so be filled into PE modified, its comprehensive mechanical property having is better than wollastonite, processing characteristics is good more than talcum powder, suitable with pearl filler, its mobility (screw torque or strength of current) is better than pearl filler, and the in the situation that of same particle size and identical loading level, comprehensive mechanical property index is significantly better than pearl filler, good toughness compared with talcum powder.
4, the present invention adopt the particle diameter of process white little, narrowly distributing, oil-absorption(number) is low, in the situation that loading level is no more than 15%, does not only reduce the intensity of goods, can also improve the surface brightness of goods.
5, Ben Fafa adopts zeolite powder to have fresh-keeping, deodorizing and air purification function, because zeolite powder structure is porous network structure, specific surface area is large, so adsorptive power is extremely strong, can adsorb many kinds of metal ions and gas, and other inorganic mineral powders of the density ratio of zeolite powder are little.Utilize the distinctive reticulated structure of zeolite powder, bigger serface, strong adsorptivity and low-density characteristic, for filling-modified vinyon, can make that mechanical strength is good, weightening finish amplitude is little and have the goods of the functions such as absorption taste removal.
