Abstract
The invention relates to a polypropylene high-filled toughening masterbatch and a preparation method thereof, and the preparation method comprises the following steps: taking ultra-fine active heavy calcium carbonate as a base, adding calcium carbonate powder, polypropylene resin, auxiliaries and a dispersing agent, carrying out activation and modification by a high-pressure gas flow machine, mixing, and carrying out extrusion molding for preparing the polypropylene high-filled toughening masterbatch. The filled masterbatch not only has large filling amount, but also still keeps the original excellent performances of plastic after filling, and improves the toughness, the rigidity and the smoothness of a product.
Description
Technical field
The present invention relates to a kind of polypropylene high-filled toughening masterbatch and manufacture method thereof.
Background technology
At present only have in the world a few countries such as the U.S., Germany, Japan, Korea S to have the technology and equipment of production high-performance powder, and have stronger advantage.The powder chemical industry of current China is to the demand of high-quality non-metallic mineral products dependence on import always.At present, the domestic powder activating modification process research and development professional system that also do not form is without specialized production base and market, the powder enterprises that some are domestic, its product is the initial stage starting material, and is of low grade, cause various resources to waste greatly, and can't change again the present situation of current backwardness.
Summary of the invention
The purpose of this invention is to provide that a kind of technique is simple, addition is large, the polypropylene high-filled toughening masterbatch of good dispersity and preparation method thereof.
The technical solution used in the present invention is: a kind of polypropylene high-filled toughening masterbatch, its composition and weight percentage are: calcium carbonate powder 84%, acrylic resin 7%, auxiliary agent 6%, dispersion agent 3%.
Wherein: auxiliary agent is that PP wax, PE are cured, mono-glycerides or Aluminate, and dispersion agent is calcium stearate.
2, a kind of method for preparing the described polypropylene high-filled toughening masterbatch of claim 1 comprises the steps:
1.1 common calcite through be processed into be at least 2000 purpose extra fine heavy calcium carbonate powder bodies after, through 8MPa high pressure draft machine activation modification, obtain a kind of superfine modified powder;
1.2 batching: by 150 kilograms of superfine modified powders, 4～8 kilograms of 14～17 kilograms of acrylic resins, 3.15～3.85 kilograms in PP wax, 2.25～2.75 kilograms in PE wax, 1.8～2.2 kilograms of mono-glyceridess, 1.8～2.2 kilograms of kilograms of Aluminate and calcium stearates are prepared burden
1.3 mixing: above-mentioned batching is fully mixing with it under 140～180 ℃,
1.4 granulation: the material after mixing is put into forcing machine again after overcooling, temperature is controlled at 180～240 ℃, after forcing machine rubs up evenly again, through the porous mill of head, rotary cutter is cut into particulate state while hot, and cooling namely gets described polypropylene high-filled toughening masterbatch.
The know-why of institute of the present invention foundation is: by the calcium carbonate superfine powder powder surface is accurately processed, make coating and interionic rely on physical method, weaken interionic agglomeration, tensio-active agent can accurately be controlled.The polypropylene high-filled toughening masterbatch of treated superfine modified calcium carbonate powder processing and fabricating has preferably dispersed, consistency, loading level reaches 40%-60% still can keep the original excellent properties of plastics, can significantly reduce plastic cement industry production cost after the use and can obtain goods preferably whiteness, mechanical property, rigidity, snappiness, abrasion resistance, anti-brittle failure etc.
The invention has the beneficial effects as follows:
1, increased loading level.When related products was filled, its loading level was brought up to present 40～60% by original 10～15%, had also improved simultaneously the correlated performance of product.
2, simplified production technique.Process only need with fine heavy activated Calcium carbonate powder by the activation of high pressure draft machine after after auxiliary agent, acrylic resin, dispersion agent are put into homogenizer and are mixed, extrude fervent granulating through twin screw extruder.
3, adopt water solvent, produce without waste liquid, so the waste discharge less investment has good environmental-protection function to environment.
