Description
Technical field
The present invention relates to a kind of plastics filler and preparation method thereof, relate to a kind of organobentonite modified filler for plastics and preparation method thereof specifically.
Background technology
Calcium carbonate is a kind of important plastics filler, because it has the advantages such as cheap, nontoxic, stable chemical nature, it adds in plastics can play increment, reduce costs, improve product impelling strength, improve the effects such as dimensional stability, is therefore widely used in the plastic.
Because calcium carbonate is mineral ion, poor with the consistency of plastics, it is poor to its modified effect that calcium carbonate directly adds in plastics, therefore first calcium carbonate is processed into the consistency that filler parent granule significantly can improve calcium carbonate and plastics, therefore generally adopts calcium carbonate master batch to carry out modification to plastics.
Date of publication on May 25th, 2011, the Chinese invention patent of publication No. CN102070918A discloses a kind of preparation method of calcium carbonate master batch, this master batch forms by the Raw material processing of following mass parts: polyolefine 10-35 part, calcium carbonate 55-85 part, polyethylene wax 5-10 part, coupling agent, dispersion agent and thinner appropriate, the calcium carbonate master batch processed can be directly used in and polyolefin resin mixed injection molding, blending and modifying, but it still has more deficiency, this master batch is applied in and is fine in the not high plastics of performance requriements, but for the plastics that mechanical property requirements is higher, as resistance to compression, water resistance, the dispersiveness of this stopping composition or existing defects, add calcium carbonate-filled master batch amount more time (test find when addition >=30%), due to the defect of dispersiveness, the crushing resistance at each position of the plastics made there are differences, the streaking one of plastic prod, also there is flaw spot in plastics outside in addition.
Summary of the invention
The present invention is intended to solve the deficiencies in the prior art, provides the homogeneous organobentonite modified filler of mechanical property that a kind of dispersity is high, can meet Different adding amount requirement, plastics.
Another object of the present invention is the preparation method providing a kind of above-mentioned organobentonite modified filler.
The present invention solves its technical problem proposed by the following technical solutions:
For the organobentonite modified filler of plastics, described filler is formed by the Raw material processing of following weight part:
